  • Offers current data, based on the latest technologies and measurement methods available.
  • Explanations of extreme events and its effects on agriculture are provided in basic scientific terms.

Summary

Despite the current technological advancement, agriculture is still a vital source of livelihood. It is essentially dependent on weather and climate, and adversely affected by extreme events in this respect. Over the past few decades, extreme events such as droughts, floods, storms, tropical cyclones and forest fires have destroyed economic and social infrastructure and at the same time endangered food security. The agricultural sector is affected through the impact on water resources, damage to crops, rangelands and forests, due to incidence of droughts, locust plagues and wildland fires. While natural hazards may not be avoided, the integration of risk assessment and early warnings, with prevention and mitigation measures, can prevent them from becoming disasters. Improved forecast accuracy and mroe focused information on the location, intensity and duration of climate extremes could underpin efforts to implement more effective risk management strategies. This book, based on state of the art knowledge on the science and application of agricultural meteorology needed to better cope with extreme climate events, should be of interest to all organizations and agencies engaged in planning disaster reduction strategies and mitigation of extreme events.
