Global warming - Impact of climate change on Agriculture business

Global warming- Impact of climate change on Agriculture business In India

More floods, frequent droughts and forest fires, decrease in agricultural and aqua cultural productivity, displacement of coastal dwellers by sea level rise and intense tropical cyclones, and the degradation of mangroves may be some of the likely consequences of climate change in Asia.
Such consequences could considerably affect the food supply and access through their direct and indirect effects on crops, soils, livestock, fisheries and pests. Increase in atmospheric CO2 promotes the growth and productivity of C3 OOW photosynthetic activity) plants. On the other hand increase in temperature, can reduce crop duration, increase crop respiration rates, affect the equilibrium between crops and pests, hasten nutrient mineralisation in soils, decrease fertilizer use inefficiencies, and increase evapo-transpiration among others. Uncertainty in precipitation causing droughts and floods has been responsible for many famines, rural poverty and migration despite development of impressive irrigation potentials. These environmental changes, particularly temperature increase and sea level rise, could also affect fisheries directly and indirectly through changes in the availability of feed. Similarly, by increased temperatures the changes in fodder and water availability may affect production of meat and milk.
Indirectly, there may be considerable impact on agricultural land use due to snow melt, availability of irrigation, frequency and intensity of inter- and intra-seasonal droughts and floods, soil organic matter transformations, soil erosion, decline in arable areas (due to submergence of coastal lands), and availability of energy. All these changes would have tremendous impact on agricultural production and, hence, on the food security of any region. Several important socio-economic determinants of food supply such as government policies, capital availability, prices and returns, infrastructure, land reforms, and inter- and international trade are also expected to be influenced and altered by environmental changes.



Indian Farmer effected by global warming

India’s richest State,
Maharashtra, had seen over 50,000 farmer suicides between 1995-2012 along with Karnataka, Andhra Pradesh, Madhya Pradesh and
Chattisgarh it recorded well over two-thirds of the total farmer suicides due to global warming (Climate change) .
