Building Stress Resilience of Cereals under Future Climatic Scenarios: ‘The Case of Maize, Wheat, Rice and Sorghum’
World population is projected to reach 10 billion by 2050 and the phenomenon is expected to cause a surge in demand for food, feed and industrial raw materials. Cereals (i.e., carbohydrate-rich grain crops) are the most widely grown and consumed crops worldwide. All cereals combined provide approximately 56% and 50% of global energy and protein needs, respectively. Maize, wheat, rice, barley and sorghum are the most produced and consumed cereals, globally. These are widely grown across the world from the tropics to the temperate regions. Although efforts are being done by governments, research organizations and academic institutions to increase productivity of these important crops, huge yield deficits still exist. Climate induced biotic (e.g., pests and diseases) as well as abiotic stresses (especially; heat and drought) are widely regarded as the key yield-constraining factors of most cereal crops. Given the contribution of cereals in global food and nutrition security, improvements in productivity of cereal production systems is mandatory if livelihoods are to be guaranteed. This chapter discusses the global production and utilization of four of the major global cereals, limiting factors to their productivity and possible solutions to the production constraints.
