vertical farms

vertical farms:
"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?"

eles lançam a pergunta enquanto produzem uma série de atividades em diversos locais no mundo... isto, além de coletar e cadastrar projetos que tenham a intenção de responder às questões mais urgentes envolvendo sustentabilidade e cidade.
