Land-use planning of Minoo Island, Iran, towards sustainable land-use management

Journal Articles & Books
Dezembro, 2011
Irã

Land-use planning is one aspect of sustainable development that determines the integrity of socioeconomic and ecological nuance. Land evaluation is an approach to sustainable land-use planning, which predicts the capability of the land-use system. This means that a specific land area should be under specific use, considering certain factors and characteristics of the land and its location. In other words, lack of proper information on land capability and rational and irrational use of land leads to destruction of land resources.

ASSESSEMENTS OF ROMANIAN FARMS’ ECONOMIC PROFILE, THROUGH SAMPLE SURVEY ON SUSTAINABLE LAND USAGE

Journal Articles & Books
Maio, 2009

A fundamental element in designing sustainable rural development strategies consists in evaluation the economic capacity of the production structures in agriculture. Since land use is a primary determinant of ecosystem vulnerability, affecting the soil regeneration, biodiversity, or landscape, the paper aims at investigating the economic potentials conferred by the agricultural area usage in the Romanian farms.

Pathways and pitfalls of implementing the use of woodfuels in Germany's bioenergy sector

Journal Articles & Books
Dezembro, 2009
Alemanha

The paper presents an empirical study on the use of woody biomass for energy supply in Germany and the federal state of Brandenburg. It aims to explain the role forestry enterprises have for bioenergy provision in this area. The 'Institutions of Sustainability' framework is used as an analytical tool to investigate the role of private and public actors in these transactions, respectively, in the governance structures they are subject to. Empirical evidence was gathered by in-depth interviews with actors from forestry and bioenergy practice.

Estimates of technically available woody biomass feedstock from natural forests and willow biomass crops for two locations in New York State

Journal Articles & Books
Dezembro, 2009

A Geographic Information System (GIS) was used to estimate the technically available woody biomass from forests and willow biomass crops within a 40 km radius of Syracuse and Tupper Lake, NY. Land cover and land use data were used to identify the available land base and restrictions were applied for slope, parcel size and designated wetlands. Approximately 222,984 oven-dry tonnes (odt) of forest biomass are technically available annually around Syracuse, from 165,848 hectares (ha) of timberland.

Soil degradation and food security coupled with global climate change in northeastern China

Journal Articles & Books
Dezembro, 2013
China

The northeastern China is an important commodity grain region in China, as well as a notable corn belt and major soybean producing area. It thus plays a significant role in the national food security system. However, large-scale land reclamation and non-optimum farming practices give rise to soil degradation in the region. This study analyzed the food security issues coupled with global climate change in the northeastern China during 1980–2000, which is the period of modern agriculture.

Optimisation of the traditional land-use system in the Angolan highlands using linear programming

Journal Articles & Books
Dezembro, 2014

This study used linear programming (LP) to analyse land-use alternatives in the traditional Umbundu farming system in the Angolan central highlands. Farmers of the region have traditionally produced maize and pulses for subsistence and vegetables and timber as cash crops. Different pasture and forest fallow rotations are used along catena production sites. The system is labour-intensive and uses animal traction. LP problems were formulated and solved for a baseline land-use alternative, improved diet alternative and maximal timber production alternative.

Projected climate change impacts on spatial distribution of bioclimatic zones and ecoregions within the Kailash Sacred Landscape of China, India, Nepal

China

Rapidly accelerating climate change in the Himalaya is projected to have major implications for montane species, ecosystems, and mountain farming and pastoral systems. A geospatial modeling approach based on a global environmental stratification is used to explore potential impacts of projected climate change on the spatial distribution of bioclimatic strata and ecoregions within the transboundary Kailash Sacred Landscape (KSL) of China, India and Nepal.

Land property, tenure security and credit access: a historical perspective of change processes in China

Policy Papers & Briefs
Dezembro, 2006
China

The North China Plain is the country's granary: most of wheat and maize is supplied by this region in the northeast of China. Intensity of agricultural production has risen sharply in the last decades and the negative environmental effects like water scarcity, salinization and nitrate contamination have been widely acknowledged. In the wake of the country's rapid economic development it becomes at the same time more and more urgent to narrow the gap between the well-being of the urban and rural population.

equilibrium analysis of the land use structure in the Yunnan Province, China

Global

Global land use structure is changing rapidly due to unceasing population growth and accelerated urbanization, which leads to fierce competition between the rigid demand for built-up area and the protection of cultivated land, forest, and grassland. It has been a great challenge to realize the sustainable development of land resources.

Ecological restoration planning based on connectivity in an urban area

Journal Articles & Books
Dezembro, 2012

In urban areas, the competition between land development and ecological conservation is intense. To mitigate the negative effects of urbanization, we developed a methodology to plan a spatially explicit conservation network based on widely available remotely sensed data and other auxiliary data. First, as an area of strategic significance for the conservation of regional flora and fauna and for maintaining high environmental quality to promote human well-being, the remaining natural and semi-natural areas were identified as ecologically primary areas.

IMPACTS OF PROGRAMS AND ORGANIZATION ON THE ADOPTION OF SUSTAINABLE LAND MANAGEMENT TECHNOLOGIES IN UGANDA

Policy Papers & Briefs
Dezembro, 2003
Uganda

The government of Uganda is currently decentralizing many of its services including those directly related to agriculture and the environment. Non-government organizations (NGOs) and community-based organizations (CBOs) are being asked to take the lead in the provision of government services such as agricultural extension during the transition to demand driven fee-for-service. This paper explores the role of government programs, NGOs and CBOs in the adoption of land management technologies.
