Results obtained from calculated water quality index (WQI) showed that the drop in Lake Nasser water's levels led to a decline in the water quality of the Lake and Abu Simbel Khor, from the order of good (period of flooding) to medium (period of receding water). This impact may in turn influence the whole Lake due to water rebounce from the Abu Simbel Khor, to the main channel. Total dissolved solids (TDS), biological oxygen demand (BOD), turbidity and recognizable depletion in dissolved oxygen (DO) were observed in sewage station and affected on Lake Nasser water area adjacent seepage water area. Pollution from total and fecal coliforms as well as fecal streptococci didn't exceed permissible limits except for sewage station basin that discharge agricultural and sewage wastes are the key factors in this environmental problem, particularly in period of receding water. Therefore, it is further concluded that the Abu Simbel Khor, could be considered as potential pollution sources during low water levels of the lake.","PeriodicalId":186239,"journal":{"name":"Journal of Ecology & Natural Resources","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130527018","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}

Water scarcity in general and water quality in the particular region, are posing risks to sustainability and quality of life. Indian economy and agricultural practices depend on its rivers, as per an estimate about 80 percent of fresh surface water and 60 percent of ground water have been used by the agricultural sector, but rivers and other water bodies are facing problems of contamination due to domestic waste, sewage, agriculture effluents of chemical fertilizers and discharge of industrial effluents. Domestic waste is drained out as waste and ends up flowing into various water bodies which leads to pollution of water sources. The careful utilizing of river water is the biggest challenge. Losses are also due to traditional way of irrigation which increases the problem of water scarcity. For sustainability of livelihood and maintaining quality of life, it is essential to have sufficient water availability even in the phase of climate change. The national drinking water programme and accelerated urban water supply programme aim to provide universal and equitable access to safe and affordable drinking water for all by 2030. It is time to value every drop of water and rejuvenate our traditional water bodies, clean rivers, recharge ground water, collect rain water and successful implementation of technology for achieving water resource management.","PeriodicalId":186239,"journal":{"name":"Journal of Ecology & Natural Resources","volume":"81 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130678456","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}

Community involvement and stakeholder participation became important components of development and natural resource management, prompting developing countries to undertake decentralisation reforms by the 1990s. The reforms aimed to encourage participatory development, local empowerment and poverty reduction, democratisation, and resource sustainability. Their performance has, however, been mixed. Decentralisation efforts have suffered in situations where powerful actors, through various strategies, have managed to retain control over natural resources, obstructing power transfers to the communities. This has resulted in Responsibilisation, which is the transfer of responsibility to local communities without the transfer of requisite power. Responsive, collaborative governance is crucial in efforts to avoid responsibilisation. This refers to governance that devolves responsibilities and powers together, providing the requisite capabilities and support, enabling appropriate management decisions and actions at the devolved levels. Polycentric governance is crucial towards this end. Participatory Forest Management, a modality of Community-Based Forest Management, has been practised in Kenya since the Forest Act of 2005. This paper looks at forest polycentric governance institutional structures with cross-level interactions and representation bodies at each level of forest governance for successful social and ecological outcomes. This paper's product is a proposed forest polycentric governance institutional structure for better social and ecological outcomes in Kenya, which can be generalised to broader cases.","PeriodicalId":186239,"journal":{"name":"Journal of Ecology & Natural Resources","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131018947","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}

Previous studies have focused more on climate variability in relation to agriculture and water resources, with little or no insights into highland rangeland ecology. These shocks add to the common pool rangeland security issues with unsecure pastoral tenure, land grabbing, rangeland degradation, poor land use planning, dwindling range resources, amongst others. Rainfall data was collected from 13 stations covering the region to understand the climate trend. The Standardized Precipitation Index (SPI) was used to the recurrence of meteorological droughts, vis-à-vis transhumance. Results show discernable impacts of climate variability on the pastoral landscape especially related to prolonged dry seasons, pasture scarcity, poor land use practices notably seasonal bush fires, stocking densities and overgrazing. Indigenous knowledge identified pasture scarcity, weed invasion, poor range products, cattle mortality, degradation, land use conflicts, dwindling water resources as related effects. Due to these growing difficulties within the grazing landscape, pastoral communities have resorted to growing partnerships with development agencies to develop more resilience as a result of past challenges grappling with the nefarious effects of climate change. Cultivating improve pastures, fodder crops, developing water schemes and adjusting the grazing calendar are some adaptation measures. Technical and financial resources need to be transferred for risk mitigation and building capacities to reduce the vulnerability of pastoral communities for a sustained future.","PeriodicalId":186239,"journal":{"name":"Journal of Ecology & Natural Resources","volume":"520 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116335764","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 order to achieve the goal of advancing to the middle and high end of global value chain and \"dual carbon\", at the same time to achieve the win-win situation of global value chain embedded and carbon emission reduction, it is of great theoretical and practical significance to play the coupling and coordination role of the two. Based on the theory of coupling coordination, this paper constructs the evaluation index system of global value chain embedded and carbon emission reduction system, and analyzes the development status of global value chain embedded and carbon emission reduction in 21 sub-sector industries from 2005 to 2014. The results show that most industries are in the moderate coordination stage, and the lag of global value chain is the key factor restricting their coordinated development. Labor-intensive industries have the best coupling coordination degree, forming a situation of mutual promotion of development, followed by technologyintensive industries and labor-intensive industries. Therefore, improving the level of green technology, breaking through the technological blockade and improving the position of Chinese industries in the global value chain are conducive to forming a positive interaction between the two.","PeriodicalId":186239,"journal":{"name":"Journal of Ecology & Natural Resources","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114663288","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}

Shaki (ETBW9089) variety was selected from the international nursery which was introduced from CIMMYT in 2015 and tested together with 50 other test genotypes including local and standard checks at a quarantine site in Ethiopia. The variety was mainly selected for best agronomic performance, wide adaptability, resistance to disease, and high yield potential. Shaki is adapted within the range of altitude 1900‒2780 masl with annual rainfall amount receiving from 640‒1290 mm. The new bread wheat variety Shaki is high yielding variety across wide environments. Shaki is a stable and adaptable wheat variety for different bread wheat-growing agro-ecologies of Ethiopia. Shaki variety produced 13.36% and 12.68% grain yield advantage over the standards checks Wane and Lemu, respectively. Shaki variety showed relative resistance to stem yellow and leaf rust as compared to wheat varieties under production at the medium to high land wheat-growing agro-ecologies. The genotype with pedigree name BABAX/LR42// BABAX/3/ER2000/4/BAVIS and selection history CMSA09M00434S-050ZTM-0NJ-099NJ-3RGY-0B was named Shaki after official release for commercial production by the national variety releasing committee in 2021. Replacement of susceptible bread wheat varieties and availing more alternatives bread wheat varieties to grow for resource-poor farmers is very crucial in the region.","PeriodicalId":186239,"journal":{"name":"Journal of Ecology & Natural Resources","volume":"46 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134205728","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}
