This study focused on analysis of global food demand and supply situation by 2030 and 2050, water demand-availability, impact of climate change on world water resource, food security and desalination challenges and development opportunities. The population of the world will be 8.6 billion in 2030 and 9.8 billion in 2050; Africa will be the major contributor. World cereal equivalent (CE) food demand is projected to be around 10,094 million tons in 2030 and 14,886 million tons in 2050, while its production is projected to be 10,120 million tons in 2030 and 15,970 million tons in 2050 having a marginal surplus. India and China are capturing large share of global food demand. The developing country will demand more animal origin foods due to income growth in the future. The growth rate of world demand for cereals will decline till 2050. Global water demand is projected to increase by 55% between 2000 and 2050 from 3500 to 5425 km3. Evidence showed that climate change will have adverse impact on world water resources and food production with high degree of regional variability and scarcity. A number of options are suggested for development of global water resource and food production.

This book chapter provides an insight into the synthesis of climate change vulnerabilities across various regions of the globe, recent trends, issues and prospects of climate smart agribusiness, the skill, efficiency and sustainable management practices of small and medium enterprises (SMEs) of the globe in the context of climate change, addressing the needs of emerging markets, industries and regional trades through a transformation with development in the areas of technology, value chains, management of environmental and social risk in the supply chains, compliance of food quality and safety regulations, market linkages of smallholders, corporate social responsibility and institutional development. There is a growing concern on food safety regulation and certification as part of sustainable management practices that firms and industries should cope. Sustainable management practices in business prove to be more profitable as they tend to adapt and grow with the changing markets, providing a competitive advantage over other firms.
