FUNCTIONS OF AN ECOSYSTEM

 

ENERGY FLOW- Energy is the basic force responsible for all metabolic activities. The flow of energy from producer to top consumers is called energy flow  which is unidirectional.

Energy flows through the trophic levels: from producers to subsequent trophic levels. There is a loss of some energy in the form of unusable heat at each trophic level.

The trophic level interaction involves three concepts namely :-

  1. Food Chain
  2. Food Web
  3. Ecological Pyramids
  4. FOOD CHAIN- A food chain starts with producers and ends with top carnivores. The sequence of eaten and being eaten, produces transfer of food energy and it is known as food chain.

Grazing food chain-The consumers which start the food chain, utilising the plant or plant part as their food, constitute the grazing food chain.

This food chain begins from green plants at the base and the primary consumer is herbivore

For example, In terestrial ecosystem, grass is eaten up by caterpillar, which is eaten by lizard and lizard is eaten by snake.

In Aquatic ecosystem phytoplanktons (primary producers) is eaten by zoo planktons which is eaten by fishes and fishes are eaten by pelicans

Detritus food chain- The food chain starts from dead organic matter of decaying animals and plant bodies to the micro-organisms and then to detritus feeding organism called detrivores or decomposer and to other predators.

 

Litter —■Earthworms —■Chicken—■Hawk

Detritus food chain

The distinction between these two food chains is the source of energy for the first level consumers.

  1. FOOD WEB

“A food web illustrates, all possible transfers of energy and nutrients among the organisms in an ecosystem, whereas a food chain traces only one pathway of the food”.

  1. ECOLOGICAL PYRAMIDS

The steps of trophic levels expressed in a diagrammatic way are referred as

ecological pyramids.

 

The food producer forms the base of the pyramid and the top carnivore forms the tip. Other consumer trophic levels are in between.

The pyramid consists of a number of horizontal bars depicting specific trophic levels which are arranged sequentially from primary producer level through herbivore, carnivore onwards.  The length of each bar represents the total number of individuals at each trophic level in an ecosystem.

The ecological pyramids are of three categories-

1.Pyramid of numbers,

2.Pyramid of biomass, and

3.Pyramid of energy or productivity

  1. Pyramid of Numbers

This deals with the relationship between the numbers of primary producers and consumers of different levels. Depending upon the size and biomass, the pyramid of numbers may not always be upright, and may even be completely inverted.

(a) Pyramid of numbers – upright

In this pyramid, the number of individuals is decreased from lower level to higher trophic level.

This type of pyramid can be seen in grassland ecosystem.

(b) Pyramid of numbers – inverted

In this pyramid, the number of individuals is increased from lower level to higher trophic level.

A count in a forest would have a small number of     large producers, for e.g. few number of big trees.   This is because the tree (primary producer) being

few in number and would represent the base of the pyramid and the dependent herbivores  (Example – Birds) in the next higher trophic level and it is followed by parasites in the next trophic level. Hyper parasites being at higher trophic level represents higher in number.

A pyramid of numbers does not take into account the fact that the size of organisms being counted in each trophic level can vary

the pyramid of number does not completely define the trophic structure for an ecosystem.

  1. Pyramid of Biomass

In this approach individuals in each trophic level are weighed instead of being counted. This gives us a pyramid of biomass, i.e., the total dry weight of all organisms at each trophic level at a particular time.

Biomass is measured in g/m2.

 

(a) Upward -pyramid For most ecosystems on land, the pyramid of biomass has a large base of primary producers with a smaller trophic level perched on top

 

(b) Inverted pyramid-In contrast, in many aquatic ecosystems, the pyramid of biomass may assume an inverted form

  1. Pyramid of Energy

To compare the functional roles of the trophic levels in an ecosystem, an energy pyramid is most suitable.

An energy pyramid, reflects the laws of thermodynamics, with conversion of solar energy to chemical energy and heat energy at each trophic level and with loss of energy being depicted at each  transfer to another trophic level.

Hence the pyramid is always upward, with a large energy base at the bottom.

POLLUTANTS AND TROPHIC LEVEL

 

Movement of these pollutants involves two main processes:

 

  1. Bioaccumulation

refers to how pollutants enter a food chain. there is an increase in concentration of a pollutant from the environment to the first organism in a food chain.

 

  1. Biomagnification

refers to the tendency of pollutants to concentrate as they move from one trophic level to the next.  there is an increase in concentration of a pollutant from one link in a food chain to another.

In order for biomagnification to occur, the pollutant must be: long-lived, mobile, soluble in fats, biologically active.

If a pollutant is not active biologically, it may biomagnify, but we really don’t worry about it much, since it probably won’t cause any problems Examples : DDT.

  • Ambo Declaration was adopted
    • It calls for more and immediate action to be undertaken to address the causes and adverse impacts of climate change.

