Just a random assignment i did. Thought i post it out here.
I forgot which subject this was. Well, nevermind. I’ll update after this.
Project Activities
|
Potential Impacts
|
Proposed Mitigating Measures
|
Pre-Construction
l Clearing of land
(land reclamation)
|
1. Surface water run-off into nearby river, caused water to become shallow.
2. Blockage of river caused potential flash-flood
|
a) Proper drainage system and ponds to trap sediment
b) Construct agricultural area in a safe distance from nearby rivers (buffer zone)
|
Construction/Operational
l Fertilisers (phosphate, ammonia, nitrate)
|
1. Eutrophication (excessive nutrient into nearby river)
2. Increase temperature and capacity to dissolve oxygen decreased.
|
a) Avoid using fertilizers when there is a predicted heavy rainfall events.
|
l Pesticides/Herbicides (atrazine-used to control weeds growth)
|
1. Pesticides can enter groundwater bodies, and contaminate it.
|
a) Use ponds to trap sediment from nitrate
b) Use non-chemical alternatives (manure)
|
l Harvesting activities
|
1. Surface run-off, top soil to wash away and settle at the bottom of river (shallow river, water flow with mud)
|
a) Must well-planned the activity to avoid the clearance land being left bare in a long term period
|
Post- Construction
l Use of plastic mulch in agriculture to cover soil
|
1. Increased amount of waste from the plastic much into the river
|
a) Install waste bin or reuse the plastic mulch.
