Thursday, 25 February 2021 from 2:00-3:30pm, Manila Time
The first webinar of the Virtual Dialogues on Resilient Infrastructure for 2021 will be on “business unusual for resilient urban infrastructure”.
The interactive session will bring together experts and practitioners to discuss opportunities to accelerate new ways of advancing resilience of urban infrastructure and share new approaches and pilots on resilience in the urban space ready to be mainstreamed. Regional and global experts will share brief ‘burst’ talks followed by participant break-out groups to explore opportunities for ADB DMCs. Open to DMCs, ADB staff and consultants.
Real estate has led the way as an early adopter of TCFD requirements. In this whitepaper Willis Towers Watson outlines key lessons learnt throughout the sector.
Task Force on Climate-related Financial Disclosures (TCFD) is being increasingly adopted by the real estate sector, with the past two years seeing significant momentum in adherence to the guidance1. Indeed TCFD disclosures made by Real Estate Investment Trusts (REITs) and Real Estate Management and Development organisations have increased. Total disclosures made in 2020 more than doubled the total number reported for 2019, and the number of disclosures for 2020 exceeded the total combined disclosures made over the previous three years from 2017 to 20192. This is in spite of the macro-economic decline and uncertainty, which has hit some landlords especially hard.
Total TCFD disclosures made in 2020 were more than double than the total number reported from 2017 to 2019
With disclosure mandatory (on a ‘comply or explain’ basis) from 2022 for premium listed companies3, this whitepaper outlines the key themes and lessons learned from real estate experience in addressing TCFD guidance.
Following devastation from COVID-19 and monsoon rains, women collectives have been instrumental in securing crucial infrastructure provisions and service delivery.
India’s urbanisation challenges focus on large metropolitan cities and the proliferation of informal settlements within them. Relatively little is known about the impact of increasing informality of housing in less urbanised and smaller cities.
In 2019, SEWA Bharat, a national federation of organisations led by and for informal women workers, began supporting communities in Nehru Nagar and Mubarakpur, two low-income informal settlements in the city of Patna in Northeast India.
In light of COVID-19 and the annual monsoon rains that devastate the city, this blog highlights the efficacy of a women-led interface between communities and local governments in initiating basic service delivery and promoting participatory urban governance.
Where is the infrastructure?
Residents of Nehru Nagar and Mubarakpur tell similar stories. Faced with dangers of flooding, in the late 1900s they were moved from other areas in Patna and allocated land.
While Nehru Nagar is in the centre of the city, the map below shows the spatial segregation of the recently urbanised Mubarakpur, which lies outside the Patna Municipal Corporation and is administered by a smaller municipality.
Factors driving informality
Lack of data: the data gap stems from limited resources, capacities and government interest. At the macro level in particular, it prevents policy being formulated and implemented in a participatory manner.
Urban Local Bodies (ULBs) have limited information on demographics, ward boundaries and quality of service provision.
Inadequate service delivery: These settlements have seen little change despite at least five major urban development programmes in Patna. Service delivery is lacking despite the City Development Plan (2010-30) recognising Nehru Nagar as a notified slum, namely one that is legally recognised by the government.
The tables below highlight the inadequacies in basic infrastructural service, using waste collection and water supply across Nehru Nagar and Mubarakpur as examples.
Single collection point in settlement
No fixed point/collection system
This recognition can provide a degree of tenure security. Furthermore, many policies (including the Bihar State Slum Policy, 2011) advocate for delinking tenure from service provisioning, suggesting that the informal status of settlements may not be a hindrance. Without government data indicating where inadequacies are, can such schemes be implemented at all?
Piped water collection
Tubewells and handpumps
Shifting government responsibilities: Functions of elected ULBs are often transferred or shared with state, parastatal and private agencies. This reduces accountability and renders communication between departments and communities ineffective.
Key to SEWA’s mobilisation strategy is training women grassroots leaders (agevans) and developing women-led collectives.
Gradually, women identified common issues and collectively bargained for improved service delivery. Government officials and men in the community were surprised to see women huddle together to discuss and prioritise development issues for their neighbourhoods. The women reclaimed community spaces, gathering in temples, parks and community halls.
