This book examines the impact of democratic backsliding and populist governments on the public policy process. Drawing on case studies from the USA, Brazil, Hungary, Mexico, Poland, Turkey, and the Philippines, it assesses how elected populist governments have eroded policy capabilities and dismantled state apparatuses responsible for making and implementing policy. The book offers a unique perspective into democratic backsliding through a public policy lens, and considers why, when and how policy processes change as a result of populist governments. Numerous policy issues are analysed throughout the volume, including environmental, health and economic policies. It will appeal to all those interested in public policy, democracy studies, and public administration.

The governance of the water, energy, and food (WEF) nexus is significant in the Arctic, where environmental changes are occurring at an accelerated pace, intensifying resource dynamics and geopolitical implications. Against the backdrop of a rapidly evolving Arctic landscape shaped by the global climate change, melting ice, and resource exploration, the WEF nexus emerges as a vital framework for understanding and addressing the region’s complex resource interdependencies. Nonetheless, legal research in this context is still in its early stages, and, specifically in the context of the Arctic, we did not find any such research. This study assesses a nexus approach to WEF in Arctic’s transdisciplinary and multifaceted environment from an international law perspective to address the intricate dynamics that shape the resilience and security of WEF resources in an increasingly interconnected and accessible Arctic. Our objective in this study is to introduce international law as an overarching network of international rules and principles, legal instruments, and relevant institutions as a starting point to address the WEF governance intricacies in the Arctic, facilitating the harmonization of diverse interests, ensuring equitable access to resources, and promoting sustainable development. We argue that international law constitutes the essential means to address a nexus approach to WEF and its issues and complexities in a transboundary context within the Arctic. By examining existing international legal frameworks applicable to the Arctic and related instruments, policies, journals, and other publications, this paper seeks to canvas how international law is in support of a nexus approach to WEF in this region.

The coastal zone, consisting of one-third country's area, is the most climate-vulnerable region of Bangladesh. The country has invested significantly in coastal zone through the construction and rehabilitation of polders. Despite vast opportunities, land productivity in the polders is very low due to poor water governance and management. To improve in-polder water management, the responsibility of operation and maintenance of the polder water infrastructure has been transferred to Water Management Organizations (WMOs) since 2001. WMOs are currently voluntary organizations but are very important for micro-level agricultural water management. A study was conducted in 2017 and 2018 in a medium saline polder; with a major focus on organizational behaviour: hierarchy in decision-making, transparency, financial accountability, leadership, internal communication, and motivational incentives of the WMOs. The data were collected through a structured questionnaire from 192 respondents of randomly selected eight Water Management Groups (WMGs – the lowest tier of WMOs), out of 40 WMGs of the polder. The results revealed that the WMGs operations are not fully participatory in principle yet. Even the transparency, financial accountability, leadership, and internal communications within WMGs are not strong enough to take the organizational responsibility to address future challenges in food security of the climate-vulnerable polder communities. Improving drainage through efficient water management showed a yield gain of at least 1.5 t/ha in the wet season only. In addition, improved drainage fosters sustainable year-round cropping with high-yielding, high-value and nutrition-rich crops with 2 to 3 times higher productivity than the traditional cropping system. Therefore, investment in water governance particularly in improving drainage in the polders could be a major game-changer in sustaining the food security of the climate-vulnerable polder communities of Bangladesh. The study identified the knowledge gap as a significant concern that demands the need for capacity building of the WMOs.

Land-water transition areas play an important role in the functioning of both aquatic and terrestrial ecosystems. Enhancing habitat complexity and heterogeneity by restoring or adding land–water transition areas to degraded aquatic ecosystems can be effective management to stimulate productivity by lower trophic levels – and hence increase food availability for biota of conservation interest, including fish and birds. Here, we studied whether hydrological connectivity can be used as an environmental indicator (connected or disconnected) for the development trajectories of newly constructed land–water transition areas in shallow lakes. We capitalized on a large-scale restoration project called “Marker Wadden”, which created new land–water transition areas with and without hydrological connectivity in a degraded shallow lake in the Netherlands (Lake Markermeer). We compared how the new areas with and without hydrological connectivity developed with respect to abiotic parameters and biomasses of benthic, pelagic, and emergent macroinvertebrates. In sites disconnected from the open water, water depths became significantly lower than in hydrologically connected sites during summer, likely due to evaporation. In these shallower waters, daytime temperatures and organic matter content of the sediment were higher, while dissolved oxygen concentrations remained sufficient. Therefore, biomasses of benthic macroinvertebrates and emergent insects became higher in the disconnected sites. These lower trophic levels could provide higher food availability for benthivorous and insectivorous birds, while remaining inaccessible to fish. This puts forward that hydrological connectivity (connected or disconnected) can be used as an environmental indicator for aquatic food web development trajectories, and that it regulates relative food availability for fish and birds. Restoring land–water transition areas without hydrological connectivity provides higher biomasses of lower trophic levels, which are only accessible to birds. Restoring areas with hydrological connectivity results in relatively lower biomasses of invertebrates, but these provide food to birds feeding on invertebrates, and fish and fish-eating birds. Creating areas including both types of land–water transition zones, connected and disconnected to open water can benefit fish and birds of both feeding guilds.

