Global Warming - Causes, Impacts and Mitigation Strategies in Agriculture | Current Journal of Appli
Global warming - a new global challenge in front of agricultural scientists, affecting almost all the climatic parameters involving air temperature and rainfall intensity and distributions. Elevated levels of greenhouse gases (GHGs) viz. carbon dioxide, methane, nitrous oxide etc. are only because of faulty agricultural practices viz. intensive tilling, burning of crop residues, which further adversely affecting both land and water productivity. As per one projection that global surface air temperatures may increase by 4.0–5.8°C in upcoming few decades which offset the likely benefits of increasing atmospheric concentrations of carbon dioxide on crop plants. Over space and time, new environmental conditions created which might be responsible for frequent droughts, higher temperatures, flooding, salinity, increased carbon dioxide levels, rise in sea-level, irregular rainfall patterns and shifting of pest dynamics etc. Therefore, global warming cycle needs to break down through forestation, using crop residues on soil as mulch or in soils as biochar instead of burning, and adopting certain agricultural practices or developing new plant cultivars which response to CO2 under higher temperature conditions etc which helps to reduces rather mitigate the adverse effects of the global warming. Further, changes in diets, minimum tillage operations and reductions in food wastage will also serve the purpose. The present review highlighted the crucial reasons for global warming, its impacts on agriculture and finally on mitigation strategies, which helps to improve the agricultural productivity and finally livelihoods of the farmers.
