Assessing vulnerability to climate change and variability is an important first step in evolving appropriate adaptation strategies to changing climate. Such an analysis also helps in targeting adaptation investments, specific to more vulnerable regions. Adopting the definition of vulnerability given by IPCC, vulnerability was assessed for 572 rural districts of India. Thirty eight indicators reflecting sensitivity, adaptive capacity and exposure were chosen to construct the composite vulnerability index. Climate projections of the PRECIS model for A1B scenario for the period 2021-2050 were considered to capture the future climate. The data on these indicators were normalized based on the nature of relationship. They were then combined into three indices for sensitivity, exposure and adaptive capacity, which were then averaged with weights given by experts, to obtain the relative vulnerability index. Based on the index, all the districts were divided into five categories with equal number of districts. One more district was added to 'very high' and 'high' categories. The analysis showed that districts with higher levels of vulnerability are located in the western and peninsular India. It is also observed that the highly fertile Indo-Gangetic Plains are relatively more sensitive, but less vulnerable because of higher adaptive capacity and lower exposure.Keywords

Despite the spectacular success of the green revolution and achieving self-sufficiency in food production, there are increasing concerns on sustaining the pace of agricultural growth to feed the large population of our country. Lack of yield breakthroughs, deteriorating soil health, groundwater depletion, declining size of operational holdings and labour shortage are some of the prime reasons for slow growth of agriculture. In the recent past, these constraints have been further aggravated by global climate change and climate variability. The impacts of climate change on agriculture are being witnessed globally, but countries such as India are especially vulnerable in view of the high population depending on agriculture, excessive pressure on natural resources and poor coping capabilities.Full Text

A field experiment was conducted at the Agricultural College, Bapatla, AP, India during kharif and rabi seasons from 2019 to 2021 using different establishment and nutrient treatments. The objectives of this study were to evaluate the energetics between the treatments in the rice–green gram. The results indicated that the input and output energy were the highest in the conventional and the lowest in the minimum tillage. Highest total energy productivity and energy use efficiency were recorded with the reduced tillage. In case of nutrient management, the highest input, output energy and energy productivity and energy use efficiency were recorded with inorganic fertilizer + cured poultry manure treatments. It can be concluded that the reduced tillage with the application of inorganic fertilizer + cured poultry manure is the best in the constraints-prone coastal zone with limited irrigation facilities due to low requirement of non-renewable energyKeywords
