His recent experience includes:

  • Developing hydro-economic models to estimate the economic impacts of climate change in river basins and the costs and benefits of structural and non-structural measures to adapt to climate change. 
  • Developing and implementing a framework for defining and measuring the economic impacts of climate change and the costs and benefits of adapting to climate change.
  • Developing models to evaluate the costs and market impacts of policies to promote carbon sequestration on agricultural and timberland.
  • Developing hydro-economic models to estimate the economic impacts of climate change and the benefits and costs of measures to adapt to climate change in river basins.

International experience



2009-2011    Economic Impacts of Climate Change in Macedonia, Montenegro and Moldova

Client:  UNDP Country Offices, Montenegro and Moldova

Dr. Callaway prepared reports for UNDP Macedonia and Montenegro to estimate the economic impacts of climate change on human health and in the agricultural, forestry, tourism, water resources sectors of these countries. The studies characterize the existing analytical capacity to conduct economic impact studies of climate change in the country and present alternatives for improving not only the analytical capacity, but also the institutional capacity to use this information to formulate development and climate policy.  The Macedonia study was unique in that it involved the preparation of sector-level case studies by in-country experts, under Dr. Callaway’s guidance, using available models and data. Dr. Callaway also assisted local contractors in Moldova to improve the country’s first national communication by including estimates of the economic impacts of climate change on the agricultural and water resources sectors.

2007 - 2012   Managing Climate Risk for Agriculture and Water Resources Development in  South-western South Africa

Client: CCAA (Canada and UK)

Dr. Callaway was a member of a team that was awarded a contract to expand the coverage of an earlier Hydro-economic model for the Berg River (BRDSEM) to the larger Cape Winelands (Boland) region.  The new model is called BOLDSEM.The team is comprised of the University of the Free State, Cape Town University, University of KwaZulu-Natal, International Research Institute for Climate and Society and the UNEP-RISØ Center.  Dr. Callaway’s role was to develop the dynamic, spatial equilibrium component of the model and to train African researchers how to further enhance BOLDSEM and how to develop models similar to it for other river basins in South Africa.  The model has been used to simulate the economic impacts of climate change for a number of different climate-driven hydrologic scenarios and to estimate the economic impacts and benefits and costs of reducing economic losses caused by climate change by various investment and management options at the farm level. 

2006 – 2012:  Advisory Board for EU PESETA and PESETA II Projects and for EU CLIMATE COST and PESETA II

Client: EU

Dr. Callaway served on the advisory board for the PESETA (Projection of Economic impacts of climate change in Sectors of the European Union based on boTtom-up Analysis) project and is now performing the same function for the PESETA II project.  The purpose of these projects is to provide quantitative estimates for the economic value of the climate change damages in the following sectors: coastal systems, energy demand, human health, agriculture, tourism and flooding.  He was brought onto the advisory board to provide guidance about estimating the benefits and costs of adapting to climate change in these sectors.  The Project CLIMATE COST is a continuation of the PASETA, designed to improve on the sector coverage, databases, and methodologies used in the previous study.

2007 – 2008 Expert Advisor on Adaptation to World Bank Advisory Committee on Climate  Change

Client:   World Bank Latin America and the Caribbean Region

Every year the Latin America and the Caribbean Region of the World Bank prepares a "flagship" report on a topic of particular interest to the policy makers in the region. The flagship report receives high-profile dissemination throughout the region and often is influential in the policies and investments of the World Bank and its client countries.  The 2008 report will examine both the role that the region can play to mitigate green house gases emissions and how it can cope with the adverse impacts of climate in the face of rapid economic development and growing equity concerns in the region.  Dr. Callaway was a member of the Advisory Committee for this report and helped review comment upon the flagship report at several stages in its preparation.

2008 – 2011 CCTAME Project

Client:  EU ENV

Dr. Callaway was a principle investigator on this project, under the leadership of Institute for International Applied Systems Analysis (IIASA).  He was responsible for helping to debug and verify the EUFASOM land use model. He will also add a water resources sector to the model so that it can better simulate irrigated agricultural production as well the processing of biofuels.  Finally, he is responsible for developing the experimental design to isolate the partial and interaction effects of mitigation of greenhouse gases by and adaptation to climate change within the agricultural and forest sectors in the EU.

