Minerals in Meghalaya

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.

  1. forest-dependent livelihoods,
  2. pre-agricultural level of existence,
  3. stagnant or declining population,
  4. low literacy rates
  5. a subsistence-based economy.

As currently there is no tribal group included in this list.

Sixth Scheduled of Consstitution which govern these tribes

The original Sixth Schedule areas created in 1952 underwent a drastic reorganization in 1971; some areas were put under newly created States such as Mizoram and Meghalaya which were carved out of the erstwhile Assam State. The Sixth Schedule (Article 244 (2) and 275 (1)) provides for administration of Tribal Areas in the States of Assam, Meghalaya, Tripura and Mizoram through Autonomous District and Regional Councils endowed with legislative, judicial, and executive powers.

The Sixth Schedule under Article 244 (2) provides for the creation of Autonomous District Councils (ADC) in an Autonomous District and Regional Councils for autonomous regions. These Councils have legislative powers on matters relating to:

  • allotment, occupation, or the setting apart of land, other than reserved forests, for the purpose of agricultural or grazing or for residential or other non-agricultural purposes or for any other purpose likely to promote the interests of the inhabitants of any village or town (Provided that nothing in such laws shall prevent the compulsory acquisition of any land, whether occupied or unoccupied for public purpose)
  • management of any forest not being a Reserved Forest
  • use of any canal or water course for purpose of agriculture
  • regulation of the practice of jhum or any other form of shifting cultivation
  • establishment of village or town committees or Councils and their powers
  • any other matter relating to village or town administration, including village and town police, public health and sanitation
  • appointment of succession of chiefs or headmen
  • inheritance of property
  • marriage and divorce
  • social custom
  • The entire State of Meghalaya except Shillong area is covered under the provisions of the Sixth Schedule of the Constitution. Meghalaya has three Autonomous District Councils under the Sixth Schedule of the Constitution. These are –
  1. Khasi Hills Autonomous District Council (KHADC),
  2. Garo Hills Autonomous District Council (GHADC),
  3. and the Jaintia Hills Autonomous District Council (JHADC).

 

Major Tribal Group of Meghalaya

Garo Tribe of Meghalaya:

  • The Garos are mainly distributed over the Kamrup, Goalpara and Karbi Anglong districts of Assam, Garo Hills and few in Khasi Hills in Meghalaya and Dimapur (Nagaland State), substantial numbers, about 200,000 are found in greater Mymens ingh ( Tangail, Jamalpur, Sherpore, Netrakona, Mymensingh) and capital Dhaka, Gazipur, Sirajgonj, Rangpur, Sunamganj, Sylhet, Moulovibazar districts of Bangladesh. It is estimated that total Garo population in India and Bangladesh together is about 1 million.
  • They originally belong to the Bodo family from the Tibetan-Burmese race; also reside in the plains of Assam and Bangladesh.
  • The Garo language belongs to the Bodo–Garo branch of the Tibeto-Burman language family.
  • The Garos are one of the few remaining matrilineal societies in the world. The individuals take their clan titles from their mothers. Traditionally, the youngest daughter (nokmechik) inherits the property from her mother. Sons leave the parents’ house at puberty, and are trained in the village bachelor dormitory (nokpante). After getting married, the man lives in his wife’s house. Garos are only a matrilinear society, but not matriarchal. While the property is owned by women, the men govern the society and domestic affairs and manage the property. This provides security to Garo women.
  • Like other tribes in Meghalaya these tribes too follow maternal lineage in case of inheritance of property and enjoy all kind of vegetarian well as non-vegetarian food in case of regional delicacies.
  • The Garos rely on nature, their profession is hunting and warrior known as They practice jhum cultivation which is the most common agricultural tradition.
  • The most popular food of the Garo tribes is rice with capsicum, onion and salt.
  • Garo literature mainly transferred from generation to generation and one place to another orally. Most of the oral tradition now become the element of Garo literature
  • Greatest among Garo festivals is the Wangala, usually celebrated in October or November, is thanksgiving after harvest in which Saljong, the god who provides mankind with Nature’s bounties and ensures their prosperity, is honor.

