Disaster risk reduction in the context of Mapathon

Sustainable Development Goal 11 (SDG 11 or Global Goal 11), titled "sustainable cities and communities", is one of 17 Sustainable Development Goals established by the United Nations General Assembly in 2015. The official mission of SDG 11 is to "Make cities inclusive, safe, resilient and sustainable". The 17 SDGs take into account that action in one area will affect outcomes in other areas as well, and that development must balance social, economic and environmental sustainability.

SDG 11 has 10 targets to be achieved, and this is being measured with 15 indicators. The seven outcome targets include safe and affordable housing, affordable and sustainable transport systems, inclusive and sustainable urbanization, protection of the world's cultural and natural heritage, reduction of the adverse effects of natural disasters, reduction of the environmental impacts of cities and to provide access to safe and inclusive green and public spaces. The three means of implementation targets include strong national and regional development planning, implementing policies for inclusion, resource efficiency, and disaster risk reduction in supporting the least developed countries in sustainable and resilient building.

Emergency management (also disaster management or emergency preparedness) is a science and a system charged with creating the framework within which communities reduce vulnerability to hazards and cope with disasters. Emergency management, despite its name, does not actually focus on the management of emergencies; emergencies can be understood as minor events with limited impacts and are managed through the day-to-day functions of a community. Instead, emergency management focuses on the management of disasters, which are events that produce more impacts than a community can handle on its own. The management of disasters tends to require some combination of activity from individuals and households, organizations, local, and/or higher levels of government. Although many different terminologies exist globally, the activities of emergency management can be generally categorized into preparedness, response, mitigation, and recovery, although other terms such as disaster risk reduction and prevention are also common. The outcome of emergency management is to prevent disasters and where this is not possible, to reduce their harmful impacts.

Nature-based solutions (or nature-based systems, and abbreviated as NBS or NbS) describe the development and use of nature (biodiversity) and natural processes to address diverse socio-environmental issues. These issues include climate change mitigation and adaptation, human security issues such as water security and food security, and disaster risk reduction. The aim is that resilient ecosystems (whether natural, managed, or newly created) provide solutions for the benefit of both societies and biodiversity. The 2019 UN Climate Action Summit highlighted nature-based solutions as an effective method to combat climate change. For example, nature-based systems for climate change adaptation can include natural flood management, restoring natural coastal defences, and providing local cooling.

The concept of NBS is related to the concept of ecological engineering and ecosystem-based adaptation. NBS are also related, conceptually to the practice of ecological restoration. The sustainable management approach is a key aspect of NBS development and implementation.

The Sendai Framework for Disaster Risk Reduction (2015–2030) is an international document adopted by the United Nations (UN) member states in March 2015 at the World Conference on Disaster Risk Reduction held in Sendai, Japan, and endorsed by the UN General Assembly in June 2015. It is the successor agreement to the Hyogo Framework for Action (2005–2015), which had been the most encompassing international accord to date on disaster risk reduction.

The World Conference on Disaster Risk Reduction is a series of United Nations conferences focusing on disaster and climate risk management in the context of sustainable development. The World Conference has been convened three times, with each edition to date having been hosted by Japan: in Yokohama in 1994, in Hyogo in 2005 and in Sendai in 2015. As requested by the UN General Assembly, the United Nations Office for Disaster Risk Reduction (UNDRR) served as the coordinating body for the Second and Third UN World Conference on Disaster Reduction in 2005 and 2015.

The conferences bring together government officials and other stakeholders, such as NGOs, civil society organizations, local government and private sector representatives from around the world to discuss how to strengthen the sustainability of development by managing disaster and climate risks. The Third UN World conference adopted the Sendai Framework for Disaster Risk Reduction 2015–2030. Previous conference outcomes include the Hyogo Framework for Action 2005 – 2015: Building the Resilience of Nations and Communities to Disasters in 2005 and the Yokohama Strategy and Plan of Action for a Safer World in 1994.
