It is not all doom and gloom...


Where are we coming from?


I know most, if not all, of the past blog posts have painted a gloomy picture of state of the environment and human well-being but to understand where we are headed, it is always advisable that we look at where we have come from. As mentioned in the previous post, which summarized key losses and damages around the globe, this last blog post will endeavour to highlight "some of the interventions and responses that are being implemented/or should be implementation to enhance adaptation to climate-related disasters, build resilience, and promote environmental sustainability"

Anything to note?


On Wednesday this week, an article on the guardian documented how 50 billion US$ had been spent by insurers on natural-disaster related claims in 2016. Although the source and accuracy of the figure is not clear, it intimates that there were 'exceptional' flood events in 2016 that accounted for approximately 34% of all the losses up from last decade's avaerage of 21%. Most of this flood events (and storms), according to the article, were particularly common in Europe and accounted for 6 billion US$. Worse still, the December 2016 flooding in the United Kingdom was marked as the beginning of major annual floods. Earlier on, another article on the guardian detailed how indigenous people of Alaska are facing eminent threat to culture-erosion (language and hunting) as a result of the arctic ice loss. From these scenarios, we deduce that loss and damage goes beyond monetary costings to non-economic - as elaborated in my very first blog post.

The IPCC AR5 affirms that there has been increased global surface temperatures - 0.85°C  on average relative to pre-industrial records. In assessing "What the gap in emissions means for human and ecological systems", I highlighted the likely implications of such a trajectory, which, among other things will increase the risks of, and costs associated with climate disasters thereby straining vulnerable populations across the world. 

How can loss and damage to climate-related disasters be avoided?


It is worth noting that although it is critical to mitigate against any climate-related disasters in order to reduce loss and damage, there is high certainty that the climate change impacts will continue to take an upward linear trend in future. It is therefore imperative that different parties – decision/policy makers, stakeholders and different vulnerable group –  work on various adaptation and disaster risk reduction strategies in order to deal with unavoidable losses and damages.  Options such as risk transfer; risk retention; migration; recovery, rehabilitation and reconstruction, are crucial in reducing loss and damage from natural hazards. A number of strategies are further discussed;

Adaptation


Adaptation can be hazard-specific. For instance, in the case of drought adaptation strategies could include planting drought-resistant crops, harvesting water, managing soil fertility, diversifying livelihoods and voluntary migration based on the seasons. Measures for extreme temperatures include improving design of buildings and cities. Flood adaptation strategies generally involve building dams and diversions and moving settlements from coastlines and flood prone areas. 

Ecosystem-based Adaptation (EBA)


The idea behind EBA is that the various components within the ecosystem can be used to enhance adaptation thereby reducing risk and enhancing resilience to climate shocks.  In EBA, it is assumed that the ecosystems will be diverse and well managed in order for them to contribute towards climate change adaptation(Reid et al., 2009). For instance, Reid, 2016Jones et al., 2012 have documented the role of ecosystems; wetlands act as reservoirs especially for flood water,  mangroves and coral reefs have proven to be strongholds against storm surges, and well vegetated hills reduce landslides and erosion.

Community-based adaptation (CBA) 


With this approach, climate change interventions start at the community level and focus on immediate needs of vulnerable communities and how to address climate variability and change (Ensor and Berger, 2010). CBA looks at the potential of both local and scientific knowledge in addressing the vulnerabilities to disasters and any other development challenges hence the interventions are thought of as being community-centric.

Integrated Early warning systems  (EWS)


EWS have the potential to reduce the risks associated with extreme climate events, hence reduced loss and damage. The design of EWS needs to be wholesome – integrated, actionable and timely – in order to evoke early action.  A study conducted by UNEP in 2013 reinforces the need to ensure the needs of all vulnerable communities, irrespective of their socio-economic statuses -  are incorporated in the design of EWS.

Conclusion


To safeguard the environment and ensure human well-being, there is need to work towards reducing losses and damages. As the effects of climate change persist, ecosystems and the services they offer are put at risk. A better understanding of such impacts is needed by decision makers in order to design and implement risk management frameworks that are comprehensive and reliable. In quoting one of my statements when I unpacked loss and damage;
"Dealing with loss and damage substantially depends on enabling polices at all levels - sub-regional, regional and global. Among the major policy instruments that contribute towards addressing loss and damage are the Sendai Framework on Disaster Risk Reduction, the Paris Agreement, Sustainable Development Goals and the New Urban Agenda set to be agreed upon in Quito, Ecuador during the Habitat III Conference. We can all agree that in the end, its the actions taken by countries that will determine whether the human and ecological systems will withstand the loss and damage force" 

Its Bye for now....

