El objetivo del artículo será sistematizar y analizar algunas de las discusiones, planteadas como conflictos entre actores específicos, emergentes a partir de la propuesta de explotación del hierro a través de la megaminería en Uruguay. La discusión, lejos de querer analizarse en una clave simplista “megaminería si / megaminería no”, pretende abordar algunas de las implicancias de este tipo de proyecto a nivel sociopolítico, desde la perspectiva de las ciencias sociales.

Publicación revisada por paresEnero, 2016ChinaShenzhen is a city that is highly representative of China’s rapid urbanization process. As the city rapidly expands, there are enormous challenges to the sustainable use of land resources. This paper introduces the evolution of urban land expansion and the sustainable land use policy of the Shenzhen Government since 2005. The policy covers the reduction in rural-to-urban land conversion, the delineation of urban growth boundaries, arable land reclamation and the establishment of farmland protection areas, urban redevelopment, and the investigation and prosecution of illegal construction.

Publicación revisada por paresEnero, 2016ChinaLand use change (LUC) is the most dynamic force in terrestrial carbon stock change, and it is imperative to account for the dynamics of LUC in carbon stock change when forming land use policies. This paper explored the impacts of LUCs on carbon (C) stocks at a county scale and detected changes of soil C stocks within a county-scale land use planning policy. The LUCs within 1979–2006 in Fuyang County (eastern China) and Fuyang Land Use Master Planning (FLUMP) (2006–2020) were selected for this pilot study.

Publicación revisada por paresEnero, 2016GlobalQuantifying the landscape pattern change can effectively demonstrate the ecological progresses and the consequences of urbanization. Based on remotely sensed land cover data in 1994, 2000, 2006 and a gradient analysis with landscape metrics at landscape- and class- level, we attempted to characterize the individual and entire landscape patterns of Shanghai metropolitan during the rapid urbanization.

Publicación revisada por paresEnero, 2016GlobalThe redevelopment of brownfields has become an important issue, as the number of contaminated sites has been increasing. However, a comprehensive regulatory framework is lacking that includes urban planning and a sustainability plan at the national level to support brownfield redevelopment in Taiwan. Few studies have explored sustainable management objectives to reduce the environmental impact of increasing economic value of the proliferating redeveloped brownfields.

Publicación revisada por paresEnero, 2016ChinaChina has been through a period of remarkable urban sprawl since the reform and opening-up policy in 1978, with the highest urbanization occurring in the coastal zones. Sustainable urban development requires a better understanding of the spatiotemporal characteristics of urbanization. This study systematically explored urban sprawl in Chinese coastal cities with a visual interpretation method from 1979 to 2013.

Publicación revisada por paresEnero, 2016ChinaA large amount of cultivated lands in China is occupied by vacant residential areas, thereby wasting land resources and placing local food security at risk. Therefore, transforming vacant rural residential land back to its previous form is urgently required to maintain the amount of cultivated land and guarantee food security.

Publicación revisada por paresEnero, 2016ChinaDue to the multiple impacts of landform effects, spatial heterogeneity and land use policies, farmland dynamics in mountainous areas are complicated. This study investigated farmland dynamics based on land use data from a typical mountainous area, Panxi, in China for 1990, 2000 and 2010, discussed the relationship between altitude, slope and farmland changes and presented an analysis of the driving forces of farmland change. Our findings are as follows: (1) from 1990 to 2010, the area of converted farmland was relatively small (313 km2), accounting for only 2.6% of the region’s farmland.

Publicación revisada por paresEnero, 2016GlobalFacing widespread poverty and land degradation, Vietnam started a land reform in 1993 as part of its renovation policy package known as “Doi Moi”. This paper examines the impacts of improved land tenure security, via this land reform, on manure use by farm households. As manure potentially improves soil fertility by adding organic matter and nutrients to the soil surface, it might contribute to improving soil productive capacity and reversing land degradation.
