Abstract:
The objective is to analyze the socio-hydrological context of the Tijuana River Watershed to address climate change. This watershed was chosen because it was located in a semi-desert region and it is shared by Mexico and the United States, which gives to it specific characteristics. Methodology used the consultation of the Public Register of Water Rights (REPDA), data from the National Water Commission (Conagua), population projections, climate change scenarios, and academic publications, which enabled the hydrological regime, the urban growth, and the binational cooperation analysis. Results lead to understand the water transfer dependency and the cooperation among Mexico and the United States. One limitation of the study is that people’s points of view must be considered to address water scarcity in a climate change context, as well as the strategies they have implemented. It is concluded that, despite the low water availability due to the climate change context, there are binational collaboration mechanisms to supply water to urban areas of both countries. El objetivo es analizar el contexto sociohidrológico de la cuenca del río Tijuana para enfrentar el cambio climático. Se eligió esta cuenca porque se ubica en una región semidesértica y porque la comparten México y Estados Unidos, lo que le imprime características propias. La metodología se basó en la consulta del Registro Público de Derechos de Agua, en datos de la Comisión Nacional del Agua, en proyecciones de población, en escenarios ante el cambio climático y en publicaciones académicas, con lo cual se analizó el régimen hidrológico, el crecimiento urbano y la cooperación binacional. Los resultados permiten entender la dependencia del trasvase de agua y la cooperación entre México y Estados Unidos. Una limitación del estudio radica en que se debe considerar la opinión de los habitantes para enfrentar la escasez de agua en un contexto de cambio climático, así como las estrategias que han implementado. Se concluye que, a pesar de la poca disponibilidad de agua en un contexto de cambio climático, se cuenta con mecanismos de colaboración binacional para abastecer los centros urbanos de dicho recurso de ambos países.
