In the Neotropics the predominant pathway to intensify productivity is generally thought to be to convert grasslands to sown pastures, mostly in monoculture. This article examines how above-ground net primary productivity (ANPP) in semi-natural grasslands and sown pastures in Central America respond to rainfall by: (i) assessing the relationships between ANPP and accumulated rainfall and indices of rainfall distribution, (ii) evaluating the variability of ANPP between and within seasons, and (iii) estimating the temporal stability of ANPP.

Soil organic carbon (SOC) is the largest among three major carbon pools of global ecosystems. During the past few years, global warming and forcible land-use changes have resulted in a huge loss of this major carbon pool and as a consequence, concentration of atmospheric CO2 has increased. To mitigate the potential risks arising from atmospheric abundance of CO2, adoption of carbon sequestration strategies at different landscape scales is a major option. For this

Industrial agricultural plantations are a rapidly increasing yet largely unmeasured source of tropical land cover change. Here, we evaluate impacts of oil palm plantation development on land cover, carbon flux, and agrarian community lands in West Kalimantan, Indonesian Borneo. With a spatially explicit land change/carbon bookkeeping model, parameterized using high-resolution satellite time series and informed by socioeconomic surveys, we assess previous and project future plantation expansion under five scenarios.

This article examines the implementation of the Forest Rights Act of 2006 in the historical context of Wayanad’s adivasi land struggles. The left-wing Government of Kerala (2006-11) aimed to interpret the FRA as a legal opportunity to obtain forest (department) land and to fulfil decade-old promises to redistribute land to landless adivasis. However, the provisions of the Act were not the right means to bring them redistributive justice. The well-intentioned FRA failed to make an impact in the specifi c historical and legal environment of the region.

We conducted a survey in Kerala from December 2009 to March 2010 to document Nilgiri Tahr Nilgiritragus hylocrius (Ogilby) populations in fourteen sites that ranged from Neyyar Wildlife Sanctuary in the southern Western Ghats to Silent Valley, north of the Palghat Gap. The total sightings of the Nilgiri Tahr over the course of the survey were 235 animals, of which yearlings and kids constituted 12%.

This article will present basic facts on limitations and efficacy of large water storage versus small dams & popularly known as rain water harvesting structures (rwhs) for recharging ground water and suggests serious examination of mother statements about relation of forests and hydrologic elements.
