Working Paper

While the initial pieces of evidence indicate that COVID-19 induced economic slowdown and lockdown present short-term benefits to air quality and the environment, these also pose a double-edged challenge in the long-term. On one side, the slowing down of the economy can have an adverse impact on countries’ ongoing efforts towards climate mitigation...

First Sub-Regional workshop on Preparation of status Report and Sub-regional Roadmap for Implementing the Global Waste Management Goals toward Addressing SDGs in South Asia
Author:

Home to roughly 1.8 billion people, South Asia generates approximately 334 million tonnes of waste per year of which 174 million tonnes (57%) is organic in content. In addition to the increase in municipal solid waste, managing complex and emerging waste streams, including e-waste, food waste, construction and demolition waste, disaster waste...

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)....

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 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.

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...
