Sustainable palm oil? How environmental protection and poverty reduction can be reconciled

Palm oil is often associated with tropical deforestation above all else. However, this is only one side of the story, as Matin Qaim and colleagues from the University of Göttingen and the IPB University Bogor (Indonesia) show in a new review article. The rapid expansion of oil palm has also contributed considerably to economic growth and poverty reduction in local communities, particularly in Asia. The article was published in the Annual Review of Resource Economics.

New Study on Supermarkets and Child Nutrition in Africa

Undernutrition remains a widespread problem in Africa. At the same time, overweight, obesity, and related chronic diseases are also on the rise. Recent research suggested that the growth of supermarkets contributes to obesity in Africa, because supermarkets tend to sell more processed foods than traditional markets. But previous studies only looked at adults. In a new study, Bethelhem Legesse Debela and coauthors from the University of Goettingen used data from children in Kenya to analyze effects of supermarkets on nutrition. They show that supermarkets are not linked to obesity in children, but that supermarkets instead help reduce child undernutrition and contribute to gains in child height. The positive nutrition effects are channeled through improvements in food variety and dietary diversity. The results were recently published in Global Food Security.

Fairtrade benefits rural workers in Africa, but not the poorest of the poor

A new study from our team has analyzed the effects of Fairtrade certification on poor rural workers in Africa. The results show that Fairtrade improves the situation of employees in agricultural cooperatives, but not of workers in the smallholder farm sector, who are often particularly disadvantaged. The study was published in Nature Sustainability. When consumers of cocoa, coffee and other tropical goods, decide to purchase products with the Fairtrade label, they pay a certain premium, expecting to help improve the socioeconomic conditions in developing countries. We wanted to know whether Fairtrade really benefits poor rural workers in Africa. For the study, we collected representative data from 1000 cocoa farmers and workers in 50 different cooperatives in Cote d’Ivoire. Cote d’Ivoire in West Africa is the largest cocoa producer and exporter worldwide. Previous studies had analyzed the effects of Fairtrade on smallholder farmers, ignoring that these farmers also employ agricultural workers for crop cultivation and harvesting. Workers in the small farm sector constitute a large group. They are often neglected by development initiatives, although they typically belong to the poorest of the poor. Fairtrade requires minimum wages and fair labor conditions for workers and employees in certified value chains. These conditions are met for the employees in cocoa cooperatives. At the cooperative level, Fairtrade requirements are regularly monitored. However, our data show no effects on the livelihoods of farmworkers, even though the farmers themselves benefit from Fairtrade certification. Monitoring the wages and labor conditions on thousands of small farms is costly and therefore rarely done. But it doesn’t work without monitoring. Better solutions have to be found in order to implement the fairness model more comprehensively. (Meemken, E.M., Sellare, J., Kouame, C., Qaim, M., 2019.

Science Article: New Plant Breeding Technologies for Food Security

In a perspective article published recently in Science, Matin Qaim and an international team of co-authors argue that new plant breeding technologies – such as genome editing – can contribute significantly to food security and sustainable development. Also in the past, plant breeding and other agricultural technologies played an important role for food security, but the resulting high intensity in the use of agrochemicals has caused serious environmental problems as well. Future technologies need to reduce the environmental footprint and make agriculture more resilient to climate stress. Predictions suggest that small farms in Africa and Asia will suffer especially from the effects of climate change. Genome editing can be used to make crop plants more resistant to pests and diseases and more tolerant to drought and heat. This can help to reduce crop losses and chemical pesticide sprays. Methods such as CRISPR/Cas can be used to make precise point mutations without introducing foreign genes. Due to their low costs, these methods can also be employed in previously neglected crops, such as pulses and local vegetables. In the article, the authors show which concrete genome-edited crops could become available within the next five years. But they stress that international cooperation, public support, and efficient science-based regulation will be important to ensure that the poorest countries and the poorest farmers can also benefit.

Meta-analysis of the association between farm production diversity and nutrition

Undernutrition and low dietary diversity remain big problems in many developing countries. A large proportion of the people affected are smallholder farmers. Hence, it is often assumed that further diversifying small-farm production would be a good strategy to improve nutrition. But the evidence is mixed. In a new paper published in Food Policy, Kibrom Sibhatu and Matin Qaim provide a meta-analysis of available studies. The average effect of farm production diversity on dietary diversity is positive but small. The mean effect of 0.062 implies that farms would have to produce 16 additional crop or livestock species to increase dietary diversity by one food group. The mean effect is somewhat larger in Sub-Saharan Africa than in other regions, but even in Africa farms would have to produce around 9 additional species to increase dietary diversity by one food group. While results may look differently under very specific conditions, there is little evidence to support the assumption that increasing farm production diversity is a highly effective strategy to improve smallholder diets and nutrition in most or all situations.

Can organic agriculture sustainably feed the world?

Organic agriculture is often perceived as more sustainable than conventional farming. In a recent article published in the Annual Review of Resource Economics, Eva-Marie Meemken and Matin Qaim reviewed the literature from a global perspective. In terms of environmental and climate change effects, the researchers show that organic farming is less polluting than conventional farming when measured per unit of land but not when measured per unit of output. Organic farming, which currently accounts for only1% of global agricultural land, is lower yielding on average. Due to higher knowledge requirements, observed yield gaps might further increase if a larger number of farmers would switch to organic practices. Widespread upscaling of organic agriculture would cause additional loss of natural habitats and also entail output price increases, making food less affordable for poor consumers in developing countries. Meemken and Qaim conclude that organic farming is not the paradigm for sustainable agriculture and food security. But they also suggest that smart combinations of organic and conventional methods could contribute toward sustainable productivity increases in global agriculture.

