Urban nature has a critical role to play in the future liveability of cities. An emerging body of research reveals that bringing nature back into our cities can deliver a truly impressive array of benefits, ranging from health and well-being to climate change adaptation and mitigation. Aside from benefits for people, cities are often hotspots for threatened species and are justifiable locations for serious investment in nature conservation for its own sake.

Australian cities are home to, on average, three times as many threatened species per unit area as rural environments. Yet this also means urbanisation remains one of the most destructive processes for biodiversity.

Despite government commitments to green urban areas, vegetation cover in cities continues to decline. A recent report found that greening efforts of most of our metropolitan local governments are actually going backwards.

Current urban planning approaches typically consider biodiversity a constraint – a “problem” to be dealt with. At best, biodiversity in urban areas is “offset”, often far from the site of impact.

This is a poor solution because it fails to provide nature in the places where people can benefit most from interacting with it. It also delivers questionable ecological outcomes.

Building nature into the urban fabric

A new approach to urban design is needed. This would treat biodiversity as an opportunity and a valued resource to be preserved and maximised at all stages of planning and design.

In contrast to traditional approaches to conserving urban biodiversity, biodiversity-sensitive urban design (BSUD) aims to create urban environments that make a positive onsite contribution to biodiversity. This involves careful planning and innovative design and architecture. BSUD seeks to build nature into the urban fabric by linking urban planning and design to the basic needs and survival of native plants and animals.

BSUD draws on ecological theory and understanding to apply five simple principles to urban design:
  1. protect and create habitat
  2. help species disperse
  3. minimise anthropogenic threats
  4. promote ecological processes
  5. encourage positive human-nature interactions.
These principles are designed to address the biggest impacts of urbanisation on biodiversity. They can be applied at any scale, from individual houses (see Figure 2) to precinct-scale developments.

BSUD progresses in a series of steps (see Figure 1), that urban planners and developers can use to achieve a net positive outcome for biodiversity from any development.

BSUD encourages biodiversity goals to be set early in the planning process, alongside social and economic targets, before stepping users through a transparent process for achieving those goals. By explicitly stating biodiversity goals (eg. enhancing the survival of species X) and how they will be measured (eg. probability of persistence), BSUD enables decision makers to make transparent decisions about alternative, testable urban designs, justified by sound science.

For example, in a hypothetical development example in western Melbourne, we were able to demonstrate that cat containment regulations were irreplaceable when designing an urban environment that would ensure the persistence of the nationally threatened striped legless lizard (Figure 3).

What does a BSUD city look, feel and sound like?

Biodiversity sensitive urban design represents a fundamentally different approach to conserving urban biodiversity. This is because it seeks to incorporate biodiversity into the built form, rather than restricting it to fragmented remnant habitats. In this way, it can deliver biodiversity benefits in environments not traditionally considered to be of ecological value.

It will also deliver significant co-benefits for cities and their residents. Two-thirds of Australians now live in our capital cities. BSUD can add value to the remarkable range of benefits urban greening provides and help to deliver greener, cleaner and cooler cities, in which residents live longer and are less stressed and more productive.

BSUD promotes human-nature interactions and nature stewardship among city residents. It does this through human-scale urban design such as mid-rise, courtyard-focused buildings and wide boulevard streetscapes. When compared to high-rise apartments or urban sprawl, this scale of development has been shown to deliver better liveability outcomes such as active, walkable streetscapes.

By recognising and enhancing Australia’s unique biodiversity and enriching residents’ experiences with nature, we think BSUD will be important for creating a sense of place and care for Australia’s cities. BSUD can also connect urban residents with Indigenous history and culture by engaging Indigenous Australians in the planning, design, implementation and governance of urban renaturing.

What needs to change to achieve this vision?

While the motivations for embracing this approach are compelling, the pathways to achieving this vision are not always straightforward.

Without careful protection of remaining natural assets, from remnant patches of vegetation to single trees, vegetation in cities can easily suffer “death by 1,000 cuts”. Planning reform is required to move away from offsetting and remove obstacles to innovation in onsite biodiversity protection and enhancement.

In addition, real or perceived conflicts between biodiversity and other socio-ecological concerns, such as bushfire and safety, must be carefully managed. Industry-based schemes such as the Green Building Council of Australia’s Green Star system could add incentive for developers through BSUD certification.

Importantly, while BSUD is generating much interest, working examples are urgently required to build an evidence base for the benefits of this new approach.The Conversation

How Shareholder Profits Conquered Capitalism: And How Workers Can Win Back its Benefits for Themselves

In the early days of industrial capitalism there were no protections for workers, and industrialists took their profits with little heed to anyone else. 

Following the growth of the labour movement, the establishment of trade unions and the founding of the welfare state in the first half of the 20th century, corporations in decades after World War II embraced a more open, stakeholder capitalism, where profits were shared between employees, managers and shareholders. This led to a flourishing middle class as workers and communities benefited from the success of the corporations of which they were part.

But since the 1970s the pendulum has swung back towards a system where profits are shared less widely, causing major upheavals in society and the fortunes of labour and the middle classes.