Agevans also collected data that addressed gaps in state capacity and ensured coverage of schemes like the Swacch Bharat Mission: India’s flagship programme focusing on toilet provisioning, and improved solid waste management.
The voluntary aspect of their work strengthens ties with communities and elected representatives. Their support widened the reach of the government’s COVID-19 relief measures, including awareness and ration delivery.
Such collective action emphasises the methods that empower communities and reinforce state accountability.
Community-led initiatives bring success
SEWA’s training familiarised residents with the appropriate government agencies for service provision and maintenance. Lacking a drainage system and well-paved roads, Mubarakpur floods heavily every year with 2019 being particularly devastating. Areas remained inaccessible for weeks.
Empowered with the right knowledge, residents approached the agency responsible for dealing with water logging of roads and homes.
Oral forms of grievance redressal are now supplemented with tools like community-endorsed letters and WhatsApp groups, enhancing accountability and follow-ups. Women leaders continued to request meetings and utilise newer means of communication– and their efforts paid off resulting in the construction of critical infrastructure, including a paved road and a drainage network.
This work helped nurture the relationship between community and government. Local leaders committed their funds to support further infrastructure projects.
In Mubarakpur, the collective work of the agevans led to a mobile toilet being installed to supplement overburdened community toilets and minimise open defecation. In Nehru Nagar, women reported inadequate water connections and poor water quality. They helped authorities identify leaking pipelines and monitor the repair work.
They also suggested locations for installing water tanks based on their local knowledge of accessible spaces in the dense settlement.
But well-intentioned schemes cannot be implemented unless local data is available – in Mubarakpur, SBM, had seen low take up. With the support of local women leaders and co-operation of the ward councillor, over 150 households applied for individual toilets.
Weak tenure security creates a fear of eviction. SEWA’s training emphasised on perceived tenure security. For some, this meant paying property tax to strengthen ownership claims. Others registered for electricity connections that serve as address proofs. Some ensured that social security documents were linked to current addresses.
Promoting citizen participation through localisation
SEWA’s work in small cities like Patna reveals deep problems with development trajectories and management mechanisms.
These cities need a dedicated approach to strengthening local governments using provisions available under India’s 74th Constitutional Amendment. This calls urgently for a framework that promotes citizen’s participation in building cities.
Women in Patna’s Nehru Nagar and Mubarakpur have shown how community-led action is paramount in identifying gaps in service delivery and in ensuring infrastructure provision. This community-led action is mirrored by greater willingness from local state actors.
Hence, in cities where the policy paradigm is weak, local politics and negotiations dominate. Such decentralised and localised modes of intervention create sustainable links between communities and governments and emerge as powerful tools in realising citizen’s rights and local political consciousness.
There is a wealth of options to consider when financing urban infrastructure. Some of these include but are not limited to: public-private partnership models; user fees or other domestically mobilized resources; loans from commercial or multilateral development banks; grants from facilities like the Green Climate Fund; or contributions from local businesses. Raising large investment volumes often requires a blend of these options. To build a financing model, cities need the capacity to identify and evaluate different sources of finance as well as present a convincing business case to financing partners. Especially for private investors, incentives do the trick––ranging from clear revenue streams to corporate social responsibility or insurance against the effects of extreme weather events.
One of the key challenges faced by cities is to develop a business case for projects that lack a clear revenue stream. This is usually the case with infrastructure projects addressing climate resilience, where the ideal financing blend may be hidden within the interests of complex stakeholder landscapes. The C40 Cities Finance Facility (CFF) has partnered with eThekwini Municipality (Durban) in South Africa to assist the city to overcome this challenge.
The CFF currently works with 17 cities in Asia, Africa, and Latin America, to prepare and finance infrastructure projects that build climate resilience, reduce emissions in public transport, or strengthen renewable energy generation. With a contribution by USAID, the CFF was able to strengthen its focus on climate resilience. In addition to projects in Dar es Salaam and Dakar, the CFF is working with the eThekwini Municipality in Durban, South Africa, on a water and waste management project.
