Community Management of Rural Water Supply: Case Studies of Success from India (Earthscan Studies in Water Resource Management)
by Paul Hutchings Richard Franceys Stef Smits Snehalatha MekalaThe supply of reliable and safe water is a key challenge for developing countries, particularly India. Community management has long been the declared model for rural water supply and is recognised to be critical for its implementation and success. Based on 20 detailed successful case studies from across India, this book outlines future rural water supply approaches for all lower-income countries as they start to follow India on the economic growth (and subsequent service levels) transition. The case studies cover state-level wealth varying from US$2,600 to US$10,000 GDP per person and a mix of gravity flow, single village and multi-village groundwater and surface water schemes. The research reported covers 17 states and surveys of 2,400 households. Together, they provide a spread of cases directly relevant to policy-makers in lower-income economies planning to upgrade the quality and sustainability of rural water supply to meet the Sustainable Development Goals, particularly in the context of economic growth.

Community Practices for Disaster Risk Reduction in Japan (Disaster Risk Reduction)
by Rajib ShawThis book presents key lessons from community-based risk-reduction practices in Japan, a country that is often hit by disasters and that also has shown strong resilience in coping with those disasters. Japan has a strong governance system for disaster risk reduction. However, the Kobe earthquake of 1995 showed the importance of community involvement in disaster response as well as recovery. With several examples from different parts of Japan, the book elaborates on the importance of community-based risk reduction and the innovations required for sustaining some of the community approaches. The book has 13 chapters and is divided into three parts: (1) Evolution of community-based risk reduction in Japan; (2) Community-based risk-reduction issues; and (3) Case studies. The primary target groups for this book are students and researchers in the fields of environment, disaster risk reduction, and climate change studies. The book provides them with a good idea of the current research trends in the field and furnishes basic knowledge about these vital topics. Another target group comprises practitioners and policy makers, who will be able to apply the knowledge collected here to policy and decision-making.

Community Seed Production Sustainability in Rice-Wheat Farming
by Narayan Prasad Khanal Keshav Lall MaharjanThis book analyzes the sustainability of community seed production under a rice-wheat farming system from microeconomic perspectives, considering how seed producers benefit from community seed production and how those benefits continue into the future. Seed producers' performance in resource management, governance and marketing strategies indicates current benefits, whereas soil conservation and risk-management practices provide the basis for future benefits. Community seed production is a local-level seed management system owned by farmers. This system provides the institutional mechanism to supply diversified seed demands of open-pollinated varieties of food crops in a cost-effective way in rural regions. Being able to address the concerns of food insecurity, poverty, climate stress and biodiversity loss in programs and policies of development agencies, community seed production is gaining popularity among the farmers and the policy makers in developing countries. This book discusses the issues of organizational governance of the community seed producers' groups and links them with household-level benefits to understand the organizational dynamism and the probable development paths of such organizations in the future. It also highlights the necessity to institutionalize lessons learned in community seed production in the stakeholders' programs and policies. These understandings provide a basis for formulating policies for strengthening the system in developing countries. Students, researchers, policy makers and donor agencies working with CSP in the developing world will find this book useful in broadening their understanding of CSP in general and its sustainability in particular.
Cómo cambiar tu mente: Lo que la nueva ciencia de la psicodelia nos enseña sobre la conciencia, la muerte, la adicción, la depresión y la transcendencia
by Michael PollanUna brillante y valiente investigación de Michael Pollan, autor de cinco best sellers de The New York Times, sobre la revolución médica y científica en torno a las drogas psicodélicas, y la fascinante historia de sus propias experiencias psicodélicas que le cambiaron la vida. Cuando Michael Pollan se propuso investigar por qué el LSD y la psilocibina (el ingrediente activo de las setas mágicas) brindaban un enorme alivio a las personas que padecían condiciones difíciles de tratar como el TEPT (trastorno por estrés postraumático), la depresión o la adicción, no tenía la intención de escribir lo que es indudablemente su libro más personal. Pero al descubrir cómo estas notables sustancias estaban mejorando la vida no solo de los pacientes con problemas de salud mental sino también de las personas que simplemente se enfrentaban a los altibajos de la vida cotidiana, decidió explorar los límites de la mente en primera y tercera persona. Así comenzó una singular aventura entorno a la experiencia de la conciencia alterada, así como una profunda inmersión en el estudio de la neurociencia más pionera y la toma de contacto con una prodigiosa comunidad subterránea de expertos psicodélicos. En esta ejemplar investigación periodística, Pollan revisa archivos históricos y documentos científicos para separar la verdad sobre estas misteriosas drogas de los mitos, la propaganda y el pánico moral que se ha ido acumulando desde los años sesenta, cuando un puñado de personajes rebeldes catalizaron una poderosa reacción contra lo que entonces era un prometedor campo de investigación. Sugerente, polémico y deslumbrante este libro es el resultado de un viaje a una nueva, emocionante e inesperada frontera de la percepción, de nuestra comprensión de la mente, del yo y de nuestro lugar en el mundo.
Cómo evitar un desastre climático
by Bill GatesEn este libro urgente y necesario Bill Gates propone un plan amplio, práctico y comprensible para conseguir que el mundo llegue a cero emisiones de gases de efecto invernadero para así evitar una catástrofe climática. Bill Gates ha pasado una década investigando las causas y efectos del cambio climático. Con la ayuda de expertos en los campos de la física, la química, la biología, la ingeniería, las ciencias políticas y las finanzas, se ha centrado en investigar exactamente qué se debe hacer para detener la deriva del planeta hacia un desastre ambiental. En este libro, además de explicar por qué debemos esforzarnos en lograr emisiones netas cero de gases de efecto invernadero, también detalla lo que debemos hacer para lograr este objetivo tan importante. Gates nos presenta una descripción clara de los desafíos que enfrentamos. A partir de su conocimiento sobre innovación y lo que se requiere para introducir nuevas ideas en el mercado, describe las áreas en las que la tecnología ya está ayudando a reducir las emisiones, dónde y cómo la tecnología actual puede funcionar de manera más eficaz, dónde es necesario desarrollar tecnologías de punta, y quién está trabajando en estas innovaciones esenciales. Finalmente, presenta un plan concreto y práctico para lograr el objetivo de cero emisiones, sugiriendo no solo las políticas que los gobiernos deberían adoptar, sino lo que nosotros, como individuos, podemos hacer para que nuestro gobierno, nuestros empleadores y nosotros mismos nos responsabilicemos esta crucial iniciativa. Como deja claro Bill Gates, llegar a cero emisiones no será sencillo ni fácil, pero si seguimos el plan que aquí propone, es una meta que se encuentra decididamente a nuestro alcance. Para detener el calentamiento global y evitar los peores efectos del cambio climático, los humanos deben dejar de agregar gases de efecto invernadero a la atmósfera. Si nada cambia, el mundo seguirá produciendo gases de efecto invernadero, el cambio climático seguirá empeorando y el impacto en los seres humanos con toda probabilidad será catastrófico. Pero las cosas pueden cambiar. Este libro trata sobre lo que se necesitará para lograrlo y por qué estoy convencido de que podemos hacerlo. -- Bill Gates

