DUE TO WASTE
WATER.UNFIT OF
AGRICULTURAL LAND DUE
TO CONSTRUCTION OF
DAMS , PROJECTS ... IN
NEAR BY PLACES.
INSUSTRIAL

PROCESS BY WHICH NON-
RENEWABLE SUBSTANCES
AND VALUABLE MINERALS
ARE
EXRACTED FROM EARTH.IT

15. •LAND DEGRADATION AND DROUGHT IN INDIA:
It is important to protect the land from deforestation,
fragmentation, degradation and drought. About 69% of
India's total geographical area is under dry lands
.These areas incidentally are highly populated which
makes the people impacts livelihoods directly .
An estimated 32 percent of India’s total land area is
affected by land degradation.
16. •LAND DEGRADATION IN
EGYPT:
In the Nile valley and reclaimed desert fringes, land
degradation is caused by water logging, alkalinity of
soils And soil pollution by agrochemicals and
chemicals from industry.
Lands in the eastern desert are degraded due to
water and wind degradation .
Land degradation in western desert are over
exploitation of soil groundwater resources .
Land degradation in northern coastal belts are
degraded due to overgrazing , wind ,conversion of
rangelands in rain fed croplands.
