The Ethiopian economy, largely reliant on the pastoralist system, is significantly impacted by its use in semi-arid regions, ensuring livelihoods and export markets. The study aims to assess the strengths, weaknesses, and overall impact of these initiatives on pastoral communities. Moreover, it explores the resilience factors exhibited by these communities, identifying cultural practices, adaptive strategies, and community-driven approaches contributing to their ability to withstand challenges. ...

Vermifilter, based on earthworm-microorganism synergistic action, could simultaneously achieve the reduction and stabilization of excess sludge environment-friendly. To make vermifilter work more efficiently and steadily, the diameter of ceramsite, filter height, and influent concentration were investigated in this study. The results showed that though larger ceramicite may decrease the rate of suspended solids (SS) reduction and volatile suspended solids (VSS) reduction slightly, it can improve...

Protected areas (PAs) are managed for sustainable conservation of natural resources. While local adjacent communities are dependent on natural resources, there is limited access to the resources in PAs. Hence, debate on the role of PAs in improving local community’s livelihoods often gives rise to conflicts. Solutions to this debate have been hampered by lack of information on the actual community concerns. To address the challenges, focus group discussions (FGDs) were done to identify local com...

EDTA synthesized activated carbon derived from sawdust, was utilized as adsorbent for the removal of Pb(II), Cd(II) and Zn(II) ions from aqueous solutions. The adsorptive characteristics and elemental composition of this activated carbon were studied using SEM and EDX techniques respectively, the analysis revealed that SAC-EDTA contained 71.95% by weight of carbon contents which are requisites for the high adsorption capacity. The effect of initial metals ions concentration, adsorbent dose, cont...

Management of wildlife species has recently become a global concern as most are threatened to near extinction or endangered. The establishment of national parks such as the Sapo National Park (SNP) in the 1980s as a conservation area has been found as one of many solutions for protection of wildlife species in Liberia. Nonetheless, due to various natural and anthropogenic drivers and pressures, the SNP is under consistent threat of losing its biodiversity integrity. Various factors including wea...

Diclofenac (DCF) is a non-steroidal anti-inflammatory drug (NSAID) used to relieve pain in joint-related diseases. It is not completely metabolized after consumption and cannot be easily removed using conventional wastewater treatment. DCF has been detected in water bodies and may pose chronic effects on the endocrines of living organisms even at low-level exposure. Heterogeneous photocatalysis provides an alternative and efficient method of degrading DCF. In this study, the photocatalytic remov...

Wild populations of stingless bees in Costa Rica present a valuable information gap in terms of wild ecology, due to the great difficulty that national parks and biological reserves represent to carry out population studies due to their great exemption. Due to this, the meliponarium and rescue projects of these bees provide an important opportunity for their study since they bring together local wild populations in the same physical space. In Costa Rica, there are several types of Wildlife Manag...

This research aims to highlight the effect of human activities and speculative fishing on the dynamic of Tiko mangrove landscapes. The study is based on the collection of bibliographical and factual data (field observations, botanical records) and the diachronic analysis of satellite images of the locality over the past five decades. The NDVI method was used to illustrate the dynamics of land use between 1976, 1986, 1996, 2006 and 2016. Botanical surveys were carried out in three transects 100 m...

For several decades, many households in rural areas have relied on surrounding forests for their livelihoods, safety nets and sustenance. This reliance is most often determined by the household’s characteristics, available forests and economic benefits. That notwithstanding, the demand for more farmlands and unsustainable harvesting of forest resources are pushing these forests into depletion. This rapid decline endangers the livelihoods of forest-reliant households, threatens biodiversity and i...

In Uganda, sorghum constitutes the second most widely grown cereal according to the latest statistics from the country’s statistics body, the Uganda Bureau of Statistics. This notwithstanding, there has been, in the context of Uganda, very little research and published literature on its potential to sequester carbon. There is no sufficient data on the exact levels of carbon sequestered by this sorghum/legume intercropping system, which is widespread as a technology within Uganda’s smallholder so...
