The changing size of mother whales is being tracked after the southern white whale came back from the brink of extinction

After being hunted to near extinction and threatened with climate change, drones are giving southern right whales in the Great Australian Bight a much-needed health check.

Sponsored by WWF-Australia, researchers at Murdoch University are measuring the size of individual whales and monitoring how that changes during the calving season, with plans to track their weight each year.

Relentless poaching is decimating Africa’s elephants. But the world’s largest land mammal could have a powerful, new champion if Hillary Clinton becomes president of the U.S.

When asked by Ellen DeGeneres what her spirit animal is, Hillary Clinton had a surprising answer: the elephant.

Although the symbol of the GOP, Clinton spoke on the Ellen DeGeneres Show this May with rare passion about the need to protect real elephants from a poaching crisis that has killed at least 110,000 of them over the past decade, pushing the world’s largest land animals – especially forest elephants – closer to extinction.

Findings highlight how US is in grip of significant environmental changes driven by warming temperatures in different ways to processes that fuel hurricanes

The frequency of floods of the magnitude of Hurricane Sandy, which devastated parts of New York City in 2012, is rising so sharply that they could become relatively normal, with a raft of new research laying bare the enormous upheavals already under way in the US due to climate change.

These findings and two other fresh pieces of research have highlighted how the US is already in the grip of significant environmental changes driven by warming temperatures, albeit in different ways to the processes that are fueling hurricanes.

Global oil giant BP has announced it will cease controversial exploration off the coast of South Australia.

The New South Wales government’s U-turn on its greyhound industry ban says as much about the weak calibre of some politicians holding high office as it does about their subjugation to the media, which has relentlessly pilloried Premier Mike Baird about the ban since it was first announced.

Facing declining popularity, Baird appears to have capitulated to the media to try to win public support, and avoid discontent within the Nationals party in New South Wales. This is unlikely to succeed: according to a recent RSPCA poll, 64% of the public support the ban.

The ban was announced in July to come into effect in 2017, following a review of the state industry led by Special Commissioner Michael McHugh.

So what does the backflip mean for greyhounds?

What will happen to the industry now?

In a media statement, Baird and deputy premier Troy Grant announced a suite of changes that would allow the industry to continue.

These include:

• Life bans and increased jail terms for live baiting

• A new regime to register greyhounds for their entire lives

• A new independent regulator with “strong new powers” to ensure transparency and accountability

• Fresh resources for enforcement and prosecution of wrongdoers and new resources for animal welfare.

Former NSW premier Morris Iemma will chair a Greyhound Industry Reform Panel that will determine the new rules, and will involve the RSPCA, the greyhound industry and government representatives.

The greyhound industry reportedly proposed a number of changes to overturn the ban including a cap on breeding, and reduced numbers of tracks and races.

Limiting the number of bitches breeding in NSW will do nothing to reduce the scale of the industry. Dogs could just be brought in from interstate, and it will be difficult to police this movement.

The sops to the animal advocacy bodies are that they will receive more money to deal with animal cruelty and there will be increased support for rehoming greyhounds in NSW. But as a recent study from my group shows, greyhounds have significant behaviour problems in the home, due no doubt in part to their traumatic upbringing.

Industry on the way out

In an industry already declining, these measures merely reflect the need to curtail its scale in the event of declining attendance and interest. Greyhound racing is now banned in 40 US states. Just 19 tracks remain in six states. Worldwide the industry is only maintained in a handful of countries.

There are a number of reasons why the public has turned away from racing. Like other animal (and human) competitions, these games have been tainted by use of drugs and other uncompetitive practices, such as live baiting in greyhound racing.

Top greyhound trainers earn earn up to A$5 million per year. There is declining public appetite for an industry that generates huge profits for a select few.

Then there are the ethical considerations. At least 50% of dogs are culled because they are too slow. The industry is clearly on the road to self-destruction in terms of its public appeal.

