FSI scholars approach their research on the environment from regulatory, economic and societal angles. The Center on Food Security and the Environment weighs the connection between climate change and agriculture; the impact of biofuel expansion on land and food supply; how to increase crop yields without expanding agricultural lands; and the trends in aquaculture. FSE’s research spans the globe – from the potential of smallholder irrigation to reduce hunger and improve development in sub-Saharan Africa to the devastation of drought on Iowa farms. David Lobell, a senior fellow at FSI and a recipient of a MacArthur “genius” grant, has looked at the impacts of increasing wheat and corn crops in Africa, South Asia, Mexico and the United States; and has studied the effects of extreme heat on the world’s staple crops.
Social and environmental transformation in Chile's aquaculture industry, 1950-2000
Chile's once-fledgling salmon aquaculture industry is now the second largest in the world. Since 1990, the industry has grown 24-fold and now annually exports more than half-a-million tons of fish worth billions of dollars. But that massive economic growth has had equally massive environmental and social effects.
Mobile Phones and Economic Development in Africa
Mobile phones are transforming lives in low-income countries faster than ever imagined. The effect is particularly dramatic in rural areas of sub-Saharan Africa, where mobile phones have often represented the first modern infrastructure of any kind. The iconic image of cell phones in Africa is the market woman, surrounding by her goods while making calls to potential clients in the capital city. Equally common are the slogans of mobile phone companies promising a better life for those who use it.
Yet do these images and slogans reflect the reality of what cell phones can do? Cell phones are being adopted by the rural and urban poor at a surprising rate, far exceeding cell phone companies' projections. An emerging body of research suggests that mobile phones are improving households' access to information and reducing costs, thereby making markets more efficient and increasing incomes. These impacts have occurred without NGOs or donor investments - but as a positive externality from the IT sector.
Governments, donors and NGOs have noticed the potential of information technology in achieving development goals in a variety of sectors, including agriculture, education, health, financial services and governance. Mobile phones can greatly facilitate the effectiveness of development programs, but are needed in partnership with the private sector. And while cell phone coverage reaches over 60% of the population in most African countries, other constraints to cell phone adoption - namely pricing and handset cost - should be addressed.
Jenny Aker has worked extensively in Central, North and West Africa for the past ten years for NGOs, international organizations and universities. Her research uses field work and field experiments to better understand field-driven development problems, primarily by teaming up with NGOs and program implementers in an effort to link research with policy and implementation.
Jenny is currently involved in three main areas of research. The first assesses the impact of information technology (mobile phones) on development outcomes, namely farmers’ and traders’ welfare, market performance, labor outcomes, literacy rates and early warning systems. Based upon her previous work in Niger, she is collaborating with Catholic Relief Services in Niger on Project ABC (Alphabétisation de Base par Cellulaire), which uses cell phones as a learning tool to allow literacy participants to read and write in their local languages via SMS. The project takes a rigorous impact evaluation approach, assessing the impact of cell phones on literacy rates and farmers’ marketing behavior. Her second area of research involves assessing the impact of climate change on farmer-herder conflicts in the Sahel, with a particular focus on Mali. Her third area of research evaluates the impact of specific development interventions -- including food aid distributions, local purchases, and cash vouchers – on producers’ welfare and market performance in the Sahel.
In September 2009, Jenny joined Tufts University as an Assistant Professor in the Economics Department and Fletcher School of Law and Diplomacy.

Proliferation Resistance of Nuclear Technologies: Conversion of Research Reactors and Other Case Studies
Ambivalent nuclear technologies use or have a potential to produce nuclear weapon relevant materials like highly enriched uranium (HEU), plutonium, tritium and U233. It is important to assess the proliferation potential and measures to strengthen the proliferation resistance of these technologies as early as possible (preventively) to find alternative more proliferation resistant designs or at least to identify sensitive parameters or even critical parts that should trigger international safeguards and export controls.
The conclusions of different case studies investigating the proliferation resistance of nuclear technologies such as spallation neutron sources, tokamak fusion reactors and plutonium fuels will be briefly presented. The main part of the talk will focus on the minimization or elimination of civil HEU usage and the role of research reactor conversion to the use of low enriched uranium, which is intrinsically more proliferation resistant. The conversion of the German high flux research reactor FRM-II will serve as an example for the complex political and technological challenges and problems one has to face, especially, if proliferation concerns are not taken seriously in the research and design phase. These case studies of relatively disparate nuclear technologies have in common that they are neutron producing technologies and some questions regarding their proliferation potential can be addressed using neutronic codes.
