IntroductionThe study area is located at Lojing, Kelantan.
The average monthly temperature is range between 12 – 26 0C
The annual rainfall is range between 1800 – 2900 mm
This area is suitable to plant temperate crop such as tomato, chilies, capsicum, and etc.

These problem happened due to - Carry out land work without
approval (kebenaran merancang, KM)
- Carried out the land work not conforming to the approval plan
- No EIA - No ESCP - Slope failure
- Encroaching forest reserves

Soil LossBased on the soil loss assessment showed an increase in soil loss from
15,000 m3/year in 2008 to 63,700 m3/year in year 2016, which
corresponds to a 430% increase.
The massive landuse change has contributed directly on the increased of turbidity and total suspended sediment (TSS) in Belatop River.
TSS value at Sg.Belatop during the last visit (July 2019) is about 1230 mg/l compared with pristine condition which less than 50 mg/l

How to resolve this issue - ESCP Implemented Project

Preparation of Development Plan
1) Plan the development to fit the site of abandoned farm plotsonly
2) ESC planning were integrated into site and development3) Runoff from the site were controlled4) Disturbed areas were promptly stabilized5) On site sediment retentions were maximized6) ESC practices were regularly monitored and maintained

The project is within abandoned farm land that lies on a flat terrain hill plateau. (Malaysia Agrifood Corperation)
