Water resources, energy, and food are fundamental resources for ensuring human social development. The coordinated development of these contributes to improving the quality environment, promoting harmony between humans nature, achieving economic, social, ecological sustainability. This study utilizes panel data from 30 provinces in China 2003 2020. Using a coupled coordination degree model, coupling Water–Energy–Food (WEF) system is calculated, spatiotemporal evolution network connections WEF analyzed. spatial Durbin model employed investigate spillover effects heterogeneous environmental regulation on system. mechanism used explore pathways through which influences results this demonstrate that index China’s provincial-level has shown steady upward trend, except slight decline few years. Over research period, there been significant improvement regional levels. There large differences level among different regions, with distribution pattern south > north east west. Both formal informal regulations have positive system, as well effects. Formal stronger impact compared regulation.

The water–energy–food–ecosystem nexus in North Africa dryland farming: a multi-criteria analysis of climate-resilient innovations in Morocco

Agricultural and Food Economics, Journal Year: 2024, Volume and Issue: 12(1)

Published: Sept. 5, 2024

Abstract Smallholder farmers, who mostly engage in low-value agriculture the drylands of Northern Africa, were first to have felt effects climate change, with threats their livelihoods and food security. The increasing costs agricultural production, poor water energy infrastructure, loss land due urban expansion, fragmented resource management, unsustainable management practices all contribute this vulnerability change. This highlights urgent need for innovative farming systems. Within framework water–energy–food–ecosystem nexus, paper explores dryland systems, by assessing impact on water, energy, food, ecosystem through stakeholder perception. In work, we aim present a systems approach resilience nexus arid semiarid regions. By using multi-criteria analysis (MCA) approach, study—which focuses Fès–Meknès region Morocco—involves local actors help researchers identify key variables order assist farmers adaptation findings revealed different priorities between other stakeholders regarding adoption innovations. Farmers prioritize innovations that guarantee higher profitability more market opportunities, such as integrating olive trees cereal crops, highlighting importance sustainable income sources. Meanwhile, stakeholders, researchers, engineers, government officials, agribusiness entrepreneurs, emphasize high use efficiency, which is crucial areas: instance, rainwater harvesting or drought-resistant crop varieties directly address conservation. But doing so they are overlooking broader aspects within nexus.

Assessing the Coordination and Spatial Equilibrium of Water, Energy, and Food Systems for Regional Socio-Economic Growth in the Ili River Valley, China

Agronomy, Journal Year: 2024, Volume and Issue: 14(9), P. 2037 - 2037

Published: Sept. 6, 2024

Water resources, energy, and food are fundamental resources for high-quality regional development. In the process of rapid economic growth, integrating utilization these has become a critical challenge achieving development in Ili River Valley. To explore coordinated status water, (W-E-F) Valley, we constructed comprehensive evaluation indicator system W-E-F system, calculated analyzed level, coupling coordination degree, spatial equilibrium from 2008 to 2020. The results indicate that indicators Valley exhibited an overall upward trend, indicating is moving positive direction. Among them, water subsystem’s showed trend but fluctuated significantly during study period, with excessive proportion agricultural consumption being key factor affecting its Furthermore, energy subsystem slight downward constraints on subsystems. Agricultural surface pollution industrial waste primary factors limiting Meanwhile, due significant attention governments at all levels, been developed rapidly, showing which shows region actively promoting production capacity enhancement initiatives. Additionally, degree remained state coupling, average value between 0.7 1.0, high each resource affects constrains other two. transitioned through phases near coordination, good moderate counties cities tendency evolve towards potential further coordination. subsystems, highest (0.78) smallest disparities, while demonstrated lowest (0.40) largest disparities.
