I love that Magawa's wikipedia article is structured just like a human: Early Life, Career, Retirement and Death.

A few weeks ago when "Croatia declared free of landmines after 31 years" was posted here (https://news.ycombinator.com/item?id=47189535), I rabbit holed wikipedia about landmine-sniffing animals. It's such a fascinating topic.

You can teach a kid to change a tire without saying a word. It’s the same thing. Rats are very smart and very social. Rats that were good at teaching Rathood to their little ones had more that survived.

Put food in a maze and I’m sure rats would teach other rats how to get it. I expect this is similar.

Rats are intelligent social mammals. They teach by actions. Imagine training a dog. You have two dogs, one trained and one not. You say "sit" and the trained dog sits and you give it a treat. The non-trained dog will quickly pick up on that.

One demining expert claims that the rats are actually no good, but the charity persists with them anyway: https://nolandmines.com/APOPO%20rats.html

I too have no expertise here, but I've known quite a few rodents. So... my amateur take:

I do not think that the area would necessarily need to be cleared of debris first. Rats can get places people would never imagine they could quite easily.

What I did find to be consistent with rodents is the difficulty in getting them to use set search patterns and such. Rodents go where and how rodents go, and I've never found it possible to teach them set routes. They get a whiff and tend to go right at whatever they smelled in contrast to dogs who can be taught to take set routes/patterns.

The "distance from the nose" wouldn't matter. Rodents can often smell stuff that's around a mile away... a few inches of dirt (most landmines are under fewer than 25cm of dirt, anti-tank mines under fewer than 30cm) wouldn't be sufficient to deter them.

Reliably signaling humans depends upon the particular rodent. Rodents have personalities, and they will often make very particular signals to their people in response to particular things. Reliably enough to bet a life on it? Not sure, but I don't think they'd be terrible in that regard.

This is the most technical post, and it will go almost unnoticed.

A cool story about a rat or a dog draws more attention than mines which were missed and maimed people years after searching the field.

Anyways, the author of that piece is a little mad, but in the sense that it is worth serious consideration. TLDR: the rats aren't cost effective and, worst of all, haven't scientifically proved to be effective.

There’s no point to be sad: even trees get remembered and honoured. Human’s humanity have no such "compassion contingent”: loving a new child doesn’t take the love out of the precedents.

Some antispeciesist (and others) argue that giving more compassion to animals is a step to develop one’s compassion to others being, hence being nicer to others humans. On the opposite: accepting an horrendous practices toward non-humans animals makes ones more prone to accept horrendous practice toward humans.

I agree. However, you get insane push back the second you start to mention veganism. And yes, that is a luxury and there large parts of the world where that's not an option, but if you're reading this comment you probably could survive without eating meat.

Yep. Another great example of this is any discussion where datacenter resource usage gets brought up.

Also, I personally think framing it as a binary or quasi religious decision is counterproductive.

I was vegetarian for some years, before ultimately deciding I just run better on an omnivore diet. But for environmental and ethical reasons I decided to make meat more of a side dish vs the center of the meal, and to mostly eat chicken vs more high environmental impact animal proteins like beef.

I think a lot of people that would never go full vegan can do well on this sort of less meat middle road.

Hot take: people get angry about veganism because they suspect, deep down, that vegans are right and feel guilty about eating meat. (Not taking the moral high ground here - I have put approximately zero effort into reducing meat intake at all.)

BirAdam

Hard disagree. People care about animals because they have faces that trigger their empathy. Plant life is still life. The destruction of plants to feed people is no more moral than the slaughter of an animal. The cutting of a redwood to make a desk is not moral. Many people also lack any kind of principle and make stuff up as they go. They get angry at killing a butterfly, but they don't care at all about killing a wasp. Likewise, people get upset about a pig, but they don't care about carrots. The carrots lack a face, and the wasp lacks pretty wings.

The carrot lacks a brain that can experience pain, fear and depression, that's why nobody cares about carrots.

The real problem with veganism is that you are a social outcast around normies. That was the biggest problem that I had. Also, veganism is essentially a "fundamentalist" way of thinking -- all or nothing. Now, I advocate for people to experiment with eating less meat and animal products, not zero. Even if people cut the amount of meat they ate by 20%, it would have a huge environmental impact. Also, the type of meat you eat also has a large environmental impact: Consider beef vs chicken.

So long as they're humanely harvested? Some argue that cows are mistreated when kept producing milk as much as they are, but I haven't looked into it because I'm selfish too.

Cows are mammals. They produce milk for their young for a period after giving birth then stop, just like a human woman. Which means that for us to take their milk we have to keep them constantly pregnant.

Ask a woman (or think about it if you are one) how they would like being forcefully impregnated then having their tits constantly milked, year after year. As a bonus, the born kids are separated into girls to be milked in the same cycle and boys to be killed and eaten.

Agree if the animals are treated well; but I have a very high bar for that. I would also accept eating animals which died of old age if it could be done safely. It's easier to just round this to "vegan."

RIP Magawa. Animals are wonderful. My grandmother had seizures for the latter part of her life and her doctors were unable to determine the root cause. A Great Dane mix her and my grandfather rescued was able to sense when one a fit was coming on and would lean on her until she was lying down and safe.

I recently visited the facility near Angor Wat Cambodia. Its a facility with a lot of promotional matetial and have greatbway of presentong themselves. I had a demo presentation with a rat doing demining so some observations: The rats are big. The idea is that they smell mines and are more useful than dogs since they are less than 5kg which detonates the mines. They are also better than human since they can smell old mines that are under soil or plants after so many decades. Unfortunate that is very labor intensive since there are two people escorting each rat and handle it with tethers.

For those reasons their effectiveness is limited.

