Statelessness is the condition of being without a nationality. This can occur for a variety of reasons, such as being born in a country that does not recognize birthright citizenship, or being stripped of one's nationality by a government.

According to the United Nations High Commissioner for Refugees (UNHCR), there are an estimated 15 million stateless people in the world.

Statelessness can be caused by a variety of factors, including discrimination, war and conflict, natural disasters, and changes in borders.

Climate change can contribute to statelessness in a number of ways. It can cause natural disasters that displace people from their homes, it can lead to conflict and violence, which can also displace people, and it can make it difficult for people to obtain or maintain citizenship.

Stateless people are often denied basic rights and services, such as education, healthcare, and social security. They are also often at risk of exploitation and abuse, and they may be unable to travel or work legally.

There are a number of things that can be done to address the problem of statelessness. States can adopt laws and policies that prevent and reduce statelessness, they can provide stateless people with access to basic rights and services, and they can work together to find solutions to the problem of statelessness.

The UNHCR is responsible for protecting and assisting stateless people, working to prevent and reduce statelessness, and promoting the rights of stateless people.

The 1954 Convention relating to the Status of Stateless Persons is a treaty that sets out the rights and responsibilities of stateless people. It also provides for the protection of stateless people from discrimination.

The 1961 Convention on the Reduction of Statelessness is a treaty that sets out measures to prevent and reduce statelessness. It also provides for the protection of stateless people from discrimination.

The Global Action Plan to End Statelessness is a plan to end statelessness by 2024. It was adopted by the United Nations General Assembly in 2014.

Some progress has been made in implementing the Global Action Plan to End Statelessness, but more needs to be done. As of 2022, there are still an estimated 15 million stateless people in the world.

There are a number of challenges to ending statelessness, including discrimination, war and conflict, natural disasters, and the lack of political will to address the problem.

There are a number of things that individuals can do to help end statelessness, including learning about statelessness and raising awareness of the issue, supporting organizations that are working to end statelessness, and advocating for policies that prevent and reduce statelessness.

It is likely that statelessness will be reduced significantly in the future, but it is unlikely that it will be completely eliminated. This is because there are a number of challenges to ending statelessness, including discrimination, war and conflict, natural disasters, and the lack of political will to address the problem.
