Application of the Water-Energy-Food Nexus system is essential for addressing Water-Energy-Food Security and Environmental Protection in urban agricultural areas. However, there is currently no standardized framework for measuring and comparing sustainability indicators in these areas using the WEF Nexus practices. This study proposes sustainability measurement indicators to evaluate the WEF Nexus sustainability. The Analytical Hierarchy Process (AHP) was employed to identify the most crucial indicators for policymakers. The WEF nexus sustainability indicators were selected based on three dimensions of sustainability: social, environmental, and economic. The study focused on Varamin, a semi-arid city in Tehran that serves as a center for urban agriculture. Research results indicate that water-related components are crucial in arid and semi-arid regions. Based on the environmental sustainability indicators, pollution prevention, with a priority of 52.8%, is a critical component of sustainability. Finally, several key indicators are recommended for decision-makers to address sustainability. Allocating national budgets to create environmental policies and increasing public education on environmental issues are two priorities for achieving sustainability goals. However, future studies should utilize the Analytic Network Process (ANP), which enables interdependencies among decision components, as the AHP approach has some limitations. [ABSTRACT FROM AUTHOR]

This study seeks to investigate how natural resources rents impact environmental sustainability measured by CO2 emissions and PM2.5 air pollution in Brazil, Russia, India, China, and South Africa (BRICS) economies from 1995 to 2019. To enhance robust policy implications, natural resources are decomposed into disaggregated (coal, gas, oil, forest, and mineral rents) and aggregated (total natural resources rents) indicators. Besides, the intervening roles of affluence, urbanization, and green policies vectoring green technological innovation, green finance, green energy, and waste management within the theoretical underpinning of STIRPAT model are considered. The empirical verification is anchored on second-generation estimators entailing Common Correlated Effects Mean Group, Augmented Mean Group, and Panel Quantile Regression. Similarly, Fully Modified OLS is employed to gauge the country-specific effects amidst varying robustness analyses. The fallouts from the analyses reveal that natural resources rents inhibit the attainments of environmental sustainability in BRICS economies by positively driving CO2 emissions and PM2.5 air pollution. Conversely, green policies are observed to substantially drive environmental sustainability by mitigating both pollutants whereas affluence and urbanization escalate them. The distributional effects from Panel Quantile Regression and Fully Modified OLS corroborate the main findings divergently. Additionally, two channels of causality, including unidirectional and bidirectional nexuses, are apparent from the estimated models. Policy measures are suggested based on the empirical findings.

Environmental sustainability has been a key policy goal of the European Union (EU), particularly under recent EU Cohesion Policy strategic frameworks. This paper contributes to the analysis of the relevance of EU Cohesion Policy-related environmental sustainability investments, by assessing the impacts of the Operational Programme for Sustainability and Use of Resources (POSEUR 2014–2020), in the Portuguese North NUTS II. In detail, the impact scores of the following five analytical dimensions related to this programme were obtained: (i) low-emissions economy, (ii) adaptation to climate change, (iii) risk prevention and management, (iv) environmental protection and (v) resource efficiency. The analysis was supported by a territorial impact assessment methodology (TARGET_TIA) which was complemented by an online analytic geographic information system (GIS) policy evaluation platform (Impact-WEB_GIS). The results showed that the POSEUR's regional implementation efficiency fell short of the stakeholders' expectations. This can be explained by factors such as the obstacles posed by the prior underdeveloped infrastructural conditions, coupled with the panorama created by the Covid-19 outbreak. Nonetheless, the risk prevention and management dimension had a solid positive impact score that reflected the efficacy of POSEUR in tackling environmental threats, mostly in rural ecosystems.
