 Apex Mission Nepal’s Involvement and successful completion of the project:

Apex Mission Nepal (AMIN) intends to work in the direction of ending water poverty in the hills and plains of Nepal by implementing long term water resource management interventions. Community based water resource management technology has been practiced in its rudimentary form by communities in water scarce areas of Nepal to survive in adverse situation. Since long, farmers have developed their own system of collecting rainwater for irrigation. The traditional practices vary depending upon the topography, soil, specific sites and seasons etc. In the recent years AMIN has conducted research in gathering information about the traditional best practices of managing water resources including rainwater harvesting in the mid hills of Far Western Nepal. On this foundation, AMIN proposes to implement its long term water resource management project in three districts of Far Western Nepal namely: Dadeldhura, Doti and Kailali. A prefeasibility study of the project relevance has shown that major part of these three district experience severe water shortage during post and pre monsoon period. However the average annual rainfall of this area remains 1400 mm which if managed properly through watershed management practices will be more than enough to fulfill the domestic needs of the communities residing on these settlements and further it also helps to prevent over flooding during the monsoon period consequently reducing the siltation of lakes and rivers downstream.

 

In mountain watersheds, energy and matter flow downwards with gravity. This has on- and off-site effects from source to sink, and watershed management has to account for these flows. The devastating landslide and mass wasting in the upper watersheds are usually blamed on local people overexploiting natural resources. But many catastrophes are natural events. The accumulation of sediments in river channels, intense human pressure on riverbank areas, construction, and excavation of channels increase the risk of downstream flooding. Watershed management uses a series of landscaping measures to break the speed of run-off, spread and retain water over larger areas and avoid unwanted deep drainage. In wet watersheds the objective is to avoid over drainage from gullies and retain water to improve the reliability of rain-fed farming, whereas in dry watersheds run-off infiltration and recharge for water supply in the dry season is the prime purpose. AMIN hereby considers supporting the communities of mid hills in managing the water resource of hilly Nepal for improving the livelihood of hilly communities and conserving the mountain ecosystem.
