As the wild tiger population in tropical Asia dropped from about 100,000 to 3,500 in the last century, the need to conserve tiger habitats poses a challenge for the Global Tiger Recovery Program. This paper develops and uses a high-resolution monthly forest clearing database for 74 tiger habitat...

Habitat conservation is critical to the survival of endangered tigers. This paper develops a resource-allocation model for the protection of tiger habitats, using information on threats to particular tiger subspecies, the quality of remaining habitat areas, the observed effectiveness of habitat...

The publication of nearly 600,000 new species occurrence maps using Global Biodiversity Information Facility data provides an opportunity to reassess international species protection with broader representation for plants, invertebrates, and other species. This development aligns with the global...

This paper investigates the effectiveness of protected areas in slowing tropical forest clearing in 64 countries in Asia/Pacific, Africa, and Latin America for the period 2001-2012. The investigation compares deforestation rates inside and within 10 kilometers outside the boundary of protected...

Biodiversity is essential for ecological stability, human well-being, and economic progress, providing critical ecosystem services such as clean water, food, and climate regulation. However, it faces unprecedented threats, with extinction rates accelerating to 1,000 times the natural baseline...

Adaptation to climate change includes addressing sea level rise and increased storm surges in many coastal areas. Mangroves can substantially reduce the vulnerability of the adjacent coastal land from inundation and erosion. However, climate change poses a large threat to mangroves. This paper...

The Millennium Development Goal of achieving near-zero malaria deaths by 2015 has led to a re-examination of wider use of DDT (dichloro-diphenyl-trichloro-ethane) in indoor residual spraying as a prevention tool in many countries. However, the use of DDT raises concerns of potential harm to the...

Scientific evidence indicates that global warming could well lead to a sea-level rise of 1 meter or more in the 21st century. This paper seeks to quantify how a 1-meter sea-level rise that would affect coastal wetlands in 76 developing countries and territories, taking into account how much of...

A spatial econometric model is used to link road upgrading to forest clearing and biodiversity loss in the moist tropical forests of Bolivia, Cameroon, and Myanmar. Using 250-meter cells, the model estimates the relationship between the rate of forest clearing in a cell and its distance to the...

This paper investigates possible impacts of climate change on the poor communities of the Bangladesh Sundarbans via changes in aquatic salinity and mangrove species. The implications for poor communities are assessed by computing changes in high-value mangrove species for the five sub-districts...
