Human dimensions is a way of thinking Human dimensions is a way of thinking about how we do the science: caring to about how we do the science: caring to know what civil society thinks, what are know what civil society thinks, what are their priorities, what do they do, what their priorities, what do they do, what
do they want to know?do they want to know?

One of the biggest obstacles we face One of the biggest obstacles we face is the traditional division of labor in is the traditional division of labor in doing science, where there is a lack doing science, where there is a lack
of understanding between the of understanding between the natural and the social sciences —we natural and the social sciences —we need to move towards defining the need to move towards defining the
research questions together so they research questions together so they constitute integrative questions constitute integrative questions

For example, we can begin to examine how a For example, we can begin to examine how a change in the price of a commodity (e.g. cacao) change in the price of a commodity (e.g. cacao)

increase area planted), and how this shift in increase area planted), and how this shift in land use affects biogeochemical fluxes (is the land use affects biogeochemical fluxes (is the
shift from forest to cacao, from pasture to shift from forest to cacao, from pasture to cacao, from secondary forest to cacao), and cacao, from secondary forest to cacao), and

incorporate what matters to incorporate what matters to people into what we examine people into what we examine

Putting the parts togetherPutting the parts together• We need to sit together with a real interest in
surpassing our disciplinary biases, • adding respect for the way others think• try to link data • critically deal with how to sample and how to
measure• how to deal with the whole rather than only with
the parts– • this will require humility, learning a lot of different
ways to get at a problem, and to jointly choose the best approach for the question asked.
• Actually working together in the field in one of the best ways…

Aids is not just a direct killer but a major contributor to famine, according to aid agencies. Some countries are expected to lose a quarter of their agricultural workforce to Aids by 2020. Early deaths deprive new generations of vital knowledge about farming methods, while food consumption in families hit by HIV/Aids drops by up to 40%.

What do the local people think?What do the local people think?
• In some locations, they are mobilizing: concerned with what they recognize are changes in local patterns of precipitation
• In the two regions, i.e. Altamira and Santarem, they comment that the rainy season now commonly starts two months later than it did just 25 years ago
• In Santarem, the vulnerability is even greater during ENSO events, when drought increases the vulnerability of forests to burn
• They understand there must be a connection between forest cover and precipitation– and want to create a large protected area to ensure adequate precipitation for their agriculture
