The Green Revolution
Positive effects, in the long run
While there may be some adverse effects regarding health or the environment, this will be fixed by the improved infrastructure, but the issue of simple food must be resolved first.
This is not even to mention the fact that, with yields increasing by 30% or more, less people in the country are left without foodstuff. Feeding people is more beneficial than preserving the environment at some point, and spurs development far more.
So what about later?
Can't think on an empty stomach
Once this occurs, the country will be much stronger. WIth this new power, it is far easier to tackle problems regarding health or the environment, and now with food as opposed to if the green revolution did not take place.
India: an example
Wheat yield by hectare increased 30%, and in 1778 they exported 131 million tons of wheat.
Economic benefits included other countries being impressed by the effects of the green revolution, making india able to export workers and knowledge to them. The green revolution aided paying off national debts.
Infrastructure is increased as a side effect of the green revolution. To aide water needs, for example, dams were built to allow enough water for double cropping. These dams also provide hydroelectric power for the surrounding region and provide water.
