Tanzania is already experiencing adverse impacts of climate change. Current climate
variability and change resulting in extreme weather events already lead to major economic
costs in Tanzania. Every annual event has economic costs in excess of 1% of GDP, and
occurs frequently, reducing long-term growth and affecting millions of people and their
livelihoods. The net economic costs of addressing climate change impacts could be
equivalent to a further 1 to 2% of GDP per year by 2030. Climate change impacts are
affecting coastal zones, public health, energy supply and demand, infrastructure, water
resources, agricultural production and availability of ecosystem goods and services.
Potentially, there will be high economic costs across these sectors. Current climate
vulnerability and future climate change adverse impacts are significant to curtail Tanzania
from achieving key economic growth, development and poverty reduction targets for
reaching middle income developing country status.
