Competition for land

Competition for land

A key challenge for humanity is how a future global population of 9 billion can all be fed healthily and sustainably. Here, we review how competition for land is influenced by other drivers and pressures, examine land-use change over the past 20 years and consider future changes over the next 40 years. Competition for land, in itself, is not a driver affecting food and farming in the future, bu...

Competition for Land and Economies of Density

Development projects often involve assembly land from a variety of different owners to form a large continguous plot. Such aggregation makes it possible to operate the project on a large scale, which can confer efficiency benefits. However, the aggregation process can simultaneously raise issues. On the one hand, small landowners may try hold-out strategies, with the aim of extracting the full ...

The Nexus Land-Use model, an approach articulating biophysical potentials and economic dynamics to model competition for land-use

Interactions between food demand, biomass energy and forest preservation are driving both food prices and land-use changes. This study presents a new model called Nexus Land-Use which describes these interactions through a representation of agricultural intensification. The model combine biophysics and economics to calculate crop yields, food prices, and resulting pasture and cropland areas wit...

Land inheritance establishes sibling competition for marriage and reproduction in rural Ethiopia.

Intergenerational transfer of wealth has been proposed as playing a pivotal role in the evolution of human sibling relationships. Sibling rivalry is assumed to be more marked when offspring compete for limited heritable resources, which are crucial for reproductive success (e.g., land and livestock); whereas in the absence of heritable wealth, related siblings may cooperate. To date, comparativ...
