Synopsis: Cities and agricultural transformation in Africa: Evidence from Ethiopia

Due to the rapid growth of cities in Africa, many more farmers are now living in rural hinterlands in relatively close proximity to cities. However, empirical evidence on how urbanization affects these farmers is scarce. To fill this gap, this paper explores the relationship between proximity to a city and the production behavior of rural staple crop producers. In particular, we analyze data from teff farmers in major teff producing areas around Addis Ababa, the Ethiopian capital. We find that farmers located closer to Addis Ababa face higher wages and land rental prices, but because they receive higher teff prices they have better incentives to intensify production. Moreover, we observe that modern input use, land and labor productivity, and profitability in teff production improve with urban proximity. This urban proximity has a strong and significant effect on these aspects of teff production, possibly related to the use of more formal factor markets, lower transaction costs in crop production and marketing, and better access to information. In contrast, we do not find a strong and positive relationship between rural population density increases and agricultural transformation – increased population density seems to lead to immiserizing effects in these settings. Our results show that urban proximity should be considered as an important determinant of the process of agricultural intensification and transformation in developing countries

Secondary towns, agricultural prices, and intensification: Evidence from Ethiopia

Urbanization is happening fast in the developing world and especially so in sub-Saharan Africa where growth rates of cities are among the highest in the world. While cities and, in particular, secondary towns, where most of the urban population in sub-Saharan Africa resides, affect agricultural practices in their rural hinterlands, this relationship is not well understood. To fill this gap, we develop a conceptual model to analyze how farmers’ proximity to cities of different sizes affects agricultural prices and intensification of farming. We then test these predictions using large-scale survey data from producers of teff, a major staple crop in Ethiopia, relying on unique data on transport costs and road networks and implementing an array of econometric models. We find that agricultural price behavior and intensification is determined by proximity to a city and the type of city. While proximity to cities has a strong positive effect on agricultural output prices and on uptake of modern inputs and yields on farms, the effects on prices and intensification measures are lower for farmers in the rural hinterlands of secondary towns compared to primate cities.

Domestic versus export-led agricultural transformation: Evidence from Uganda’s dairy value chain

Driven by increased demand from both local and export markets and facilitated by far-reaching liberalization and privatization policies, the dairy sub-sector in Uganda has undergone significant changes in the last decade. With a comparative advantage in milk production, the southwest of Uganda has started to attract considerable Foreign Direct Investment (FDI) in processing capacity, mainly targeting the export market. As a result, processing capacity increased five-fold and dairy became Uganda’s third most important export product, coming from negligible amounts a decade earlier. In this study, we use observational data collected at different nodes within the value chain to compare the structure of the chain and the roles and economic activities of different actors between export-led value chains and value chains that cater for the local market. Doing so allows us to identify the technological and institutional innovations that both result from the emergence of export-led dairy value chains and at the same time drive further upgrading. Our analysis underscores the importance of milk collection centers, which often take the form of farmer cooperatives, in providing many of the support services that enable other actors in the value chain to produce sufficient milk, and maintain milk sanitation levels necessary for an export sector to emerge.

Cities and agricultural transformation in Africa: Evidence from Ethiopia

Due to the rapid growth of cities in Africa, many more farmers are now living in rural hinterlands in relatively close proximity to cities where many provide food to urban residents. However, empirical evidence on how urbanization affects these farmers is scarce. To fill this gap, this paper explores the relationship between proximity to a city and the production behavior of rural staple crop producers. In particular, we analyze data from teff producing farmers in major producing areas around Addis Ababa, the Ethiopian capital. We find that farmers located closer to Addis Ababa face higher wages and land rental prices, and because they receive higher teff prices they have better incentives to intensify production. Moreover, we observe that modern input use, land and labor productivity, and profitability in teff production improve with urban proximity.

Big cities, small towns, and poor farmers: Evidence from Ethiopia

Urbanization is happening fast in the developing world and especially so in sub-Saharan Africa where growth rates of cities are among the highest in the world. While cities and, in particular, secondary towns, where most of the urban population in sub-Saharan Africa resides, affect agricultural practices in their rural hinterlands, this relationship is not well understood. To fill this gap, we develop a conceptual model to analyze how farmers’ proximity to cities of different sizes affects agricultural prices and intensification of farming. We then test these predictions using large-scale survey data from producers of teff, a major staple crop in Ethiopia, relying on unique data on transport costs and road networks and implementing an array of econometric models.

Trade, value chains, and rent distribution with foreign exchange controls: Coffee exports in Ethiopia

Exchange rate policies can have important implications on incentives for export agriculture. However, their effects are often not well understood. We study the issue of foreign exchange controls and pricing in the value chain for Ethiopia’s coffee – its most important export crop. Relying on unique pricing and cost data, we find that coffee exporters are willing to incur losses during exporting by offering high prices for coffee locally in order to access scarce foreign exchange. The losses in export markets are then more than recovered in importing, indicating rents – import parity prices are significantly lower than the prices charged for imported goods, so that profits on imports are much higher than the losses incurred in exporting. We further show that the high coffee wholesale prices are transmitted to farmers, so that they benefit from the rents downstream. These results suggest that a better exchange rate alignment to reduce the overvaluation of the local currency in this case would have a lower impact on export crop producer prices than typically is anticipated.

Famine in Gaza, questions for research and preventive action

The ongoing humanitarian crisis in Gaza is unprecedented in terms of the share of the population experiencing acute food insecurity and famine and the speed of the onset of the crisis. Research can help understand and anticipate the long-term impacts of the conflict on people and livelihoods, design more effective humanitarian support systems and identify options for creating resilient post-conflict livelihoods.

Market power and the volatility of markups in the food value chain: The role of Italian cooperatives

Agricultural cooperatives have often been promoted as a way to increase their market power and to obtain stability of profit against uncertainty. This paper estimates the firm-level markups and markup volatility to identify the countervailing market power of cooperatives in the Italian fruits and vegetable sector and the dairy sector. We use the firm-level data of Italian firms for the period 2007-2014. We find that, overall, there is a tradeoff in cooperatives’ role between obtaining market power and stability. Farmer cooperatives in both sectors gain stability in their markups but their markups are lower, on average, than those for non-cooperatives. For processor cooperatives, the fruits and vegetable sector obtains more market power. This appears to arise from the product differentiation strategy of the processors cooperative.

Globalization and political economy of food policies: Insight from planting restrictions in colonial wine markets

Globalization transforms not just the economics of production and exchange in the world, but also the political economy of public policies. We analyze how wine regulations, and more specifically planting rights restrictions, have been affected by globalization, in particular colonial expansions of wine producing empires. We study several historic cases and find that (a) planting right restrictions and compulsory uprooting of vineyards are introduced to deal with falling wine prices as colonial wine production takes off and expands; (b) that enforcement of the restrictions and uprooting was difficult and often imperfect; and (c) that there was a strong persistence of the policies: after their introduction the restrictions remain in place for a long time (often centuries) and they are only removed after major shocks to the political economy equilibrium.
