This is a long-term project. Our hope is that with help the number of destinations will grow fast. For now, I have created this page. Generally, there is a future places section on all country pages, so these can also be accessed from there. The aim here, is for myself (and other people as the site grows) to be able to write pages about specific destinations, before we have any links to help you with your wild travel in that destination.
Electrical and heat battery news roundup
In Finland, a so-called sand battery (it is actually full of crushed soapstone) has been built, which is capable of storing around 100MW of heat. The crushed soapstone is a by protudct of a fireplace production factory nearby. It is true that this heat battery is large, with a height of around 13m and width of 15m, but it can in theory be buried in the ground. It takes 2000 tonnes to fill this heat battery, but this is just 40 waste trucks worth.
It will serve as a thermal battery, with pipes running through it. It can be heated in the Summer when there is cheap or even free power, and then water run through pipes in the material can extract the energy in winter, powering a district heating network – greatly reducing the emissions from heating houses in the whole area (it is estimated that it will reduce emissions by 70%)
The Soapstone leftover, was a wasted product, and before was just thrown away, so this is a far better use. This “sand” battery can hold heats of around 500 degrees for months if required, and is thought to completely eliminate the need for oil in the network heating system. it equates to roughly 1 month of heating requirements in summer, and 1 week in winter. Costing around $200,000, compared to $1,600,000 for the equivalent lithium battery, it is a good deal. While it is true that it would take around 30 of these to keep the town going for a year and it only supports 100 houses and a public swimming pool, but there is huge quantities of similar waste created around the globe, and therefore is capable of doing far more than one would think.
Simulations of the same idea, in Seoul have suggested at up to 39% savings. It is thought, that as the deployment of solar increases, there will be huge amounts of excess power to be pumped into things like this. Some countries have wonderful quantities of excess electricity in the summer, and while we need to ramp up the quantity of solar wild and other zero carbon electricity, this gives us a route to a zero carbon world.
UK scientists created the worlds first diamond battery, capable of giving power for thousands of years. It is made from synthetic diamonds, which contain a radioactive element called carbon 14. The battery makes electricity from this radiation, much in the way that solar panels work. This battery would still be at 50% power after 5000 years. From devices that need powering in your body, to deep in the sea or in space.
At the end of their lives, these batteries can go back to the manufacturers to be recycled. There is much work being done on this, not least looking at other radioactive elements, to increase the power output.
Carbon nanotubes store triple the energy of lithium batteries. New research shows that twisted nanotubes can store high densities of energy – triple that of lithium weight for weight. It is thought that these could power things like medical implants. Of course, this is great, though only adds to the potential long list of things that nanotubes can do if we can learn to reliably create them in the future. In bigger sizes, it is calculated that these carbon nanotubes can store 15,000 times more per unit mass, than steel springs.
These are both areas which I write on, regularly, so check back for more news. I should also note, that these roundup articles should allow a return to focusing on wildlife rather than clean tech soon.
Deforestation and palm oil stories: Deforestation is not a desire, there is demand for what is done with the land
The problem with stopping deforestation, is that for the majority of the world we are far removed from rainforests (from where I sit in the UK, I would have to travel 3250km (over 2000 miles) to the nearest rainforest, which is an area on mainland India). Indeed, rainforest is generally something that only survives in developing countries.
This means that, for most people, they either live far removed from the rainforest, and so cant see it impacting them, or they live near a rainforest, but are struggling to provide for their family and those around them. It is quite true that many people in both the first and third world would like the rainforest to survive – indeed, should you talk to people in the west, many are very worried about the survival of the great apes, who are rapidly loosing land.
The problem is simple. Those living in the third world are living hand to mouth, so unless they work in tourism, the rainforest is often an inconvenience that makes life harder.
In 2023 a total of 6.4 hectares of forest were destroyed – more than 25,000 square miles. However, more concerning is the fact that 62.6 million hectares of forest (almost quarter of a million square miles) was degraded – for road building, logging, and forest fires. Degraded land is often less good for carbon storage, as well as conservation of the worlds wild species. It is often, then not long, before someone comes along a removes the rest of the plants so that the land can be used for something else.
