The Benggaila watershed disembogues into Kendari Bay, the upper part was dominated by forest areas and the middle and downstream parts were dominated by residential areas. Its location in the capital city of Southeast Sulawesi causes a very high change in land use and social culture in the watershed. This study aimed to determine changes in land use and community socio-cultural activities in the period 2004 to 2019. The results showed that changes in land use during that year range were very high. Changes from agricultural land and forest to the settlement were 67.4% dominate the other changes. This condition causes a shift in the socio-cultural pattern of society. The people of origin who lived in the downstream and middle of the watershed were moved to the upstream, while the immigrants stayed downstream of the watershed. These changes have also changed the patterns and methods of farming as well as behavior in utilizing forests. Soil and water conservation efforts were carried out by integrating changes in land use and the current social conditions of the community through adequate land planning and the community's mindset in utilizing the land.

Abstract Hazardous land conversion in the Padang watersheds harms the hydrological conditions of the watersheds. Land use without considering the capacity and carrying capacity of the land results in decreased land productivity and increased watershed damage. This study aims to recommend directions for land use and land management in the Padang watersheds in areas that have a high and very high level of land conversion vulnerability. Analysis of land conversion vulnerability obtained by spatial modeling using ArcGis 10.3 software. The land cover data used in this study are data from the Ministry of Environment and Forestry in 2000 and 2019. Directions for land use are carried out through literature review in scientific journals, activity reports from both government and non-government agencies. Recommendations for land management directions are differentiated for urban areas and non-urban areas. Shrub cover that is vulnerable to conversion so that reforestation or other productive land uses are carried out with attention to soil and water conservation. Secondary dryland forest cover that is very vulnerable to conversion for partnerships with communities through community forestry/agroforestry schemes, rehabilitation and reforestation, and ecotourism. Plantation cover that is vulnerable to conversion can adopt an intercropping pattern of garden crops and seasonal crops. Agricultural land cover of dry land with high conversion vulnerability can adopt perennial crops at the land boundary and apply soil and water conservation. Residential areas in rural areas can adopt tree planting and make infiltration wells. The management direction for residential land in urban areas is to apply water conservation techniques (infiltration wells and polders) and arrangement of residential areas.

Soil and water conservation (SWC) is being advocated as an integral part of agricultural land management as it not only controls/minimizes soil erosion but also restores/rehabilitates the degraded lands. The purpose of this study was to evaluate the impact of soil and water conservation practices in improving soil fertility in the agricultural landscapes of the Damota area, southern Ethiopia. Forty-eight soil samples (both disturbed and core samples) were collected from the conserved and adjacent nonconserved plots. The significance analysis test was performed using analysis of variance. The result of the study showed that higher mean values of soil physicochemical properties were observed in the conserved plot than its nonconserved counterpart. The mean differences of organic carbon, total nitrogen, cation exchange capacity, and exchangeable K+ and Ca2+ between conserved and nonconserved plots were statistically significant at the P < 0.01 level. Besides, available phosphorous and bulk density were significant at P < 0.05 , but the effect of SWC practices was not found significant on soil texture, soil pH, and exchangeable Na+ and Mg2+ content of the soil in the Damota area. Community-based soil and water conservation practices have improved the soil fertility in agricultural landscapes, although significant results have been observed in some fertility indicators. Therefore, strengthening the implementation of conservation measures by participating in all stakeholders is recommended. Supporting physical structures by agronomic and vegetative measures and continued maintenance can bring better results.

Erosion in the watershed generally occurs due to land use that ignores the rules of soil and water conservation. There is much activity carried out by people living on land in the Yeh Leh watershed area, which makes the level of dependence is very enormous.The erosion forecast is using the USLE (Universal Soil Loss Equation) to estimate the erosion swift occurs and to obtain illustration in determining the precise soil and water measures in a region. The determination of land capability classification is using Arsyad’s method (1989) in which to classify the land ability by classifying the land ability class based on the value of land limiting factors, which then adjusted to the criteria of classification of land capability. The land use directional determination is applying the scoring method where combining field slope factor, soil sensitivity to erosion and daily rainfall intensity. The erosion level of the YehLeh watershed area is categorized as mild to very severe. A very light erosion level as large as 515 ha (21.01%), with the land use in the form of irrigated rice field and forest. The severe erosion level as large as 990.02 ha (40.40%) with land use in the form of plantations. The very heavy erosion level as large as 945.82 ha (38.59%) with land use in the form of plantations. The classification of land capability in the YehLeh watershed area consists of 5 classes of land abilities: class II of 115, 22 ha (4.70%), class III of 533.95 ha (21.79%), class IV of 423.61 (17.28%), Class VI of 1,102.03 ha (44.97%), and Class VII of 276.03 ha (11.26%), with some limiting factors for instance, soil texture, erosion and drainage. Proposed land use in the YehLeh watershed area use for forest areas is as protected forest of 456.49 ha (18.63%). Proposed land use outside of the forest area consist of 58.51 ha (2.39%) of seasonal crops, annual cultivation area of 990.02 ha (40.40%) and buffer area of 945.82 (38.59%). Keywords: watershed, erosion, land capability classification, proposed land use.

