“…Soil waterlogging is a recurrent phenomenon wherever rainfall is erratic and intense, and the soil drainage capacity is poor. Because maize is a non-wetland crop species of tropical origin, it is highly susceptible to waterlogging at almost all the crop stages, especially before tassel emergence (Zaidi et al 2004 ; Kuang et al 2012 ).…”

Key message Intensive public sector breeding efforts and public-private partnerships have led to the increase in genetic gains, and deployment of elite climate-resilient maize cultivars for the stress-prone environments in the tropics. Abstract Maize (Zea mays L.) plays a critical role in ensuring food and nutritional security, and livelihoods of millions of resource-constrained smallholders. However, maize yields in the tropical rainfed environments are now increasingly vulnerable to various climate-induced stresses, especially drought, heat, waterlogging, salinity, cold, diseases, and insect pests, which often come in combinations to severely impact maize crops. The International Maize and Wheat Improvement Center (CIMMYT), in partnership with several public and private sector institutions, has been intensively engaged over the last four decades in breeding elite tropical maize germplasm with tolerance to key abiotic and biotic stresses, using an extensive managed stress screening network and on-farm testing system. This has led to the successful development and deployment of an array of elite stress-tolerant maize cultivars across sub-Saharan Africa, Asia, and Latin America. Further increasing genetic gains in the tropical maize breeding programs demands judicious integration of doubled haploidy, high-throughput and precise phenotyping, genomics-assisted breeding, breeding data management, and more effective decision support tools. Multi-institutional efforts, especially public–private alliances, are key to ensure that the improved maize varieties effectively reach the climate-vulnerable farming communities in the tropics, including accelerated replacement of old/obsolete varieties.

“…Crop-water relations are important issues in agricultural research. For the benefit of scheduling irrigation and drainage, cropwater production functions (i.e., the quantitative relationships between crop yield and water stress intensity) [50,51] are extensively developed to simulate crop yield responses to various water stress conditions. In this work, the relationships of cotton climatic yield vs. cotton flooding and drought intensity were established, which can be applied to predict regional cotton climate-induced yield.…”

Cotton yield is restricted worldwide by flooding and drought that occur across various growth stages. In this study, cotton flooding and drought in Hubei (a major cotton-production province in China) from 1961 to 2019 were analyzed regarding growth stages through a daily index named the standardized antecedent precipitation evapotranspiration index (SAPEI). In addition, the impacts of flooding and drought on cotton climatic yield were quantified using multiple regression models. The results showed that the temporal trends of cotton flooding and drought intensities were generally smooth, except for an obvious downward trend for cotton drought intensity at the flowering and boll-forming stage. Additionally, cotton drought intensity varied more drastically than that of flooding over the years. Cotton-flooding proneness was much greater than cotton-drought proneness at all growth stages, and the most flooding-prone and drought-prone periods were identified as the flowering and boll-forming stage and the budding stage, respectively. In terms of spatial distribution, northeastern Hubei and southwestern Hubei were most prone to flooding and drought, respectively. The SAPEI-based regression model (R 2 =0.490, p<0.001), obviously outperforming the SPEI-based model (R 2 =0.278, p<0.05), revealed that both cotton flooding and drought exhibited negatively significant effects on cotton climatic yield and that the yield-reducing effect of cotton flooding was much greater than that of drought. Moreover, when growth stages were further considered using regression analysis, only the flowering and boll-forming stage was detected with a significant yield-reducing effect of cotton flooding. In conclusion, the SAPEI can effectively assist in monitoring cotton flooding and drought; cotton flooding, especially during the flowering and boll-forming stage and that occurring in northeastern Hubei, is the key issue for cotton field water management in Hubei.

“…During this month, improvements in climatic suitability based on rainfall were projected on the mid central and southwestern portion of the country such as Not Suitable to Marginal (4.3%), Not Suitable to Moderate (0.1%), from Marginal to Moderate (6.1%), and from Moderate to High (4.68%). The projected increases in rainfall in the country under future climate condition alter the suitability of corn production in the most part of the country because excessive water affects corn at every growth stage (Kuang et al 2012, Zaidi et al 2004). According to Zaidi et al (2004), excessive moisture condition at all physiological stages results to plant mortality, stunted growth, and reduced leaf area and total biomass.…”

“…According to Zaidi et al (2004), excessive moisture condition at all physiological stages results to plant mortality, stunted growth, and reduced leaf area and total biomass. Based on the study of Kuang et al (2012), excess water or flooding during the seedling, jointing, tasseling to silking, and maturity stage results to 25.8-67.1%, 26.1-34.7%, 10.8-25.0%, and 3.1-4.9% reduction in yield, respectively.…”

SAlvAcion A.r., 2017. Mapping spatio-temporal changes in climatic suitability of corn in the Philippines under future climate condition. Quaestiones Geographiceae 36(1), Bogucki Wydownictwo Naukowe, Poznań, pp. 105-120, 11 figs, 5 tables.AbStrAct: This study assessed the spatio-temporal changes in corn climatic suitability in the Philippines under future climate condition. Using extracted climatic data from WorldClim database for the country under baseline and future climate condition, changes in corn suitability was assessed using fuzzy logic approach and published rainfall and temperature requirement of the crop. Based on the data, the large portion of the country will experience increase in monthly total rainfall (88%) while increase in monthly mean and minimum temperature under future climate condition is projected for the entire country. These increases in rainfall and temperature resulted in changes of corn climatic suitability in the country depending on the month and location. On the average, changes in rainfall resulted in reduction (8%) and improvement (6%) in corn suitability while increase in temperature resulted in 5% and 0.4% reduction and improvement, respectively.
