Water conservationWater conservation includes all the policies, strategies and activities to sustainably manage the natural resource of fresh water, to protect the hydrosphere, and to meet the current and future human demand (thus avoiding water scarcity). Population, household size and growth and affluence all affect how much water is used. Factors such as climate change have increased pressures on natural water resources especially in manufacturing and agricultural irrigation.
Cloud physicsCloud physics is the study of the physical processes that lead to the formation, growth and precipitation of atmospheric clouds. These aerosols are found in the troposphere, stratosphere, and mesosphere, which collectively make up the greatest part of the homosphere. Clouds consist of microscopic droplets of liquid water (warm clouds), tiny crystals of ice (cold clouds), or both (mixed phase clouds), along with microscopic particles of dust, smoke, or other matter, known as condensation nuclei.
Ice capIn glaciology, an ice cap is a mass of ice that covers less than of land area (usually covering a highland area). Larger ice masses covering more than are termed ice sheets. Ice caps are not constrained by topographical features (i.e., they will lie over the top of mountains). By contrast, ice masses of similar size that are constrained by topographical features are known as ice fields. The dome of an ice cap is usually centred on the highest point of a massif. Ice flows away from this high point (the ice divide) towards the ice cap's periphery.
MountainA mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years.
JungfrauThe Jungfrau (, ˈjʊŋˌfʁaʊ̯, "maiden, virgin"), at is one of the main summits of the Bernese Alps, located between the northern canton of Bern and the southern canton of Valais, halfway between Interlaken and Fiesch. Together with the Eiger and Mönch, the Jungfrau forms a massive wall of mountains overlooking the Bernese Oberland and the Swiss Plateau, one of the most distinctive sights of the Swiss Alps. The summit was first reached on August 3, 1811, by the Meyer brothers of Aarau and two chamois hunters from Valais.
Spring (hydrology)A spring is a natural exit point at which groundwater emerges out of the aquifer and flows onto the top of the Earth's crust (pedosphere) to become surface water. It is a component of the hydrosphere, as well as a part of the water cycle. Springs have long been important for humans as a source of fresh water, especially in arid regions which have relatively little annual rainfall. Springs are driven out onto the surface by various natural forces, such as gravity and hydrostatic pressure.
Grimsel PassThe Grimsel Pass (Grimselpass; Col du Grimsel; Passo del Grimsel) is a mountain pass in Switzerland, crossing the Bernese Alps at an elevation of . The pass connects the Haslital, the upper valley of the river Aare, with the upper valley of the Rhône. In so doing, and as the Aare is a tributary of the Rhine, the pass crosses the continental divide between the North Sea and the Mediterranean Sea. A paved road follows the pass, running from Gletsch to Meiringen. The road is normally closed between October and May, due to the high snowfall on the pass.
GrindelwaldGrindelwald is a village and municipality in the Interlaken-Oberhasli administrative district in the canton of Berne. In addition to the village of Grindelwald, the municipality also includes the settlements of Alpiglen, Burglauenen, Grund, Itramen, Mühlebach, Schwendi, Tschingelberg and Wargistal. Grindelwald village is located at above sea level. Mentioned for the first time in 1146, it has become an important tourist destination of both Switzerland and the Alps since the golden age of alpinism in the 19th century.
Comprehensive Assessment of Water Management in AgricultureThe report A Comprehensive Assessment of Water Management in Agriculture was published in 2007 by International Water Management Institute and Earthscan in an attempt to answer the question: how can water in agriculture be developed and managed to help end poverty and hunger, ensure environmentally sustainable practices, and find the right balance between food and environmental security? Compiled after consultation with more than 700 individuals, numerous organisations and networks, it was the first critica
