Description

Watershed management is a crucial factor in prolonging the lifespan of SWIS. As a reservoir-type structure, the erosion of soil materials from the watershed and the subsequent siltation of the reservoir can shorten the life of the SWIPS Furthermore, silt accumulation reduces reservoir storage capacity and impairs the availability of water for irrigation and other purposes. In this scenario, the land use–its condition and activities done within the watershed has significant effect in the SWIS.

 

An ideal watershed for a SWIS is one with a good vegetation stand which minimizes the occurrence of soil erosion. While most watersheds have rugged topography, some have sparse vegetation cover and others have been devoted to cultivated agriculture that, when erosion control measures are not practiced, have high erosion rates. Thus, vegetation improvement and adoption of Sustainable Land Management (soil conservation and soil erosion prevention technologies) are important initiatives in the improvement of watershed conditions and in prolonging the lifespan of SWIS.

 

 

Six (6) watersheds of SWIS were selected to implement the project:

  1. Cabaroan SWIP, Balungao, Pangasinan
  2. Tibag SWIP II, Talugtug, Nueva Ecija
  3. San Antonio  SWIP, Ocampo, Camarines Sur
  4. Ding-ingan SWIP, Tapaz, Capiz
  5. Tambis SWIP, Hilongos, Leyte
  6. Lunukan SWIP, Malaybalay City, Bukidnon

Objective

To improve the conditions of the watersheds of Rainwater Harvesting Facilities, specifically, Small Water Impounding System (SWIS) through the application of Sustainable Land Management (SLM) practices/ technologies; and

To establish community-managed soil and water conservation guided farms in selected watersheds of existing SWIS of the country that will serve as models for the adoption and adaptation of SLM technologies and expected to be scaled up in other areas of the SWIS watersheds.

Activities

  • Establishment of techno-demo sites

Conduct of capacity building/farmers training

Impact

Securing the availability of productive and healthy soil resources through sustainable land management resulting in increase in farmer’s yield/income/livelihood

  • promotion/adoption of appropriate soil conservation measures
  • increase awareness of land users on soil conservation
  • widen the source of income through crop diversification
  • conservation of soil resources
  • soil conservation as climate change adaptation & mitigation strategy

Beneficiaries

Farmers association/group with areas located within the selected SWIS watershed

Status of implementation?

2022 (completed)
