In Uganda, natural forests have
undergone both spatial and temporal changes from various drivers, which need to
be controlled in order to determine the effect on habitats of such changes and
to avoid the associated risks of reducing the benefits of ecosystem services.
Due to dual ownership, ground research can be complicated, although remote
sensing techniques and GIS application allow rapid multi-temporal detection of
changes in forest cover and provide a cost-effective alternative for
inaccessible areas and their use to detect changes in ecosystem service. The
overall objective of this study was to use satellite measurements to study
forest change and relate it to reducing the value of ecosystem services (fresh
water) in the study area using a representative Landsat scene sample, Using
soil moisture content time series satellite data, the effect of forest cover
loss on drought prevalence is also assessed. In addition to evaluating the
economic vulnerability of households to drought in rural Uganda 's central
districts, In this paper, together with post-classification comparison, an
integrated approach of remotely derived indices was used to detect forest cover
and ecosystem service transition. In addition , the analysis used soil moisture
content data from the satellite time series to determine drought prevalence and
household susceptibility to drought shocks. Our new contribution is the ability
to detect a decrease in private and central reserve forest cover on a
multi-temporal scale along with ecosystem coverage. Reduction of profit in the
20-year period (1986-2005) using remotely derived indices. Analysis of change
detection showed that in five sub-counties of Mpigi, forest cover decreased
significantly than in Butambala by 5.99 percent, disturbed forest was 3
percent, farm land increased by 44 percent, grassland decreased by 62.5 percent
and light vegetation increased by 63.6 percent. The two areas most impacted
have suffered decreases in fresh water. The two SPI and SWDI drought indices
confirmed the presence of drought shocks that have triggered household
vulnerability to food insecurity and welfare instability. Resource managers ,
especially natural forests, must also include private resource owners in the
conservation effort in order to ensure a sustainable supply of ecosystem
service benefits and preservation of standard welfare.