Greyhounds have abnormally large hearts, high blood pressure and a predisposition to gastric torsion and bloating. Like racing horses, the public does not gain any pleasure in seeing such animals win races when it knows that it is simply due to physiological abnormalities on the part of the winner.

Public interest in such sports is changing from “who is the fastest” to a celebration of giving everyone a fair go, to enjoy taking part, in line with the widening circle of compassion that has been increasingly sweeping through human society for at least 200 years.

Out of step

The review of the industry advised that:

Given … the highly entrenched nature of live baiting as a traditional training method, there is a very real risk that, once the harsh spotlight of this Commission is removed from the industry, the practice of live baiting will thrive once more. It is imperative that regulators take all available steps to try to ensure that this does not occur.

For live baiting, the review recommended lifetime bans for any trainer found to be involved in the practice.

Overall, the review recommended the government consider banning the industry, or, if it was to continue, make a number of changes to tighten regulation such as lifetime registration, improved reporting and oversight.

Mike Baird was bold enough to ignore his government’s earlier support for the industry, and was evidently influenced by the widespread evidence of cruelty in the industry.

The evidence of this very detailed investigation now lies in tatters.

This is out of touch with the attitude of the general public, the majority of whom want to see the welfare of animals managed better at a government level.

Australia should be at the forefront of world leadership in celebrating the opportunities through sport for those less advantaged, the aptly named underdogs in society, to be given a fair go.

Instead of racing greyhounds, why aren’t we supporting the public to bring their elderly, overweight, or otherwise less-than-perfect pooches to meet other dogs and have a trot around the track, to the delight of onlookers?

At least 1,000 people were killed when Hurricane Matthew battered the Tiburon peninsula in Haiti last week, destroying houses and displacing tens of thousands.

A humanitarian crisis is now unfolding for the survivors, with the Pan American Health Organization warning of a likely cholera surge in the country due to severely damaged water supply and sanitation systems.

Several other Caribbean island states have been affected, including the Dominican Republic, Jamaica, Barbados, Saint Vincent and the Grenadines, and Cuba, as well as the United States.

In 2011, one of us (Jason) led a team to Haiti’s capital Port-au-Prince to contribute to the reconstruction effort after the devastating 2010 earthquake. The team worked particularly on the provision of housing.

In all interactions, the team encountered a local community that was honourable, industrious and kind. This perception is confirmed by those who have spent time on the ground after Hurricane Matthew.

But, as is common in the media and institutional narrative following disasters, prejudices and preconceptions abound. Following the earthquake, the Haitians were portrayed as weak, dependent, corrupt and lawless victims. The international community intervened, amid a global outpouring of grief, support and solidarity.

Five years later, destruction and suffering in Haiti is again making headlines. Why is history repeating itself?

Unnatural disasters

According to the United Nations Office for Disaster Risk Reduction, disaster risk is a function of hazard, exposure and vulnerability. It is normally expressed as the likelihood of deaths, injury or loss of infrastructure for a specific period of time. This suggests that disasters are the product of the human condition.

But other experts describe disasters as “manifestations of unresolved development problems”. Therefore, disasters are not a natural phenomenon. Humans play a central role. As a result, a natural hazard such as Hurricane Matthew impacts each country in its path differently.

Countries, regions, people groups and individuals are distinctly affected by hazards, mostly based on pre-existing vulnerability. While most scholars agree that there are particular vulnerabilities for specific hazards, some argue for “a generalised vulnerability that affects the poorest of the poor and most marginal in all parts of the world”.

In Haiti, many aspects of risk and vulnerability have very deep roots in colonial history. The structural injustice existing in society has been compounded by recent trends in international economics. These have worked to exacerbate widespread vulnerability and exposure.

The status quo has failed Haiti

The earthquake in 2010 resulted in 222,750 deaths, 300,000 injuries, 1.5 million displaced people, and more than 3 million affected in total. Most of the built environment in Port-au-Prince was destroyed, as well as its basic services and infrastructure.

