Water recycling also known as water reuse or water reclamation is the application of water that has already been used for human purposes and discharged as wastewater, and it typically involves the treatment of wastewater in order to make it safe for reuse. At first, water recycling was used largely to reduce the pollution associated with wastewater discharge. However, in the last decade it has been used primarily as a supplement to dwindling water supplies. Recycled water in World is most commonly used for agricultural irrigation, but it also goes to groundwater recharge, environmental uses, industrial uses, landscape irrigation, and, increasingly, as a way to mitigate the intrusion of seawater into coastal aquifers. We know that in World water demand exceeds supply in many water years, and that this is gap is likely to grow in the future due to a growing population and new pressures, climate change. Nevertheless, the majority of farmers in California still do not have access to recycled water. There is still much untapped potential to conserve water and protect ecosystems.
Published in 1904, this book ´´contains the results of a long study and numerous experiments, which had their origin in the Polar regions, were continued in more southern latitudes, and have led not only to an increase of the harvest of every kind of plant which has come under treatment, but also to a favourable change of their chemical compounds, e.g., an increase of the digestible nitrogenous matter in seeds, of the sugar in sugar-beets, proved by chemical analyses, and of the sweetness in berries, &c. The earlier ripening of some fruits is also a proved result.´´ For example, ´´during the experiments, besides the areas upon the field, there were fields of experiment and control both for carrots and peas in the garden. These four small fields being of the same size were equally watered; care was taken that every field should receive the same quantity of water. The result was that the carrots gave an increase of 125%, and the peas (after careful estimation) 75%. The results so far showed, therefore, that if electricity is applied according to the above-mentioned method, favourable results were obtained equal to an increase of 40 to 80%.´´ Electricity in Agriculture and Horticulture increases our collection of books about electroculture, this precious knowledge (www.electroculture-books.com). Even if it is an old book, we carefully reconstructed it in order there is no missing or blurred pages, poor pictures, errant marks, etc. Thank you for your support.
This book deals with a rapidly growing field aiming at producing food and energy in a sustainable way for humans and their children. It is a discipline that addresses current issues: climate change, increasing food and fuel prices, poor-nation starvation, rich-nation obesity, water pollution, soil erosion, fertility loss, pest control and biodiversity depletion. This series gathers review articles that analyze current agricultural issues and knowledge, then proposes alternative solutions.
This book presents ecological principles and applications of managing biodiversity in agriculture to decrease pesticide use and produce safe food. Major topics include ecosystem services biological pest control, conservation agriculture, drought stress, and soil biodiversity, carbon and fertilisation.
What are the challenges and action points for agricultural sustainability in Sub-Saharan Africa? This open access collection of papers offers technical analyses, policy recommendations and an overview of success stories to date. Each carefully selected paper provides valuable insights for improved policy making and defines relevant strategic priorities on Africa´s sustainable transformation process, which is in line with the international development agenda. Although agriculture remains the main source of income for Africa´s population, the sector is rain-fed subjecting it to the vagaries of weather and climate change. This volume demonstrates the rationale of developing a competitive, inclusive and sustainable agribusiness sector for Africa´s food security and structural transformation. From the impact of Bioenergy crop adoption and Drought Index Insurance to Agro-Industrialization, this volume is important reading for individual researchers, academic associations and professional bodies interested in African agricultural development.
This book discusses various climate smart agro-technologies, their technical and economic feasibility across heterogeneous agro-climatic conditions, assessing farmers´ willingness to adopt those technologies, impact of climate smart technology in agricultural production and possible policy and investment opportunities to upscale it. Containing eight chapters, the book starts with a discussion about the methodological aspects of priority setting of the farm technologies across various regions of South Asia including Eastern Indo-Gangetic plain, Western Indo-Gangetic Plain and arid regions. Using data from field based trials and expert solicitations, the book next deliberates on a list of feasible technologies, assessed by constructing climate smart Feasibility Index. Further on, there is an analysis, using stated preference method, of the behaviour of farmers in adopting climate smart technologies. Preference of women farmers has been given a special focus in this book. After discussing the method priority setting of the farm technologies, impact of climate smart technologies has been analysed using real time data. Government policies have been reviewed with the view of achieving climate smart agriculture in South Asia. The book also describes the optimization modelling framework for investment allocation and technology prioritization. The model integrates both the bio-physical and the economic optimization model to capture the agro-climatic heterogeneity within the region and the variability of technical feasibility across regions and crops. Results of this model will help policy makers to identify how much to invest, where to invest and what technologies to prioritize for investments.
