Available in PDF, EPUB and Kindle. Book excerpt: The System of Rice Intensification (SRI) involves the adoption of certain changes in management practices for rice cultivation that create a better growing environment for rice crops. The use of intermittent irrigation with alternate wet and dry intervals (AWD) and single transplanting of the younger seedlings in wider spacing areas are regarded as the key factors in SRI for better crop growth and productivity. Field experiments were conducted in Chiba, Japan during the two consecutive rice growing seasons (May-September) of 2008-09 to observe the effects of SRI components on rice crop performance, field environment, water savings, and water-wise rice production. The effects of the irrigation method, age of seedlings and spacing were evaluated in the 2008 rice season with eight treatment combinations in a split-split plot design (S-SPD). AWDI at 10 day intervals and continuous flooding throughout the cropping season were the two main plot factors while the effects of seedling age (14 and 21 days) and plant spacing (30x30 cm2 and 30x18 cm2) were evaluated as sub and sub-sub plot factors, respectively. The experimental results revealed that the SRI management with the proposed AWDI can save a significant amount of irrigation water (29%) without reduced grain yield (7.41t/h compared with 7.37t/ha from normal planting with ordinary water management). Water productivity was also observed to be significantly higher in all combinations of practices in AWDI plots: 1.74 g/liter with SRI management and AWDI as compared to 1.23 g/liter in normal planting with ordinary water management. In addition, the research outcomes showed a role of AWDI in minimizing pest and disease incidence, shortening the rice crop cycle and also improving the plant stand until harvest. Synergistic effects of younger seedlings and wider spacing were seen in tillering ability, panicle length and a number of filled grains that ultimately led to higher productivity with better grain quality. Field experiments with the complete sets of SRI practices were carried out in Randomized Complete Block Design (RCBD) during the 2009 rice growing season in the same field. SRI (with 8 day old seedlings) and conventional (with 22 day old seedlings) practices were the first factor (cultivation method), while organic and inorganic managements were evaluated as the second factor (management method) in the field experiments. The highest yield was observed through the conventional method with inorganic management (6.84t/h) that was on par with the organic SRI (6.59t/h) followed by organic conventional (6.48t/h). It was recorded as 5.92t/h in inorganic SRI management. Overall, the effects of SRI components were positive and significant on a per plant basis; however, they did not differ significantly in terms of grain yield per unit area. The development of healthy and vigorous roots, increased stem diameter, greater productive leaf area, longer panicles, greater number of filled grains, development of plants tolerant to insect-pest and disease, and reduced plant lodging percentage were some notable achievements with SRI management. Water savings and water-wise rice production are other important issues that are likely to draw the attention of rice researchers and farm communities to adopt SRI under scarce water conditions. However, comparatively better grain yields with conventional management methods underscore a need for further investigations in defining an appropriate combination of practices for SRI management, considering local soil properties, prevailing climate and critical watering stages in rice crop management.

This book was released on 2015-12-12 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: The System of Rice Intensification, known as SRI, is a management strategy for crop improvement. Its ideas, insights and practices are based on scientifically validated knowledge for increasing the production of not only irrigated rice but of other crops as well. SRI represents a paradigm shift in agricultural thinking and practice toward agroecological farming that can be used by even the poorest smallholding farmers in ecologically fragile regions of the world to achieve food security in the face of the climate-change challenges ahead. When the author Norman Uphoff first learned about SRI in Madagascar in 1993, this production system which offered higher yields with reduced inputs seemed implausible to him. But the professor put aside his skepticism after seeing farmers who had been getting rice yields of just two tons per hectare produce four times more rice-for three years in a row-on their very poor soils, not changing their varieties or relying on agrochemical inputs, and using less water. Now, he's helping to disseminate this dramatically effective methodology with this accessible, easy-to-use sourcebook. It offers explanations, research references, vivid pictures, and concrete examples of the award-winning SRI methodology to anyone interested in the development of practicable sustainable food systems.

Download or read book Sustainable Intensification written by Jules N. Pretty and published by Routledge. This book was released on 2012-06-25 with total page 292 pages. Available in PDF, EPUB and Kindle. Book excerpt: Continued population growth, rapidly changing consumption patterns and the impacts of climate change and environmental degradation are driving limited resources of food, energy, water and materials towards critical thresholds worldwide. These pressures are likely to be substantial across Africa, where countries will have to find innovative ways to boost crop and livestock production to avoid becoming more reliant on imports and food aid. Sustainable agricultural intensification - producing more output from the same area of land while reducing the negative environmental impacts - represents a solution for millions of African farmers. This volume presents the lessons learned from 40 sustainable agricultural intensification programmes in 20 countries across Africa, commissioned as part of the UK Government's Foresight project. Through detailed case studies, the authors of each chapter examine how to develop productive and sustainable agricultural systems and how to scale up these systems to reach many more millions of people in the future. Themes covered include crop improvements, agroforestry and soil conservation, conservation agriculture, integrated pest management, horticulture, livestock and fodder crops, aquaculture, and novel policies and partnerships.

