DO NOT BLAME NATURE FOR DISASTERS: ALLOW MANGROVE FORESTS TO RECOVER

Allowing mangrove forests to recover naturally result in more resilient habitats that benefit both wildlife and people, say conservationists

Reproduced from BBC NEWS - Environment


In Indonesia, a Wetlands International project uses permeable dams to restore sediment needed for the trees to grow.
The charity says early results suggest "ecological restoration" is more effective than planting programmes.
More than half of the world's most at-risk habitats have been felled or lost over the past century, UN data shows.
Mangroves are a group of about 80 different salt-tolerant species of trees that are able to live along the intertidal zones of coastlines in tropical and sub-tropical regions.
The characteristic root systems of these trees allow them to withstand the ebb and flow of daily tides. The roots also act as buffers, slowing the flow of the tidal waters, allowing sediment to settle and build up as nutrient-rich mud.
The unique habitats provide valuable shelter and breeding sites for fish, as well as stabilising coastlines, reducing erosion from storm surges and tsunamis.

Life-saver
A report by the International Union for Conservation of Nature (IUCN) shortly after the 2004 Asia tsunami, which killed more than 200,000 people in nations lining the Indian Ocean, highlighted how in-tact mangrove forests provided protection to coastal communities.
It reported that two people were killed in a Sri Lankan village with dense mangrove and scrub forest, but up to 6,000 people lost their lives in a settlement that was no longer protected by similar vegetation.
Following the 2004 tsunami, the importance of robust and resilient mangrove forests became widely recognised, explained Femke Tonneijck, Wetlands International's programme manager for coastal wetlands.
"This resulted in many mangrove restoration efforts around the world, many of which were implemented through planting programmes by NGOs, governments and business," she said.
"Now we are seeing that many of those planting efforts are failing, and there are a number of reasons for this. 
"One of the most important reasons is that there is a wrong species-to-site match because mangroves have a natural [gradient] from land to sea, in which there is a mix of species that are best adapted to the level of salinity, wave exposure and submergence. 
"This is why we now focus more on ecological mangrove restoration," Ms Tonneijck told BBC News.
She said researchers had been carrying out a series of studies on this approach to conservation and it had been shown to deliver "much better results".
"This is because if you have a mix of natural species, ages and root types, as well as different types of fruit, fodder and timber, the diversity makes the system more resilient, as well as a forest that offers multiple benefits to a diverse group of stakeholders, as there are different species of fish taking shelter in the different root systems," she added.
However, planting programmes still remained popular because many schemes, often government-funded, measured success on the number of trees planted rather than the longer term survival rate.
"Also, there is no measurement of ecosystem services returning, such as coastal protection, and this may give people a false sense of protection," Ms Tonneijck warned.

In 2011, Wetlands International was invited to undertake a ecological mangrove restoration project in Central Java by the Indonesian government's marine and fisheries department.
Two villages in the area had been lost and the sea was encroaching inland up to three kilometres, destroying arable land.
Ms Tonneijck explained how the team restored the conditions needed for the mangrove to return to landscape.
"Working with Deltares, the Dutch knowledge institute, we were inspired by Dutch and German marshes where land was regained by putting permeable dams in place," she recalled.
"These permeable structures let waves pass through with sediment and behind the structures the sediment can settle. Once it had settled then the mangroves were able to come back into the area.
"We started first with a small pilot, and as the sediment trapping worked really well, we decided to set up a larger project that was supported by Dutch funds and the Indonesian government as well."
Wetland International's Building with Nature programme is now looking at restoring the "mangrove greenbelt" throughout the district.
"In the area where it is eroding, we are applying these permeable dams and we have already placed two kilometres of them," Ms Tonneijck revealed.
"As well as the mangroves slowly coming back in, we are also seeing that people are becoming very enthusiastic and they really want to do something - people immediately want to start planting as soon as there is sedimentation. 
"So we have started a dialogue explaining why we are preferring to wait for nature to come back.

SUPERBUGS ANTIBIOTICS RESISTANT WILL BE EXTERMINATED IF...KEEP OFF FACTORY FARMED MEAT!!!

All 193 UN states will sign a declaration today to fight the spread of drug-resistant 'superbugs', writes Alastair Kenneil. The problem is often blamed on overprescription of antibiotics by doctors. But that's to ignore the massive use of antibiotics on animals in factory farms, both to prevent infection and to assist weight gain - turning farms into superbug breeding centres.


For decades factory farmers have been pumping antibiotics into livestock to compensate for inhumane and disease-inducing conditions. Now, bacteria are fighting back.

A new ground-breaking study of factory farmed UK supermarket pork and chicken has found that 71% of the samples were contaminated with antibiotic-resistant E. coli bacteria that cause life-threatening kidney infections and blood poisoning. The figure for just pork was alarmingly 63%.

Pigs in factory farms are so overcrowded, stressed and unhealthy they have to be routinely given antibiotics even when no disease has been diagnosed in any of the animals. What's more, drugs classed as ‘critically important' for people may be used.

In the EU, from where 54% of the pork consumed in the UK is imported, factory pig farms can keep pregnant mother pigs confined in steel cages for 20 weeks a year. In UK low welfare farms, including Red Tractor, this is allowed for 11 weeks a year when she is feeding her piglets.

The high levels of stress from having to endure weeks of this torture makes her vulnerable to injuries and disease.

To achieve maximum weight gain piglets in factory farms can be taken away from their mothers when they are only 21 days old, too early for their immune systems to develop properly. This means they have to be routinely given antibiotics as an integral part of the production cycle.

