Why organize LGUs for watershed management? 2 nd Jalaur Watershed Stakeholders’ Assembly December 20, 2005 Jessica Calfoforo Salas, Co-Chair TWG of Iloilo Wateshed Management Council

The Natural Untreated Watershed

Runoff water spreads over landscape through a network of rills and gullies to the canals Entire landscape is moistened but there is little absorption in the soil profile. Most of the rain water flows out resulting in erosion and expansion of rills and gullies. Crop yields fluctuate with monsoon and during drought years. Crops suffer substantially.

There is little green fodder on grazing grounds Trees have stunted growth Drinking water is diminishing. Degradation of natural resources results in poverty, malnutrition, hunger, illiteracy, etc.

Treated Watershed For Specific Purpose

Watershed treated for a specific purpose (NGAs) The objective of maintaining a watershed for a reservoir for domestic use, irrigation, hydro- electric power: maximum water and minimum silt should reach the reservoir. Sole disposal of rainwater through diversion drains, contour bunds, waste weirs, grassed water ways, drop structures and series of check dams in the drainage line to detail silt and allow water to pass downstream. This approach succeeded in temperate climates where rainfall is equitably distributed but in tropical areas, it is not successful.

With emphasis on safe disposal of water, there is little impact on recharge. Contour bunds are difficult to make due to small holdings and straight property boundary lines Production system is not the primary concern. Structures are costly and require regular maintenance

Integrated Watershed Management

Watershed with Integrated management Objective is conservation of water and spreading the benefit of water during rainy season Collection of rainwater in sunken ponds (natural & dugout) promoting the recharge of sub surface water (open well) or ground water are the main hydrological principles.

Maximum possible surface flow should be converted into sub- surface flow to moisten the soil profile and promote deep percolation Main devices are village ponds, wells, trenches, and vegetative hedges and percolation ponds all over landscape. Minimize flow to the drainage line. This is a holistic principle to collect retain and use rainwater for human and livestock drinking, domestic use, life-saving irrigation, vegetable cultivation and initial watering of horticultural and forest trees.

Availability of water is improved permitting its multiple use. Crop loss during drought years is minimized. Growth of pasture and establishment of trees is facilitated Higher yield of food, fodder, fuel and small timbers initiates socio-economic rehabilitation Improved availability of water in the foundation of growth and development.

The watershed management structure is only a shell. What will make a difference are the actions in each barangay.
