“…The results show an indirect correlation between the growth and development of denser plants with the incidence of erosion [46][47][48]. This opinion is supported by [49][50][51], which identified ground cover as a key element in controlling land and water loss. Therefore, securing higher quantities, particularly comprising broadleaf trees is recommended.…”

The Land converted in the form of road construction crossing protected forest areas has resulted in the loss of vegetation diversity and while surface flow and erosion are accelerated. This research aimed at determining the effectiveness of land and water conservation practices in controlling runoff and erosion. The research method adopted in this investigation uses a multislot divider measuring 10 m x 5 m with a slope of 25% on geogrid, geonet, and vegetation cover plots, where each plot comprises 3 pieces, accumulating to 9 units. The result showed the highest total runoff between June and November in the geogrid plot (531.61 m 3 /ha). This was followed by the geonet (492.5 m 3 /ha), while the lowest value was recorded in the vegetation cover plot (174.7 m 3 /ha), with 1336 mm of rainfall. These outcomes collectively had a directly proportional relationship with the total land erosion, and similar rainfall at 94.17 tons/ha, 73.9 tons/ha, and 42.4 tons/ha for geogrid, geonet, and vegetation cover plots, respectively. The results demonstrated the effect of rainfall and slope on runoff as well as erosion and also provide valuable information on the negative impact of land conversion from vegetation cover to other uses.

“…Spatial modelling and layer arrangement has been prepared in GIS environment [58,59] by introducing the type of land use, its importance, the geological, geotechnical and earthquake properties of the study area. The objective of this model is to minimize the susceptibility to earthquake hazard in the Miri district for future earthquakes.…”

The objective of this research is to develop the framework for sustainable land-use planning on the basis of seismic microzonation to reduce the devastating effects of future earthquakes by utilizing the software geographical information system (ArcGIS). Miri district of Sarawak in Malaysia has been chosen as the study area because of having the highest peak ground acceleration which is 0.09g in terms of the 10% probability of exceedance in 50 years. In addition, the frequency of an earthquake with a magnitude up to 5.3 is approximately every 5-7 years. Therefore, it is vital to introduce land use planning in order to diminish the adverse effects of earthquakes in the future. For this purpose, Google Earth Pro was used for the collection of satellite image data for land use planning purposes. From the results, it was found that the seismic hazard in the Miri district varies from low to high corresponding to 2475 years of return period with low to moderate as predominant over the Miri district. Only a few areas are under high hazard. Also, the land use planning map was compared with the current land use map acquired from satellite imagery and it was found that all built-up is in the low hazard area. It is envisaged that the findings from this research will contribute immensely to the literature that will serve as background information and a guide for analysts, disaster management, engineering designers and seismologists in Malaysia and the world as a whole.

“…Support practices factor (P) is a land management practice to reduce erosion such as contour farming or terracing on steep slopes with agricultural land, or it can be expressed differently to reduce the runoff rates [Eisenberg and Muvundja, 2020;Naharuddin et al, 2020]. In order to obtain the P factor, this study conducted field observations and interviews with farmers utilizing the Dolago watershed.…”

Soil loss assessment in watersheds is useful in developing plans for the protection and conservation of soil and water in a sustainable manner. This study aimed to determine erosion hazard classification and erosion hazard map using Revised Universal Soil Loss Equation (RUSLE) as the basis of a soil and water conservation planning program. The RUSLE model was used to assess soil loss and guide the soil conservation efforts. Annual rainfall data, digital elevation model (DEM), land use map were used to generate the RUSLE parameters, namely rainfallrunoff erosivity factor (R), soil erodibility factor (K), slope length and steepness factor (LS), cover-management factor (C), and support practices factor (P). Erosion hazard is classified into five classes, namely very low, low, medium, high, and very high. On the basis of the results, at the Dolago watershed, very high erosion hazard was found in dryland of 577.95 t/ha/yr. Meanwhile, very low erosion hazard was found in the rice field of 2.22 t/ha/yr. The results help in planning and implementing soil and water conservation, both vegetatively and mechanically, to minimize the damage to watershed ecosystems. Validation and testing of the RUSLE model should be carried out in future studies because this is a strategic step to develop modeling of sediment yields effectively in an effort to mitigate major land damage in watersheds.
