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...

Most policies designed to reduce land fragmentation involve consolidation. However, research examining the relationship between agricultural zoning and has not yet been explored. This paper considers causal impact of an anti-land policy on farmland use farm production inputs relevant environmental quality using a population-based census survey households in Taiwan. Using regression discontinuit...

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...

To improve the stability of sloping farmland, optimum ratio for parameter composite soils was determined. Plain and mixed were prepared with three improved materials glutinous rice glue, wood fibres coarse sand laboratory to tests experiments. For different moisture soil contents, shear strength, cohesion internal friction angle analysed proportions adjusted based on suitability plant growth. S...

Land consolidation projects play an important role in promoting agricultural land use transitions, ensuring national food security, and accelerating the construction of ecological civilization. The Loess Plateau China is a typical ecologically fragile area, where Gully Consolidation Project (GLCP) has been implemented recently had major impact on local safety. In this study, we established quan...

Land consolidation is an instrument that readjusts land parcel shapes and reallocates rights in order to minimize farmland fragmentation, optimize agricultural output, generate optimal living working conditions rural areas. The optimization reallocation algorithms typically rely on monetarized values of parcels, soil quality, compensation amounts. Yet, management interventions also need instrum...

Farmland conversion, i.e. conversion of farmland into non-agricultural construction land, is an unavoidable trend in global economic development(Fazal 2001; Tan et al. 2005; Bugri 2008). In China, which is relatively short of farmland resources and yet in the phase of accelerating urbanization, conversion of farmland is closely related to national food security, ecological security as well as s...

A series of soil conservation measures have been carried out to reduce soil loss on the Loess Plateau of China since 1950s, and the biologic measures were implemented according to topographic factors such as slope and elevation; therefore, the changes in topographic factors of land use can indicate the effects of the biologic measures. The objectives of this study were to (i) analyze the land u...
