Be wise about what you put online

21 03 2022

While you have little choice these days about posting your data and code online when you publish, here are some things to consider when contemplating putting potentially sensitive data online (modified excerpt from The Effective Scientist).

One aspect of making your data publicly available is the prickly issue of whether your data contain sensitive information.

Of course, there are many different types of ‘sensitive’ information that might accompany the more basic quantitative measurements of your datasets, with perhaps the most common being personal details of any human subjects. For example, if you are a medical researcher and your data are derived primarily from living human beings undergoing some procedure, trial, or intervention, then clearly you are bound by your human ethics approvals not to publish information like names, addresses, or anything that could be used to identify the subjects in your sample. In fact, human ethics approvals generally prohibit any sort of public accessibility to medical data that has personal information included; thus, the scientists concerned are being pulled in two different directions — keeping their subjects’ personal information out of the hands of the public, while still making the data available to other scientists.

There are ways around this, such as publishing only generic information online (i.e., by excluding personal identifiers) that could then be linked to the more sensitive data via unique identifiers. In these cases, any other researcher requiring the additional information would have to seek specific permission from the primary researchers, pending additional human-ethics approvals.

Neo-colonialist attitudes ignoring poachernomics will ensure more extinctions

14 01 2022

No matter most people’s best intentions, poaching of species in Sub-Saharan Africa for horn and ivory continues unabated. Despite decades of policies, restrictions, interventions, protections, and incentives, many species of elephant and rhino are still hurtling toward extinction primarily because of poaching.

Clearly, we’re doing something heinously wrong.

Collectively, we have to take a long, hard look in the conservation mirror and ask ourselves some difficult questions. Why haven’t we been able to put any real dent in the illegal trade of poached elephant ivory and rhino horn? How many millions (billions?) of dollars have we spent seemingly to little avail? Why haven’t trade bans and intensive security measures done the trick?

The reasons are many, but they boil down to two main culprits:

neo-colonialist sentiments driven by the best intentions of mainly overseas NGOs have inadvertently created the ideal conditions for the poaching economy — what we term poachernomics — to thrive by ensuring the continued restriction of legal supply of wildlife products; and
shutting off conservation areas to local people and directing the bulk of ecotourism profits away from source communities have maintained steady poaching incentives in the absence of other non-destructive livelihoods.

In our new paper — Dismantling the poachernomics of the illegal wildlife trade (led by Enrico Di Minin of the Universities of Helsinki and KwaZulu-Natal, and co-authored by Michael ‘t Sas-Rolfes of the University of Oxford, Jeanetta Selier of the South African National Biodiversity Institute, Maxi Louis of the Namibian Association of Community-Based Natural Resources Management Support Organizations, and me) — published quietly in late 2021, we describe how poachernomics works, and why our efforts to incapacitate it have been so ineffectual.

First, what is poachernomics?

Recreational hunting, conservation and livelihoods: no clear evidence trail

In some African countries, lion trophy hunting is legal. Riaan van den Berg

In sub-Saharan Africa, almost 1,400,000 km² of land spread across many countries — from Kenya to South Africa — is dedicated to “trophy” (recreational) hunting. This type of hunting can occur on communal, private, and state lands.

The hunters – mainly foreign “tourists” from North America and Europe – target a wide variety of species, including lions, leopards, antelopes, buffalo, elephants, zebras, hippopotamus and giraffes.

Debates centred on the role of recreational hunting in supporting nature conservation and local people’s livelihoods are among the most polarising in conservation today.

On one hand, people argue that recreational hunting generates funding that can support livelihoods and nature conservation. It’s estimated to generate US$200 million annually in sub-Saharan Africa, although others dispute the magnitude of this contribution.

On the other hand, hunting is heavily criticised on ethical and moral grounds and as a potential threat to some species.

Evidence for taking a particular side in the debate is still unfortunately thin. In our recently published research, we reviewed the large body of scientific literature on recreational hunting from around the world, which meant we read and analysed more than 1000 peer-reviewed papers.

Save a jaguar by eating less meat

8 10 2018

My encounter with Kaayana in Kaa-Iya National Park in the Bolivian Chaco. Her cub was around but cannot be seen in the photo

I was trapped. Or so I thought.

The jaguar came towards me on the dirt road, calmly but attentively in the dusky light, her nearly full grown cub behind her. Nervous and with only a torch as defence, I held the light high above my head as she approached, trying to look taller. But she was merely curious; and, after 20 minutes, they left. I walked home in the thickening darkness, amazed at having come so close to South America’s top predator. We later named this mother jaguar ‘Kaayana’, because she lives inside Kaa-Iya National Park in the Bolivian Chaco. My fascination with jaguars has only grown since then, but the chances of encountering this incredible animal in the wild have shrunk even since that night.

