“…For example, Ramirez-Villegas et al (2013) has shown that suitable areas for sorghum could be reduced by 20% over Southern Africa in the next decade. Similar suitability changes have been reported for cassava (Heumann et al, 2011;Jarvis et al, 2012), maize (Nabout et al, 2012;Estes et al, 2013;Holzkämper et al, 2013) and common beans (Ramirez-Cabral et al, 2016;Taba-Morales et al, 2020). Multiple crop suitability under climate change has also been evaluated with these models (Jarvis et al, 2012;Chemura et al, 2020).…”

Changes in Climate Extremes and Their Effect on Maize (Zea mays L.) Suitability Over Southern Africa

Southern Africa has been identified as one of the hotspot areas of climate extremes increasing, at the same time many communities in the region are dependent on rain-fed agriculture, which is vulnerable to these rainfall and temperature extremes. The aim of this study is to understand changes in extreme indices during the agricultural season under climate change and how that affect the modeling of maize suitability in Southern Africa. We analyze the changes in rainfall and its extreme indices (consecutive dry days, heavy rain events and prolonged rainfall events), and temperature and its extreme indices (hot night temperatures, hot day temperatures and frequency of very hot days) from the past (1986–2014) to the future (2036–2064) and integrate these into a maize suitability model. Temperature extremes are projected to increase in both duration and intensity, particularly in the eastern parts of the region. Also, consecutive dry days are projected to increase over larger areas during the agricultural season, while rainfall will be less in sums, heavier in intensity and less prolonged in duration. Including extreme climate indices in maize suitability modeling improves the efficiency of the maize suitability model and shows more severe changes in maize suitability over Southern Africa than using season-long climatic variables. We conclude that changes in climate extremes will increase and complicate the livelihood-climate nexus in Southern Africa in the future, and therefore, a set of comprehensive adaptation options for the agricultural sector are needed. These include the use of heat, drought and high-intensity rainfall tolerant maize varieties, irrigation and/or soil water conservation techniques, and in some cases switching from maize to other crops.

“…In this context, studies have been carried out to determine the suitability of land against climate change for various plants worldwide and in Türkiye. Studies have been carried out worldwide on tomato, bean, sugar beet, carrot, chick pea, cowpea, eggplant, faba bean, grass pea, potato, sweat potato, common bean, broad bean, table potatoes, asparagus, cauliflower, broccoli, kale, white cabbage, celeriac, onions, parsnip, root parsley, leek, beet, red cabbage, lettuce, savoy cabbage, spinach, sweet corn, peas, jerusalem artichoke, leaf parsley, pumpkin, etc., to determine the suitability of land [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. In Türkiye, suitable areas have been determined only for maize, safflower, canola (rape), cotton, wheat, switchgrass [23], and bioenergy crops [24].…”

Climate change is one of the most important problems that needs to be dealt with in Türkiye and worldwide. One of the sectors that will be most affected by climate change is the agriculture sector. For this reason, it is very important to adapt to changing climatic conditions, take the necessary precautions, and ensure sustainability in the agricultural sector today. The land suitability for spinach (Spinacia oleracea L.) cultivation, a vegetable that is rich in nutrients, has never been investigated in Türkiye. Therefore, it is important to investigate the suitability of spinach cultivation areas in Türkiye in the case of possible climatic changes in future years. The most important original value of this research is that three separate climate change prediction models were used, as opposed to using only a single climate change prediction model, to determine the land suitability for spinach cultivation. The aim of this study is to determine the land suitability for spinach in line with possible climate change prediction models and scenarios in Türkiye and its evaluation by comparing it with the current model. To achieve this goal, HADGEM2_ES, CNRM_CM5, and MPI_ESM_LR climate models and RCP 4.5 and RCP8.5 scenarios were used, and land suitability was determined and evaluated with the help of Ecocrop integrated into DIVA-GIS for spinach in Türkiye currently and in the 2050s. The results found that there will be decreases in suitable, very suitable, and excellent areas for spinach cultivation and increases in not-suited, very marginal, and marginal areas. Considering the possible temperature and precipitation changes, it has been observed that the areas in which spinach can be grown in Türkiye in the 2050s will be negatively affected by climate change due to the increasing temperature and decreasing precipitation in general, and solutions are proposed in this study to ensure sustainability.