Rainfall is a major dynamic source of soil erosion and nutrient loss on slopes. Soil and water conservation practices and agricultural activities can change the soil surface morphology and thus affect erosion and nutrient losses. This study focused on the effects of several typical soil and water conservation practices and agricultural land, for the purpose of: (1) determining how these practices prevent erosion and nutrient loss and identifying the hydrodynamic mechanisms; and (2) determining the application conditions for different practices. Runoff, sediment, total nitrogen (TN) and total phosphorus (TP) in fish-scale pits, agricultural land, narrow terraces, shrub cover and bare land, under rainfall events in rainy seasons (from May to November) during the 2010–2015 period, were monitored. Slope hydrodynamic mechanisms and application conditions of these practices were also investigated. The results showed that compared with bare land, fish-scale pits performed the best in preventing runoff, sediment, TN and TP, followed by 30% shrub coverage, narrow terraces and agricultural land, successively. Total runoff, sediment, TN and TP losses in fish-scale pits site were 19.70%, 2.03%, 10.10% and 35.97% of those in bare land of the same area, respectively. Soil and water conservation practices could change the hydraulic characteristics of slopes, decrease Re (Reynolds) and Fr (Froude) numbers, thereby decreasing runoff, sediment, TN and TP losses. Fish-scale pits were suitable for the areas with small single rainfall and good water permeability. When rainfall was greater than 60 mm, narrow terraces had highest efficiency in reducing sediment loss; therefore, they were suitable for the areas with relatively high rainfall intensity and soils similar to the sandy loams of the study area. As to the practice of covering land with plants, the effect was sustainable due to the plants’ long-term growth. Agricultural land was not recommended since the losses on it were relatively higher due to the impact of human activities. In reality, these practices may be applied in combination so as to effectively control water, soil and nutrient losses.

Telagawaja Sub-Watershed is upper part watershed of Unda Watershed. As upper watershed, Telagawaja sub watershed has functions as conservation area, water catchment area, and managed in order to keep sub watershed environment not degradated. This research objectives are to identify the characteristics of the land, the function of the area, and the erosion potential rate (TBE), as well as land management recommendations on Telagawaja Sub-Watershed. The identification of land is conducted by analyzing the characteristics of thematic maps in study area. The directives of classification land function is determined by the Minister of Agriculture Number.837/Kpts/Um/ 11/1980 and Number: 683/Kpts/Um/8/1981. The prediction of actual erosion is calculated by USLE formula for the agriculture area, while non-agricultural land use is applied Snyder formula (1980) in Asdak (2010). Erosion class and erosion rate (TBE) are determined based on the Director General of Reforestation and Land Rehabilitation Department of Forestry Number.041/Kpts/V/1998. Determination for the amount of erosion is still can be allowed using the method of Thompson (1957) in Arsyad (2010) which based on soil properties attached to Telagawaja sub watershed. The research shows that Telagawaja Sub-Watershed characteristic is an area which is susceptible to erosion.The analysis shows that the direction of the area function Telagawaja sub-watershed consists of an area of 7337.28 Ha of protection forest (66.01%), and the function of a buffer area 3.778.31 Ha (33.99%). The result of the study on Telagawaja sub-watershed erosion is 2777.07 tonnes ha-1year-1. Erosion class and erosion rate of Telagawaja Sub-Watershed vary from very light to very severe. Erosion class and erosion rate (TBE) with category severe to very severe consist an area of 2.071,97 ha (18,64 %) from total sub-watershed area. Land use planning implemented by applying alternative measures of soil and water conservation can reduce the rate of erosion of 2777.07 tonnes ha-1year-1 to 611.00 tonnes ha-1year-1 or less 2166.07 tonnes ha- 1year-1.
