Environment & Climate Change

African agriculture is at a crossroads. Persistent food shortages are now being compounded by new threats arising from climate change. But Africa also has three major opportunities that can help transform its agriculture to be a force for economic growth. First, advances in science, technology, and engineering worldwide offer Africa new tools needed to promote sustainable agriculture. Second, efforts to create regional markets will provide new incentives for agricultural production and trade. Third, a new generation of African leaders is helping the continent focus on long-term economic transformation.

Negotiations under the United Nations Framework Convention on Climate Change (UNFCCC) at Copenhagen in December 2009 did not produce a new international treaty with binding emissions commitments, but have defined a roadmap for dealing with global climate change in the post-2012 era. As countries continue to pursue new models for global agreement, it will be important to learn from the weaknesses of past approaches, while building on positive aspects of the experience with the Kyoto Protocol so far.

An effective international climate agreement poses formidable challenges. Existing agreements, naturally, have some good features. Further improvements are being discussed in the current negotiations. But the cost and uncertainty associated with regular renegotiation of commitments is not being addressed. The São Paulo Proposal suggests mechanisms that would avoid the need for regular renegotiation of commitments and suggests other ways to make international climate agreements more effective.

The Kyoto Protocol uses a top-down mechanism to negotiate economy-wide emissions caps. This paper proposes an alternative "sectoral" approach, which would determine industry-level emissions reduction targets based on technological analyses.

Although an effective solution to the climate change problem will require the cooperation of the developing countries, it is not clear that near-term greenhouse gas emission quotas from these countries are either feasible or desirable. This paper argues that a post-2012 international climate agreement should instead focus on creating incentives to stimulate research and development of new climate-friendly technologies.

This paper proposes a fair and efficient climate change policy architecture for the post-2012 era. It focuses on how to break the current political impasse between the developed and the developing countries. The architecture is a multi-stage framework that gradually engages developing countries.

Policies facilitating innovation and large-scale adoption of low-carbon technologies will need to play a central role in global efforts to address climate change, alongside policies targeted directly at reducing emissions.  This paper considers opportunities for improved and expanded international technology development and transfer strategies within the broader context of international agreements and institutions for climate, energy, trade, development, and intellectual property.
