Delineating suitable zones for solar-based groundwater exploitation using multi-criteria analysis: A techno-economic assessment for meeting sustainable development goals (SDGs)

While several articles have focused on determining a suitability map for groundwater exploitation by assigning weights to different thematic layers, this technique suffers from a lack of worldwide application because it focuses on the features of a specific region (terrain features, vegetation, and climate) during the investigation. To overcome this drawback, we expanded the evaluation method of groundwater exploitation by integrating the region characteristics and topography with the three pillars of sustainability outlined by the SDGs agenda. Seven thematic layers, reflecting the economic and technical characteristics of El-Saloum depression, Egypt, were prepared to develop a solar energy-based groundwater suitability map. It was depicted that about 11.5%, 29.3%, and 44.0% of the total depression were classified into “Most’, “Moderate”, and “Marginal” suitable locations, respectively. Based on the sensitivity analysis, the southeastern zone of the depression emerged as the most suitable site for solar-groundwater utilization due to its low salinity (<5000 ppm), reasonable groundwater depths (less than 50 m), and land availability (undeveloped regions). Substituting a diesel power system (DPS) with a photovoltaic system (PVS) in groundwater pumping and/or reverse osmosis (RO) desalination would reduce 1.2 kg CO2/kWh and maintain a payback period of 6.4 years with a cost of energy (COE) of ∼0.25 US$/kWh. Applying PVS for groundwater management could fulfill about 25.0%, 37.5%, 40.0%, and 20.0% of sustainable development goals (SDGs) 2 “Zero hunger”, 6 “Clean water and sanitation”, 7 “Affordable and clean energy”, 13 “Climate action”. The achievement of these SDGs was equivalent to 22.7%, 15.4%, and 13.2% of the environmental, economic, and social pillars of sustainability, respectively. Consequently, the study's findings are crucial for stakeholders and policymakers involved in the sustainable management of groundwater resources within the SDGs umbrella.

Decentralising Climate Governance in the Global South: Lessons from Itezhi-Tezhi and the Kafue Wetlands, Zambia

This article discusses the challenges of decentralising climate governance in the Global South in the context of intensifying climate change. Using qualitative methods of data collection and analysis, we interviewed a total of 112 participants who participated in the study, including traditional leaders, ward councillors, subject-matter experts, government officials and members of the public who took part in focus group discussions. Our results show that devolution, delegation, deconcentration and privatisation have been used as strategies for decentralising climate action in the Itezhi-Tezhi District. However, these methods of decentralisation are affected by several factors, including unclear rules for elected and appointed leaders, which influence the devolution of decision-making responsibilities at the local government level. Regarding delegation, decentralising climate governance is affected by inadequate public participation, particularly in the design and execution of climate initiatives in the Kafue wetlands. Furthermore, this article shows that deconcentration is likely to affect climate governance because the national government has not deconcentrated the units for climate governance from the line ministry to the local authority. Privatisation, which has been an effective way of decentralising climate governance in the Kafue wetlands, has also been problematic due to inadequate community participation. These challenges and opportunities serve as lessons for building resilience in effective decentralised climate governance in the Kafue wetlands. This article adds to the ongoing discourse on the efficacy of decentralising climate governance in the Global South and offers valuable insights for future research in this genre of academic inquiry in Sub-Saharan Africa.

Is personal income associated with attitudes towards climate change risk? A moderated mediation analysis for the UK from 2009 to 2020

AbstractThis study investigates the effect of personal income on attitudes towards climate change risk, considering the mediator of responsibility attribution (RA) for climate change and the moderator of educational attainment. Using a latent growth curve model applied to data from the UK Household Longitudinal Study dataset from 2009 to 2020, this study indicated that personal income growth heightens the likelihood of expressing concern about climate change while reducing the propensity for holding sceptical or paradoxical attitudes over time. Attributing climate change to personal behaviour mediated the income‐attitude relationship. Significant differences in the mediation effect were observed between individuals who had received a university education and those who had not, even after controlling for covariates such as age, sex, political affiliation and employment status. These findings suggest that climate campaign emphasising RA can address attitude disparities across income and education strata, further promoting sustainable climate action and mitigation.

