Particularly, fruit tree-based agroforestry practice plays a significant role in improving productivity as well as soil fertility management. This study aimed to determine the contribution of on-farm avocado fruit tree-based agroforestry practice on selected soil physicochemical properties in the case of Inguti small watershed. Field survey and laboratory analyses were carried out based on selected physicochemical properties. Soil samples were taken from 12 sample avocado trees at 3 radial distances (under, near, and far from tree canopy) and two depths (0–20 cm and 20–40 cm) in four directions. Soil composite samples were taken for laboratory analysis. To investigate its contribution to selected soil’s physicochemical properties texture, bulk density, organic matter and carbon, pH, total nitrogen, available phosphorus, and available potassium were considered and the significant variation among treatments were analyzed. Based on the result of the study, except soil texture and soil pH, all other investigated soil physical (bulk density) and chemical properties (organic matter, organic carbon, total nitrogen, available phosphorus and potassium) were significantly varied for distance from avocado tree and soil depth from the surface with a p-value of bulk density P < 0.000 and 0.001), organic matter (P < 0.000 and 0.005), organic carbon (P < 0.000 and 0.006), pH (P < 0.00 and 0.626ns), total nitrogen (P < 0.000 and 0.006), available phosphorus (P < 0.002 and 0.01) and potassium (P < 0.002 and 0.01) for distance and depth respectively. So, on-farm avocado (Persea americana) has a significant contribution to soil physicochemical properties in the study watershed.","PeriodicalId":29858,"journal":{"name":"Sustainable Environment","volume":"97 3","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138596093","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}

However, to date, there has been relatively little focus on holistically developed frameworks to assess farmers’ SA potential or their linkage to farmers’ readiness for SA practices such as adopting more organics in farming, particularly in Sri Lanka. To address this gap, we developed a conceptual model to determine farmers’ resilience in implementing more organic use in farming. The model developed was a philosophical combination of ecosystem resilience theory, the rural livelihood assessment framework, and the dimensions of personal readiness to commit to or experience an action. We derived composite indicators to explain the variances of these constructs through a detailed literature review, followed by pre-testing indicators. Data were collected from 386 participants using a structured questionnaire consisting of 119 items. Partial least squares structural equation modelling techniques were used to analyze the variables and path coefficients of the model. Farmers’ sustainable agricultural potential (SAP) was found to be moderately strong in this rice cultivation region. This potential positively influences their readiness for adapting more organics in farming. Some farmers perceived government support as effective. However, this support has not yet been transformed into organic adaptation. Natural capital was identified as the most influential factor in organic farming. Farmers’ education, gender, the extent of sowing, farming methods, and agro-input type were moderating factors between SAP and their readiness for organic matter. Farmers did not deny organic adaptation and understood the need to reduce the use of chemicals.","PeriodicalId":29858,"journal":{"name":"Sustainable Environment","volume":"1 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138594672","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 crucial strategy hasn’t been introduced or implemented widely enough. The present study intended to examine the status of Land Degradation Neutrality (LDN) for the study Rib Watershed, which covers an area of 1585 km2 and is situated in the Upper Blue Nile Basin, Ethiopia. For the past two periods between 2000 and 2020, three indicators, such as Land Cover/Use Changes (LUC), Soil Organic Carbon (SOC), and Net Primary Productivity (NPP) metrics were primarily used to assess the LDN status of the study site. A total of 80 soil samples were then collected from the top 15 cm for six different types of LULC, including cultivated land, forest land, shrub lands, grassland, settlement, and water body. Consequently, land uses land cover matrices, NPP metric, and SOC metrics were also obtained using Land sat images, soil samples, and MODIS satellite images, respectively, for three periods of 2000, 2010, and 2020. Lastly, by integrating the three indicators and using one out all out framework, the status of LDN in the study area was evaluated. The combined findings of the study measurements showed that there was a net loss in cultivated land (123,977 ha), forest land (5623 ha), shrub lands (13984 ha), grassland (11,999 ha), water body (1056 ha) and settlement (1993 ha) for the past two decades (2000 to 2020). For the past two decades, LDN status of the Rib Watershed was generally in a net loss condition. The information delivered by the three sub-indicators is important for experts for the good recognition of their spatial distribution and types of land degradation to attain the LDN targets.","PeriodicalId":29858,"journal":{"name":"Sustainable Environment","volume":"92 25","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-12-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138605954","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}

Data sources such as Landsat images (LULC, NDVI, and LST) and NMAE/KNMI (rainfall) were used and analyzed using ArcGIS 10.7.1, QGIS 2.8.3, and XLSTAT 19. The relationship between NDVI and climate variables was determined using Pearson’s correlation coefficient, while the cellular automata-artificial neural network technique was used to predict future LULC change. Results showed that among the six land use classes, cultivated land gained more than 30%, while grassland lost more than 20% in each decade. The LULC dynamic in the future also showed that bare land and the built-up area had the highest increments, while bush-shrub land had the highest diminishing trends. The NDVI values of each land use class were between −0.14 and +0.74 in 1990 and −0.09 and 0.68 in 2000, respectively. In 2013, the NDVI value ranged from −0.04 to +0.46, and in 2020, it was from −0.08 to 0.55, respectively. The NDVI value of the different land uses showed a decreasing trend. However, LST and rainfall in the watershed showed an increasing and decreasing trend, respectively, which is associated with the LULC daynamics. The correlation between NDVI and LST was found to be negative, whereas the relationship between NDVI and rainfall was positive. Hence, an appropriate use of land is an undeniable fact to minimize the undesirable influence of LULC change on climate variability in the area.","PeriodicalId":29858,"journal":{"name":"Sustainable Environment","volume":"13 1","pages":""},"PeriodicalIF":2.3,"publicationDate":"2023-11-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139269724","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}