In August 2010 the United Nations tacitly admitted blame for the cholera outbreak that occurred after the earthquake. However, it later invoked absolute immunity.

Cholera has claimed more than 9,000 lives and infected more than 720,000 people in Haiti since 2010. And the failure to contain and eradicate the disease has manifested into the current crisis, with a surge of infections in the areas hit hardest by Hurricane Matthew due to poor water and sanitation.

Little of the US$13.5 billion pledged by the international community after the earthquake ever made it to Haiti’s people or into its economy. Most of it (94%) went to private contractors, donor nations’ own civilian and military entities, international non-government organisations, and UN agencies.

Investigations have revealed that the actors of predatory capitalism rushed to secure quick and easy profits in the wake of calamity. This has helped to prevent any serious effort to address disaster risk by sidelining local stakeholders.

Under the guise of goodwill and solidarity, the United States has officially supported what journalist Antony Loewenstein calls “the latest incarnation of a tired model that failed to deliver long-lasting benefits to locals, but instead delivered cheap labour to multinationals”.

No argument for skills development and employment opportunities can really excuse abusive labour practices. In Haiti, these simply reinforced underlying vulnerability and made a mockery of the commitment to “build back better”. In reality, the United States’ interests have been protected and served in Haiti for a century.

Reducing disaster risk in an age of uncertainty

Put simply, we are creating new risk faster than we are dealing with the existing risk. James Lewis and Ilan Kelman warn that:

…without tackling all vulnerability drivers – that are the roots of [disaster risk creation] – the conditions of [disaster risk creation] will continue to prevail over attempts at [disaster risk reduction].

We continue to demand conformity to orthodox ways of thinking about economics, development, governance and society that have locked us into destructive pathways. Disaster risk is socially-constructed and we must propose solutions that do not ignore root causes. This means providing empowerment and autonomy to communities which live in at-risk areas, including access to resources, education, livelihoods, and health.

Jocelyn McCalla, of the National Coalition for Haitian Rights, asserts that:

Hurricane Matthew has disrupted the expected course of events. We should not seek to put Haiti back on course. We need to change course altogether, use disruption to identify another course of action in consultation with Haitians.

We know that development, imposed by external forces that exploit the local labour force is not in the interest of the marginalised. A failure to respect human rights, local needs, the environment and human-environment relations simply creates disaster risk.

A shift towards truly transparent, democratic and participative practices is necessary. We must acknowledge the role of corporations, governments, NGOs and even United Nations agencies both in creating new risk and preventing the reduction of existing risk. Otherwise our well-meaning efforts to help Haiti now and in the future will leave us asking the same questions when disaster next strikes.

New technology is a significant step towards the creation of virtual power stations that would enable smarter electricity use by homes and businesses

Data has been transmitted across a national electricity grid for the first time, in what could be a significant step towards the creation of virtual power stations, where many thousands of homes and businesses combine to manage electricity use more smartly.

The new technology could lead to lower energy bills for consumers who allow small variations in the energy consumption of their appliances, such as water heaters or freezers.

Waltham Brooks, West Sussex Around the pool’s edges, snipe drill into the mud as the sun sinks towards the horizon

The air is noticeably colder, and the blue sky above the Brooks seems empty. The swallows and martins that had been following the river Arun south to the sea, in an almost continuous stream for the past month, have gone. Only jackdaws and rooks fly over, croaking to each other, heading towards the woods and back to their evening roosts. The sinking sun casts a warm glow across the large pool, where recent arrivals – a flock of wigeon – are paddling, dipping into the muddy water to feed alongside the regular mallard and shoveller.

Around the pool’s edges, snipe bob their dark brown-striped heads up and down, drilling their long bills into the mud in hurried sewing-machine movements. More snipe sit by the reeds, preening or sleeping, their heads turned and their bills tucked into the feathers on their backs. I walk on through the wet grass, listening to the cries of the coot, water rail and ducks, and watch my footing.
