Financially constrained governments, particularly in emerging and developing economies, tend to face a fiscal trade-off between adapting to climate change impacts and pursuing broader development goals. This trade-off is especially relevant in the agriculture sector, where investing in adaptation is critical to ensure food security amidst climate change. International trade can help alleviate this challenge and reduce adaptation investment needs by offsetting agricultural production shortages. However, in the presence of trade fragmentation, the adaptive role of trade diminishes, exacerbating food insecurity and increasing investment needs for adaptation. In this paper, we present a model to guide policymakers in deciding on the cost-efficient balance between investing in adaptation in the agricultural sector versus in broader development under financing and trade constraints. We apply the model to Ghana, Egypt, and Brazil, to examine the adaptation-development trade-off and highlight factors that would potentially lower adaptation investment needs. These factors include trade openness, higher agricultural productivity and efficiency of adaptation spending, and reduced labor market distortions. The key takeaways from the model applications suggest that (i) promoting trade openness and accessing concessional finance for adaptation help tackle climate challenges and ensure food security in lower-income countries; and (ii) domestic structural reforms are necessary to facilitate adaptation investments and reduce investment needs, by improving labor market flexibility, adaptation efficiency, and agriculture productivity.

We propose a macroeconomic model to assess optimal public policy decisions in the the face of competing funding demands for climate change action versus traditional welfare-enhancing capital investment. How to properly delineate the costs and benefits of traditional versus adaption-focused development remains an open question. The paper places particular emphasis on the changing level of risk and vulnerabilities faced by developing countries as they allocate investment toward growth strategies, adapting to climate change and emissions mitigation.

Global investment to achieve the Paris Agreement’s temperature and adaptation goals requires immediate actions—first and foremost—on climate policies. Policies should be accompanied by commensurate financing flows to close the large financing gap globally, and in emerging market and developing economies (EMDEs) in particular. This note discusses potential ways to mobilize domestic and foreign private sector capital in climate finance, as a complement to climate-related policies, by mitigating relevant risks and constraints through public-private partnerships involving multilateral, regional, and national development banks. It also overviews the role the IMF can play in the process.

The Nationally Appropriate Mitigation Action (NAMA) is the new kid on the block in the battle against climate change. The NAMA is the most decisive instrument devised to address the fact that today the only source of growing emissions are the world’s developing countries. But as it is based purely on voluntarism it crucially depends on financing models that can lift the concept off the ground. This book provides the first insights as to how this concept can deliver on its promise – and challenges some of the fundamental mantras in international climate change collaboration.

This book builds on a decade-long experience with mechanisms provided by the Kyoto Protocol and the UN Framework Convention on Climate Change. It discusses the challenges of climate finance in the context of the post-Copenhagen negotiations and provides a long-term outlook of how climate finance in developing countries could develop. Written by climate finance experts from academia, carbon finance businesses and international organisations, the book provides background, firsthand insights, case studies and analysis into the complex subject area of climate finance.

The book will serve as a guide for local governments and private enterprises as they navigate the unchartered waters of investing in climate change adaptation and resilience. Not only does it identify potential funding sources but also presents a roadmap for asset management and public finance processes.

This report identifies ways to overcome key barriers to private sector investment in adaptation and resilience, laying out a coordinated and data-driven Blueprint for Action to help governments and their development partners to close the adaptation finance gap. Although climate adaptation finance flows have increased by 35% in recent years, they still fall short of what is needed to avoid severe economic and human impacts from climate change. The urgent need for boosting investment in climate adaptation and resilience cannot be overstated. Much remains to be learned about how to unlock and enable private capital to help finance national and local adaptation priorities, and how to build the business case for adaptation. The report offers a snapshot of current levels of private financing for climate adaptation and how they fit into global efforts to finance climate resilience-building around the world. It documents the main barriers that have stymied private investment in adaptation to date. The report proposes a blueprint for action--a concrete, stepped approach for governments to address barriers to private investment in adaptation and resilience--so private capital can actively contribute to financing national and local priorities. The blueprint provides five entry points to enable private investment. The Blueprint for action we propose in the report represents a novel coordinated framework for action for governments to develop, finance, and implement priority adaptation and resilience investments - driven by countries' goals and national investment plans that can help accelerate and scale up investment to address the climate resilience needs of the world's most climate-vulnerable communities and economies.
