Abstract. Land degradation resulting from improper land use and management is a major cause of declined productivity in the arid environment. The objectives of this study were to examine the effects of a sequence of land use changes, soil conservation measures, and the time since their implementation on the degradation of selected soil properties. The climate for the selected 105 km2 watershed varies from semi-arid sub-tropical to Mediterranean sub-humid. Land use changes were detected using aerial photographs acquired in 1953, 1978, and 2008. A total of 218 samples were collected from 40 sites in three different rainfall zones to represent different land use changes and different lengths of time since the construction of stone walls. Analyses of variance were used to test the differences between the sequences of land use changes (interchangeable sequences of forest, orchards, field crops, and range), the time since the implementation of soil conservation measures, and rainfall on the thickness of the A-horizon, soil organic carbon content, and texture. Soil organic carbon reacts actively with different combinations and sequences of land use changes. The time since stone walls were constructed showed significant impacts on soil organic carbon and the thickness of the surface horizon. The effects of changing the land use and whether the changes were associated with the construction of stone walls, varied according to the annual rainfall. The results help in understanding the effects of land use changes on land degradation processes and carbon sequestration potential and in formulating sound soil conservation plans.

People’S Perceptions

The land use of the Belihuloya catchment area in Sri Lanka has been changing over a long period mainly due to the human activities. The study was aimed to find out the spatial and temporal changes of land use in the Belihuloya Mini Catchment area of 1956 to 2015, and obtain the local people's perception of the effects of land-use changes in Belihuloya. To study the people's perceptions of land use change, a questionnaire survey was conducted among randomly selected 180 households. Aerial data of 1956 and satellite data of 2015 were used to analyze the land use changes. The vegetation cover maps of 1956 and 2015, demonstrated the drastic changes of land use in Belihuloya. More than 50% of the respondents in the study area perceived that the land use has been changing due to the construction activities, forest fires, illegal loggings, pine and tea cultivation and the expansion of built-up areas. The deforestation has badly effected on water resources in the Belihuloya. The reforestation programs, including community-based reforestation programs can be introduced to minimize the impacts. It is necessary to implement existing legal frameworks with supports of different stakeholders to conserve the Belihuloya.

Modelling of the effects of land use changes on flood hydrograph in a small catchment of the Płaskowicka, southern part of Warsaw, Poland This study concerns the influence of urbanized trend affected on the flood hydrograph in a small catchment in Warsaw. Based on recorded events a selected procedure for simulation rainfall-runoff process has been accepted for flood estimation. The Soil Conservation Services Curve Number method (SCS-CN) and empirical formulae for Nash model parameters, developed by Rao at al. were used to analyze the nine selected events from 2007 to 2009. The analysis confirmed usefulness of the selected procedure, implicated in a home developed computer program, for estimating flood hydrographs as responses of the small urban catchment to heavy rainfall events. Flood hydrographs were estimated for three various stages of land use. The results demonstrate that the peak flood flow would increase over eight times due to urbanisation of the catchment.

Effects Of Land Use

Distributed physically-based models have the predictive capacity to assess the effect of land use changes on groundwater dynamics across a range of scales. MIKESHE, which represents state-of-art of distributed hydrological model, is applied to the Skjern catchment. It is utilized to evaluate hydrologic impacts of land use changes in a watershed. Our overall objective was to quantitatively evaluate the effects of land use changes on watershed hydrology within the 1175 km2 Skjern catchment in Denmark. The results show that the soil is unsaturated and has bigger storage capacity. The groundwater recharge distribution has seasonal characters like the runoff, which mainly concentrated in winter and spring and decreased in summer and autumn.
