Climate
change will imperil food supply in Asia
According to researchers climate
change will drastically reduce the flow of snow and ice melt
water in the Himalayas, threatening the food security of more
than 60 million Asians. The major rivers of India and the
Indus and Brahmaputra basins are expected to be the most
adversely affected, while in China the availability of
irrigation water in the Yellow River basin will actually
increase. More than one billion people depend on the meltwater
supplied by the Indus, Ganges, Brahmaputra, Yangtze and the
Yellow River. The downstream sections of the Indus river are
dry and are home to one of the largest irrigation networks in
the world and completely dependent on meltwater. The snow and
ice reserves situated upstream are important for sustaining
the availability of water downstream. Climate change will
ultimately result in declining discharge levels in the major
Asian rivers, impacting the volume of irrigation water
available. However, the opposite is also possible in the
Yellow River basin as an increase in winter rainfall is
expected, resulting in the increased availability of water
early in the growing season. The size and discharge of
Himalayan glaciers are also experiencing significant decline
due to climate change.
Agriculture and UNFCCC post-2012
agreements
The agriculture and rural
development community now needs to build on the momentum
generated in 2009. The overall goal should be to determine how
agriculture can contribute to food security and secured
livelihoods, while simultaneously building resilience to
climate change, reducing GHG emissions and sequestering
carbon. For the coming year it is important to start to put in
place policies and investments to achieve these aims in a way
that places low carbon development and peoples’ livelihoods at
the core of agriculture. This will need to be paired with an
overall increase in investment on agriculture and food
security. Globally securing text under the common vision for
Long Term Co-operative Action (LCA) explicitly mentions food
security and agriculture so that actions developed under the
agreement contribute to this vision. The agreement on an
agriculture work programme under the SBSTA that covers
mitigation and adaptation, which recognises needs of
developing countries and smallholder farmers, is needed. The
development of the LULUCF inventory of emissions and rules
that explicitly include agriculture and support the
development of REDD+ and increase understanding on role of
agriculture as a driver of deforestation and the possibility
of moving to REDD++ is also an important procedure that need
to be considered.
New atlas underlines significant role of
northern soils in climate change
A soil atlas of the world's
northernmost regions was launched at the European Parliament,
where more than half the carbon present in the earth's soils
is stored. It covers regions above the latitude of 50° N,
which represent 16% of global land surface. So far, the public
focus is on the melting of arctic ice as one of the indicators
of climate change. However, 1700 billion tons of organic
carbons are stored in the soils of the northern permafrost
region and their thawing could lead to a substantial release
of greenhouse gases into the atmosphere and would further
increase global warming. The soil atlas of the northern
circumpolar region is the first compilation providing all the
available information on this carbon pool as well as other
important data on northern soils. The atlas will therefore
provide a valuable scientific input to climate change and
sustainable development models. Máire Geoghegan-Quinn, the
European Commissioner for Research, Innovation and Science
said: "This atlas is a unique source of information for
researchers, policy makers, teachers and the general public on
the characteristics of northern soil and raises awareness of
its environmental importance and global significance. It shows
the possible impacts of climate change on permafrost-affected
soils and explains the critical role that they play in the
global climate and carbon cycles."