Navigating climate change complexity and deep uncertainty: approach for building socio-ecological resilience using qualitative dynamic simulation

The consequences of climate change on different sectors of society are interrelated. The threats posed by rising global temperatures, intensifying extreme weather events, and shifting climatic patterns are becoming increasingly evident all around the world. Policymakers face the daunting task of assessing climate change risks, encompassing impacts and response strategies, to guide sustainability transformations. In this study, we introduce a four-step qualitative Decision Making Under Deep Uncertainty (DMDU) approach in the context of Climate Change Impact Assessments (CCIA). Our goal is to enhance the integration of CCIA into spatial planning, particularly in the Global South, using qualitative system dynamics simulation. Emphasizing the value of qualitative DMDU, we explore vulnerability and resilience through a lens of multi-sectoral and multi-scalar socio-ecological processes. We exemplify our approach by applying CCIA to the coastal zone of Yucatán, Mexico, accounting for social and environmental heterogeneity across the four Regions in which it is administered. Results identify the optimal allocation of climate change mitigation and adaptation policies to address specified resilience in each Region, all of which are required to achieve the overall resilience of the coastal zone. We argue that our qualitative DMDU approach provides an analytical platform to address the trade-offs inherent in the ranking of multiple vulnerabilities related to achieving general resilience.

Recife park city: the role of the Recife local climate action plan and the Pernambuco decarbonization plan

This article explores the convergence between Recife and Pernambuco's climate plans and the "Recife Park City" vision. The objectives include the analysis of the goals of the Recife Local Climate Action Plan, the investigation of the guidelines of the Pernambuco Decarbonization Plan in relation to the urban context of Recife and the evaluation of the initiatives of the Recife Park City Project in accordance with local climate objectives and regional. The methodology of the research will be bibliographical review, together with documentary analysis of these plans. We address the intersection between urban sustainability, climate resilience and development, providing valuable insights to promote more sustainable urban practices, respecting the specific environmental and social characteristics of the region. Understanding these strategies is crucial to guide public policies and urban practices towards a more sustainable and environmentally conscious future. According to research, climate plans reflect a comprehensive commitment to sustainable urban development, highlighting the importance of social inclusion, active mobility, cultural identity and environmental conservation to ensure a resilient and equitable future.

Climate change and migration: A review and new framework for analysis

AbstractThis article presents a new interpretive framework for understanding the implications of climate change for migration, and reviews and reflects on existing evidence and research gaps in light of this framework. Most existing climate‐migration research is heavily environment‐centric, even when acknowledging the importance of contextual or intervening factors. In contrast, the framework proposed here considers five different pathways through which climate change is affecting, or might affect, migration: short‐term shocks, long‐term climatic and related changes, environmental “pull” factors, climate adaptation and mitigation measures, and perceptions and narratives. In reviewing the existing evidence relating to each of these pathways, the paper finds among other things that short‐term shocks may simultaneously increase and reduce migration; that the evidence on long‐term trends provides a weak basis for understanding future dynamics; and that more attention needs to be paid to the other three pathways, by researchers and policymakers alike. Overall, the proposed framework and associated evidence review suggest a different and broader understanding of the migration implications of climate change from that outlined in the IPCC's most recent assessment, or in many existing reviews.This article is categorized under: Climate and Development Knowledge and Action in Development

How do we reinforce climate action?

AbstractHumanity has a shrinking window to drastically reduce greenhouse gas emissions, yet climate action is still lacking on both individual and policy levels. We argue that this is because behavioral interventions have largely neglected the basic principles of operant conditioning as one set of tools to promote collective climate action. In this perspective, we propose an operant conditioning framework that uses rewards and punishments to shape transportation, food, waste, housing, and civic actions. This framework highlights the value of reinforcement in encouraging the switch to low-emission behavior, while also considering the benefit of decreasing high-emission behavior to expedite the transition. This approach also helps explain positive and negative spillovers from behavioral interventions. This paper provides a recipe to design individual-level and system-level interventions to generate and sustain low-emission behavior to help achieve net zero emissions.

Toward sustainable climate action in advanced economies: Linking information communication technology, technological innovation, economic complexity, and ecological footprint

AbstractInformation and communication technology (ICT), technological innovation, and renewable energy (REN) consumption have been proffered as solutions to the recent environmental tragedies in developed countries. In recent times, ICT diffusion and technological innovation have improved in G7 countries, but the same cannot be said of REN consumption. As such, this study examines the link between ICT, economic complexity, technological innovation, REN, and ecological footprint (EF) for G7 countries over the period 1990–2020. We use three variables (fixed telephone subscriptions [FTS], mobile cellular subscriptions [MCS], and individuals using the internet [IUI]) to represent ICT. The presence of cross‐sectional dependence guides the use of second‐generation econometric methods for slope heterogeneity, unit root, cointegration, and parameter estimation. The augment mean group (AMG) estimator and panel OLS techniques are applied to complement the method of moment quantile regression (MM‐QR) approach. The MM‐QR results suggest that REN consumption and technological innovation impede the EF across all quantile levels (0.1–0.9), whereas economic growth and economic complexity augment the EF in G7 countries. The ICT variables have heterogeneous effects on the EF, suggesting that the impact of ICT on the EF depends on the estimation techniques and proxy for the variable. In line with these outcomes, public policies directed toward funding technological innovation projects are recommended. The funding should specifically focus on environmentally friendly technologies that can guarantee complementarity between reduced environmental damage and increased economic growth.

