For years, the lands in Cameron Highland have been opened and leveled for agricultural farming and intensive crop production. The overall agricultural coverage is relatively small and is mostly done on steep slopes. The high usage of fertilizer and pesticides by local farmers, accompanied by the increase in the frequency of major storm events had given rise to high levels of soil erosion and environmental pollution. In this study, a guideline has been stablished to be used by the local authorities and farmers to conserve soil, protect the natural waterways and the surrounding environments from man-made pollutions.

The proceedings book of the Global Symposium on Soil Erosion (GSER19) contains all papers presented both orally and in poster format during the symposium (15-17 May 2019, FAO HQ). The papers presented have provided sufficient scientific evidence to show that soil erosion is a global threat to food production systems, available land for future demand, rural livelihoods, human health and biodiversity, and that coordinated effective action needs to be fostered and accelerated to address this issue. Studies presented provided scientific evidence that soil erosion is accelerated by anthropogenic action. In the current context of population increase and climate change, urgent action is needed from governments to support farmers and land-users in the transition to sustainable production systems, and crucial action is needed at global level to raise awareness of the importance of healthy and productive soils, to ensure a sustainable future and the achievement of many of the SDGs targeting hunger, water quality, and life on land, amongst others.
Focusing on reservoir sedimentation management and control, this work defines the nature and severity of sedimentation, reviews relevant physical processes, describes techniques used to combat sedimentation, and presents detailed case studies.