CoP-16/CMP-6, Cancun

COP-16 President: Patricia Espinosa, Mexico’s foreign secretary

COP-17 will be held in Durban

Issues

  • Forestry issues and reducing emissions from deforestation and forest degradation (REDD) plus
  • The developed countries are pushing for transparency from countries where they will fund climate change mitigation.
    • The assessment of carbon emission mitigation for developing countries is right now through domestic communication but is subject to international consultation and analysis. This push for transparency is a major contentious issue.
  • Fast-track finance: $ 30 bn had been committed at CoP-15. A large part of this funding is yet to come through.

 

Goals

Agreements Reached

  • The outcome of the summit was an agreement, not a binding treaty, which calls on rich countries to reduce their greenhouse gas emissions as pledged in the Copenhagen Accord, and for developing countries to plan to reduce their emissions, to limit global warming to less than 2 degrees celsius above pre-industrial levels.
  • There should be no gap between the first commitment period of the Kyoto Protocol, which expires in December 2012, and the second phase.
  • The agreement calls on the developed countries to “raise the level of ambition of the emission reductions to be achieved by them individually or jointly, with a view to reducing their aggregate level of emission of green house gases”
  • Allows flexibility in choosing the base year for setting emission reduction targets
  • Emissions trading and the project based mechanism under the KP shall continue to be available to Annex 1 parties as a means to meet their quantified emission limitation and reduction objectives.
  • The agreements recognize that in all climate change related action, human rights must be respected. They also recognise the need to engage with a broad range of stakeholders, including youth and persons with disability, and call for gender equality and effective participation of women and indigenous people in effective action on all aspects of climate change.
  • The BASIC group softened the three demands it had before the talks began
    • Necessity of a second commitment period to the Kyoto Protocol
    • Need to accelerate disbursement under the fast start finance in the form of new and additional resources through a multilaterally supervised mechanism
    • Continued dialogue on IPRs as part of the technology development and transfer issues.
  • REDD is a part of the package and proposed mitigation actions include conservation and enhancement of forest carbon stocks and sustainable management of forests.
    • REDD is a set of steps designed to use market/financial incentives in order to reduce the emissions of greenhouse gases from deforestation and forest degradation. Its original objective is to reduce GHGs but it can deliver ‘co-benefits’ such as biodiversity conservation and poverty alleviation
    • REDD+ calls for activities with serious implication directed towards the local communities, indigenous people and forests which relate to reducing emission from deforestation and forest degradation. It goes beyond deforestation and forest degradation and includes the role of conservation, sustainable management of forests and enhancement of forest carbon stocks
  • A Cancun Adaptation Framework has been proposed to strengthen and address implementation of action, and various kinds of assessments, apart from R&D and host of other issues.
  • Green Climate Fund The fund will be designed by a transitional committee, with 15 members from the developed countries and 25 from the developing nations.
  • Pledge by the developed countries to provide $100 bn annually till 2020.

 

Conclusion

  • UNFCCC secretary-general Christian Figueres emphasised that the main achievement of the Cancun meet has been to restore some degree of faith in the multilateral process.
  • The agreements don’t mention any reduction targets.
  • Though the agreements recognize the need to reduce the GHG emissions and curb the increase in global average temperatures below 2 degrees Celsius above pre-industrial levels, in the absence of any firm target, this could be an inadequate and vague provision
  • Bolivia has rejected the agreement, saying that it won’t support agreement without binding emission cuts.
  • In a sense, the summit was both a major step forward as well as a failure
  • It was a step forward because in recent years climate change negotiations had stumbled and this meeting helped overcome that
  • It was a failure because it failed to reach an agreement for binding restrictions that are required to avert global warming.
  • There was no agreement on how to extend the Kyoto Protocol, or how the $100 billion a year for the Green Climate Fund will be raised or whether developing countries should have binding emissions reductions.

Under the Cancun Agreements, the targets set by industrialised countries for reduction of greenhouse gas emissions are recognised as part of the multilateral process. They must now draw up low-carbon development plans and strategies and also report their inventories annually. In the case of developing countries, actions for emissions reduction will be recognised officially; a registry will record and match their mitigation actions to finance and technology support from rich countries; and they will report their progress every two years. These form a good preamble for target-setting for all member-countries under an agreed framework at Durban next year.

Trivia

  • A large amount of energy used during the conference came from renewable sources
  • Around 10000 trees and bushes will be planted in Cancun

Role of India and its relevance

  • India can act as a mediator between the developing and developed countries
  • India’s approach to climate change negotiations has been governed by three factors – how to protect the country’s economic interest and environment agenda, to use climate change as a tool of global diplomacy and consolidate its position on world forums.
  • At Cancun, India was responsible for having made five insertions into the Agreement
    • In the section on shared vision, the figure of 50 pc has been dropped from identifying a global goal for substantially reducing emissions by 2050
    • The phrase access to sustainable development has been introduced in the context of working towards identifying a time-frame for global peaking of greenhouse gas emissions based on the best available scientific knowledge
    • International Consultation and Analysis (ICA) finds mention the agreements. It proposes to enhance the reporting for the non-Annex 1 parties or developing countries on mitigation  action and its effects and support received
  • At Cancun, India also proposed legally binding emission cuts.

