Abstract:
Rising concern about carbon emissions from deforestation has led donors to finance UN-REDD (Reducing Emissions from Deforestation and Forest Degradation in Developing Countries), a program that offers direct compensation for forest conservation. Sustainable operation of UN-REDD and other direct-compensation programs will require a transparent, credible, frequently updated system for monitoring deforestation. In this paper, we introduce FORMA (Forest Monitoring for Action), a prototype system based on remotely sensed data. We test its accuracy against the best available information on deforestation in Brazil and Indonesia. Our results indicate that publicly available remotely sensed data can support accurate quarterly identification of new deforestation at 1 km spatial resolution. More rapid updates at higher spatial resolution may also be possible. At current resolution, with efficient coding in publicly available software, FORMA should produce global updates on one desktop computer in a few hours. Maps of probable deforestation at 1 km resolution will be accessible with Google Earth and Google Maps, with an open facility for ground-truthing each pixel via photographs and text comments.

22. The Structural Transformation as a Pathway out of Poverty: Analytics, Empirics and Politics

Abstract:
A powerful historical pathway of structural transformation is experienced by all successful developing countries, and this Working Paper presents the results of new empirical analysis of the process. Making sure the poor are connected to both the structural transformation and to the policy initiatives designed to ameliorate the distributional consequences of rapid transformation has turned out to be a major challenge for policy makers over the past half century. There are successes and failures, and the historical record illuminates what works and what does not. Trying to stop the structural transformation does not work, at least for the poor, and in fact can lead to prolonged immiseration. Investing in the capacity of the poor to cope with change and to participate in its benefits through better education and health does seem to work. Such investments typically require significant public sector resources and policy support, and thus depend on political processes that are themselves conditioned by the pressures generated by the structural transformation itself.

23. Biofuels and the Food Price Crisis: A Survey of the Issues

Working Paper

Abstract:
While the precise contribution of biofuels to surging food prices is difficult to know, policies promoting production of the current generation of biofuels are not achieving their stated objectives of increased energy independence or reduced greenhouse gas emissions. Reaching the congressionally mandated goal of blending 15 billion gallons of renewable fuels in gasoline by 2015 would consume roughly 40 percent of the corn crop (based on recent production levels) while replacing just 7 percent of current gasoline consumption. Moreover, while it has long been known that the net energy and greenhouse gas emission benefits of corn-based ethanol are relatively small because its production is energy-intensive, recent scientific studies suggest that the current generation of biofuels, including biodiesel made from palm oil, soybeans, and rapeseed, as well as corn-based ethanol, actually add to greenhouse gas emissions relative to petroleum-based fuels when land use changes are taken into account. That is, greenhouse gases are released when forests are cut down or grasslands cleared to plant biofuels, or food is planted on new acreage to replace crops diverted to fuel elsewhere. In sum, the food crisis adds urgency to the need to change these policies but does not change the basic fact that there is little justification for the current set of policies.

24. Does Digital Divide or Provide? The Impact of Cell Phones on Grain Markets in Niger

Abstract:
Due partly to costly information, price dispersion across markets is common in developed and developing countries. Between 2001 and 2006, cell phone service was phased in throughout Niger, providing an alternative and cheaper search technology to grain traders and other market actors. Weconstruct a novel theoretical model of sequential search, in which traders engage in optimal search for the maximum sales price, net transport costs. The model predicts that cell phones will increase traders' reservation sales prices and the number of markets over which they search, leading to a reduction in price dispersion across markets. To test the predictions of the theoretical model, we use a unique market and trader dataset from Niger that combines data on prices, transport costs, rainfall and grain production with cell phone access and trader behavior. We first exploit the quasi-experimental nature of cell phone coverage to estimate the impact of the introduction of information technology on market performance. The results provide evidence that cell phones reduce grain price dispersion across markets by a minimum of 6.4 percent and reduce intra-annual price variation by 12 percent. Cell phones have a greater impact on price dispersion for market pairs that are farther away, and for those with lower road quality. This effect becomes larger as a higher percentage of markets have cell phone coverage. We provide empirical evidence in support of specific mechanisms that partially explain the impact of cell phones on market performance. Robustness checks suggest that the results are not driven by selection on unobservables, nor are they solely a result of general equilibrium effects. Calculations of the four-firm concentration index suggest that the grain market structure is competitive, so the observed reductions in price dispersion are not due to greater market collusion. The primary mechanism by which cell phones affect market-level outcomes appears to be a reduction in search costs, as grain traders operating in markets with cell phone coverage search over a greater number of markets and sell in more markets. The results suggest that cell phones improved consumer and trader welfare in Niger.

25. Thought for Food: The Challenges of Coping with Soaring Food Prices

Author:
Nora Lustig

Content Type:
Working Paper
Institution:
Center for Global Development
Abstract:
World food commodities prices increased 130 percent from January 2002 to July 2008. Individual agricultural commodities show even more pronounced increases: corn, wheat, rice and soybeans rose by 190, 162, 318 and 246 percent, respectively. Since July, food commodities prices began to fall. While this decline comes as a relief, prices are likely to stay high in the foreseeable future. Available evidence suggests that the decline in living standards of net consumers caused by higher food prices outweighs the benefits accruing to poor net sellers in the majority of countries that have been analyzed so far. The time to implement measures to help the poor net consumers cope with higher food prices is now. However, too many developing countries lack the instruments, administrative capacity and fiscal space to implement safety nets fast enough and in the required scale. This is one of the most pressing policy challenges that we face. For the poor who are net sellers, governments should seize the opportunity to convert the short-run windfall into longer-term gains. Multilateral financial institutions can play a key role in providing financial resources to countries facing negative terms of trade shocks, technical assistance in the design of safety nets and resources to add fiscal space to countries to fund safety net programs. International organizations can also help countries design the appropriate macroeconomic policy response. This will call for greater flexibility in the menu of policy options traditionally deployed by the Bretton Woods institutions.

26. Rainfall Shocks, Markets, and Food Crises: Evidence from the Sahel

Author:

Abstract:
How do markets respond to extreme rainfall in West Africa? This paper examines the effect of weather on grain market performance in Niger, a country increasingly affected by drought and severe food crises over the past two decades. Using a dataset that combines information on rainfall, agricultural production, prices and transaction costs, I exploit rainfall variation to estimate the impact of drought on grain market performance between 1997 and 2006. Time series tests suggest that grain markets in Niger respond to supply shocks and that markets are more integrated during drought years. Exploiting the exogeneity of extreme rainfall in a difference-in-differences framework supports these findings: drought reduces grain price dispersion across markets. This impact is stronger as a higher percentage of markets are affected by drought, as was the case in 2004/2005, the year of a severe food crisis. The results suggest that early warning systems in West Africa should focus on the spatial impact of drought at the sub-regional level, as well as monitor prices in key forecasting markets during the harvest period.

27. Aiding Transparency: What We Can Learn About China Exim Bank's Concessional Loans

Abstract:
The Chinese government, through the China Exim Bank, is pledging billions of dollars worth of concessional lending to the developing world. More information on these lending practices can be gleaned from Chinese language sources than is readily available in English. However, this material is insufficient to draw more than tentative conclusions about the real nature and scope of China's concessional lending. Over 48 countries have agreements with China for concessional loans. An average loan of US$20-30 million is made available to Chinese exporting firms to develop infrastructure and facilities in developing countries. While these loan sizes are not huge when compared to other aid flows, China's status as the dominant lender of concessional loans amongst some recipients makes this program significant. Finally, it is still not clear if the loans could be considered Official Development Assistance according to the DAC definition.
