This paper presents a dynamic model of land resource degradation and shifting rice cultivation in West Africa based upon Boserup and Dvorak. The model indicates the ex ante impact of research strategies to maximize the economic benefits of host plant resistance and land resource management and thereby stabilize yield decline and reduce land degradation.

This investigation was conducted for both constituting an urban land use planning and criticizing the appropriateness of the uses with respect to ecology by taking into consideration the ecological factors in the centre and the periphery of Çanakkale city. A method based on "Maximum Values Map Approximation Method" was used in this present study. A suggested land use map of the study area was constructed for these usage types according to the arrangements of their priorities by the experts.

Riparian buffers, the strips of vegetation along banks of rivers and streams, have been proposed as a key instrument to protect water quality in the United States. Riparian buffers impose a restriction on the use of private property limiting harvest and development, but buffers can also provide for aesthetic and recreational benefits that may accrue to property owners. With data from the Neuse River Basin in North Carolina, this study attempts to provide empirical evidence on the effect of a mandatory buffer rule on the value of riparian properties.

This article develops a theoretical model to analyze the spatial targeting of incentives for the restoration of forested landscapes when wildlife habitat can be enhanced by reducing fragmentation. The key theoretical result is that the marginal net benefits of increasing forest can be convex, in which case corner solutions--converting either none or all of the agricultural land in a section to forest--may be optimal. Corner solutions are directly linked to the spatial process determining habitat benefits and the regulator's incomplete information regarding landowner opportunity costs.

We conduct a national-scale study of the determinants of agricultural land values to better understand how current farmland prices are influenced by the potential for future land development. The theoretical basis for the empirical analysis is a spatial city model with stochastic returns to future land development.

The current support policy is increasing gaps in land management intensity among different regions of the country. The support policy for agricultural and rural development does not deal with solutions for land abandonment or environmental objectives, because the abandonment is becoming a hidden, environmental policy and rural development process, which is more expensive for society. Some alternative approaches and principles for designing a new agricultural land policy for Latvia could decrease the policy costs and make land management more targeted and acceptable for society.

The basic agricultural structure in Poland consists of small and medium family-owned farmsteads. Public funds grant their support primarily to farmers capable of competing efficiently within the EU market. In most cases, that means farmsteads covering a larger area. It is the real property market that regulates the agrarian structure. Therefore, the goal of this paper is to present the situation on the farmland market in respect to Poland's membership in the European Union.

In the research was submitted agricultural land market in Poland, in the political system transformation conditions, with consideration it function, stimulating the structural change of farming including territorial structure. There were characterized changes occurring in polish country with indication of the following processes: growing strength of agricultural land market, increasing role of agricultural lands' lease and also progressive process of land concentration and changing ownership relations.

The Porter Hypothesis relates the effects of environmental regulation on (a) technological innovation and (b) economic performance. Specifically, it asserts that innovation offsets can occur. These are a type of technological change that will "partially or more than fully offset the costs of complying with environmental regulation" (Porter and van der Linde, 1995, p. 98). The hypothesis has been highly debated, in part, because nomenclature has been careless. Also, the role of property rights in defining innovation offsets has been neglected.

The purpose of the study was to find out the factors affecting farmland prices in Finland. A hedonic pricing model that takes into account the presence of spatial dependence was applied for a very large sales price data (6 281 observations). The results confirmed the importance of land quality and the structural change as determinants of land price. In addition, off-farm job possibilities seemed to have a significant role in determining land prices.