 

 

ECOLOGY- An Introduction

 

 

Ecology is  defined “as a scientific study of the relationship of the living organisms with each other and with their environment.”

The classical texts of the Vedic period such as the Vedas, the Samhitas, the Brahmanas and the Aranyakas-Upanishads contain many references to ecological concepts .The Indian treatise on medicine, the Caraka- Samhita and the surgical text Susruta-Samhita. contain classification of animals on the basis of habit and habitat, land in terms of nature of soil, climate and vegetation; and description of plants typical to various localities.

Caraka- Samhita contains information where air, land, water and seasons were indispensable  for life and that polluted air and water were injurious for health.

The environment is defined as ‘the sum total of living, non-living components;  influences and events, surrounding an organism.

Components of Environment

  1. Abiotic – Energy, Radiation, TEMP, Water, etc.
  2. Biotic- plants, animals, man, DECOMPOSER ETC.

Diesel engine exhaust fumes can cause cancer, humans” and it belong to the same potentially deadly category as asbestos, arsenic and ‘mustard gases.

Six main levels of organisation of ecology are:

  1. Individual- Organism is an individual living being that has the ability to act or function independently.
  2. Population-Population is a group of organisms usually of the same species,

occupying a defined area during a specific time,

  1. Community- Communities in most instances are named after the dominant plant form

(species). A community is not fixed or rigid; communities may be large or small.

Types of Community-

On the basis of size and degree of relative independence communities may be divided into two types-

(a)  Major Community

These are large-sized, well organized and relatively independent. They depend

only on the sun’s energy from outside and are independent of the inputs and

outputs from adjacent communities.

E.g: tropical ever green forest in the North-East

 

(b) Minor Communities

These are dependent on neighbouring communities and are often called societies.

They are secondary aggregations within a major community and are not therefore completely independent units as far as energy and nutrient dynamics are concerned.

e.g: A mat of lichen on a cow dung pad.

The environmental factors determine the characteristic of the community as well as the pattern of organisation of the members in the community

The characteristic pattern of the community is  termed as structure which is reflected in the roles played by various population, their range, the  type of area they inhabit, the diversity of species in the community and the spectrum of interactions between them

Eco-System-An ecosystem is defined as a structural and functional unit of biosphere consisting of community of living beings and the physical environment, both interacting and exchanging materials between them. It includes plants, trees, animals, fish, birds, micro-organisms, water, soil, and  people.

When an ecosystem is healthy (i.e. sustainable) it means that all the elements live in balance and are  capable of reproducing themselves

   TERRESTRIAL ECOSYSTEMS

 

 

The interrelations between organisms and environment on the land constitute “Terrestrial Ecology”.

The most important limiting factors of the terrestrial ecosystems are moisture and temperature.

 

 

TUNDRA

The word tundra means a “barren land” since they are found where environmental conditions are very severe. There are two types of tundra- arctic and alpine.

Distribution:

Arctic tundra extends as a continuous belt below the polar ice cap and above the tree line in the northern hemisphere. It occupies the northern fringe of Canada, Alaska, European Russia, Siberia and island group of Arctic Ocean.

On the south pole, tundra is very small since most of it is covered by ocean .

Alpine tundra occurs at high mountains above the tree line. Since mountains are found at all latitudes therefore alpine tundra shows day and night temperature variations.

Flora and fauna:

Typical vegetation of arctic tundra is cotton grass, sedges, dwarf heath, willows, birches and lichens.

Animals of tundra are reindeer, musk ox, arctic hare, caribous, lemmings and squirrel.

They are protected from chillness by the presence of thick cuticle and epidermal hair.

Mammals of the tundra region have large body size and small tail and ear to avoid the loss of heat from the surface.

The body is covered with fur for insulation.

ENVIRONMENT POLLUTION 2

E — WASTE

E-waste is not hazardous if it is stocked in safe storage or recycled by scientific methods or transported from one place to the other in parts or in totality in the formal sector. The e-waste can be considered hazardous if recycled by primitive methods

Survey was carried out by the Central Pollution Control Board (CPCB) during 2005

In India, among top ten cities; Mumbai ranks first in generating e-waste followed by Delhi, Bangalore, Chennai, Kolkata, Ahmadabad, Hyderabad, Pune, Surat and Nagpur.

 

SOLID WASTE

the discarded (abandoned or considered waste-like) materials

does not include solid or dissolved materials in domestic sewage, or

solid or dissolved materials in irrigation return flows or industrial discharges0

Conventional plastics have been associated with reproductive problems in both humans and wildlife.

