An Overview of Climate Change and Its Impact on Crop Productivity | Chapter 3 | Recent Advances in Science and Technology Research Vol. 6

 One of the defining challenges of our time is minimal change. This climate change is triggered by natural and anthropogenic causes and has a significant effect on the availability of different resources on the planet. The natural being is demonstrated by multiple methods due to the frequent tidal pulls exerted by the celestial bodies on the atmosphere of the planet and the improved one's are due to changes in the environment across past and present. Changes in the biosphere, biodiversity and natural resources adversely affect human health and quality of life. India is expected to experience warming above global levels in the 21st century. With more warmth in the winters than in summers, India will also begin to experience more seasonal variation in temperature. In recent years, with colder night temperatures and hotter days, the longevity of heat waves across India has spread, and this pattern is expected to continue. The average change in temperature is expected to be 2.33 ° C- 4.78 ° C with A doubling in concentrations of CO2. These heat waves will contribute to an increase in summer monsoon precipitation variability, resulting in a dramatic impact on India's agriculture sector. A steady increase in the concentration and temperature of carbon dioxide ( CO2) across the globe is expected by climate models. Local weather conditions, such as rain, temperature, sunshine and wind, can increase food production as long as plant diseases can be managed in conjunction with locally adapted plant varieties, cropping systems and soil conditions. The most recent Intergovernmental Panel on Climate Change (IPCC) study shows that, relative to 1980-1999 temperatures, the average global temperature is expected to rise between 1.1 and 6.4 ° C by 2090-2099, with the most likely increase being between 1.8 and 4.0 ° C. Climate change will also affect global warming Precipitation trends, which affect both the amount of precipitation received and the distribution of precipitation in several locations over the course of an average year. With this climate change, impacts on the ecosystem, including the soil, can occur. Further analysis of soil-climate interactions in a changing environment is therefore important for resolving potential questions about food security. To resolve this, by inter-cropping and appropriate cropping systems / rotations / land use, we must increase crop diversity; implement land / water conservation agriculture methods suitable for varied agro-climates, balanced use of biocides / chemicals; increase carbon fixation in the soil by growing deep-rooted crops to minimise carbon foot printing; use water wisely: more crop / unit of water; use .