Khasi Tribe of Meghalaya:

  • According to the 2011 Census of India, over 1.72 million Khasi lived in Meghalaya in the districts of East Khasi Hills, West Khasi Hills, South West Khasi Hills, Ri-Bhoi, West Jaintia Hills and East Jaintia Hills. In Assam, their population reached 35,000.
  • They are the largest tribal group of North eastern region. Khasis are known with a number of names in different parts of Meghalaya.
  • The Khasi people of the War sub-tribe designed and built the famous living root bridgesof the Cherrapunji
  • As a religion they follow Christianity (85%), Ka Niam Khasi (10%), Hinduism (3%), and Islam (2%)
  • The Khasis are, for the most part, Their social organisation does not favour other forms of marriage; therefore, deviation from this norm is quite rare. Young men and women are permitted considerable freedom in the choice of mates. Potential marriage partners are likely to have been acquainted before betrothal.
  • The traditional political structure of the Khasi community was democratic in nature. The Khasis consisted of ‘native states’ which would congregate during dorbars or sessions and come to a decision regarding any dispute or problems that would arise in the community much like the Panchayati Raj prevalent in most Indian States

Jaintia Tribe of Meghalaya:

  • Jaintias too reside in the foot hills of Jaintia Hills from where they collect their name.
  • These are a type of Khasi tribe which further includes Bhoi in the northern Meghalaya; Khynriam in the central Meghalaya; Pnar of the Jaintia hills; War in the southern Meghalaya.
  • Achiks are another group of Garo tribes who comprise one third of Meghalaya’s tribal community.

Relief and structure of Meghalaya

Relief and structure of Meghalaya

Meghalaya is an upland area formed by a detached block of the Deccan plateau. Its summits vary in elevation from 4,000 to 6,000 feet (1,220 to 1,830 metres). The Garo Hills in the west rise abruptly from the Brahmaputra River valley to about 1,000 feet (300 metres) and then merge with the Khasi Hills and Jaintia Hills, adjacent highland systems that form a single massif of tablelands separated by a series of eastward-trending ridges. The southern faces of the plateau, overlooking the Bangladesh lowlands, is particularly steep.

Meghalaya Plateau belongs to the part of Super Continent of Gondwanaland, i.e., the Peninsular table land, but is detached from the latter by the intervening spread of the alluvium of the Ganga and the Brahmaputra. The structural history of the region reveals several phases of erosion, sedimentation, diastrophism, intrusion, movements of land and sea, and emission.

The plateau is mainly made up of rocks of the pre-Cambrian age. The pre-Tertiary and Tertiary rocks occur above these rocks on its western and southern margins. Stratigraphically the rocks of the plateau belong to five broad geological formations, namely the Archaean gneissic complex, the Shillong group of rocks, the lower Gondwana, the Sylhet traps, and Cretaceous – Tertiary – Quarternary Sediment.

The Archaean-gneissic complex occupies the central and northern parts of Meghalaya Plateau. The rocks include gneiss, granite, quartzites, schists, etc. The Shillong group of rocks lying unconformably over the gneissic complex, occurs in the central and eastern parts of the plateau These include phylite, quartzites, schists and conglomerates.

The lower Gondwana rocks are found in the western part of Garo Hills which include pebble beds, sandstones and shale. The Sylhet trap is exposed along the southern border of the Khasi Hills in an east-west direction, and rests unconformably over the eroded pre-Cambrian basement rocks. These rocks are predominantly basalt, rhyolite and acid tuffs.

The Garo Hills region of the State, in its greater portion, is formed of gneissic rocks overlaid by sandstones and 1 conglomerates of Cretaceous-Tertiary system.