A few years after that encounter, I’m back to study jaguars in the same forest, only now at the scale of the whole South American Gran Chaco. Jaguars are the third largest cats in the world and the top predators across Latin America. This means that they are essential for keeping ecosystems healthy. However, they are disappearing rapidly in parts of their range.

Understanding how and where the jaguar’s main threats — habitat destruction and hunting — affect them is fundamental to set appropriate strategies to save them. These threats are not only damaging on their own, but they sometimes act simultaneously in an area, potentially having impacts that are larger than their simple sum. For instance, a new road doesn’t only promote deforestation, it also increases hunters’ ability to get into previously inaccessible forests. Similarly, when the forest is cut for cattle ranching, ranchers often kill jaguars for fears of stock loss.

Kaayana was seen years later by Daniel Alarcón, who took much better photos of her and her new cubs

However, the interactions between these threats are still not fully understood. In our new study, just published in the journal Diversity and Distributions, we developed a new framework to quantify how and where habitat destruction and hunting risk acted together over three decades, at the expense of highly suitable jaguar habitat in the Gran Chaco. We also analyzed how well the different Chaco countries — Bolivia, Paraguay and Argentina — and their protected areas maintained key jaguar habitat. Read the rest of this entry »

I acknowledge that I’ve been banging on a bit about southern Africa over the last few weeks, but I defend my enthusiasm on the grounds that my first trip to the Kruger National Park profoundly changed the way I view extinction theory and conservation biology.

Today’s post rounds off this mini-series with something I only alluded to in my last: interacting with tame elephants.

I have always been in two minds about the role of animals in captivity, with my opinion that most zoos edge toward the negative because most people who attend them appear to view the animals as a freak-show rather than appreciate their beauty or be fascinated by their behaviour and ecology; add the near-impossible-to-avoid psychological distress to which most captive animals succumb, many zoos in particular are probably better off not existing at all.

That being the case, I won’t simply write off all captive situations as ‘negative’, because if done well, they can have a wonderful educational role to play. Read the rest of this entry »

Transition from the Anthropocene to the Minicene

24 09 2016

I’ve just returned from a life-changing trip to South Africa, not just because it was my first time to the continent, but also because it has redefined my perspective on the megafauna extinctions of the late Quaternary. I was there primarily to attend the University of Pretoria’s Mammal Research Institute 50^thAnniversary Celebration conference.

As I reported in my last post, the poaching rates in one of the larger, best-funded national parks in southern Africa (the Kruger) are inconceivably high, such that for at least the two species of rhino there (black and white), their future persistence probability is dwindling with each passing week. African elephants are probably not far behind.

As one who has studied the megafauna extinctions in the Holarctic, Australia and South America over the last 50,000 years, the trip to Kruger was like stepping back into the Pleistocene. I’ve always dreamed of walking up to a grazing herd of mammoths, woolly rhinos or Diprotodon, but of course, that’s impossible. What is entirely possible though is driving up to a herd of 6-tonne elephants and watching them behave naturally. In the Kruger anyway, you become almost blasé about seeing yet another group of these impressive beasts as you try to get that rare glimpse of a leopard, wild dogs or sable antelope (missed the two former, but saw the latter).

Staggering rhino poaching in the Kruger

14 09 2016

I have the immense honour and pleasure of attending the University of Pretoria’s Mammal Research Institute 50^th Anniversary Celebration conference currently being held in the Kruger National Park. To be rubbing shoulders with some of the greats of African ecology is humbling to say the least, but it’s also a huge opportunity to learn about the wonderful wildlife Africa still has.

Stepping back into what the Pleistocene must have been like in Australia, Europe, and North and South America, I’m moved to near tears by the truly awesome¹ megafauna that still exists here. This is my first time to Africa, and I cannot begin to capture how I feel by seeing these amazing species in the flesh.

But as you probably already know, this last megafauna is under huge threat, and we seriously risk repeating the extinctions of the other continents within less than a century. While the topics associated with the threats are diverse, complex and challenging, one talk here stood out for me among all others: that by Ken Maggs of SANParks.

Kruger holds about 70% of the white (Ceratotherium simum) and black (Diceros bicornis) rhino in South Africa, and about 30% all rhino in the world (98.8% of all white rhino are found in just four countries: South Africa, Namibia, Zimbabwe and Kenya).

So for the ~ 10,000 rhino in Kruger, the following numbers should shock you; Ken showed a slide with the following information: Read the rest of this entry »
