βWe have a lot of capability here,β says Stoner, director of the Tata Center for Technology and Design at MIT, and deputy director for Science and Technology at the MIT Energy Initiative (MITEI). βThere are world-class people in the areas of disaster relief, electrification, regulation, water systems, transportation, and finance. We needed to show the people in those islands that MIT cared.β
Stoner reached out to his colleague Donald Lessard of the MIT Sloan School of Management. Together with various student groups, they reached out to other colleagues, who in turn reached out to more. In a short few weeks they organized a major conference, which took place over two days in early December. Faculty from across MIT met with representatives from many of the affected Caribbean islands, assessing the damage to those nationsβ electrical grids, housing, water systems, and roads, and drafting strategies to both rebuild them and make them more resilient.
During the event, Keith Mitchell, prime minister of Grenada, noted that global warming had created βan existential threatβ to Caribbean nations facing dramatic rises in sea levels and hurricanes of increasing ferocity. Ricardo RossellΓ³ β01, governor of Puerto Rico, reported that close to half a million homes had been destroyed or severely damaged, and that the islandβs power grid and water systems had been severely compromisedβand all that in the context of a dramatic debt crisis that had crippled Puerto Ricoβs capacity to borrow. βThe hurricane happened on an island that was already battered by a hurricane of the man-made kind,β said RossellΓ³, who graduated MIT with a degree in chemical engineering.
The December conference, while significant, was only the first step in MITβs ongoing effort to bring its expertise to relief and reconstruction efforts in the Caribbean and perhaps more importantly, to develop a template that can guide the Instituteβs response to future disasters. βWe held sessions on housing, electricity, water systems, and finance,β says John FernΓ‘ndez β85, professor of building technology in the Department of Architecture, and director of MITβs Environmental Solutions Initiative. βBut the concept that dominated our conference was the ongoing tension between the need for an immediate response, and the desire to build long-term resilience. There are lives to be saved. Houses and infrastructures need to be rebuilt. Still, we all agreed it was time to stop doing business as usual. Simple reconstruction merely restores the systems that have already failed.β
The short term and the long term
A first measure, FernΓ‘ndez suggests, is building dwellings and infrastructure that can withstand the Caribbean environmentβa region that due to climate change will be hit with increasingly ferocious storms whipping up winds of 150 or even 200 mph. βWe already tend to build for high winds in places like Florida,β says FernΓ‘ndez. βBut apart from Bermuda, where theyβve built in concrete and stone forever, itβs just not done in the Caribbean, due mostly to socioeconomic conditions there.β
The tension between immediate response and long-term resilience is not limited to the Caribbean or to developing nations. Consider Houston, Texas, which suffered disastrous flooding during Hurricane Harvey this past August. FernΓ‘ndez recognizes the value MIT student and faculty groups can provide in Puerto Rico, Grenada, and their neighbors, offering labor and supplies, expertise, and bringing best practices to those islandsβbut he thinks the Instituteβs work in the Caribbean will pay dividends in seas and lands all over the earth. βI believe at least half of the value of our involvement in the Caribbean will be about transferring what we learn there elsewhere,β says FernΓ‘ndez. βOur work will impact people who live on these islands. But the general principles will apply to every city and human settlement. We now understand the problem of the short term and the long term. We know the steps to take to bring these islands up to best practices. There was a lot of excitement at the conference that we could actually solve this.β
Part of the solution, for conference attendees and for future relief and reconstruction projects, will involve developing a new definition for resilience. Lawrence Vale SM β88, who helped moderate a panel on human settlements at the December conference, argues that it is not sufficient to reinforce buildings and systems to withstand powerful natural disasters, or to rebuild housesβno matter how strong and sturdyβon the first piece of available land. βIf we really want to talk about resilient housing and cities, we first have to ask whether this new housing is safe from future risk,β he explains. βWill it be an asset for the people who are destined to live there?β
For Vale, Ford Professor of Urban Design and Planning who also directs MITβs Resilient Cities Housing Initiative, well-built housing on environmentally sound land is only one element in the creation of resilient housing. βWhen we rebuild after a disaster, we need to ask ourselves what we are doing to help people connect to their neighbors, their communities, and their full lives,β says Vale. βAfter a disaster, the tendency is just to build quickly, and this often disrupts the networks that people depend on to lead viable lives. Itβs a case of getting the house right and the job wrong.β
Vale cites the examples of post-tsunami Indonesia, and that of northern Colombia, where violent landslides displaced thousands of neighborhood residents. βIn both cases, the people who came to rebuild saw the survivors as victims, as desperate people they were rescuing with this new housing.
