3CPO Posted August 28, 2006 Report Share Posted August 28, 2006 Após ter lido um pouco sobre este projecto ("The Living Tower") do atelier frances SoA Architects, aqui ficam algumas imagens e detalhes do projecto:The Problem By the year 2050, nearly 80% of the earth's population will reside in urban centers. Applying the most conservative estimates to current demographic trends, the human population will increase by about 3 billion people during the interim. An estimated 109 hectares of new land (about 20% more land than is represented by the country of Brazil) will be needed to grow enough food to feed them, if traditional farming practices continue as they are practiced today. At present, throughout the world, over 80% of the land that is suitable for raising crops is in use (sources: FAO and NASA). Historically, some 15% of that has been laid waste by poor management practices. What can be done to avoid this impending disaster? A Potential Solution: farm verticallyThe concept of indoor farming is not new, since hothouse production of tomatoes, a wide variety of herbs, and other produce has been in vogue for some time. What is new is the urgent need to scale up this technology to accommodate another 3 billion people. An entirely new approach to indoor farming must be invented, employing cutting edge technologies. The Vertical Farm must be efficient (cheap to construct and safe to operate). Vertical farms, many stories high, will be situated in the heart of the world's urban centers. If successfully implemented, they offer the promise of urban renewal, sustainable production of a safe and varied food supply (year-round crop production), and the eventual repair of ecosystems that have been sacrificed for horizontal farming. It took humans 10,000 years to learn how to grow most of the crops we now take for granted. Along the way, we despoiled most of the land we worked, often turning verdant, natural ecozones into semi-arid deserts. Over 60% of the human population now lives vertically in cities. The time has arrived for us to learn how to grow our food that way, too. If we do not, then in just another 50 years, 3 billion people will surely go hungry, and the world will be a very unpleasant place in which to live. Advantages of Vertical FarmingYear-round crop production; 1 indoor acre is equivalent to 4-6 outdoor acres or more, depending upon the crop (e.g., strawberries: 1 indoor acre = 30 outdoor acres) No weather-related crop failures due to droughts, floods, pests All VF food is grown organically: no herbicides, pesticides, or fertilizers VF virtually eliminates agricultural runoff by recycling black water VF returns farmland to nature, restoring ecosystem functions and services VF greatly reduces the incidence of many infectious diseases that are acquired at the agricultural interface VF converts black and gray water into potable water by collecting the water of evapotranspiration VF adds energy back to the grid via methane generation from composting non-edible parts of plants and animals VF dramatically reduces fossil fuel use (no tractors, plows, shipping.) VF converts abandoned urban properties into food production centers VF creates sustainable environments for urban centers VF creates new employment opportunities We cannot go to the moon, Mars, or beyond without first learning to farm indoors on earth VF may prove to be useful for integrating into refugee camps VF offers the promise of measurable economic improvement for tropical and subtropical LDCs. If this should prove to be the case, then VF may be a catalyst in helping to reduce or even reverse the population growth of LDCs as they adopt urban agriculture as a strategy for sustainable food production. VF could reduce the incidence of armed conflict over natural resources, such as water and land for agriculture Paineis: Mais informacao em:http://www.verticalfarm.com/ Abracos Tópico relacionado: http://www.arquitectura.pt/forum/f54/inhabitat-quinta-torre-5595.html Link to comment Share on other sites More sharing options...
