Societal drought vulnerability and the Syrian climate-conflict nexus are better explained by agriculture than meteorology

Droughts are often suspected to increase the risk of violent conflict through agricultural production shocks, and existing studies often explore these links through meteorological proxies. In Syria, an alleged agricultural collapse caused by drought is assumed to have contributed to increased migration and the conflict outbreak in 2011. Here we use satellite derived cropland and climate data to st

Field experiment and numerical simulation of point source irrigation with multiple tracers.

In this study, three plots in sandy soil in northern Tunisia were irrigated by a single irrigation dripper with a solution containing dye and bromide for three successive hours. Fifteen hours after ceasing of infiltration, horizontal 5 cm trenches were dug. Dye pattern, bromide concentration, and water content were recorded. Indication of preferential flow due to water repellency of initial dry so

On generating digital elevation models from liDAR data – resolution versus accuracy and topographic wetness index indices in northern peatlands

Abstract Global change and GHG emission modelling are dependent on accurate wetness estimations for predictions of e.g. methane emissions. This study aims to quantify how the slope, drainage area and the TWI vary with the resolution of DEMs for a flat peatland area. Six DEMs with spatial resolutions from 0.5 to 90 m were interpolated with four different search radiuses. The relationship between ac

Desert shrub stemflow and its significance in soil moisture replenishment

Stemflow of xerophytic shrubs represents a significant component of water replenishment to the soil-root system influencing water utilization of plant roots at the stand scale, especially in water scarce desert ecosystems. In this study, stemflow of Caragana korshinskii was quantified by an aluminum foil collar collection method on re-vegetated sand dunes of the Shapotou restored desert ecosystem

Groundwater geochemistry of a nitrate-contaminated agricultural site

Groundwater samples were collected from several soil depths down to 50 m below soil surface to investigate vertical profiles of NO3 − and hydrogeochemical characteristics of the experimental site. The experimental site is located in the Shimabara City, Nagasaki, Japan, where nitrate contamination in groundwater is severe due to intensive agricultural production. A transition zone regarding dissolv

Language and meaning in a multilingual interdisciplinary teaching and learning context

The present study was undertaken in the frame of the research programme Language Use and Individual Learning at the Department of Education at Lund University, using the intentional-expressive dialogue format developed within this programme. The dialogue format was adjusted to study language use and understanding in a multilingual and interdisciplinary higher education context, by including questi

Summer precipitation prediction in the source region of the Yellow River using climate indices

The summer precipitation from June to September in the source region of the Yellow River accounts for about 70% of the annual total, and its decrease would cause further water shortage problems. Consequently, the objectives of this study are to improve the understanding of the linkages between the precipitation in the source region of the Yellow River and global teleconnection patterns, and to pre

Hydrologic response of climate change in the source region of the Yangtze River, based on water balance analysis

Due to the large amount of water resources stored in glaciers, permafrost, and lakes, the source region of the Yangtze River (SRYR) is of great importance for the overall basin water flow. For this purpose, a state of art review and calculations were made for the period 1957-2013 using observed hydrological and meteorological data with a water balance approach. Actual evapotranspiration was calcul

Could changing power relationships lead to better water sharing in Central Asia?

Even though Central Asia is water rich, water disputes have characterized the region after crumbling of the Soviet Union in 1991. The uneven spatial distribution and complex pattern of transboundary water sources with contrasting national water needs have created an intricate water dilemma. Increasing national water needs, water claims by surrounding countries, uncertainties in renewable water vol

A valuable pair - candidate biomarkers RBM3 and PODXL in urothelial bladder cancer

Abstract: Bladder cancer is a heterogenous disease, ranging from minimally invasive, low-grade tumours with lowrecurrence rates and mortality on one end of the spectrum, and muscle invasive, high-grade disease prone torecurrence, progression and death at the other end.The aim of this thesis was to investigate the expression, clinicopathological correlates and prognostic significanceof the candidat

Regional sea-surface temperatures explain spatial and temporal variation of summer precipitation in the source region of the Yellow River

The summer precipitation (June–September) in the source region of the Yellow River accounts for about 70% of the annual total, playing an important role in water availability. This study divided the source region of the Yellow River into homogeneous zones based on precipitation variability using cluster analysis. Summer precipitation trends and teleconnections with global sea-surface temperatures

The effects of ocean SST dipole on Mongolian summer rainfall

Cross-correlations between inter-annual summer rainfall time series (June to August: JJA) for arid Mongolia and global sea surface temperatures (GSST) were calculated for prediction purposes. Prediction of summer rainfall for four vegetation zones, Desert Steppe (DS), Steppe (ST), Forest Steppe (FS), and High Mountain (HM) using GSSTs for time lags of 5, 6, and 7 months prior to JJA rainfall was e

The Duty of Mutual Trust in EU Law and the Duty to Secure Human Rights : Can the EU's Accession to the ECHR Ease the Tension?

The principle of mutual trust has been a central pillar of the European integration project, first as a tool for market integration, and as the European Economic Community became the European Union, as a mechanism for a more wide ranging integration of the legal orders of the member states. The EU now has legislation in place which imposes obligations on member states to trust each other's civil a

Impact of ENSO regimes on developing- and decaying-phase precipitation during rainy season in China

This study investigated the influence of five El Niño-Southern Oscillation (ENSO) types on rainy-season precipitation in China: central Pacific warming (CPW), eastern Pacific cooling (EPC), eastern Pacific warming (EPW), conventional ENSO and ENSO Modoki. The multi-scale moving t test was applied to determine the onset and withdrawal of rainy season. Results showed that the precipitation anomaly c

Assessment of Mobility Conditions Using Geographic Information System in the West Bank Territory: The Case of Bethlehem – Ramallah Route

This research paper analyses and assesses the impacts of the Israeli imposed physical obstructions on the mobility of the Palestinians in the West Bank, using a case study focused on the Bethlehem – Ramallah route. Arguably, the prevailing Israeli imposed physical obstructions, or mobility restrictions, in the West Bank territory have negative implications on the articulation of sustainable Palest

Assessment of heavy metals pollution and microbial contamination in water, sediments and fish of Lake Manzala, Egypt

The objective of this study is to assess the heavy metals pollution and microbial contamination in water, sediments and fish of Lake Manzala and study the direct and indirect effect for disposal of waste water, industrial and agricultural drainage water into the lake on the environmental situation. Samples were collected from four different sites in the lake and one site in the drain. The selected
