Forget Public-Private Partnerships. Share data and transport innovation will follow

“To help close the gap between public transit and your doorstep, we’re teaming up with Amtrak,” announced Lyft, Uber’s largest competitor, earlier this month. The partnership will allow Americans to ditch their cars and let the sharing economy deliver them seamlessly to and from the train station. Compelling, right?

For urban policymakers, maybe not.

Public-private partnerships (we can debate whether Amtrak is public or private later, rail nerds) seek to solve the first/last mile problem, and they do it very well. Multi-modal transport helps users overcome the friction of reaching a public transport hub, tempting many out of their cars.

The Pinellas Suncoast Transit Authority (PSTA) in Florida was amongst the first to launch such a scheme, named DirectConnect. The Authority pays up to $5 towards journeys made with Uber, a local taxi service, or a wheelchair-accessible taxi firm within designated zones, encompassing poorly served residential areas and starting or finishing at DirectConnect stops, mostly at the ends of bus lines. The scheme increases passenger numbers on primary bus services at a fraction of the cost of maintaining poorly performing branch lines, freeing up public resources to be deployed more efficiently elsewhere.

Schemes like this mean fewer cars and so less air pollution, more road space, lower demand for parking space, and lower atmospheric carbon emissions. What’s not to like?

Well for one thing, there’s little to suggest that this sort of multi-modal travel requires formal partnership: 25 per cent of Lyft’s journeys in Chicago are to a public transport node. Likewise, 40 per cent of Uber’s journeys in London start or end within 200 metres of an underground stop.

Data released by the firm last year after the opening of London’s Night Tube illustrated the dominance of these multi-modal journeys even more clearly. The number of journeys to or from an underground station during Night Tube hours has risen by 22 per cent since the service began. What’s more, pick-ups in Central London have fallen, while pick-ups at stations beyond the centre have risen by up to 300 per cent and 63 per cent on average. Clearly, consumers are well ahead of Lyft and Amtrak.

All this suggests that formal public-private partnerships may be unnecessary: if consumers can organise their own multi-modal transit, what need is there for expensive service integrations?

And by providing high quality real time transit data, metropolitan governments have reduced the need to partner with private companies to improve urban transportation. Applications such as CityMapper in the United Kingdom and Transit in the United States depend on free public-sector data showing, for example, when the next bus is due. Given access to open data, companies like these can give people the information they need to link multiple modes of transit.

Coupling its own data on urban transit with that made available by the private sector, CityMapper has gone so far as to provide its own ‘public’ transport service, or ‘social hyper-local multi-passenger pooled vehicle’, as the company calls it. The Night Rider, a 9pm to 5am bus route running through the heart of East London, from Aldgate to Highbury and Islington underground stations via Shoreditch and Dalston, will service an area neglected by public transport at night, a boost to the local economy along the way.

So what need is there for the public sector to partner with private companies, in an age of open metropolitan data? Principally, to ensure that no one is left behind.

Services like Uber require users to own a smartphone and have the ability to operate it, to have a bank account and to be comfortable making payments via an app, to be able bodied (very few ridesharing vehicles are accessible, leading to court cases across the pond), and, of course, to have the money to pay for what is ultimately a taxi, however cheap. Schemes such as DirectConnect allow the public sector to ensure that multimodal transport is accessible to the poor, the disabled, and those uncomfortable with smartphones by uniting public transport with accessible private vehicles that can be ordered by telephone and paid for with cash.

Partnerships like that between Uber and Transit, within the private sector but underpinned by open source public sector data, help us to navigate the multimodal city more efficiently than ever before. Public-private partnerships, on the other hand, are useful only in that they guarantee service accessibility – an aim that could perhaps be achieved by other means.

The IPPC report on the melting ice caps makes for terrifying reading

Earlier this year, the Intergovernmental Panel on Climate Change (IPCC) – the UN body responsible for communicating the science of climate breakdown – released its long-awaited Special Report on the Ocean and Cryosphere in a Changing Climate.

Based on almost 7,000 peer-reviewed research articles, the report is a cutting-edge crash course in how human-caused climate breakdown is changing our ice and oceans and what it means for humanity and the living planet. In a nutshell, the news isn’t good.

