feature extraction software tool for agricultural object-based image analysis

Journal Articles & Books
Décembre, 2011

A software application for automatic descriptive feature extraction from image-objects, FETEX 2.0, is presented and described in this paper. The input data include a multispectral high resolution digital image and a vector file in shapefile format containing the polygons or objects, usually extracted from a geospatial database.

Systematic and random transitions of land-cover types in Burkina Faso, West Africa

Afrique occidentale

In-depth statistical analysis of forest transition between land-cover types over time can reveal the dominant signals of landscape transformation, which are needed in order to develop appropriate land management strategies. We applied a recently developed methodology to analyse the transition matrix of six land-cover classes, derived from 1986 and 2002 Landsat images of an area of 15 675 km² in southern Burkina Faso. Results show that most landscape transformations followed a systematic process.

Long‐term avian community response to housing development at the boundary of US protected areas: effect size increases with time

États-Unis d'Amérique

Biodiversity conservation is a primary function of protected areas. However, protected areas also attract people, and therefore, land use has intensified at the boundaries of these lands globally. In the USA, since the 1970s, housing growth at the boundaries (

Changes of forest coverage and land uses as assessed by the inventory of land uses in Italy

Journal Articles & Books
Juillet, 2012
Italie

The paper presents the IUTI program, a land use inventory of Italy, based on point sampling. It has been carried out to support the National Carbon Sink Accounting Register and it was realized within the framework of the Italian National Remote Sensing Plan managed by the Italian Ministry of Environment. IUTI has monitored the land use and land use change and forestry in the last two decades over the country at the years 1990, 2000, 2008, adopting a tessellated stratified sampling scheme with about 1.2 million sample points on aerial orthophotos.

Using a Logistic Regression Model to Analyze Alley Farming Adoption Factors in Sierra Leone

Journal Articles & Books
Décembre, 2016
Sierra Leone

Slash-and-burn shifting cultivation is the conventional farming practice in Sierra Leone, where communal land tenure is by far the most common form of land use. Alley farming, the alternative agricultural system, has been introduced as a technical option to increase yield, reduce or eliminate fallow and conserve soil water. This study uses a logistic regression model to determine the factors influencing the adoption of alley farming in Sierra Leone.

Cashew nut production in Indian subcontinent with emphasis on carbon sequestration potential in a changing global climate scenario

India has a maximum area (21.6%) under cashew nut and is the third largest producer (17.3%) of raw nuts in the world. The country is the second largest exporter, accounting for 34% of the world’s export of cashew kernels having a comparative advantage in production and processing on account of its cheap and skilled labour force. The yields in India are poor at 860 kg/ha as compared to 4,125 kg/ha in Vietnam and 2,000 kg/ha in Nigeria.

Spatiotemporal analysis of land-use and land-cover change in the Brazilian Amazon

Journal Articles & Books
Décembre, 2013

This paper provides a comparative analysis of land-use and land-cover (LULC) changes among three study areas with different biophysical environments in the Brazilian Amazon at multiple scales, from per-pixel, polygon, census sector, to study area. Landsat images acquired during the years of 1990/1991, 1999/2000, and 2008/2010 were used to examine LULC change trajectories with the post-classification comparison approach.

Institutionalization of common land property in Portugal: Tragic trends between “Commons” and “Anticommons”

Journal Articles & Books
Décembre, 2013
Portugal

The use and exploitation of natural resources is generally structured by institutions, especially by property institutions. The main objective of this paper is to present a diachronic analysis of the institutionalization of common land property in Portugal. The several types of ownership may be largely explained by common land history. We intend to draw an outline of the emergence, evolution and transition of common land from the late nineteenth century to the present day, using the matrix proposed by Heller.

Opportunities for fire and carbon on pastoral properties in the savanna rangelands: perspectives from the Indigenous Land Corporation and the Northern Territory Cattlemen’s Association

Australie

Understanding both the carbon dynamics within Australia’s northern savannas and the opportunities presented through diversification into carbon markets is of relevance to pastoral land managers both in Australia and globally. The Indigenous Land Corporation (ILC), through its role in assisting Indigenous people to acquire and manage land for cultural, social, environmental and economic benefits, has operated in the carbon market and is keen to continue working with its partners to explore the opportunities to develop and broaden this further.

Impacts of innovative forestry land use on rural livelihood in a bimodal agricultural system in irrigated drylands

The conversion of marginal croplands to tree plantations, as an option to address climate change, land degradation, and irrigation water scarcity, as well as to improve the welfare of local population requires prior analysis.

European scale analysis of phospholipid fatty acid composition of soils to establish operating ranges

Journal Articles & Books
Décembre, 2016

Recent preoccupations regarding possible negative effects of pollution, inappropriate land management, climate change, desertification, erosion, compaction or over-exploitation on soils has led to initiatives for the survey of soils. One of them, EcoFINDERS, launched a pan-European survey in order to define normal operating ranges for soil biodiversity and quality, through the use of several methodologies.

Regional land-use allocation with a spatially explicit genetic algorithm

Chine

Land-use allocation is an important way to promote the intensive and economic use of land resources and achieve the goal of sustainable development. It is a complex spatial optimization problem, and heuristic algorithms have been one of the most effective ways to solve it in past studies. However, heuristic algorithms lack the guidance of planning knowledge, which makes land-use patterns usually unreasonable in practice. This research proposes a spatially explicit genetic algorithm (SEGA) that integrates land-use planning knowledge with the genetic algorithm (GA).
