The frequent application of various fertilizers, has resulted in soil pollution, which is further exacerbated by water scarcity. The indiscriminate use of chemical fertilizers has led to devastating consequences such as reduction of soil fertility, environmental contamination, increased insect resistance, destroyed biodiversity, and ultimately resulted in heavy economic losses. Another approach being investigated and explored is the use of biofertilizers, which is a better supplement to improve crop yields without harming the environment. However, a significant challenge lies in the fact that plants cannot utilize whole biofertilizer intact, as much of the portion remained unabsorbed or became part of the soil instead of reaching the targeted site. This problem can be solved by nanotechnology; nano-biofertilizers increase tolerance against abiotic stresses. They improve plant morphology, biochemistry and yield, as well as soil composition. Thus, in comparison to conventional chemical fertilizers, nano-biofertilizer produce eco-friendly, sustainable and longer-lasting outcomes. This paper discusses a review of biofertilizer formulations based on nanotechnology for sustainable agriculture development. The invention and application of nano-biofertilizer on various plant species is highlighted in this paper, along with how it improves the growth and development of plants.</p></div>","PeriodicalId":36171,"journal":{"name":"Environmental and Sustainability Indicators","volume":"24 ","pages":"Article 100470"},"PeriodicalIF":5.4,"publicationDate":"2024-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2665972724001387/pdfft?md5=265f7f866946d8404725a4900934c24d&pid=1-s2.0-S2665972724001387-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142151657","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}

However, there is a lack of empirical evidence on the key elements that drive sustainability within these cooperatives. This survey study aims to develop a sustainability performance checklist tailored for fisheries cooperatives throughout their lifecycle. Initially, a preliminary list of five-point Likert scale sustainability factors was created and reviewed through interviews with experts from both fisheries academic and executive sectors. Their feedback contributed to refining the checklist, ensuring its relevance, clarity, and simplicity. Experts from both the academic and executive sectors of fisheries cooperatives have confirmed the content validity of the economic, social, and environmental criteria included in the checklist. The data collected across 61 cooperatives. To identify the key factors influencing the sustainability performance of fisheries cooperatives throughout their lifecycle, a factor analysis was performed, employing the Varimax rotation method. The findings indicate that economic considerations are the primary focus during the initial establishment of fisheries cooperatives. As these cooperatives evolve through the growth and consolidation phases, social factors become increasingly significant. Additionally, the study highlights the essential role of environmental aspects in maintaining the stability and balance of these cooperatives. The research underscores the interdependence of economic, social, and environmental elements in fostering the sustainability of fisheries cooperatives. These insights are particularly relevant for policymakers, managers, and stakeholders in fisheries management. Furthermore, the developed sustainability performance checklist and weighting system can effectively assist in assessing and enhancing the sustainability of fisheries cooperatives.</p></div>","PeriodicalId":36171,"journal":{"name":"Environmental and Sustainability Indicators","volume":"24 ","pages":"Article 100469"},"PeriodicalIF":5.4,"publicationDate":"2024-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2665972724001375/pdfft?md5=73188cac380d1920111726a9c5a3d489&pid=1-s2.0-S2665972724001375-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142130181","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 degraded lands, crop cultivation is not sustainable without adopting resource conservation practices. Agroforestry systems that incorporate canopy management practices have the potential to significantly contribute to the restoration of degraded land by preserving natural resources. We hypothesized that restoring degraded land through a combination of tree planting, shade-loving crop cultivation, canopy management, and land management practice could result in significant improvements in soil fertility, productivity, and carbon sequestration. To test this hypothesis, an experiment was conducted involving a combination of Mulberry (<em>Morus alba</em> L.) and Turmeric (<em>Curcuma longa</em>) in conjunction with canopy management practices including coppicing pollarding and lopping. This experiment, designed as a randomized block design (RBD) with eight treatments, evaluated the impacts on soil erosion, soil health, and carbon sequestration over four years. The results revealed that mulberry under coppicing combined with turmeric treatment reduced the runoff by 45.3% and 28.7% compared to cultivated fallow and sole turmeric, respectively. Sole mulberry under coppicing treatment showed even greater efficacy, reducing soil loss by 73.3% and 57.8% over cultivated fallow and sole turmeric, respectively. Additionally, the mulberry under coppicing combined with turmeric treatment decreased the losses of N, P, and K by 31.8%, 63%, and 22.5%, respectively, compared to sole turmeric. Moreover, the mulberry under pollarding combined with turmeric enhanced SOC stock and SOC sequestration rates by 23.3% and 107.4%, respectively, over fallow and sole turmeric. This treatment also increased soil moisture and turmeric yield by 25% and 17.6%, respectively, over sole turmeric. Furthermore, sole mulberry under lopping treatment produced the highest above-ground biomass (AGB), carbon stock (CS), and carbon sequestration (CSe), followed by lopping combined with turmeric and pollarding combined with turmeric. Hence, the adoption of a mulberry-based agroforestry system with canopy management practices system could be a sustainable technique for restoring the degraded land. Therefore, this system could be recommended for improving soil fertility, reducing soil degradation, and improving productivity, particularly in the Western Himalayan region of India or similar agro-climatic regions worldwide.</p></div>","PeriodicalId":36171,"journal":{"name":"Environmental and Sustainability Indicators","volume":"24 ","pages":"Article 100467"},"PeriodicalIF":5.4,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2665972724001351/pdfft?md5=50652ee39276dd2a2f04c904d65c2c0a&pid=1-s2.0-S2665972724001351-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142095960","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}

