Although it is widely acknowledged that forests provide critical ecosystem services for human survival and well-being, in the Asia-Pacific region forests are being converted to other land uses and degraded at alarming rates. One underlying factor for this destruction of forests is market failure. Forests are cleared for other land uses or degraded...

We use crowdsourced GIS data from OpenStreetMap to help automate the mapping of land cover in Landsat satellite imagery. The OpenStreetMap data had limited area coverage, but was useful for building a model which could classify land cover in the other areas.

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)....

We developed a method for mapping residential areas using freely available satellite imagery. The resultant residential area map can be used for risk assessment (e.g. to estimate the population living in a flood-prone area). Our method can be applied for flood risk assessment in other watersheds in the future.

This dataset can be used by researchers to test different land use/land cover mapping methods using crowdsourced geographic data and Landsat satellite imagery. The study area is the Laguna de Bay area of the Philippines, and the satellite data is from 2014-2015. This dataset will also be available on the "UCI Machine Learning Repository" (https:/...

We developed a fast method for land cover mapping using satellite imagery and crowdsourced geographic data (land use polygon data). The method is less time- and labor-intensive than traditional land cover mapping methods because the crowdsourced data substitutes for training data collected the traditional way (through field survey or visual image...
Policy Brief
IGES Policy Brief
Partly due to the worldwide upsurge in industrial demand for timber, the number of planted forests has increased ten-fold in the last 20 years. These planted forests currently comprise only about 5% of the world’s forest area, but supply 35% of industrial logs and have critical roles to play in releasing pressure on natural forests, mitigating...
Policy Report
This study examines two major transitions in forest governance - decentralisation and state-sponsored (formal) community forestry - with respect to whether they are opening spaces for communities to contribute to sustainable forest management. Our main thesis is that there is a need for democratic decentralisation in order to effectively re-engage...
