Sabemos que a água é a fonte da vida. Mas também pode ser uma fonte de diversificação de portfólio. Parece estranho, mas sabemos, mas lembremo-nos: como o ouro e o petróleo, a água é uma mercadoria – e hoje em dia é bastante escassa. Portanto, como acontece com qualquer outra escassez, a escassez de água cria oportunidades de investimento.

Recursos Hídricos Globais

Cerca de 70% da superfície da Terra é coberta por água, mas 97% dela é água salgada, que é imprópria para uso humano. A água salgada não pode ser usada para beber, irrigação de plantações ou na maioria dos usos industriais. Dos 3% restantes dos recursos hídricos mundiais, apenas cerca de 1% está prontamente disponível para consumo humano.
