Agriculture

Paragraphs

Wheat is a staple crop throughout much of India, but in many areas it is commonly sown past the optimum window for yields. Recent technologies, such as adoption of no-till practices or earlier maturing cotton and rice varieties, have enabled some farmers to sow wheat earlier, but repeatable and publicly available measurements of sow date trends are lacking. Here we utilize satellite measurements since 2000 to estimate sow dates over a decade throughout wheat growing areas in India. Comparisons with ground-based sow dates in Punjab confirmed the reliability of satellite estimates, and data from two independent satellite sensors were used as a robustness check. We find statistically significant (p < 0.05) shifts toward earlier sowing of wheat throughout much of Haryana and Uttar Pradesh, with insignificant changes in Punjab. A production-weighted average of the entire region indicates that, on average, wheat was sown 1 week earlier by 2010 than it was at the beginning of the decade. Using previously published experimental estimates of yield gains from earlier sowing, we estimate that an overall yield gain of at least 5% averaged across India can be explained by the sow date trend. Given that national yield changes since 2000 have been less than 5%, our results indicate that the sow date shift has been a major factor in yield changes over the past decade, and that the net yield effect of all factors other than sow date has been close to zero, perhaps even negative. The results also indicate that sow dates in much of Haryana and western Uttar Pradesh are nearing or already at the optimum window for yields, so that yield benefits from sow date shifts will likely diminish in the next decade.

Paragraphs

Outside of China, the world now has more food insecure and nutrient deficient people than it had a decade ago, and the prevalence of obesity-related diabetes, high blood pressure and cardio-vascular diseases is increasing at very rapid rates. Expanded food production has done little to address the fact that between one-third and one-half of all deaths in children under five in developing countries are still related to malnutrition.

“With only three years away from the Millennium Development Goals deadline, this is a terrible track record,” said food and nutrition policy expert Per Pinstrup-Andersen at FSE's Global Food Policy and Food Security Symposium Series last week.

Pinstrup-Andersen, the only economist to win the World Food Prize (the ultimate award in the food security field), has dedicated his career to understanding the linkages between food, nutrition, and agriculture. What is driving persistent food insecurity and malnutrition in a food abundant world?

Poor food supply management is part of the problem. According to the United Nations Food and Agricultural Organization (FAO), 20-30% of food produced globally is lost every year. That’s enough to feed an additional 3-3.5 billion people.

Biofuels production, such as jatropha in Africa, now competes with food for land, and climate change is already negatively impacting crop yields in regions straddling the equator—with major implications for food supply.

For low-income consumers in both the U.S. and developing countries increasing and more volatile food prices, such as those seen in 2007, are also driving food insecurity. Poor consumers respond by purchasing cheaper, less nutrient food, and less of it.

Nutritional value chain

Consensus is developing—at least rhetorically—among national policymakers and international organizations that investments in agricultural development must be accelerated. Members of the G8 and G20 have committed $20 billion in international economic support for such investments and some developing countries such as Ethiopia and Ghana are planning large new investments.

While most of these recent initiatives focus on expanded food supplies, there is an increasing understanding that merely making more food available will not assure better food security, nutrition, and health at the household and individual levels.

“It matters for health and nutrition how increasing food supplies are brought about and of what it consists,” said Pinstrup-Andersen. “We need to turn the food supply chain into a nutritional value chain.”

Diet diversity is incredibly important for good nutrition. Agricultural researchers and food production companies need to look at a number of different commodities, not just the major food staples, said Pinstrup-Andersen.

“The Green Revolution successfully increased the production of corn, rice, and wheat, increasing incomes for farmers, and lowering prices for consumers, but now it is time to invest in fruits, vegetables and biofortification to deal with micronutrient deficiency,” said Pintrup-Andersen.

Biofortification, the breeding of crops to increase their nutritional value, offers tremendous opportunity for dealing with malnutrition in the developing world, but is not widely available.

This is particularly important for areas in sub-Saharan Africa where between one and three and one and four people are short in calories, protein, and micronutrients. Obesity is actually going up in these countries with the introduction of cheap, processed, energy-dense foods (those high in sugar and fat) contributing to the diabetes epidemic.

