Impact assessment is the process of identifying the future consequences of a current or proposed action. It is used to ensure that projects, programmes and policies are economically viable, socially equitable and environmentally sustainable.

MANGROVES
PUNJAB URIAL
INDUS DOLPHIN
PALLA FISH

30. Mangroves
• Mangrove forest cover an area of almost
0.32 MA
• Spreading from Karachi in the west to
Rann of Kutch in the east
• 95% of the population now consist of a salt
tolerant variety

31. • Extent of the active delta area is about
294,000 acres.
• Out of this, the mangroves cover only
7,400 acres or 2.5% of the area

32. Cause of mangrove decline is actually tidal
inundation, not fresh water decline.
In fact, it is seen that after building a dam,
mangroves usually flourish rather than
declining.

33. After Project Mitigation
Salt tolerant and controlled fresh water
in-taking plants will be installed.

34. Fisheries
After formation of dams and barrages,
fish population usually increases.
Example : Kotri Barrage
Fish will remain unaffected.

35. But if, problem arises
• Fresh water reservoir(s) for fish farming
will be provided to local people.
• And subsidies will be given to local people
for their loss

36. Indus River Dophin
Population: 1,100
Status: Endangered
Cause of decline: Diversion

37. But, now
• P.minor has adapted to muddy and silted
water
• Now the main problem is not ‘diversion’
but ‘illegal catching’

38. What Kalabagh Dam will
Provide
• Proper Monitoring
• Reducing their catching
• Provision of funds to organizations like
WWF

39. Effects on Crops

40. In the riverain area downstream to Kotri
Barrage, groundwater is predominantly
saline or brackish and as such unsuitable
for either irrigation water supply.

41. Solution
After Kalabagh, winter supply in the river
would improve thus assuring more suitable
water for irrigation.

42. Punjab Urial
• Status: Threatened
• Indus is located
west to their habitat
• Population: 2,157

43. Effects Of Kalabagh
• Cause of decline: Illegal hunting
• Water shortage/ Water requirements were
never the causes of decline
• Kalabagh will have no effect on the
vulnerable urial specie
