Livestock policy

Livestock interact with sustainable development in positive and negative ways. We provide a balanced view on livestock policy for people and planet.

Land use trends

We review the three centuries of global agricultural land use trends and their impacts on environmental health and food security.

The Colours of Food Security

The Colours of Food Security is an online exhibit that takes you on a journey through the food system today. Co-created with the LUGE lab.

LiteFarm

I founded LiteFarm, the world’s first digital platform for participatory assessment of social, environmental and economic outputs of farming systems.

Small farms

Here we show that while small farms only make up around 25% of the world's agricultural land they produce a third of the world's food.

Water scarcity

We are systematically mapping evidence based solutions for water scarcity with Ceres2030. Sustainable solutions for ending hunger.

Baselines for Data Driven Farming

I led the team who developed the world's first ever baselines for data driven farming interventions with global reach. Informing tech for the future.

Breadbasket failure

With a growing population, volatile markets, biodiversity loss, and natural disasters, people are worried about food system collapse. Should we be?

Half-Earth

Half Earth is a recent proposal from conservation leaders calling humanity to give half of the planet back to nature. Is it possible?

The cost of natural disasters

We estimate the farm gate cost of heat waves and droughts over 1961-2014 to be 237 billion USD (2005 constant dollars).

Coffee forests

Global demand for coffee is constantly rising while the security of its production is increasingly threatened by disease and a changing climate. Is its site of origin able to provide solutions to these challenges?

Diversity

We need to increase diversity in our food systems. I set up the Diversified Agro-ecosystems Research Cluster with Hannah Wittman at UBC, to work out how to do exactly that.

Alternatives

We need new ways of farming that are better for the people and planet, but do they carry trade-offs?

IPBES

I was one of 500+ contributing authors to the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services first Global Assessment. Read the summary report here.
