Minerals in Meghalaya

Meghalaya is endowed with sizeable deposits of a number of valuable minerals. Coal, limestone, uranium, granite, kaolin, clay and glass sand are the principal minerals. A brief account of mineral resources is as follows:

Limestone

An extensive bed of limestone occurs in the Southern part of the State from Jaintia Hills in the East and Garo Hills in the West. The main deposits are found around Cherrapunjee, Mawlong, Ichamati, Shella, Komorrah in the East Khasi Hills district; Borsora and Bagli in the West Khasi Hills district; Lakadong, Lumshnong and Nongkhlieh in the Jaintia Hills district; and Darrang Era-aning, Siju, Chokpot in the South Garo Hills district.

Coal

Most of the coal reserves in Meghalaya are tertiary reserves.Coal occurs in Mikir Hills, Khasi Hills, Jaintia Hills and Garo Hills districts. The production of upgraded coal was reported by private non-captive mines in the unorganised sector located in these areas except Mikir Hills district. The mines are operated mostly by the local tribals in their private lands.

Uranium reserves in Meghalaya

Meghalaya is the third uranium rich state in the country after Jharkhand and Andhra Pradesh. The state accounts for 16 per cent of Indias uranium reserves, with deposits estimated to be around 9,500 tones and 4,000 tones respectively at Domiasiat and Wakhyn, both in West Khasi hills region. Minerals in Meghalaya

Kyelleng-Pyndengsohiong, Mawthabah (KPM) uranium mining project is located in the West Khasi Hills district of Meghalaya state in the North East region of India. Formerly this project was also known as Domiasiat uranium mining project. The Atomic Mineral Directorate for Exploration and Research in 1972 found evidences of uranium deposits in the area which was confirmed by 1996 after intensive drilling between 1992 and 1996. Uranium Corporation of India Limited (UCIL) proposes to mine it using open pit mining method up to a depth of 45 m. The processing plant will be constructed at Mawthabah. It is estimated that KPM deposit in Meghalaya will last for 25 years.

Clay

Clay of various types such as Kaolin (China clay), white clay, and fire clay are found in various parts of the states. These clay are suitable for the ceramic, paper, rubber and refractory industries. It has been estimated that there are a few hundred million tonnes of clay reserved in the state.

Granite reserves

Deposits of multi-coloured granite have been located around nongpoh in the Ri-Bhoi district, mylliem in the east khasi hills district; mawkyrwat and nongstoin in the west khasi hills distric.

Sand deposits

The sand deposits of the State are mainly concentrated in Khasi hills. The glass deposits of Laitryn grew coal field and around Shillong are found to be suitable for manufacturing of ordinary bottle glasrs, window glass etc. and with some chemical pu rification even for sheet glass and flint glass. Some of the sands are within the specifica tion o f foundry sands, which are now in great demand in the country. The estimated reserve of glass deposits is about 2.30 m illion tonnes as against Tripura – 0.18 m illion tones.

Feldspar and quartz occur near Tura in Garo hills and near Hahim in Khasi Hills. The estimated mining reserve of feldspar in the State (0.02 million tonnes) is at par with Assam (0.02 million tonne),2 3456 while the quartz is 2.03 m illion tonnes as compared to Tripura – 0.19 million tonnes.

Massive sillimanite associated with corrundum occurs in Khasi hills . More than 2i deposits have been located in the vicinity of Sonapahar, Nongpur and Nongbain villages and are worked by the Assam Sillimanite Ltd. Most of the deposits contain sillimanite with admixed corrundum to a little extent, one or two entirely of corrundum and several of sillimanite only.

Rivers and drainage system of Meghalaya

One of the world’s wettest regions is found in Meghalaya. Mawsynram and Cherrapunji (Sohra) in the East Khasi Hills district are geographically considered as the rainiest places in the World. — Cherrapunji, which has an average annual precipitation of about 11,430 mm (450 inches) during monsoon season (from May to September) and Mawsynram, a village directly west of Cherrapunji, where rainfall of around 17,800 mm (700 inches) per year has been recorded. The area receives rainfall on an average for 160 days in a year, spread over 6 to 8 months from March to October.

Physiographically, Meghalaya represents a remanant of an ancient plateau of Pre-Cambrian Peninsular shield, block lifted to its present height and is referred as Meghalaya Plateau or as Shillong-Mikir massif. It is the detached northeastern extension of Indian Peninsular shield, part of which lies beneath the alluvium deposited by Ganga Brahmaputra system of rivers. The rivers of the State are rainfed and therefore their discharge dwindles during summer. Important rivers in Garo Hills region are Daring, Sanda, Bugi, Dareng and Simsang. In the central and eastern part of the plateau are Umkhri, Digaru, Umngot and Myntdu rivers.

