“…These practices deteriorate basins in a systematic way, affecting the quality of life of rural communities, as well as the water supply for urban areas [22,23]. To address this problem, the literature focuses independently on the physicochemical, bacteriological, or biological characteristics of water through the analysis of spatiotemporal variations in water quality [24,25], which are aligned with policies that aim at guaranteeing water supply in adequate quality and quantity as well as access to water, sanitation, and hygiene (WASH) for citizens around the world.…”

Conventional agricultural practices, such as the use of agrochemicals, implementation of monocultures, and the expansion of crops in strategic ecosystems, have significant impacts in Andean basins, directly increasing nutrient inputs to waterways, and contributing to ecological fragility and socioeconomic vulnerability. This complex dynamic is related to land-use change and production activities that affect the provision of hydrological ecosystem services. This study presents an integrated analysis of socioecological interactions related to water quality in the Las Piedras River basin (LPRB), a water supply basin located in the Andean region of southwestern Colombia. The analysis was conducted over a five-year monitoring period to assess the spatiotemporal variation and correlation of water quality between streams and agricultural runoff water within the LPRB. Furthermore, water quality indices were calculated based on physicochemical and biological parameters to evaluate the impact of land-use/land-cover changes and agricultural activities within the basin. Results demonstrate that different types of actors, productive logics, mechanisms of use, and access to water within the basin affect water quality and uncertainty for water management, while facing socioecological conflicts between actors.

Soil is an important part of agriculture applications. An understanding of physical and chemical condition of any soil is essential for proper implementation of the other soil management practices. Therefore the physico-chemical study of soil is very important because both physical and chemical properties which affect the soil productivity. This physico-chemical study of soil is based on various parameters like pH, electrical conductivity, moisture, soil organic matter, and soil organic carbon. This knowledge will create awareness among the farmers about economic productivity. In this study the physicochemical properties of soil samples obtained from Tepi campus was determined. Their value could be pH 6, Electrical conductivity 7.31µS/m, moisture content 5.038%, organic matter content 4.1% and organic carbon content 3.3%. Physical and chemical properties listed above indicate that this soil sample is productive and suitable for agricultural use. Based on the result in this study soil sample in the Tepi campus garden is slightly acidic, wet, and high organic matter content. Most of the south western parts of Ethiopia get high rain fall through the year more than eight month and its forest area. This makes the soil in this area high moisture content and organic matter content. Corn, maize, sugar cane and coffee are the most cultivated crops in this area.

Climate change is a pressing challenge globally, which needs adaptive strategies. This research was conducted to evaluate the role of soil and water conservation practices (SWCPs) as climate change adaptive strategies. The study was conducted in the northwest highland of Ethiopia that represents areas with high rainfall and high degradation. The effects of SWCPs were compared on cultivated farms and ex-closures. Sufficient soil samples and crop yield were collected to evaluate the performance of SWCPs to climate change adaptive mechanism. A total of 27 disturbed composite and 27 undisturbed soil samples at a depth of 0-20 cm were collected on cultivated land treated with different soil conservation practices along with 27 wheat yield samples. Similarly, 36 undisturbed soil samples at 0-15 and 15-30 cm were collected from ex-closure and adjacent grazing land. Collected data were subjected for the analysis of variance (ANOVA) for their significant differences followed by the mean separation for the treatments that showed significant difference using least significant difference (LSD). The result showed that SWCPs improved soil physico-chemical properties including soil organic carbon as well as wheat grain yield. Degraded grazing lands rehabilitated and resulted large stock of soil organic carbon by management interventions. Therefore, rehabilitation of degraded cultivated and grazing lands through SWCPs was found to improve soil properties, grain yield, and stock soil carbon and could be recommended as a climate change adaptive strategy.
