A review of literature on climate change and its impacts on agriculture productivity

This paper provides a comprehensive review of various reports, articles documents and papers literature related to the assessment of climate change impacts on crop productivity, and will focus on how climate change and affects agriculture productivity. Agricultural practice is affected by climate changes because of its direct dependence on climatic changes. There are two methods of relationships between agriculture and climate change and has huge significance especially for developing and underdeveloped or low‐income countries, who are largely dependent on agriculture for subsistence and their lack of infrastructure for adaptation as compared with developed countries. Geographically high‐latitude areas with already existence of low temperature, by virtue of increasing temperature due to climate changes, could allow for the longer growing season. Agricultural fields are affected by the emission of GHG such as carbon dioxide, nitrous oxide, and methane. Gasses have an effect on climate through the discharge of greenhouse gasses. Emissions mostly come from the tillage practices, fossil fuels, fertilized agricultural soils, and farm animal's manure in a huge amount and affected the agriculture sector. On the contrary, agriculture could be a solution for climate change by reducing emission and implementation of mitigation and adaptation actions widely. It will happen with the assistance of best management practices such as agroforestry practice, organic farming, rainwater harvesting, irrigation planning, and manure management.