Over the past decade, floods in eThekwini Municipality have increased in frequency and intensity, resulting in the loss of lives and damage to infrastructure. The flood risk in some of the city’s most vulnerable and disadvantaged communities is exacerbated by an increase in solid waste creation and the limited capacity for its collection and disposal. In response to this situation, the city piloted the ‘Sihlanzimvelo’ stream cleaning program in 2017. The initiative has reduced flooding—as well as crime and diseases—and removed waste and alien vegetation from 300 km of the city’s rivers and streams. Despite its success, the programme could not be scaled up due to a shortage of financial resources.
With CFF support, the city was able to engage local communities, businesses and NGOs to expand the pilot into a city-wide Transformative River Management Programme (TRMP). By aligning interests of local stakeholders, the program will create hundreds of community co-operatives to clean and maintain riverbeds. As per the current project scope, these cooperatives will employ up to 4,000 people. To finance the annual operational expenditure, the city has developed a cost recovery approach. By forecasting disaster relief and repair costs avoided through the TRMP, this system captures savings generated by investments in flood management programs. As such, the business case allows the city to establish an annual budget line to cover a large share of recurring operating costs. Contributions from residents and local business—in the form of river management fees—will complement these funds. Hard infrastructure elements, such as drainage systems, elevated bridges, and riverbank reinforcements, will be financed through debt and grants with the help of development banks and grant facilities. With this model, the 300 km pilot can be upscaled to 3,000 km of city rivers, with a potential for further extension up to 7,400 km in the medium term.
Aside from the technical preparation and financial modelling, the CFF has also worked with Durban to strengthen the municipality’s knowledge of topics such as transformative adaptation and financing resilience projects. Additionally, an intensive knowledge exchange has helped leading municipalities in the Central Kwa-Zulu-Natal Climate Change Compact, an effective exchange platform of municipalities across the South African province of Kwa-Zulu-Natal, to produce their own TRMPs. This will enable cities across the region to make the case for investments in ecological infrastructure to strengthen urban resilience.
Most of the building stock that will be needed over the next century in Africa is yet to be built. As the last continent to urbanize, Sub-Saharan Africa has a unique opportunity to learn from others and adopt resilient and sustainable practices from the onset.
Africa’s cities are already booming as thousands of rural households move to find better opportunities in the cities. Though the COVID-19 pandemic may have temporarily slowed this rural-to-urban migration, the trend appears to be inevitable.
The continent is not immune to natural hazards as the South gets hit by stronger and stronger cyclones, causing devastation and loss of life, homes and livelihoods. An estimated 240,000 houses were destroyed or damaged last year alone in Mozambique. North, South and east Africa also experience regular earthquakes.
A new motto has emerged claiming that there are no natural disasters, shifting the blame to poorly designed built environment and inadequate prevention systems which contribute death, destruction and economic losses.
Yet, Africa’s building sector seems to be repeating some of the mistakes of the past. Quality control remains a major issue across the continent where buildings are known to collapse even in the absence of natural hazards.
The COVID-19 pandemic has highlighted the need to urgently invest in disaster preparedness and mitigation. A disaster can quickly destroy decades of economic progress. While earthquakes are a quick disaster, a pandemic is a slow moving one. Our built environment must be designed to withstand these disasters and protect us.
Fortunately, resilience doesn’t need to be expensive and new technologies and innovations are constantly bringing down costs. As we are required to work remotely, we are developing new technologies to improve risk reduction during the pandemic and beyond. A few examples:
Machine learning to develop risk maps. Formal maps are rarely updated in Africa and often only cover major urban areas. Yet, local risk maps are fundamental to supporting proper urban development and reducing risks in the long term. Without risk maps, it is difficult to anticipate which properties may be vulnerable to flooding, landslides or even earthquakes and typhoons. Developing these maps should be a major priority to support planned urban development and make investments that will last. When on-the-ground data collection is time-consuming or made difficult with social distancing requirements, machine learning algorithms can be used to process satellite data and build local risk maps. This technology can help Africa overcome its major map gap and support municipalities across the continent develop urban plans that mitigate the risks of flooding, landslides and sea rise. Without access to detailed risk maps, buildings may be built in precarious ways which may lead to devastating life and property losses. Fortunately, machine learning is making this mapping process cheaper and faster.
