Risk management is the identification, evaluation, and prioritization of risks followed by coordinated and economical application of resources to minimize, monitor, and control the probability or impact of unfortunate events or to maximize the realization of opportunities.
The economic analysis of climate change explains how economic thinking, tools and techniques are applied to calculate the magnitude and distribution of damage caused by climate change. It also informs the policies and approaches for mitigation and adaptation to climate change from global to household scales. This topic is also inclusive of alternative economic approaches, including ecological economics and degrowth. In a cost–benefit analysis, the trade offs between climate change impacts, adaptation, and mitigation are made explicit. Cost–benefit analyses of climate change are produced using integrated assessment models (IAMs), which incorporate aspects of the natural, social, and economic sciences. The total economic impacts from climate change are difficult to estimate, but increase for higher temperature changes.
Climate change adaptation is the process of adjusting to the effects of climate change. These can be both current or expected impacts. Adaptation aims to moderate or avoid harm for people. It also aims to exploit opportunities. Humans may also intervene to help adjustment for natural systems. There are many adaptation strategies or options. They can help manage impacts and risks to people and nature. Adaptation actions can be classified in four ways: infrastructural and technological; institutional; behavioural and cultural; and nature-based options.
Disaster risk reduction (DRR) is a systematic approach to identifying, assessing and reducing the risks of disaster. It aims to promote sustainable development by increasing the resilience of communities to any disasters they might face. DRR is normally used as policies intended to "define goals and objectives across different timescales and with concrete targets, indicators and time frames." The concept is also called disaster risk management (DRM).
Climate risk is the potential for negative consequences for human or ecological systems from the impacts of climate change. It refers to risk assessments based on formal analysis of the consequences, likelihoods and responses to these impacts and how societal constraints shape adaptation options. However, the science also recognises different values and preferences around risk, and the importance of risk perception.
The Weather Info for All (WIFA) Initiative is a public-private partnership that works to reinforce the capacities and the capabilities of national meteorological services with the goal of supporting local communities worst impacted by climate change through the improvement of weather monitoring. "By bringing together the expertise and resources of different public and private actors, this project may help to save lives and improve the livelihoods of communities in Africa living on the frontlines of climate change." Kofi Annan, President of the Global Humanitarian Forum. The Forum, together with Ericsson, the World Meteorological Organization, National Meteorological Services (NMSs), the Earth Institute at Columbia University, as well as Zain and other mobile phone operators aim to deploy up to 5,000 automatic weather stations (AWSs) at wireless network sites across Africa, where less than 300 are reporting today.
Climate change is a critical issue in Bangladesh as the country is one of the most vulnerable to the effects of climate change. In the 2020 edition of Germanwatch's Climate Risk Index, it ranked seventh in the list of countries most affected by climate calamities during the period 1999–2018. Bangladesh's vulnerability to the effects of climate change is due to a combination of geographical factors, such as its flat, low-lying, and delta-exposed topography, and socio-economic factors, including its high population density, levels of poverty, and dependence on agriculture. The impacts and potential threats include sea level rise, temperature rise, food crises, droughts, floods, and cyclones.
Climate change in Africa is an increasingly serious threat as Africa is among the most vulnerable continents to the effects of climate change. Some sources even classify Africa as "the most vulnerable continent on Earth". This vulnerability is driven by a range of factors that include weak adaptive capacity, high dependence on ecosystem goods for livelihoods, and less developed agricultural production systems. The risks of climate change on agricultural production, food security, water resources and ecosystem services will likely have increasingly severe consequences on lives and sustainable development prospects in Africa. With high confidence, it was projected by the IPCC in 2007 that in many African countries and regions, agricultural production and food security would probably be severely compromised by climate change and climate variability. Managing this risk requires an integration of mitigation and adaptation strategies in the management of ecosystem goods and services, and the agriculture production systems in Africa.
The United Nations Office for Disaster Risk Reduction (UNDRR) was created in December 1999 to ensure the implementation of the International Strategy for Disaster Reduction.
The Climate and Development Knowledge Network (CDKN) works to enhance the quality of life for the poorest and most vulnerable to climate change. CDKN does this by combining research, advisory services and knowledge management in support of locally owned and managed policy processes. It works in partnership with decision-makers in the public, private and non-governmental sectors nationally, regionally and globally.
Globally, Nepal is ranked fourth in terms of vulnerability to climate change. Floods spread across the foothills of the Himalayas and bring landslides, leaving tens of thousands of houses and vast areas of farmland and roads destroyed. In the 2020 edition of Germanwatch's Climate Risk Index, it was judged to be the ninth hardest-hit nation by climate calamities during the period 1999 to 2018. Nepal is a least developed country, with 28.6 percent of the population living in multidimensional poverty. Analysis of trends from 1971 to 2014 by the Department of Hydrology and Meteorology (DHM) shows that the average annual maximum temperature has been increasing by 0.056 °C per year. Precipitation extremes are found to be increasing. A national-level survey on the perception-based survey on climate change reported that locals accurately perceived the shifts in temperature but their perceptions of precipitation change did not converge with the instrumental records. Data reveals that more than 80 percent of property loss due to disasters is attributable to climate hazards, particularly water-related events such as floods, landslides and glacial lake outburst floods (GLOFs).