2008 – 2009 Human Development Report, Croatia

Client: UNDP, Croatia

Dr. Callaway was an external consultant to UNDP Croatia, helping this entity to prepare a human development report on Climate Change. The report focused on the monetization of climate change damages and the benefits and costs of policies and projects to adapt to climate change and on the capacity required to improve the ability to make these calculations.  Dr. Callaway worked with a team Croatian physical scientists.  Jointly, they evaluated the existing capacity of Croatian scientists and economists to undertake an integrated assessment of climate change impacts and adaptation and they also prepared some case studies to illustrate not only how to value the damages of climate change and the benefits and costs of adapting to climate change, but also how important it is to “fill in” missing gaps in data bases and models for the country.  The results of this work are published in the UNDP Human Development Report for Croatia, A Climate for Change.2005-2006       

2005-2006 Support to African Ministers on Hydropower Development

Client: UNEP

For a year, Dr. Callaway assisted UNEP by providing technical and policy support to the African Ministerial Conference on the subject of Hydropower development.  The focus of Dr. Callaway’s efforts has been to develop policy and valuation frameworks for incorporating the effects of climate change into estimates of African hydropower potential and dam planning.

2003-2006    AICCC Project: Estimating Benefits and Costs of Adaptation Projects in The   Gambia and South Africa

Client:  UNEP, GEF

Dr. Callaway provided technical assistance to researchers in The Gambia and South Africa to develop and implement models to estimate the costs and benefits of measures to adapt to climate change.  In The Gambia, the project focused on using the value of food aid displaced as a proxy measure for the benefits of introducing widespread use of irrigation in the country to offset more frequent droughts in climate change.  For the South African case study, Dr. Callaway was the primary developer of a hydro-economic model, called BRDSEM (Berg River Dynamic Spatial Equilibrium Model) that was used to estimate and compare the benefits and costs of avoiding climate change damages by increasing storage capacity in the Berg River basin and/or through the implementation of water markets.  It was one of the first studies of its kind to estimate the incremental net benefits of coping with both development pressure and climate change, and a major finding of this project was that instituting a system of water markets to respond to both development and climate change was a true no-regrets measure that made basin both better able to cope with increased competition for water and less vulnerable to climate change damages.

2000-2003        Technical Assistance to LDCs for NAPA Preparation


Dr. Callaway developed training materials, held training sessions at three workshops, and visited four developing countries (The Gambia, Mali, Senegal and Chad) to assist government staff to develop their National Adaptation Plans of Action.  The focus of the training, funded by UNEP, was on developing the capacity of the governments in the LDC group to estimate the benefits and costs of projects to reduce climate change damages and to integrate non-market valuation of environmental impacts into these assessments.

1998-2000    Implementation of the Clean Development Mechanism (CDM) in Developing Countries

Client:   Danida and UNEP

Dr. Callaway managed a project for Danida and UNEP to develop the capacity of four African countries (Zimbabwe, Uganda, The Gambia, and Ghana) to assess and implement projects under the Clean Development Mechanism, an “open” emissions trading system between developed and developing nations. The study teams in each country are examining how selected projects would be accredited, implemented, and financed under different hypothetical CDM arrangements, including private sector, country-to-country and multi-lateral CDM arrangements.  The study teams are also exploring how their governments wouldorganiseto participate in the CDM.

1997-  1998  Adaptation Costs

Client: IPCC/UNEP/Danida

Dr. Callaway acted as lead author in writing the chapter on adaptation costs for the forthcoming IPCC/UNEP publication, Mitigation and Adaptation Cost Assessment: Concepts, Methods and Appropriate Use.  The paper developed a framework for estimating adaptation costs that is consistent both for “structural” adaptation measures, such as building dikes, and behavioral adaptation which involves all forms of resource re-allocation by consumers, producers and factor owners. The material in this publication was presented at an IPCC Workshop on Adaptation and Mitigation Costs, held in Roskilde in June of 1997, and later published by UNEP.

1996-1998        Economics of Greenhouse Gas Limitations – Forest and Agricultural Sectors

 Client: Global Environmental Facility

Dr. Callaway participated in a study to assess the greenhouse gas mitigation (GHG) potential and incremental costs in Argentina, Ecuador, Mauritius, Senegal, Vietnam, Indonesia, Estonia and Hungary.  He assisted in the development of methodological guidelines for estimating GHG reductions and incremental costs in the forest and agricultural sectors, and provided technical assistance in implementing the methodology in several of the countries.  He also developed a dynamic inventory model for Tanzania to calculate carbon sequestration costs. In addition, he contributed to chapters on the transport sector and the use of policy instruments.
