Une \u00e9tude fond\u00e9e sur la Municipal Drinking Water Database (MDWD), portant sur les services municipaux d\u2019eau potable (pays non pr\u00e9cis\u00e9), analyse les d\u00e9penses totales, les d\u00e9penses d\u2019investissement et les recettes des syst\u00e8mes d\u2019eau. L\u2019objectif est de mieux comprendre les d\u00e9cisions financi\u00e8res des gestionnaires de r\u00e9seaux, encore peu document\u00e9es empiriquement, alors qu\u2019ils doivent concilier besoins d\u2019investissement, co\u00fbts de fonctionnement et exigences r\u00e9glementaires.<\/p>\n
L\u2019\u00e9tude s\u2019int\u00e9resse en particulier \u00e0 \u00ab l\u2019intensit\u00e9 capitalistique \u00bb des services d\u2019eau, mesur\u00e9e par le ratio entre les d\u00e9penses d\u2019investissement (capex) et les recettes des services d\u2019eau (capex ratio). Les auteurs observent une association n\u00e9gative robuste entre ce ratio et les d\u00e9penses courantes par habitant : plus la part des investissements dans les recettes augmente, plus les d\u00e9penses de fonctionnement par habitant tendent \u00e0 diminuer. En parall\u00e8le, les d\u00e9penses totales augmentent, du fait de la relation directe entre d\u00e9penses d\u2019investissement, d\u00e9penses totales et capex ratio. Plusieurs covariables ind\u00e9pendantes permettent d\u2019expliquer une partie des variations de d\u00e9penses au sein d\u2019une m\u00eame municipalit\u00e9, ind\u00e9pendamment des chocs propres \u00e0 certaines ann\u00e9es.<\/p>\n
Les r\u00e9sultats mettent en \u00e9vidence une tension structurelle entre deux objectifs de politique publique : d\u2019une part, la n\u00e9cessit\u00e9 de maintenir un niveau \u00e9lev\u00e9 et soutenu d\u2019investissement pour assurer la r\u00e9silience \u00e0 long terme des infrastructures d\u2019eau potable ; d\u2019autre part, le risque que cette dynamique d\u2019investissement continu p\u00e8se sur l\u2019accessibilit\u00e9 financi\u00e8re des services pour les usagers. L\u2019\u00e9tude souligne ainsi les arbitrages auxquels sont confront\u00e9s les gestionnaires de services municipaux d\u2019eau, dans un contexte de contraintes financi\u00e8res et r\u00e9glementaires, et apporte des \u00e9l\u00e9ments utiles pour le suivi des politiques d\u2019investissement et de tarification des services d\u2019eau, notamment sous l\u2019angle de l\u2019accessibilit\u00e9 \u00e9conomique pour les m\u00e9nages.(contenu r\u00e9sum\u00e9 en fran\u00e7ais par l’IA)\u00a0Lire la Suite<\/a><\/p>","protected":false},"excerpt":{"rendered":" Une
