An Assessment of Water Security, Development, and Climate Change in Iloilo, Philippines and the Tigum-Aganan Watershed
This case study is a water security assessment of Iloilo, a city in the Philippines that has been one of three participating in the USAID/ Philippines City Development Initiative, part of the Partnership for Growth initiative.
Field work was carried out to 1) identify current and future water security and climate risks to Iloilo’s economic growth; (2) engage local partners in the assessment, laying the foundation to build capacity and ownership; and (3) identify and analyze a set of options for addressing these risks. A key focus was on the city’s watershed.
Climate variability is already impacting water security and climate change threatens to further undermine it. Projected impacts include sea level rise on this coastal area, higher temperatures and more intense rains.
The report provides options for improving Iloilo’s water security. These are: evaluate resources; improve knowledge management; augment water supplies; improve water quality and sanitation; reduce flood risks; reform sector governance; and demonstrate cross-cutting solutions.
Each option examines cost, effectiveness and feasibility and includes specific actions tailored to IloIlo. It then uses these barometers to rank adaptation options and lay out how long it would likely take to implement each one.
