Pursuit of its ambitious vision has led to ambiguity in terms of ecological economics' paradigms, methodology, and subject matter. There remains a need for comprehensive methodologies and for nuanced discussions of methodological pluralism and action-oriented research practice. We present a pragmatist ecological economics as one foundation to practicing ecological economics. We synthesize the basic normative assumptions of a pragmatist philosophy with the foundational goals of ecological economics. This synthesis provides potential researchers with foundations including a basic scientific worldview, a topical focus on a quasi-distinct portion of human-nature relationships, two broad burning questions, a basic menu of methods, and action-oriented goals for applying ecological economics in practice. Methodological pluralism is embraced, and conflicting normative assumptions are reconciled with the recognition that singular inquiries provide incomplete or partial knowledge, not competing knowledge. By integrating into applied contexts, in large part by building relationships with practitioners and the diverse publics, we suggest that there is opportunity to co-develop processes and forums that at least can help us understand one another better on our collective effort toward sustainability.</div></div>","PeriodicalId":51021,"journal":{"name":"Ecological Economics","volume":null,"pages":null},"PeriodicalIF":6.6,"publicationDate":"2024-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142529042","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}

The role of infrastructure and services provisioning, especially where these are fossil-fueled, emerges as key in understanding these patterns. Geographic groupings of EU member states—Northern, Eastern, Mediterranean, and Central—further explain the inequalities that deepened following the recession.

Trade pattern is characterized by the direction, composition, and magnitude of trade, indicating an economy imports what types (composition) and magnitudes of goods or services from where (direction). We find that CGTP aggravated socioeconomic and environmental inequality between countries in two ways: 1) the amount of indicators that significantly worsened due to CGTP decreased from 8 indicators (2004–2007) to 1 (2011–2014) for high-income and upper-middle-income countries, but increased from 5 to 14 for lower-middle-income and low-income countries; 2) CGTP led to a coupling of value added with most natural resource consumption and environmental pollution indicators for low-income countries, while they strengthened decoupling or reducing coupling for other countries.

We use remotely sensed data to estimate difference-in-differences models accounting for differences in baseline characteristics and multiple time periods. Our case study, Sulawesi Island, is primarily shaped by smallholder farmer land use, where KPHs can exert significant influence. We do not find evidence of an overall effect of KPHs on deforestation. However, we observe intriguing heterogeneous effects depending on the year, including significantly less deforestation in already-established KPHs during the El Niño years of 2015–16, and a notable impact on the reduction of forest loss due to fire in some early-established KPHs.

However, empirical evidence of the role it can play is lacking, and its integration into standard insurance strategies – for example, the use of pesticides or market-based insurance – has been understudied. To begin to fill this gap, this study developed an original conceptual framework to estimate the insurance value provided by semi-natural habitats in a crop production context. The framework was then applied to a case study in western France, focusing on the value of natural pest control provided by grassland areas in the context of oilseed rape production. We evaluated the insurance role of grasslands for pest control and estimated this at a value of €50 per hectare. However, this estimation varied greatly according to the farmer's risk-mitigation strategies considered. We found that omitting agricultural inputs (e.g. risk-mitigating inputs such as pesticides) overestimated the insurance value of grassland areas due to the substitution effect between different types of insurance tools. Despite this variation, the findings show that it is nonetheless always optimal for farmers to maintain grassland areas to manage risk. This study provides empirical evidence of the insurance role of semi-natural habitats in an agricultural production context and offers new arguments for the ecological intensification of agriculture.</div></div>","PeriodicalId":51021,"journal":{"name":"Ecological Economics","volume":null,"pages":null},"PeriodicalIF":6.6,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142418321","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}

Our findings also highlight some heterogeneity, confirming the prominent role of industrialized and newly emerging countries such as China and India in global carbon emissions.
