3. Introduction
● Though farming is an essential part in this earth but it
causes a great impacts on biological diversity
● Agriculture is the major cause of being deforestation and
replaced 70% of grassland
● Various conservationists are working to alleviate the
consequences of farming for biodiversity and ecosystem
● Same time conservationists need to know by maintaining
preservation of land how to fulfil the increasing demand

• Demand will rise by
70% worldwide between
2005 and 2050
• Demand for food
calories & protein will
increase by 100-110%
• Population growth
• Rapidly rising per capita
demand for non food
crops
• Changing food habit
• Dietary changes
• Far more land, nutrients
and water needed
• More nitrous oxide and
methane emitted
Future Demand Main Drivers Impacts
Increasing demand of food

Wheat
Rapeseed
Beans
Soybeans
Barley
Millet
Rice
Maize
Cotton
Crops that cover greatest land area
Those items of production account for two-thirds of global cropland

8. Assessing which farming methods have greatest potential
Source: Balmford et al., 2012
Different farming techniques
• Lowering externalities
• Enhancing nutrients &
efficiency
• Increase resistance to
pests
• Boosting drought
tolerance
Genetic
Modification (GM)
• Fine-tuning fertilizer
• Reducing inputs
• Increase resource
efficiency
• Drip irrigation
• Reduce pollution inputs
Precision
Agriculture
• Yields increased by using
companion crops
• Known as vuta sukuma
• system increases maize
yields from less than 1-
3.5 t/ha/yr
Push-Pull

10. Conclusion
Source: Balmford et al., 2012
● Due to increasing food demand and changing of food habit nature will change dramatically within
next 50 years
● Conservationists may focus on key harmful impacts on farming
● Conservationists and farmers should work together to make a proper solution
