Denmark has a highly ambitious goal of reducing greenhouse gas emissions 70 percent below 1990 levels by 2030. While there is general agreement that carbon pricing should be the centerpiece of Denmark’s mitigation strategy, pricing needs to be effective, address equity and leakage concerns, and be reinforced by additional measures at the sectoral level. The strategy Denmark develops can be a good prototype for others to follow. This paper discusses mechanisms to scale up domestic carbon pricing, compensate households, and possibly combine pricing with a border carbon adjustment. It also recommends the use of revenue-neutral feebate schemes to strengthen mitigation incentives, particularly for transportation and agriculture, fisheries and forestry, though these schemes could also be applied more widely.
Recent micro level data from East Africa is used to benchmark aggregate data and assess the role of agricultural inputs in explaining variation in crop yields on smallholding plots. Fertilizer, improved seeds, protection against erosion and pesticides improve crop yields in Rwanda and Ethiopia, but not Uganda, possibly associated with lack of use there. With all positive yield determinants in place, wheat and maize yields could increase fourfold. The data hints at the negative effect of climate change on yields and the benefits of accompanying measures to mitigate its adverse impact (access to finance and protection against erosion). The adverse effect of crop damage on yields varies between 12/13 percent (Rwanda, Uganda) to 36 percent (Ethiopia). Protection against erosion and investment financing mitigate these effects considerably.
Economic growth in sub-Saharan Africa this year is set to drop to its lowest level in more than 20 years, reflecting the adverse external environment, and a lackluster policy response in many countries. However, the aggregate picture is one of multispeed growth: while most of non-resource-intensive countries—half of the countries in the region—continue to perform well, as they benefit from lower oil prices, an improved business environment, and continued strong infrastructure investment, most commodity exporters are under severe economic strains. This is particularly the case for oil exporters whose near-term prospects have worsened significantly in recent months. Sub-Saharan Africa remains a region of immense economic potential, but policy adjustment in the hardest-hit countries needs to be enacted promptly to allow for a growth rebound.