Artificial Intelligence to assess the built environment. The World Bank’s Global Resilient Housing Group has developed technology to capture images from satellites and drones, which are processed through an algorithm to assess structural deficiencies. Without even setting foot on the ground, thousands of buildings can be assessed in a matter of minutes and enable policymakers to prioritize interventions. For example, buildings that present a high risk of collapsing during an earthquake or typhoon can be efficiently identified and thus retrofitted before the next disaster strikes.
Apps to undertake remote quality control. New apps, such as iBuild+ Miyamoto, have been developed to enable homeowners to quickly undertake a damage assessment of their home. Just like telehealth, they now have expert engineers at the tip of their fingertips- for a fraction of the cost! By uploading geotagged photos of their homes, households can access expert advice at a fraction of the costs. This app can also be used to monitor the quality of construction works and identify issues in real time before it is too late.
Programs to address and rate the resilience of new buildings: IFC, the private sector arm of the World Bank Group, is piloting a new program, the Building Resilience Index. The Index standardizes and quantifies disaster risk, gives guidance on risk management, and creates a reporting system on adaptation and resilience for the construction sector. The new tool will enable construction developers to identify ways of improving building resilience while minimizing costs. For investors and households, the Index will provide reassurance that the building can withstand significant hazards and protect both lives and properties.
Low-cost retrofit solutions. Retrofits are so rarely undertaken because they are deemed too expensive by both households and policymakers. Building new homes is easier to implement instead. But now, new construction technologies, such as Polypropylene (PP) bands or fiber-reinforced paint, are emerging that will not only make these retrofits cheaper but also much easier to implement. With little training, households can easily apply these retrofits themselves and bypass engineering and labor costs- which can often be crippling. Though easy to apply, these technologies are effective and enable households to greatly reduce the likelihood of structural collapse.
Construction will be a major driver of economic recovery worldwide, accounting for around 13% of the global GDP. These innovations can be part of a global effort to build (back) better. As cities in Africa continue to grow, climate change continues to accelerate and jobs are desperately needed, there has never been a better time to invest in resilience!
A fresh-off-the-press IDB technical guidance document will help LAC-based project developers prepare bankable Nature-based Solutions (NbS) projects that provide a substitute, compliment or safeguard to conventional ‘gray’ infrastructure projects.
Nature based Solutions (NbS) can play a central role in meeting the
rising demand for infrastructure, and strengthening the resilience of
infrastructure assets. They offer a cost-effective approach to enhance
resilience, while providing a range of social and environmental benefits (e.g.
recreational opportunities, habitat for biodiversity). In this context, NbS
refer to activities associated with the protection, management, enhancement,
and restoration of nature and implemented to deliver climate resilient
infrastructure. This could refer to re-forestation activities for erosion
control, coral reef restoration for coastal protection, and green space
creation for stormwater runoff control in densely populated urban areas.
There is a high awareness of the benefits and services that NbS can
provide, yet significantly less implementation within the Latin American and
Caribbean (LAC) context. Their potential remains largely untapped due to a
number of barriers that prevent mainstreaming NbS into project development.
Some of these barriers are upstream, for example, the lack of NbS incorporation
into infrastructure policy and planning documents, or a lack of financial
instruments to finance NbS. Other barriers are further downstream: these
include, the challenges of defining the business case and accessing finance and
funding, and the lack of adequate data, methods, and tools to incorporate NbS
into project development.
In tackling some of these downstream challenges, the IDB, in
collaboration with Acclimatise, have released a 12-step technical guidance
document to integrate NbS into project development. The Guidance is targeted to
planners, engineers, architects, contractors and operators interested in
preparing bankable climate resilient projects that incorporate NbS either as a
substitute, complement or safeguard to conventional infrastructure projects.
How was the guidance developed?
Figure 1: The twelve step process,
and two cross-cutting themes, for integrating NbS into project development
In September 2019, the IDB convened a workshop with a range of LAC-based
project developers and international experts with experience in NbS
implementation (e.g. Deltares, World Bank, World Resources Institute, U.S. Army
Corps of Engineers). As LAC as a whole is early stages of NbS implementation,
the IDB considered it opportune to leverage lessons learned from other parts of
the world where NbS is more mainstream in project development, for example the
Netherlands. At the workshop, the NbS experts iterated a preliminary technical
guidance document that was drafted based on a review of LAC and international
literature. The experts iterated the early stage draft and helped answer
important questions such as ‘is this how it works in practice?’ ‘what
steps or processes still need to be incorporated in this document?’, ‘what are
the important LAC-specific elements that must be included?’.
