The objectives of this Colorado study were to assess primary reasons ranchers choose to stay or sell the ranch, compare the motivations for ranching between a traditional agriculturally based county and a rapidly developing county, and assess whether factors such as length of tenure, fiscal dependency on ranching, and dependency on public lands play roles in decisions to sell. Personal interviews were conducted with 37 ranchers. While land use conversion occurs for a wide variety of reasons, lack of heirs and detrimental public policy were important reasons given for selling ranches.

A methodology is developed to relate urban growth studies to distributed hydrological modeling using an integrated approach of remote sensing and GIS. This linkage is possible because both studies share land-use and land-cover data. Landsat Thematic Mapper data are utilized to detect urban land-cover changes. GIS analyses are then conducted to examine the changing spatial patterns of urban growth. The integration of remote sensing and GIS is applied to automate the estimation of surface runoff based on the Soil Conservation Service model.

Met het in de Vijfde Nota Ruimtelijke Ordening voorgestelde beleid, worden de waardevolle landschappen in Nederland de komende 20 jaar vooralsnog onvoldoende beschermd tegen de oprukkende verstedelijking. Bij continuering van de huidige trends en zonder aanvullend beleid gaat in 2020 door verstedelijking ruim 20␟an de waardevolle landschappen verloren. Met name landschappen in de Noordvleugel van de Randstad en de provincie Utrecht staan onder druk. Het kabinet stelt in de Vijfde Nota wel doelen voor het behoud van landschap en introduceert onder meer het instrument 'groene contouren'.

In every region of the world, landscapes are being transformed. Rural people are migrating to urban centres in search of economic and social opportunities while city dwellers are becoming interested in producing their own food and moving outside the centres to be able to appreciate nature. These changes in lifestyles have implications for the food system and nutritional status of populations.

This paper draws on research on the enforcement of the Land Act of 1979 in Lesotho. It seeks to show that illegal settlements occur under the shadow of formal state rules, from which social actors borrow selectively and in opportunistic ways to acquire urban property rights. This is possible because of inconsistencies and contradictions in state rules and enforcement methods.

The trend is inescapable: more and more people in the developing world are living in the cities. By 2020, the number of people living in developing countries will grow from 4.9 billion to 6.8 billion. Ninety percent of this increase will be in rapidly expanding cities and towns. More than half the population of Africa and Asia will live in urban areas by 2020. More than three-quarters of Latin Americans already do.

Most agricultural output in the northeastern United States comes from counties that have experienced significant development. A mail survey, with 300 responses, was conducted in southeastern Pennsylvania to determine farmer adaptation to urbanization in this region. Despite development, traditional agriculture still predominates. Changes in land use were examined using multinomial logit models.
