Preventing Human Elephant Conflict

Update (11/11/17)

It's been over 2 years since I first came into contact with human-elephant conflict in Zambia...and watching Netflix's The Ivory Game (Leonardo DiCaprio) last night just brought back me. And it's great to see the progress that's been made...with China announcing it will shut down its ivory market by the end of 2017.

It felt like yesterday when Sandy saved me from walking into a herd of elephants at night, and that was the start of my appreciation and love for elephants. While I grew up 3 blocks from the San Francisco zoo, it's something else when you see these gigantic mammals roaming in the wild. The last of the dinosaurs. 

And it really is sad to hear that there are only around 350,000 elephants left in Africa (compared with 10 million in 1900) with an annual decline of 27,000...which means that the extinction of the elephant may be possible during our lifetimes.

What many don't know is that human-elephant conflict in villages catalyzes poaching. As long as villagers continue growing up thinking elephants are the enemy, poaching is going to be accepted. There was a scene in the documentary where elephants were raiding a village (for food) at night, and the ravenous, weapon-wielding villagers gathered shouting:

"Today, this elephant, we will kill!"

Luckily, these animals were saved by the crew. The most viable solution right now is electric fences, but that is extremely costly. It will continue to be a long fight to come...but a much needed one. 

(May 2015)


In Africa, human populations are growing faster than elephant populations, leading to degradation of elephant habitats and increased conflict between elephants and small scale farmers. Elephants are being squeezed into smaller and smaller habitats, while farmers continue to plant crops that elephants like to eat. As a result, elephants have raided and destroyed 100% of the harvests for many subsistence farmers while contributing to increased violence between humans and elephants.


Why it matters?

Solving the issue between human elephant conflict can contribute to a resurgence of the African economy by increasing value in agricultural crop yields, while mitigating potential violent encounters between humans and elephants. And because elephants are vital to the ecological landscape, a solution can also yield environmental and wildlife benefits.



Sandy Simpson's electric fences have improved the lives of thousands of Zambians by eliminating conflict between humans and elephants.

When Sandy Simpson read a National Geographic article in the early 2000s that stated the animal population had been decimated by 90% in the past century, he packed his bags, sold his business in Europe, and moved back to his hometown in Kenya to work in animal conservation. 

For the last 2 years, he’s been working to solve the human elephant conflict in Zambia with his NGO, Green Rural African Development (GRAD). If you zoom into where rural African villages are located on Google Earth, you will find that many villages are located on or near the premises of a national park or in other words, humans and animals cohabit. This has resulted in years and years of conflict between humans and elephants, a problem that remains unresolved.

Zambian Wildlife Authority’s (ZAWA) response to this problem? Issue fireworks to local farmers to scare away the elephants. However, this created another set of problems – fireworks were dangerous and only a temporary fix. Thus, Mr. Simpson thought the best solution was prevention. His first project involved a local farmer, Robby, whose farm had been devastated by elephants for the past 10 years, leading to starvation and his family’s departure from farming in Livingstone, leaving him to solely end to the farm. Mr. Simpson started with simple string and reflective tape surrounding Robby’s farm, which provided instant results – elephants saw the reflective tape and string at night and immediately turned back. This is Robby’s story…

Robby’s Story

Robby’s family started a career in farming 30 years ago in Maloni Village, a community of 6,000 people within Livingstone. The first 10 years proved to be successful with limited conflict between humans and animals – the harvests were successful. Then, the elephants started coming. And for the next 20 years, they raided and destroyed the village crops every night. The maize. The okra. The tomatoes. Everything was gone even before the harvesting season began, forcing farmers to harvest long before crops were ripe for picking.

As a result, Robby’s family and most farmers in Maloni Village, never had a successful harvest in the past 20 years. And because most of these farmers are subsistence farmers, lack of crops also meant starvation at times. Zambian Wildlife Authority (ZAWA) could only do so much as to provide fireworks to scare off the elephants. However, according to Robby, fireworks never solved the problem and only scared off the elephants temporarily. In fact, fireworks were extremely dangerous. Robby’s brother attempt to scare off the elephants one night with fireworks was disastrous – the fireworks blew up in his hand and caused serious injury. In addition, elephants entering human settlement has also caused for serious danger stemming from human elephant conflict. While elephants are peaceful animals at heart, when taunted to an extent, they can become violent and have caused serious injuries and even human deaths.