Dynamics of energy transition and climate actions on sustainable cities: A cross country comparison of East Asia and Pacific

AbstractMassive energy consumption and poor regulatory framework in urban areas have created environmental slums and are a serious threat to sustainability. East Asian and Pacific economies are vulnerable to climate crises and striving for sustainability by transition to green energy and taking climate initiatives. In the past, no study has explored the effectiveness of energy transitions and climate actions in the context of East Asia and Pacific. To understand the effectiveness of these efforts, this study has been planned and executed to examine the impact of energy transition and climate actions, along with emissions from residential and commercial buildings, per capita income, and effective governance, on sustainable cities and communities in East Asia and the Pacific region. The study utilizes panel data of six high‐income countries and 11 lower‐middle and upper‐middle income countries from 2000 to 2022 for comparative empirical analysis. Empirical analysis is performed using truncated regression due to the nature of the data. The study found that energy transition, climate actions, and governance effectiveness increase the sustainability of cities and communities. However, emissions from residential buildings and per capita income adversely affect the sustainability of cities and communities. Furthermore, the dynamics of energy transition and climate change vary according to the income classifications of East Asian and Pacific countries. Energy transition and emissions showed a higher impact in HICs, while climate actions were more resilient in lower‐middle and upper‐middle income countries. These findings emphasize the transition to clean and green energy, prompt climate policy actions, and effective governance to ensure sustainability in East Asian and Pacific cities and communities.

Carbon finance and funding for forest sector climate solutions: a review and synthesis of the principles, policies, and practices

The question of funding necessary climate actions, including those in the forest sector, to drastically reduce greenhouse gas (GHG) emissions and global warming, is important to both national governments and international agencies. The objective of this paper is to address this question by reviewing and synthesizing the economic principles associated with reducing GHG emissions, the pricing mechanisms used to achieve that goal, and the diverse practices of climate finance. Included in the carbon pricing mechanisms and practices are carbon tax, compliance and voluntary emission trading, internal pricing, and funding via issuing bonds or mobilizing public budgetary resources. Then, it proceeds to describe the roles that public and private organizations can play and have played in supporting emission reduction and removal, which serves as a vital backdrop for examining current states and relative costs of forest sector initiatives. Overall, as reported by the World Bank, only about 23% of global GHG emissions are subject to any explicit price, and 75% of the emissions that are subject to a price are charged less than $10 per tCO2e. Market-based forest finance and international support for reducing emissions from deforestation and forest degradation have accounted for a small fraction of the total spent on climate mitigation and adaptation. Further, the more recent developments in carbon pricing and funding remain slow and disappointing. Without the right scale of green finance at the right time, however, it will be difficult to achieve the needed energy and economic transformation.

Local Climate Action Planning – The Land Use Perspective

For more than thirty years, municipalities across the United States have created Climate Action Plans (CAPs) to address the consequences of climate change within their communities. Scholars have scrutinized the efficacy of local CAPs since their inception, alleging that many hold nothing more than abstract and visionary statements. Indeed, early CAPs often provided detailed plans but lacked corresponding accountability or metrics for bringing those plans to fruition. However, more recent CAPs have sought to ground their aspirations in land use law by integrating the CAPs into comprehensive plans, amending zoning codes to meet urban agriculture goals, and even providing expedited zoning procedures for CAP-compliant developers.

The Complexities of SDGs Goal 5 and 13 in ASEAN Region: A Comparative Study between Balinese and Cambodian Women Campaign on Climate Action