The sediments of this system of rocks are known as the Garo group in the region. This group of rocks is again divided into the Simsang, Baghmara and the Chengapara formations. The Simsang is the oldest formation in the Garo group which lies conformably over the Kopili series (the youngest formation of the Jaintia group of Cretaceous – Tertiary sediments), and consists of siitstone and sandstone.

the Baghmara formation includes sand, pebble, conglomerates and clay which lie conformably over the Simsang formation. The Chengapara formation consists of sand, siitstone and clay. On the top of these Cretaceous-Tertiary formations rests limestone of Numulitic age, while sandstones of upper Tertiary origin form low hiiis along the Mymensing border.Relief and structure of Meghalaya

The Khasi Hills are located east of the Garo Hills. The other Khasi tribes did not have princes but their twenty petty states (hima), and sometimes even smaller tribal divisions, are led by one or two Chiefs -selected in various ways- usually styled Siem, Syiem.  The names of these chieftainships are : Bhawal, Cherra (or Sohra; capital Cherrapunji), Dwara (capital Hat Dwara), Jirang, Khyri(e)m (capital Cherrapunjee, under a Radja), Langrin, Lungiong, Maharam, Malai Sohmat, Marriw, Mawdon, Mawiang, Mawlong, Mawphlang, Mylliem (including Shillong city, the colonial capital of all Tribal Assam), Nobosohphoh, Noglwai, Nongkhlaw, Nongspung, Nongstoin, Pamsanggut, Rambrai, Shella, Sohiong. or Sardar .

The Jaintia Hills are located further to the east from the Khasi Hills. The twelve Chiefs of the elaka (tribal province) of the Jaintia, a Khasi subtribe of the) Pantars = Syntengs tribes, are styled Dolloi, and the land is called after them in Khasi: KA RI KHADAR DOLLOI ‘Land of 12 Tribal Chiefs‘) – they are in Nartiang itself (see the Raja, uniquely also styled, as premier Chief: U Kongsong), and in Amwi, Jowai, Lakadong, Mynso, Nongbah, Nongjngi, Nongphyllut, Nongtallang, Raliang, Shangpung, Sutnga (see below; also cited as seat of a Syiem)  Above them is the only true princely ruler of the area, the Raja of Jaintiapur.

His winter capital is now in Bangladesh, with his summer residence shifted from Sutnga (where the family started as Syiems) to Nartiang; also a palace in the commercial center Borghat.  The Jaintia Hills used to be a part of the Jaintia Hills District. The district has been bifurcated into two separate districts,namely, East Jaintia Hills and West Jaintia Hills on 31 July 2012.

 

Rivers and drainage system of Meghalaya

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 MeghalayaNagaon. 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.

 

Natural hazards and related issues of Meghalaya

Natural hazards and related issues of Meghalaya

As the State lies in the seismically active zone, special emphasis should be given to reduce the impacts of earthquake. Moreover, it is also affected by hazards such as floods, flash floods, epidemics, fire, hailstorm, lightening, road accidents, etc.

Earthquake

The State of Meghalaya has witnessed seismic events of ‘8.7 magnitude in 1897’. This region has been identified as a potential site of a future catastrophic earthquake. With the growth of population and infrastructure seismic vulnerability has increased and previous earthquakes have provided a glimpse of the devastating potential of seismic tremors.

Cyclones

Meghalaya is situated in the north eastern direction of Bangladesh which is highly prone to cyclone/ winds. Every year about 60% of the area is affected by cyclone in Bangladesh. The Districts of West Jaintia Hills and East Jaintia Hills may experience a wind speed of up to 55m/s. Occasional cyclones do occur in western Meghalaya their severity being more during monsoon season. The Districts close to Bangladesh like South West Garo Hills, South Garo Hills, South West Khasi Hills, West Khasi Hills, fall in very high cyclonic zone due to close proximity to Bay of Bengal (which is a cyclone basin). In this zone wind speed can reach up-to 50 m/s, which can cause large scale damages. The Bay of Bengal accounts for seven percent of the annual tropical cyclone activity worldwide; the recorded frequency of cyclones per year along the Bay of Bengal is four and inevitably one of the four transforms into a severe cyclone causing human and property losses

