Vetiver grass: the ideal plant for vegetative soil and moisture conservation. Vetiver grass: the hedge against erosion. The role of vetiver grass in sustaining agricultural productivity.
This annually updated reference work reviews a range of environmental issues, such as population, human settlements, food and agriculture, forests and rangelands, wildlife, energy, oceans and coasts, the atmosphere, global systems and cycles, and policies
Together with the Olympics, world's fairs are one of the few regular international events of sufficient scale to showcase a spectrum of sights, wonders, learning opportunities, technological advances, and new (or renewed) urban districts, and to present them all to a mass audience. Meet Me at the Fair: A World's Fair Reader breaks new ground in scholarship on world's fairs by incorporating a number of short new texts that investigate world's fairs in their multiple aspects: political, urban/architectural, anthropological/ sociological, technological, commercial, popular, and representational. Contributors come from eight different countries and represent affiliations in academia, museums and libraries, professional and architectural firms, non-profit organizations, and government regulatory agencies. In taking the measure of both the material artifacts and the larger cultural production of world's fairs, the volume presents its own phantasmagoria of disciplinary perspectives, historical periods, geographical locales, media, and messages, mirroring the microcosmic form of the world's fair itself.
This handbook has been prepared to support fieldworkers and farmers in developing vegetative systems of soil and mositure conservation that will meet the requirements of small farmers in developing countries, most of whom reside in the tropics and semitropics. Experience has shown that conventional systems of earth bunds or terraces on small farms are expensive and in many cases, especially in modern times, ineffective. When applied correctly, vegetative systems of soil and mositure conservation - particulary the system of hedges of vetiver grass described in this handbook - have proved cheaper and more effective.
This book constitutes the refereed proceedings of the Third International Conference on Dynamic Data Driven Application Systems, DDDAS 2020, held in Boston, MA, USA, in October 2020. The 21 full papers and 14 short papers presented in this volume were carefully reviewed and selected from 40 submissions. They cover topics such as: digital twins; environment cognizant adaptive-planning systems; energy systems; materials systems; physics-based systems analysis; imaging methods and systems; and learning systems.
Inefficient civil service administrations are jeopardizing future development in many African countries. The reforms suggested in this paper would make these administrations more accountable, enforce the rule of law, and reward bureaucrats solely on their