The surface water resource is tapped in a number of places by constructing dams across the rivers. The reservoirs, like the Umium and Kopili, so developed are not only used for irrigation and drinking water but also for generating electricity. Inspite of this, the area experiences shortage of water during the summer resulting in crisis for drinking water. This is mainly due to topographical and geomorphological conditions apart from alterations of the natural land surface by way of development, mining and urbanization.

Moreover, the characteristic hilly and steep sloping terrain condition in the area with localized small valleys results in very high surface run-off during the monsoon.

Some of the important rivers of Meghalaya are as follows:

Digaru

Digaru is a river originating in the Garo-Khasi hills of Meghalaya state in India, flowing towards the northeast and then meeting the Kolong river and then merging with the Brahmaputra river. The name Digaru originated from a Kachari/Mech word ‘Di’ which means water and ‘Garo’ means the people living in the Garo hills. Hence Digaru literally means “water of the Garo”.

Kopili River

The Kopili originates in the Meghalaya plateau and flows through southern Assam before its confluence with the Brahmaputra. In Assam it drains the districts of Karbi Anglong, Dima Hasao, Kamrup and Rivers and drainage system of Meghalaya Nagaon. The river flows for a total length of 290 kilometres (180 mi) and has a catchment area of 16,420 square kilometres (6,340 sq mi). It is noted for several spectacular waterfalls along its course which has several deep gorges and rapids in the 120 kilometres (75 mi) of its flow before debouching into the plains at Nagaon district.

Myntdu River

Myntdu River is one of the major water bodies in Jaintia Hills District, Meghalaya, locally known as ‘ka Tawiar ka Takan’ (Our Guardian Angel) in the Pnar dialect. It is a blessing to the residents of the town of Jowai and adjacent places. Its abundant water is used to irrigate the Myntdu Valley, located on the outskirts of Jowai town. The river, originating at 1,420 metres (4,660 ft) above sea level, is fit for hydro-power development.

The river flows across Jowai, and then through Leshka (where a Hydro Project Dam is being constructed) to reach a village Borghat, within Jaintia Hills, before finally entering Bangladesh, where it is locally called ‘Shari’.

Piyain River

Piyain River a trans-boundary river of India and Bangladesh. It is a tributary of the Surma river, which is originates from the Umgat river of Assam. The river enters Bangladesh through Sylhet district. The length of the river is 145 km. Piyain river has emerged from the river om or Umagat river or Assam.

Someshwari River

Someshwari River, known as Simsang River in the Indian state of Meghalaya, is a major river in the Garo Hills of Meghalaya and Netrakona District of Bangladesh. It divides the Garo Hills into two parts.

Irrigation and hydro power of Meghalaya

Bamboo irrigation in Meghalaya

In Meghalaya (one of the seven northeastern states in India), an ingenious system of tapping of stream and springwater by using bamboo pipes to irrigate plantations is widely prevalent. It is so perfected that about 18-20 litres of water entering the bamboo pipe system per minute gets transported over several hundred metres and finally gets reduced to 20-80 drops per minute at the site of the plant. The tribal farmers of Khasi and Jaintia hills use the 200-year-old system. Irrigation and hydro power of Meghalaya

Dating back 200 years, tribes in Meghalaya have used bamboo drip irrigation as a means of bringing water to seasonal crops. This traditional technology uses locally available material while harnessing the forces of gravity. Holed bamboo shoots are placed downhill, diverting the natural flow of streams and springs across terraced cropland. The advantages of using bamboo are such that it prevents leakage, increases crop yield with less water, and makes use of natural, local, and inexpensive material.

The Jaintia, Khasi, and Garo hills of Meghalaya are largely made up of steep slopes and generally rocky terrain where the soil has low water retention capacity and where the use of groundwater channels is impossible. During the dry seasons, rain fed crops such as paddy, betel leaf, and black peppers can be irrigated by bamboo drip irrigation.

The bamboo drip irrigation system is normally used to irrigate the betel leaf or black pepper crops planted in arecanut orchards or in mixed orchards. Bamboo pipes are used to divert perennial springs on the hilltops to the lower reaches by gravity. The channel sections, made of bamboo, divert and convey water to the plot site where it is distributed without leakage into branches, again made and laid out with different forms of bamboo pipes. Manipulating the intake pipe positions also controls the flow of water into the lateral pipes. Reduced channel sections and diversion units are used at the last stage of water application. The last channel section enables the water to be dropped near the roots of the plan.