Dioxin (highly carcinogenic and toxic) by-product of the manufacturing process is one of the chemicals believed to be passed on through breast milk to the nursing infant.

Burning of plastics, especially PVC releases this dioxin and also furan into the  atmosphere.

Pyrolysis-It is a process of combustion in absence of oxygen or the material burnt under controlled atmosphere of oxygen. It is an alternative to incineration. The gas and liquid thus obtained can be used as fuels.

 

Waste Minimization Circles (WMC)

helps Small and Medium Industrial Clusters in waste minimization in their industrial plants.  assisted by the World Bank with the Ministry of Environment and Forests acting   as the nodal ministry.  being implemented with the assistance of National   Productivity Council (NPC), New Delhi.

aims to realise the objectives of the Policy Statement for Abatement of Pollution (1992), which states that the government should educate citizens about environmental risks, the economic and health dangers of resource degradation and the real economic cost of natural resources.

BIOREMEDIATION

the use of microorganisms (bacteria and fungi) to degrade the environmental contaminants into less toxic forms.

Phytoremediation

is use of plants to remove contaminants from soil and water .

Rhizofiltration

  • a water remediation technique that involves the uptake of contaminants by plant roots.
  • used to reduce contamination in natural wetlands and estuary areas.

 

ENVIRONMENTAL IMPACT ASSESSMENT

Notification on Environmental Impact Assessment (EIA) of developmental

projects 1994 under the provisions of Environment (Protection) Act, 1986 making EIA  mandatory for 29 categories of developmental projects. One more item was added to the list in January, 2000. environmental impact assessment statutory for 30 activities

Environment Impact Assessment Notification of 2006 has categorized the developmental projects  in two categories, i.e., Category A and Category B

Ministry of Environment & Forests

‘Category A’ projects are appraised at national level by expert appraisal committee

India has constituted the State Level Environment Impact Assessment Authority (SEIAA) and State Level Expert Appraisal Committee (SEAC)  to decentralize the environmental clearance process

The objective of EIA is to foresee and address potential environmental problems/  concerns at an early stage of project planning and design.

 

 

The EIA notification establishes four stages for obtaining Environmental Clearance.

  1. Screening
  2. Scoping and consideration of alternatives Baseline data collection
  3. Impact prediction
  4. Assessment of alternatives, delineation of mitigation measures and environmental impact statement
  5. Public hearing
  6. Environment Management Plan Decision making
  7. Monitoring the clearance conditions

Screening- It is only for Categories B

Screening Criteria are based upon:

  • Scales of investment; •       Type of development; and, •      Location of development

B1 Categories project require Environmental Impact Assessment while B2 category projects are exempted from EIA.

State Level Expert Appraisal Committee determine about project categories

Climate Change

 

  • It is the long term change in the statistical distribution of weather patterns over periods of time
  • Though it has been happening naturally for millions of years, in recent years it has accelerated due to anthropogenic causes and has been causing global warming.
  • UNFCCC defines climate change as – “a change of climate which is attributed directly or indirectly to human activitythat alters the composition of the global atmosphere and which is in addition to natural climate variability observed over comparable time periods”

NORTH-EASTERN STATES

  • Manipur wants fishermen to stop using LED bulbs

 

  • The state forest and environment ministry has warned that stern action will be taken against fishermen who used light emitting diode (LED) bulbs at Loktak Lake by night. While the government has conceded that fishing is the prime livelihood for people living around the lake and the activity cannot be stopped, it has said the use of these bulbs disturbs the habitat of the several migratory birds who flock there.
  • Thousands of migratory birds, mostly water fowls belonging to around sixty different species, are currently staying at the 237 sq km lake, the largest freshwater lake in the northeast. 

    INTERNATIONAL

     

    • WEF launches Global Centre for Cybersecurity
    • In a bid to safeguard the world from hackers and growing data breaches — especially from nation-states — the World Economic Forum (WEF) announced a new Global Centre for Cybersecurity.
    • Headquartered in Geneva, the centre will become operational from March.

     

    • Cyber breaches recorded by businesses are on the rise. In the last five years, these have almost doubled to an average of 130 breaches per business in 2017.

     

    • As a borderless problem, urgent action is needed to create a safe operating environment for new technologies like Artificial Intelligence, robotics, drones, self-driving cars and the Internet of Things (IoT).

     

    • The global centre will be an excellent opportunity to safeguard verticals like automotive and health care where wireless connectivity is the key.

