He has led strategic programme reviews and project identification missions for the EC and Norway, and advised private corporations on carbon conservation and biodiversity investment opportunities, and on environmental change and investment risks.

He has given keynote speeches on environmental sustainability at several international public and private sector conferences, and as a prolific writer and experienced editor he has authored studies for UNEP on disaster risk reduction and environmental policies, laws and treaties, while also publishing his own books through the Cambridge and California university presses, and the World Bank and other institutions, on subjects ranging from water, biodiversity and ecosystem conservation, to good governance, poverty and development cooperation (see https://orcid.org/0000-0002-9261-5912).
