Revitalizing Canal Irrigation Towards Improving Cost Recovery

Cost recovery from irrigation in almost all the countries presents a dismal picture. Low cost recovery coupled with declining government finances has led to the deterioration of both the quality of the built infrastructure and institutions managing and governing such infrastructure. This has created a vicious circle of low cost recovery, poor maintenance of infrastructure, inadequate and unreliable water supply, inefficient and corrupt institutions, and unwillingness of the farmers to pay. Breaking this vicious circle primarily requires identifying ways to improve availability of financial resources. Improving cost recovery from all users, including irrigators of the water, offers one of the most important avenues for raising financial resources. The present study examines some of the important issues that impinge on improving the cost recovery in canal irrigation, and assesses the feasibility of some of the efforts being made to improve cost recovery in irrigation to revitalize canal irrigation.

The book presents documentary evidence of the insufficiency of rehabilitation works to close the gap between the irrigation service and actual area irrigated of publicly funded national irrigation systems in the Philippines. It outlines a methodology for formulating a modernisation plan for national irrigation systems with focus on the mostly ungauged, medium to small canal irrigation systems. The proposed methodology adaptively modified some known modernisation concepts and techniques and integrated them in a more holistic framework in the context of changing weather patterns and river flow regimes. It includes in-depth review of rehabilitation works; system diagnosis; revalidation of design assumptions on percolation and water supply; characterisation of system management, irrigation service and demand; and drawing up of options and a vision for the modernised irrigation systems. Central to the proposed modernisation strategy is the logical coherence among the design of physical structures, system operation and water supply so that improvements of irrigation service are possible. The book discusses the development of the proposed methodology and demonstrates its utility in two case study irrigation systems.

This book is the first comprehensive effort to bring together Water, Food Security and Nutrition (FSN) in a way that goes beyond the traditional focus on irrigated agriculture. Apart from looking at the role of water and sanitation for human well-being, it proposes alternative and more locally appropriate ways to address complex water management and governance challenges from the local to global levels against a backdrop of growing uncertainties. The authors challenge mainstream supply-oriented and neo-Malthusian visions that argue for the need to increase the land area under irrigation in order to feed the world’s growing population. Instead, they argue for a reframing of the debate concerning production processes, waste, food consumption and dietary patterns whilst proposing alternative strategies to improve water and land productivity, putting the interests of marginalized and disenfranchized groups upfront. The book highlights how accessing water for FSN can be challenging for small-holders, vulnerable and marginalized women and men, and how water allocation systems and reform processes can negatively affect local people’s informal rights. The book argues for the need to improve policy coherence across water, land and food and is original in making a case for strengthening the relationship between the human rights to water and food, especially for marginalized women and men. It will be of great interest to practitioners, students and researchers working on water and food issues.

The report summarizes key results from surveys carried out on urban and peri-urban agriculture (UPA) in Tamale (Ghana) and Ouagadougou (Burkina Faso) in 2013. The aim was to provide a broad overview of the state of UPA in the study cities and a basis for future research endeavors. The randomized sampling approach used aerial photography to identify 10 sites in different categories of farm in each city. Farmers provided information on their cropping and livestock-rearing activities. There were similarities between the cities, but the differences in the expression of UPA in Tamale and Ouagadougou were more intriguing, as in farm sizes, crops grown and livestock ownership. Farmers were particularly concerned about diminishing access to land in Tamale, where sales by chiefs to private investors were accelerating. In Ouagadougou, formal reallocation of land to homeowners by the state had similarly decreased available farmland. Water availability was a universal concern, and the quality of water used for irrigation was potentially more questionable in Ouagadougou than in Tamale. The results point to the need for further work on uncontaminated, perennial water sources and soil fertility management, alongside focuses on commercialization of animal production, and the legal, political and institutional context of UPA in different West African cities.

With increasing change of traditional diets, and the emergence of new supply and marketing chains, urban food consumers in low-income countries are faced with multiple food safety challenges, among which microbial contamination and pesticides are key concerns for fruits and vegetables sold on urban markets in West Africa. Although consumers have a genuine interest in healthy food, and are willing to pay premiums, their interpretation of food quality and risks deviates from scientific health risk assessments and does not translate into recommended risk mitigation behavior. To safeguard public health, alternative measures are needed to support consumers’ risk awareness and decision making. The review looked at common and less-common options to trigger and support behavioral change, including safety labeling (certification), corporate social responsibility models, incentive systems and social marketing of safe practices, to address potential food safety risks from farming in urban and peri-urban areas. Overall, it appears that regulatory measures for risk management, including certifications, will be – for now – less effective in the West African setup due to low educational levels in view of chemical and microbial risk, diverse and often informal food chains, poor safety supporting infrastructure and weak institutional capacities for compliance monitoring.

Exposure to arsenic and the use of arsenic-contaminated groundwater in agriculture causes serious health issues. Complete or partial contamination of groundwater is reported worldwide, especially in the Eastern Gangetic Basin (EGB). This study aims to create an overall assessment of arsenic contamination in the EGB based on existing literature, demarcate the extent of the affected area, highlight the impacts on the food chain and human health, and hopes the research will help in the better planning and management of groundwater. Although several studies have evaluated arsenic contamination of groundwater in the EGB, (a) there is no proper long-term monitoring being done in affected areas; (b) there is a debate to identify the exact source and transport processes of arsenic occurrence in this region; (c) there is no comprehensive method to estimate the level of arsenic contamination in soil, water and the food chain; and (d) Arsenic contamination in Bihar and Nepal is not evaluated systematically, especially arsenic accumulation in the food chain and human health issues. Data scarcity and accessibility are the major challenges in this region. Thus, this review recommends systematic monitoring and analysis of arsenic contamination in groundwater, soils and food across the EGB.

The ‘WISE-UP to climate’ project aims to demonstrate the value of natural infrastructure as a ‘nature-based solution’ for climate change adaptation and sustainable development. Within the Tana River Basin, both natural and built infrastructure provide livelihood benefits for people. Understanding the interrelationships between the two types of infrastructure is a prerequisite for sustainable water resources development and management. This is particularly true as pressures on water resources intensify and the impacts of climate change increase. This report provides an overview of the biophysical characteristics, ecosystem services and links to livelihoods within the basin.