Climate change affects men and women differently. Climate change and gender examines how men and women access and use resources that are impacted by climate change and how they experience the resulting impacts. It examines how gender roles and cultural norms influence the ability of men and women to respond to climate change, and how women's and men's roles can be better integrated into climate change adaptation and mitigation strategies. It also considers how climate change intersects with other gender-related challenges, such as poverty, access to resources, and unequal power dynamics. Ultimately, the goal of this research is to ensure that climate change policies and initiatives are equitable, and that both women and men benefit from them. Climate change increases gender inequality, reduces women's ability to be financially independent, and has an overall negative impact on the social and political rights of women, especially in economies that are heavily based on agriculture. In many cases, gender inequality means that women are more vulnerable to the negative effects of climate change. This is due to gender roles, particularly in the developing world, which means that women are often dependent on the natural environment for subsistence and income. By further limiting women's already constrained access to physical, social, political, and fiscal resources, climate change often burdens women more than men and can magnify existing gender inequality.
Climate resilience is defined as the "capacity of social, economic and ecosystems to cope with a hazardous event or trend or disturbance". This is done by "responding or reorganising in ways that maintain their essential function, identity and structure while also maintaining the capacity for adaptation, learning and transformation". The key focus of increasing climate resilience is to reduce the climate vulnerability that communities, states, and countries currently have with regards to the many effects of climate change. Efforts to build climate resilience encompass social, economic, technological, and political strategies that are being implemented at all scales of society. From local community action to global treaties, addressing climate resilience is becoming a priority, although it could be argued that a significant amount of the theory has yet to be translated into practice.
The contributions of women in climate change have received increasing attention in the early 21st century. Feedback from women and the issues faced by women have been described as "imperative" by the United Nations and "critical" by the Population Reference Bureau. A report by the World Health Organization concluded that incorporating gender-based analysis would "provide more effective climate change mitigation and adaptation."
The Sendai Framework for Disaster Risk Reduction (2015–2030) is an international document that was adopted by the United Nations (UN) member states between 14 and 18 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.
Ecosystem-based adaptation (EBA) encompasses a broad set of approaches to adapt to climate change. They all involve the management of ecosystems and their services to reduce the vulnerability of human communities to the impacts of climate change. The Convention on Biological Diversity defines EBA as "the use of biodiversity and ecosystem services as part of an overall adaptation strategy to help people to adapt to the adverse effects of climate change".
Sustainable Development Goal 13 is to limit and adapt to climate change. It is one of 17 Sustainable Development Goals established by the United Nations General Assembly in 2015. The official mission statement of this goal is to "Take urgent action to combat climate change and its impacts". SDG 13 and SDG 7 on clean energy are closely related and complementary.
Sustainable Development 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.
Climate change disproportionately affects individuals with disabilities, both directly and indirectly. Individuals with disabilities are more likely to experience the effects of climate change on humans more acutely compared to those without disabilities. Typically, disabled people are the most likely to be negatively affected by any form of emergency, whether it be an immediate emergency like a flood or tornado or a gradual emergency like rising sea levels, due to a lack of access to emergency resources and the difficulties imposed by limited mobility. Disabled people are also more adversely affected by climate change because a disproportionate number of disabled people live in poverty, and people living in poverty are inherently more at risk due to climate change. Despite this, and despite the fact that disabled people make up more than 15% of the global population, they have had minimal input and involvement in the decision-making process surrounding responses to climate change. A 2022 study by the Disability-Inclusive Climate Action Research Programme revealed that only 37 of 192 State Parties to the Paris Agreement currently refer to persons with disabilities in their nationally determined contributions, while only 46 State Parties refer to persons with disabilities in their domestic climate adaptation policies.
Climate change adaptation in the Philippines is being incorporated into development plans and policies that specifically target national and local climate vulnerabilities. As a developing country and an archipelago, the Philippines is particularly vulnerable to a variety of climatic threats like intensifying tropical cyclones, drastic changes in rainfall patterns, rising sea levels, and rising temperatures. According to the UN Office for the Coordination of Humanitarian Affairs (OCHA), the Philippines is one of the most disaster-prone countries in the world. In 2021, the Global Climate Risk Index ranked the Philippines fourth of the ten countries most affected between the years 2000 and 2019. The need for managing climate risks through climate change adaptation has become increasingly evident. Adaptation can reduce, moderate or avoid current and expected climate effects or take advantage of beneficial climatic events. Developing greater resilience to various threats can be a major goal of comprehensive disaster risk reduction strategy. The Philippines is therefore working on a number of national and local adaptation and disaster risk reduction strategies to build the country's climate resilience.
