This paper provides a theoretical framework to analyse land quality and labour allocation decisions by poor rural households in the context of increased population densities in slash-and-burn (shifting cultivation) agro-ecosystems. A bio-economic optimal control model is presented and its results calibrated with data from two farming communities from Yucatan (Mexico). The ecological-economic model restates the validity of the neo-Malthusian 'Population Pressure Hypothesis' (PPH) as a major factor of land degradation.

Sustainability of agricultural land use is determined by economic and environmental characteristics of land resources. The method for land use assessing, which enables to determine the type of its environmental and economic status (EES), was developed. The method includes the calculation of performance indicators, drafting the scale and the determination of the cumulative EES for land.

The focus of this research is to check if urban crime is related to the social spatial urban structure and to identify the most unsafe territories in the city of Klaipeda from the point of view of crime and urban structure. Space syntax theory and method, as well as correlation analysis have been used for this purpose. The research results have revealed that all types of crimes depend on global integration and global depth: the more integrated and shallow the open public spaces are the more crime incidents in these spaces happen.

This paper aims to analyze the effects of paddy-field consolidation projects by using the stochastic model. Empirical results showed that the degree of effects, realized as a rise in rental rate and rental-area, vary in each region and that several factors influencing the project effects can be evaluated quantitatively.

Efficient land use plays an important role in the context of sustainable agricultural development. Assuming that it will be viable only in cases when individuals employed in agriculture can ensure themselves an income equivalent and not less than the average wage in the national economy. Certain sizes of agricultural area, which are different for every key agricultural sector, are required to achieve it.

This paper argues that state trust land management experience is potentially a source of valuable insights and examples for the U.S. Forest Service. The paper sketches historic and current trends in public resource administration to define what constitutes useful new ideas which might aid the agency in its present crisis.

The concept of land consolidation is new in Latvia. Its main tasks are to eliminate land fragmentation and to facilitate farms of optimal size. One of the most important preconditions of land consolidation is forming of optimal size farmland plots in property and use, and land fragmentation, which has a major impact on both the operating conditions and other rural development processes. Land fragmentation affects not only land management, but it also increases transport costs.

This study is carried out to determine land use changes by Geographic Information Systems and Remote sensing methods in Yenimahalle district of Ankara province. Changes in land use were identified between 2000-2005 and 2000-2010. For the study Landsat-5 image of year 2000, Ikonos image of year 2005, and SPOT image of year 2010 were used. 1:25000 scale topo maps and soil maps, and CORINE land use data were also used. GPS data collected from field were used for ground truth studies.
