Aidenvironment assists with catchment planning in the Philippines

The Philippines are highly vulnerable to the impacts of climate change. The Baoy Catchment in Surigao Del Norte Province on Mindanao is no exception. Current water-related issues in the catchment include for example flooding, saltwater intrusion and siltation of rivers and irrigation infrastructure. These issues will probably get worse in the future due to climate change and deforestation.  

Johanniter and the Hinatuan Passage Development Alliance (HIPADA) are currently implementing a project in 9 municipalities in the region, “developing and applying participatory governance in local climate change action planning, mainstreaming in local development plans and mobilizing public funding for municipal wide resilience strengthening programs”. HIPADA requested RAIN, a brand of Aidenvironment, to support this program with technical assistance and trainings. RAIN’s first assignment under this program focuses on the Baoy Catchment.  

RAIN first performed a remote analysis of the catchment, estimating water balances and creating maps of relevant catchment characteristics and provisional zones associated with risks related to land and water. RAIN is currently providing a series of practical online trainings in Recharge, Retention and Reuse of water (3R) to selected municipalities; in this training, catchment issues are discussed and ideas for solutions are developed. 

Combining the remote analysis and local knowledge of training participants is leading to many promising options to solve catchment issues and enhance climate resilience. After further discussion and selection, these will be described in an intervention plan for the Baoy Catchment. Some examples of interventions that are being considered are cascades of small dams upstream, bamboo strips along roads, over-irrigation and “sponge city” approaches in some villages. Most options are low-cost solutions that require little maintenance.