Pathways to better health

The path to better health and nutrition must look beyond the availability of food at affordable prices, clean water, and good sanitation, and consider behavioral factors such as time constraints for women in low-income households.

“Field studies have shown time and time again that one of the main factors preventing women from providing themselves and their families with good nutrition is time,” explained Pinstrup-Andersen.

He told the story of a woman in Bolivia too burdened with farm and household responsibilities to take the time to breastfeed her six-month old daughter. Enhancing productivity in activities traditionally undertaken by women could be a key intervention to improving good health and nutrition at the household level.

Access is another issue. A household may be considered food secure, in that sufficient food may be available, but food may not be equally allocated in the household.

“If we focus on the most limiting constraint we can be successful,” said Pinstrup-Anderen. “But we must tailor our response to each case.”

For sub-Saharan Africa, this includes investments in rural infrastructure, roads, irrigation systems, micronutrient fertilizer, climate adaptation strategies, and other barriers holding back small farmers.

Fortunately, there has been a renewed attention to the importance of guiding food system activities towards improved health and nutrition. The Global Agriculture and Food Security Program (GAFSP), which facilitates the distribution of some of the G8 and G20 $20 billion commitments, prescribes that country proposals for funding of agricultural development projects must show a clear pathway from the proposed agricultural change to human nutrition.

“But it’s not going to be easy to implement good policies,” warned Pinstrup-Andersen. “There are few incentives in government for multidisciplinary problem solving. The economy is set up around silos and people are loyal to their silos. Agricultural and health sectors are largely disconnected in their priorities, policy, and analysis."

Incentives must change to encourage working across ministries and disciplines to identify the most important health and nutrition-related drivers of food systems, impact pathways, and policy and program interventions to find win-wins for positive health and nutrition.

Africa's Food Systems in 2030

Tuesday, February 5, 2013 | 3:00 PM -Tuesday, February 5, 2013 | 5:00 PM

Paul Collier will talk about how to manage the difference between helpful and damaging commercialisation, and puts forth three arguments. First, we need to face the tough reality that African food production has failed to keep pace with demand over the course of several decades, suggesting that there is a deep problem with respect to innovation and investment given the way African agriculture has been organised. Second, we need to accept that climate change, population growth, and income gains from natural resources will all stress this imbalance further: the prospect is for widening food deficits with business as usual. Third, two major changes are afoot. Globally, the model of commercial tropical agriculture pioneered in Brazil has demonstrated that output can be raised very substantially by changing the mode of organisation. Africa is now starting to open land markets to large foreign management. Superficially this looks like Brazil2, but it may instead be a wave of speculative acquisitions triggered by the price peaks of 2008.

Collier is the Director of the Centre for the Study of African Economies and Professor of Economics and Public Policy at the Blavatnik School of Government, Oxford University. He is currently Advisor to the Strategy and Policy Department of the IMF, advisor to the Africa Region of the World Bank; and he has advised the British Government on its recent White Paper on economic development policy. He has been writing a monthly column for the Independent, and also writes for the New York Times, the Financial Times, the Wall Street Journal, and the Washington Post. His research covers the causes and consequences of civil war; the effects of aid and the problems of democracy in low-income and natural-resources rich societies.

Derek Byerlee's talk will lay out a number of models of inclusive agribusiness growth, grouped into three categories (i) institutional arrangements for improving productivity of smallholders operating in spot markets, (ii) various types of contract farming arrangements, and (iii) large-scale farms that generate jobs and/or include community equity shares. The institutional and policy context as well as commodity characteristics that favor these models are discussed within a simple transactions cost framework. He will also discuss cross-cutting policy priorities to enable the growth of commercial agriculture and agribusiness. These include continuing reforms to liberalize product and input markets, access to technology and skills, stimulating financial and risks markets, securing land rights, and investment in infrastructure through public-private partnerships.

