Solar-powered drip irrigation Impacts on crops production diversity and dietary diversity in northern Benin

Halimatou Alaofe, Jennifer Burney, Rosamond L. Naylor, Douglas Taren
Food and Nutrition Bulletin, 2016 March 23, 2016
In 2007, "solar market gardens" were installed in 2 villages for women’s agricultural groups as a strategy for enhancing food and nutrition security. Data were collected through interviews at installation and 1 year later from all women’s group households (30–35 women/group) and from a random representative sample of 30 households in each village, for both treatment and matched-pair comparison villages. Comparison of baseline and endline data indicated increases in the variety of fruits and vegetables produced and consumed by SMG women’s groups compared to other groups.

The Evolving Sphere of Food Security

Rosamond L. Naylor
Oxford University Press, 2014 September 17, 2014

The Evolving Sphere of Food Security seeks to answer two important questions: How do the priorities and challenges of achieving food security change over time as countries develop economically? And how do the policies used to promote food security in one country affect nutrition, food access, natural resources, and national security in other countries? The volume presents the many faces and facets of food security—their symptoms, their roots, and their possible remedies—through the lens of a multidisciplinary group of scholars.

Does Aquaculture Add Resilience to the Global Food System?

Troell, M., Rosamond L. Naylor, M. Metian, M. Beveridge, P. Tyedmers, C. Folke, K. Arrow, S. Barrett, A-S. Crépin, P. Ehrlich, Å. Gren, N. Kautsky, S. Levin, K. Nyborg, H. Österblom, S. Polasky, M. Scheffer, B. Walker, T. Xepapadeas, A. de Zeeuw
PNAS, 2014 September 16, 2014

Aquaculture is the fastest growing food sector and continues to expand alongside terrestrial crop and livestock production. Using portfolio theory as a conceptual framework, we explore how current interconnections between the aquaculture, crop, livestock, and fisheries sectors act as an impediment to, or an opportunity for, enhanced resilience in the global food system given increased resource scarcity and climate change.

Feed and fishmeal use in the production of carp and tilapia in China

Alice Chiu, Luping Li, Shujing Guo, Junfei Bai, Chris Fedor, Rosamond L. Naylor
Aquaculture, 2013 November 15, 2013

China dominates the global aquaculture industry, most clearly with its massive production and consumption of low trophic-level carp species and its rapidly rising output and exports of tilapia. Although these fish do not require a high percentage of fishmeal in their diets, their large production volumes contribute to China's leading role in global fishmeal consumption. The magnitude of China's dependence on fishmeal supplies – and hence the pressure it places on wild forage fisheries – remains a contentious issue.

The case for distributed irrigation as a development priority in sub-Saharan Africa

Jennifer Burney, Rosamond Naylor, Sandra L. Postel
Proceedings of the National Academy of Sciences, 2013 July 24, 2013

Distributed irrigation systems are those in which the water access (via pump or human power), distribution (via furrow, watering can, sprinkler, drip lines, etc.), and use all occur at or near the same location. Distributed systems are typically privately owned and managed by individuals or groups, in contrast to centralized irrigation systems, which tend to be publicly operated and involve large water extractions and distribution over significant distances for use by scores of farmers.

Land institutions and supply chain configurations as determinants of soybean planted area and yields in Brazil

Rachael Garrett, Eric Lambin, Rosamond Naylor
Land Use Policy, 2012 October 1, 2012

Soybean production has become a significant force for economic development in Brazil. It has also received considerable attention from environmental and social non-governmental organizations as a driver of deforestation and land consolidation. While many researchers have examined the impacts of soybean production on human and environmental landscapes, there has been little investigation into the economic and institutional context of Brazilian soybean production or the relationship between soy yields and planted area.

Searching for Solutions in Aquaculture: Charting a sustainable course

Dane Klinger, Rosamond L. Naylor
Annual Reviews Environment and Resources, 2012 October 1, 2012

Aquaculture is currently the fastest growing animal food production sector and will soon supply more than half of the world’s seafood for human consumption. Continued growth in aquaculture production is likely to come from intensification of fish, shellfish, and algae production. Intensification is often accompanied by a range of resource and environmental problems. We review several potential solutions to these problems, including novel culture systems, alternative feed strategies, and species choices.