Cryosphere in decline

Most of us rarely come into contact with the cryosphere, but it is a critical part of our climate system. The term refers to the frozen parts of our planet – the great ice sheets of Greenland and Antarctica, the icebergs that break off and drift in the oceans, the glaciers on our high mountain ranges, our winter snow, the ice on lakes and the polar oceans, and the frozen ground in much of the Arctic landscape called permafrost.

The cryosphere is shrinking. Snow cover is reducing, glaciers and ice sheets are melting and permafrost is thawing. We’ve known this for most of my 25-year career, but the report highlights that melting is accelerating, with potentially disastrous consequences for humanity and marine and high mountain ecosystems.

At the moment, we’re on track to lose more than half of all the permafrost by the end of the century. Thousands of roads and buildings sit on this frozen soil – and their foundations are slowly transitioning to mud. Permafrost also stores almost twice the amount of carbon as is present in the atmosphere. While increased plant growth may be able to offset some of the release of carbon from newly thawed soils, much will be released to the atmosphere, significantly accelerating the pace of global heating.

Sea ice is declining rapidly, and an ice-free Arctic ocean will become a regular summer occurrence as things stand. Indigenous peoples who live in the Arctic are already having to change how they hunt and travel, and some coastal communities are already planning for relocation. Populations of seals, walruses, polar bears, whales and other mammals and sea birds who depend on the ice may crash if sea ice is regularly absent. And as water in its bright-white solid form is much more effective at reflecting heat from the sun, its rapid loss is also accelerating global heating.

Glaciers are also melting. If emissions continue on their current trajectory, smaller glaciers will shrink by more than 80 per cent by the end of the century. This retreat will place increasing strain on the hundreds of millions of people globally who rely on glaciers for water, agriculture, and power. Dangerous landslides, avalanches, rockfalls and floods will become increasingly normal in mountain areas.


Rising oceans, rising problems

All this melting ice means that sea levels are rising. While seas rose globally by around 15cm during the 20th century, they’re now rising more than twice as fast –- and this rate is accelerating.

Thanks to research from myself and others, we now better understand how Antarctica and Greenland’s ice sheets interact with the oceans. As a result, the latest report has upgraded its long-term estimates for how much sea level is expected to rise. Uncertainties still remain, but we’re headed for a rise of between 60 and 110cm by 2100.

Of course, sea level isn’t static. Intense rainfall and cyclones – themselves exacerbated by climate breakdown – can cause water to surge metres above the normal level. The IPCC’s report is very clear: these extreme storm surges we used to expect once per century will now be expected every year by mid-century. In addition to rapidly curbing emissions, we must invest millions to protect at-risk coastal and low-lying areas from flooding and loss of life.

Ocean ecosystems

Up to now, the ocean has taken up more than 90 per cent of the excess heat in the global climate system. Warming to date has already reduced the mixing between water layers and, as a consequence, has reduced the supply of oxygen and nutrients for marine life. By 2100 the ocean will take up five to seven times more heat than it has done in the past 50 years if we don’t change our emissions trajectory. Marine heatwaves are also projected to be more intense, last longer and occur 50 times more often. To top it off, the ocean is becoming more acidic as it continues to absorb a proportion of the carbon dioxide we emit.

Collectively, these pressures place marine life across the globe under unprecedented threat. Some species may move to new waters, but others less able to adapt will decline or even die out. This could cause major problems for communities that depend on local seafood. As it stands, coral reefs – beautiful ecosystems that support thousands of species – will be nearly totally wiped out by the end of the century.

Between the lines

While the document makes some striking statements, it is actually relatively conservative with its conclusions – perhaps because it had to be approved by the 195 nations that ratify the IPCC’s reports. Right now, I would expect that sea level rise and ice melt will occur faster than the report predicts. Ten years ago, I might have said the opposite. But the latest science is painting an increasingly grave picture for the future of our oceans and cryosphere – particularly if we carry on with “business as usual”.

The difference between 1.5°C and 2°C of heating is especially important for the icy poles, which warm much faster than the global average. At 1.5°C of warming, the probability of an ice-free September in the Arctic ocean is one in 100. But at 2°C, we’d expect to see this happening about one-third of the time. Rising sea levels, ocean warming and acidification, melting glaciers, and permafrost also will also happen faster – and with it, the risks to humanity and the living planet increase. It’s up to us and the leaders we choose to stem the rising tide of climate and ecological breakdown.