A few km up the same road is the Cambodian Landmine Museum that has a couple of demo gardens where one can spectacularly fail find Lamdimes Found like 10 amd they were like one hundred, 2 right next to me…. Unfortunately that place which is run by a person called Aki Ra although having done a lot more work gets less financing.

Magawa cleared 1,517,711 sq.ft of land. He could work at a pace of 2,808 sq.ft (a doubles tennis court) every 20 minutes. If he maintained that pace, he worked 180.2 hours. Let's assume, with hazardous terrain, he worked 25% that speed on average. If that's the case he worked ~720 hours during a 5-6 year career. A different rat, Ronin, that found more stuff found a total of 124 explosive devices. So Magawa found no more than 1 explosive for every 5 hours and 45 minutes of searching. Or approximately one device every 17.25 tennis courts of searching.

Real needle in a haystack stuff, wow

For what it's worth, I'm not denying the benefit we obtain by testing on animals, nor am I suggesting that we live surrounded by rodents that we know to be vectors for multiple diseases that would affect us.

The comment above was merely an observation on the value of life and how little attention we pay to it.

We subject sentient beings to untold amounts of horror every day, and we are completely destroying the balance of life on earth with a system that is entirely devoted to serving humans--individual humans, not humanity.

The statue is not the point. The point is what this little creature did and how we might learn to show mercy and respect to our fellow sentient beings.

Sadly demand for such heros may increase in the future. Poland, Lithuania, Latvia, Estonia, Ukraine and Finland withdrew from the Ottawa Treaty banning personnel mines. And probably more countries will follow.

Whatever the reason, this will increase the likelihood of landmine casualties in the future. And not necessarily (only) in this area, but it weakens the treaty in general.

Part of these kinds of treaties is to accept some additional difficulty or expenses in defence for a more widespread benefit. I'm living in Finland and I would have accepted these.

jampekka

161 countries are still in the Ottawa Treaty, including all European countries except the ones who withdrew. I have hard time seeing how this treaty would have much effect on wartime alliances.

But if that's the case, what are "all the force multipliers"? Chemical weapons? Biological weapons? What share of the GDP for defence?

nickff

14 hours ago

It's nice that so many countries are signatories, but the countries which are currently involved in significant conflicts, have been, or are likely to be, are all non-signatories, have withdrawn, or are not abiding by their commitment. I'm not sure how much it matters that many non-warring countries are signatories to the convention, unless you think the Ottawa Treaty has actually prevented one or more conflicts (which I doubt).

I find some of the signatories laughable, as both sides in the Russia-Ukraine conflict have used them (with Ukraine being a signatory), while countries like Palestine and Eritrea have committed egregious human rights violations (since assenting), so I don't trust any commitment of theirs.

With respect to chemical and biological weapons, I think the reason they're not widely used is that they're relatively ineffective, and inconvenient, so I don't think they're a force-multiplier at all. Russia & Syria's (likely) uses of chemical weapons seem like more of a (mostly ineffective) desperate gamble than a brilliant move, though they demonstrate the non-existent consequences to such violations of treaty obligations.

Well, there is a bit of a problem. Ukraine has shown the reality of dealing with Russia and unfortunately landmines are back on the menu. Yes, it would be much better if we didn't need to defend from aggressors. But if you tie your own army one hand behind their backs then they will lose for sure. This about war, not Oxford boxing rules, and if one side commits one human rights violation after the other it would be great if you could keep the high ground but there are practical limits to that.

Note the incredible restraint of Ukrainians troops in dealing with Russian civilians and captured Russian military. But that does not translate into 'let's handicap our own forces'.

The warmongers are on the other side of the border. Europe is just reacting to this and the states that have rescinded the landmine ban are all directly in the line of fire.

I'm not trolling - its pretty evident that diplomacy was not effective and that the decision was made to go to war, whatever the cost - because thats what happened.

The diplomatic effort to save over a million men from needless massacre on the battlefield was not considered worthwhile by the ruling elites running Ukraine for the past two decades, in face of the immense profits to be made - by an elite few - in war profits.

In the interest of figuring out whether you profit from war or not, why don't you tell us the extent of your own investment in the military industrial complex which currently profits from propagating the "ma' Russia" trope ..

Yes, and I also believe that the Western mindset is stuck in a collective dialectic which disallows honest discussion on the subject, because in fact Europe has a lot to answer for on the topic of war, recently, and there is a lot of profit being made by those very European institutions responsible for collectivizing and propagating war-monger groupthink. Europe does not have altruistic arms dealers - it has war-mongering profiteers who have historical ties to the subject dating back hundreds of years.

Russia is not even the worlds #1 source of war-mongering, by a long shot. (The UK and the USA are, having murdered millions of innocent human beings since 2003 in multiple different theatres - countries and cultures deemed inferior by Western, fundamentalist, racist, ruling elites...)

I am not Russian, and can thus do nothing effective about Russia. I am a subject of the criminal 5-eyes western alliance which has murdered millions of innocent human beings since 2003, however, and I no longer believe in Western moral authority which gives us the imperative to 'do something about their war criminals' without "first taking care of our own war criminals", because we have far, far more heinously evil individuals still running the show with bloodied hands and with massive war crimes and crimes against humanity to answer for - yet we do nothing while bleating about Putin.

Wonder how hard it would be to train for diabetes? My under 10yo was just diagnosed with T1DM, a pocket rat sounds like fun and cheaper than a dog which is priced at unobtainium prices for us.

Animals are awesome, land mines are not. I hope we can avoid ever bringing that to our shores. Sadly, I know we now have air-mines (drones) so guess someone has to come up with drone sniffing pidgins or something (though obviously a parked drone probably doesn’t persist as long as a buried stationary mine and a flying drone less so).
