Abstract: Biodiversity and the ecological environment are two interconnected elements of nature that help sustain the balance of life on Earth through various complex interactions. They are important parts of the natural world and offer many advantages to both people and the environment. Management and conservation of biodiversity involves protecting and maintaining biodiversity to ensure sustainable benefits for both current and future generations. Biodiversity is declining, and there are significant environmental changes occurring due to various human and natural influences. As a result, various significant economic, ethical, and aesthetic benefits have decreased. The primary goal of this review was to comprehend the importance of biodiversity conservation and management in preserving ecosystem balance by examining various research materials. Recent publications were gathered from Google Scholar and the Web of Science, and a systematic review was conducted to explore the topic. Discussions with colleagues and friends were also key methods used in addition to the systematic review. In the next few years, research articles are likely to show a significant increase in the number of threatened species and the seriousness of their extinction risks. Additionally, the connections between sustainability, management, and biodiversity conservation are not yet clearly defined from a research standpoint. It is important for professionals in Ecology, Biodiversity and Conservation, as well as Environmental specialists, to communicate effectively.

Abstract: Soil erosion is a very chronic environmental issue in the agricultural sector in Ethiopia. This study's objective in the Semen Bench district is to assess the perception of farmers on soil erosion and sustainable land management (SLM) practices. The study used a multi-stage sampling method. 124 sample households were selected by systematic sampling techniques. The Likert scale and descriptive statistics were used to analyses the data. Perceived consequences of soil erosion were loss of soil fertility (79%), yield reduction (82.3%), decreased soil depth (50.8%), formation of rills and gullies (45.2%), and soil color change (33.9%) on their farmland, respectively. The results showed the significance of SLM practices, with 32 and 56% of respondents strongly agreeing and agreeing that households could control soil erosion, respectively. The farmers implemented different indigenous and introduced practices to minimize soil erosion and improve soil fertility. The common indigenous SLM practices were contour farming, intercropping, agroforestry, and crop rotation, while introduced practices included stone bunds, fanyajuu terraces, cut-off drains, trenches, bench terraces, and area enclosures, as well as planting different seedling species and Vetiver grass. It can be concluded that SLM is crucial for minimizing soil erosion and improving crop yield. Based on the results, recommendations should focus on encouraging farmers and creating awareness about the application of integrated modern SLM practices.

Abstract: Background: Ethiopia is the largest among the horn of African countries which has suffered from deforestation, land degradation, soil erosion, weak land management, low standard of constructed physical structures, unskilled human power and insufficient agricultural productivity problems caused due to anthropogenic activities.. Even though the government of Ethiopia launched an ambitious program of soil and water conservation efforts supported by donors since the 1973, the results of the effort are not as expected, the reaction undertaken to overcome has remained too weak, local communities are still under food insecurity and the problems are continued as a critical constraint for the country. Objective: This study, therefore, aims to examine the impact of improved physical structures on crop yield and household’s annual income based on the data of 2023 and 2024 harvest years. Method: The data was collected from a survey of 252 total household head farmers of which 132 were improved soil and water conservation structure users while 130 were non-users. Household head respondents were selected using simple random sampling techniques. The statistical data were analyzed using chi-square, t-test and SPSS 20 software. Focus group discussion, key informant interview and personal observation were also held to gather qualitative data. The key finding: The finding showed that adoption of improved physical structures has a significant contribution in crop yield and farmers’ annual income. About 66.6% of the implemented physical structures were found to be below the recommended standard. Conclusion: overall, the study concludes that adoption of improved physical soil and water conservation structures should be expanded and continued in the study area.
