Abstract/Description: | Global food production needs to be doubled by 50% by the middle of 21st century to ensure the food and nu- tritional security for 9 billion people explicitly in the challenging scenarios such as land degradation, water scarcity and environmental pollution. Climate change is evident worldwide due to exponential rise in atmo- spheric carbon-di-oxide (eCO 2 ) and temperature (eT). It leads to more complexity in achieving the sustainable food security. Grain legumes are the major sources of dietary proteins with multifaceted impact on ecosystem services. Being the C 3 crops climate change (more specifically eCO 2 ) usually has positive impact on physiology and productivity of grain legumes as compared to C 4 cereal crops. Grain legumes can allocate the above ground photosynthates into the below ground parts like roots and nodules resulting improvement in plant biomass, rhi- zospheric activities and higher input (water and nutrients) use efficacy. However, the impact of eT on grain legume is not always favourable. High temperature explicitly in the reproductive phase is extremely deleterious causing flower abortion and abnormal pod filling. Besides, eT impairs the performance of grain legumes because of higher evaporative demand, poor root-microbial association and pest severity. Therefore, both agronomic and genetic interventions must be integrated to raise successful grain legumes and to achieve the targeted yield in the changing climatic conditions. The targeted breeding programmes should be selection of high yielding, biotic stress resistant and abiotic stress tolerant grain legume genotypes that are adapted to eCO 2 and eT conditions. Further, integrating the grain legumes with desirable traits to the food production system might impart resilience towards climate change. In this comprehensive review the impacts of climate change (eCO 2 and eT) on above and below ground crop growth, productivity, water use efficiency and disease-pest severity are thoroughly discussed. Further, climate smart technologies which make grain legumes as a perfect candidate crop in the future climatic condition are also highlighted. |
