From a river-basin perspective, wastewater irrigation is an important form of water and nutrient reuse; however, there are important water quality, environmental, and public health considerations. This report explores the advantages and risks of urban wastewater reuse for crop production in the water-short Guanajuato river-basin in west-central Mexico, and then by a selective literature review demonstrates how common this practice is worldwide.
Regions where community forest enterprises dominate the landscape have low to non-existent deforestation, sustainable forest management, enhancement of carbon stocks, forest conservation and substantial generation of sustainable livelihoods. Corruption and deforestation are also associated with some Mexican forest communities, but these regions have created a sector with hundreds of well-managed community forests that contribute to the mitigation of, and adaptation to, climate change. Some 60–70% of Mexican forests are now owned by communities.
This article argues that policy making is an interactive and ongoing process that transcends the spatio-temporal boundaries drawn by a linear, rational or instrumental model of policy. We construct this argument by analysing the making of the Irrigation Management Transfer (IMT) policy in Mexico in the early 1990s, focusing on different episodes of its re-emergence, standardisation, and acceleration. During this period a standardised policy package was developed, consisting of a set of specific policy technologies to effect the transfer to Water Users' Associations (WUAs).
