    O MIMES – Multi-scale Integrated Model of the Earth Sytems Ecological Services é o primeiro modelo global a relacionar a dinâmica entre a tecnologia, produção e bem-estar econômico e os bens e serviços ecossistêmicos do sistema dinâmico da Terra, de forma espacializada. É um “meta-modelo” que representa uma síntese de uma simplificação dos diversos modelos globais dinâmicos existentes nas ciências naturais e sociais em um nível intermediário de complexidade. O objetivo do MIMES é simular o sistema integrado da Terra e avaliar a dinâmica e os valores dos serviços dos ecossistemas.
