Abstract |
: |
This study investigates environmental degradation and its impact on ecotourism in Jazan,
KSA, using remote sensing and GIS. The study aimed to employ remote sensing and GIS to
study the state of the vegetation threatened by desertification in the Jazan region. Two
Landsat satellite images (ETM) captured in May 1987 and May 2002 were acquired for the
purpose of this study and were processed and analyzed using ERDAS Imagine V. 8.5. The
final output maps have been produced using Arc GIS V.9.2. The results of the study indicated
that the vegetation of Jazan was exposed to environmental degradation between 1987 and
2002, especially in the eastern highlands and mountain slopes. The area lost approximately
46 % of its total vegetation cover between 1987 and 2002, an average annual loss of 3 %.
This information clearly reveals the deterioration and decline of the vegetation in 2002, a
change that will inevitably contribute to the emergence of desertification and drought
(Ignacio et al. 2010). In addition, the demographic growth and steady increase in population
produce their own effects on the productivity of agricultural land and cause soil erosion and
drying due to decreases in organic elements. All of these factors result in desertification and
its associated negative effects on ecotourism in the Jazan region. In addition, this continuous
loss of green spaces causes a decrease in the individual shares of green areas. Several
strategies are recommended to deal with this problem. |
