Download or read book Management of Irrigation and Water Supply Under Climatic Extremes written by M. Dinesh Kumar and published by Springer Nature. This book was released on 2021-03-20 with total page 371 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a theoretical basis for the argument that available research that analyzes the impacts of climate on hydrology, water resources, and water systems, without factoring in the effect of climate variability, are inadequate and often misleading. Also, the book empirically shows that the impacts of climate variability on hydrology and water resources, and irrigation, water supply & sanitation systems are far more pronounced than the likely impacts of future change in climate. The book discusses technological, institutional and policy alternatives for reducing these impacts on various competitive use sectors, especially, irrigation, and water supply and sanitation through case studies of river basins in different hydrological setting. To set the context, the volume first presents the long term trends in precipitation and temperature in different regions of India, and compares them against inter-annual, inter-seasonal and intra-day variations in climatic parameters, to show how their differential impacts on water resources.

Download or read book Pathways from irrigation to prosperity nutrition and resilience The case of smallholder irrigation in Mali written by Nkonya, Ephraim M. and published by Intl Food Policy Res Inst. This book was released on 2022-07-02 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Irrigation is increasingly promoted in Africa south of the Sahara, but the benefit streams of small-scale irrigation in Mali remain largely unknown. This study collected detailed quantitative data of irrigators and non-irrigators in two regions of Mali: Mopti, which is in the Sahelian zone, and Sikasso, the southernmost region of the country, which receives more rainfall. Econometric results show that the irrigation suitability, female household headship, proximity to markets and market participation increase the propensity to irrigate. The results suggest that small-scale irrigation investments have the potential to benefit women farmers directly. We used Two-Stage Weighted treatment effects multivariate regression to identify the impact of irrigation on selected outcomes. The impact assessment results show that crop income and diversification, market participation, employment, and dietary quality were substantially higher in irrigated farms compared to non-irrigated farms. Likewise, irrigating households had higher food security and higher dietary diversity. The results show that irrigation is a key entry point for combatting climate variability and change. However, the low adoption levels of improved water-lifting technologies are a major challenge. Limited promotion of solar and motorized pumps has contributed to the low adoption of these improved water-lifting technologies. A less profitable option, lifting water with a rope-and-bucket system, remains the most common water-lifting technology in the study areas. We find that investing in effective advisory services that target agricultural water management could increase uptake of more profitable irrigation technologies.

Download or read book Development Engineering written by William Kisaalita and published by Cambridge Scholars Publishing. This book was released on 2020-08-28 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book details the development and evaluation of technological interventions designed to improve human and economic development within complex, low-resource settings, showing that a solution becomes an innovation when it reaches widespread use. The book shortens the time-gap between development and up-take of the intervention, especially for student solution-developers or innovators who are new to the cultural and geopolitical settings of the problem-source country or region. Technological interventions in development are sustainable if they meet a real need, are affordable by the users, fit within the cultural context and are ergonomically appropriate. Many interventions have failed because of inattentiveness to one or more of these factors. Each of the book’s points is backed up with scholarly research work, confidently guiding solution-developers confronted with issues such as acquiring intellectual property protections, among many others.

The report closes by drawing some key lessons and offering nine recommendations for actions by African governments and the private sector.
Download or read book Can market based approaches to technology development and dissemination benefit women smallholder farmers written by Njuki, Jemimah and published by Intl Food Policy Res Inst. This book was released on 2014-07-11 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rural household economies dependent on rainfed agriculture are increasingly turning to irrigation technology solutions to reduce the effects of weather variability and guard against inconsistent and low crop output. Organizations are increasingly using market-based approaches to disseminate technologies to smallholder farmers, and, although women are among their targeted group, little is known of the extent to which these approaches are reaching and benefiting women. There is also little evidence on the implications of womens use and control of irrigation technologies for outcomes, including crop choice and income management. This paper reports findings from a qualitative study undertaken in Tanzania and Kenya to examine womens access to and ownership of KickStart pumps and the implications for their ability to make major decisions on crop choices and use of income from irrigated crops. Results from sales-monitoring data show that women purchase less than 10 percent of the pumps and men continue to make most of the major decisions on crop choices and income use. These findings vary by type of crop, with men making major decisions on high-income crops such as tomatoes and women having relatively more autonomy on crops such as leafy vegetables. The study concludes that market-based approaches on their own cannot guarantee access to and ownership of technologies, and businesses need to take specific measures toward the goal of reaching and benefiting women.
Download or read book Sustainable Enterprise written by Mark Peterson and published by SAGE Publications. This book was released on 2012-10-08 with total page 561 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is appropriate for the following courses: Sustainable Enterprise Sustainable Business Practices Sustainability Marketing Society Social Marketing Sustainable Enterprise: A Macromarketing Approach goes beyond the internal firm strategies of micromarketing and the "four Ps" to take a broader perspective focused on the interconnectedness of markets, marketing, and society. In a globalized society concerned with social and environmental sustainability, this book encourages students to think critically about the opportunities and limitations of marketing, as well as its positive and potentially negative effects. Through the presentation of key research findings and actual company cases, Peterson engages students with questions such as: How do firms use sustainability concepts to navigate their firms in global business today? Why do markets change? How can firms conduct business profitably with the environment in mind? How can firms conduct business profitably with poor consumers in mind? Based on the premise that firms using holistic marketing strategies are better able to assess risks and identify opportunities, this text explains how firms can approach the marketplace to benefit the company, key stakeholders, and society at large. The result is a one-of-a-kind book that successfully explores macromarketing for sustainable enterprise.