The projected increase in demand for food, water, and energy owing to systemic shocks has heightened the need for innovative solutions and integrated resource governance. The Agrovoltaics for Mali and Gambia (APV MaGa) Project, focuses on sustainable electricity production through agrovoltaics' triple land-use system and is leveraged with digital technologies. The project addresses The Gambia’s high food importation gap, growing dependency on fossil fuels for electricity generation, and high electricity tariffs. However, the nascence of agrovoltaics presents a new energy dimension that calls for increased coordination of sectoral policy and management, a domain of WEF nexus governance detached mainly from governance practice. Thus, a policy and institutional foresight of the potential implications of agrovoltaics’ integration is warranted, since Gambia’s decision-making for land, water, energy, and agriculture remains mainly sectoral. A qualitative research design was adopted, using a sample of twenty-eight key informative interviews, policy document analysis, and grey literature. Research findings show that the existing policy frameworks such as ‘Feed-in tariffs for excess RE, renewable energy funds, and capital subsidies can practically accommodate the frame of the agrovoltaics. However, clarification is required on the siting aspect of solar panels within the compartmentalized land policy structures. Institutionally, the Ministry of Energy’s nexus platform allows for technical coordination of agrovoltaics projects. However weak institutional harmonization, technical/financial incapacities, and overriding national interests due to sectoral bias present challenges. Therefore, harmonizing sectoral divergent policy provisions, interests, and prioritization of sustainability concerns will foster the pertinent integration of agrovoltaics for fast expansion.

Water, energy, and food are essential for all humans and require land use. In a land-limited country with high ambitions for solar PV and a growing population, balancing land use for energy and food is necessary to avoid sectorial competition and minimise pressure on land resources. Agrivoltaics, an integrated approach combining energy and food production on the same land, can help to provide clean water, clean and affordable energy, and quality food for the growing population. This innovative approach to the water-energy-food-land nexus (WEFL) has been experimented with and attracted greater research interest and acceptance in many countries, mainly in the North but not so much in Africa. Agrivoltaics is relatively new in West Africa, and minimal research and development have been conducted within the region. As a desk-based study, this paper reviews the WEFL state in Benin and discusses how agrivoltaics could be an asset for current and future WEFL to improve sustainable development in Benin.

The growing demand for sustainable and healthy practices has led to an increased interest in the electrolyzed water (EW) application. This technology has garnered widespread acceptance as a sanitizer within the food industry. It also enhances the nutritional, functional, and sensory properties of food products to improve quality and safety. This review undertakes a comprehensive review of the recent advancements in electrolysis technology, exploring its applications in fruits and meat industry and its impact on nutritional, functional, microbiological, safety, and sensory characteristics. It is concluded that the EW should be considered an essential component of industrial equipment sanitization and food product decontamination by offering antimicrobial benefits and promoting functional component accumulation. Nevertheless, the effectiveness of EW can be compromised by the presence of organic matter and equipment corrosion. Furthermore, it provides a concise overview of EW generation, elucidates the influential factors governing its production, and delineates prospective directions for research and development in this field.

The water–energy–food–ecosystems (WEFE) provide vital resources that are essential to human existence. Exploring synergies and trade-offs in these systems has been of interest in recent years to increase economic gain while sustaining the environment. The Tana-Beles Sub-basin of Ethiopia is challenged by population density, climate change, and ecosystem degradation that requires a WEFE Nexus thinking. To understand the current WEFE nexus interactions in the basin, a systematic review of 102 scientific research articles published from 1991 to 2021 was undertaken. Additionally, the systematic review is complemented by spatial data analysis to identify synergies and trade-offs among the WEFE nexus indicators. The analysis revealed the dominance of food–water–ecosystem interdependencies in WEFE nexus research for the Tana-Beles Sub-basin. This dominance is driven by extensive food production activities, which lead to substantial water abstraction and hydrological alterations to meet the intensive water demands of crop cultivation. Simultaneously, the energy-ecosystem interactions are critical due to excessive biomass utilization that exceeds the biomass production potential of the area. Furthermore, the available vegetation cover of the area is very limited to supplement the growing fuel wood demands, which is exerting extreme land degradation and threatening the ecosystem in the sub-basin. This study identifies gaps in WEFE understanding, highlights specific challenges and opportunities within the basin, and calls for coordinated stakeholder action for sustainable resource management through a Nexus approach.

Addressing complex interactions within water, energy, and food (WEF) resources, innovative tools for in-depth analysis and decision-making are imperative. This study introduces chorematic focus maps (CFMs) as a groundbreaking method to visualize and tackle the WEF nexus’s complexities, focusing specifically on the Danube Delta Biosphere Reserve (DDBR). By merging geospatial analysis with on-site validation, this research reveals intricate interdependencies within the nexus and positions CFMs as an effective tool for stakeholders. This study adopts a methodological approach that focuses on identifying human activities and evaluating their impacts on the WEF nexus, with the goal of developing practical and grounded strategies for managing these essential resources. By testing this approach within the DDBR, the potential for wider application is demonstrated, offering a promising framework for addressing similar socio-environmental challenges across various regions. Future research directions include refining CFMs’ precision and practicality through extended fieldwork and stakeholder engagement, testing the framework’s adaptability across various locations and nexus dynamics. Additionally, incorporating cutting-edge technologies such as machine learning could provide deeper insights and reinforce CFMs’ role in decision support for the WEF nexus. Conclusively, this investigation into the WEF nexus through CFMs emphasizes the critical need for strategies that navigate the complexities of environmental management and resource optimization, marking CFMs as a significant tool for both decision-makers and researchers.