Women tend to be objects and victims of climate change impact. The International Union for Conservation of Nature (IUCN) 2020 found that gender-based violence was aligned with climate and environmental crises in various developing countries. In addition, 9.9 women were affected heavily by natural disasters in Indonesia (BPS, 2017). Meanwhile, only 20% of women's leadership constitutes the entire energy sector (WEF, 2022). Another important statement from the IPCC (2022) said that women (particularly pregnant women) became highly impacted by the climate crisis. The Assessment Report on the State of Gender Equality and Climate Change in ASEAN (2022) built evidence on the importance of recognising women’s roles in climate action in ASEAN countries. In light of this background, this paper will analyse the critical complexities of ASEAN women's leadership towards climate action in order to evaluating the implementation of SDGs goal 5 and 13. To have further deep analysis, this paper will explore the case study of Balinese and Cambodian women who have best practices of climate action, locally, nationally and globally, which also enhance ASEAN countries' commitment to SDGs. Some of the best practices in Cambodia include a Renewable Energy (RE) programme that actively engages with and promotes women-led energy enterprises by implementing “The Smoke-Free Village” approach and training women as champions for gender-transformative Disaster Risk Reduction (DRR). Meanwhile, in Bali, Balinese women play an important role in climate action by establishing the Bali Women Climate Entrepreneur Project which encourages 10 start-ups to join the program and many other best practices to be explored further. As a methodology, the best practices of women leadership in both countries will be collected through literature reviews, interviews, statistics from the Balinese and Cambodia government/SDGs centres, and other relevant documents’ review. From those sources, this paper is expected to be the guide to mapping women leadership in climate action and also become a guide on how to develop effective communication for women in the ASEAN region on climate change.

Assessing the impact of climate action mitigation strategies from livestock production: A review – Solution for greenhouse gases mitigation

Abstract The main sources of greenhouse gas (GHG) emissions are enteric fermentation from ruminants and manure management. An integrated strategy-combination approach incorporating nutrition and manure management is necessary to dramatically reduce GHGs and the carbon footprint of milk production. The aim of this review was to assess the effect of climate action mitigation strategies on the GHG production of ruminant animals. This review was based on the different references, which are textbooks, journals, proceedings, conferences, and abstracts accessed through Agricola, Agris, CAB Abstracts, Embase, MEDLINE, and the Web of Science. The research findings were done by using dairy cattle, sheep, and goat; the numbers of animals used in each experiment were given the majority of attention, and decisions were also made based on the method used to quantify methane (CH 4 ) and nitrous oxide. Enteric CH 4 per unit of milk was reduced by 6–8% when higher-starch corn silage was used in place of barley or alfalfa silage. Cows fed seaweed (1.77–2%, on dry matter [DM] basis) experienced a linear drop in enteric CH 4 emission from 383 to 400 g/d. Supplementation of vegetable fats (6%) and coconut oil (12 g/day) to ruminant diets can decrease CH 4 emissions by 21–40% and 50–61.2%, respectively. Similarly, the addition of 21.5 g nitrate/kg DM reduces CH 4 yield (17%) in sheep. Bovaer can reduce methane emissions (30%) for dairy cows. Feed processing and additives are alternative strategies to minimize GHG production in ruminants, but further studies on additives and their residual effect on livestock output is needed.

Episodic populist backlashes against urban climate actions

Populism is multilayered and involves two main dimensions – ideology and strategy – which are employed within and beyond political parties. These dimensions can result in sometimes overlapping but generally divergent backlashes, targeting specific climate and sustainability interventions in cities. This critical commentary presents episodic populist backlashes against urban climate actions by exploring how they create their own political landscapes across the political spectrum in cities against progressive urban climate agendas. Specifically, the article examines how episodic populist backlashes manifest on an urban scale and highlights the need for urban scholars to pay more attention to the phenomenon. The article proposes two complementary explanations for why populism precedes urban climate actions in episodic and thematic ways. These explanations include policy backlashes against diffused global climate norms in cities, and counter-movements and rhetoric against climate justice and what it entails, such as inclusion in decision-making and intersectionality. The article then concludes by offering a research agenda on the episodic populist backlashes against urban climate actions, which highlights the need for a better understanding of how episodic populist movements might emerge into global climate policy diffusion, and climate justice coupled with intersectionality in cities of the Global North and Global South.

Pope Francis the Roman Catholic Church and citizen attitudes towards climate change in Latin America

Studies on the relationship between religious attitudes and attitudes towards climate change and other environmental issues have tended to focus on the United States. While there is good reason to expect such a relationship to exist, our understanding of it is limited first and foremost by the limited number of country-comparative studies. This study aims to reduce this gap by investigating how trust in the Church and evaluations of Pope Francis affect the views of Latin Americans on anthropogenic climate change. Our study is based on data from the 2017 Latinobarómetro with 13,472 respondents based in 18 Latin American countries. Our findings reveal that Roman Catholics are less likely to believe in manmade climate change as compared to evangelical Christians and respondents belonging to no or any other denomination. We obtain the same negative relationship between trust in the (Catholic) Church and belief in anthropogenic climate change. However, favourable assessments of Pope Francis have a positive effect, and this assessment also has a positive moderating effect on the impact of trust in the Church on the outcome variable. These findings have important implications for climate policies, as they suggest that the public demand for climate action might increase if the Roman Catholic Church in their regional dioceses, rather than mostly the Pope, were to take and communicate a more coherent, affirmative position on climate change.

