This fact sheet shows flood modeling results for the San Juan subwatershed of the Philippines. The flood-affected area is expected to increase by ~10% from 2015-2025 due to planned land-use changes.

This fact sheet shows flood modeling results for the San Cristobal subwatershed of the Philippines. The flood-affected area is expected to increase by ~47% from 2015-2025 due to planned land-use changes.

Japan is one of the prominent contributors towards overseas development assistance (ODA) and emergency relief assistance (external emergency assistance, EEA) in the aftermath of major natural disasters. These assistances have costs and benefits to both the recipients and to the donor countries. In order to improve the efficacy of various forms of...

This 1-pager shows the potential impacts of land-use change on flooding in the Los Baños subwatershed of The Philippines. The built-up area of the subwatershed is projected to increase by ~65% (based on participatory mapping exercises conducted with local government staff members), which is estimated to result in a ~6% increase in the flood...

This 1-pager shows the potential impacts of land-use change on flooding in the Pila-Victoria subwatershed of The Philippines. The built-up area of the subwatershed is projected to increase by ~88% (based on participatory mapping exercises conducted with local government staff members), which is estimated to result in a ~5% increase in the flood...

Considering the finite volume of fresh water resources, managing its quality and quantity sustainably is one of the greatest challenges because of complex global changes. This work strives to predict the combined effect of urbanization and climate change on water quality in Pasig-Marikina River considering its criticalities to develop proactive...

Literature suggests a significant potential for synergies among climate change adaptation and mitigation (CCA & M) policies, especially in urban areas. However, the understanding of how best to integrate CCA &M is limited despite the fact that there is an increasing interest, particularly in Southeast Asian countries, in achieving the integration....

This study uses a spatially-explicit land-use/land-cover (LULC) modeling approach to model and map the future (2016–2030) LULC of the area surrounding the Laguna de Bay of Philippines under three different scenarios: ‘business-as-usual’, ‘compact development’, and ‘high sprawl’ scenarios. The Laguna de Bay is the largest lake in the Philippines and...

Land cover change (LCC) can have a significant impact on human and environmental well-being. LCC maps derived from historical remote sensing (RS) images are often used to evaluate the impacts of past LC changes and to construct models to predict future LC changes. Free moderate spatial resolution (~30 m) optical and synthetic aperture radar (SAR)...

This is the summary of the country drought risk reduction assessment done as a part of the JICA-ASEAN project on integrating climate change adaptation and disaster risk reduction into institutional and policy processes (CN 20). The Philippines has made significant progress in understanding the El Nino and transferring the weather information to...
