Increases in populations have created an increasing demand for food crops while increases in demand for biofuels have created an increase in demand for fuel crops. What has not increased is the amount of croplands and their productivity. These and many other factors such as decreasing water resources in a changing climate have created a crisis like

The 1979 publication Where Have All the Farmlands Gone? by the National Agricultural Lands Study painted a bleak future for American farmlands. Threatened by encroaching construction and soil erosion, these lands were seen as endangered--and as the direct prelude to a nationwide shortage of both food and fiber. The NALS report, to which eleven federal agencies contributed, argued that landuse planning and control must be employed to protect valuable farmland from "urban sprawl." First published in 1984, this collection of essays by a distinguished group of economists, including Theodore W. Schultz, Julian L. Simon, and Pierre Crosson, takes issue with the belief that croplands need governmental protection. Rather, the collection as a whole supports two theses: 1) shrinking farm acreage is not a serious problem, and 2) individual choices by landowners in a free market setting result in betterorganized land use than would governmental landuse planning and regulation.

This book not only highlights the risks associated with large-scale investment, but also advises on how governments can create an environment to attract investment that contributes to broad-based growth and poverty reduction in cases where land acquisition by large investors makes sense from a social, economic, and environmental perspective.

Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Agricultural GDP in Ethiopia grew at an average 7.3 percent per year between 2001/02 and 2012/13. Most of this dynamism occurred in the highlands, where high population density and land scarcity begs the question of how future agricultural output can be maintained to sustain the previous decade’s momentum. This paper uses a spatial regression approach to calculate the maximum crop area potential of each kebele in Ethiopia. We find that although the highlands have a greater potential for cropped area, there is little room to expand. A substantial share of the highlands has limited economic potential to expand the land base devoted to agriculture. In fact, many areas may be reaching an environmental threshold that will require the local agricultural land area to contract to maintain the agricultural productivity outcomes realized in previous years.
