Is there enough existing agricultural land to feed and fuel the world?

Food insecurity, deforestation, climate change, and energy insecurity all interact and have led to questions about the sufficiency of agricultural land. There is sharp debate; Cornucopians suggest land limitation is a myth and there is plenty of land for food and bioenergy, while Malthusians posit that supplying land for food is problematic, let alone emerging bioenergy land demand. To better understand, we examined the suitability of pasture for corn or sorghum using two separate geographically distributed models: ERWATR and CROSUR. We find there is sufficient supply under best case scenarios, but insufficient supply under less than ideal conditions.

Temporal Data from a Digital Comparison of Historical Maps of Barbados

During the colonial phase of Barbados’ sugar industry, a number of maps were made of the island conveying a remarkable amount of cultural and economic information. Differing cartographic choices and varying levels of accuracy provide an intriguing challenge in comparing these maps. Point locations of sugar plantations were displayed, but with a span of sixty-seven years between maps, plantations often arose, changed hands, or disappeared. Additionally, only a percentage of all plantations were shown, and each cartographer had different motives for which to include. Considering these maps together using modern GIS techniques reveals cartographic biases in what is shown.
