This sourcebook provides an overview of current and upcoming information and communications technology (ICT) for agricultural innovation, and discusses their potential to improve productivity, services institutions and value chains. It aims to provide both technical and policy guidance to development professionals and decision makers, and focuses on how ICT can support poor smallholder farmers including female farmers.
The guide includes fourteen modules on various aspects of ICTs in agriculture, including how to use the technologies to boost livestock, crop and fishery production; increase smallholder farmers' access to financial services; and improve rural governance. Each module provides information about current trends in ICT use, identifies challenges and lessons learned, notes how technologies have been used to achieve specific goals, and offers examples of successes or failures. The report describes the contributions these technologies can make, provides guidance on how to design and implement ICTs and on how to evaluate them.

This report gives an overview of education challenges facing the developing world and discusses the technologies available to address them. It aims to provide guidance to decision-makers designing, implementing or investing in education initiatives.
The report focuses on the potential of recent information and communications technology (ICT) such as mobile phone and laptops, and examines conditions that can influence whether technology interventions are successful. It also focuses on the world's poorest countries.
The authors put forward seven principles for effective use of technology in education, which include a focus on identifying the problem before introducing a technology to address it, and considering whether the design and implementation of the technology will allow it to last over time. The report concludes that ICTs can bring quality learning to some of the world's poorest and hard-to-reach communities.

This report presents findings from the first randomised evaluation of a cash transfer programme delivered using mobile phones. The study investigated the effect of mobile phone technology on monthly cash transfers to households in Niger that were affected by a severe drought.
Villages that received cash in this way, known as 'zap', saw benefits such as reduced costs of receiving cash, more diverse purchases and diets, and more types of crops. This, suggest the authors, is down to the zap mechanism encouraging different decision-making in the household, as well as due to lower costs and greater privacy.
They conclude that mobile transfers are a cost-effective way of transferring cash to remote rural populations, especially those with limited road and financial infrastructure, but caution that more research is needed on broader effects on the welfare of these populations.

In this review article, published after the Fukushima accident, medical scientists examine published information on the short- and long-term health risks of exposure to ionising radiation. The article describes two previous nuclear accidents — at Three Mile Island in the USA, and Chernobyl in Ukraine — and explains the types and doses of radiation that can damage biological systems. It discusses the mechanisms behind exposure, and radiation-induced illness and injury, including long-term cancer risks. The authors also review measures that can be taken to reduce the effects of radiation exposure, including potassium iodide tablets used in the aftermath of Chernobyl. The article stresses that clear communication on radiation exposure levels and health risks is a key component of the response to a nuclear incident.

This policy brief, from Harvard University, explores research and development (R&D), cost and performance issues that the nuclear power sector needs to consider if the industry is to meet the growing demand for carbon-free energy. Based on surveys it offers estimates of the costs and performance of this research, and potential benefits that could be gained over the next 20 years.
A key finding is that current levels of public investment in nuclear power technologies will not lead to a major reduction of the cost of nuclear plants by 2030. Instead, many of today’s R&D programmes are focused on capabilities such as extending uranium resources or improving waste management and safety. The authors acknowledge that the Fukushima accident has highlighted the need for better preparedness and has undermined confidence in nuclear energy. The report concludes that development of nuclear power should address issues aside from R&D such as getting public acceptance and support from governments.

This paper, published by the UK-based Institute of Development Studies, examines how disaster risks associated with climate change might impact electricity generation and energy planning — which is an emerging research and development agenda. The authors argue that energy researchers and policymakers have overlooked how changing disaster risks could affect electrical power production.
The report assesses the vulnerability of nuclear power as well as several other options for energy generation — including oil, natural gas, hydropower and bioenergy — and identifies the implications for energy policy and planning. It lists recommendations as to how policymakers could take into account the link between disaster risk management and low-carbon development to improve the capacity of developing countries to build resilience. Suggestions include completing environmental impact assessments when siting new power plants, establishing better links between energy, climate, and disaster policymakers, and planning climate change adaption strategies for electricity production.

This safety guide, published by the International Atomic Energy Agency (IAEA), is designed to help countries prepare plans to improve their capacity to respond to nuclear or radiological emergencies whether as a result of an accident or malicious use of nuclear material. The guide can also be used to meet IAEA's safety requirements.
It outlines generic and operational criteria, according to specific radiation doses, to help policymakers decide between different courses of action to protect the public, emergency workers and the environment. It includes guidelines for assessing food and water contamination, and subsequent remediation measures, as well as on how to set safety perimeters around an incident depending on initial observations at the scene. The guide also outlines lessons learned from past experiences.

This report, published by the International Atomic Energy Agency (IAEA), details a survey of all significant nuclear-related developments that took place in 2010 worldwide, and outlines how each of the developments has affected the work of the IAEA.
It provides updates on the status and trends in nuclear power, including plants that are under construction, and offers up-to-date details of global uranium resources, safety and emergency preparedness guidelines, and applications of nuclear technology in areas such as cancer treatment. Changes in nuclear law, proposals for nuclear waste management and the status of decommissioned sites are also discussed. The report concludes that countries, international organisations and civil society must work together and respond to future challenges collectively if nuclear energy is to benefit development.