And what was this deforestation for (other than logs)? Beef, soy, palm oil paper and nickel.
The Brazilian Amazon is one of the bright spots, where since the election of Luiz Inacio Lula da Silva, deforestation has fallen 62%. Unfortunately, in the same time period, Indonesia’s deforestation is up 57%
It seems hard to see how the world will meet its goal of cutting deforestation to zero by 2030 as most countries have pledged. Also, despite reductions in deforestation, the Amazon has had one of the hardest years in terms of forest fires – something that only gets more likely as rainforests are lost, and climate change increases the temperature in many parts of the world. It is a sad fact, that there is often not a great deal of temperature difference between a rainforest which is functioning, and one that dries out and becomes a fire hazard.
Having said all this… a study in Indonesia has found that controlled low-intensity logging doesn’t have to negatively impact a forest in terms of carbon storage or food availability – this in turn means that much wildlife can survive.
The problem often is that if the land is in private hands, then low- intensity logging is not going to happen. If the landowner has decided to deforest, they will raze the land. In national parks, in theory low intensive logging would be possible, but this would require people to control the logging, and this is the issue that we have in the first place. Unfortunately, despite the pledge by 140 countries, deforestation is coming back.
In a related subject, the Indonesian president Prabowo Subianto has stated that palm oil expansion won’t deforest because palm oil has leaves. There are many issues with this, but perhaps primarily amongst them, when forests are cut down, they are usually replaced with grass lands for grazing cattle – these are also covered in leaves. This is obviously stupid – it may well be a better thing, that the rainforest is going to be replaced with plantations, but it has been shown that palm oil plantations take up a tiny proportion of the carbon that rainforests take up.
In another article, there was a finding that macaques living in palm oil plantations have an alarming infant mortality. Unfortunately, these macaques are not unique in being threatened by palm oil, but others include orangutans, elephants, tigers, pangolins, bonobos, and Irrawaddy dolphins.
While palm oil may be a better vegetable oil than other crops, it still looks like it will lead to us loosing most of our rainforests, unless a grip on this is found.
Demonstrating their high intelligence, monkeys took up stone tools during covid, when tourist handouts stopped
Scientists and researchers have been able to watch the introduction of a new skill, but this one arrived very fast, on some of the islands within Thailand. This perhaps shows the intelligence of the Long-tailed macaques in question rather than being any sudden change. The requirement to develop the skills occurred because the arrival of COVID meant that tourists, who often give food to the monkeys, dried up almost overnight.
While many of these tourism activities were (and likely are) labelled as eco-tourism, clearly there needs to be a big change, if humans had such a big impact on these monkeys wild behaviour.
Demonstrating their high intelligence, monkeys took up stone tools during covid, when tourist handouts stopped
Monkeys around the world often come to rely on tourist handouts far to readily. Monkeys on some of the Thailand islands rapidly developed the ability to use tools, when the tourist handouts ended as a result of covid.
This shows their incredible intelligence and their ability to adapt rapidly, and it also shows how much easier tourists are making the lives of some wild animals (while at the same time making life for others hard or impossible).
It also asks the question – is taking food from tourists tool use? If so, there are a very wide range of species that use a tool, if one which requires very little intelligence on the part of the animal
If octopus are smart, should we farm them for food?
Octopus can appear extremely intelligent, as a result of their intelligence being quite specific. They are superb problem solvers (and are capable of watching other octopus and learning through this), very capable escape artists (in an aquarium, an octopus was shown leaving its tank, and entering the neighbouring tank to catch fish at night) and have a phenomenal ability to change their body colour and texture to match the background.
Their brain setup, is completely different to mammals similar to humans, as their brain is spread through their body.
It should be noted, that an octopus can grow at 5% a day, which means that they are a very efficient way to create meat. Still, I would be very hesitant to eat them regularly (and obviously, any octopus that you might consume must come from populations that are being harvested in sustainable ways).