The NbS experts shared their experiences and insights which were
incorporated in the document, both at the workshop and throughout an extensive
review in the months after. The end
product is the result of a participatory process incorporating multiple
iterations with field experts, and should be considered a reference (or
“go-to”) document for project developers interested in developing NbS projects
in LAC, and globally.
The Technical Guidance Document is available in English and in Spanish and can be accessed here.
The Inter-American Development Bank’s (IDB) flagship publication “Development in the Americas” this year focuses on ways to improve the region’s infrastructure development to build resilience to climate change and its impacts. The report, “From Structures to Services: A New Vision for Infrastructure”, outlines a path to improve infrastructure services and manage fundamental challenges to achieve higher sustainability, affordability and quality in Latin America and the Caribbean (LAC).
Acclimatise co-authored chapter 8 of the report “Back to Nature: Alternatives to Concrete and Steel” which looks at the effectiveness of natural and combined natural-grey infrastructure compared to traditional approaches. The chapter explores six types of Natural Infrastructure (NI); coral reefs, mangroves, forests, constructed wetlands, green roofs and green spaces, across four geophysical settings; marine, coastal, terrestrial, and urban. The chapter discusses the efficacy of NI, cost-effectiveness, and also barriers and enablers to implementation.
The wider report covers tangible actions that can be taken to improve infrastructure services, and importantly the change in mindset that is required to implement novel solutions to complex challenges. It’s not just the ‘hardware’ that needs fixing (e.g. roads, power plants, water treatment plants) but also the software (e.g. regulations, governance) that needs updating.
The report argues that NI is one element of a new infrastructure paradigm that can help meet infrastructure requirements in a sustainable, affordable and high-quality manner. It involves managing natural (such as mangroves, forests) ecosystems and integrating natural and quasi-natural (e.g green roofs, bioswales) elements into the built environment, to deliver infrastructure services
As NI is new, it doesn’t have the long legacy in meeting infrastructure services in the same way that concrete and steel does, and the data, information and know-how that underpin it. Therefore, leveraging NI will require investments related to gathering and analyzing data to determine location-specific efficacy, planning, and securing financing. Yet the region can glean lessons learnt from other parts of the world where NI has become integrated into planning and development (e.g. the Netherlands) to leverage LAC’s endowment of natural capital to deliver infrastructure services.

Parks, green spaces and plant-covered hills are an effective defence against storm surges and tsunamis according to a Stanford University study. The research concludes that carefully engineered green infrastructure can offer similar levels of protection as large seawalls, while also benefiting for marine and coastal biodiversity, the aesthetic environment, and reducing costs.
The study, published on 4th May in the journal Proceedings of the National Academy of Sciences, quantified how tsunami waves of different heights interact with structures of various sizes and shapes at the coast. The research calls into question the wisdom of conventional approaches to coastal storm management, which are dominated by hard infrastructure development such as construction of large seawalls.
Seawalls have many disadvantages. They are expensive and inflexible, so they are hard to adapt if, for example, sea levels rise by more than expected. They can also damage marine ecosystems, and damage local economies in sectors such as fishing or tourism.
“If the wall collapses, the consequences are life shattering,” said senior study author Jenny Suckale, an assistant professor of geophysics in the School of Earth, Energy & Environmental Sciences. “Seawalls can not only create a false sense of security that can discourage swift evacuations. They can also end up breaking apart into blocks of rubble that tsunami waves then toss throughout a city.”
“It’s sort of intuitive that the moment you see it as a threat, you build a
wall,” Suckale said. But while it’s true that seawalls can address some tsunami
risks, the factors that make a place livable can be far more complicated. Most
coastal communities want to maximize their well-being, not minimize their risk
at the expense of everything else,” she said. “Do you really want to live
behind a huge concrete wall because there is a small chance that a big tsunami
will hit you? Let’s put more options on the table and have an informed debate.”