     

    ·        First India-designed vaccine passes WHO test

     

    • For the first time, a vaccine conceived and developed from scratch in India has been “pre-qualified” by the World Health Organisation.
    • The Rotavac vaccine, developed by the Hyderabad-based Bharat Biotech Limited last year, was included in India’s national immunisation programme. To be “pre-qualified” means that the vaccine can be sold internationally to several countries in Africa and South America.
    • While several vaccines from India have been pre-qualified, this is the first that was entirely developed locally and, according to experts, is a sign that there is a credible industrial, scientific and regulatory process in place to develop vaccines in India.
    • The Rotavac vaccine protects against childhood diarrhoea caused by the rotavirus and was built on strain of the virus isolated at the the All India Institute of Medical Sciences here over 30 years ago.
    • India included the Rotavac in its national immunisation in 2016, with about 35 million doses delivered till date. A dose costs between ₹55-60, according to the company.
    • Rotavirus is responsible for an estimated 36% of hospitalisations for childhood diarrhoea around the world and for an estimated 200,000 deaths in low- and middle-income countries.

     

    NATIONAL

     

    • AICTE releases new model curriculum
    • The All-India Council for Technical Education (AICTE) formally released its new model curriculum for engineering and technical courses reducing the credits to be earned for an undergraduate degree from 220 to 160.
    • The time freed would be utilised for practical and creative activities, including hackathons.
    • The top technical education regulator had also decided to make internships mandatory for the award of degrees, as part of the exercise.
    • The internship would have a minimum of 14 credits. Each credit means 40-45 hours of work.

     

    • Multiple chief guests, a first for Republic Day
    • From a single leader gracing Republic Day, India has pulled off a diplomatic coup of sorts by having as many as 10 leaders from the Association of Southeast Asian Nations (ASEAN), for January 26 this year.
    • Just as the presence of U.S. President Barack Obama as the chief guest at Republic Day in 2015 sent a signal to the rest of the world, the ASEAN leaders’ participation has a resonance of its own.
    • An important aspect of the R-Day parade this year is the focus on showcasing indigenously developed military platforms for the visiting heads of state. This is significant as India is now trying to significantly beef up its military sales as part of its defence diplomacy and wants to showcase these platforms to ASEAN countries.
    • List of Padma awardees 2018
    • This year 85 recipients have been selected for the prestigious awards including two duo cases. This includes 3 Padma Vibhushan, 9 Padma Bhushan and 73 Padma Shri awards. Fourteen of the awardees are women, while 16 persons are foreigners and three are being awarded posthumous.

    • Padma Awards were instituted in the year 1954. Except for brief interruptions during the years 1977 to 1980 and 1993 to 1997, these awards have been announced every year on Republic Day. The award is given in three categories, viz. Padma Vibhushan, Padma Bhushan and Padma Shri, in the decreasing order of importance.

     

    • Padma Vibhushan for “exceptional and distinguished service”. Padma Vibhushan is second highest civilian award in India.

     

    • Padma Bhushan for “distinguished service of a high order”. Padma Bhushan is third highest civilian award in India .

     

    • Padma Shri is awarded for “distinguished service”. Padma Shri is last and fourth highest civilian award in India.

     

    • The Padma award is just an honour. No cash allowance or any facility/benefit in terms of concession etc.

     

    • The Padma Awards are given on the recommendations done by the Padma Awards Committee, which is created by the Prime Minister Annually.

     

    • The award Committee is supervised by the Cabinet Secretary and comprises of Secretary to the President, Home Secretary, and 4-6 distinguished individuals as members.

     

    • The awardees are given a medallion and a Sanad signed by the President of India.

     

    • The total number of awards to be given in a year should not be more than 120 (not including posthumous awards and to foreigners/ NRI/OCIs).

     

    • No Padma awards were given in the year of 1978, 1979, 1993, 1994, 1995, 1996 and 1997 due to the change of government.

    • The airports to be connected under phase-II: Total 78 airports i.e. 36 served airports, 13 underserved airports and 29 unserved airports.

FUNCTIONS OF MANAGEMENT – STAFFING    

 

Staffing refers to the managerial function of employing and developing human resources for carrying out the various managerial and non-managerial activities in an organisation. This involves determining the manpower requirement, and the methods of recruiting, selecting, training and developing the people for various positions created in the organisation.

 

Staffing function is an integral part of human resource management and, in its wider sense, also includes the activities of determining the remuneration of workers, appraising their performance, and deciding on their promotion, transfers, etc.

 

The process of staffing starts with ascertaining the required number of various categories of employees for the organisation. This is known as manpower planning. It decides the kinds of staff and the number of staff required for the organisation. This is done through several methods like job analysis, workload analysis, etc. The next thing to be done in the staffing process is the recruitment exercise, i.e., finding out the available manpower from internal and external sources. The next step is to select the right person from the available manpower through tests and interviews and make appointments. This is followed by their placement on the jobs and necessary introduction of the work environment and the rules of compensation, promotion, transfer etc. Thus, the various steps involved in the process of staffing are as follows.

