Les enjeux de l’approvisionnement en eau au Mexique

In 2004, the population of Mexico exceeded 103 million people. The current level of demographic growth in the country has its origin in the fast growth rate of the population, registered until the 70s of last century. Although the growth rate has been falling since then, the population continued t...
