Although there is a substantial amount of information available, there is still a continuing discussion regarding the capacity of LCAT to enhance agricultural productivity, improve farmers' quality of life, and mitigate environmental damage. In order to draw reliable conclusions about the impacts of LCAT and understand the reasons for heterogeneous effects across different studies, we employ a meta-regression to conduct a thorough analysis of 60 empirical studies conducted in the Asian region. The findings suggest that the implementation of LCAT has no significant effect on the overall welfare of farmers in terms of their collective social, economic, and ecological dimensions. However, whether examining the economic or social consequences individually, LCAT demonstrates positive results. The magnitude of these outcomes varies depending on several characteristics. Specifically, studies based on plot-level data, conducted in the rest of Asia, excluding South and East Asia, with the “economic effects” category such as income and profits as the dependent variables, involving younger and less-educated farmers, larger cultivation areas, and LCAT with comprehensive attributes, tend to show more significantly positive effects. Furthermore, a significant “U” relationship can be observed between per capita GDP and the positive effects of LCAT adoption. Therefore, it is crucial to thoroughly evaluate the welfare effects of LCAT adoption by considering comprehensive factors such as farmers' characteristics and regional environmental conditions. Policymakers should carefully tailor suitable LCAT for specific circumstances, ultimately striving to achieve agricultural carbon reduction, enhancement of carbon sequestration, and an overall improvement in farmers' welfare.</p></div>","PeriodicalId":51021,"journal":{"name":"Ecological Economics","volume":null,"pages":null},"PeriodicalIF":6.6,"publicationDate":"2024-07-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141862569","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}

AAD implemented large-scale restoration and livelihood development activities aimed at increasing household income generation from restoration efforts and fostering alternative agricultural activities in an improved ecosystem. Using a multi-method strategy, we assess the impacts of landscape restoration at the household level. We leverage pre-restoration remote-sensed data and machine learning algorithms to identify comparable land sites to the program's restoration areas. Comparison households are selected from communities bordering these sites, replicating the AAD's targeting process. Our impact evaluation strategy employs the doubly-robust inverse-probability weighting regression adjustment model. Key findings indicate that land restoration activities did not negatively impact participant households' food security levels, despite some communal land use restrictions. Moreover, there was a reduction in moderate food insecurity observed. Household livelihood strategies in restoration areas shifted towards more climate-resilient activities, with decreased reliance on crop sales and increased participation in sales of livestock by-products and high-value Non-Timber Forest Products (NTFP). Compared to participants that were involved in the program at a later stage, early participants experienced larger impacts, further validating these findings. Our results highlight the role of participatory approaches to restoration, and the need for multi-scale approaches that include the identification of communities’ immediate needs but also, increase market access, to enhance the synergies of restoration’s biophysical and socioeconomic outcomes. Our analysis also offers an innovative approach for future ex-post evaluations of land restoration programs. The lack of evidence from rigorous methods is a recurrent issue in environmental interventions.</p></div>","PeriodicalId":51021,"journal":{"name":"Ecological Economics","volume":null,"pages":null},"PeriodicalIF":6.6,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141768924","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}

Indeed, budgetary pressures are as defaults and economic recessions, combined with difficulties in accessing financial markets, which are often triggered by a series of sovereign debt restructurings and defaults, and have led some resource-rich African countries to turn to resource-backed loans to finance infrastructure projects to achieve long-term sustainable development goals. In this paper, we use the entropy balancing method to test whether resource-backed loans have a causal impact on the ecological efficiency of human development of African economies. Across a battery of robustness checks, the estimation results indicate that resource-backed loans have a positive and statistically significant impact on ecological efficiency of human development. Nonetheless, when resource-backed loans are disaggregated to run the regressions, we find that oil-backed loans and minerals resource-backed loans increase ecological efficiency of human development while cocoa and tobacco resource-backed loans are negatively associated to ecological efficiency of human development. The main findings of the study suggest that resource-backed loans agreements in general, and cocoa and tobacco in particular, should include strict clean development provisions and the implementation of actions to mitigate the negative environmental impact of these loans for borrowing countries.</p></div>","PeriodicalId":51021,"journal":{"name":"Ecological Economics","volume":null,"pages":null},"PeriodicalIF":6.6,"publicationDate":"2024-07-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0921800924001927/pdfft?md5=26dc0f187a13f4ce4e631ff67ba6d1da&pid=1-s2.0-S0921800924001927-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141768927","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}

For this reason, we begin our response with an introduction to the German transport context, including developments in car ownership and background on the German Climate Protection Act that legally requires all economic sectors to reduce emissions. This framing is important to correctly understand our response to Sieg (2024) as well as Eisenkopf et al. (2024). Overall, we note that many of their criticisms lack merit, while others depend on viewpoint. We conclude that, specifically considering current price levels for fuels, our findings are not in question: a speed limit is warranted for welfare reasons; it is supported by a majority of the population; and it can help closing the emission gap in the transport sector. Findings are also discussed within the wider framework of “desirable” transport systems, illustrating the limitations of CBA and the dangers of tailoring results in ways that lend credibility to specific forms of transport governance, as apparently favored by Sieg (2024) and Eisenkopf et al.

However, two practical problems must be solved to formulate effective absolute cap policies. First, there is always a conflict between efficiency and fairness. Second, the allocation scheme is often infeasible without considering the materials balance (MB) principle, especially in multi-pollutant scenarios. The MB principle comes from the physics field and requires that the mass of inputs is equal to the mass of both desired and undesired outputs. To address these two problems, this paper proposes joint allocation and compensation schemes in multi-pollutant scenarios based on the MB principle. The new approach can simultaneously satisfy efficiency and fairness principles and improve the feasibility and accuracy of allocation and compensation schemes. A case of China's thermal power industry is used to demonstrate the approach. These results indicate that the principles of efficiency and fairness can be satisfied simultaneously by the combination of the allocation scheme and compensation scheme. If the MB principle is not considered, the abatement potential and potential benefit may be overestimated, and the allocation scheme is infeasible for most provinces. Moreover, the compensation amounts may be significantly underestimated without the MB principle.</p></div>","PeriodicalId":51021,"journal":{"name":"Ecological Economics","volume":null,"pages":null},"PeriodicalIF":6.6,"publicationDate":"2024-07-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141728770","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}
