Prior state
Agricultural land had expanded for the whole of recorded history apart from local reversals, with abandonment in Europe, Japan, and Korea offset by expansion in South America, Central Africa, and Southeast Asia. Conservation meant protecting land from agriculture.
Material change
Global cropland and pasture area reaches its maximum and begins to fall. Population plateau, continued yield growth, and the substitution of fermented and cultured protein ingredients for a share of commodity dairy and feed demand reduce total land requirement. The political question inverts, from how to stop agricultural expansion to who owns and decides the use of released land, with rewilding claims, solar and biomass developers, carbon-removal financiers, and returning pastoralists in direct competition.
Why now
The peak occurs when demand growth finally falls below yield growth, and both curves were set in preceding decades: the population plateau inferred at the interval's start, the maturity of protein substitutes whose cost curves crossed commodity parity in the 2040s and 2050s, and the completion of the largest tranche of Cerrado and Southeast Asian conversion before the interval. The contest over released land becomes acute in this decade specifically because carbon-removal obligations and land-based offset accounting from mid-century policy reach their compliance periods within it.
Mechanism and resistance
Release happens through the exit of marginal producers under higher capital costs and through consolidation. Resistance comes from farm constituencies defending production subsidies, from states treating agricultural land as a security asset, from smallholders with insecure tenure who are easiest to displace once land acquires a carbon or energy value, and from the ecological reality that abandoned land often returns as degraded scrub rather than as habitat.
Consequences
Biodiversity outcomes depend on who wins these contests, and the winners are typically well-capitalised. Sahelian and Deccan pastoral and communal systems that gain recognised title convert release into livelihoods; those without title lose access to land they had used for generations. Food prices decouple somewhat from land constraint and recouple to water and heat constraints, which is the domain of D09 and D21.
End state
The world enters 2072 with global agricultural area declining, a large and growing category of land whose designated purpose is carbon, habitat, or energy rather than food, and a new class of land-tenure conflict centred on formerly marginal ground.
Observable test
Global cropland and permanent pasture area in agricultural statistics and remote-sensing land-cover series shows a peak followed by multi-year decline, and the area under formal carbon, habitat, or renewable-energy designation on formerly farmed land grows into a statistically significant land-use category.
Disconfirming sign
Cropland and pasture area continues its historical expansion through the decade, driven by biofuel demand, feed demand, or yield stagnation under heat stress.
