The Conservation Reserve Program (CRP), first enacted in 1985, seeks to achieve both conservation and agricultural supply control objectives through voluntary, long-term (10 year contracts) retirement of cropland. By fall 2000, the program had enrolled about 31.4 million acres nationwide, and North Dakota ranked third among the states, with 3.2 million contracted acres, or 11 percent of the state's total cropland.

The aim of this research was to determine physical land evaluation of hazelnut areas of Ordu-Unye and its vicinity. The study area, is located between west of Ordu and south of Samsun provinces, at coordinates 4542500-4537500 km N and 342500-347500 km E (UTM), covers approximately 31.5 km2. The study area consists of various topographic features such as, hilly and rolling physiographic units commonly. Elevation varies from 200 m to 600 m above sea level. Average annual precipitation and temperature are 1162.4 mm and 14.2ºC, respectively.

An analysis of Conservation Reserve Program contracts obtained during the 1986 sign-up periods indicates commodity program participants enrolled more acreage at higher costs than farmers not participating in other commodity programs. Significant differences also occurred between the various commodity program crops, reflecting the difference in benefits available for these crops.

The security district of Hatay, Kilis, Gaziantep, Sanliurfa, Mardin and Sirnak province located along southern boundary lies between Turkey and Syria that comprised wide areas. It is considered to evaluate of cleaned mined land with a 300-400 m width and 510 m length. It was estimated that these lands were very productive and that can be used for organic or other types of agriculture .If these lands are cleaned and opened to agriculture, that can create jop opportunities to many families in agriculture.

Farmland values, cash rental rates, and federal farm program payments steadily increased in the Northern Plains from 1991 - 2001. Econometric models are used to examine the impacts of Federal farm payments on cropland values and rental rates, statewide and regional,in South Dakota during this time period.

Objectives of this research were to determine the socio-economic condition, opinion level and factors related to opinions on the reform land use pattern of the villagers of Ruamthai Demonstration Cooperative Village, Kui Buri District, Prachuap Khiri Khan province. A designed questionnaire was used as a tool for gathering the data by interviewing 260 respondents from Ruam Thai village (Mue 7), Pu Bon village (Mue 8) and Yan Sue village (Mue 9).

In the conditions of the Republic of Belarus there was developed an information model for the provision of use and protection of arable lands taking into consideration the main sources and factors of anthropogenic influence on land resources. The model of information supply of the usage and protection of agricultural lands took into account data about their initial (base) condition and data about current changes, as well as analytical and archive data. It reflected ecological-economic side of management of land resources.

More than 124 governmental entities concerned about suburban sprawl and farmland loss have implemented farmland preservation programs preserving 1.67 million acres at a cost of $3.723 billion. We ask how effective are these programs in slowing the rate of farmland loss. Using a unique 50-year 269 county panel data set on preservation programs and farmland loss for six Mid-Atlantic States, we employ the propensity score matching method to find strong empirical evidence that these programs have had a statistically significant effect on the rate of farmland loss.

Using a unique spatial database, a hedonic model is developed to estimate the value to nearby residents of open space purchased through agricultural preservation programs in three Maryland counties. After correcting for endogeneity and spatial autocorrelation, the estimated coefficients are used to calculate the potential changes in housing values for a given change in neighborhood open space following an agricultural easement purchase.

Land use change in developing countries is of great interest to policymakers and researchers from many backgrounds. Concerns about consequences of deforestation for global climate change and biodiversity have received the most publicity, but loss of wetlands, declining land productivity, and watershed management are also problems facing developing countries. In developing countries, analysis is especially constrained by lack of data.