What they didnβt see was that these so-called victims often owned their own land, that they grew food, that they had jobs and families nearbyβ that they were able to live a complete life, despite low incomes. After reconstruction, they may have had houses that looked better in photographs. But the houses were nowhere near their jobs or affordable transportation.β
Financing the future
Building resilience requires not only willpower and knowledge. Relief supplies need to be purchased and delivered. New houses need to be paid for, and costly power grids or water systems somehow financed. βSpending extra funds to build resilient infrastructure is almost always a good idea,β says Donald Lessard, the Epoch Foundation Professor of International Management at the MIT Sloan School of Management. βBut itβs hard to capture the future value and raise money for the additional investment in the present.β
Lessard, who moderated a panel on funding sources for resilient reconstruction at the December conference, says a first step would be for these countries to insure their infrastructures. βWe now understand that the Caribbean is going to have a 100-year storm, say, every five years,β he says. βEven a small country can purchase insurance. This will require an up-front payment, but perhaps it can embed the cost of that insurance in the money the country receives from donors or lenders. And then it can invest in ways to make that infrastructure truly sustainableβ raising equipment 20 feet off the ground, or building highways with better runoff. The next time a catastrophe hits, the insurance proceeds will offset income losses and they can rebuild again. If insurance underwriters were on their game, theyβd realize the value of these investments and reduce the premiums. Weβre not living in that ideal world yet, but many Caribbean islands already participate in a regional catastrophe risk pool, and we also have instruments like green bonds and catastrophe bonds that serve this purpose.β
Lessard and his colleagues recognize that finance is only part of the solution to providing relief and creating resilience in the Caribbean and in other regions threatened by climate change. They also realize that while many disasters may share similar elements and consequences, each one of them is ultimately unique. βWe recognize that all disasters are local and there is no one-size-fits-all solution,β says Miho Mazereeuw, a professor of architecture and urbanism who directs MITβs Urban Risk Lab. βThis certainly holds true for Puerto Rico.β
The US island commonwealth is currently saddled with $70 billion in bond debt. Forty-five percent of its residents are living under the poverty line and 12.5% of them are unemployed. Yet because Puerto Rico is neither a country nor a state, it cannot devalue its currency or declare bankruptcy. βFrom the top, Puerto Rico has financial troubles that create challenges for its government,β explains Mazereeuw. βDespite widespread poverty, there is a tremendous amount of energy in the islandβs community-based efforts, and yet the unregulated housing and diverse terrain make recovery extremely complex. Even within the island there are discrepancies. Things are more or less returning to normal in San Juan, the capital. But many of the smaller, remote towns are still struggling.β To help to address the difficulties these communities are facing, the MIT Urban Risk Lab is working to develop alternative models for post-disaster housing in Puerto Rico and other contexts.
MITβs December conference kicked off a series of initiatives for the Institute to help bring its expertise to the Caribbean. Several teams have traveled to the region to build roofs, to advise on recovery and reconstruction, and to interview residents and relief workers. Faculty members have held follow-up meetings, consulted with regional officials and agencies, and have briefed MIT President L. Rafael Reif on their progress. Itβs not the first time MIT has stepped up to provide relief. But there is something different in this effort.
βEvery time a natural disaster occurs, MIT moves to help,β says Mazereeuw. βBut whether itβs Nepal or Mexico or Colombia, itβs been an ad hoc process. This is the first time weβve made a point to come together before weβve drafted our individual courses of action. I think this conference has set a good precedent for how we respond in the future.β
