This article assesses insurance uptake in three community-based health insurance (CBHI) schemes located in rural parts of two of India's poorest states and offered through women's self-help groups (SHGs). We examine what drives uptake, the degree of inclusive practices of the schemes and the influence of health status on enrolment. The most important finding is that a household's socio-economic...

This study explores how catchment heterogeneity and variability can be summarized in simplified models, representing the dominant hydrological processes. It focuses on Mediterranean catchments, characterized by heterogeneous geology, pedology and land use, as well as steep topography and a rainfall regime in which summer droughts contrast with high-rainfall periods in autumn. The Ardèche catchm...

Egypt is highly exposed to flash flood hazards, particularly in Sinai Peninsula and along the Red Sea coast, causing sudden huge damages constructions losses human lives during a very short time. This paper investigates dominant characterization of morphometrical features their relationships with hydrological behaviors an important strip western coast. The study focuses on analyzing October 200...

Today, one of the major problems of flood control projects is watershed prioritizing for resource allocation and structural and non-structural practices. Due to the lack of hydrometric stations in many watersheds, is difficult determining the participation of sub catchments to create flood. So study the affective factors in watersheds through models such as multi-criteria decision analyzing sys...

Kyllmar, K. 2004. Nitrogen Leaching in Small Agricultural Catchments Modelling and monitoring for assessing state, trends and effects of counter-measures. Doctoral thesis. ISSN 1401-6249, ISBN 91-576-6761-6. Nitrogen (N) leaching from arable land to the aquatic environment is considered a serious problem. Small agricultural monitoring catchments in Sweden were used for the application and testi...

The response of twenty acid-sensitive headwater catchments in Nova Scotia to acidic deposition was investigated for the period 1850–2100 using a dynamic hydrochemical model (MAGIC: Model of Acidification of Groundwater in Catchments). To ensure robust model simulation, MAGIC was calibrated to the long-term chemical trend in annual 5 lake observations (13–20 years). Model simulations indicated t...

Nitrate input to a river is largely controlled by land use in its catchment. We compared the information carried by the isotopic signatures of nitrate in 12 Baltic rivers, in relation to the vegetation cover, land use, and fertilization of agricultural land of their catchments. We found isotope values in nitrate ranging from −2 to 14‰ for δ15N and 8 to 25‰ for δ18O. The annual variability of ri...

We conducted a 3-year study designed to examine the relationship between disturbance from military land use and stream physical and organic matter variables within 12 small (<5.5 km2) Southeastern Plains catchments at the Fort Benning Military Installation, Georgia, USA. Primary land-use categories were based on percentages of bare ground and road cover and nonforested land (grasslands, sparse ...

1. We collected adult stoneflies periodically over a 1-year period at 38 sites in two headwater catchments in the Ouachita Mountains, Arkansas, U.S.A. The 43 species collected were a subset of the Ozark-Ouachita fauna and the much larger fauna of the eastern U.S.A. We estimated 78–91% species coverage in the two catchments using jackknife extrapolation of species richness from our survey. 2. Ma...

To maintain the sustainable utilization of water resources and reduce soil erosion in the Loess Plateau, the Chinese government has adopted a number of environmental restoration strategies since 1999, including the Grain for Green Project (GFGP) and the Natural Forest Conservation Program; these large projects greatly alter the regional water cycle. Detecting runoff changes and quantitatively a...