Despite the implementation of various SLM measures in Ethiopia, very little is known about whether these measures are effective from adopting farmers’ perspectives. This study examines the costs, benefits, and returns of SLM practices implemented in the Barcha-Adado watershed in Southern Ethiopia. Data for the analysis were obtained primarily from a survey of 231 barley-growing farmers. Using a cost-benefit analytical framework, the returns of SLM practices were evaluated using the net present value (NPV) and benefit-cost ratio (BCR) over the period 2019 to 2046. The major SLM measures implemented by farmers are soil bunds, fanyajuu bunds, and fanyajuu bunds stabilized with grass strips. The average establishment cost of SLM measures was $171 per hectare. On a per-hectare basis, farmers who implemented SLM practices experienced a 28% higher crop yield and an NPV of $1,491.6 compared to non-adopting farmers. The BCR of SLM practices is 5.16, implying that the present value of the benefits is more than five times higher than the present value of the costs of investment in SLM measures. Returns are the highest for fanyajuu bunds and the least for fanyajuu bunds stabilized with grass strips. Study findings suggest that SLM interventions significantly enhance crop productivity and generate considerable financial returns for adopting farmers. The findings would serve as evidence for the local decision-makers and may provide incentives to scale up the benefits of SLM practices to degraded farmlands in the country.","PeriodicalId":29858,"journal":{"name":"Sustainable Environment","volume":"26 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135038308","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}

In particular, the dependence of the landless people on the direct use of communal natural resources for their livelihoods jeopardizes both the resources they depend on and economic opportunities. To overcome such challenges, conservation of communal natural resources through collective action while addressing the food security problem has been described as one of the most appropriate resource management approaches. Thus, this paper explores how the livelihood strategies of landless people influence their willingness to participate in the conservation of natural resources. The study was conducted in five administrative districts in the Tigray region of northern Ethiopia. The findings of this paper are based on the cross-sectional data collected through structured questionnaires from 324 randomly selected landless households. This study extends the previous analyses by introducing a new method of analytical tool, particularly in modeling rural people’s willingness to participate in conservation. The results of ordered probit regression show that a higher level of willingness to conserve natural resources is observed if the household has access to farmland and harness resources generated in protected lands but with no access to artisanal mining and quarries. The study hence concludes that granting landless rural people access to farming activities and allowing them to reap economic benefits generated in protected lands promotes their participation in the conservation of natural resources.","PeriodicalId":29858,"journal":{"name":"Sustainable Environment","volume":"103 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135137996","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 study aims to investigate the relationship between government healthcare financing and carbon emissions and climate change and propose solutions for greener healthcare financing. Quantitative data from 2000 to 2020 were extracted from the WHO and Global Economy databases. The relationship of four variables indicating government healthcare financing to government budget, to total healthcare financing, to GDP, and per-capita with oil investment were investigated using a multiple regression analysis. The analysis included the world’s ten oil-producing countries with the highest oil revenue to GDP. The results showed significant relationships between government healthcare financing to total healthcare financing, to GDP, and per-capita with oil investment among most of the included countries, thereby demonstrating the substantial contribution of OPEC+ to carbon emissions and climate change. The predominant dependence of OPEC+ on oil for financing, with no tangible future transition insight, should make them persistent contributors to carbon emissions and climate change given the considerable publicly financed part of their healthcare systems and the world’s changeable healthcare needs. Thus, oil-dependent countries should strive to free their healthcare financing from oil investment with the environmental harm that this coupling incurs and adopt transformative strategies that expedite the transition to net-zero carbon emissions.","PeriodicalId":29858,"journal":{"name":"Sustainable Environment","volume":"62 13","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135726469","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}

Currently, Arkansas farmers self-regulate crop burning using voluntary smoke management guidelines to reduce community impacts from smoke by ensuring burns take place in optimal conditions. The aim of this study is to identify burned cropland areas and examine human-caused fire PM2.5 emissions and dispersion during optimal burn conditions, specifically within Mississippi County, Arkansas, USA, using two separate methods. During the 2019 harvest season, high-resolution satellite data was used to manually identify burned areas and crop types. The total cumulative cropland burned area in 2019 was estimated to be 7,137 acres (29.03 km2). Burning harvested rice fields accounted for approximately 35% of the total annual PM2.5 emissions from all annual agricultural burning as reported in the 2017 U.S. EPA National Emissions Inventory, while PM2.5 emissions from burning corn fields were only 8% of the total estimated annual PM2.5 emissions. Approximately 43% of annual agricultural burning PM2.5 emissions occurred between 15 August and 23 October in Mississippi County. These high-resolution burned areas were not captured in the standard coarse resolution active fire products. Secondly, during the 2020 fall harvest season, we measured PM2.5 emissions using a Purple Air sensor and modeled smoke dispersion from a planned burn of rice fields following state-level voluntary guidelines. Additionally, the smoke transport model HYSPLIT was deployed to model this planned burn. The HYSPLIT results suggest that smoke disperses into the atmosphere from burns following the guidelines, limiting ground-level human exposure under optimal burning conditions.","PeriodicalId":29858,"journal":{"name":"Sustainable Environment","volume":"37 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135813445","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}
