1. Environmental Pollution in
Agriculture:
Factors & Strategies for Mitigation

2. Pollution
The presence in or introduction
into the environment of a
substance which has harmful
or poisonous effect .
Example: CO2, CO, SO2 etc.

3. Environmental Pollution in Agriculture:

the operation of agriculture
[ 58% of water pollution is occurred from
agriculture (FAO) ]

4. Reasons of Pollution
 Pesticides
 Fertilizers
 The exhaust gases from machineries

into some groups:
i) Effects of Water pollution:
 Kills organisms
 Disrupts natural food chains
 Can cause sickness or death
 Reduces of available safe
drinking water
 Reducing fish production

6. Continued…………
ii) Effects of Soil Pollution:
 Reduces soil fertility
 Reduces Nitrogen fixation
 Larger loss of Nutrients
 Reducing crop yield

7. Continued…………
Effects of Air pollution:
 Reducing oxygen level
 Causes headache & Nausea
 Global warming
 Wild life hamper

8. Some statistics:
 In recent past, five farmers died in kochua upazilla during
spreading pesticides.
 In Tanor, Rajshahi, a farmer died from pesticides side effect

9. Mitigation
 Use of fertilizer & pesticides in low amount
 Use of green manure in large amount
 Drainage water management
 Use of solar energy
 Conservation tillage
 Solid waste management
