Local adaptation strategies in semi-arid regions: study of two villages in Karnataka, India

Rural people in India, particularly farmers, are exposed to climate variability and risk, which is likely to increase due to climate change. This study assessed current adaptation strategies adopted by rural households in two dryland villages of Bagepalli Block, Chikballapur district, Karnataka, in southern India. The adequacy of adaptation strategies was also assessed. The study showed that rural households, and farmers in particular, adopted several practices to cope with current climate risks which include irrigation provisioning (depending on groundwater), shifting cropping pattern (to more resilient but low economically valued crops and varieties), mixed cropping, agroforestry (as a long-term strategy), diversified livestock holdings, and reliance on government development programmes. The adaptation measures also included leaving croplands fallow, sale of assets such as livestock and trees, and migration. Current climate-related responses to agricultural distress are not adequate to cope with even existing climate risks. This further indicates that rural households may not be able to cope with increasing climate variability and climate change. Thus, there is an urgent need to better understand current adaptation strategies and to enhance resilience, and to develop structured adaptation strategies to cope with the risks associated with current and long-term climate change

Biophysical quantification of biodiversity and ecosystems services of forest ecosystems in the Western Ghats: a case study of Uttara Kannada District, India

Biodiversity and ecosystem services play key roles in future economic strategies seeking to promote development and prosperity. This study assesses the status of biodiversity and flow of ecosystem services from selected forest types in the Western Ghats. At the sampling sites, the number of tree species ranged from 16 to 79 per hectare depending on the forest type. The estimates for Shannon-Wiener index for trees in the evergreen, moist deciduous and dry deciduous forest plots were 3.02, 2.9 and 1.54, respectively. The total biomass carbon stocks in evergreen, moist deciduous and dry deciduous forests in the study area was 229, 221 and 189 t C/ha, respectively. Analysis of dependency patterns of local communities on forest resources indicated a high dependency on provisional services such as fuelwood, manure and fodder. The study records the highest dependency rates for fuelwood, ranging between 72 and 100% for the three forest types and indicates that forest ecosystems underpin the well-being of the population dependent directly and indirectly on them
