T I ^HE prime objective of the economic development of Mexico is the increase in agricultural land. Of the potential agricultural land in the country 83 per cent must be irrigated before it can be cultivated profitably. To increase the area under cultivation there must be an increase in irrigation and drainage works in both the arid and humid regions. There are now 3,952,000 acres of land under cultivation. This acreage can be expanded to a possible 17,290,000 acres by new and improved reclamation methods. The Mexican government is working on irrigation and drainage projects in every state. The completion of the reclamation projects in the tropical sections of Mexico will increase agricultural land in the humid regions from the present 1,235,000 acres to 5,940,000