 This forced Robby’s family to abandon the farming business 7 years ago to find greener pastures elsewhere, leaving Robby to independently take over the farm. He continued to struggle until 2014, when Green Rural African Development (GRAD) Founder, Sandy Simpson, decided the best solution was the prevention of human elephant encounters. Mr. Simpson decided to fence off Robby’s farm with string and lights, which produced immediate results as elephants saw the tape at night as a warning sign. While effective, there was still a big problem – villagers continued to steal the lights. Thus, Mr. Simpson decided it was most effective to install an electric fence system around Maloni Village to block out the elephants. The results were effective and incredible. Elephants would come at night but stop at the sight of the reflector tape and electric fence. So far in 2015, there have been no human elephant encounters in Maloni Village.

 With the elephants gone, Robby’s family decided to move back into the farm. And with newfound confidence, they decided to expand the farm to include a chicken house, pig house, and new varieties of crops. Previously, they had only focused on maize, acra, and tomato. However, they have now expanded to include eggplants, bananas, guavas, and sunflower to name a few. Robbie says the market demand is there but the supply is not, so they even have plans to acquire new farmland to meet the demand. In addition to feeding their family, they are now selling their crops in the village market and town, generating revenues of over $150 per month (vs. $0 same period last year). With newfound confidence now that their crops are safe from elephants, they have a target of $550 per month by year-end.


Why Is It Important?

Mr. Simpson’s work in human elephant conflict has directly and indirectly helped and benefitted thousands of people in Livingstone. Subsistence farmers are now not only able to feed and support their families but create a living off selling their crops, resulting in a boost to the local economy.  

Who else benefits? Large supermarkets no longer have to import vegetables and fruits from hundreds of miles away, potentially saving them thousands of dollars in transportation costs – they can now buy directly from the local farmers for a cheaper price in addition to fresher produce. Buying locally also mitigates the risk of potential losses or lag time from transportation. Locals and tourists also benefit – supermarkets may pass on the savings in lower produce costs and fresher produce. Finally, a reduction in human elephant conflict means less potential violence, which may lead to a revival of the elephant population stemming from a better relationship amongst humans and elephants.


What are the Challenges?

Mr. Simpson is currently a one-man team with the help of several volunteers. While human elephant conflict is a major problem in Africa, efforts to resolve the problem are minimal; Mr. Simpson is currently the only known person in Africa fully dedicated at resolving the problem.

“It’s a very simple solution, anyone can do this. But we need money and support.” 

Mr. Simpson has been currently funding the project with his personal savings, having spent over an estimated $250,000 in personal savings in the past several years. What are the costs? It takes an estimated $1,000 per kilometer of electric fence. Take into account the thousands of kilometers surrounding conflict farms, and you will get an amount surpassing the millions.


Final Thoughts

The problem between humans and elephants in Africa is clear and a big one. However, it is a big problem with a simple solution. While educating the public about the importance of ecological sustainability is a much bigger issue, a practical and implementable solution right now is prevention as there is no barrier separating elephants and farms. One risk is the possibility of snaring, but it is trivial in the overarching problem between humans and elephants. Furthermore, electric fence voltage is only high enough to shock the elephants from entering and is not lethal; elephants are also trained to steer away from fences.

Solutions in Africa have to be simple. Mr. Simpson has proved this to be true and has effectively improved the lives of thousands of people in Zambia. He has plans to develop additional preventative measures, such as buzzing infrasound devices on the fences (elephants hate bees). But he needs money and more importantly, support. This is a problem that affects thousands of farmers directly and millions of people indirectly. The perfect solution may not exist but the best solution at the moment is prevention.

What is school for?

What is school for in the modern day? It's a question posed by Seth Godin's TED Talk on education accompanied by his 139-minute Medium article as well as a topic of conversation from time to time over a late night glass of wine...

It's true. The American education system hasn't changed much in the past century, yet society as a whole has evolved immensely from the industrial revolution to the digital era we all know today. You know that infamous multiple choice test? It was actually invented during World War I as the easy and efficient way to keep the mass production of students moving forward - yet, it's still a big part of our school system today.

