More than ever, the health and prosperity of individuals, communities, and nations are deeply intertwined with the natural ecosystems that sustain them. The great challenge of this century is to meet the growing demand for food, fresh water, energy, and other resources that advance human development while protecting our ecosystems. Meeting this challenge requires finding solutions at the intersection of human and natural systems. Our work — with businesses, governments, foundations, and non-profits — recognizes the interdependency of human progress and the environment to protect the world’s most vulnerable people and ecosystems. Our expertise includes strategy and policy design, partnership building and creation of financing models. 

Developing the Field of Planetary Health

We worked with the Rockefeller Foundation to develop a new approach to addressing global human health challenges by understanding the underlying environmental foundations for health. We then identified specific entry points for investment. This new approach - Planetary Health - seeks to uncover new solutions to entrenched as well as emerging health challenges in developed and developing countries.

Supporting Sustainable Fisheries


Making small-scale fisheries sustainable is an urgent ecological, economic and social challenge.

Ocean fisheries are one of our most important and resilient resources, yet they are in crisis. Nearly 40% of fisheries have collapsed or are overexploited, risking the livelihoods and food security of billions of people and pressuring countless species in the world’s most bio-diverse waters.

The State of the Off-Grid Appliance Market

The global off-grid appliance market is critical for increasing access to electricity and services. Over two billion people worldwide lack access to reliable electricity. Renewable energy technologies, especially solar, are helping bridge this gap. Signs of success already exist in the fast-growing Solar Portable Lamps (SPLs)
and Solar Home System (SHS) product market.

Protecting People Through Nature

Natural world heritage sites provide important economic, social and environmental benefits to people. these sites are recognized internationally for their outstanding universal value as places with “significance which is so exceptional as to transcend national boundaries and to be of common importance for present and future generations of all humanity.” 

Protecting Tigers from Asia’s Infrastructure Development Boom

This blog draws on findings from a new report from Dalberg and WWF — Protecting Tigers from Asia’s Infrastructure Development Boom.

Tigers have travelled a rocky road over the past hundred years. Decimated from rampant poaching and merciless habitat destruction, the tiger population fell from over 100,000 at the start of the 20th century to just 3,200 in 2010. This rocky road is fast approaching a cliff edge.
