Demanda, disponibilidad de pago y costo de oportunidad hídrica en la Cuenca Tapalpa, Jalisco José René Valdez Lazalde Cristopher López Paniagua Héctor Manuel De los Santos Posadas Manuel de Jesús González Guillén Agrociencias uso del suelo Costo de oportunidad disponibilidad a pagar valor del uso del agua mercado de servicios ambientales Para conocer la factibilidad de la creación de un mercado de servicios ambientales hidrológicos,se requiere contar con información sobre la oferta y demanda hídrica del lugar. Este estudio pretendeaportar información sobre el último aspecto, al estimar la demanda hídrica en la cuenca de Tapalpa,Jalisco, México, en cuya superficie de 21 000 ha, la mitad es forestal. Adicionalmente, se estimó ladisponibilidad a pagar (DAP) por el recurso hídrico (RH), además de un análisis del costo de oportunidaddel uso del suelo para producción de agua. El análisis indicó que el RH utilizado asciende a23 171 885 m3/año. El 93% de éste se utiliza en el sector agrícola, principalmente en la producciónde hortalizas y cultivos básicos. La DAP calculada por el RH es mayor en el sector servicios (76,7%de los casos dijeron estar dispuestos), en comparación con los otros sectores encuestados. Sinembargo, la mayor participación monetaria en la DAP total estuvo dada por el sector doméstico, con46,5% del total, con $3 064 301 pesos al año. Adicionalmente se determinó que la escolaridad tieneuna relación directa con la DAP por RH, mientras que la edad presentó una relación inversa. El valorestimado de la DAP total fue menor que el costo de oportunidad para conservar la superficie boscosade la cuenca, presentando un déficit anual de $27 201 313 pesos, y sólo cubre el 10% de dicho costode oportunidad. Al agregar el costo asociado a la recuperación de la superficie forestal actualmenteen otro uso (áreas en conflicto), el déficit anual se incrementaría a $45 130 988 pesos y la DAP sereduce a sólo 6% del costo de oportunidad total 2007 artículo científico 1405-0471 https://www.redalyc.org/articulo.oa?id=61713102 es http://www.redalyc.org/revista.oa?id=617 Madera y Bosques application/pdf Instituto de Ecología, A.C.
