SUSTAINABLE AGRICULTURE

TOWARDS DEVELOPMENT

BYMR. ALLAH DAD

TRENDS IN SUSTAINABLE AGRICULTURE

The onset of the industrial age brought about various trends that have led us toour present state.

The quick rise in population. More people to feed.

The greater need for production. Farms required to produce more.

The increase in urbanism. Less farms to do more work.

Wide-spread ecological impacts. Faith in technological, political

and economic fixes.Today, “less developed countries” are following a similar trend.

Many farmers in these countries choose to grow cash crops rather than subsistence crops.

Regions reliant upon cash crops tend to develop adverse, long term environmental problems.

A. Crop rotation keeps the soil healthy. Mixed farms allows the uses of livestock manure. D. Small changes in practices can help, rather than harm, the environment. E. livestock control weeds without chemicals or mowing. F. Science can determine the right amount of fertilizers and pesticides. G. Farming removes nutrients and fertilizers or manures replace them. H. Farming multiple crops allows farmers to reduce their financial risks by

having multiple products to sell.
