The changes in water quality caused by grassing of arable land followed by the reduction in the use of fertilisers after 1989 are demonstrated on an example of two tile-drained subcatchments in spring areas in the Sumava Mountains. The original water quality monitoring was performed in the mid-1980s, at the time when the area was used as tile-drained arable land. The monitoring was renewed in 2004 under different, i.e. extensive, land use conditions.

We introduce a simple method for estimating the changes of nitrate concentrations in surface waters regarding the land use modification. Stream and drainage water nitrate concentrations in prevailingly agricultural catchments of three different scales located in the Crystalline complex of the Czech massif, Czech Republic, were included in this study. Water quality samples were collected through the years 1992-2006 at monthly and bi-monthly intervals.

Executive Summary:
"A team of Karen researchers from the Karen Environmental and Social Action
Network has undertaken this study to begin documentation of the rich
biodiversity of Khoe Kay, a bend in the Salween River that is part of their
homeland. They also want to document and expose the severe threats faced by this
stretch of the Salween, both from large dams and ongoing militarization.

This country profile describes the state of the water resources and water use, as well as the state of agricultural water management in Armenia. The aim of this report is to describe the particularities of the country and the problems met in the development of the water resources, and irrigation in particular. Irrigation trends, existing policies and legislation to water use in agriculture, possible treaties and agreements between countries as well as prospects for water management in agriculture are presented, as described in literature.

Water demand is increasing with population growth and agricultural practice leading into industrialization. Hence, the information on spatial and temporal availability of water will be helpful for the optimum utilization and sustainability of water resource. Seasonal and Spatial pattern of water availability was computed based on the water balance to facilitate better management of available water resources. The study was conducted on gergera watershed where in between -39º 30' – 39º 45' E and 13º 30' – 13º 45' N with an area extent of 8.02 km2.