Como Hacer Dinero Con La Impresion 3D: La Nueva Revolucion Digital
by Adidas WilsonDESCRIPCIÓN A medida que se populariza la impresión 3D, muchos han aprovechado esta industria para labrarse una fortuna y ganar en grande. Estos resultados no son ciertamente pan comido, pero por otra parte la única manera de tener éxito es salir a buscarlo, y revisar qué han hecho quienes han logrado conceptualizar esta forma de hacer dinero. Si ha estado siempre interesado en la impresión 3D y quiere hacer dinero con esta tecnología, es hora de que piense inteligentemente y venza cualquier obstáculo que se presente. Los modelos que quiera imprimir en 3D puede crearlos con un paquete CAD (diseño asistido por computador), con un escáner 3D, o con una simple cámara digital y un software de fotogrametría. Los modelos con CAD resultan con menos errores y pueden corregirse antes, pues permiten la verificación del diseño del objeto antes de imprimirlo. Hay varios proyectos y empresas esforzándose por desarrollar impresoras 3D accesibles para su uso personal en su casa. Gran parte de este trabajo ha sido movido y orientado por comunidades hágalo-usted-mismo, aficionados a hacer cosas, innovadores, con lazos adicionales al mundo académico y miembros de comunidades de hackers. La impresión tridimensional hace que sea igual de barato imprimir una pieza que miles y por esto le quita el atractivo a la economía de escala. Puede llegar a tener un impacto tan grande a nivel mundial como lo tuvo en su momento la revolución industrial y el surgimiento de las fábricas… Así como nadie podía prever en 1750 el impacto que tendría la máquina de vapor, en 1450 el que tendría la imprenta, o en 1950 lo que sería el impacto del transistor, en este momento no es posible predecir el impacto a largo plazo de la impresión 3D. Pero la tecnología está llegando, y es probable que revolucione cada uno de los campos que toque. — Tomado de “The Economist” edición líder de Febrero 10, 2011

Compact Modeling: Principles, Techniques and Applications
by Gennady GildenblatMost of the recent texts on compact modeling are limited to a particular class of semiconductor devices and do not provide comprehensive coverage of the field. Having a single comprehensive reference for the compact models of most commonly used semiconductor devices (both active and passive) represents a significant advantage for the reader. Indeed, several kinds of semiconductor devices are routinely encountered in a single IC design or in a single modeling support group. Compact Modeling includes mostly the material that after several years of IC design applications has been found both theoretically sound and practically significant. Assigning the individual chapters to the groups responsible for the definitive work on the subject assures the highest possible degree of expertise on each of the covered models.

Compact Overhead Line Design: AC and DC Lines (CIGRE Green Books)
by Rob Stephen Javier IglesiasThis Green Book provides the design engineer with an understanding of the electrical parameters and methods required in designing compact AC and DC lines. Compact AC and DC lines are becoming increasingly necessary due to the limitation of right of way access and the need to upgrade power transfer in existing, narrower line corridors. Another requirement for compact AC lines is the lower impedance permitting increased power flow.For DC power lines, increased power flow can only be realised by increasing the current through the conductors and/or increasing line voltage. In AC it can also be achieved by bundle expansion and phase compaction due to the variation of impedance. The effect of compaction on AC and DC lines is not identical as with the constraints. The Green Book covers the theory relating to the constraints such as corona, audible noise, insulation coordination, electric and magnetic fields and others for both AC and DC lines.In addition to the theory, the Green Book includes actual calculations of electric parameters for different pole (DC) and phase (AC) configurations. Standards applied by various countries are tabulated for easy comparison of practices internationally. Case studies on line compaction designs for both AC and DC are described with relation to pole compaction, pole rearrangement and phase configuration. Voltage upgrading is also treated in this book, and some case studies for both AC and DC are considered.
