Temporal and spatial distribution of egg-laying by Aedes albopictus (Skuse) (Diptera: Culicidae) was investigated in suburban neighborhoods in Raleigh, NC, by using oviposition traps (ovitraps) at fixed sampling stations during the 2002 and 2003 mosquito seasons. Variations in the phenology of oviposition between the two mosquito seasons resulted from differences in the patterns and amounts of rainfall early in the season. Aerial images of each study neighborhood were digitized, and the proportions of specific types of land cover within buffer zones encompassing ovitraps were estimated.

Community assembly rules have been extensively studied, but its association with regional environmental variation and land use history remains largely unexplored. Land use history might be especially important in Mediterranean forests, considering their historical deforestation and recent afforestation.

The Cropland Data Layer (CDL) contains crop and other specific land cover classifications obtained using remote sensing for the conterminous United States. This raster-formatted and geo-referenced product has been widely used in such applications as disaster assessments, land cover and land use research, agricultural sustainability studies, and agricultural production decision-making. The traditional CDL data distribution channels include paper thematic maps, email data requests, CD/DVD media, and ftp bulk downloading.

Silver fir (Abies alba Mill.) is a tree species distributed mainly in central Europe. It once was a dominant tree species within some forests of this region. The causes for its rapid decline in the past two centuries have not yet been sufficiently explained. It is argued that human activities have been largely responsible for expansions and contractions of silver fir populations. On the basis of the current distribution of silver fir, historical maps and palaeoecological data, we describe the expansion of silver fir forests.

This paper examines claims and conflicts in the management of the Abijata-Shalla Lakes National Park in the Central Rift Valley of Ethiopia. We used data from households, key informants (elders, park managers), and focus group discussions. Poor wildlife policy resulting in space competition between wildlife and humans (other forms of land use), limited means of revenue generation for insiders and centralized benefits from tourism have accumulated grievance and then conflict between national park authority and local communities.

Understanding how land use and land cover change influences the flow and water quality of rivers is critically important for river management and restoration. Human activities have transformed the landscapes in southern China where damaged river systems need to be restored and better managed for achieving environmental sustainability. Toward this end, we quantified the land use and land cover pattern of the Dongjiang River watershed, China between 1990 and 2006 based on remote sensing data and field measurements.

There is an increasing interest in applying fractal analysis to measure the spatial complexity of remotely sensed images. This study provides an evaluation of the effectiveness of three fractal algorithms (isarithm, triangular prism, and variogram) for characterizing urban landscapes in Indianapolis, USA, based on eight satellite images taken by five sensors (Landsat Multispectral Scanner (MSS), Landsat Thematic Mapper (TM)/Enhanced Thematic Mapper Plus (ETM+), Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER), and IKONOS).

A dried soil layer (DSL) formed in the soil profile is a typical indication of soil drought caused by climate change and/or poor land management. The responses of a soil to drought conditions in water-limited systems and the impacts of plant characteristics on these processes are seldom known due to the lack of comparative data on soil water content (SWC) in the soil profile. The occurrence of DSLs can interfere in the water cycle in soil–plant–atmosphere systems by preventing water interchanges between upper soil layers and groundwater.

Mapping urban expansion and impervious surfaces (IS) has become a useful tool for supporting watershed assessments. The lack of large-area time-series maps created the need to develop an approach and products that can easily be scaled. In this research application, 81 Landsat 1, 2, and 5 scenes for the epochs of 1975, 1985, and 1996 were used to map urban land use/land cover across New England, USA.

Soil organic carbon (SOC) is a biophysical parameter, which is also directly linked to above ground land use and land cover (LULC). Currently changes in LULC and variations in SOC often are studied and modeled separately. However, both are conjoined and should be seen as part of a cascading ecosystem framework. This is not only true for SOC but also for other biophysical parameters which are governed by human activities.

Human attitude to the land is the base for existence of humanity. It widely affects everybody– environment and landscape is changed, new buildings are constructed, new villages are developed in countryside. If such recensions aren’t planned it can cause serious problems in nearest future, considering limitedness and great significance of the land as unique resource. For correction of errors in land use immeasurable resources and decennaries are necessary. Tendencies in land use development and related problems concern to all people of Latvia, especially landowners.