This review article, published before the accident at Fukushima, discusses the immediate and long-term prospects of nuclear power development to meet future carbon-free energy needs. It explores opportunities and constraints of generating a nuclear power 'renaissance', and puts forward six possible options for building a sustainable nuclear energy industry.
The authors say that nuclear technology is at a crossroads, and if it is to move forward a two-stage strategy is needed. The first stage must involve developing or extending the life of the world’s existing nuclear plants over the next two years, to improve their efficiency and reliability. In the second stage, after 2030, the industry should look to build new nuclear power stations with large-scale fuel cycles that may include fuel reprocessing. They highlight measures that, if taken now, could make nuclear a viable energy option in the future.

This report, from the US-based Worldwatch Institute, provides qualitative and quantitative information about nuclear power plants in operation; under construction; and those being planned worldwide. It also includes an overview of reactions to the nuclear accident in Fukushima, Japan.
The authors analyse the economic performance of past and present nuclear projects, and compare them with other leading renewable energy sources. A country by country rundown of nuclear power projects can be found in the annex of the report.
Key findings suggest that nuclear power can no longer keep pace with the development of other renewable power sources. The report states that the nuclear industry had been in decline even before the Fukushima disaster because not enough new reactors are becoming operational, while existing reactors are aging rapidly. The authors believe that the disaster at Fukushima is likely to accelerate this downward trend.

This guide, published by the International Atomic Energy Agency, offers practical advice for policymakers, managers and advisers in countries that are setting up their first nuclear power plant, or those restarting an inactive nuclear programme. It provides information about the activities, responsibilities and desired attributes of those running nuclear plants, whether private companies or the state. It also describes the experience of countries that have built and operated nuclear power plants, and outlines how the owner and operator should interact with national authorities, nuclear and environmental regulatory bodies, the national grid, waste management, and emergency planning and response organisations. The report also provides examples of contracts that can be used in the process of setting up a power plant.

This report, from the Australian Centre for International Agricultural Research (ACIAR), highlights the results of research into what drives and inhibits the uptake of new crop-livestock farming techniques by small-scale cattle farms in Asian countries. The authors describe five farming systems in China, Indonesia and Vietnam that have attempted to increase beef production and profitability by integrating new farming knowledge and technology with help from ACIAR. Using these case studies, the authors draw out lessons learned for future initiatives. Key findings include the importance of partnering with local people who have a good understanding of the farming system, and having a realistic expectation of the scale of improvements that can be made with new technologies.

This report investigates how the next generation of information and communication technologies (ICTs) — such as open mapping and open source crowdsourcing platforms — can empower vulnerable communities and build local capacity.
It is based on an investigation of how initiatives such as Map Kibera, an online community information source based in Kenya, contribute to creating shared information resources. The empirical data also provide insights into the hurdles and opportunities facing marginalised communities using these innovative communication tools. The report also presents results from interviews of leaders of ICT initiatives deployed to support post-reconstruction efforts in Haiti.
It outlines the challenges of using ICT for development, including the need to balance short-term individual benefits with longer-term agendas and the responsibility of those in charge to build trusting relationships to diffuse tensions emerging from free information sharing.
The study highlights the role of open-source social entrepreneurs as a new development actor, and the opportunities for collaboration between development and technology practitioners. The report suggests a follow-up research agenda to build upon this initial investigation.

This report aims to give practical recommendations on the design of Climate Innovation Centres (CICs), which seek to tackle barriers to the transfer, development and deployment of climate technologies in developing countries. It was commissioned by infoDev in collaboration with the UK Department for International Development and the UN Industrial Development Organization.
The report argues that developing countries lag in their capacity to transfer, develop and deploy innovative climate technologies — making them passive recipients of technologies developed elsewhere that are not suited to local conditions.
It highlights gaps and barriers to climate technology innovation based on a survey of 62 developing countries, and after screening more than 550 organisations to identify 67 as potential CICs. To be successful, it says, CICs will need to perform several functions such as committing their own capital to climate technology innovations or finding new ways to attract investors; coordinating research and development; and performing technology needs assessments.

This follow-up paper, from the Journal of Nanotechnology Online, provides an in-depth look at the way poor countries engage with nanotechnology. It analyses why some developing nations are ahead of others in nanotechnology progress, and the challenges some less-developed countries face in shoring up nanotechnology capacity. It also investigates nanotechnology patent activity and assesses country participation in nanotechnology policy dialogues – for instance, China is a frontrunner in filing nanotech patents yet it is absent from policy discussions.

This essay by Chunli Bai, executive vice president of the Chinese Academy of Sciences (CAS), explains the reasons behind the rapid progress of nanotechnology in China. A key factor, says Bai, has been "extraordinary" government support for the field since the early 1980s, which led to the creation of research institutes and significant grant money. But, cautions Bai, public communication on nanotechnology research, and ongoing monitoring and assessment of nanotechnology risks is needed.

Mohamed Hassan at the Academy of Sciences for the Developing World (TWAS) argues that the nanotechnology boom will not lead to a divide between developed and developing countries due to the transformation of 21st century global science. Hassan says Brazil, China and India are swiftly developing nanotech capabilities. Instead, he warns of a South-South divide as poorer nations struggle to catch up. To avoid this, Hassan recommends that developing nations create networks between universities and research centres to share nanotech expertise.
