Inverting the impacts: Mining, conservation and sustainability claims near the Rio Tinto/QMM ilmenite mine in Southeast Madagascar

Journal Articles & Books
Dezembro, 2012

This paper traces a genealogy of land access and legitimization strategies culminating in the current convergence of mining and conservation in Southeast Madagascar, contributing to recent debates analyzing the commonalities and interdependencies between seemingly discrete types of land acquisitions.

role of vegetation analysis by remote sensing and GIS technology for planning sustainable development: A case study for the Santos estuary drainage basin (Brazil)

Journal Articles & Books

Brasil

The role of vegetation analysis by remote sensing (RS) and Geographical Information System (GIS) technology to support plans for sustainable development is discussed through a proposal of an index of ecosystem “integrity” or of regeneration capacity. The index is based on the vegetation “mass” of a given land cover type and the capacity that such mass has to contrast soil erosion. The index is therefore taking into account the effects of human activities and not merely the state of ecosystems in terms of their components.

Policy Analysis for Sustainable Land Management and Food Security in Ethiopia: A Bioeconomic Model with Market Imperfections Food Security in Ethiopia

Soil fertility and the lack of fertilizer use in Africa are frequently discussed topics. Theproblems of land degradation and low agricultural productivity, which result in foodinsecurity and poverty, are particularly severe in the rural highlands of Ethiopia. Inmany areas, a downward spiral of land degradation and poverty appears to be occurring. Findingsolutions to these problems requires identifying effective entry points for farmers, governments,and civil society organizations, and understanding the potential impacts and tradeoffsthat are likely to arise from alternative interventions.

Using species distribution modeling to improve conservation and land use planning of Yunnan, China

Journal Articles & Books

China

Part of the Himalayan biodiversity hotspot, Yunnan province in China is a highly diverse terrestrial region, particularly in the wide range of natural forest types. These forests are under considerable conversion pressure as land use intensifies with expanding human population and economic development. Conservation strategies based on the geographic patterns of botanical species richness, including the identification of meaningful floristic regions and priority areas for conservation, could improve the effectiveness of forest policy and management.

Soil properties and their spatial pattern in an oasis on the lower reaches of the Tarim River, northwest China

Journal Articles & Books
Dezembro, 2010
China

In this study, classical, geostatistical methods and a geographical information system have been used to identify soil properties including soil organic carbon (SOC), total nitrogen (total N), salt content (SC) and soil moisture (SM), and their spatial variation as well as their relationships with groundwater, land use, and soil texture. The data came from 36 soil samples from 0 to 20cm depth, and 36 groundwater samples in the Tikanlik Oasis on the lower reaches of the Tarim River, northwest China.

Regulating industrial forest concessions in Central Africa and South America

Journal Articles & Books

América do Sul
África Central

Tropical countries face special specific problems in implementing sustainable forest management (SFM). In many countries, questions are raised on whether tropical forests should be publicly, commonly or privately owned and managed in order to enhance sustainability. Other debates also focus on whether small-scale enterprises are better positioned than large-scale industrial concessions to reduce poverty and attain sustainable management.

Categorising farming practices to design sustainable land-use management in mountain areas

Europa

In European mountain areas, shrub encroachment resulting from farmland abandonment is most often managed by mechanical operations such as roller chopping or controlled burning, which have proved to be ineffective and unsustainable. Recent agroecological findings highlight the potential impact of grazing on long-term shrub dynamics. We thus explored the potential contribution of livestock farms to the management of shrub encroachment.

Land cover and land use change related to shrimp farming in coastal areas of Quang Ninh, Vietnam using remotely sensed data

Vietnam

Rapid development of shrimp farming may lead to unrecognized and undesirable changes of land cover/land use patterns in coastal areas. Of special concern is the loss of mangrove forest in coastal areas such as Quang Ninh, Vietnam, which is adjacent to the World Heritage-listed Ha Long Bay. Understanding the status and changes of land cover/land use for coastal shrimp farms and mangrove forests can support environmental protection and decision-making for sustainable development in coastal areas.

new model for sustainable development: a case study of The Great Bear Rainforest regional plan

Journal Articles & Books
Dezembro, 2010
Canadá

This paper describes a new model of sustainable development planning based on a case study of a successful planning process for the Great Bear Rainforest on Canada's west coast. The planning region is an area of international ecological significance that contains one-quarter of the world's remaining ancient coastal temperate rainforest. An innovative collaborative planning process was initiated in 1996 to develop a plan for the region that balances social, economic, and environmental values.

Sustainable development ability of grain production in Sichuan Province

China

We set up the evaluation index system of the sustainable development ability of grain production on the basis of the overall analysis of grain production trend in Sichuan Province. And then we evaluate the sustainable development ability of grain production from 1990 to 2006 in Sichuan Province by adopting the method of principal component analysis. Result shows that the sustainable development ability of grain production has improved steadily, but there are some hidden troubles such as frequently changes of grain yield and gradually decrease of total farmland.

Northeast Asia is an area with relative concentrations of resources, a complex ecological environment pattern, and a marked human—land contrast relationship. This area has significance for analyzing land cover patterns and variations for regional sustainable development among the trans-boundary areas of China, Russia, and Mongolia. In this paper, the transect analysis research tool and transfer matrix method are used to capture the regional land cover change characteristics by using Moderate Resolution Imaging Spectroradiometer(MODIS) datasets recorded from 2001 to 2012.

Linking long-term gully and river channel dynamics to environmental change using repeat photography (Northern Ethiopia)

Journal Articles & Books
Dezembro, 2011

In the Highlands of Northern Ethiopia gully occurrence is linked to poverty-driven unsustainable use of the land in a vulnerable semi-arid and mountainous environment, where intensive rainfall challenges the physical integrity of the landscape. Trends in gully and river channel erosion, and their relation to triggering environmental changes can proffer valuable insights into sustainable development in Northern Ethiopia.
