One of the main resonator factors in watershed soil erosion is inappropriateland management including conversion of pasture land to dry-land farming.Unfortunately, the changes of Gara Su watershed usages have been very common.Thus, in order to understand the influence of land use on runoff rate and soil loss, soillosses were investigated and determined under both pasture and dry-land agricultur...

A combined intervention of strength and endurance training is common practice in elite swimming training, but the scientific evidence is scarce. The influences between strength and endurance training have been investigated in other sports but the findings are scattered. Some state the interventions are negative to each other, some state there is no negative relationship and some find bisected a...

AIM This study provides regional estimates of forest cover in dry African ecoregions and the changes in forest cover that occurred there between 1990 and 2000, using a systematic sample of medium-resolution satellite imagery which was processed consistently across the continent. LOCATION The study area corresponds to the dry forests and woodlands of Africa between the humid forests and the se...

BACKGROUND Animal trypanosomosis is one of the major disease problems affecting agricultural productivity in Ethiopia. The impact of the disease is believed to vary with season and agro-ecologies in line with fly vector distribution. A cross-sectional study on bovine trypanosomosis was conducted from November 2015 to June 2016, in seven selected villages of Gidami district, Oromia Regional Stat...

in order to study the effect of strip intercropping of maize (zea mays l.) and bean (phaseolus vulgaris l.) on the dry matter yield and land equivalent ratio (ler) in weedy and weed free treatments, an experiment was conducted at the agricultural station of college of agriculture, ferdowsi university of mashhad, iran. treatments were strip width of 2, 3, 4 and 5 rows and sole cropping of each c...

The Lagoon of Fuente de Piedra in Andalusia, Spain, is a high-value habitat for waterbirds, threatened by expansion and irrigation of olive plantation. This research focuses on detecting the response of land-cover in the lake to water level variation using multi-temporal satellite data, so as to provide information for the nature park management. Objectives of this study are to identify the lan...

China has abundant crop residues (CRE) that could be used for bioenergy. The spatiotemporal characteristics of bioenergy production are crucial for high-efficiency use and appropriate management of bioenergy enterprises. In this study, statistical and remote-sensing data on crop yield in China were used to estimate CRE and to analyze its spatiotemporal changes between 1990 and 2010. In 2010, Ch...

Soil is the largest pool of terrestrial organic carbon in the biosphere and interacts strongly with the atmosphere, climate and land cover. Remote sensing (RS) and geographic information systems (GIS) were used to study the spatio-temporal dynamics of croplands and soil organic carbon density (SOCD) in the Sanjiang Plain, to estimate soil organic carbon (SOC) storage. Results show that cropland...
