Despite potential evaporation rates in excess of the local precipitation, dry climates often support saline lakes through groundwater inputs of water and associated solutes. These groundwater-fed lakes are important indicators of environmental change, in part because their shallow water levels and salinity are very sensitive to weather and climatic variability. Some of this sensitivity arises f...

In this study, to study the status of water resources degradation in Kashan region, Isfahan Province, eight indices including: drop in groundwater, water salinity, irrigation efficiency, Well-to-Qanat development ratio, the pumping time, shortage of water supplies for animals and humans and the water negative balance were selected according to previous studies conducted on desertification in Ir...

Salinization is a major soil degradation threat in irrigated lands worldwide. In Portugal, it affects several pockets of agricultural areas, but the spatial distribution and intensity salinity are not well known. Unlike conventional approaches to appraise salinity, remote sensing multispectral data have great potential for detecting, monitoring, investigating problems areas. This study explores...

Salinity is an ever-increasing problem in agriculture worldwide, especially in South Asia (India, Pakistan) and Australia. Improved genotypes that are well adapted to saline conditions are needed to enhance and sustain production in these areas. A screening of 263 accessions of chickpea, including 211 accessions from ICRISAT’s mini-core collection (10% of the core collection and 1% of the entir...

Marine protist species have been used for several decades as environmental indicators under the assumption that their ecological requirements have remained more or less stable through time. However, a growing body of evidence suggests that marine protists, including several phytoplankton species, are in fact highly diverse and may quickly respond to changes in the environment. Predicting how fu...

BACKGROUND The most common way of accounting for the countryside in health studies has been to compare it, as a whole, to the city. Furthermore, most of the work on small area health inequalities has been confined to major urban centres. To counter this trend, in this paper, we explore small area health inequalities in the predominantly rural county of Portneuf (population = 44,545), Québec. Su...

A systematic review was conducted of 13 peer-reviewed articles and eight reports focused on indicators of quality abortion care. A total of 75 indicators of quality abortion were identified; these indicators address a variety of issues including policy, health systems, trained-provider availability, women's decision making, and morbidity and mortality. There is little agreement about indicators...

Possibilities of the assessment of a landscape with the use of succession development stages, monitored with the value of the Mean Individual Biomass (MIB) of carabid beetles and the occurrence of bird species are discussed on the basis of an example from Poland. Higher variability of the MIB value in space signifies a greater biodiversity. Apart from the variability of MIB, it is suggested to ...

Worldwide, contemporary measures of the success of health development programs have been mostly in terms of the reduction of mortality and morbidity as well as increasing longevity. While these goals have yielded much-needed health improvements, the subjective outcomes of these improvements, as experienced by individuals and the communities, have not been considered. Bhutan, under the overarchi...
