Architectural landscape awards: healing gardens, penguin viewing areas and nature trails
The Australian Institute of Landscape Architects recently handed out their trophies for landscape architecture projects at the National Landscape Architecture Awards.
From urban hospital gardens to penguin viewing areas, from gorge trails to cultural precincts, all the projects focused on green spaces and sustainably minded infrastructure ‘to promote health, social and economic prosperity for urban and regional communities’.

National parks are vital for protecting Australia's endangered plants

Norfolk Island, nearly 1,500km from Australia’s east coast, is home to one of the country’s most endangered species, but you probably haven’t heard of it. Clematis dubia, a woody climber with white and hairy flowers, was known to number only 15 mature plants in 2003.
Once common on the island, this clematis illustrates what stands in the way of survival for many of our threatened plants. Around 84% of Australia’s native plants don’t occur anywhere else on Earth.
Threats to our native plants include ongoing habitat destruction, fire, invasive species, more frequent extreme weather events, and declining populations of the animals involved in their pollination and seed dispersal.
Clematis dubia is lucky to call Norfolk Island National Park home. Our national parks are places of beauty and adventure for us to enjoy. They are also a haven for many species.
But life in a national park doesn’t guarantee a species’ survival. Recently we assessed 41 endangered or significant plants that occur in Australia’s six Commonwealth National Parks, to identify ways to help these plants recover.
We found that many of these species don’t occur outside national parks, meaning the parks play a huge role in their conservation. Few of these species have been secured in living plant collections or seed banks, and very few are regularly monitored in the wild.
We have little information on either the impacts of threats or of species biology, which limits our ability to secure these species against further loss.

Clematis dubia lives in small and isolated populations. It faces many perils of modern life, like invasive weeds. We understand very little of its biology, including how its seeds are dispersed, how long it takes to start producing seed, and even how long it lives.
Another plant we assessed was the Graveside Gorge wattle (Acacia equisetifolia) found in Kakadu National Park. A small shrub, less than a metre tall with small yellow flowers, this wattle is listed as critically endangered.
Fewer than a thousand plants are growing in only two locations about a kilometre apart in a restricted area of the park. There is little information on the basic biology of this shrub.
Like other acacias, Graveside Gorge wattle is probably pollinated by, and provides food for, a variety of different insect species. It probably only reproduces sexually and its seeds might be dispersed by ants and probably germinate after fires. The main threat to this species is fires, especially ones that are too frequent or too intense.
As a safeguard against extinction, Parks Australia has collected seed from the Graveside Gorge wattle, which is now stored in the National Seed Bank at the Australian National Botanic Gardens in Canberra.

Seed banking can extend the longevity of seeds to hundreds of years, protecting a species from extinction and helping in its recovery should the worst happen. Germination trials at the National Seed Bank help unlock the often complex germination requirements of different species so that they can be regrown from seed.
As a result of trials with Graveside gorge wattle, the Gardens now has a living collection of this species. In Kakadu, Parks Australia is protecting the two wild populations by planning protective burning to create longer intervals between fires and reduce the likelihood of severe fires.
Protecting plantsSeed banking and living collections are two of the strategies we recommended to safeguard populations of threatened plant species. Some species may also benefit from establishing new populations outside national parks, similar to the management strategies used for vertebrate animals.
We also recommend surveying all endangered plant species in national parks that are not currently part of a formal monitoring program or that have not been surveyed within the past two years.
Finally, realising the gaps in our knowledge of the biology of and threats to many of Australia’s threatened plants, we recommend partnering with researchers and NGOs with restoration experience to draw on available scientific and on-the-ground knowledge.
And what of Norfolk Island’s endemic climbing clematis, Clematis dubia? Along with the low number of individuals, competition from weeds is a major threat to the survival of this species, so conservation efforts by Parks Australia have involved intensive weed control work, particularly to deal with the invasive guava plant.
Recent searches in likely habitat have revealed an additional 33 plants, a mix of adults and juveniles. Happily, new seedlings are now showing up in areas where guava has been removed, improving the future prospects for this species.
The report Constraints to Threatened Plant Recovery in Commonwealth National Parks was funded by the Australian Government through the Threatened Species Commissioner, Gregory Andrews. It was authored by researchers at the Centre for Australian National Biodiversity Research, a joint initiative between Parks Australia’s Australian National Botanic Gardens and CSIRO.

Give millennials a seat at climate talks as a symbolic new country | Letters
Nasa released data earlier this year showing that global surface temperatures across land and ocean in February were a whopping 1.35C warmer than the average temperature for that same month from 1951 to 1980. As the COP22 comes to a close, it’s time we think hard, and think creatively, about the way forward and start preparing for new initiatives. Building on the impressive success of COP21 in Paris, many political and business leaders as well as representatives of civil society seem eager to engage. That is a good thing, but it is not enough.
For better and, increasingly, for worse, our global system of governance rests overwhelmingly on territorial nation-states. In this system, each country’s government represents its own national interest. No one represents humanity as a whole. Such devotion to narrow interests leads to a host of profound problems, well known to economists and students of human behaviour. In various contexts they are known as “the tragedy of the commons”, “the prisoner’s dilemma”, “exporting externalities”, and “free riding”. When asked to act for the common good, nation-states are predisposed to echo Cain’s notorious response: “Am I my brother’s keeper?”

