International Comparisons of the Modeled
Climate Effects of Land Use Changes
Yingzhi Lin, Fan Zhang, Yi Qu, Zhihui Li and Tao Zhang
Previous chapters focus on the climate effects responding to different types of land
use changes in China. This chapter furthers the researches on the land use impacts
on climate from a global perspective. Five distinguished cases for estimating the
impacts of land surface changes on climate through the world are introduced
separately. The first one still focuses on the possible impacts of underlying cul-
tivated land reclamation on the future climate change, but we move the study area
to India where land reclamation became the dominated land conversion comparing
with other economies. Specifically, the future cultivated land reclamation is pro-
jected for the climate model's performance to estimate the potential effects on
local energy flux and temperature in summer and winter.
Further, global deforestation plays a vital role in regulating climate through
biogeophysical and biogeochemical effects (Bonan
2008
). Currently, deforestation
is one of the typical land cover changes, and its impacts on climate are not the
same at different scales. Tropical deforestation will induce lower evaporate rates
and make the local climate drier and warmer (Costa and Foley
2000
). However,
the boreal forests will change the climate in different ways in comparison with
other forests. In order to understand the biogeophysical effects of different forests
change on the climate, the European Russia boreal forest region is firstly chosen as
the study area to study the regional temperature variation induced by future boreal
deforestation. Besides, the tropical forest in Brazilian Amazon is also considered
to model the potential climatological variability caused by future forest vulnera-
bility over the twenty-first century.
