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. We can classify adaptation actions in four ways. These are infrastructural and technological; institutional; behavioural and cultural; and nature-based options.
C40 Cities Climate Leadership Group is a group of 96 cities around the world that represents one twelfth of the world's population and one quarter of the global economy. Created and led by cities, C40 is focused on fighting the climate crisis and driving urban action that reduces greenhouse gas emissions and climate risks, while increasing the health, wellbeing and economic opportunities of urban residents.
In Nepal, the economy is dominated by agriculture. In the late 1980s, it was the livelihood for more than 90% of the population, although only approximately 20% of the total land area was cultivable, it accounted for, on average, about 60% of the GDP and approximately 75% of exports. Since the formulation of the Fifth Five-Year Plan (1975–80), agriculture has been the highest priority because economic growth was dependent on both increasing the productivity of existing crops and diversifying the agricultural base for use as industrial inputs.
Urban resilience has conventionally been defined as the "measurable ability of any urban system, with its inhabitants, to maintain continuity through all shocks and stresses, while positively adapting and transforming towards sustainability".
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.
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).
In the fields of engineering and construction, resilience is the ability to absorb or avoid damage without suffering complete failure and is an objective of design, maintenance and restoration for buildings and infrastructure, as well as communities. A more comprehensive definition is that it is the ability to respond, absorb, and adapt to, as well as recover in a disruptive event. A resilient structure/system/community is expected to be able to resist to an extreme event with minimal damages and functionality disruptions during the event; after the event, it should be able to rapidly recovery its functionality similar to or even better than the pre-event level.
The C40 Cities Climate Leadership Group’s Climate Positive Development Program (Climate Positive) was launched in May 2009 in partnership with the Clinton Climate Initiative and the U.S. Green Building Council. The program brings together leading district-scale new-build and regeneration projects working to achieve "Climate Positive"—or net carbon negative—outcomes in cities around the world. As part of the C40’s Sustainable Communities Initiative, it aims to create a model for large-scale urban communities and to support projects that serve as urban laboratories for cities seeking to grow in ways that are environmentally sustainable, climate resilient, and economically viable.
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 Global Climate Action Partnership (GCAP), formerly the Low Emissions Development Strategies Global Partnership, aims to advance climate-resilient low emission development and support transitions to a low-carbon economy through coordination, information exchange and cooperation among countries and programs working to advance low-emission economic growth. The partnership was launched in 2011 and brings together more than 160 governmental and international institutions. The implementation, knowledge management, and outreach of LEDS GP is coordinated by a co-secretariat of the Climate & Development Knowledge Network (CDKN) and the National Renewable Energy Laboratory (NREL).
The All India Disaster Mitigation Institute (AIDMI) is a NGO registered in India. Located at Ahmedabad, Gujarat, India, it works on disaster risk reduction, climate change adaptation and disaster mitigation. It is a community-based ; action planning, action research and advocacy organization, working towards bridging the gap between policy, practice and research related to disaster mitigation. AIDMI have been working on six pillars: (i) Awareness generation, (ii) Capacity building, (iii) Policy advocacy, (iv) Direct implementation, (v) Research and publications, and (vi) Networking.
Global Infrastructure Basel Foundation (GIB) is an independent, not-for-profit foundation under Swiss law active in the field of sustainable urban infrastructure. The CEO of GIB is Louis Downing.
Nature-based solutions (NBS) is the sustainable management and use of natural features and processes to tackle socio-environmental issues. These issues include climate change, water security, water pollution, food security, human health, biodiversity loss, and disaster risk management. The European Commission's definition of NBS states that these solutions are "inspired and supported by nature, which are cost-effective, simultaneously provide environmental, social and economic benefits and help build resilience. Such solutions bring more, and more diverse, nature and natural features and processes into cities, landscapes, and seascapes, through locally adapted, resource-efficient and systemic interventions". In 2020, the EC definition was updated to further emphasise that "Nature-based solutions must benefit biodiversity and support the delivery of a range of ecosystem services." Through the use of NBS healthy, resilient, and diverse ecosystems can provide solutions for the benefit of both societies and overall biodiversity.
The Coalition for Disaster Resilient Infrastructure (CDRI) is an international coalition of countries, United Nations (UN) agencies, multilateral development banks, the private sector, and academic institutions, that aims to promote disaster-resilient infrastructure. Its objective is to promote research and knowledge sharing in the fields of infrastructure risk management, standards, financing, and recovery mechanisms. It was launched by the Indian Prime Minister Narendra Modi at the 2019 UN Climate Action Summit in September 2019.
The United Nations Development Programme (UNDP) in South Africa is one of the 177 offices of the UNDP’s global networks located in the country's capital, Pretoria. Its vision is to empower people's lives and help nations to become stronger and more resilient. As a part of the wider UNDP's development efforts, the local office is responsible for supporting the government to develop and implement policies to accelerate the attainment of the Sustainable Development Goals (SDG) in South Africa. UNDP interventions in South Africa focus on promoting actions that contribute to address the triple challenge of inequality, poverty and unemployment that the county faces. In that regard, the interventions include the promotion of youth employment; building resilience to climate change impacts; biodiversity conservation; water management; promotion of access to sustainable, clean and affordable energy; and promotion of citizens participation in democratic processes. Leaving no-one behind, gender mainstreaming and innovation are in the center of all UNDP cooperation.
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 and cities are deeply connected. Cities are one of the greatest contributors and likely best opportunities for addressing climate change. Cities are also one of the most vulnerable parts of the human society to the effects of climate change, and likely one of the most important solutions for reducing the environmental impact of humans. More than half of the world's population is in cities, consuming a large portion of food and goods produced outside of cities. The increase of urban population growth is one of the main factors in air-quality problems. In the year 2016, 31 mega-cities reported having at least 10 million in their population, 8 of which surpassed 20 million people. However, secondary cities - small to medium size cities are rapidly increasing in number and are some of the fastest growing urbanizing areas in the world further contributing to climate change impacts. The UN projects that 68% of the world population will live in urban areas by 2050. Hence, cities have a significant influence on construction and transportation—two of the key contributors to global warming emissions. Moreover, because of processes that create climate conflict and climate refugees, city areas are expected to grow during the next several decades, stressing infrastructure and concentrating more impoverished peoples in cities.
Climate change is the consequence of long-term alterations in the Earth's climate caused by the emission of greenhouse gases such as carbon dioxide (CO2) and methane (CH4). These gases can trap heat in the atmosphere, resulting in global warming and a heightened temperature on our planet. The activities carried out by humans, such as the utilization of fossil fuels, along with large-scale commercial agriculture and deforestation, are accountable for the release of these greenhouse gases. The escalating temperatures and escalating extreme heat conditions, uncertain and progressively unpredictable precipitation, and extreme weather provoke new challenges and exacerbate existing ones.
