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...

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...

This dataset contains supplementary material for the journal paper by Johnson et al. (2017). In the paper, OpenStreetMap crowdsourced data was used in combination with different types of satellite imagery to identify and map land cover changes in the Laguna de Bay area of the Philippines. The dataset provides the training data (derived from the...

We analyzed the change in vegetated and urban (impervious) area in the Silang-Santa Rosa sub-watershed of the Philippines to assess the implications related to flood risk. Our main findings were: -The impervious area of sub-watershed increased by 54% (from 3,239 ha. to 4,988 ha.). -The vegetated area decreased by 21% (from 8,509 ha. to 6,760 ha)....
