Conference Proceeding

Climate Change and Indian Agriculture

Mr. Durgesh Singh

Climate change is solemn environmental concern which adversely affecting agricultural production and productivity. It refers to a statistically significant variation in either the mean state of the climate or its variability, persisting for an extended period. As the temperature and resource availability varies between different countries it results in variation of agricultural contribution to climate change. In developing countries, Green House Gas (GHG) emission from agriculture sector is much more because of large number of ruminant cattle, indiscriminate use of agro-chemicals and mismanagement of the land. Globally, agriculture contributes to 58% of total nitrous oxide (N2O) emission. N2O and methane (CH4) are two of the most potentnon-CO2 GHG, which contributes about half of the global emissions of the world. Of the total annual crop losses in agriculture, many are due to direct weather and climatic effects such as flood, drought, frost, heat and cold wave etc. The impact of climate change on water availability will be particularly severe for India. About 54 percent of India’s groundwater wells are decreasing, with 16 percent of them decreasing by more than one meter per year. Dynamic of pests and diseases will be significantly altered leads to the emergence of new patterns of pests and diseases which will affect crops yield. In addition to the basic role of agriculture to produce food, fiber, fodder and raw materials for uses, it also performs maintains the renewable natural resources, construction and protection of land, conservation of biodiversity and the maintenance of socio-economic activities. Agriculture sustenance human life that also affected by climate change. In India, climate is mainly influenced by its geography that controls temperature as well as rainfall, affecting the agricultural production and productivity. Therefore, Adaptation and mitigation of agro ecosystems to climate change necessitate adoption of the strategies of sustainable intensification. The latter implies “producing more from less”: more agronomic yield per unit of land area, and input of water, energy, fertilizers, pesticides and gaseous emissions. The large yield gap, difference in agronomic yield of research plots and the national average yield, can be abridged by adoption of the best management practices.
