Loktak Lake:★ Loktak Lake is the largest freshwater lake in Northeast India and is famous for the phumdis floating over it.★ Phumdis are the heterogeneous mass of vegetation, soil and organic matter at various stages of decomposition.★ Keibul Lamjao National Park is also one of Phumdis in the lake.★ It is only floating national park in world and is last natural refuge of endangered Sangai deer.★ This ancient lake plays an important role in the economy of Manipur.★ It serves as a source of water for irrigation, drinking water supply and hydropower generation.★ Considering the ecological status and its biodiversity values, Loktak lake was initially designated as a wetland of international importance under the Ramsar Convention in 1990.★ Later it was also listed under the Montreux Record in 1993.★ Human activity has led to severe pressure on the lake ecosystem. |
National river connectivity programme:★ The National River Linking Project (NRLP), envisages the transfer of water from water ‘surplus’ basins where there is flooding to water ‘deficit’ basins where there is drought/scarcity, through inter-basin water transfer projects.★ It links rivers by a network of reservoirs and canals that will allow for their water capacities to be shared and redistributed.★ This is an engineered panacea that will reduce persistent floods in some parts and water shortages in other parts besides facilitating the generation of hydroelectricity for an increasingly power hungry country.Components of River Linking ProjectsIt has been split into three parts:1. Northern Himalayan Rivers interlink component.2. A southern peninsular component.3. An intra-State rivers linking component.Benefits of the River Linking Projects:★ The river interlinking project claims to generate total power of 34,000 MW (34 GW).★ The project claims to provide additional irrigation to 35 million hectares (m ha) in the water-scarce western and peninsular regions, which includes 25 m ha through surface irrigation and 10 m ha through groundwater.★ It will lead to Ground water Recharging.★ The inter-link would create a path for aquatic ecosystems to migrate from one river to another, which in turn may support the livelihoods of people who rely on fishery as their income. |
Zoological Survey of India:★ The Zoological Survey of India (ZSI) was established on 1st July, 1916 to promote survey, exploration and research leading to the advancement in our knowledge of various aspects of exceptionally rich life of the erstwhile ´ British Indian Empire.★ Institution Headquartered in Kolkata.Objective:★ Exploration, Survey, Inventorying and Monitoring of faunal diversity in various States, Ecosystems and Protected areas of India.★ Periodic review of the Status of Threatened and Endemic species.★ Preparation of Red Data Book, Fauna of India and Fauna of States.★ Bio ecological studies on selected important communities/species.★ GIS and Remote Sensing studies for animal diversity as well as for selected threatened★ Chromosomal Mapping and DNA finger printing. |
