Abstract
Climate-smart agriculture is currently gaining attention at the global level for sustainable food production and ensuring food security in a changing climate. Climate change is a major threat to agricultural systems by reducing agricultural productivity and affecting food security. Climate-smart agriculture is a practice that has proved helpful in mitigation and adaptation to changing climate, enhancement of agricultural productivity, incorporation of resilience, and reduction of greenhouse gas emissions. In this review, we have highlighted the role of different practices i.e. Plant Breeding (Crop Wild Relatives, Shuttle breeding, Genomics Selection, Genome-Wide Association Studies, Genome Editing, and Double Haploid Breeding), biotechnological approaches (Genome editing and Genetic engineering) and sensor-based precision agriculture technologies for real data about soil and crops which are helpful in changing climate scenarios. Agroforestry, crop rotation, crop diversification, laser leveling, and other advanced agronomic approaches for enhancing soil organic matter, and water holding and retention capacity of soil may lower the cost and increase food and agricultural productivity, eventually increasing farmer’s income. Governments and scientists should create awareness among people about climate change and its impacts and should also devise ways to mitigate them, keeping in view the above-mentioned techniques. Adoption of climate-smart practices by the farmer community will help in reducing the negative impacts of climate change on agriculture to achieve sustainable food production.
