摘要

土壤侵蚀是埃塞俄比亚一个严重的环境和自然资源问题,对农业生产力构成重大威胁,是土地退化和土壤肥力下降的主要驱动因素之一。研究的重点是评价Wolaita地区Offa wooreda生物物理水土保持结构的有效性。有目的的抽样被用来选择组成这个分水岭的三个kebeles。W/Dekeya、Wareza和Yakima是选定研究区域的三个流域。为了达到本研究的目的,我们分别对504名、325名和442名户主进行了抽样。他们共占被选研究参与者的17%(227人)。那些知道如何保持土壤和水,退化的原因,以及研究区域内自己土地的敏感区域的人得到了优先考虑。缺乏资金、土地面积有限以及各种社会经济和物质条件阻碍了水土保持系统的使用。因此,农民对现有的生物物理水土保持系统有了合理的定位。研究社区的农民知道一些传统的水土保持做法是保护和恢复农田肥力和生产力的一种措施。社区参与鼓励农民参与水土保持实践,对于解决极端贫困、粮食不安全和环境恶化问题至关重要。从研究中,我们建议政府实施具体的覆盖范围和技术,以及非政府组织的纠正干预。

Assessment of the Effectiveness of Biophysical Soil and Water Conservation Structures: A Case Study of Offa Woreda, Wolaita Zone, Ethiopia
Soil erosion is a serious environmental and natural resource issue in Ethiopia, posing a significant threat to agricultural productivity and being one of the principal drivers of land degradation and soil fertility reduction. Evaluating the biophysical soil and water conservation structures’ effectiveness in Offa Woreda, Wolaita Zone, was the focus of the study. Purposive sampling was used to select the three kebeles that make up this watershed. W/Dekeya, Wareza, and Yakima are the three watersheds chosen for the selected study area. To meet the objective of this study, 504, 325, and 442 family heads were sampled. They comprised the overall 17% (227) of the study participants that were selected. Those who knew how to conserve soil and water, causes of degradation, and sensitive areas of their own plots of land in the study area received preference. The lack of capital, a short stretch of land, and various socioeconomic and physical conditions impeded the use of soil and water conservation systems. As a result, farmers have a reasonable position of the current biophysical soil and water conservation systems. Farmers in the study communities are aware of some traditional soil and water conservation practices as a measure to protect and restore the fertility and productivity of their farmlands. Community participation in encouraging farmers to participate in soil and water conservation practices is critical to resolving the issue of cutting-edge poverty, food insecurity, and environmental deterioration. From the study, we recommend that the government implements specific coverage and techniques as well as corrective intervention from nongovernmental organizations.

期刊介绍: Applied and Environmental Soil Science is a peer-reviewed, Open Access journal that publishes research and review articles in the field of soil science. Its coverage reflects the multidisciplinary nature of soil science, and focuses on studies that take account of the dynamics and spatial heterogeneity of processes in soil. Basic studies of the physical, chemical, biochemical, and biological properties of soil, innovations in soil analysis, and the development of statistical tools will be published. Among the major environmental issues addressed will be: -Pollution by trace elements and nutrients in excess- Climate change and global warming- Soil stability and erosion- Water quality- Quality of agricultural crops- Plant nutrition- Soil hydrology- Biodiversity of soils- Role of micro- and mesofauna in soil
