His thesis is that, over the last 20 years or so, agricultural production and marketing systems, particularly in developing countries, have been made more efficient, with fewer agricultural marketing boards, more production driven by the market and less by government subsidy, lower or no levels of government-owned grain reserves, etc. But, while the systems are more efficient, they are more fragile. He writes:
"The old emphasis on food security was undoubtedly costly, and often wasteful. But the redundancies it created also had tremendous value when things went wrong. And one sure thing about a system as complex as agriculture is that things will go wrong, often with devastating consequences."It's an interesting contrast with Prof. Pollan's thesis which says that government subsidies have distorted production, and made corn cheap.