Thank you for following me across the continents, in countries and cities/villages, as I painted the picture of natural disasters and their implications on the people and the planet. Lets meet again in future :)

Can the New Urban Agenda reduce loss and damage in cities?


Good news?


So finally the New Urban Agenda has been adopted by countries adding onto the list of international agreements that have been reached within the last nearly 12 months! The recently celebrated first anniversary since the 2030 Agenda for sustainable development (SDGs) was adopted, the Paris Agreement on climate change that continues to be ratified by parties, and the Sendai Framework Framework for Disaster Risk Reduction (DRR) 2015-2030. The New Urban Agenda outlines provisions that would ensure, among other things, integrated urban planning that includes climate change aspects.

Urban population at a glance…

"By 2050 the world urban population is expected to nearly double, making urbanization one of the 21st century’s most transformative trends."  
The distribution of the  regions' population from 1950–2010, with 2030 and 2050 projections are summarized below;

 Source: EM-DAT: The OFDA / CRED International Disaster Database as compiled in IFRC, 2010 

A few more facts from the UNHABITAT report

  • Urban population likely to double by 2050
  • Roughly 7 out of every 10 urban dwellers are found in developing world accounting for 82% of the world population
  • Cities in Africa among the fastest growing in the world
  • Latin America is the most urbanized with 80% of population living in urban areas. This is expected to be 87% by 2050.
  • European population increasing at an average of 0.67%
  • Africa and Asia are ranked least urbanized despite the high urban population in urban areas.


How are cities vulnerable to loss and damage due to climate change?


The greenhouse gas emissions are highest in cities due to exponential growth in industrialization (hence intensive use of energy), human population and related activities.  If we treat cities as closed systems with inlets but no outlets, you can picture a situation where the system itself is overstretched to its limits. The unprecedented increase in urban population and the subsequent overutilization of resources, especially in least developing countries, by no means places enormous pressure on urban resources and the capacity of existing systems to cope or respond to any uncertainties.

UNHABITAT and International Federation of the Red Cross reports agree that cities, especially those that are unplanned, continue to be susceptible to natural disasters like flooding, extreme increase in temperature, drought and earthquakes. The table below summarizes the major losses and damages faced in some of cities around the world due to natural disasters.

Can the New Urban Agenda address loss and damage in cities?


Despite the fact that the New Urban Agenda is non-binding and lacks clear strategy of tracking the progress, a number of provisions address key climate change and DRR concerns. For instance, the agenda envisages
"cities and human settlements that;…adopt and implement disaster risk reduction and management, reduce vulnerability, build resilience and responsiveness to natural and man-made hazards, and foster mitigation and adaptation to climate change … protect, conserve, restore, and promote their ecosystems, water, natural habitats, and biodiversity, minimize their environmental impact, and change to sustainable consumption and production patterns."
Perhaps some of the great environmental scores of this agenda is that it acknowledges threats posed by climate change and its related risk, and recognizes that vulnerabilities vary depending on various demographic characteristics. The agenda commits to promoting resilience within cities and reducing GHG emissions in line with Sendai Framework and the Paris Agreement respectively, and further to support “adaptation plans, policies, programmes, and actions that build resilience of urban inhabitants”

For cities to thrive, the provisions in the agenda  need to be implemented by countries. The Sendai framework emphasizes that;
“More dedicated action needs to be focused on tackling underlying disaster risk drivers, such as the consequences of poverty and inequality, climate change and variability, unplanned and rapid urbanization, poor land management and compounding factors such as demographic change, weak institutional arrangements, non-risk-informed policies, lack of regulation and incentives for private DRR investment, complex supply chains, limited availability of technology, unsustainable uses of natural resources, declining ecosystems, pandemics and epidemics.”
However, the resilience of cities also go a step further. Childers et al, 2014 argue that there is need for transformative integration where urban design meets the ecological realities of the time. The authors believe that such a model will enhance resilience of urban dwellers in the face of climatic hazards and future uncertainties. Taking the case of Indian cities, for instance, the animation below summarizes the how cities can build resilience.
