The South Lake Tahoe Monitoring Project, a volunteer water quality monitoring effort coordinated by the Sierra Nevada Alliance, tested pollution levels in creeks and rivers. 2008 was the first field season for the group of trained citizen-monitors. Volunteers checked for polluted water in local creeks and rivers by collecting data which evaluates the health of water bodies in the Upper...
The Sierra Nevada Alliance developed a set of surveys, conducted over six weeks’ time in December 2004 and January 2005, to assess the capacity and organisational needs of watershed groups in the Sierra. The surveys were designed to assess groups in three different categories, Alliance members, Sierra land use groups and Sierra watershed organisations. This report focuses on the Sierra...
The report shows that climate variability can have a real and lasting impact on how people manage their water resources and that the dynamics of changing patterns of water availability have knock-on effects that reach far beyond just water. Traditional cultural norms, agricultural methods and wider livelihood approaches are also affected.
Despite the challenges faced, communities have...
Much of El Salvador's crop production is in mountainous areas with gradients over 15%. The main crops are shade-grown coffee, sugar cane, citrus and other fruit trees, and staples for local consumption, including maize, beans, rice, and sorghum. The latter are produced on small-scale subsistence farms in mountainous zones (0.3–2 ha per farmer) characterised by intensive use...
Mountains play a crucial role in the supply of freshwater to humankind, in highland and lowland areas alike. Increasing demand urgently requires careful management of mountain water resources in order to mitigate growing water crises and conflicts. Monitored river flow was analyzed for three selected catchments (Timau, Burguret, and Likii) on the slopes of Mount Kenya from 1960 to 2004....
In the past decade, water shortage on the western and northern slopes of Mount Kenya and particularly in the adjoining lowland areas has reached a severity not experienced before. Rapid population growth and rising demand for irrigation are increasing the pressure on water resources, as can be demonstrated by an inventory of water abstractions from the Naro Moru River. A total of 98...
