Abstract:
Cereals are important crops all over the world being source of food. The primary cereals enjoy the status of staple diet in many countries. Currently, there are many challenges to the production of cereals for the burgeoning population the globe. However, the climate change is one of the major reasons. Growth and development of cereal crops are linked to weather, day length and growing degree days (GDDs) which make them responsive to the specific environments in specific seasons. Global temperature is rising due to human activities such as burning of fossil fuels and clearance of woodlands for building construction. The rise in temperature disrupts crop growth and development. Disturbance mainly causes a shift in phenological development of crops and affects their economic yield. Scientists and farmers adapt to these phenological shifts, in part, by changing sowing time and cultivar shifts which may increase or decrease crop growth duration. Nonetheless, climate warming is a global phenomenon and cannot be avoided. In this scenario, food security can be ensured by improving cereal production through agronomic management, breeding of climate-adapted genotypes and increasing genetic biodiversity. In this study, climate warming, its impact and consequences are discussed with reference to their influences on phenological shifts. Furthermore, how different cereal crops adapt to climate warming by regulating their phenological development is elaborated. Based on the above-mentioned discussion, different management strategies to cope with climate warming are suggested. Such interventions will help the farmers and researchers to change the cropping pattern and cropping systems to minimize the impact of weather variability and climate change impacts.
