Territorial, transformation, movements and changes in ecosystem sistem services, Armenia, Colombia

Abstract

Urban growth has an impact in forested coverages on agricultural territories and the provision of ecosystem services. It was proposed to analyze in Armenia the relations between urban growth, the rural and urban component of the population and the supply of ecosystem services of provision (coffee, banana and meat). The work was oriented in: (i) the analysis of the 1938–2005 demographic trend, (ii) the dynamics of expansion between the municipal seat and the agricultural territory (1998–2015), and, (iii) the supply of ecosystem services that provide to food security. In 1998, the municipality experienced territorial fragmentation, which affected the supply of services. In 2015, a territorial homogenization is evident, in the upper zone the urbanization processes are concentrated in the pastures adjacent to the urban perimeter, while the middlen and lower zones are located coffee and banana plantations. The dynamics of urban growth in Armenia created pressure in the forests that declined in 1989 ha, on agricultural coverage and, in consequence, is considered a threat to the ecosystem services offered by these coverages in the territory that affects the purpose of achieving productive and sustainable rural development.
