The preservation of farmland is a growing concern in China because the fact that China possesses limited land resources and the world's largest population presents a clear contradiction. Only when the value of farmland is fully appreciated in commercial markets can farmland preservation be effectively achieved. The current study constructed a model to evaluate the economic, social, and ecological value of farmland in China according to the connotation of values. As a case study, the value of Chinese farmland was estimated in 1999, 2002, 2005, 2008, and 2011 using the established model. Although the amount of farmland was greatly reduced from 1999 to 2011 due to constructive occupation, agricultural restructuring, ecological restoration, and disaster destruction, the value of this farmland increased from 220.71×1012 to 736.26×1012 RMB Yuan as a result of the multifunctional nature and scarcity of farmland during the same period. The potential value of farmland in China was huge, but the value in the market was greatly underestimated, especially in regard to its social and ecological value. This study proposes a new method that integrates the discounted value of all future services provided by a natural resource(for the society and individuals) to evaluate the resource assets, provides a scientific foundation for the preservation and operation of farmland assets, and explores ways to increase farmers' property income. 展开更多

Farmland merging is a significant tool in comprehensive rural areas development. Although a broad range of research relating to this field already exists, not enough emphasis has yet been placed on this issue in Poland. In all probability it would not be a point for broad discussion if this situation related to a country, where agriculture is negligible. Nonetheless, in Poland agriculture plays a very important role in the economy: it employs 17% of labour force and arable land covers about 60% of the total area. Yet, even where land consolidation work has been carried out for years, the expected effects are still not appreciable, mostly because of the disastrous formal and legal policy. This paper intends to make a contribution to the field of knowledge of farmland merging in Poland. Particular attention was focused on the importance of land management policy in the streamlining of land consolidation activities. The study brings a fresh view on the examination of the effectiveness of farmland merging work, based on two different formal procedures carried out in Poland. During the investigation the main obstacles and weaknesses in legal regulation were revealed while at the same time, producing possible solutions. 展开更多
