Migrants, land markets and carbon emissions in Jambi, Indonesia: Land tenure change and the prospect of emission reduction

Journal Articles & Books
Dezembro, 2014
Indonésia

Policies designed to reduce land-based carbon emissions require a good understanding of the complex connections between state-sanctioned concessions, forest conversion, informal land markets and migrants. Our case study in the peat forests of the Tanjung Jabung Barat (TanJaBar) regency of Jambi, Indonesia aimed to explore relations between four key stakeholder groups: the state, local communities, migrants, and state-sanctioned concessions.

Mapping urban land uses in the United States by census zone using nationally available data

Journal Articles & Books
Dezembro, 2013
Estados Unidos

Accurate identification of urban land use is essential for many applications. However, as physical surfaces of land-cover types are not necessarily related to their use and economic function, differentiating among thematically detailed urban land uses (single-family residential, multi-family residential, commercial, industrial, etc.) using remotely sensed imagery is a challenging task, particularly over large areas.

Estimating impervious surfaces from medium spatial resolution imagery: a comparison between fuzzy classification and LSMA

Journal Articles & Books
Dezembro, 2011
Estados Unidos

Impervious surfaces are important environmental indicators and are related to many environmental issues, such as water quality, stream health and the urban heat island effect. Therefore, detailed impervious surface information is crucial for urban planning and environment management. To extract impervious surfaces from remote sensing imagery, many algorithms and techniques have been developed. However, there are still debates over the strengths and limitations of linear versus nonlinear algorithms in handling mixed pixels in the urban landscapes.

Spatial Analysis to Site Satellite Storage Locations for Herbaceous Biomass in the Piedmont of the Southeast

Journal Articles & Books
Dezembro, 2011

Herbaceous biomass, harvested and handled as hay, has potential for bioenergy production. In the Upper Southeast, fields that cannot be competitively managed to produce another crop can produce an acceptable yield of switchgrass. Using a delayed harvest (crop is allowed to dry standing in the field), switchgrass can be harvested from production fields over a 6-month period. This gives a significant advantage over a crop residue, like corn stover, which is collected over a 5-week harvest season in the Midwest. The Southeast has the potential to be a major bioenergy production region.

Landslide Susceptibility Analysis of Shiv-Khola Watershed, Darjiling: A Remote Sensing & GIS Based Analytical Hierarchy Process (AHP)

Journal Articles & Books
Dezembro, 2012

In the present study, Remote Sensing Technique and GIS tools were used to prepare landslide susceptibility map of Shiv-khola watershed, one of the landslide prone part of Darjiling Himalaya, based on 9 landslide inducing parameters like lithology, slope gradient, slope aspect, slope curvature, drainage density, upslope contributing area, land use and land cover, road contributing area and settlement density applying Analytical Hierarchy Approach (AHA). In this approach, quantification of the factors was executed on priority basis by pair-wise comparison of the factors.

Modeling Linkages Between Climate Policy and Land Use: An Overview

Policy Papers & Briefs
Dezembro, 2007

Agriculture and forestry play an important role in emitting and storing greenhouse gases. For an efficient and cost-effective climate policy it is therefore important to explicitly include land use, land use change, and forestry (LULUCF) in economy-climate models. This paper gives an overview and assessment of existing approaches to include land use, land-use change, and forestry into climate-economy models or to link economy-climate models to land-use models.

Reform or reversal: the impact of REDD+ readiness on forest governance in Indonesia

Journal Articles & Books
Dezembro, 2014
Indonésia

Indonesia has turned its alleged role as global leader of land-based carbon emissions into a role as a global trailblazer exploring modalities for Reducing Emissions from Deforestation and Forest Degradation (REDD+). REDD+ readiness is largely about improving forest governance, but this itself is a multilayered concept. This article analyses how the processes and practices of REDD+ readiness are leading to various forest governance reforms in Indonesia.

Agricultural trade and virtual land use: The case of China's crop trade

Journal Articles & Books

China
América do Norte
América do Sul

Trade liberalization has greatly accelerated the volume of traded agricultural products in past decades. As land resources become more limited in some countries, international trade plays an important role in compensating for land scarcity in these countries. This paper aims to measure and locate the virtual land use hidden in China's imports and exports, for both primary crops and processed products, from 1986 to 2009.

impact of biofuels on the propensity of land-use conversion among non-industrial private forest landowners in Florida

Journal Articles & Books
Dezembro, 2011

A hypothetical market for renting and converting forested land into row cropping for biofuel production revealed that nearly half of the 1060 non-industrial landowners sampled in Florida are willing to accept payments for land type conversion and the resulting supply function is inelastic and positive.

Conversion of grazing land into Grevillea robusta plantation and exclosure: impacts on soil nutrients and soil organic carbon

Journal Articles & Books
Dezembro, 2014

Different studies have shown that the effect of land use conversion on soil nutrients and soil organic carbon (SOC) is variable, which indicates that more investigations that focus on different specific geographical locations and land use types are required. The objectives of this study were (1) to evaluate the effect of grazing land (GL) conversion into Grevillea robusta plantation and exclosure (EX) on soil nutrients and soil organic carbon (SOC) and (2) to examine the impact of soil organic matter (SOM) on soil nutrients.
