El presente artículo tiene como objetivo describir las principales características de los activos naturales de los ecosistemas mediante el desarrollo de un modelo matemático de utilización de la tierra en competencia aplicado a los ecosistemas, es decir, cómo diferentes actividades humanas compiten por el uso de los activos naturales de los ecosistemas. El modelo básico considera un desarrollo irreversible del paisaje. La tierra que se convierte y se desarrolla tiene un valor de mercado y la tasa de apreciación de la tierra en espera de desarrollo debe ser igual al costo de oportunidad de la inversión en tierras, que incluye un ajuste por la relación entre el valor de los servicios ecosistémicos y el valor de capital de la tierra desarrollada (es decir, la transformada en áreas urbanizadas o destinadas a otros usos humanos). El modelo se extiende al caso de la conversión continua del paisaje ecológico a lo largo del tiempo, considerando los costos en la pérdida de servicios ecosistémicos y de cualquier ganancia de capital de los aumentos en el valor de la tierra no convertida, es decir, aquella que no se ha modificado su estado natural original para adaptarla a un propósito o uso humano específicoReferences
