Book Description
The protection of water resources from deterioration in quality by pollution discharges is probably the biggest challenge in sustainable water resources management in the recent decades. In practice, most countries have adopted pollution control strategies and measures which are based on ‘end-of-pipe’ solutions: wastewater treatment plants and adjustments to the regulations, including taxes for wastewater discharges (Conventional Strategy). Although this approach involves very high costs, on many occasions, this strategy has been a complete failure. The research described in this book contribute to the development of sustainable solutions for the previously outlined problem. It was based on the validation of the Three-Step Strategic Approach concept (3-SSA), which includes: 1) prevention or minimisation of waste production; 2) treatment aimed at recovery and reuse of waste components, and 3) disposal of remaining waste with stimulation of natural self-purification of the receiving water body. The study showed overall positive effects of the 3-SSA, in comparison of Conventional Strategy, on wastewater management in the Upper Basin (389 km) of the Cauca river, the second most important river in Colombia. The Cost Benefit Analysis clearly favoured the 3-SSA, generating a major impact on the river water quality at lower cost compared to the Conventional Strategy.

Book Description
Analyzes environmental problems and policies in developing countries around the world and discusses new prospects for international cooperation and funding. Considers hard political choices, who is to blame for environmental decay, who should pay to overcome problems, and how policies should be administered. Experts from different countries offer their perspectives about the role of multilateral agencies, the North-South dimensions of environmental problems since 1972, internal and external factors that have affected Third World development, new measures and opportunities since the Rio Summit conference, and case studies of representative countries—India, China, Indonesia, Africa, Nigeria, Chile, and Mexico. A bibliography enhances this authoritative study for the use of political scientists, economists, and public administrators, for teachers, students, and professionals.

Book Description
Mexico City "...the most documented analysis of contemporary urban Mexico. Peter Ward has done it again!" Susan Eckstein, President of the Latin American Studies Association Mexico City is one of the largest and most dynamic 'megacities' of the world. The last four decades of dramatic growth have seen great economic, demographic, political and social change. Does such profound change threaten the fabric of urban life in Mexico? Peter Ward argues that Mexico City is not falling apart, not in danger of imminent implosion. Rather, its citizens and local authorities are responding positively to the major problems that confront them: economic and commercial restructuring; privatisation and deregulation; excessive centralisation; low-paid job opportunities; poor housing and infrastructure; inadequate distribution of health care facilities; poor and corrupt policing; ecological fragility threatened by pollution and earthquakes. More democratic city management systems and structures are emerging, whilst grassroots movements are making their voices heard and affecting change. This second edition of Mexico City remains the best informed guide to this most fascinating of the world's cities.