Floods

The State with hilly terrain does not suffer from a major problem from floods, However, due to heavy rain, flash floods may be caused resulting in river bank erosion and some local damage. In Meghalaya, Natural hazards and related issues of Meghalayafloods occur in river valleys, when flow exceeds the capacity of the river channel, particularly at bends or meanders. The plain areas of Meghalaya adjoining Assam are affected by flood due to the back flow of water from the River Brahmaputra during the flood season between June and October. The tributaries like Krishnai, Jinari, Jingjiram, Rongai, Dudhnoi, Ringgi, Gohai, Dilni etc cause flood in the plain areas of the State.

Landsides

Meghalaya being a hilly terrain is prone to landslides. Every year a number of landslides have been reported from various localities. These cause a lot of miseries to public, resulting in loss of lives and properties, disruption of communication network, besides causing economic burden on the society. Landslide is primarily attributed to high slope, immature geology, neo-tectonic activity, heavy rainfall, unplanned and improper land use practice in the State. Landslides generally occur during heavy rains, that is during the months of June to October in Meghalaya.

Southern part of Meghalaya is more susceptible to Landslides than the Northern Part. National Highways like Bajengdoba-Tura-Dalu, Damra–Siju-Baghmara, Guwahati – Shillong- Tamabil, and Shillong- Jowai- Badarpur are prone to landslides.

Landslide occurred frequently at Sonapur on Shillong- Jowai- Badarpur Road, but now the problem has been mitigated by constructing a tunnel for the vehicular traffic. Urban areas of Shillong and Tura, Jowai are also prone to landslides due to the faulty Construction of Houses and rapid Urbanization.

Lightning and Hailstorms

Lightning occurs during the monsoon months and can strike at any place. Hailstorm generally occurs in the pre and post monsoon months. Some loss of crops lives and properties due to lightning and hailstorms are reported in the state.

Hazard Specific Mitigation Plan

The State Disaster Management Authority was established in the State under the Chairmanship of the Chief Minister with 8 other members under section 14 of the Disaster Management Act, 2005 by a Government notification dated 26th June, 2008. It is the apex body for disaster management in the State.

The State Executive Committee headed by the Chief Secretary with 4 other Secretaries as members was also set up to assist the State Disaster Management Authority in the performance of its functions.

The District Disaster Management Authorities under the Chairmanship of the Deputy Commissioners and Chief Executive Members of the District Councils as Co-Chairmen with 5 District Officials as members were also set up for the better management of disasters in the Districts.

Similarly at the Block and Village levels Block Disaster Management Committee and the Village Disaster Management Committee were set up headed by the respective Block Development Officers and the Village Headmen. The State Disaster Management Authority, has set uMock drill by NGO’sMock drill by NGO’sp a State Disaster Management Secretariat in 2010 which is located in the Office of the Director of Land Records and Surveys, Lower Lachumere, Shillong. The day to day functioning of the SDMA is looked after by the Executive Officer of the Secretariat.

Functions of SDMA

Framing of Disaster Management Policy and the preparation of the State Disaster Management Plan, reviewing the preparedness, prevention, mitigation and capacity building measures in the State.

Activities of SDMA

The preparedness, prevention, mitigation and capacity building programmes.

The Disaster Risk Reduction Project funded by the UNDP which focuses on the awareness programmes, capacity building, strengthening of the disaster management institutions are being implemented in the three districts of East Khasi Hills. West Garo Hills and the Jaintia Hills, While the Urban Risk Reduction Programme is being implemented in the capital city Shillong through the SDMA Secretariat the Capacity Building Programme is under the 13th Finance Commission.  Besides, Hazard Risk Vulnerability Assessment (HRVA) will also be carried out for the Shillong city and the West Garo Hills through North Eastern Space Application Centre, Umiam.

State Disaster Response Fund is available for management of disasters in the State. An advance amount from the fund is made available to the Deputy Commissioners to meet any emergency arising out of disasters.

 

 

 

Irrigation and hydro power of Meghalaya

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.

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.