Intensive farms 'breeding' antibiotic-resistant bacteria

Just as doctors strive to reduce antibiotic use in the surgery, so farm use is increasing. Around a quarter of all antibiotics prescribed in the UK are given to pigs in factory farms. This routine misuse of antibiotics means that bacteria become resistant, bringing us closer to the end of antibiotics as a cure for an increasing number of human diseases.

The study, commissioned by the Alliance to Save our Antibiotics and conducted by Dr Mark Holmes from Cambridge University, is the first study to examine UK-origin retail meat for resistance to a wide range of key antibiotics for treating dangerous E. coliurinary-tract and blood-poisoning infections in people.

The study tested 189 samples of low welfare, UK-origin pork and chicken meat from the seven largest supermarkets from across the UK (ASDA, Aldi, Coop, Morrisons, Sainsbury's, Tesco and Waitrose).

Across factory farmed pig and chicken meat from all these supermarkets, the study found E.coli bacteria resistant to three highly important antibiotics for treating E.coli infections in people.

The research found soaring levels of resistance in chicken meat, with a staggering 24% of chicken samples testing positive for ESBL E. coli, a type of E. coli which is resistant to a family of antibiotics classed as ‘critically important' for people (the cephalosporins). These antibiotics are widely used for treating life-threatening E. coli blood poisoning in humans.

On 19% of pig and chicken meat, E. coli bacteria showed high levels of resistance to the antibiotic Gentamicin, which is of vital importance in treating serious urinary tract infections in people. Resistance to another essential antibiotic, Trimethoprim (which is the most widely used drug for treating lower urinary-tract infections in people) was found on 51% of pork & chicken samples.

The findings provide further evidence that the overuse of antibiotics on British farms is undermining the treatment of dangerous E. coli infections in humans.

Exposing humans to potentially fatal infections

This is of huge concern, as the number of serious E. coli infections is at a record high and increasing every year. E.coli is by far the most common cause of urinary tract and dangerous blood poisoning in humans, and can also cause meningitis. These kinds of infections can be fatal if they do not respond to antibiotics.

But the last 25 years has seen a steady increase in resistance to some of the most important remaining antibiotics which can treat these infections. No new antibiotics for treating E. coli infections have been discovered for over 35 years.

Increasing resistance is leading to record levels of E. coli blood poisoning. Figures we have assembled show that in 2015 there were over 45,000 E. coli blood poisoning infections in the UK.

The number of blood-poisoning infections has increased every year since 2000 (when it stood at about 12,000 or so), and is increasing by about 2,000 each year now. E. coli is by far the most common cause of blood poisoning nowadays, causing more blood poisoning than the next four bacterial causes of blood poisoning combined.

Meanwhile, many important antibiotics - including a number of those examined in the study - are used in far greater quantities in livestock farming than in human medicine, often given to whole groups of (mostly healthy) animals.

This systematic overuse of antibiotics in factory farms is fuelling the emergence of resistant bacteria. These superbugs can then pass to humans through the environment, or via meat that we buy in the supermarket.

The antibiotic resistance crisis is predicted to kill one person every 3 seconds by 2050. Over a third of these deaths will be caused by drug-resistant E. coli. This catastrophe is now unfolding before us.

The silience of the supermarkets

Supermarkets have remained too silent on this issue. While our vital drugs fail, they continue to permit unacceptable antibiotic use in their supply chains.

Supermarkets must now take share the responsibility for tackling this crisis by banning the routine preventative mass medication of groups of animals, dramatically curbing farm-use of the ‘critically important' antibiotics in their supply chains, and setting specifications around good animal husbandry.

Animals should - and can - be kept healthy through good husbandry and welfare, not through routine medication. It's time to stop sacrificing our animals - and our antibiotics - for cheap meat.

As farmers strive to compete with cheap imported pork, many farmers break EU and the UK regulations by depriving the growing pigs of straw (or other bedding material) to reduce labour costs. Crammed into small pens without the ability to express their natural instincts to root in straw for food and play with, pigs are stressed and fight thus increasing their vulnerability to disease.

Without straw the pig waste can more easily drop through the concrete floor slats into tanks underneath. The effluent is spread onto fields, sickening local residents with a toxic stench of ammonia and a cocktail of other gases and disease-causing bio aerosols.

This effluent inevitably leaks into watercourses, killing fish and other wildlife in rivers and the sea. In contrast, pig waste on outdoor farms, whose certification system demands limited pig numbers, nourishes the soil and forms part of the crop cycle that grows the pig feed.

Competing with imports is driving UK farmers in to a downward spiral where farms have to consolidate and reduce labour or go bankrupt. In the past 15 years the UK pig herd has dropped by half, while 70% of the imports have been raised in conditions that are illegal in the UK.

Join the growing movement for high-welfare farming!

The good news is that conscientious consumers are buying pork from high welfare farms. Today 25% of UK pork has been raised either outdoors, or indoors with plenty of straw and space to move around, where the pigs are happy and healthy and rarely, if ever, need antibiotics.

The solution? Of course we must back today's UN initiative to tackle the problem of microbial resistance on a global level. But we can also act closer to home and join the growing movement against factory farming by only buying meat from high welfare farms.

How? In supermarkets, only buy pork with the labels RSPCA Assured, Outdoor Bred, Free Range or best of all, Organic. Ask for high welfare pork in butchers, farmers' markets or online.

It doesn't cost much more - four sausages from a factory pig farm cost the same as three sausages from a real farm where pigs are healthy and free to move around. Reducing our meat intake also helps avoid obesity, diabetes, heart disease and certain types of cancer.

We can all give up half a sausage and help bring an end to pig factories, for our health and humanity's sake.
