Abuan Integrated Watershed Management Project

Abuan Integrated Watershed Management Project

Isabela Province in the Cagayan Valley is the country’s top corn producer. Climate Change poses long-term threats to the livelihoods of farmers and to national food security. According to PAGASA, the 2050 scenario in Isabela will result in a 1.9 to 2.1 C increase in temperature; a 29% decrease in mean rainfall for dry months and a 1.7% to 25.1% increase in rainfall for wet months. This will translate to frequent and more intense flooding and dry spell events resulting in recurring crop damage and worsening poverty. Improving the resiliency of watersheds and communities to adapt to climate change impacts is crucial more than ever.

The Abuan Integrated Watershed Management Program (AIWMP) is a five-year, Php 55 million ($1,3million), project in partnership with the Department of Science and Technology (DOST). The AIWMP pilots DOST’s smarter agriculture program by enhancing the capacity of farmers to adapt to climate change.


  1. Completion of vulnerability assessments and development of 3D flood and hydro-agronomic models for climate change scenario simulation;
  2. Development of early flood warning system for flood plain communities;
  3. Dissemination and use of climate data by farmers to inform strategies on crop selection and water management;
  4. Development of disaster risk mitigation plans, forest land use plans and Integrated Water Resources Management Plan; and
  5. Facilitation of community access to water supply, irrigation, hydropower and ecotourism projects through Public Private Partnerships.


  1. 63,000 hectares of watershed area and biologically significant forests under improved management, 320 hectares established for agroforestry, and 200 farmers trained
  2. Collaboration with DOST, PAGASA, Isabela Provincial Office, Iligan City and Barangay Government Units, Cagayan Valley Integrated Agricultural Research Center, Isabela State University-Echague, Department of Environment and Natural Resources and Department of Agriculture institutionalized
  3. Capacities of watershed communities, LGUs, National Agencies and other stakeholder groups enhanced

To catalyze local stakeholder support in improving the climate change adaptability of watersheds, farmlands and other economic sectors in the Abuan Watershed.


Simulation Models: Develop climate models and build scenarios on the impacts of climate change on agriculture, forests, watershed resources, livelihoods and ecotourism.

Capacity Building: Enhance capacities and institutional arrangements for the management of the Abuan Watershed.

Ecosystem Services: Conserve and harness the abilities of the watershed to provide ecological functions such as water retention and soil stabilization.

Sustainability: Catalyze investments in hydropower, ecotourism, water supply and irrigation in order to provide incentives for watershed management.
