Prior state
Cropland extent has been roughly stable or slowly declining for some time entering the century, with intensification offsetting population decline and with substantial land still devoted to feed and to low-yield subsistence cultivation. Rural populations are aged and shrinking but agriculture remains a major employer in parts of Africa and South Asia.
Material change
The direction of the ten-thousand-year expansion of cultivated land reverses decisively rather than marginally. Feed-crop area collapses as fermentation-derived and cultured protein displaces the least efficient animal production, enclosed cultivation absorbs high-value horticulture, and the population being fed keeps falling. Land leaves agriculture faster than any policy intends. With it goes the peasantry: the smallholder cultivating household, which has been the modal human economic unit for most of recorded history, ceases to exist as a significant social category anywhere.
Why now
Three independent pressures converge inside the century rather than at any particular year within it. Population decline compounds to the point where aggregate calorie demand is unmistakably falling. The generational succession problem resolves itself by attrition — the last cohorts willing to inherit marginal holdings do not appear, and land passes to consolidators or to nobody. And enclosed, energy-intensive production becomes cheaper than field production for an expanding list of crops once electricity is nearly free at the margin in the relevant latitudes.
Mechanism and resistance
Consolidation, abandonment, and then deliberate release, in that order. Resistance is powerful and partially successful: agricultural constituencies retain outsized constitutional weight in many inherited political systems and defend subsidy regimes for decades; cultural and religious attachment to cultivation, particularly around rice in monsoon Asia and around pastoral systems in the Sahel and Central Asia, sustains production well past economic rationality; and a genuine strategic argument about food autonomy keeps several regions cultivating deliberately at a loss. The result is that release is slower and patchier than the economics predict, and that the surviving agricultural landscape is heavily shaped by policy rather than by soil.
Consequences
The released land does not become wilderness in any prior sense. It becomes novel ecosystems assembled from whatever survived the preceding centuries of disturbance, shaped by deliberate species introduction and by an inherited soil legacy of compaction, nutrient loading, and residual contamination. Soil carbon and soil biota recover substantially over decades, which contributes materially to atmospheric drawdown. Rural political power, already declining, collapses. Food security improves in aggregate and becomes more dependent on energy systems and less on weather, which is a genuine change in the character of famine risk rather than its elimination. Pastoral and smallholder societies whose identity was inseparable from cultivation experience the change as cultural extinction, and their political and religious responses shape the century's identity conflicts.
End state
Cultivated area is substantially below its historical maximum and still falling. Agriculture is a capital-intensive, energy-intensive sector employing a negligible share of humanity. Large contiguous areas of former cropland on every inhabited continent are under ecological management rather than production, and the smallholder household has passed out of existence as a modal form.
Observable test
A future observer would find total cultivated area at its lowest extent since the early agricultural expansion, agricultural employment negligible in every region including sub-Saharan Africa and South Asia, and formal ecological management designations covering large areas of formerly cultivated land.
Disconfirming sign
Cultivated area stabilizes or expands, whether because dietary substitution fails on cost or acceptability grounds or because food-autonomy policy universalizes protected domestic production.
