High treatment costs represent a major choke point to achieving forest management goals, but selling timber and biomass from forest thinning can offset costs and provide the revenue to help rapidly scale management actions. In this study, we assess how forest product market conditions influence the economic feasibility and scale of forest management by modeling treatment potential across a Northern Sierra Nevada landscape using the US Forest Service's BioSum tool. We evaluate treatment outcomes across nine economic scenarios, incorporating wood and biomass price variations and treatment subsidies. Results indicate that baseline pricing assumptions facilitate aggressive forest treatment where thinning is feasible and needed, but a 50 % drop in forest product prices led to a one-third decline in treated area. These reductions are completely offset by a $500/acre treatment subsidy, suggesting that subsidies could serve as a ‘price floor’ to maintain treatment levels through market fluctuations. Optimal, cost-effective treatments overwhelmingly utilized prescribed fire following thinning, emphasizing the role of fire-inclusive approaches for forest treatment. While study findings indicate that forest product markets can support landscape-scale treatments, the capacity of regional processing facilities currently limits full utilization of forest products, underscoring the importance of expanding wood and biomass utilization infrastructure to realize the potential of market-driven strategies for improving forest resilience in the Sierra Nevada and similar fire-prone regions.</div></div>","PeriodicalId":34472,"journal":{"name":"Current Research in Environmental Sustainability","volume":"9 ","pages":"Article 100296"},"PeriodicalIF":3.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144203067","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This examination will serve as a crucial resource for shaping policies, directing research efforts, and fostering public discourse. This systematic review thoroughly analyzes the impact of climate change on food and nutritional security in India. Examining 231 articles, the study delves into various dimensions, including availability, accessibility, utilization, and stability. The review utilized Web of Science, PubMed, and CABI review, employing 100 different keywords. Temperature variations, erratic rainfall, and extreme weather events disrupt crops, livestock, poultry, and aquaculture production (food availability), leading to food shortages, income loss, and elevated food prices (accessibility), especially affecting low-income groups. Indirectly, climate change affects livelihoods and incomes, exacerbating inequalities and leading to the displacement of marginalized communities (stability), thereby escalating food insecurity and malnutrition (utilization). However, few studies cover diverse aspects such as the influence of climate change on traditional crops, nutritional value, agricultural biodiversity, food distribution systems, indigenous food systems, and nutrition outcomes, particularly for vulnerable groups like women and children. Hence, there is a pressing need for a more holistic and integrated approach to tackle the impacts of climate change on food and nutrition security in India.</div></div>","PeriodicalId":34472,"journal":{"name":"Current Research in Environmental Sustainability","volume":"9 ","pages":"Article 100286"},"PeriodicalIF":3.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143682686","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}

This study aimed to assess the economic viability, energy efficiency, and environmental impact of seven different coconut-based cropping systems in Goa, India. The systems included coconut (<em>Cocos nucifera</em> L) monocrop and various intercropping combinations such as drumstick (<em>Moringa oleifera</em>) and papaya (<em>Carica papaya</em>), heliconia (<em>Heliconia psittacorum</em>) or banana (<em>Musa</em> sp.,) and lemon (<em>Citrus limon</em>), pineapple (<em>Ananas comosus</em>) and passion fruit (<em>Passiflora edulis</em>), and crossandra (<em>Crossandra infundibuliformis</em>). Results indicated that the coconut + pineapple + passion fruit system and coconut + heliconia system showed promising in terms of both economic returns and energy output. The coconut + papaya + drumstick system, however, showed the highest global warming potential (GWP) due to considerable input requirements during the crop cycle. The coconut + pineapple + passion fruit system exhibited the highest economic returns with an average additional coconut equivalent yield of 8605 nuts per hectare, a high benefit-to-cost ratio of 1.99, with an average net return of USD 1558.5 per hectare. Energy efficiency among the systems was compared based on computed energy values for inputs and outputs, highest efficiency at 45.3 was recorded in the coconut + heliconia system. Using the ReCiPe 2016 (H) Midpoint method, life cycle inventories were calculated, and the coconut monocrop system showed the lowest GWP due to its lower input consumption. The agroforestry combinations of coconut + crossandra and coconut + soursop showed nearly equivalent GWP as that of coconut monocrop despite their higher input requirement over coconut monocrop. On-farm emissions were found to contribute significantly to the GWP, ranging from 73 % in coconut + crossandra to 40 % in coconut + heliconia. Nitrogenous fertilizers and fuel-intensive tillage operations were identified as major contributors to both higher energy consumption and GWP in all the cropping systems. In conclusion, the coconut+soursop system has proven to be optimally productive, profitable, energy-efficient, and eco-friendly. In addition, this system offers the opportunity to incorporate various intercrops such as pepper and pineapple, to improve multiple ecosystem services in the West Coast region of India. The findings emphasize that selecting low-input, shade-adapted crops can optimize resource use, reduce emissions, and enhance sustainability.</div></div>","PeriodicalId":34472,"journal":{"name":"Current Research in Environmental Sustainability","volume":"9 ","pages":"Article 100289"},"PeriodicalIF":3.7,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143682687","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}

Therefore, evaluating and revising policies and management approaches from the perspective of achieving WEFE nexus goals can operationalize sustainable agricultural development. Despite the highlighted importance of this connection, there is no comprehensive framework and method for its implementation considering various environmental criteria along with the evaluation of water resource management policies. This study aims to first extract the optimal sustainable solution by considering all Water-Energy-Food (WEF) nexus goals combined with environmental objectives such as minimizing the use of fertilizers, pesticides, and CO2 emissions, and maximizing wetland conservation scores using the NSGA-II method. Then, it estimates the effects of water resource management policies, including policies for reducing available water resources (P1), improving irrigation efficiency (P2), and crop pattern modification (P3), using the PMP model and evaluates them by calculating the Distance-to-Optimal Solution Index (DOSI). For this purpose, the Jiroft plain in Kerman province, Iran, was selected as the study area. The results showed that the optimal sustainable cropping pattern, with a reduction of 3988 ha from the current cultivated area, significantly improves environmental criteria such as reducing the use of fertilizers and pesticides, CO2 emissions, and increasing the conservation of the Jazmourian wetland. Additionally, it was found that the DOSI for the current pattern is −2.70, and for the patterns with the implementation of policies P1, P2, and P3, it is −2.89, −3.22, and − 1.19, respectively. Therefore, the policy of modifying the cropping pattern towards crops with lower water requirements (P3) can improve the sustainability of the region's agriculture. In contrast, policies for reducing available water resources (P1) and improving irrigation efficiency (P2) not only do not improve the sustainability compared to the current conditions but also worsen it. Overall, the framework used to identify the best water resource management policies by leveraging the comprehensive WEFE nexus approach will be a strategy to ensure sustainable agricultural development.</div></div>","PeriodicalId":34472,"journal":{"name":"Current Research in Environmental Sustainability","volume":"10 ","pages":"Article 100310"},"PeriodicalIF":3.8,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145320143","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inspired by Nego Bispo's concept of \"confluence,\" which emphasizes the coexistence of diverse knowledge systems without losing their unique identities, this article proposes an approach that is reflective of prevailing inequalities in transdisciplinarity without giving up on the goal of co-creation. Based on a case study in Siribinha, an artisanal fishing village on the northern coast of Bahia, Brazil, we examine how power dynamics shape the interactions between community members, local policy makers, and researchers. Over the past nine years, our research team has employed participant observation, semi-structured interviews, design research methods, and arts-based methods in collaborative work in and with this community. The findings reveal that power imbalances, rooted in historical marginalization, influence who participates in decision-making processes and whose voices are heard. The community's sense of disenfranchisement is linked to the dominance of external actors in local decision making.
