Book Description
James O. Leckie Environmental Engineering and Science Program, Department of Civil and Environmental Engineering, Stanford University, Stanford, California 94305-4020, USA Nearly 10 years have passed since the beginning of the systematic studies of the Lerma-Chapala Basin coordinated by the Instituto Mexicano de Tecnologia del Agua. Although many public and private institutions, universities and research centers have conducted studies on the Lerma Chapala Basin over the last two decades, the need for a comprehensive summary of the findings of those studies has become increasingly obvious and important for this critical water resource. The Lerma-Chapala Basin is located in the central part of Mexico, and partly occupies five states. The watershed comprises the Lerma river and Lake Chapala. With a length of over 700 km, the tributary watershed covers 2 approximately 54,000 km . The basin accounts for more than one-third of the country's economic activity, one-fifth of all commerce and one-eighth of the nation's agricultural land. The watershed receives 3% of the country's total rainfall, less than 1 % of the runoff, and accounts for 13% of the total groundwater.

Book Description
There are four papers focusing on the special recent experience of South Africa, as it replaces former inequitable water laws with a new one tq reflect its major pOlitical reorientation, and at the same time takes this opportunity of change to bring in several other principles of modern thinking about water, with a focus on participation by stakeholders, on the river-basin as management unit, on financial principles such as "users pay" and "polluters pay;' and on the potential role of access to water in addressing social issues such as poverty and gender discrimination.

Book Description
This book contains 11 papers which cover a range of vital topics in the areas of water, agriculture, food security and ecosystems - the entire spectrum of developing and managing water in agriculture, from fully irrigated to fully rainfed lands. They are about people and society, why they decide to adopt certain practices and not others and, in particular, how water management can help poor people. They are about ecosystems - how agriculture affects ecosystems, the goods and services ecosystems provide for food security and how water can be managed to meet both food and environmental security objectives. This is the eighth book in the series.

Book Description
Between 200 and 1200 CE Central Mexico was the setting for the formation and disintegration of two states, Teotihuacan and Tula. At their peaks, both urban centers established distant ties throughout Mesoamerica. The nature of their relations has been the focus of analysis and debate for decades. In this study, Peter Jimenez uses the latest advances in world-systems analysis to study interaction networks in West Mexico from the early Classic to Post-classic period. He demonstrates how the archaeological record contains empirical evidence for the impact of global processes on local developments, in detail, in realms, and at spatial scales, which are revealed here for the first time. His examination of West Mexico's relations to the core states of Central Mexico also underscores the critical role that the semi-periphery played in overall world-system configuration and operation in ancient Mesoamerica.