I would argue that farming highly intelligent octopus for food may not be great, but is much better than hunting wild octopus for food.
What do you think?
Sweden began its annual wolf hunt on the first day of the year
I have talked about about wolf hunts in Sweden in the past. They recently reduced the required minimum population from 300 wolves down to 170 – given that the 300 was worked out scientifically (and most people believe that this population is way too small anyway).
The current population is 374, with a target kill this year of 30. The intention is to kill 5 families. However, this number of wolves is certainly not good. Sweden is a country of similar size to France, and much of the country is wild so a far larger population would be capable of not impacting humans.
Campaigners are claiming that this is illegal (and it is hard to argue them) as the Berne convention states that protected species cannot be caused to have their population fall below sustainable numbers – 170 is well below this level, and indeed 300 is likely only healthy long-term, because of wolves crossing over the border from Russia.
I have been lucky enough to see 2 Swedish wolves, one from a bear hide, and the other while watching a group of Elk. Well structured, the wolves in Sweden could be a huge positive for the country, particularly tourism and one would think would be important as Sweden has positioned itself as an ecotourism hotspot.
Without a change, they will destroy this early market which is good for the country.
US has tightened African elephant trophy import rules but stops short of banning
Elephants hunting used to be a common activity. This was banned in Kenya in 1973 and in Botswana in 2014. The trade in Elephant parts was banned in 1989.
For many years, however, conservationists have called for rich countries to ban imports of hunting trophies on a country by country basis. This is for a simple reason – a reserve like the Kruger, has a real issue with a growing elephant population, yet at the same time Nigeria has only 400 elephants left. Tanzania has seen a reduction of elephants of 63%, while Mozambique has seen a reduction of 34%.
This new ruling suggests that imports are only allowed from populations which are large enough to support the loss. Now, I would be interested as to how this is worked out. For instance, could I buy a tiny parcel of land, on the edge of a large reserve, and allow any elephants that step on my land to be hunted?
- Somewhere like the Selous game reserve, would in theory be acceptable for elephant hunting. If we go back to the 1976 there were approaching 109,000 elephants. However that population is now thought to be around 13,000 – hunting should be banned until the population has recovered. If a hunting reserve cannot afford to police well enough to eliminate poaching, it should not be allowed to hunt (the number of poached and hunted elephants must be below safety levels.
- The Serengeti ecosystem also does not have a large elephant populatino so cannot allow hunting
- The African forest elephant is considered critically endangered, so none of these elephants should be hunted
Wildcat kittens born outside captivity in Cairngorms
Wildcats are native to the UK, but have been pushed to the brink of extinction by hybridisation with native cats – which come from the wildcats from places like Israel in the middle east. As a result of this, as well as trying to remove the feral domestic cats, and their descendants, they are trying to create pockets of Scotland, which would allow these cats to recover.
The natural behaviour of a British wildcat when meeting a feral cat, is to kill it. However, as these animals become rarer, even rare breeding events, can threaten the survival of the whole species. This behaviour also means that with careful planning, we should be able to reintroduce them into other parts of the country. There are a range of other wild predators lost over the last couple of millennia – and I hope to see the others return, but it is thrilling to know that a wildcat is once again living and breeding in its native habitat of the Scottish mountains.
These wildcats are thought to be the first born wild in Scotland for 5 years, after 19 wildcats bred in the Highland wildlife park, were released into the Cairngorms national park.
Near-extinct Siamese crocodile making a recovery
The Siamese crocodile is recovering in Cambodia, with 60 hatched babies this year – more than at any time this century. Five nests were found by locals at the end of June with the eggs that resulted in these crocodilians. Thought extinct, until being rediscovered in Cambodia they have made an impressive recovery since 2012 when the project started, with 196 of this species returned to the wild in the last dozen years.
Local community wardens regularly cross the mountainous area, to check on them. In recent times, they have been observed in new territory, suggesting that their population is growing again naturally.
