Comments Off on Rethinking the Water Cycle for a Water Quality Constrained World

Global water scarcity is a function of the compounding impacts of decreasing availability and declining quality. The impacts of these factors on business are complex and far reaching. Succeeding in a water quality constrained world requires the ingenuity of business to drive water strategies that go beyond conservation to reuse, recycling and stewardship.  Ecolab vice president of sustainability Emilio Tenuta will outline imperatives for achieving business resilience  amidst water scarcity.

Bowl-shaped roofs harvest rainwater and promote natural cooling in arid environments

Comments Off on Bowl-shaped roofs harvest rainwater and promote natural cooling in arid environments

Water scarcity is felt unequally throughout the world with some regions worse off than others. Iran-based BMDesign Studios addressed their home country’s arid climates with an architectural solution to water shortages called Concave Roof, a double-roof system designed to collect and store rainwater, and promote natural cooling. The Concave Roof was engineered for arid environments, where rainwater collection can be tricky due to higher than average evaporation rates and low annual precipitation. The double-roof system, which includes a domed roof beneath a bowl-shaped catchment area, is designed to “help [make] even the smallest quantities of rain [flow down] the roof and eventually coalesce into bigger drops, just right for harvesting before they evaporate,” said the architects to ArchDaily . Stacking a concave roof atop a convex roof promotes natural cooling through shade and wind movement between the two roofs.

The reservoirs are placed between building walls to help regulate indoor temperatures. With this system, the architects estimate that 28 cubic meters of water could be harvested with just 923 square meters of a concave roof surface. BMDesign Studios’ vision also goes beyond the double-roof system and includes a massing design where the buildings and courtyards are sunken to promote natural cooling. The buildings would be organized around atriums to promote circulation and community. + BMDesign Studios Via ArchDaily Images via BMDesign Studios

70% of Bolivian residents lack sufficient water amid worst drought in 25 years

Comments Off on 70% of Bolivian residents lack sufficient water amid worst drought in 25 years

The Bolivian government recently declared a state of emergency in response to the worst drought the country has experienced in 25 years. Water shortages have ignited protests, and an estimated 125,000 families have been impacted by the drought. President Evo Morales said, “We have to be prepared for the worst.” There are 339 municipalities in Bolivia, and 172 had already declared their own state of emergency. According to a Pan American Health Organization report, 70 percent of people in Bolivia don’t have enough drinking water . Most of Bolivia’s capital city has access to water only every third day, for just three hours, according to Al Jazeera. Bolivia’s Vice Ministry of Civil Defense estimates 360,000 cows and 716,605 acres used for agriculture have been hit by the drought. Related: Bolivia’s second largest lake has completely dried up The country’s water supply has dwindled, in part because in recent years Bolivian glaciers providing water for millions are melting. El Niño likely worsened the drought as well. President Morales said the country could use the crisis to “plan large investments” for Bolivia to adapt to a diminished water supply due to climate change . He also said local governments should set aside money and workers to obtain water from nearby water bodies and through drilling wells, and to transport that water to cities with the help of military forces. But some reservoirs and other water sources are nearly empty. Three dams supplying water to La Paz, home to nearly 800,000 people, are nearly dry. One of the dam’s capacities is at one percent, and the other two are at around eight percent. Al Jazeera reports that locals have protested the water shortages, and some protesters even held the country’s deputy water minister and water authorities hostage.
