In conventional wetland paddy cultivation, all natural vegetation is removed during the establishment of the crop. This in turn eliminates all natural animals living within the ecosystem. In the humid tropics where wetland paddy is widely grown and the natural ecosystem can be very rich, this complete elimination of biodiversity could have serious repercussions. To reduce the loss of...
Climate change is already affecting California’s water resources. Bold steps must be taken to reduce greenhouse gas emissions. However, even if emissions ended today, the accumulation of existing greenhouse gases will continue to impact climate for years to come. Warmer temperatures, altered patterns of precipitation and runoff, and rising sea levels are increasingly compromising the...
The tropical portion of the Andean mountainous range plays a crucial role in the future quality of human life on Earth. This ecosystem is currently facing a social and environmental crisis and is in urgent need of pro-active intervention for the recuperation of its fundamental role in the hydrological cycle of the South-American sub-continent. In recent years the accelerated melting of...
At the Kennesaw Mountain National Battlefield, operated by the National Park Service (NPS) near Atlanta, differing uses – including walking for fitness, horseback riding, and organized crosscountry running team practices on the trails – conflict with the NPS mission to protect the historic resources of the site and lead to conflicts among visitors.

The presentation examines the challenges for research focusing on the poverty-environment nexus in the lower Mekong basin. First results are described, linking regional land cover dynamics to environmental service provision. In conclusion, the future outlook looks at linking landscape mosaics to socio- economic disparities and stakeholders.
Fragile ecosystems are important for their unique features and resources. These include mountains, deserts, semi-arid lands, wetlands and coastal areas. Many of the protected areas and islands can also be considered as fragile, and their concerns are important. Fragility is defined as the 'vulnerability of the ecosystems to external stresses either natural or man-made'....
