Quantitative analysis of the impact of deforestation on the ecosystem services in Kamfinsa sub-catchment of Kitwe

The objective of the study was to provide a holistic evaluation of the impacts of deforestation on
ecosystem services in Kamfinsa sub-catchment of Kitwe in Zambia. Loss of forest biomass,
biodiversity, and soil erosion were key proxy variables for loss of ecosystem services.
Geographical Information System (GIS) and Remote sensing techniques were used to assess the
impacts on the ecosystem. The results showed that deforestation reached 576.3 hectares per year.
The forest loss corresponds to an emission of 43.73 ton of carbon per hectare from above and
below ground biomass valued at US$243.60 per hectare. According to a soil erosion risk
assessment, 1.59 ton of soil was lost per hectare per year, equivalent to US$ 57.20 loss per hectare.
The indigenous forest cover reduced from 13,430.5 ha (1990) to 2,904.7 ha (2010), with a
corresponding change in NDVI index for loss of forest vigor and biodiversity of 0.56 and 0.32,
respectively. The major forest loss occurred from indigenous forests. The study has shown that
deforestation in Kamfinsa sub-catchment area calls for the urgent promotion of an integrated and
comprehensive approach to addressing the drivers of deforestation to ensure continued supply of
ecosystem services.