In the US, labour’s share of income had been close to 70% until the 1970s, but had shrunk by the beginning of the 1980s even as profits increased. In the 21st century this accelerated: in 2000, labour’s share of income in the US accounted for some 66%, whereas corporate profits accounted for a little over 8%. 

Today, labour’s share has fallen to 62% while profits have risen to 12%. The same trend is repeated in the UK, where labour’s share of income has reduced from almost 70% in the 1970s to around 55% percent today.

Where has the money gone? For decades, real incomes for workers have largely stagnated while those of top executives have skyrocketed. In 2017, the top executives of America’s largest companies enjoyed an average pay increase of 17.6%, while workers’ pay in those companies rose barely 0.3%. In 1965, the chief executives of the top 350 US companies earned salaries 20 times that of their workers. By 1989 that had risen to 58 times, and in 2017 the ratio was 312 times that of workers.

Not surprisingly, compared to the middle-class prosperity that followed 1945, recent decades have seen widening inequality in society. The status quo overturned, capitalism has been hijacked by a profiteering elite. The question is whether society can find an alternative approach that shares the wealth more widely.

Shareholders uber alles

This trend coincided with the emergence of shareholder value as the overwhelming corporate ethos, as the interests of shareholders take primacy over those of other stakeholders in the business. With executives incentivised to maximise profits, meet quarterly share price targets and ensure profits are returned to shareholders, they have been able to game the system to ensure they receive excessive remuneration, while at the same time cutting costs and squeezing wage growth in search of higher profits. British housebuilder Persimmon this year paid its chief executive a £110m bonus, decried by critics as “corporate looting”.

Outsourcing and offshoring have been examples of such cost-cutting, profit-driving initiatives: outsourcing low-skilled work is thought to account for one-third of the increase in wage inequality since the 1980s in the US. The percentage of US workers associated with temporary help agencies, on-call workers, or contractors increased from 10.7% in 2005 to 15.8% by 2015.

Economists have been puzzled by stagnant wages and increased inequality. But as I highlighted as far back as 2007 and repeatedly since, the emphasis on shareholder value has contributed enormously. Management and leadership consultant and writer Steve Denning wrote this year that “shareholder value is the root cause of workers’ stagnant salaries”, with a corrosive effect on societal cohesion and stability – he believes the current rise of populism is one example of the fallout.

Demands for greater profits continue, as companies are pressured by share portfolio managers and activist investors to increase their profitability and share price. Private equity firms, which invest in companies in order to maximise returns, have expanded into many sectors of the economy. Most recently, this has seen the doctrine of maximising profits enter the residential property and home mortgages market.

The pendulum swings back?

Despite the stranglehold of shareholder value on corporate thinking, events suggest the pendulum may once more swing back to favour workers and other stakeholders.

In the US, the government’s Committee on Foreign Investment warned that in its attempt to take over telecoms giant Qualcomm, Broadcomm’s private equity approach could compromise its target’s technological leading position in pursuit of value for Broadcomm shareholders.

In the UK, there was opposition to the takeover of engineering conglomerate GKN by turnaround firm Melrose. Airbus, one of GKN’s major customers, argued that Melrose’s focus on shareholder value and short-term returns meant it might not be committed to long-term investment.

A chorus of voices has emerged advocating alternatives to the short-termist and shareholder-focused model of capitalism. The chief executives of investment and asset managers Blackrock (the world’s largest) and Vanguard, global engineering firm Siemens, and consumer goods giant Unilever have pursued a more stakeholder-centric model of capitalism. 

For example, Unilever by measuring its progress against environmental and social as well as financial targets, and Blackrock by investing in businesses that favour long-term investment over short-term profits. Organisations such as the Coalition for Inclusive Capitalism and the Private Equity Stakeholder Project, have emerged, seeking to ensure that all stakeholders in the business and their interests are included.

Prominent US senator Elizabeth Warren recently introduced the Accountable Capitalism Act to Congress. This would require company directors to consider the interests of all major corporate stakeholders, not just shareholders, in company decisions. It requires that workers are given a stronger voice in decision-making at large companies, such as electing 40% of company directors. As a way of addressing self-serving incentives, executives would have to retain company shares for at least five years after receiving them, or three years in the case of stock buybacks.

Finally, we cannot ignore that business schools played a critical role in how shareholder value emerged as the overwhelming corporate ethos – and they continue to indoctrinate new generations of students with the dogma of shareholder value today. Business school deans and faculty members should urgently revisit their curricula to ensure graduates understand the damaging impact of shareholder value on society and to emphasise alternative approaches.

Almost ten years ago, Jack Welch, who for many years championed shareholder value while at the helm of General Electric, pronounced that:
Shareholder value is the dumbest idea in the world. Shareholder value is a result, not a strategy … your main constituencies are your employees, your customers and your products.
It is past the time that business schools should smarten up, jettison this “dumb” shareholder dogma, and start teaching a version of capitalism less damaging to the interests of society.The Conversation
