Tropical dry forests and savannas are important repositories of plant diversity and ecosystem services in the tropics. These ecosystems are also used extensively for grazing by livestock, and represent a critical element of the rural economy of many tropical countries. Fire is considered as a part of co-evolution in these ecosystems across the globe. However, in recent decades, there has been a shift in historical fire regime. Fire has become more frequent in these landscapes, and could be further enhanced under climate change.
Today, most wild tigers live in small, isolated Protected Areas within human dominated landscapes in the Indian subcontinent. Future survival of tigers depends on increasing local population size, as well as maintaining connectivity between populations. While significant conservation effort has been invested in increasing tiger population size, few initiatives have focused on landscape-level connectivity and on understanding the effect different landscape elements have on maintaining connectivity.
Watershed development (WSD) is an important and expensive rural development initiative in India. Proponent of the approach contend that treating watersheds will increase agricultural and overall biomass productivity, which, in turn will reduce rural poverty. We used satellite measured Normalized Differenced Vegetation Index as a proxy for land productivity to test this crucial contention. We compared micro-watersheds that had received funding and completed watershed restoration with adjacent untreated micro-watersheds in the same region.
A dearth in understanding the behavior of Asian elephants (Elephas maximus) at the scale of populations and individuals has left important management issues, particularly related to human-elephant conflict (HEC), unresolved. Evaluation of differences in behavior and decision-making among individual elephants across groups in response to changing local ecological settings is essential to fill this gap in knowledge and to improve our approaches towards the management and conservation of elephants.
Recent studies have documented changes in vegetation cover due to invasive herbivores in the Andaman Islands. In this study we demonstrate that the change is large enough and rapid enough to be detected by remotely sensed data. Using the freely available Nor-malised Difference Vegetation Index (NDVI) imagery, we examined changes in vegetation cover due to the presence of invasive herbivores in the Andaman Is-lands. Two time-periods were analysed using different types of imageries.
This document presents results of an ongoing rapid assessment of eight village lying in three districts of the Wajir
county. A multiple stage survey was conducted in these villages. Participants during the survey included village
elders, the government appointed chief. Other participants included members of village committees, women and
youth. Information collected per village varied based on the persons participating in the exercises.
The purpose of these surveys was to develop an understanding of issues pertaining to natural resource availability,