We were taught and trained to be obedient factory workers at the turn of the 20th century, and it that time. However, can the same rote memorization techniques have a place in the future of education? In a world dominated by machines?

That's a big question. But if I were to re-design my own education with what I know now about the "real world," these are some of the classes I'd think would be extremely beneficial:

Personal Finance

Time and time again, you hear about the pitiful American savings rate of 4%. I really don't understand the logic especially growing up in a traditional Chinese family that saves up to 50% on average. Living below your means is one thing and being aware of your actual spending is another. But many of us enter the real world with no real knowledge of how to handle money. Your gross salary does not equate what's deposited in your bank account. Yes, there are taxes other than sales tax. Did you know you actually lose money if you leave it in your checking account (with inflation)? Again, I'm all for experiences but not if I go broke acquiring them.

It's a fairy tale for us up until we graduate from college (for those who do), and then we hit the real world. Some times mommy and daddy won't be there. Oh crap, where did this interest payment from my "stable" federal student loans come from? Personal finance isn't rocket science. Some basic math and common sense (don't spend more than you have) can go a long way in the real world. It ought to be a mandatory education requirement.


Professional Skills

This will vary from profession to profession but most of us will agree that experience is King. Who knew mastering Microsoft Excel would lead to 70% of my success in both my consulting and finance jobs? But never did I take a Microsoft Excel class (nor was I informed) during my Business Economics program at UCLA. There are countless professional and technical skills that I wished I was taught before hitting the real world. For example, if I was hoping to start my career off in Public Accounting, it would've been invaluable to take a beginning to intermediate class in Microsoft Excel, PowerPoint, and Interviewing 101.


Communication and Presentation

Growing up, no one tells you that raising your hand in class would help you out in your career. The only times most of us did were when my grade depended on it. Nor did we do much team work. However, upon entering the real world, I soon realized communication was key. 

When I took a job with Universal Pictures in their Strategic Planning group, little did I know that I'd actually have to speak up in meetings and present to crowds of 50+. I was scared beyond belief of public speaking. It was that moment where I had to force myself to take a Toastmasters class (one of the best decisions I've ever made!) to learn how to communicate with confidence. I'm still working on that...but I believe it'd be beneficial for students to confront these fears in the classroom before the real world.


How to Write (Effectively)

Who knew the importance of a well-written email? "Good morning, take care, and thank you!" Not only in the business sense but the power of a well-written letter can spark wonders. Besides email, the power of the written word cannot be stressed enough. Empathy. Yes, learning how to write effectively teaches you empathy as well because you start placing yourself on the other end of the spectrum - what would that person think when he/she reads this?


Creativity and Innovation

In an age of automation and technology, educators and leaders alike believe creativity and innovation are some of the most important traits for future success. I remembered once upon a time being a sugar-addicted, can't-stop-won't-stop kid that doodled magic kingdoms and fire-breathing elephants in his middle school notebook. But I don't know what happened...I guess I grew up to structure. But schools like Stanford's are hoping to bring the kid back into the adult by restoring one's creative confidence.



Especially in an extremely divided world, empathy is a skill that can be taught...and it's better taught while young. The media has this power of distorting perspectives to the extreme. Traveling for me has been one of the most transformative forms of education in instilling a greater sense of empathy and curiosity of the world. It started with studying abroad in college, but it taught me how to be more empathetic and continue exploring. How do we instill a sense of empathy for future generations?


Teamwork and Leadership

The value of teamwork cannot be more instrumental in business and life success. I wish it was taught earlier in school through team projects instead of multiple choice exams. At the same time, many students form leadership skills through clubs, teams, and organizations that prove to be invaluable later in life. I think more emphasis on teamwork and leadership in classes would have been extremely helpful in preparation for the real world.



This would be a really cool elective. 80/20 rule? Pomodoro technique? Writing down the most important tasks in the morning? Use a password manager?

There are more than enough productivity hacks in the world and while some work and some don't, it's important to learn what works for you. Learning productivity hacks has saved me a lot of time and mental energy. Practical. 

If I had the chance to revisit college (or high school), these are some of the classes and skills I would've loved to learn. The world continues to evolve, and it's never been more important to learn how to deal with a future run by machines and human emotions. Just my 2 cents.