Bench terrace Irrigation practice

This is the common irrigation practice in Meghalaya as well as throughout the North East Himalayan region. The hill streams are tapped as soon as they emerge from the forests and the water is channeled to accommodate a series of terraces. In this system, water flows continuously from the upper to lower terraces. This method of irrigation practice is widely used for non-fertile land to be utilized for raising rice crops. Stone and gunny bags help in the maintenance of terraces and stop soil erosion problems. Submergence of water up to 5 – 8 cm is maintained continuously throughout the year. After harvesting, ear head of rice is plucked and the straw is left as such in the field, which then gets rotted and helps improving soil fertility. Mostly all farm operation is done manually; bullock power is used for field preparations only in some pockets of Meghalaya. Bench terracing is an important conservation measure for valleys and hill slopes. This is used predominantly for rice cultivation. In bench terrace agriculture practice under rainfed condition, topo-sequence crops such as maize, bean and potato are planted on upper slopes and crop requiring more water such as rice and jute are grown on lower slopes. The excess runoff from upper portion of slope is nutrient rich, utilized for the lower hill crops.

Hydro power in Meghalaya

Meghalaya is rich in potential water power resources, hydro power has played an important role in the state’s energy policy.

Small Hydro Power

In a move that aims to address the power requirements of the Megahlaya, as many as 50 mini and micro hydel power projects have been identified to be set up in different districts of the state.

The projects which have already been commissioned include Sonapani on Wahumkhra-Umshyrpi river, Pashyiang Micro HEP on Barim river and Umsaw Micro HEP on Umsaw river. The Lakhroh Micro HEP on Lakhroh river in Jaintia Hills district is under construction.

The Ministry of New and Renewable Energy (MNRE) has also identified 37 mini and micro hydel projects in the state with a cumulative power generation capacity of around 8.5 MW. Out of the total 37 projects, elecven project sites are located in West Garo Hills, South Garo Hills and East Garo Hills districts; nine of them in West Khasi Hills district; eight in East Khasi Hills district; six in the Jaintia Hills district and three in Ri Bhoi district.

Some of the hydro power projects in Meghalaya are as follows:

Myntdu-Leshka Hydro Project

The Myntdu-Leshka Hydro Project Dam (3X42 MW)[2] built across the river, undertaken by MeECL, scheduled in three phases, is located at Leshka, West Jaintia Hills district, Meghalaya near Amlarem, the sub-division headquarters. The project cost is estimated to be around INR 360 crores.

Umiam Hydro Power Complex

All the power stations are in the Umtru River which flows to the north into the mighty Brahmaputra. Running adjacent to this river are two other rivers viz. the Umiam and the Khri. Water from the Umiam basin is diverted into the adjacent Umtru basin thus enhancing the water flow of the Umtru River where all four power stations are constructed. In a similar manner, the water from the Khri River is also intended to be diverted to the existing reservoirs at the Umtru River to further enhance the power generation at the existing system.

Horticulture in Meghalaya

January 15, 2018September 2, 2024 by rawan239

Horticulture in Meghalaya

Meghalaya has three factors conducive for the development of horticulture – vast land suitable for horticulture development, diversity in agro-climatic factors making cultivation of an array of crops feasible and established tradition of horticulture activity making further expansion easy.

A large extent of land is available in the form of fallows, cultivable waste and miscellaneous tree crops. Most of this land is in hill slopes and is more suitable for plantation and fruit crops than traditional agricultural crops. With diversity in elevation, temperature, topography and rainfall a variety of horticultural crops can be grown.

Meghalaya has a long history of growing horticultural crops. Potato, Pineapple, orange, turmeric, ginger and areca nut are grown traditionally and besides these crops, a variety of new crops like tea, cashew and strawberry have been introduced. Most of the land used for these crops is not suitable for traditional agricultural crops like cereals, pulses, oil seeds and fibres. With the introduction of Horticulture in Meghalaya Horticulture Mission for North Eastern & Himalayan States, a lot of area expansion has taken place, but the programme has had little impact on marketing and processing. This can be taken as a potential for future development of the sector.

Strategy

Cluster approach to strengthen the existing concentration of crops. For each crop post harvest management and value chain management will be given emphasis so that additional income and employment will be generated in the State itself.
New technologies in Post-Harvest infrastructure like grading, packaging, ripening chambers will be introduced for the major crops in areas of their concentrations. As it is difficult to attract huge investment to start large scale processing units, small scale and cottage units will be encouraged and support will be provided for them.
Farmers associations (FPOs & FIGs, etc) will be promoted for development of horticulture as a holistic approach.
Convergence with other programmes will be established for optimising the resource use.
Demonstration of new technologies and crop management practices are being taken up with farmers and other stakeholders.

