Complex changes in carbon sources and sinks caused by rapid urbanization have been observed with extensive changes in the quantity, structure, and spatial pattern of land use types. Based on the modified Carnegie-Ames-Stanford Approach model and on gray relational analysis, we analyzed the influence of land use changes on carbon sinks and emissions in Guangzhou from 2000 to 2012. The aim was to identify suitable options for built-up land expansion that would allow for minimal carbon losses.

In September of 1994, the Army closed the Fort Ord Military Reservation, a Superfund site of some 28,000 acres located in Monterey County, California. Under the Base Closure and Realignment Act, nearly all of this land will be transferred to federal and state entities and to a number of cities of the Monterey peninsula that border the base. A good deal of this property is valuable real estate -- coastal dunes, golf courses, and barracks that can be converted to apartments or dormitories.

The mountains of northern Vietnam have lost significant forest cover during the last decades due to the conversion from natural vegetation to cultivated land, leading to the depletion of soil organic matter and land degradation. The study evaluated bamboo as an alternative cropping strategy in the northern central upland of Vietnam. We analyzed above-ground carbon fixing capacity of bamboo, accumulation of soil organic carbon, and socio-economic aspects as compared to other land use systems.

We used the process-oriented niche model CLIMEX to estimate the potential global distribution of serrated tussock under projected future climates. Serrated tussock is a drought-tolerant, wind- and human-dispersed grass of South American origin that has invaded pastures in Australia, Europe, New Zealand, and South Africa. The likely effect of climate change on its potential global distribution was assessed by applying six climate-change scenarios to a previously developed model.

Food security remains an ongoing global concern: the challenge of ensuring food availability, access, and utility for all, at all times, is yet to be met. The body of literature relating to food security is growing immensely. Land administrators are part of the discourse. Their arguments are spread disparately across academic and professional publications. The distinction between scientific work and political rhetoric is increasingly blurry: the role of land administration needs to be more concisely articulated.

Climate change and energy saving are challenging the city and the territorial organization. Innovative spatial and urban planning methods and procedures are required, and new approaches and instruments must be elaborated and applied in order to shift from the building scale to the urban and territorial ones.

In Burkina Faso, livestock sedentarization programmes are still at the top of policy makers’ agendas and at the heart of their discourse, despite huge changes in land cover, land use and territorialities in rural areas. This paper contributes to the literature on the impact of livestock policies targeting the sedentarization of pastoralism in sub-Saharan Africa by specifically highlighting the territorial consequences of such policies.

In the past few decades there has been an increasing pressure of population all over the world, especially in India, resulting in the utilization of every available patch of available land from woodlands to badlands. The study area represents a basin which is economically growing fast by converting the fallow lands, badlands and woodlands to agricultural land for the past few decades.

Notions of land cover relating to physical landscape characters are readily captured by satellite imagery. Land use on the other hand relates more to the societal aspects of a landscape. We argue that much of the spatial configuration of landscape characters is related to land use and that satellite data can be used to represent and investigate interpretations of land use. We propose and demonstrate the joint use of a novel SRPC procedure for satellite imagery together with an explicit representation of category semantics.

This study presents spatial and temporal changes of carbon storages of forest timber biomass in a typical forest management unit of the northeastern part of Turkey. The effects of land-use and land-cover changes on the amount of carbon storage are analyzed. Temporal changes of carbon storage of the area were estimated using forest inventory data. The spatial distribution of carbon densities was mapped using Geographic Information Systems (GISs). As an overall change between 1984 and 2005, there was a net increase of 12,379 ha in forested areas.
