BARRIAL-LUJAN, Abel Isaías et al. Amuvam model for the economic valuation of environmental assets of the Pacucha Lagoon ecosystem. Universidad y Sociedad [online]. 2022, vol.14, n.3, pp. 762-774.  Epub June 30, 2022. ISSN 2218-3620.

One of the best ways to demonstrate and convey the importance of an environmental asset is through the economic value of the or products and services generated by the ecosystem. The objective of this research was the economic valuation and prioritization of the environmental assets of the Pacucha lagoon ecosystem in the province of Andahuaylas, Perú. For this purpose, the AMUVAM model formed by AHP and income update method was used. Said methodology included applying a paired comparison survey to a conglomerate of 46 experts, and calculating the cash flow of the economic activities carried out in the area of the lagoon. In this way, the total economic value of the environmental asset of the Pacucha lagoon was determined, the sum of $ 20,793,456.81 calculated with a random consistency ratio of 0.52%. Likewise, the experts prioritized the existence value subcomponents, with biodiversity weighing 51.41%, followed by cultural heritage and visual landscape (27.07% and 21.52%) respectively. Publicizing the economic value and prioritizing the importance of environmental assets and resources would help promote their conservation and entail much more efficient intervention by the government and its stakeholders.
