The health and productivity of global land resources are declining, while demand for those is increasing. aim degradation neutrality (LDN) to maintain or enhance land-based natural capital its associated ecosystem services. Scientific Conceptual Framework Land Degradation Neutrality has been developed provide a scientific approach planning, implementing monitoring LDN. Science-Policy Interface the United Nations Convention Combat Desertification (UNCCD) led development conceptual framework,...
Higher yields and reduced pesticide impacts are needed to mitigate the effects of agricultural intensification. A 2-year farm-scale evaluation 81 commercial fields in Arizona show that use transgenic Bacillus thuringiensis (Bt) cotton insecticide use, whereas with Bt protein herbicide resistance (BtHr) did not affect use. Transgenic had higher yield than nontransgenic for any given number applications. However, nontransgenic, BtHr similar overall, largely because improved control key pests....
Due to the challenges faced by resource managers in maintaining post-fire ecosystem health, there is a need for methods assess ecological consequences of disturbances. This research examines an approach assessing changes vegetation dynamics sites Spain, Israel and USA that burned 1998, 1999 2002 respectively. Moderate Resolution Imaging Spectroradiometer satellite Normalized Difference Vegetation Index (NDVI) time-series data (2000–07) are used all characterise track seasonal spatial...
Research from multiple domains has provided insights into how neighborhood design can be improved to have a more favorable effect on physical activity, concept known as walkability. The relevant research findings/hypotheses been integrated Walkability Framework, which organizes the elements nine walkability categories. purpose of this study was test whether conceptual framework used model measure interactions between built environment and activity. We explored correlations categories...
Neighborhood design affects lifestyle physical activity, and ultimately human wellbeing. There are, however, a limited number of studies that examine neighborhood types. In this research, we four types designs: traditional development, suburban enclosed community, cluster housing assess their level walkability effects on activity We significant associations through questionnaire (n = 486) distributed in Tucson, Arizona using the Walkability Model. Among tested types, development showed...
BACKGROUND/OBJECTIVES:The Recaller app was developed to help individuals record their food intakes.This pilot study evaluated the usability of this new picture application (app), which operates on a smartphone with an embedded camera and Internet capability.SUBJECTS/METHODS: Adults aged 19 28 years (23 males 22 females) were assigned use six designated, nonconsecutive days in order capture image each meal snack before after eating.The images automatically time-stamped uploaded by website.A...
Abstract Surface roughness is a key parameter of radar backscatter models designed to retrieve surface soil moisture (θS) information from images. This work offers theory‐based approach for estimating parameter, termed the correlation length (L c). The L c in centimetres point on ground short distance which heights rough are correlated with each other. based relation between and h RMS as theorized by Integral Equation Model (IEM). another root mean squared height variation surface....
This study sought to determine if knowledge regarding the risk for knee injuries and potential their prevention is being translated female adolescent soccer players (13–18 years), parents, coaches. Eligible participants in 2007 indoor season were surveyed of prevent injuries, effective strategies, they felt that injury was possible. Team selection stratified be representative both competitive recreational level play age group distributions within selected association. Of subjects, 773/1396...
Prevailing city design in many countries has created sedentary societies that depend on automobile use. Consequently, architects, urban designers, and land planners have developed new theories, which been incorporated into the Leadership Energy Environmental Design for Neighborhood Development (LEED-ND) certification system. The LEED-ND includes elements improve human well-being by facilitating walking biking, a concept known as walkability. Despite these positive developments, relevant...
Vellozia sincorana L.B. Sm. & Ayensu, an endemic of campos rupestres, is endangered species collected by local people to start cooking fires due the flammability its resinous stems. A massive flowering V. following a wildfire in October 1999 raised some questions: Does fire affect and fruiting sincorana? Is height individuals correlated with fruit production? event on 8 November 2008 provided opportunity explore these questions. Two populations two rupestres sites (12º31'S - 41º29'W;...
Land management evaluation can be made more relevant and holistic by incorporating local knowledge perspectives. We examined whether photo elicitation photovoice could enhance semi-structured interviews in capturing livestock farmers' perspectives a participatory Mier Molopo, South Africa. The participants discussed themes including veld condition, land management, criteria. Photo provided details (62% of instances analyzed [Mier]; 58% [Molopo]) new information (75% 65% beyond those...
Values associated with scenic beauty are common “pull factors” for amenity migrants, however the specific landscape features that attract migration poorly understood. In this study we focused on three visual quality metrics of intermountain West (USA), objective exploring relationship between location exurban homes and aesthetic preference, as exemplified through greenness, viewshed size, terrain ruggedness. Using analysis, compared viewsheds actual houses to randomly-distributed simulated...
This study analyses the effect of successional stage after farmland terrace abandonment on post-fire plant recovery in a Mediterranean landscape. Specific objectives were to (1) compare fuel characteristics and fire severity three stages – dry grassland, dense shrubland pine stands; (2) analyse pre-fire vegetation (3) relative vulnerability (i.e. potential for ecosystem shift soil degradation) wildfires stages. We assessed 30 abandoned terraces (15 unburned 15 burned), with diverse stages,...