 

  • Manpower Planning: Manpower planning refers to the process of estimating the manpower requirement of an organisation. While estimating the manpower requirement, the management generally keeps in mind the available infrastructure including the technology, production schedule, market fluctuation, demand forecasts, government’s policies and so on. It tentatively decides the kinds of staff as well as the number of staff needed for the organisation. The focus of the manpower planning is to get right number of qualified people at the right time.

 

  • Job Analysis:. It is a pre-requisite for any recruitment exercise. The job analysis helps in determining the qualifications, skills and experience required for various categories of employees. It involves:

(i)Job Description: Identification of each job in terms of duties and responsibilities.

 

(ii) Job Specification: Determining the abilities and skills that are required for performing the job.

These two aspects of job analysis (job description and job specification) are useful in recruitment and selection of employees so as to find the right person for the job.

 

  • Recruitment: The process of finding and attracting suitable applicants for employment for various activities of the organisation using the internal as well as the external sources.

 

  • Internal Sources: In any business, existing employees expect that they will have chances of promotion and will be considered for higher positions before outsiders are considered. Managers therefore may promote and transfer some of the existing employees to fill the vacant positions. The advantage of internal recruitment is that it is easier for managers to fill vacancies as they are conversant with the abilities and skills of their subordinates and have records of their performances. Employees also feel happy as their work performance is recognised by management through promotion. However, there is one major drawback of recruitment through internal sources i.e., the organisation is deprived of the benefit of inducting fresh blood into its system.

 

  • External Sources: All vacancies cannot be filled up from within the organisation. Existing employees may lack the required skill, initiative and qualification needed for the jobs involved. Hence managers have to recruit some persons from outside the organisation. Not only that the external recruitment provides a wide choice from among a large number of external candidates from which employees may be recruited. The workers and office employees at the lower level are often recruited from outside the organisation. The various external sources of recruitment are as follows:

 

(a)Media Advertisements: You must have seen advertisements in newspapers about vacancies in organisations. The advertisement contains details about the job, its nature, the qualification required to do the job, how to apply, etc.This is a very popular medium of advertising. The job advertisements are also given in magazines, specialised employment magazines like Employment News, RozgarSamachar, etc. Now-a-days we also commonly find such advertisements in various electronic media like television and Internet. Such advertisements normally get a very good response from the prospective candidates.

 

(b)Employment Exchanges: In India, employment exchanges have been setup by the government for bringing together job-seekers and employers who are looking for employees. Those who are in search of employment get themselves registered with the local Employment Exchanges which keep a record of all such persons in detail who require help in finding jobs. The employer informs about the vacancies to the nearest Employment Exchange. The Employment Exchange, in turn, identifies the names of the qualified employment seekers already registered with it, and forwards them to the employer for consideration. Thus, if you are seeking a job after passing the senior secondary examination, it would be better if you get yourself registered with an Employment Exchange. It may forward your name to the prospective employers keeping in view the suitability of the job as per your qualifications.

 

(c)Educational Institutions: Now-a-days, companies/big organisations maintain a close liaison with the universities, vocational institutes and management institute for recruitment of their staff. As and when the need arises, the companies send one or more of their senior executives to the institutions of repute imparting such professional/technical education to students. These executives take the interview of the interested candidates and select the suitable candidates as per their requirement. This process is popularly known as campus interview and is found to be an effective source of recruitment of managers, engineers, technicians etc. for many companies on a regular basis.

 

(d)Unsolicited Application : Those looking for jobs often apply on their own initiative. They assume that certain vacancies are likely to arise, and apply without references to any job advertisement. Managers keep record ofsuch applications and contact the suitable candidates when they need them.

 

(e)Recruitment at the Factory gate : This is found mainly in case of factory workers to be recruited on daily wages. Such workers gather in the morning at the factory gate to serve as casual workers. Very often existing regular employees go on leave, and their vacancies are filled up by recruitment at the factory gate. These casual workers having served in the factory for sometime may be considered for regular employment at some stage.

 

(f)Referrals: Quite often the management gets references about interested workers from different sources like workers unions, previous employees, existing employees, clients of the organisation etc. These sources are important because their recommendations are made by people who are associated with the organisation and are fully conversant with its requirements. Sometimes we also receive recommendations from our friends and relatives to employ persons known to them. But one should be very much cautious while considering such recommendations.

 

(g)Private Employment Agencies: In urban areas, a number of private organisations have started functioning as employment agencies. These agencies register with them the names of the individuals who are seeking employment and try to arrange job interviews for such candidates. Companies often getting touch with such agencies to provide them the details of suitable candidates for various jobs.

