This study is a comprehensive analysis of LULC changes in parts of the Guinea-Savannah through an integrated approach of geospatial procedures. Multi-temporal satellite imagery data sets of four different years, 1990 (Landsat TM), 2000 (Landsat ETM+), 2010 (Landsat ETM+) and 2020 (Landsat ETM+) were analyzed. Built-up area, Agricultural land, Closed savannah vegetation, Open savannah vegetation and Water bodies were LULC categories delineated for Jirapa municipality. The Cellular Automata-Markov (CA-Markov) model was applied to predict the likely changes in LULC in 2030. The study revealed that the most dominant land cover type in the municipality is the Open savannah vegetation as it occupied averagely 45% of the total surface area. Built-up area increased in area coverage by 93% between 1990 and 2020. Agricultural activities, bushfires, deforestation, infrastructural development, and population growth are the main drivers of changes in Agricultural land, Open savannah vegetation, Closed savannah vegetation and Water bodies. The LULC prediction for 2030 showed that the Built-up areas would increase significantly in 2030 leading to a 6% reduction in Agricultural land in 2030.","PeriodicalId":500108,"journal":{"name":"Journal of Environmental Geography","volume":" 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141677575","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 this study, the mixed methods research design is used to examine the implications of water sector climate change response strategies (CCRS) on SDGs in Mutirikwi sub-catchment in Masvingo, Zimbabwe. Results show that the climate is changing, with a statistically significant (p = 0.031; α = 0.05) increase in the annual mean temperature and a declining rainfall trend, though not statistically significant (p=0.753; α = 0.05). Views from local communities and stakeholders confirm the existence of climate change. There is a deluge of response strategies to the changing climate, including borehole drilling, roof rainwater harvesting, surface storage, water reuse and water transfers. These strategies have directly contributed to the achievement of SDG 6 (Clean Water and Sanitation), SDG 11 (Sustainable Settlements), and SDG 13 (Climate Action). They have also indirectly contributed to the achievement of SDG 3 (Health), SDG 5 (Gender), SDG 9 (Infrastructure) SDG 12 (Sustainable Consumption) and SDG 15 (Life on Land). The study concludes that there is an inextricable link between CCRS and SDGs. However, implementation of the response strategies is riddled with challenges that are threatening the sustainability matters. There is a need to design community-driven response mechanisms synergized with national and international climate adaptation initiatives to ensure sustainability of the strategies through guaranteed policy and resource support from the national government and non-governmental agencies.","PeriodicalId":500108,"journal":{"name":"Journal of Environmental Geography","volume":"28 9","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139382962","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 Europe, billions of liters of distillery waste are generated annually and its eco-unfriendly disposal can cause severe environmental and health impacts. Composting is a viable management strategy to treat and manage distillery slop promoting the recycling and stabilization of organic matter and nutrients in the material. The review examines different composting methods, such as single composting, co-composting and vermicomposting, along with their benefits and drawbacks. To optimize composting effectiveness, various materials, such as sewage sludge, vinasse, green and animal manure, inorganic amendments, bagasse, filter cake and municipal solid waste, among other agro-food and animal bio-wastes, can be used as a source of nitrogen and microorganisms. Also, the usage of different materials and mixtures aims to enhance the composting process increasing the degradation rate and the quality of the compost. The challenges of distillery spent wash composting are also covered in the paper which are mainly due to its characteristics, including high salt content, low carbon-to-nitrogen ratio, low pH and potential phytotoxicity. The paper concludes that composting distillery spent wash is an effective and sustainable waste management solution for recovering valuable nutrient resources and producing a stable nutrient-rich organic soil amendment. The produced compost can improve crop yields, nutrient absorption by plants and plant biomass and contribute to soil properties and restoration. The review provides insights into the current state of distillery spent wash composting and recommends future research directions to improve efficiency and expand potential applications.","PeriodicalId":500108,"journal":{"name":"Journal of Environmental Geography","volume":"17 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139383996","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 its importance, the species faces conservation problem. This study evaluated the effect of climate and habitat on morphological characteristics and fruit production of P. nitida . A total of 132 fruiting trees was randomly sampled from three habitat types (home gardens, botanical garden and natural forest) and three soils (Nitisols, Arenosols and Acrisols) in Dahomey Gap and Guineo-Congolese zone. A total of 5 morphological traits and fruit production were recorded per tree to describe the relationship between morphological determinism of the species and climate. Pearson correlation was performed to identify the suitable habitat type in each climatic zone. Harmonized World Soil Database was used to determine physicochemical characteristics of the soil types on which the species occurred. Results revealed that the climatic zones (p<0.001) and habitat types (p<0.0001) influenced significantly the morphological characteristics and fruit production of P. nitida. High trees with more number of fruits were observed in home gardens on acid soils (Nitisols (pH: 5) and Arenosols (pH: 5.3)) in Dahomey Gap. In Guineo-Congolese zone, the species was more present in natural forest on acid Acrisols (pH: 5).","PeriodicalId":500108,"journal":{"name":"Journal of Environmental Geography","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135088417","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}

There is actual question what kind of connection could be shown between the rate of soil erosion, land cover categories and hemeroby levels? How can the intensity of antropogenic effects influence the rate of soil erosion? We did some research work in the North Hungarian Region, in Cserépfalu in 2014. In Cserépfalu, the northern areas are under nature conservation and belong to the Southern Bükk Mountains while the southern dissected pediment is the extensive agricultural territory. We described the soil types in the southern areas using the soil description method of FAO. We collected data about the rate of soil erosion, the land cover types, slope angle, slope forms, slope aspect and data for the relief conditions too. We could point out the sheet erosion around the 15 investigated soil profiles and we could found 3 strongly eroded, 8 medium eroded and 4 accumulated soil profiles. The land cover categories were given based on FAO category system and topographic map from 1990. Our results showed that land cover categories were changed in time and it caused the change of hemeroby levels as well. The intensity of land cultivation in investigated areas was changed. We could point out in some cases that the stronger soil erosion rate was caused by former land cover system. In summary, some former agricultural areas were changed and became as an abandoned areas so that the antropogenic effects were decreased in extensive agricultural areas in Cserépfalu. Our results can be compared with another pediments dissected by valleys where extensive agricultural areas are characteristic in Hungary.","PeriodicalId":500108,"journal":{"name":"Journal of Environmental Geography","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135017636","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}
