Strategies for promoting sustainable aquaculture in arid and semi-arid areas

Starvation and malnutrition are one of the most destructive problems faced by the poor and needy in the world. With the world population expected to increase by 9.7 billion by 2050, there are growing concerns about the long-term sustainability of many existing food production systems to meet future needs for food. Aquaculture is one of the important sources of food supply, the development of which is of great importance as an important weapon in the global fight against malnutrition and poverty, especially in developing countries and arid and semi-arid regions of the world. In recent decades, aquaculture has dominated all sectors of livestock production in terms of growth and increasingly contributes to food security, poverty reduction, job creation and sources of income. It is important to follow sustainable development goals to increase aquaculture production. Climate change is currently affecting food security through increasing temperature and decreasing rainfall, especially in arid and semi-arid regions. Food security is a global concern and access to affordable, nutritious, safe and properly cultivated food is one of the most important issues globally. The main emphasis in the development of aquaculture in arid and semi-arid areas is the use of new technologies based on water saving, such as biofloc technology (BFT), integrated multi-trophic aquaculture system (IMTA) and recirculating aquaculture systems (RAS). In this study, the importance of aquaculture as a sustainable source of food production in arid and semi-arid regions is discussed.
