Agriculture production is highly dependent on water and increasingly subject to water risks. As a sector, it uses the most water and is also a major water polluter. Improving water management is essential to a sustainable and productive agro-food sector (link).
This article will review some detected problems in food production and consumption. In food production, current issues like the destruction of land ecosystems, overfishing or the generation of high amounts of residues stand out. Some solutions have been described, such as implementing agroecology, improving aquaculture productivity or re-valorising by-products. The main problems in food consumption are food fraud and unhealthy dietary patterns, whose main solutions are standardisation along the food chain and education on healthy lifestyles. In conclusion, the food system should change toward more sustainable practices and behaviours to ensure the subsistence of the present and future generations.
