Merry Kristel Dureas 11 stem D *How can human actions seriously affect water resources? Our water resources face a host of serious threats, all of which are caused primarily by human activity. They include sedimentation, pollution, climate change, deforestation, landscape changes, and urban growth. One of the most serious threats to water resources is the degradation of ecosystems, which often takes place through changes to landscapes such as the clearance of forests, the conversion of natural landscapes to farmland, the growth of cities, the building of roads, and surface mining. Each type of change to a landscape will have its own specific impact, usually directly on natural ecosystems and directly or indirectly on water resources. Although it is difficult to integrate the intricacies of ecosystems into traditional assessment and management processes a holistic ecosystem approach to water management is strongly recommended. A number of forces continue to seriously affect our natural water resources. Many of these are primarily the result of human actions and include ecosystem and landscape changes, sedimentation, pollution, over-abstraction and climate change. The removal, destruction or impairment of natural ecosystems are among the greatest causes of critical impacts on the sustainability of our natural water resources. This issue is dealt with more broadly in Chapter 5. However, it should be emphasized that the ecosystems with which we interact are directly linked to the well-being of our natural water resources. Although it is difficult to integrate the intricacies of ecosystems into traditional and more hydrologically-based water assessment and management processes, this approach is being strongly advocated in some sectors and scientific domains (e.g. Falkenmark and Rockström, 2004; Figueras et al., 2003; Bergkamp et al., 2003). The basis of this approach is the recognition that each type of landscape change will have its own specific impact, usually directly on ecosystems and directly or indirectly on water resources. The magnitude of the impacts will vary according to the setting’s conditions with a wide range of possible landscape changes. Changes that can occur to landscapes include: forest clearance, crop- or grazing lands replacing grasslands or other natural terrestrial ecosystems, urbanization (leading to changes in infiltration and runoff patterns as well to pollution), wetlands removal or reduction, new roadwork for transportation, and mining in quarries or large-scale open pits. *Ways to Coserve and Preserve the water resources: As a human we all must be responsible in using not just the water resources but also all resources in the earth because we dont know how/when these resources be gone extinct . We can start conserving and preserving it in our own simple ways.. Dispose of chemicals properly. Take used motor oil to a recycling center. Limit the amount of fertilizer used on plants. Take short showers. Shut water off while brushing teeth. Run full loads of dishes and laundry. Check for leaky faucets and have them fixed. Abandon all wells that are not needed. Keep a pitcher of drinking water in the refrigerator. Get involved in water education.
