The green revolution came along with crops which could resist pests,
take advantage of fertilisers and irrigation and were suited to big
monocultures.
We are losing access to water and thence irrigation because of global
warming.
Industrial agriculture won't work when oil and gas run out as we will
lose fuel, fertiliser and pesticides.
Insects are evolving which by passour defenses. See this weeks "New
Scientist" where Nobel Laureate, Norman Borlaug and the inventor of
the Green Revolution is quoted saying "this thing has immense
potential for social and human destruction"[1]. Wheat blight is back.
In almost all areas of the world soil is being lost and degraded.
We are going to lose the green revolution. We are already pushing at
the limits of photosynthetic productivity [2] and the other inputs
are being eroded.
