As glaciers undergo a normal process of melting during the year&#8217;s warmer months, they steadily pour vast quantities of water into rivers, sustaining humans, industry, and ecosystems. But to be able to do this, glaciers have to replenish at a similar rate during winter months when snow falls.<\/p>\n<p>More recently in the 1990s, as glaciers retreated further up the mountains in India&#8217;s cold desert mountain region of Ladakh, important meltwater started arriving later in the growing season, causing problems for water-sensitive staple crops. In response, local engineers started creating artificial glaciers that would counter water shortages by melting earlier and more reliably. One of the techniques used required the construction of a series of cascades on perennial rivers to allow ice to accumulate on the exposed surfaces. Large streams can also be diverted into smaller streams that are shaded by mountains and then freeze over. Another option is to build massive basins and fill them up in fall to slowly freeze. The Himalayan city of Leh relies on one of these.<\/p>\n<p>When the stored ice melts, they provide an important water source for farmers in the sowing months of April and May, before the rivers start fully flowing again in June. However, these approaches can be unreliable due to susceptibility to flash floods, landslides, erosion, and sedimentation. Reconstruction efforts after such problems can be enormously taxing for villagers, and often coincide with labor demands for agriculture. To address these concerns, a new technique was developed \u2014 the ice stupa, a large cone of ice that looks vaguely like Buddhist ceremonial burial mounds called stupas. Hence the name. During the wet season, a gravity-fed underground pipe brings water from high-altitude streams down the valley. There it is sprayed into a vertical fountain at night, allowing the water to refreeze over a cone-shaped base. Stupas are built next to villages and are less prone to melting due to their low surface area.<\/p>\n<p>Source: <a rel=\"noopener\" href=\"https:\/\/www.dw.com\/en\/can-artificial-glaciers-help-with-water-shortages\/a-68992899\">Deutsche Welle<\/a><\/p>\n<\/div>\n<p>The post <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\/environmental-news-en\/7-521\/\">Can artificial glaciers help with water shortages?<\/a> appeared first on <a rel=\"noopener\" href=\"https:\/\/vastuullisuusuutiset.fi\/fi\">Vastuullisuusuutiset.fi<\/a>.<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_jetpack_memberships_contains_paid_content":false,"footnotes":""},"categories":[22],"tags":[575,1655,3759,9516],"class_list":["post-130235","post","type-post","status-publish","format-standard","hentry","category-news","tag-environmental-news-en","tag-glacier","tag-melting","tag-water-shortage"],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/130235","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/comments?post=130235"}],"version-history":[{"count":0,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/posts\/130235\/revisions"}],"wp:attachment":[{"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/media?parent=130235"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/categories?post=130235"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/tietopankki.crnet.fi\/fi\/wp-json\/wp\/v2\/tags?post=130235"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
