Of the challenges facing the Earth over the next century, the understanding
of land-use and land-cover change is likely to be the most significant.
This anthropogenic process affects many parts of the earths
system (e.g., climate, hydrology), global biodiversity, and the
fundamental sustainability of lands. Various estimates indicate
that 50 percent of the ice-free land surface has been affected or
modified in some way by human activity while a large fraction of
the global net primary productivity has been captured by human land
use activities. Over the next century, global population is projected
to increase by 50-100% and it is likely that there will also be
an increase in the global standard of living. Thus pressures to
further convert or manage natural ecosystems for human
needs as well as capturing more of the global net primary productivity
are also likely to increase.
The Land Use Land Cover Change Research Group at Brown University
seeks to address problems in this critical area through interdisciplinary
research activities. Our goals are to understand how land cover
and land use is changing, how it changed in the past, and what are
the principal drivers of change. We put current land use and land
cover in the context of its land use history. We are also interested
in the impacts of land use and cover change on natural systems,
as well as reverse feedbacks. This effort is allied with Browns
Environmental Change Initiative and involves participation from
diverse disciplines.