Eradicating hunger in all its forms

Eradicating hunger in all its forms, including chronic hunger (calorie deficiencies) and hidden hunger (micronutrient deficiencies), requires good understanding of the problem’s magnitude, trends, and determinants. Existing studies measure “hunger” through different proxies that all have their shortcomings. In a new study published in (Golbal Food Security), Theda Gödecke, Alexander Stein, and Matin Qaim have used a more comprehensive metric, Disability-Adjusted Life Years (DALYs), to quantify the burden of hunger and to analyze related trends. While the burden of chronic hunger more than halved since 1990, it remains larger than the burden of hidden hunger. Based on cross-country regressions, the authors show that economic growth was a major determinant of reducing the hunger burden. However, the analysis also reveals that growth and other country-level determinants have larger effects on the burden of chronic hunger than on the burden of hidden hunger. Hence, in addition to general development efforts, targeted micro-level interventions are required to end hunger in all its forms. (link to open access article)

Göttingen agricultural economists Dr. Wilhelm Klümper and Prof. Dr. Matin Qaim received the InnoPlanta Science Prize 2015 for their work on the economics of genetically modified crops. The Prize is annually awarded by InnoPlanta for objective and publicly visible research work in the wider area of plant biotechnology. In particular, Klümper and Qaim received the prize for their paper 'A meta-analysis of the impacts of genetically modified crops' that was published in the journal 'PLOS ONE' in 2014. The paper had received international mass media attention. The Prize was awarded on 17 November in Berlin during the InnoPlanta-Forum.

Meta-analysis of the impacts of GM crops

Wilhelm Klümper and Matin Qaim have carried out a meta-analysis of the agronomic and economic impacts of GM crops, covering 147 original studies that were carried out internationally over the last 20 years. On average, GM technology adoption has reduced chemical pesticide use by 37%, increased crop yields by 22%, and increased farmer profits by 68%. Yield gains and pesticide reductions are larger for insect-resistant crops than for herbicide-tolerant crops. Yield and profit gains are higher in developing countries than in developed countries. The meta-analysis reveals robust evidence of GM crop benefits. Such evidence may help to gradually increase public trust in this technology. The results were recently published in PLOS ONE. Several large newspapers reported about the results, including The Economist, Frankfurter Allgemeine Zeitung, and several others.

Genetically Modified Crops and Food Security

Matin Qaim and Shahzad Kouser from the University of Goettingen have shown in a new study that the introduction of genetically modified (GM) cotton has improved the nutrition situation in India, the country with the largest number of undernourished people worldwide. The researchers have used data from over 500 randomly selected small-farm households, which they had surveyed regularly over a 7-year period. The adoption of GM cotton has increased yields and incomes, enabling farm families to afford more and better food. Calorie consumption and dietary quality have improved significantly. By now, more than 90% of all cotton farms in India have switched to GM technology. As a result, food insecurity was reduced by 15-20% among cotton-growing households. The study was published recently in the academic journal “PLOS ONE” (click here for full text open access).

Agricultural Economists on Bt Cotton Impacts in India

The controversy about Bt cotton impacts in India continues. Recently, India’s Committee on Agriculture released a report stating that Bt cotton would not benefit poor farmers. As a reaction, 65 independent agricultural economists and political scientists prepared a statement in which they criticize the Committee’s report as biased and ignorant of the large scientific evidence on Bt cotton benefits for farmers in India. Supporters of this statement include eminent Indian and international scholars in the field of agricultural development and technology evaluation. The statement was sent to the Indian Prime Minister and Minister of Agriculture.

Josef G. Knoll Science Prize for Elisabeth Fischer

Elisabeth Fischer receives the Josef G. Knoll Science Prize 2012 for her doctoral dissertation titled “Determinants and impacts of smallholder collective action in Kenya”, which she recently completed under the guidance of Prof. Matin Qaim. Using primary data and econometric analyses, Fischer showed in her research that farmer groups can improve access to markets and new technologies, thus contributing to higher household incomes. Yet, she also finds that group structure and other institutional details influence outcomes and gender implications significantly. The Josef G. Knoll Science Prize is awarded every two years by the Fiat Panis Foundation for outstanding research related to hunger and poverty reduction.

Jonas Kathage and Prof. Dr. Matin Qaim publish new paper on GM crop impacts in India

Genetically modified (GM) crops are often criticized, but a new study published in the Proceedings of the National Academy of Sciences (PNAS) finds that at least one such crop—cotton engineered to resist a common insect pest— has significantly raised the living standards of smallholder farm households in India. Jonas Kathage and Matin Qaim from the University of Goettingen conducted surveys between 2002 and 2008 of 533 households in four principal cotton-producing Indian states. The sample included farmers who grew the GM crop, called Bt cotton, and those who did not. The former increased cotton yields and profits by 24% and 50% respectively. The researchers attribute the increases to reduced damage from the cotton bollworm. They further determined that household living standard increased by 18% among Bt cotton farmers once the growers realized that the profit gains are sustainable. The benefits even appear to have increased over time. Since most of the farmers are relatively poor, the gains have made a substantial positive impact on their lives. The findings refute an earlier assertion that GM crop technology would harm smallholder farmers due to low and eroding economic benefits. Since Bt cotton is the only such crop that is already widely grown by smallholder farmers, the study may add to the wider public biotechnology debate.