Finally, the talk will briefly outline the future research of the next year addressing centrifuge technology as another case study to explicate on exemplary basis general criteria for the proliferation resistant use of nuclear technologies.
Matthias Englert is a
postdoctoral fellow at CISAC. Before joining CISAC in 2009, Matthias was a
researcher at the Interdisciplinary Research Group Science Technology and
Security (IANUS) and a PhD student at the department of physics at Darmstadt
University of Technology in Germany.
His major research interests include nonproliferation, disarmament, arms control, nuclear postures and warheads, fissile material and production technologies, the civil use of nuclear power and its role in future energy scenarios and the possibility of nuclear terrorism. His research during his stay at CISAC focuses primarily on the technology of gas centrifuges for uranium enrichment, the implications of its use for the nonproliferation regime and on technical and political measures to manage the proliferation risks.
Matthias has been participating in projects investigating technical aspects of the concept of proliferation resistance with topics spanning from conversion of research reactors, uranium enrichment with gas centrifuges, reducing plutonium stockpiles with reactor based options, spallation neutron sources and fusion power plants. Further research topics included fissile material stockpiles, fuel-cycles and accelerator driven systems. Although a substantial part of his professional work of the last years was quite technical he is equally interested in and actively studies the historical, social and political aspects of the use of nuclear technologies. Research interests include the dispute about Article IV of the NPT, the future development of the NPT regime, possibilities for a nuclear weapon free world, preventive arms control, and history and development of proliferation relevant programs. By studying contemporary theory in philosophy of the interaction of science, technology and society, Matthias acquired analytical tools to reflect on approaches describing or addressing the problem of ambivalent technology.
Matthias is a vice speaker of the working group Physics and Disarmament of the German Physical Society (DPG) and a board member of the German Research Association for Science, Disarmament and Security (FONAS).

Promoting Clean Development Competing Market Mechanisms Post-2012
(Excerpt) According to climate scientists, averting the worst consequences of climate change requires that the increase in global temperature should be limited to 2°C (or 3.6°F). to achieve that objective, global emissions of green house gases (GHGs)—the main human cause of global warming—must be reduced to 50 percent of 1990 levels by 2050.
The key to successful climate change abatement at those scales lies in leveraging the collective actions of developed and developing countries. Cumulatively, developed countries have been responsible for most human emissions of GHGs. that picture will be quite different in the future as emissions from the developing world take over the top mantle. Given this dynamic, there is a general agreement internationally that developed countries will lead emissions reductions efforts and that developing countries will follow with “nationally ap- propriate mitigation actions.” turning that agreement into environmentally beneficial action requires close international coordination between the developed and developing countries in allocating the responsibility for the necessary reductions and following up with credible actions. However, the instruments employed so far to promote the necessary collective action have proved to be insufficient, unscalable, and questionable in terms of environmental benefit and economic efficiency.
Currently, the most important and visible link be- tween developed and developing countries’ efforts on climate change is the Clean development Mechanism (CdM). the CdM uses market mechanisms—the “carbon markets”—to direct funding from developed countries to those projects in developing countries that lead to reductions in emissions of warming gases. In reality, the experience with the CdM has been mixed at best since its inception in 2006. while the CdM has successfully channeled funding to many worthy projects that reduce emissions of warming gasses, it has also spawned myriad projects with little environmental benefits. overall, the CdM has led to a significant overpayment by developed countries for largely dubious emissions reductions in developing countries.
Cookstoves and Obstacles to Technology Adoption by the Poor
Programs to distribute improved biomass stoves have traditionally been unsuccessful, despite enormous potential health and climate benefits. This research note helps explain the reasons for this by considering three main prerequisites for technology adoption by the poor. The first success factor is motivation on the part of customers to adopt the new product. When motivation does not exist initially, it must be created through education, social marketing, or improved design. The second essential component is that the product be affordable, be it through disposable income, financing, or subsidies. Finally, the success of a product is dependent on the level of user engagement necessary to take advantage of it.
Improved cookstoves rank poorly on all three dimensions: their benefits are rarely valued highly by customers at the outset, they are expensive, and they require a significant change in lifestyle to be put into use.
These three potential barriers to adoption are relevant to any product aimed at consumers at the "bottom of the pyramid" in income. They help explain why some products (for example, Coca-Cola and cell phones) have penetrated markets rapidly while others such as cookstoves have achieved very limited penetration.