 

 

  • Selection: Selection refers to the process of choosing the most suitable person from among the list of interested candidates. It involves going through the qualification and experience of all candidates and matching them with the expectation for the job so as to decide on the most suitable ones for the job. The entire process goes through a number of steps which may be called as selection procedure. Selection Procedures stated above, the selection procedure consists of a number of steps in logical order to identify the candidates who are to be finally appointed. These steps are :

 

  • Screening the Applications: After receiving the applications from the candidates through recruitment process, the same must be examined to decide which ones deserve to be considered and followed up. Screening is usually done by a senior officer of the company or by a screening committee. The purpose of screening is to prepare a list of eligible candidates who are to be evaluated further. Candidates not eligible are thereby excluded from further consideration

 

  • Holding Tests: After screening the applications, eligible candidates are asked to appear for selection tests. These tests are made to discover and measure the skill and abilities of the candidates in terms of the requirements of the job. The nature of test depends upon the nature of the job involved

 

  • Selection Interview: Interview is the most important part of the selection procedure. It serves as a means of checking the information given in the application form and making an overall assessment of the candidate’s suitability for the job.

In an interview, the candidate has a face-to-face interaction with the employer or representatives of the employer, where they try to judge the ability of the candidates. They also get an opportunity to go into the details of the candidate’s background which helps a lot in assessing the candidate’s suitability.

 

  • Checking of References: In addition to the requisite educational qualification, skill and experience, it is expected that the candidates who are to be considered for employment must have other qualities like balanced temperament, honesty, loyalty, etc. These qualities cannot be judged on the basis of any test. Therefore, information is obtained and verified from the heads of educational institutions where the candidates have studied, or from the persons whose names are given by the candidates as referee, or from their previous employers.

 

  • Medical Examination: Candidates finally selected for the job are asked to undergo medical examination to see whether the selected candidates are physically fit for the job. A proper medical examination ensures higher standard of health of the employees and their physical fitness which, in turn, reduces the labour turnover, absenteeism and accidents.

 

  • Issue of Appointment Letter: Candidates finally selected are offered to join the organisation for which a formal appointment letter is issued containing the nature of job, the remuneration, pay scale, and other terms and conditions relating to employment. Usually a reasonable time is given to the candidates to join the organisation.

 

 

 

 

 

  • Induction: Induction is the process of introducing new employees to the organisation. The new employees should know under whom and with whom he/she is to work, get acquainted and adjusted to the work environment, get a general idea about the rules and regulations, working conditions etc. Usually the immediate supervisor of the new employee introduces him to his work environment. A proper induction programme is likely to reduce his anxiety on how to cope with the work and how to become part of the organisation and helps in development of a favourable attitude towards the organisation and the job.

 

  • Training and Development: the employees to improve their knowledge and skill so as to be able to perform their tasks more efficiently is known as training. It is an organised activity for increasing the knowledge and skills of people for a specific purpose. The term ‘development ‘refers to the process of not only building up the skill and abilities for specific purpose but also the overall competence of employees to undertake more difficult and challenging tasks. It is generally used with reference to the training of managers and executives. Training and Development Training is an act of increasing the knowledge and technical skills of an employee for doing a particular job efficiently.

 

Development refers to the learning opportunities designed to help employees to grow. It involves growth an individual in all areas. Development help workforce to improve technical skills, problem solving skills and decision making skills. Training is necessary for new employees as well as the existing employees for improving their performance at work. For new employees, training is necessary to help them get acquainted with the method of operation and skill requirement of the job. For existing employees, training at periodical intervals is helpful for learning better ways of doing the work, and also as and when they have to undertake new jobs. Thus, training helps employees to improve their knowledge and skill and make them perform their tasks more efficiently. It also helps them in promotion and improves their attitudes and confidence levels.

 

Importance of Training and Development Benefits of training for organisations:

 

Methods of Training There are different methods of giving training to the employees which can be divided into two broad categories.

 

On-the-Job methods and Off-the-Job methods.

 

  1. On-the-Job methods : In these methods, the employees learn about their jobs while doing the work duly assisted by their supervisors or seniors. These methods encourage self-learning through practice. Job instruction or coaching, and job rotation, learning while working as an assistant to a senior, understudy positions, temporary promotions are some of the common methods of on-the-job training.

 

  1. Off-the-Job methods: These methods involve training employees away from the work place so that experts may conduct the training and employees are free from immediate pressure of completing the jobs at hand. Lectures with demonstration, conferences, case discussions, video shows and films are some of the common methods used as off-the-job training methods. Then, there is another off the job method of training called vestibule training. The vestibule training refers to the training in specially designed workshops in which an attempt is made to duplicate as closely as possible the actual conditions of the work place. In such workshops a large number of employees can be trained in a relatively short period of time.

 

 

  • Performance Appraisal: Performance appraisal means judging the performance of employees. Specifically, it means judging the relative abilities of employees at work in a systematic manner. This enables managers to identify employees who are performing the assigned work satisfactorily, and those who are not able to do so, and why. To be fair, performance appraisal needs to be carried out using the same methods and keeping in view uniform standards of work. Generally it is the responsibility of supervisors to carry outperformance appraisal of their subordinates, and report it to their own superiors.

