États-Unis d'Amérique

BACKGROUND: Recent evidence indicates that some populations of European corn borer (ECB), Ostrinia nubilalis (Hübner), have declined to historic lows owing to widespread adoption of Bt corn hybrids. To understand current ECB populations in Pennsylvania field corn, the authors assessed larval damage in Bt and non‐Bt corn hybrids at 29 sites over 3 years. The influence of Bt adoption rates, land cover types and moth activity on levels of ECB damage was also considered.

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

Indonésie

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.

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 (

États-Unis d'Amérique

SUMMARYThis paper analyses the differences between forestland tenure systems in Canada and the US. Evolution of the two systems is primarily explained by variation of scarcity and land productivity. In early colonial times, Canada's economy was tightly linked to the fur trade with Indian people, while New England's economy was based more on agriculture with more intensive land use.

Effects of urbanization and industrialization on agricultural land use in Shandong Peninsula of China

Chine

China is the most populated country in the world with slightly more than half of the population is still living in rural areas. In the past couple of decades, rapid urbanization and industrialization have significantly changed the land use/land cover (LULC) pattern in rural areas, particularly those around the big cities in eastern China. Shandong Peninsula, a traditional agriculture area, also has witnessed rapid urbanization and industrialization.

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.

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.

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

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

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.

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.