Byerlee has dedicated his career to agriculture in developing countries, as a teacher, researcher, administrator and policy advisor. He has lived and worked for a total of 20 years in the three major developing regions-Africa, Asia, and Latin America. After beginning in academia at Michigan State University, he spent the bulk of his career at the International Maize and Wheat Improvement Center (CIMMYT). There as a economist and research manager he made notable contributions in forging a new spirit of collaboration between scientists, economists and farmers. He also published widely on efficiency of research systems, spillovers, and sustaining productivity in post green revolution agriculture. After joining the World Bank in 1994, he has applied his experience of research systems to finding innovative approaches to funding and organizing agricultural research, including emerging challenges in biotechnology policy. Since 2003, he has provided strategic direction and led policy world for the agricultural and rural sector in the World Bank.

China and Africa: Are there Lessons for Development?

Wednesday, April 17, 2013 | 3:30 PM -Wednesday, April 17, 2013 | 5:30 PM

The lost decades for China in the 1950s, 1960s and 1970s look remarkably like the lost decades of Africa in the 1980s and 1990s. Poor land rights, weak incentives, incomplete markets and inappropriate investment portfolios. However, China burst out of its stagnation in the 1980s and has enjoyed three decades of remarkable growth. In this talk Rozelle examines the record of the development of China’s food economy and identifies the policies that helped generate the growth and transformation of agriculture. Incentives, markets and strategic investments by the state were key. Equally important, however, is what the state did not do. Policies that worked and those that failed (or those that were ignored) are addressed. Most importantly, Rozelle tries to take an objective, nuanced look at the lessons that might be learned and those that are not relevant for Africa. Many parts of Africa have experienced positive growth during the past decade. Rozelle examines if there are any lessons that might be helpful in turning ten positive years into several more decades of transformation.

Scott Rozelle (main speaker). Scott Rozelle is the Helen F. Farnsworth Senior Fellow and the co-director of the Rural Education Action Program in the Freeman Spogli Institute for International Studies at Stanford University. His research focuses almost exclusively on China and is concerned with: agricultural policy, including the supply, demand, and trade in agricultural projects; the emergence and evolution of markets and other economic institutions in the transition process and their implications for equity and efficiency; and the economics of poverty and inequality, with an emphasis on rural education, health and nutrition.

Alain de Janvry (commentator). Alain de Janvry is an economist working on international economic development, with expertise principally in Latin America, Sub-Saharan Africa, the Middle-East, and the Indian subcontinent. Fields of work include poverty analysis, rural development, quantitative analysis of development policies, impact analysis of social programs, technological innovations in agriculture, and the management of common property resources. He has worked with many international development agencies, including FAO, IFAD, the World Bank, UNDP, ILO, the CGIAR, and the Inter-American Development Bank as well as foundations such as Ford, Rockefeller and Kellogg. His main objective in teaching, research, and work with development agencies is the promotion of human welfare, including understanding the determinants of poverty and analyzing successful approach to improve well-being and promote sustainability in resource use.

How can trade improve food security in sub-Saharan Africa?

Wednesday, January 23, 2013 | 3:30 PM -Wednesday, January 23, 2013 | 5:30 PM

For decades, earnings from farming in many developing countries, including in sub-Saharan Africa, have been depressed by a pro-urban bias in own-country policies, as well as by governments of richer countries favouring their farmers with import barriers and subsidies. Both sets of policies reduced global economic welfare and agricultural trade, and almost certainly added to global inequality and poverty and to food insecurity in many low-income countries. Progress has been made over the past three decades in reducing the trend levels of agricultural protection in high-income countries and of agricultural disincentives in African and other developing countries. However, there is a propensity for governments to insulate their domestic food market from fluctuations in international prices, and that has not waned. That action amplifies international food price fluctuations, yet when both food-importing and food-exporting countries so engage in insulating behaviour, it does little to advance their national food security. Anderson argues much scope remains to improve economic welfare and reduce poverty and food insecurity by removing trade distortions. He summarizes indicators of these trends and fluctuations in trade barriers before pointing to changes in both border policies and complementary domestic measures that together could improve African food security.
