However, translating degrowth insights into concrete strategies of collective action remains a challenge. To address this challenge, this paper develops a degrowth perspective for strategic spatial planning as well as a strategic approach for degrowth. I argue that a degrowth transition needs to address three strategic issues: depth, agency, and trajectory. Degrowth strategies aim for satiation, the satisfaction of all essential needs in a particular society. To do so, they rely on diffused societal power, raising from existing practices of reduction. Strategies also follow a nonlinear trajectory that seeks to prefigure satiation, popularize it among the masses, and then pressure existing institutions. Strategic spatial planning offers important insights for dealing with these challenges but needs to embrace satiation as a strategic goal. It can do so by creating complementarities between prefigurative practices that perform satiation. The article defines and illustrates these processes by looking at the making of Amsterdam's 'doughnut' strategy.</p>","PeriodicalId":47713,"journal":{"name":"Planning Theory","volume":"24 2","pages":"141-162"},"PeriodicalIF":3.4,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11925690/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143694075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In these densely populated areas, reliance on shared sanitation facilities is prevalent, driven by spatial constraints, insecure land tenure, limited infrastructure, and socio-economic marginalization. While these facilities are often criticized for poor quality and safety concerns, they are essential in contexts where individual household toilets are infeasible. This critical review synthesizes evidence from 93 peer-reviewed studies and 9 grey literature sources across 22 countries, with a focus on Sub-Saharan Africa and South Asia. The analysis reveals that shared sanitation, while often classified as substandard, is an unavoidable interim solution in contexts where individual household facilities are impractical. Effective interventions, such as robust facility designs, participatory management models, and targeted behavior-change strategies, demonstrate significant potential to improve cleanliness, accessibility, and safety. However, systemic barriers—such as inadequate policies and regulations, fragmented land management systems, constrained socio-economic capacities, insufficient water and sanitation infrastructure, and weak governance typical of informal settlements—must be overcome to enhance the usability of shared sanitation facilities. The review underscores the necessity of integrating shared sanitation improvements within broader urban planning frameworks to achieve Sustainable Development Goals 6.2 and 11. By situating sanitation interventions within the socio-political realities of informal settlements, this study advances actionable insights for fostering resilient and inclusive urban sanitation systems in rapidly growing cities.</div></div>","PeriodicalId":48463,"journal":{"name":"World Development","volume":"192 ","pages":"Article 107012"},"PeriodicalIF":5.4,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, this concept is disputed due to paradigmatic differences and the proliferation of concepts presented. This article aims to clarify the conceptual ambiguities surrounding SJ and extract its defining categories regardless of existing intellectual paradigms. More precisely, this paper wants to understand the common concepts of SJ definitions to provide an integrated definition for it. For this purpose, the present study was methodically extracted using a systematic review and coded with a qualitative content analysis. The results reveal seven underlying categories of SJ under the headings of “participation”, “power and governance”, “diversity and plurality”, “equality”, “access”, “equity” and “fairness”. Combining these categories and their sub-categories forms an integrated definition that can be considered the main basis for the efficiency of theories, policies, and future planning. Also, a deeper understanding of SJ formative categories can be achieved by linking this new definition with intellectual paradigms and spatial planning theories.</div></div>","PeriodicalId":48376,"journal":{"name":"Habitat International","volume":"160 ","pages":""},"PeriodicalIF":6.5,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143807033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our results support models in which the cross-section of price–earnings ratios is driven mainly by discount rates or mispricing rather than future earnings growth. Evaluating six models of the value premium, we find that most models struggle to match our results; however, models with long-lived differences in risk exposure or gradual learning about parameters perform the best. The lack of earnings growth differences at long horizons provides new evidence in favor of long-run return predictability.

With improved material standards, a large number of middle-class individuals with higher consumption demand and purchasing power are challenging ecological sustainability through frequent and high-intensity economic activities. This study investigates the ecological entanglements of the middle class and constructs a novel theoretical framework that maps the pathways through which the middle class influences the ecological footprint (<em>EF</em>) from power and consumption perspectives. To quantitatively verify whether the coevolution of the middle class and the <em>EF</em> can transcend the zero-sum tradeoffs and achieve socioecological equilibrium, we innovatively use macrostatistics to estimate the size of the middle class (<em>SMC</em>), constructing a comparable cross-country dataset for this variable. We then analyze the correlation between <em>EF</em> and the <em>SMC</em> using an interactive fixed effects model with panel data for 60 countries from 2000 to 2020 to examine whether a tradeoff is evident between the two variables. The results reveal strong tradeoffs between the expanding <em>SMC</em>, which tends to increase countries' <em>EF</em>. Mitigating or reversing ecological degradation may compromise the rationality of income distribution, potentially neglecting environmental issues that accompany policies intended to narrow the wealth gap. Further subgroup analysis reveals that residents in higher-income countries typically engage in higher levels of consumption and governance, but subsequent sustainability has been historically weak, resulting in a stronger positive and weaker negative impact of the <em>SMC</em> on the <em>EF</em>. Our empirical insights demonstrate the inherent contradiction within the United Nations Sustainable Development Goal targets with significant implications for advancing sustainable shared prosperity by leveraging middle-class consumptions.</div></div>","PeriodicalId":51021,"journal":{"name":"Ecological Economics","volume":"235 ","pages":""},"PeriodicalIF":6.6,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143808056","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"经济学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, a k-means cluster analysis is applied to identify impact patterns among geographical units. Our results indicate that environmental features have different impact contributions on the paces of different travel modes, all demonstrating nonlinear relationships with thresholds.