Green infrastructure must be carefully designed
When considering alternatives to sea walls, the study found
that green infrastructure solutions needed to be carefully designed and well
built in order to deliver the desired levels of protection. The study notes
that while coastal forests offer protection against storm surges, it takes
decades for trees to grow large enough to offer robust protection, and they are
not viable in some areas where protection is most needed – such as to protect
vulnerable towns and cities.
The study noted that as much attention needs to be paid to the design and
engineering of green infrastructure as to conventional infrastructure
development. According to the study, vegetation alone, has little effect on an
incoming wave’s energy. However, plants play an important role in fighting
erosion, thereby helping to maintain the shape, height and spacing of hills and
mounds, which do offer significant protection.
Suckale says that to date, green infrastructure has been designed more for
aesthetics than for performance. “Our study shows that design matters. There’s
a wrong and a right spacing; there’s a wrong and a right shape,”
“You should not use aesthetic criteria to design this. Right now, our
designs are not strategic enough,” she said. “This paper is a starting point
for understanding how to design these parks to derive maximum risk mitigation
benefits from them.”
To test the efficacy of hills and mounds in providing coastal defences, the
researchers modelled what happens when a tsunami wave hits a single row of
hills. They found that mounds reflect and dampen a tsunami wave’s energy about
as well as a seawall. Hills were also found to perform equally well in the case
of a very extreme event – a one-in-a-thousand-year tsunami. As a result, the
study concluded that there is little extra value in combining hills with
Along with improving the design green infrastructure, the study also
recommends that more space should be given between urban development and the
water’s edge. The researchers note that homes and infrastructure should be set
back with a broad buffer zone between them and multiple staggered rows of hills
that are larger toward the shore and smaller inland.

This “Toolkit for Climate Resilient Infrastructure PPP” and the accompanying report “Improving Climate Resilience in Public Private Partnerships in Jamaica” are the result of an 18-month project of the Climate Change Division at the IDB in collaboration with the Public-Private Partnership team at Development Bank of Jamaica and IMG Rebel.
The aim has always been to provide DBJ’s PPP professionals and, ultimately PPP professionals in the Caribbean Region, with pragmatic, practical solutions to integrate the assessment of climate risks and resiliency opportunities in the preparation of infrastructure projects through Public Private Partnerships (PPPs).
The need to consider climate change issues in the provision of infrastructure services through PPPs originates from two key observations in the context of Jamaica, but easily extendable to other climate vulnerable countries in Latin America and the Caribbean: On one side, these countries face many risks associated with climate change, with their infrastructure stock vulnerable to hazard events like hurricanes and landslides, as well as to chronic slow changes as sea level rise and perturbations in temperature and precipitations patterns. At the same time, Jamaica and many countries as such have been seeking to develop and build its infrastructure with an increased role for the private sector, developing Public Private Partnerships models that are constantly evolving in the region. As very long-dated contractual relationships, the success of PPPs is highly dependent on an accurate, sustainable and efficient distribution of risks and benefits between the public and private counterparts of the transaction – risk distribution that could be significantly perturbated by climate change, making the task of structuring efficient 20-30 years PPP contracts incredibly difficult if those risks are not identified, assessed and managed throughout the whole process of structuring a PPP transaction.
This project was borne then of an effort supported by IDB and the Government of Jamaica to understand how, if at all, Jamaica currently considers climate change within its PPP policies and project development processes and what steps the country can take to ensure that it does so. Considering the high potential for replication for such instruments, and the common challenges that several climate vulnerable countries face when developing their infrastructure projects, this companion Toolkit has been developed, including decision support tools for policy makers and developers partaking in the PPP development process and which applies to Jamaica as well as any country government seeking to ensure their PPPs are more resilient, was developed in conjunction with this effort. Report and Toolkit as well have been developed following the typical structure of the PPP process, from Project Identification, to the Business Case, the Transaction Structuring and the Management of the Contract during the whole life of the PPP project. In each phase, climate change risks may arise, as well as opportunities for an improved design for resilient and/or more productive infrastructure, and it would be important for such cases that risks and opportunities alike would be considered and followed-through in the different phases of the transaction to ensure, for example, that critical aspects identified in the project preparation phase are then included in the preparation of the tender documents and, as well, inform the performance indicators in the contract management phase.