Available in PDF, EPUB and Kindle. Book excerpt: Given the central role of the food and agriculture system in driving so many of the connected ecological, social and economic threats and challenges we currently face, Rethinking Food and Agriculture reviews, reassesses and reimagines the current food and agriculture system and the narrow paradigm in which it operates. Rethinking Food and Agriculture explores and uncovers some of the key historical, ethical, economic, social, cultural, political, and structural drivers and root causes of unsustainability, degradation of the agricultural environment, destruction of nature, short-comings in science and knowledge systems, inequality, hunger and food insecurity, and disharmony. It reviews efforts towards ‘sustainable development’, and reassesses whether these efforts have been implemented with adequate responsibility, acceptable societal and environmental costs and optimal engagement to secure sustainability, equity and justice. The book highlights the many ways that farmers and their communities, civil society groups, social movements, development experts, scientists and others have been raising awareness of these issues, implementing solutions and forging ‘new ways forward’, for example towards paradigms of agriculture, natural resource management and human nutrition which are more sustainable and just. Rethinking Food and Agriculture proposes ways to move beyond the current limited view of agro-ecological sustainability towards overall sustainability of the food and agriculture system based on the principle of ‘inclusive responsibility’. Inclusive responsibility encourages ecosystem sustainability based on agro-ecological and planetary limits to sustainable resource use for production and livelihoods. Inclusive responsibility also places importance on quality of life, pluralism, equity and justice for all and emphasises the health, well-being, sovereignty, dignity and rights of producers, consumers and other stakeholders, as well as of nonhuman animals and the natural world. Explores some of the key drivers and root causes of unsustainability , degradation of the agricultural environment and destruction of nature Highlights the many ways that different stakeholders have been forging 'new ways forward' towards alternative paradigms of agriculture, human nutrition and political economy, which are more sustainable and just Proposes ways to move beyong the current unsustainable exploitation of natural resources towards agroecological sustainability and overall sustainability of the food and agriculture system based on 'inclusive responsibility'

Download or read book Climate Change and Agricultural Development written by Udaya Sekhar Nagothu and published by Routledge. This book was released on 2016-07-15 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two of the greatest current challenges are climate change (and variability) and food security. Feeding nine billion people by 2050 will require major efforts aimed at climate change adaptation and mitigation. One approach to agriculture has recently been captured by the widely adopted term of "Climate Smart Agriculture" (CSA). This book not only explains what this entails, but also presents practical on-the-ground studies of practices and innovations in agriculture across a broader spectrum, including agroecology and conservation agriculture, in less developed countries. It is shown that CSA is not a completely new science and a number of its recommended technologies have been used for some time by local farmers all over the world. What is relevant and new is ‘the approach’ to exploit their adaptation and mitigation potential. However, a major limitation is the lack of evidence-based knowledge that is necessary for policy makers to prepare strategies for adaptation and mitigation. This book assembles knowledge of CSA, agroecology and conservation agriculture, and perspectives from different regions of the world, to build resilient food systems. The first part analyzes the concept, opportunities and challenges, and provides a global perspective, drawing particularly on studies from Africa and Asia. The second part of the book showcases results from various studies linked to soil, water and crop management measures from an ongoing program in India as well as experiences from other regions. The third section assesses the needs for an enabling policy environment, mainstreaming gender and sime final recommendations for up-scaling and/or out-scaling innovations.

Book excerpt: There is hope for us yet: “Stevenson’s engaging commentary has the ability to restore your faith in human ingenuity in the face of adversity.” —Geographical magazine Our systems are failing. Old models—for education, healthcare and government, food production, energy supply—are creaking under the weight of modern challenges. As the world’s population heads towards 10 billion, it’s clear we need new approaches. In We Do Things Differently, historian and futurologist Mark Stevenson sets out to find them, across four continents. From Brazilian favelas to high-tech Boston, from rural India to a shed inventor in England’s home counties, Mark Stevenson travels the world to find the advance guard reimagining our future. At each stop, he meets innovators who have already succeeded in challenging the status quo, pioneering new ways to make our world more sustainable, equitable, and humane. Populated by extraordinary characters—including Detroit citizens who created new jobs and promoted healthy eating by building greenhouses; an Austrian mayor who built a new biomass plant using the by-product of a local flooring company; and an Indian doctor who crowdsourced his research and published his findings online—We Do Things Differently paints a riveting picture of what can be done to address the world’s most pressing dilemmas, offering a much-needed dose of down-to-earth optimism. It is a window on (and a roadmap to) a different and better future. “Stevenson writes with enormous warmth and humor.” —Cory Doctorow
