With further rise in global warming, risks associated with climate change events will aggravate and that will add to food and water insecurity. The second part of the latest UN Intergovernmental Panel on Climate Change (IPCC) report has been published. The report indicated the risk of shortage and informed that poor communities are at greater risk to face the insecurity.

In Yokohama, Japan, the report of the IPCC's Fifth Assessment Report (AR5) was released. The report includes impacts, adaptation and vulnerability related with climate change. It also looks into new insights with regard to risks due to climate change.

The second working group that prepared the report said one thing is very clear that we are living in a world where the results of climate change are not only present, but they are widespread and consequential.

The report looked into many changes that climate change has caused, including alteration in rainfall, melting snow and ice pattern and how these changes have affected water resources in many regions. One of the alarming changes is shift in species' migratory range. Scientists warned that the shift poses a big threat to food security.

Report makers have highlighted Asia and think that it will be particularly hardest-hit by the food and water insecurities and redistribution of land species and an increased risk to coastal and marine ecosystems.

South Asia will be the most impacted by global warming and extreme weather events like floods and droughts. One of the biggest reasons for threat in the region is presence of large population of impoverished people.

As per scientists, adaptation can reduce the risks of climate change. But they also affirmed that at the current stage, it is difficult to work out the costs of adaptation measures. "One thing that we have come up with is the importance of adaptation and mitigation choices because this is the only way we might be able to reduce the risks of climate change", said experts.
