Variation in the leaf δ¹³C is correlated with salinity tolerance under elevated CO₂ concentration

Journal Articles & Books
Dezembro, 2013

Increasing atmospheric CO₂ concentration is expected to impact agricultural systems through a direct effect on leaf gas exchange and also due to effects on the global availability of good-quality water as a result of climate warming. Thus, the planning of land use for agriculture requires new tools to identify the capability of current cultivars to adapt to growth restrictions under new ambient conditions.

Crop diversification in Thailand: Status, determinants, and effects on income and use of inputs

Tailândia

Following the national policy, the Department of Agriculture of Thailand has implemented a crop diversification program in several provinces of the country. This study, which was conducted in Nakhon Pathom Province, analyzed the extent of crop diversification and its determinants using primary information collected from 245 farm households using a structured questionnaire, and from selected farmer leaders and agricultural development officials. The study also assessed the effects of crop diversification on income and the inputs used.

Land suitability analysis for Tabriz County, Iran: a multi-criteria evaluation approach using GIS

Irã

In our research we investigated the optimal utilization of land resources for agricultural production in Tabriz County, Iran. A GIS-based Multi Criteria Decision Making land suitability analysis was performed. Hereby, several suitability factors including soils, climatic conditions, and water availability were evaluated, based on expert knowledge from stakeholders at various levels. An Analytical Hierarchical Process was used to rank the various suitability factors and the resulting weights were used to construct the suitability map layers.

Combating desertification in China: Past, present and future

China

China is a developing country plagued by a long-term and large-scale desertification, which causes serious environmental problems. At the same time, China also has a long history of fighting desertification, especially in the recent decades. Thus, we think China's experience and lessons may be very important and useful for other developing countries to promote the degradation mitigation and life improvement.

En los últimos años han sido incuantificables las aplicaciones que se han llevado a cabo mediante la utilización de las denominadas Tecnologías de la Información Geográfica, bien a través del empleo de los sistemas de información geográfica (SIG), bien mediante el manejo y el análisis de imágenes de satélite (Teledetección), o bien mediante la aplicación de técnicas estadísticas de análisis multivariantes.

GIS-based integrated evaluation of environmentally sensitive areas (ESAs) for land use planning in Langkawi, Malaysia

Malásia
China

Extensive economic growth, tourism activities and over-exploitation of resources have become the common causes of environmental degradation in Langkawi. The sudden development leap resulting from UNESCO's recognition of Langkawi Archipelago as a Global Geopark in 2007, leads to continuous conflicts between enhancing environmental protection and meeting tourism and development needs.

Erosion effects on soil properties of the unique red soil hilly region of the economic development zone in southern China

Journal Articles & Books
Dezembro, 2012
China

Erosion can have a significant impact on soil properties in areas characterized by undulating topography. The spatial trends of soil properties and the availability of soil nutrients change with land use conversion. Most studies on these changes in China, however, focus on the natural or agricultural ecosystems. Little attention has been paid to unique changes, such as the conversion of natural or agricultural land to economic development zones.

Protecting Watershed Ecosystems through Targeted Local Land Use Policies

Journal Articles & Books
Dezembro, 2008

Land use change is the most pervasive force driving the degradation of watershed ecosystems. This article combines an econometric model of land use choice with models of watershed health indicators to examine the effects of land use policies on watershed ecosystems through their effect on land use. Our results suggest that incentive-based land use policies and property acquisition programs can have relatively large positive impacts on watershed health, while policies that change the returns to land use are less effective.

Conflicting rationalities, knowledge and values in scarred landscapes

Journal Articles & Books
Dezembro, 2009

Incorporating public or local preferences in landscape planning is often discussed with respect to the difficulties associated with accurate representation, stimulating interest and overcoming barriers to participation. Incorporating sectoral and professional preferences may also have the same degree of difficulty where conflicts can arise. Planning theory calls for inclusiveness and collaboration, ideally egalitarian, and analysis of the process often uses case study scenarios that may offer examples for practice and further research.

Evaluation of potential irrigation expansion using a spatial fuzzy multi-criteria decision framework

Journal Articles & Books
Dezembro, 2012

This paper presents a spatial framework which can be used to perform multi-criteria assessments for different purposes. We tested the framework on a case study of evaluating potential expansion for irrigated pasture in the Limestone Coast of South Australia. The core of the framework is the fuzzy linguistic ordered weighted averaging (FLOWA) model which integrates and implements fuzzy quantifiers, Ordered Weighted Averaging (OWA) and Analytical Hierarchy Process (AHP) in the ArcGIS environment.
