Effect of Climate Change on Crop Productivity

Abstract

Climatic conditions have been changed drastically, which has become a big challenge to sustain agricultural production. Stagnation in production has been observed in the recent past due to different types of biotic and abiotic stresses. The present available varieties do not have resilience to climate change. To sustain the productivity and minimize the yield losses, the best way is to develop climate resilient cultivars, which can produce in abundance even under abrupt climate changes in a sustainable manner. For achieving this, a better understanding of crop response to the newly developed techniques is also required in order to satisfy the needs of the growing population. Further, improving the resilience of food production and minimizing risks against weather variability are essential for agriculture that can be achieved by broadening the genetic base of the varieties through introducing virgin germplasm as potential sources of genes for ensuring food security and sustainability in agriculture in developing countries and protecting natural resources.
