Farmland values in the states of the Tenth Federal Reserve District rose about 5.5 percent over the year ended June 30, 1997 (McDaniel and Lamb). Indeed, over the past two years prices in many parts of the country have risen sharply. The jump in farmland values comes at a time of dynamic change in the farm sector. Last year, the federal government enacted sweeping farm legislation that both low...

Cele Oasis on the southern edge of Tarim Basin was used to investigate the impact of human activity on the soil environment of the oasis–desert ecotone during the oasis expansion process. Since farmland is extending into the oasis–desert ecotone during oasis expansion, reclaimed farmland and control plots within the ecotone were investigated. The variations in soil moisture, soil nutrients and ...

America's experience with farmland preservation is a combination of modest success and inconsistent farm policies. The successes--in terms of farmland acres preserved--have been concentrated in a relatively small number of counties, mainly in the Northeast and in California (see Sokolow and Zurbrugg, 2003). But nationwide there is a split between the farm income-oriented policies of the US fede...

Since the 1980s a series of farmland policies have been implemented in China to stabilize the balance of farmland quantity and quality against accelerating urbanization and industrialization processes. This paper aims to reveal differences of soil fertility in the farmland occupation area (FOA) and farmland supplement area (FSA). In 1985-2000 the decline of the FOA area was 181,000 ha, but the ...

This paper points out that the irrational calculation of the social security price of farmland leads to the relatively low price of the land requisition price. This paper begins with the analysis of the social security function of farmland to farmers and puts forward the idea that the social security value of farmland should include the following four aspects, namely, the value of the endowment...

Rapid urbanization has accelerated farmland transfer in China, which in turn has increased the cultivation intensity of non-grain farmland (NGF). The aim of this paper was to analyze the spatial patterns of non-grain farmland (NGF) at municipal-level cities in China from 2000 to 2014, and explore the influence of urbanization and farmland transfer on the spatial patterns of non-grain farmland (...

Prime farmland (PF) is defined as high-quality farmland and a prime farmland protection area (PFPA, including related roads, waters and facilities) is a region designated for the special protection of PF. However, rapid urbanization in China has led to a tremendous farmland loss and to the degradation of farmland quality. Based on remote sensing and geographic information system technology, thi...

Analysis of an extensive European dataset confirms the large decline of widespread farmland birds across Europe. Common farmland birds have on average fallen in number by nearly half – the most severe decline of the bird groups considered. Among the 36 species that were classified as characteristic of farmland, 20 have declined, seven have increased, four have remained stable and trends of five...

Agriculture’s farmland assessment problem has caught the attention of the Indiana General Assembly. Senate Bill 436 passed the Senate and the House by wide margins. At this writing it is in conference committee. The bill postpones use of new soil productivity factors, and more significantly limits increases in the base rate for farmland assessment for taxes in 2016 and 2017. The bill asks that ...

China has encountered serious land loss problems along with urban expansion due to rapid urbanization. Without considering complicated spatiotemporal heterogeneity, previous studies could not extract urban transition rules at large scale well. This study proposed a random forest algorithm (RFA) based cellular automata (CA) model to simulate China's urban expansion and farmland loss in a fine sc...
