Green Revolution

The Green Revolution is the term applied (originally by USAID administrator William Gaud in 1968) to a cluster of agricultural research and technology-transfer initiatives between approximately 1940 and 1980 that substantially increased crop yields across substantial portions of the developing world. The Revolution is at once one of the most consequential humanitarian achievements of the 20th century and one of its most consequential ecological-social setbacks. Both the achievements and the costs are substantial.

What it did

The principal accomplishments:

• Yield increases. Wheat yields in Mexico, India, and Pakistan increased by factors of 2–4× between approximately 1950 and 1980. Rice yields in the Philippines, Indonesia, and other tropical Asian countries increased comparably. Global cereal production approximately tripled between 1950 and 1990.
• Food security gains. India transformed from a food-aid recipient (the ship-to-mouth dependence of the early 1960s) to a grain exporter by the 1980s. Comparable transitions occurred in Mexico, Pakistan, the Philippines, and elsewhere.
• Famine averted. The mass starvation widely predicted in the 1960s — most famously by Paul Ehrlich’s The Population Bomb (1968), which forecast that the battle to feed all of humanity is over and predicted hundreds of millions of starvation deaths in the 1970s and 1980s — did not occur. The Green Revolution is substantially credited with this aversion.
• Borlaug’s Nobel. [[norman-borlaug|Norman Borlaug]] received the Nobel Peace Prize in 1970 for his work; he was the most prominent scientific figure associated with the Revolution.

How it did it

Several technical components, applied in coordinated fashion:

• Semi-dwarf varieties. Borlaug’s principal contribution was breeding wheat varieties with shortened stems (the semi-dwarf trait) that could support heavy seed-heads without lodging (falling over) under high-fertilizer conditions. Comparable rice varieties (especially IR8, the miracle rice developed at the International Rice Research Institute in the Philippines) followed. The semi-dwarf trait allowed the plants to use synthetic nitrogen for grain production rather than vegetative growth.
• Synthetic nitrogen fertilizer. [[haber-bosch-process|Haber-Bosch nitrogen]] applied at substantially higher rates than traditional agriculture used. Without intensive nitrogen, the new varieties did not outperform the old.
• Synthetic pesticides. Insecticides and fungicides protected the new high-density monocultures from pest outbreaks.
• Expanded irrigation. Tube wells (drawing on the post-WWII availability of cheap diesel pumps) opened substantial new agricultural areas, particularly in the Indian and Pakistani Punjab.
• Mechanization. Tractors, threshers, combines, and other mechanical equipment replaced animal and human labor; substantially shifted the economics of farming.
• Subsidized credit and input distribution. State agricultural-extension and development-bank infrastructure made the new inputs available to farmers, often substantially subsidized.

What it cost

The substantial criticisms:

• Petroleum dependence. The Green Revolution package depends on fossil fuels at multiple points — Haber-Bosch nitrogen (natural-gas feedstock), pesticide synthesis (petroleum feedstock), tractor fuel, irrigation pumping. The agricultural system the Revolution produced is one of the most petroleum-dependent agricultural systems in human history.
• Soil degradation. Intensive synthetic-nitrogen agriculture suppresses [[mycorrhizal-fungi|mycorrhizal]] symbiosis, depletes [[soil-organic-matter]], and produces progressive soil acidification and biological degradation. The high yields of the early decades have substantially declined in many Green Revolution areas as soils degrade.
• Aquifer depletion. The expanded irrigation that enabled the Revolution has substantially over-drawn aquifers across the Indus basin, the North China Plain, and other regions. See [[groundwater-depletion]] and [[aquifer]].
• Biodiversity loss. The replacement of traditional landrace varieties (each adapted to local conditions, with substantial [[genetic-diversity|genetic diversity]]) by a small number of high-yielding hybrids substantially reduced the agricultural [[genetic-diversity|genetic diversity]] that underlies long-term food security. Substantial seed-saving and seed-bank work (Vavilov, the Svalbard Global Seed Vault, the various national seed banks) has tried to preserve what was being lost.
• Smallholder displacement. The Revolution favored farmers with access to capital, credit, and irrigation infrastructure — typically larger farmers. Substantial smallholder displacement and rural-to-urban migration accompanied the Revolution in many regions.
• Health consequences of pesticide exposure. Substantial documented harm to agricultural workers and rural populations from intensive pesticide use, particularly the persistent organic pollutants used in early decades (DDT, lindane, others).
• Water-quality consequences. Fertilizer and pesticide runoff produced substantial water-quality degradation; the Indian Punjab, the Yangtze basin, and other [[green-revolution-aftermath|Green Revolution]] heartlands have substantial freshwater contamination.
• Distributional inequities. The Revolution increased food production substantially but did not solve hunger. As Amartya Sen demonstrated in his analysis of the 1943 Bengal famine and subsequent work, hunger is principally a distributional problem; the Revolution produced more food but also substantially restructured who could afford to eat.

What this means

A few continuing implications:

• The Revolution was both achievement and trap. The successes were real and substantial; the costs were also real and substantial; both must be acknowledged. [[0mn1one|The platform]]‘s posture: take seriously what the Revolution accomplished, take seriously what it cost, refuse to settle the question by collapsing one into the other.
• The food-system architecture remains. The contemporary global food system is substantially the Green Revolution architecture extended in scope. Hemispheric supply chains, monoculture commodity crops, petroleum-dependent inputs, consolidated farm operations — all are continuing legacies. Reform requires substantial restructuring, not incremental adjustment.
• The next agricultural transition. [[regenerative-agriculture|Regenerative agriculture]], agroecology, perennial-grain breeding (the work at [[the-land-institute|the Land Institute]]), agroforestry, and various other contemporary movements are substantially organized around the question of how to sustain and increase food production without continuing the Green Revolution’s costs. The work is ongoing.
• The Gates Foundation’s African [[green-revolution-aftermath|Green Revolution]]. From approximately 2006 onward, the Bill & Melinda Gates Foundation and partners have promoted a new [[green-revolution-aftermath|Green Revolution]] for Africa — substantial scale-up of synthetic-fertilizer agriculture, improved hybrid seeds, mechanization. The initiative is substantially controversial; criticism comes especially from African food-sovereignty movements (La Via Campesina, AFSA, others) which argue that repeating the Green Revolution model in Africa will repeat its costs.

What this gives the platform

The Green Revolution is one of the principal historical episodes [[0mn1one|the platform]]‘s regenerative-agriculture commitments are responding to. [[0mn1one|The platform]]‘s posture: take the Revolution’s gains seriously, take its costs seriously, and build forward toward agricultural systems that produce abundance without the petroleum-dependent industrial-monoculture architecture.