 

The standard of performance or the expected level of performance of an employee on a job forms the basis of judging how well the employee has performed, and whether one employee is more efficient than the other in doing a similar job. The yardstick placed may be the desired quantity of output, the quality of work done, minimisation of wastage of materials caused in the process of work etc. The choice depends upon the type of job involved. However, where quantity or number of units produced or wastage of materials form the basis of appraisal, it is likely to be more accurate. On the other hand, quality of work done may be difficult to measure and hence performance appraisal may not be very accurate.

 

 

 

 

 

 

 

 

Some Important things in staffing

 

What is Probation Period?

 

In most of the organisations the candidates are not initially appointed on permanent basis because it is considered better to try them for a few months on the job itself. This period of service is known as the period of probation. It is necessary because no procedure of selection can fully establish the qualities of a selected candidate. It is only by observing a person at work that one can find out how he performs and also how he behaves with his superior and fellow employees. If during the probation period, his performances not found satisfactory, his period of probation may be extended. The management may also transfer him to some other job at which he may be expected to do better.

 

What is Difference between recruitment and selection:-

 

Recruitment and selection are the two essential components of the staffing process. While the recruitment helps in attracting suitable candidates, selection helps in finding out the candidates who meet the requirements of the job. These are closely inter-connected activities. However, recruitment and selection differ in certain respects. While the recruitment refers to the process of attracting good applicants for jobs, selection identifies the most suitable amongst the applicants. In the recruitment process, the effort is to attract the candidates as many as possible and it is regarded as a positive process. But, selection is a negative process as it involves rejection of many candidates. Recruitment involves decisions as regard to the sources of potential candidates. Selection is made through different steps in the procedure adopted. Recruitment helps the manager to attract good candidates

NORTH-EASTERN STATES

  • Arunachali yak the first to be registered as new breed

 

  • Yaks, found in the mountainous regions of Arunachal Pradesh, have been registered by the Karnal-based National Bureau of Animal Genetics Resources (NBAGR) as a distinct breed known as Arunachali yak, this being the first instance of such a registration in the country. Union agriculture minister Radha Mohan Singh will formally award the recognition in New Delhi on Wednesday to the representatives of National Research Centre on Yak (NRCY) based at Dirang in Arunachal Pradesh.

 

  • The study found that Arunachali yaks are characterized by their predominantly black body colour and the high fat content in their milk which sometimes goes up to 7.45%. A lactating Arunachali yak produces, on an average, 1.3 kg milk per day. Though the milk is comparatively of poor quantity, it is compensated by the high fat content which makes it useful to produce different milk products.

 

  • However, scientific interventions, especially in the areas of breeding and rearing, have been able to slow down the decline of population as Arunachali yaks still remain the main source of livelihood for many Brokpas (yak rearers). West Kameng and Tawang are mainly dominated by the Monpa community, which treats the yaks as an asset for the rural economy, and rears these animals in organized farms or semi-migratory systems.

  • Dust mitigation plan must for firms

 

  • The Environment Ministry has made it mandatory for companies seeking environment clearance to ensure that they put in place a dust mitigation plan.

 

  • The requirements, specified in a gazette notification on January 25, say that roads leading to or at construction sites must be paved and black-topped. There could be no soil excavation without adequate dust mitigation measures in place. No loose soil, sand, construction waste could be left uncovered. A water sprinkling system was mandatory, and the measures taken should be prominently displayed at the construction site. Moreover, the grinding and cutting of building materials in open area were prohibited and no uncovered vehicles carrying construction material and waste would be permitted.

 

  • The standards were developed by the Central Pollution Control Board as part of the National Ambient Air Quality Standards (NAAQS), and will now empower the organisation to fine companies and agencies for not complying with norms.

 

  • Road dust contributed 56% of all PM10 pollution, while it was 38% for PM2.5.

 

  • Before PM2.5 became the focus of attention — for its role in lodging itself in the lungs and for being a key component of diesel emissions — dust was the key villain for a long time. Dust is a generic term for a vast mix of metals and non-metals — silicon, aluminium, titanium, manganese, copper, barium, antimony, selenium and zinc.

 

Gk bit  – PM (particulate matter)

 

  • PM stands for particulate matter (also called particle pollution): the term for a mixture of solid particles and liquid droplets found in the air. Some particles, such as dust, dirt, soot, or smoke, are large or dark enough to be seen with the naked eye. Others are so small they can only be detected using an electron microscope.

 

Particle pollution includes:

 

 

  • PM10 : inhalable particles, with diameters that are generally 10 micrometers and smaller; and

 

  • 5: fine inhalable particles, with diameters that are generally 2.5 micrometers and smaller.

 

 

  • The average human hair is about 70 micrometers in diameter – making it 30 times larger than the largest fine particle.
