Los deltas metropolitanos emergentes en el contexto del cambio global: Ejemplos internacionales y análisis del caso del Delta del Paraná

Historically, both coastal areas and deltas have been attractive places for human settlements due to their natural wealth and strategic location. These qualities have made them suitable sites for the development of productive, industrial and commercial activities. Precisely, it is estimated that half of the world's population is located within a radius of 200 km from the coast, a figure that would double by 2025.

The increase in the demand for land for residential and productive purposes causes a change in use that impacts the natural territory at different scales. Likewise, the natural dynamics of coastal zones and deltas, and those related to climate change, generate effects on the occupied territories, increasing their vulnerability to extreme hydrological events. Thus, these areas reach a double complexity, fundamentally derived from the coexistence of emergent processes, both natural and anthropic, in a context of continuous change and uncertainty regarding the future.

It is necessary from the planning field to consider the complex reality of these areas in relation to future uncertainty, through the development and implementation of adaptive and participatory planning processes that allow these systems to increase their resilience.

The presentation will delve into the analysis of emerging processes in metropolitan deltas, presenting examples from the international as well as the national sphere. Likewise, an adaptive and participatory planning tool applied in the Lower Paraná Delta will be presented.