Redefining Security Along the Food-Health Nexus: report of a conference and center launch held at Stanford University on November 10, 2011

Rosamond Naylor, Ashley Dean
Food Security, 2012 March 1, 2012

For most scholars the concept of security encompasses issues of state legitimacy, economic and political sovereignty, and protection from military, nuclear, or terrorist assault. Yet billions of people, particularly in the developing world, face more severe, individual security threats on a daily basis, such as inadequate nutrition, disease burdens, lack of potable water, and risks of sexual assault or human trafficking. Such human security concerns can become national security issues when citizens rise up against their governments or threaten to rebel.

Smallholder irrigation as a poverty alleviation tool in sub-Saharan Africa

Jennifer Burney, Rosamond Naylor
World Development, 2011 November 21, 2011

Promotion of smallholder irrigation is cited as a strategy for enhancing income generation and food security for sub-Saharan Africa’s poor farmers, but what makes this technology a successful poverty alleviation tool? In the short run, the technology should pave the way for increased consumption, asset accumulation, and reduced persistent poverty among users. Over the longer run, it should lead to institutional feedbacks that support sustained economic development and nutritional improvements.

The Global Costs of American Ethanol

Rosamond Naylor, Walter Falcon
The American Interest, 2011 October 1, 2011

World leaders are focused on agricultural supply data, insurance schemes and speculation as they try to quell volatility in global food markets. They should also turn their attention to perhaps the leading cause of price instability: U.S. ethanol policy.

Expanding the Boundaries of Agricultural Development

Rosamond Naylor
Food Security, 2011 April 21, 2011

The challenges of reducing global hunger and poverty are different today than they were 30 years ago. Current challenges include price volatility associated with increased integration of food, energy, and finance markets; the steady progression of climate change; poorly defined land institutions; and a failure to break vicious cycles of malnutrition and infectious disease.

Impacts of El Nino-Southern Oscillation events on China's rice production

Deng Xiangzheng, Huang Jikun, Qiao Fangbin, Rosamond L. Naylor, Walter P. Falcon, Marshall Burke, Scott Rozelle, David Battisti
Journal of Geographcial Sciences, 2010 December 31, 2010

This paper aims to demonstrate the relationships between ENSO and rice production of Jiangxi province in order to identify the reason that ENSO might have little effect on Chinese rice production. Using a data set with measures of Jiangxi's climate and rice production, we find the reason that during 1985 and 2004 ENSO's well correlated with rainfall did not promote Chinese rice production. First, the largest effects of ENSO mostly occur in the months when there is no rice in the field. Second, there is almost no temperature effect.

Agriculture in Brazil: Impacts, Costs, and Opportunities for a Sustainable Future

Luiz Martinelli, Rosamond L. Naylor, Peter Vitousek, Paulo Moutinho
Current Opinion in Environmental Sustainability, 2010 December 1, 2010

Brazil has developed a large-scale commercial agricultural system, recognized worldwide for its role in domestic economic growth and expanding exports. However, the success of this sector has been associated with widespread destruction of Brazilian ecosystems, especially the Cerrado and the Brazilian Amazon rainforest, as well as environmental degradation. Brazil's agricultural development has also led to land consolidation, aggravating a historical land distribution inequality.

Food Security in an Era of Economic Volatility

Rosamond L. Naylor, Walter P. Falcon
Population and Development Review, 2010 December 1, 2010

The recent upheavals in staple food prices, financial markets, and the global economy raise questions about the state of food insecurity, the nature of price variability, and the appropriate strategies for international agricultural development. For decades preceding this turmoil, agriculture had received waning attention from the global development community as real food prices declined on trend. Analysts who worried about food insecurity focused on the fate of poor producers.

Solar-powered Drip Irrigation Enhances Food Security in the Sudano-Sahel

Jennifer Burney, Lennart Woltering, Marshall Burke, Rosamond L. Naylor, Dov Pasternak
Proceedings of the National Academy of Sciences, 2010 January 14, 2010

Meeting the food needs of Africa's growing population over the next half-century will require technologies that significantly improve rural livelihoods at minimal environmental cost. These technologies will likely be distinct from those of the Green Revolution, which had relatively little impact in sub-Saharan Africa; consequently, few such interventions have been rigorously evaluated. This paper analyzes solar-powered drip irrigation as a strategy for enhancing food security in the rural Sudano-Sahel region of West Africa.