Quality planting material production

As good quality planting material is the backbone of any horticultural economy, this is one of the most important issues to be addressed, especially since there has been tremendous expansion of cultivation (under convergent schemes like the RKVY, BRGF, NREGS in addition to the normal schemes of the Department) and since around 60% of planting material is imported into the State either from nurseries in other States or from outside the country, resulting in increased production costs and draining of valuable foreign exchange. Moreover, the bulk of supply is from small, unregistered nurseries where quality is difficult to enforce.

The State will seek the involvement of the private sector through the establishment of nurseries, which could be registered and affiliated with the NHB and other recognised agencies, so that quality standards are adhered to and a system of surveillance and certification of the operating standards and planting material are put in place.

It is envisged that this will usher in income-earning opportunities for retired Departmental officers and entrepreneurial avenues for fresh unemployed graduates. The Planting Material Production Centres (PMPCs) set up with grants from the 13th Finance Commission, will produce quality planting material for new crops like strawberry, kiwi, raspberry and blackberry as well as for traditonal crops like potato, cashew, citrus (orange and sweet oranges), pineapple, spices (turmeric, ginger, black pepper) and temperate fruits. These PMPCs will be geared to cater not only to the planting material needs of their own clusters, but also to the needs of the other districts of the State as well as other States of the North East. The objective, in the long run, is to turn Meghalaya into a planting material destination for the entire North East.

Area expansion

Model orchards : There are a number of unique fruit crops which are indigenous to the State with tremendous commercial potential, but which have never been properly utilized due to the lack of organized cultivation. The area under many of these crops is declining and some are on the verge of extinction. Keeping in view the need to preserve the horticultural heritage of the State and to provide for the commercial cultivation and exploitation of these crops, there is an imperative need to demonstrate the economic viability of these crops through the establishment of model orchards. In order to make these model orchards successful, for emulation by the farming community, and to ensure their continuity, it is proposed that the orchards be set up within and in conjunction with the integrated farming proposed to be implemented in the micro-watersheds.

Theme villages : The remarkable success achieved in the ‘’Strawberry Village’’ of Sohliya in the Ri Bhoi district will be transferred to different crops and villages of the State. At least 1000 farmers in each such area will be motivated to take up cultivation of selected crops – Orchid Valley in Zikzak horti-hub area, Kiwi Village in the uplands in the vicinity of Shillong, Strawberry Villages in other districts, Citrus Hills in the Nokrek range, Pineapple Hills in the Chibinang area, etc.

Rejuvenation of citrus & cashew: The senile plantations of citrus and cashew will be brought under systematic and scientific rejuvenation to restore the profitability of these traditional crops for the benefit of this group of farmers, especially considering the potential for export of these crops to neighboring Bangladesh.

Post harvest management and processing

Meghalaya is predominantly a horticultural state where a wide range of fruit crops both indigenous and exotic are grown abundantly in different altitudes of the State. During the peak season of harvest the State experiences glut in the market and the farmers are not getting remunerative prices for their produces. To overcome the said problem the State had established two processing centres located in Shillong, East Khasi Hills district and Dainadubi in North Garo Hills district.

The objectives of these Centres were to demonstrate, develop value addition technology for the farmers and entrepreneurs of the State. These two Processing Centres are being upgraded and the products marketed as MEG brand. The Department had initiated programme on modernization of arecanut soakage tanks traditionally practiced by the farmers. These improved technologies have generated additional livelihood to the arecanut growers of the state. The Lakadong variety of Turmeric has high Curcumin content between 7 to 8 percent. Capitalizing on the potential of the turmeric grown in the State the Government had taken step to improve the processing technology adopted by the farmers. Effort is being made to attract private investment in the PHM sector by scaling up volume of production, especially targeting niche markets outside the country and setting up of scientific modern storage facilities across the state Traditional crops like ginger, turmeric, pineapple, citrus, potato and vegetables are the mainstay of a majority of the farmers of the State.

Marketing infrastructure

Farmers markets, implemented during the 11th Plan, will be expanded to cover more areas within the State during the 12th Plan, where farmers market will be tried on the hub and spoke model – large central markets and satellite markets in their hinterland. The effective functioning of farmers markets depends to a large extent on the flow and easy availability of market related information to enable farmers to take proper and profitable market decisions based on reliable real time data. Market information system is thus a crucial and urgent intervention that would be made in order to make Farmers Markets viable and vibrant entities leading to the evolution of a much more transparent marketing system.