For this, we individually optimized the objectives: maximizing the WEFN index (O₁), minimizing CO₂ emissions (O₂), reducing chemical fertilizer consumption (O₃), minimizing chemical pesticide usage (O₄), and maximizing gross margin (O₅) under various electrical conductivity (EC) scenarios (optimistic, moderate, and pessimistic) within the irrigation network of the Jiroft plain in Iran.

Specifically, in the pessimistic scenario with an EC irrigation water level of 2.25 ds/m, crops such as onions, tomatoes, and potatoes were replaced within the optimal cropping pattern by wheat, barley, and green-maize, leading to a notable decline in program efficiency. The results from the MOP optimization model indicated that in the pessimistic EC irrigation water scenario, the WEFN index, CO₂ emissions, fertilizer consumption, pesticide consumption, and gross margin would change by approximately +12%, −48%, −28%, −8%, and −74%, respectively, compared to the baseline scenario.

The present study provides avenues vital to improving guidance for sustainable species management. In this region, sardine is divided administratively into three stocks (northern: stock N, central: stock A + B, and southern: stock C). Thus, the present study used two Surplus Production Models (SPM) to evaluate sardine's stock status. Sardine's catch and scientific survey biomass data obtained from FAO-CECAF's (Fishery Committee for the Eastern Central Atlantic (CECAF)) latest reports were used in this analysis to fit the SPMs and investigate the effectiveness of the available catch-per-unit-effort (CPUE) trends in setting the total allowable catch (TAC) for sustaining the different sardine stocks in the region. Results from the SPMs indicate that the sardine stock in the north is fished at optimum levels. Meanwhile, the SPMs output based on the scientific survey biomass indices indicated a healthy state for the central and southern sardine stocks. Similarly, the fishery CPUE indices for the central and southern stocks showed similar biomass trends compared to the survey biomass index, indicating healthy stock status. Therefore, in cases where survey biomass index data is unavailable to run stock assessments, this study suggests that sardine fishery CPUEs could be used in SPMs to monitor biomass trends over time and may also provide stock status proxies. Additionally, with rapid climate and other environmental changes, sardine stocks must be regularly monitored with consistent and comparable scientific methodologies and updated fisheries time series data.</p></div>","PeriodicalId":36171,"journal":{"name":"Environmental and Sustainability Indicators","volume":"23 ","pages":"Article 100460"},"PeriodicalIF":5.4,"publicationDate":"2024-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2665972724001284/pdfft?md5=41567c3a6450df2b9f939f8fb663f30f&pid=1-s2.0-S2665972724001284-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142011251","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}
