Five assessments covering less-developed countries have identified a ‘land balance’, available for future cultivation, using the approach of inventory and difference: assessment of the area cultivable, and subtraction of the area presently cultivated. All arrive at a balance of 1600–1900 Mha, about twice the present cultivated area. The supposed existence of this spare land is widely quoted in forecasts of capacity to meet the food requirements for future population increase. It is argued here… 
Assessment of global land availability: land supply for agriculture
We developed a new assessment method of the land supply for agriculture, on a grid scale basis and per region, which takes into account both biophysical, institutional and socio-economic parameters
Land use and agricultural productivity in Ghana
Uncertainties persist in sub-Saharan Africa regarding both the availability of land which could be put under cultivation as well as the potential for an important improvement in yields. In order to
Estimating the world's potentially available cropland using a bottom-up approach
A review of global potentially available cropland estimates and their consequences for model‐based assessments
TLDR
A high, a medium, and a low estimate of cropland availability are constructed that are representative of the range of estimates in the reviewed studies and applied in a land-change model to illustrate the consequences on croplands expansion and intensification as well as deforestation.

Extending global irrigation maps – going beyond statistics
Agriculture is the largest global consumer of water. Irrigated areas contribute to 40 % of the agricultural production. Information on their spatial distribution is highly relevant for regional water
A global approach to estimate irrigated areas – a comparison between different data and statistics
Abstract. Agriculture is the largest global consumer of water. Irrigated areas constitute 40 % of the total area used for agricultural production (FAO, 2014a) Information on their spatial
Sparing land for nature: exploring the potential impact of changes in agricultural yield on the area needed for crop production
How can rapidly growing food demands be met with least adverse impact on nature? Two very different sorts of suggestions predominate in the literature: wildlife‐friendly farming, whereby on‐farm
An Exploration of Human-Environment Interactions that Shape the Earth's Surface
The world’s population is growing and demand for food, feed, fiber, and fuel is increasing, placing greater demand on land and its resources for crop production. We review previously published
