“…Recently, Kawaye and Hutchinson (2021) indicated an increase in sweet potato yield in Malawi, and they declared that sweet potato is a food security crop and can protect rural society in the context of climate change. Pushpalatha et al (2022) predicted the possible impact of climate change on the yield of sweet potato in India. The yield predictions of sweet potato using the WOFOST crop model indicated a percentage change in the yield of −32% to 14% and −38% to 13% in the future for the medium and high emission scenarios, SSPs‐4.5 and 8.5, which is less compared to that of the predicted yield reductions of rice and potato in India (Figure 6).…”

“…Their analysis indicates higher suitability of sweet potato in the tested region with probability values (suitability indicator) ranging from 0.4 to 0.9. Being sweet potato has the same crop duration as that of rice, the primary food crop, it proved to be superior to rice in terms of its yield changes in the future and per hectare productivity (Pushpalatha et al, 2022). It can be recommended to ensure food availability in the rural tribal areas and developing countries.…”

Sweet potato is one of the important tropical tuber crops across the world. This review analyzes the studies on the climate resilience of sweet potato to various environmental parameters, the impact of climate change on its yield, and geographical suitability to exploit more about this crop and find out the knowledge gap in its existing research. Drought tolerance studies indicate the suitability of sweet potato in drought‐prone areas in terms of their survival rate, and their leaves can tolerate up to a wilting point of −1.3 MPa. The optimum night and daytime temperatures for sweet potato are 18°C and 28°C. There are 82 crop varieties available globally with heat‐stress tolerance without compromising the yield. The elevated atmospheric CO2 enhanced the growth and yield of sweet potato and increased the water use efficiency. The salinity tolerance of sweet potato is observed as 11 dS m−1, and it is superior to other major food crops. Sweet potato's ozone tolerance is higher than other crops (59 ppb). The impact studies on crop yield and geographical suitability also recommend its superiority to other major food crops with similar crop duration. As an outcome of this study, further research is needed to explore this crop as sweet potato can substitute for major food grain crops in developing countries regarding food, feed, medicine, and fuel. Research on value‐added products and their marketing is another area that needs immediate attention. Studies must exploit sweet potato leaves to ensure nutritional security in developing countries. The researchers also need to focus on developing climate‐resilient varieties to ensure a continuous supply of planting materials to needy people to ensure food security. This review also demands more studies on the modeling of sweet potato worldwide to issue crop yield forecasts and monitor the spatial distribution of its major pests worldwide.

“…The yield reduction may result due to < 20% soil moisture availability in sweet potato while for cassava it was a 28-42% decrease in yield in drought-like situations (Ramanujam, 1990). Pushpalatha et al, (2021) carried out a detailed study on tuber crops by using the LARS weather generator to derive future climatic conditions for 2030, 2050 and 2070. The predicted results differ for different locations.…”

The impacts of an increase in carbon dioxide concentration, temperature and precipitation on physiology, yield and biochemical contents of horticulture crops including its mitigation measures are evident globally. This study mainly focuses on South-East Asia and Africa. We have reviewed crop-wise published literature mainly from 2000-2021 regarding the impacts of rising carbon dioxide concentration, temperature and precipitation on horticulture. Visible phenophase changes in horticultural crops such as budburst, leaf initiation, flowering, fruiting, seedling and the overall development stages of the crops are evident from the available literature. The prevalence of many diseases like blight, mildew, abaca, black sigatoka and Pierce’s disease are the results of climate change. Changes in the biochemical content of the horticulture crops such as tannins, flavonol, alcohol level, acidic content, starch, amino acids, lipids, chloroplasts, sugar, organic acids and antioxidants were observed. The recommended mitigation measures throughout the literature are delayed sowing dates, efficient seed varieties, controlled fertilizer use, soil moisture conservation and other biotechnological measures. Salinity, moisture and environmental stress-tolerant crops need to develop for better management of climate change. Breeding of short-duration and heat-tolerant varieties, vulnerability quantification and early warning disease forecasting are some of the important research areas.
