NASA: Deforestation jumps in Malaysia

Deforestation jumped during the first three months of 2013 in Malaysia, Nepal and Mexico, according to a forest tracking tool developed by a team of NASA researchers.

NASA’s Quarterly Indicator of Cover Change (QUICC), a MODIS satellite-based product that underpins’s Global Forest Disturbance Alert System (GloF-DAS), picked up strong deforestation signals in five countries during the first quarter of 2013: Malaysia (115 percent increase in deforestation), Nepal (114 percent), Mexico (92 percent), Argentina (72 percent), and Madagascar (51 percent).

According to Christopher Potter, a Senior Research Scientist at NASA Ames Research Center who co-led development of the tool, hotspots in each country include:

However GloF-DAS also showed large drops in deforestation compared to a year earlier in several key tropical countries, including DRC-Congo (94 percent drop), Thailand (84 percent), Myanmar (81 percent), Vietnam (72 percent), Lao PDR (57 percent), Gabon (52 percent), Nigeria (48 percent), Brazil (42 percent), Colombia (36 percent), and India (37 percent).

Indonesia, the country with the second-highest rate of forest loss among tropical countries, saw its forest disturbance rise 3 percent during the period.

GloF-DAS relies on NASA’s Moderate Resolution Imaging Spectroradiometer (MODIS) sensor to detect changes in forest greenness cover relative to the year-earlier period. It registers change in all forest and woodland areas that have lost at least 40 percent of their green vegetation cover over the past year. Seasonal variation is generally mitigated through the product’s quarterly baseline, although changes in some parts of the world, like boreal regions, can be affected by snow and ice distribution.

The tool can help highlight areas where deforestation and forest degradation is occurring on a quarterly basis, potentially providing insight to authorities, policymakers, civil society, local communities, and academics.

GloF-DAS was developed in a partnership between NASA Ames Research Center, Cal State Monterey Bay, and
