Food-energy-water nexus: Food waste recycling system for energy Полный текст
2022
Siaw, Mathew Nana Kyei | Oduro-Koranteng, Elizabeth Ayaw | Dartey, Yaw Obeng Okofo
A humongous amount of food goes to waste yearly. The use of renewable energy sources is encouraged to reduce global warming. Food waste as a source of energy and water as a food-water-energy nexus has shown to be a viable source of renewable energy. This paper proposes a food waste recycling system that uses a mechanical presser to the extraction of moisture from the food waste with its desiccate being fed to an anaerobic digester to produce biogas. Literature on the topic is reviewed and the benefits and limitations of the system are also discussed.

Water for food systems and nutrition Полный текст

Access to sufficient and clean freshwater is essential for all life. Water is also essential for the functioning of food systems: as a key input into food production, but also in processing and preparation, and as a food itself. Water scarcity and pollution are growing, affecting poorer populations most, and particularly food producers. Malnutrition levels are also on the rise, and this is closely linked to water scarcity. The achievement of Sustainable Development Goals (SDG) 2 and 6 are co-dependent. Solutions for jointly improving food systems and water security outcomes include: (1) strengthening efforts to retain water-based ecosystems and their functions; (2) improving agricultural water management for better diets for all; (3) reducing water and food losses beyond the farmgate; (4) coordinating water with nutrition and health interventions; (5) increasing the environmental sustainability of food systems; (6) explicitly addressing social inequities in water-nutrition linkages; and (7) improving data quality and monitoring for water-food system linkages, drawing on innovations in information and communications technology (ICT). Climate change and other environmental and societal changes make the implementation and scaling of solutions more urgent than ever.

Rabi H. Mohtar | Rabi H. Mohtar | Ali Fares
Globally, water is a bottleneck to food security and, as such, a new approach for water for food is needed. Food insecurity is knocking at every nation's door, including those of the most developed. Moreover, the disruptions in food supply chains that result from continued reliance on a business-as-usual approach of traditional, non-sustainable food and agricultural systems make food insecurity even more vividly present. This article explores the current relationship between food production and water resources. It attempts to better understand how we might reduce the inter-dependencies between food and fresh water by exploring new and alternative sources of water, including improving the efficiencies of green and recycled water.