Hollande: US 'must respect climate commitments'
Alan Boatman obituary
My friend Alan Boatman, who has died suddenly in his sleep aged 46, ran his own environmental consultancy, Geo-Sys, in Laos, working on projects identifying and mitigating the impact of resource exploitation in this remarkable area of south-east Asia. Recognising the depth of his experience, the United Nations Drug Control Programme hired Alan to conduct opium surveys in Afghanistan and Laos. At one stage this led to an uncomfortable disagreement with the authorities, as his figures from the field research differed from theirs, but Alan was unmoved and held his ground.
Alan developed a sense of adventure from an early age. He was born in Gibraltar, son of Ian, who worked on overseas projects for Cable & Wireless, and Carolyn, a poet, and was brought up in the Gambia and St Lucia, with two sisters, Kelly and Dale. Alan went to school in Essex, at Holmwood House and Felsted school. He then did a variety of jobs, including working in insurance, in a ski resort in France, as a deckhand on a private yacht and helping to open a night club in Antigua.

‘Grave consequences’ for food supply with wheat production halved since the start of the war and the area of fields planted at an all-time low
Food production in Syria is edging nearer to collapse with wheat production having halved since the start of the war and the area of fields planted now at an all-time low, according to the UN.
The World Food Programme and Food and Agriculture Organization (FAO) warned of grave consequences for the availability of food in the warn-torn region unless immediate assistance is provided to farmers. Lack of food could add to the 11 million Syrians already displaced by five years of conflict, they said.

The world’s temperature is running at 1.2C above pre-industrial levels after another year of record-breaking heat affecting people around the world
Latest figures from the UN’s World Meterological Organization (WMO) released on Monday showed that 2016 would very likely become the hottest year on record. This is a new high for the third year running, and means that 16 of the 17 hottest years on record have been this century.
This year saw searing heatwaves from South Africa to India, Arctic ice reach its equal second-lowest extent and coral mortality of up to 50% in parts of Australia’s Great Barrier Reef.

The UN secretary-general, Ban Ki-moon, said on Tuesday that action on climate change has become “unstoppable“, and he expressed hopes that US president-elect, Donald Trump, would drop plans to quit a global accord aimed at weaning the world off fossil fuels.
At a meeting of almost 200 nations in Morocco to work out ways to implement the 2015 Paris agreement to limit greenhouse gas emissions, Ban said US companies, states and cities were all pushing to limit global warming.

Medina bikes: Africa’s first cycle-share scheme launches in Marrakech
With the potential to curb urban congestion, could a successful trial scheme in Morocco act as a launchpad for borrowing bikes across the whole continent?
Moroccans claim you can identify someone as a true Marrakech local if they own a bicycle. The streets of this north African city were once full of ardent cyclists, but in recent decades they’ve been overtaken by scooters and cars that swarm the city’s congested roads.
Now, French bike company Smoove, is trying to revive Marrakech’s biking culture — and boost sustainable transport — by launching Africa’s first fully functioning bike share scheme in the city. The launch coincided with the start of the COP22 climate conference in the city.

Why our hearts go out to Sherwood's ancient oak
Edwinstowe, Nottinghamshire Perhaps it is a human-sized story – that after 400,000 days on Earth, the Major Oak is still full of life
Although British place names make frequent reference to different tree species, there can be few road signs giving directions to a single specimen. Nor can there be many English woods more steeped in story than Sherwood Forest.
I found a few incidental tales even as I walked up to the Major oak. There were fairy bonnet mushrooms painting their way across a dead stump like Lowry crowds through Salford. There were some last wasps around a waste bin, and wood pigeons so glutted on acorns their crops bulged. A robin laced its sad song among the birches, but sadder still was a bench with the following inscribed across its seat: “Abby Louise Hucknall – Missed So Much.” An emotional counterpoint came amid much open-armed laughter from the children playing along a Halloween-themed trail.

15 November 1927: A central authority to control inland waters must be a priority for the government
The appointment by the Minister of Health and the Minister of Agriculture and Fisheries of a representative Joint Advisory Committee under the chairmanship of Sir Horace Monro “to consider and from time to time report” upon the pollution of rivers and streams and suggest appropriate legislative or administrative measures to reduce what is admittedly a growing evil is welcome, though tardy, news.
Such administrative bodies as the Mersey and Irwell Joint Committee, the West Riding of Yorkshire Rivers Board, the Ribble Joint Committee, the Thames Conservancy Board, and other similar bodies have long been doing excellent work. But the problem is a national one. A strong deputation, representing numerous interests, recently urged upon the Government the immediate need for “a central authority to control inland waters.” It was able to support this demand by quotations from Royal Commissions, Select Committees, Departmental Committees, and scientific authorities for a period of more than half a century.
