Book Description
This book introduces the concept of soil security and its five dimensions: Capability, Capital, Condition, Connectivity and Codification. These five dimensions make it possible to understand soil's role in delivering ecosystem services and to quantify soil resource by measuring, mapping, modeling and managing it. Each dimension refers to a specific aspect: contribution to global challenges (Capability), value of the soil (Capital), current state of the soil (Condition), how people are connected to the soil (Connectivity) and development of good policy (Codification). This book considers soil security as an integral part of meeting the ongoing challenge to maintain human health and secure our planet's sustainability. The concept of soil security helps to achieve the need to maintain and improve the world’s soil for the purpose of producing food, fiber and freshwater, and contributing to energy and climate sustainability. At the same time it helps to maintain biodiversity and protects ecosystem goods and services.

Book Description
Water resources in Mexico are threatened by scarcity, pollution and climate change. In two decades water consumption doubled, producing water stress in dry seasons and semi-arid and arid regions. Water stress rises due to physical and economic stress. In seven parts a multidisciplinary team analyzes hydrological processes in basins and their interaction with climate, soil and biota. Competing water use in agriculture, industry and domestic needs require savings, decontamination processes and desalination to satisfy the growing demand. Water quality affects health and ecosystems. This creates conflicts and cooperation that may be enhanced by public policy, institution building and social organization.

Book Description
El país está enfrentado un tema tan crítico como la apertura económica -tratados recién firmados como el TLC con Estados Unidos- obligan a los gremios del sector productivo a ser más competitivos si quieren continuar en el mercado. Uno de los elementos para mejorar este aspecto es la eficiencia en el uso de los recursos (fertilizantes, riegos, manejo sostenible del medio ambiente, etc.). La toma de decisiones es un paso difícil en cualquier empresa. En la empresa agropecuaria intervienen muchos elementos, componentes y variables que es necesario conocer a la hora de decidir. Como el momento de las decisiones y los resultados están alejados en el tiempo, los problemas se manifiestan cuando suele ser tarde para resolverlos. Así, para tomar buenas decisiones es fundamental una correcta información previa. Un análisis equivocado lleva siempre a un mal resultado; cuando los márgenes de ganancia de la actividad agropecuaria se reducen, el costo del error puede ser crítico. Las buenas decisiones solo pueden ser resultado de un correcto análisis de las variables y esto solo puede hacerse con buena información.

Book Description
This contributed volume compiles the latest improvements in the field of biotechnology. It focuses on topics that comprises industrial, environment, agricultural and medical related issues to technology and biological studies and exhibits the correlation between the biological world and the dependence of humans on it. The book is organized into five parts covering the role of biotechnology in industrial products, environmental remediation, agriculture and pharmacological agents. Ranging from micro-scale studies to macro, it covers a huge domain of agricultural biotechnology and focuses on important commercial crops (e.g. cacao and coffee), arbuscular mycorrhizal fungi, flow and distribution of phosphorus in agricultural soils in the Latin American region. Overall, the book portrays the importance of modern biotechnology and its role in solving the problems in modern day life. The book is a ready reference for practicing students, researchers of environmental engineering, chemical engineering, agricultural engineering, and other allied fields likewise.

Book Description
The main subject discussed in this study is the way in which the ancient Maya of Calakmul (modern Mexico), who thrived between 900 B.C. to A.D. 1000, managed their landscape in order to survive in the tropical rainforest. Their lithic technology, the hot, humid climate with a prolonged dry season, the lack of permanent surface sources of fresh water, and thin soils, considered insufficient for sustained agricultural production, are factors that were addressed successfully by the Maya in developing their complex civilization. The author's research begins with landscape, archaeological, and edaphological analyses, after which she explores the areas most advantageous to permanent habitation, suitable agricultural zones, land potential of the region and the capability of the area for supporting population. In addition, a complex agricultural channel irrigation system is explored as a critical factor for managing productive terrain for agriculture in karstic depressions (bajos). Similarly, an impressive rain harvesting system is exposed as an option to optimize hydrological resources for canalizing excessive rain during the wet season and storing water during the dry period. Finally, a reconstruction of the agricultural landscape is proposed.