Using remote sensing technique to assess biomass energy potentials and appropriate site locations in Nigeria

In a bid to promote clean energy usage and conserve the forests, the Nigerian bio-energy policy was recently constituted, to help tackle the energy insecurity in the country and help increase its carbon credit in line with the United Nations development goals. This paper presents a Geographical Information System (GIS)-based assessment of biomass energy potentials and appropriate siting of biomass plant in Nigeria using remote sensing technique. It promotes sustainable and clean energy penetration and conserve forest life, which supports the UN SDGs on; Clean and Affordable Energy (SDG 7), Climate Action (SDG 13) and Life on Land, including forest sustainability (SDG 15), and the Federal Government of Nigeria's net-zero emission commitment. The weighted overlay decision analysis was employed considering multicriteria approach. The various vegetation, forest, water bodies, lands, water source locations, accessibility to roads, aspect and topography were the criteria that were considered for locating the biomass facility. Efforts were made to quantify the biomass energy potentials of the six geopolitical zones in Nigeria, with the possibility of locating biomass plant; North East, North West, North Central, South East, South West and South South. The results obtained in this study reflect that the north eastern part of Nigeria has the highest theoretical, technical and economical energy potentials of crop residues (1163.32, 399.73 and 110.56 PJ/yr, respectively), while the south eastern part has the least energy potential (52.36, 17.99 and 4.98 PJ/yr, respectively). Also, the north western part of Nigeria has the highest theoretical, technical and economical energy potentials of forest residues (260.18, 156.11 and 43.18 PJ/yr, respectively), while the south eastern part has the least energy potential (1.79, 1.08 and 0.30 PJ/yr, respectively). The remote sensing technique employed in this study suggested that the northern part of Nigeria is most suitable for siting biomass plants in the country.

Fiery trails: tourism's forest fire dance

ABSTRACT Tourism drives global economic growth and cultural exchange, but also raises climate vulnerability and forest fire concerns. This study explores the relationship between tourism and forest fires in emerging and advanced economies, aligned with UN's SDGs. Using ARDL model, findings show that a 1% increase in tourism development leads to 1% & 0.575% surge in forest fires in advanced and emerging economies respectively. In the short run, tourism leads to a decrease in forest fires in emerging economies, while in long-run risks increases for both panels of economies. This emphasises the need for eco-friendly practices for sustainable tourism. Governments should prioritise eco-tourism, green infrastructure, and SDG-13, SDG-9, SDG-11 for climate action, tech and sustainable transport.

International Trade Law: A Driver of Climate Action or a Roadblock?

Abstract Much has been written about changing the world's perception of international trade—from an area of development that will accelerate climate change to a powerful tool that can drive climate action. This article elaborates on four mechanisms of international trade law developed and honed by the World Trade Organization (WTO) that can play a pivotal role in accelerating climate action. The four mechanisms are the WTO's dispute resolution system, the Agreement on Technical Barriers to Trade (TBT), the Agreement on Trade-Related Aspects of Intellectual Property Rights (TRIPS), and the regional trade agreements (RTAs) negotiated under the WTO framework. Elucidating the WTO's role, this article supports the proposition that every multilateral institution can rise to the occasion and spearhead climate action in its own unique capacity.

Understanding the science-policy interface in urban climate governance from a co-production perspective: Insights from the cases of Hamburg and São Paulo

Urban governance, the interplay of governmental bodies with other actors shaping decision-making and its implementation, plays a key role for mitigation and adaptation measures in cities. While knowledge co-production is advanced as an instrumental approach to support climate action, a gap between knowledge and implementation persists. The objective of the article is to better understand the complex nature of urban climate governance with which science – through data and people – is expected to interplay with. We introduce a framework, based on the analytical lens of co-production, to unpack the entanglements of rules and norms, interests and visions, knowledge and capacities in a particular local context in order to identify aspects that may encourage meaningful knowledge co-production. We build upon two cities as case studies: Hamburg, Germany and São Paulo, Brazil. We present the results of interviews in dialogue with insights from city documents and an online workshop. We found that even though data and expertise is available, its use remains unsystematic, while climate action is mostly hampered by missing political capacity, silo mentalities, and a structural lack of resources. We identified a paradox where social transformation is addressed by technocratic solutions and a high appreciation for mutual learning in knowledge co-production processes. We conclude that to make use of its transformative potential, the implementation of knowledge co-production for climate action in practice needs to become more holistic. This includes the integration of non-climate information linked to local concerns and values as well as a shift in focus from output to its procedural benefits.
