Abuan Watershed, Isabela

The goal of this project is to enhance the resiliency of communities and watersheds in the Abuan watershed against the worsening impacts of climate change. The project identified risks from floods and droughts due to the extensive damage caused by past events. Risks are exacerbated by massive deforestation due to upland migration, land conversion, poaching and infrastructure development. The affected human population within the watershed numbers 15,000 and consists of 3000 families covering 13 barangays. The main strategies are building and enhancing the capacities of mandated institutions such as the Local Government Unit of Ilagan City and the Cagayan Valley Integrated Agriculture and Research Center (CVIARC), an attached agency to the Department of Agriculture.

Their mandates are drawn from legal frameworks such as the Climate Change Act, DRRM Law and Forestry Code. The project will also work with the Department of Science and Technology and the Department of Environment and Natural Resources on smart farming and watershed rehabilitation. The project was able to sign MOAs with the LGU of Ilagan, DOST and DENR while awaiting signatures for the MOA with CVIARC-DA. The MOA with DOST greatly expands the project, allowing it to become part of the DOST programme on SMART agriculture.

The project will use sensor data in crop modelling for use in irrigation planning and crop monitoring. These sensors consist of agro-meteorological, soil and optical images from satellites. Agro-meteorological stations will be established in three agro-zones: floodplains, plus rolling and hilly areas. Flood monitoring sensors will be installed atop the Abuan and Bintacan bridges and a rainfall gauge shall be deployed in Divilacan. Sensor data will be inputted to three models: DSSAT, Aquacrop and the FAO hydroagronomic model.
