[1] European water policy requires all EU Member States to implement volumetric water pricing at rates that roughly cover the total costs of providing water services. The objective of this paper is to develop a methodology that will enable us to analyze the differential impact that a water pricing policy for irrigation would have on heterogeneous farmers of an irrigated area. For this purpose, ...

The introduction of irrigation to agrarian areas involves several environmental changes that can be aggravated by physical and agronomic factors. The aim of this study is to analyze the spatiotemporal dynamics of the environmental impact on water resources that result from the transition of an agrarian basin into an irrigated area. During five hydrological years, a spatiotemporal comparison was...

The hydrological response to land cover changes induced by human activities in arid regions has attracted increased research interest in recent decades. The study reported herein assessed the spatial and quantitative changes in surface runoff resulting from land cover change in the Al-Baha region of Saudi Arabia between 1990 and 2000 using an ArcGIS-surface runoff model and predicted land cover...

The rice land is linked to the climate change due to its methane emission potential. The systems of growing rice and associated soil and crop management practices that have evolved are varied and complex. However, from the methane emission point of view, water regime is a crucial parameter. According to IPCC guidelines the rice ecosystem need to be categorized into four strata for methane emiss...

Anophelism without malaria has long been recognized. In large irrigation projects, such as that around Niono, Mali, villages in irrigated areas sometimes have more anopheline vectors of malaria than adjacent nonirrigated villages, but overall malaria prevalence is substantially less. One hypothesized explanation for this is high anopheline densities lead to smaller adults, who do not live so lo...

Over the last 50 years, the most increase in cultivated land area globally has been due to a doubling of irrigated land. Long-term agronomic management impacts on soil organic carbon (SOC) stocks, soil greenhouse gas (GHG) emissions, and global warming potential (GWP) in irrigated systems, however, remain relatively unknown. Here, residue and tillage management effects were quantified by measur...

Finger millet landraces viz., TZA-01 and TZM-01 were grown in glasshouses under two moisture regimes (fully irrigated and after drought) to investigate the effects of environmental stress on the growth, SPAD measurement, radiation use efficiency and yield of finger millet (Eleucine coracana). The drought treatment was imposed at 28 DAS beyond which no irrigation was applied to the droughted tre...

The objectives of this work were to determine the heliotropic movements of the upper trifoliates for two soybean cultivars, BR 16 and Embrapa 48, during a daily cycle, in three phenological stages and two water regimes, and to estimate the impact of irrigation and daily leaflet movements on agronomic characteristics and grain yield. Heliotropic movements were studied in three phenological stage...

Incidence S. nasale (causative agent of nasal schistosomiasis) in graded murrah buffaloes was studied. 4(8%) among healthy and 46(92%) among suspected buffaloes were diagnosed with nasal schistosomiasis. Area under investigation was highly irrigated giving ample scope for exposure of animals to cercaria of S. nasale. Buffaloes showing signs of reduced water intake, reduced milk yield, normal bo...

Pulmonary sequestration is defined as a mass of lung tissue separated from the tracheobronchial tree and irrigated by an anomalous systemic artery. It is rarely seen in conjunction with lung neoplasms. We report the case of a 39-year-old female patient diagnosed with a carcinoid tumor, located in the intermediate bronchus and accompanied by bronchiectasis in the right lower lobe. The patient un...
