ABSTRACT
Drought represents a new kind of natural disaster for human society. Climate change impacts, drought, cyclone, floods, and other natural calamities are critical environmental issues receiving much analysis and discussion. The social development, civilization, agricultural cropping patterns, and settlement development are totally dependent on green nature, water availability, and their management. All types of management are dependent on proper policies and good governance. Soil development and fertility improvement are dependent on the water supply and the quality of surface and ground water storage. In cold climatic regions, the last two decades have witnessed growing water stress, both in terms of scarcity and the deterioration of quality. Similar characteristics have appeared in the tropical and subtropical regions. It has estimated that by 2020, the use and reuse is expected to increase by 40%, and 17% more water will be required for food production to meet the needs of the growing population. It is also indicated that by 2025, 1.8 billion people will be living in regions with absolute water scarcity; about two out of three people in the world could be living under water, agriculture, and natural resource stress. The environmental calamities are extending the rush actions; the drought is one of the regular natural calamities seen in different parts of the world as well in Bangladesh and Brazil. The drought impact is a threat for agricultural food production, and less food production is a result of food and nutritional insecurity. Therefore, sustainable use of agricultural practices, which would also embrace the water, soil, forest, air, oil, gas, and petroleum mining sectors, needs to be considered within a strategic 522management approach regarding food production. The above mentioned approaches are probable factors in the management of urban and rural regions for the protection of landscapes and ecosystems as well as agricultural food production. Primary evaluation indicates that, for an increased utilization of natural resources, which are continuously happening in all over the world, as a result that could be a threat for future food security and the sustainability of natural resources. The use of modern engineering technology for agricultural practices and natural resources requires guidelines within the present drought, water scarcity, and environmentally harsh conditions. The innovation of a modern approach and climate smart agricultural and nutritional policies would be the best solution globally for protecting traditional agro products and ensure food security.
