Food security, nutrition, and sustainable agriculture constitute fundamental elements that contribute significantly to the attainment of the United Nations' Sustainable Development Goals (SDGs). These goals are a globally shared blueprint that calls for peace and prosperity for all people and the planet. Focusing on food security and nutrition is directly linked to SDG 2 which seeks to "End hunger, achieve food security and improved nutrition, and promote sustainable agriculture." Beyond SDG 2, these themes also relate to other SDGs such as Goal 3 - Good Health and Well-being, Goal 12 - Responsible Consumption and Production, and Goal 13 - Climate Action. The relationship between sustainable agriculture and these goals is profound; by promoting eco-friendly farming methods, we reduce the environmental footprint, mitigate climate change, and ensure the long-term sustainability of food production systems.
Moreover, sustainable agriculture is vital in fostering biodiversity, improving soil health, and enhancing water use efficiency, which are critical aspects related to Goals 14 and 15 - Life below Water and Life on Land respectively. By safeguarding our ecosystems, we not only ensure food security but also the preservation of the natural environment for future generations. In turn, better nutrition is a conduit to improved health (SDG 3), and it can also influence educational outcomes (SDG 4), given the known links between nutrition and cognitive development.
Furthermore, it is worth noting that the interconnections go beyond these goals. There's an important nexus between sustainable agriculture, food security and issues of poverty (SDG 1), gender equality (SDG 5), clean water and sanitation (SDG 6), and economic growth (SDG 8), among others. Sustainable agriculture creates job opportunities, thus reducing poverty levels. By empowering women in agriculture, we can help achieve gender equality. Proper water and sanitation practices in agriculture can prevent contamination, ensuring clean water and sanitation for all. Therefore, the triad of food security, nutrition, and sustainable agriculture, while being a significant goal in itself, is also a vehicle that drives the achievement of the wider Sustainable Development Goals.
Soil and water salinity and associated problems are a major challenge for global food production. Strategies to cope with salinity include a better understanding of the impacts of temporal and spatial dynamics of salinity on soil water balances vis-à-vis evapotranspiration (ET) and devising optimal irrigation schedules and efficient methods. Both steady state and transient models are now available for predicting salinity effects on reduction of crop growth and means for its optimization.
Background: Fruits and vegetables are an excellent source of nutrients, with numerous health benefits. Most consumers are not meeting the daily recommended intake of fruits and vegetables. Yet, a significant amount of fruits and vegetables that is produced is wasted. There are opportunities to recover the wasted fruits and vegetables for manufacturing value-added products to improve the sustainability of healthy diets and reduce the environmental footprint.
Elucidating relationships between the soil food web, soil processes, and agroecosystem function is a critical step toward a more sustainable agriculture. Soil and crop management practices can alter these relationships, and their effects can persist even after imposing new management practices. In 2005, the Cornell Organic Grain Cropping Systems Experiment was established in central New York. Four cropping systems that varied in fertilizer inputs, tillage practices, and weed control were compared: High Fertility, Low Fertility, Enhanced Weed Management, Reduced Tillage.
