However, these programs have faced criticism, particularly regarding their impact on participants' livelihoods and resource conservation. This study evaluates the performance of the Forest Coffee Certification Program (FCCP), implemented in the Belete-Gera forest area over the past ten years (2011–2022), focusing on its contributions to household income and its effects on resource conservation. Additionally, it investigates whether premium payments resulting from the certification have incentivized households to comply with FCCP objectives and requirements. Multiple data collection methods were employed, including household surveys, key informant interviews, stakeholder workshops, and desk reviews. Results indicate a substantial increase in the total sales volume of forest coffee and revenues, whereas the volumes of forest coffee supplied to the cooperatives showed decreasing trends over the past ten years. Consequently, the premium payment received from certified forest coffee export also showed a substantial decreasing trend. The current premium payment of $0.87 (46 birr) per kg is identified as the optimal incentive for compliance with FCCP requirements. The results also indicate that the certification program contributed to forest conservation by creating incentives that fostered a sense of ownership within the local community, particularly during the early stages of its implementation. The study concludes that improving price differentials and ensuring fairer premium distribution could strengthen the FCCP's impact on livelihoods and forest conservation. Moreover, the program needs to address the decreasing trend in forest coffee cooperative supplies to sustain its long-term benefits.</div></div>","PeriodicalId":36171,"journal":{"name":"Environmental and Sustainability Indicators","volume":"25 ","pages":"Article 100569"},"PeriodicalIF":5.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143179959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our methods determine the source (diffuse agricultural and wastewater point source) and location (coastal and freshwater) of the University’s phosphorus footprint impacts, estimate the relative contribution of nitrogen and phosphorus across existing eutrophication damage costs, and then apply the results to the University’s phosphorus footprint. We found that activities at the University result in approximately $76 000 of annual downstream costs to society due to its phosphorus footprint ($2.08/kg of phosphorus released to the environment). About 48% of those damages are incurred in the Chesapeake Bay, which flows into the Atlantic Ocean and is the largest estuary in the United States, while 7% are incurred in the Gulf of Mexico. The remainder (45%) of costs are incurred in freshwater systems across both watersheds. Our findings are likely an underestimate of true societal impacts, as impacts such as losses of ecosystem services are difficult to value. However, we emphasize that this method is transferable and can be used by other institutions to calculate their phosphorus damage costs, providing a more holistic accounting of downstream environmental impacts.</div></div>","PeriodicalId":36171,"journal":{"name":"Environmental and Sustainability Indicators","volume":"25 ","pages":"Article 100560"},"PeriodicalIF":5.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143180319","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, interprovincial trade has exerted greater environmental pressure on developing provinces (e.g., Nei Mongol, Jilin and Heilongjiang) with better natural resource endowments than developed provinces (e.g., Beijing, Tianjin, Shanghai).

This study developed a benchmarking rationale accommodating local opportunities and constraints for effectively incentivising locally-tuned sustainability improvements. This was carried out by analysing energy and water use on the 1103 vineyards enrolled in the Sustainable Wine-growing New Zealand scheme. Regression models to predict spatial and temporal variations of energy and water use explained relatively large proportions of the resource use variance. Production area and region were common and significant predictors of resource efficiency. A 59% increase over time in fuel efficiency took place in vineyards instigating energy reduction plans and actions. The vineyards' rank performance differed widely when benchmarked within the entire sector or within other vineyards of equivalent characteristics, specifically for agroecological and production related characteristics influencing performance. For example, one vineyard ranked at the 20 percentile in fuel efficiency within the sector, yet at the 75 percentile when compared against vineyards in its own region and with a similar production area. Aggregated and non-locally tuned benchmarking might best suit consumers and national-level policy makers, but they do not capture the local and diverse challenges faced by the individual farmers. Use of locally-tuned benchmarking approaches can better identify actual sustainability improvement opportunities and may enhance farmers’ trust in the sustainability exercise, improve participation and better incentivise change towards sustainability.</div></div>","PeriodicalId":36171,"journal":{"name":"Environmental and Sustainability Indicators","volume":"25 ","pages":"Article 100536"},"PeriodicalIF":5.4,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143180882","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These variables cover climatic variables (rainfall), sediment variables (salinity, pH, organic carbon, nitrogen, phosphorus), water variables (Salinity, pH, temperature, nitrate, phosphate), primary productivity (Chlorophyll-a) and prey availability (mean fish stock availability). Densities of all the studied wader species decreased significantly from 2010 to 2019, with highest densities in agroecosystems or estuarine habitats and in post-monsoon seasons but lowest in mudflats and in monsoon seasons. Structural equational modelling revealed that rainfall and organic carbon positively affected the primary productivity, whereas water variables (nitrate, salinity and phosphate) positively affected the fish stock availability. This in turn positively affected the density of large wading birds. The decreasing trend of water nitrate negatively affected the primary productivity and density of waterbirds while rainfall negatively affected fish stock availability and waterbird density. Sediment phosphorous adversely affected both the biotic variables and the density of waterbirds. Sediment variables (salinity, pH, and phosphorus) increased over years, whereas organic carbon and nitrogen in the sediment decreased significantly. Salinity, water temperature, pH, and phosphate showed a significant increase while water nitrate, and chlorophyll-a decreased over the period of study. Significant decline in fish stock availability and altered environmental variables resulted in long term decline in the abundance of wading birds. Thus, large waders have adapted to these long-term, anthropogenically driven, environmental changes by shifting to agroecosystems and estuaries as their alternate foraging habitats.