The analysis for the report and toolkit has identified several instruments and tools already used to address climate change issues in the context of infrastructure production – albeit not always in a systematic way – that could be integrated in the PPP process in a more institutionalized and standardized manner, identifying options for a low-cost and seamless implementation in a Resilient PPP model. The Toolkit, finally, is to be considered a living document; we hope it could provide initial guidance to professionals implementing PPP projects in the region, while being open to improvements and updating as we collect evidence on other instruments that can be used to manage climate change risks and/ or create resiliency opportunities for the infrastructure of the Latin America and the Caribbean.

Kenyan President Uhuru Kenyatta fumed at construction delays on the Lamu Port-South Sudan-Ethiopia Transport Corridor in 2019 – a US$22 billion (£18 billion) transport network that includes a 32-berth port, highways, railways and pipelines. But these delays, caused by financing gaps, afforded fishers, pastoral farmers and conservationists time to challenge the project in court, and push for amended plans that better protect local habitats and migratory routes used by people, livestock and wildlife.
While major road and rail projects often break up wilderness and grazing lands, a sudden pause in construction can offer a lifeline to people fighting to protect these areas.
Lockdown restrictions and the uncertainty caused by COVID-19 have made sourcing labour and materials more difficult, increasing construction costs. The result is that infrastructure building has slowed globally, creating a unique opportunity to redesign road and rail projects around the world so that they benefit the people and environments they share the landscape with.
Barriers to travel
Dozens of new roads, railways and pipelines are under construction in sub-Saharan Africa due to a surge in investment in recent years. Although they are promised to bolster economic growth, our research shows that many of these new mega-highways and high-speed rail lines were approved without meaningful consultation between planners and local people. As a result, they tend to become new barriers that are difficult and dangerous to traverse, forcing people to travel long distances to reach safe crossing points.
In dry regions, this can make it difficult to reach vital water sources. Amid farmland and forests, construction can push people from their land or force them to travel further to reach it. Deforestation usually comes before construction too, which encourages people to migrate further into woodland, building new settlements that drive more forest clearing.
Poorly designed roads and rail lines can take a heavy toll on human and animal life. During our research between 2017 and 2019, we found too few safe crossing points, inadequate signage and lax speed enforcement along new highways and railways in Kenya and Tanzania, resulting in numerous road accidents.
Conservationists are particularly worried by growing roadkill sightings along a new highway in northern Kenya. Endemic and endangered species like the Grevy’s zebra are often killed in collisions with cars and lorries after wandering onto roads that now criss-cross their range. As one pastoral farmer living alongside the new highway exclaimed
How many animals have died? Uncountable.
Fortunately, there are lots of proven strategies for preventing transport projects from fragmenting habitats, such as building passages across new highways and railways that migratory species can use. Repairing environmental damage caused by construction, by filling in quarries that produce construction materials, for example, can also help restore grazing land for livestock and wildlife.
The Mongu-Kalabo road constructed over the Barotse floodplain in western Zambia shows these ideas in action. Completed in 2016, the road was built with 26 bridges over the floodplains and regular culverts between bridges, allowing water and wildlife to move across the floodplain without impeding road traffic and trade, even during seasonal floods.
The road was also planned with local cultures in mind. Wetland livelihoods, such as fishing and floodplain farming, aren’t affected by the road since the regular movement of fish and water remains largely undisturbed. By maintaining these flows across the floodplain, cultural traditions have been protected. The annual Kuomboka ceremony that takes place at the end of the rainy season can continue, when the Litunda (king of the Lozi people) moves from his compound in the Barotse floodplain to higher ground.
There is no single blueprint for building roads and railways that allow humans and nature to thrive. Wherever construction is planned, public participation is vital. Gathering the knowledge local people have of their environment can improve the design of these projects, but this insight cannot come from rushed consultations or impact assessments conducted from a distance. Only meaningful and ongoing engagement with local communities and environmental authorities will do.
Major infrastructure investment will likely be key to pulling the global economy out of recession. The opportunity to mould upcoming projects won’t last forever, so let’s ensure any new road and rail project is designed with respect to the rights of people and nature.
