Backpacking: Eco-tourism or Overtourism?


Backpacking: Eco-tourism or Overtourism?

               When one thinks of a backpacker, there is a certain stereotype that comes to mind: a western millennial who is uber eco-conscious (this generation’s hippies). They’ve got their backpacks, GoPros, a limited budget, and a zest for authentic experiences around the globe. They make a concerted effort to distinguish themselves from their counterparts, the baby boomers, who they perceive as jumping from seaport to seaport enjoying the luxurious side of travel without concern for the potential deleterious effects of their journey. Some might say that baby boomers are pumping thousands of dollars into local economies: shopping, taking tours, and handing out generous tips, whilst the backpackers only spend money on cheap eats, beer, and buses. As someone who has traveled the world pretty extensively as a backpacker, I think there is a much more complicated picture to be painted.  


         
                I started my travels at 23 years old, keen to see all the sites I watched on the History Channel as a kid and studied in my Classics undergraduate degree. My first trip was the typical Eurail-pass tour ticking off every major European city. As I was on a limited budget and traveling alone, I woke up early every morning and walked the city, refusing to take tours or even public transportation, ate as cheaply as possible, and debated which museums, castles, and attractions were worth the hefty price tag. In the end, those were few and far between. When I would return to the hostel in the evening, I’d find the other backpackers lounging around, waiting for the party to start, rarely actually experiencing the city. After a day or two, I’d hop on the next train, feeling I’d “seen” the city, totally exasperated by my fellow youths wasting away their travel time.


The obligatory Eiffel Tower picture
               Fast forward eight years to a trip in Southeast Asia that solidified my stereotype of backpackers, and this time I can’t absolve myself from traveling irresponsibly like my peers. SE Asia means Full, Half, and Black Moon parties, all used as ploys to boost tourism and they are accompanied by a plethora of plastic waste. Plastic is integral to the tourist culture of consumption: alcohol is provided in red Solo cups (or buckets), straws abound, and Pad Thai comes packaged in disposable containers with plastic cutlery (not to mention the bottles of water used to re-hydrate the next day). The consequences are real: Thailand’s Maya beach, made famous in the movie The Beach, was closed to the public shortly after my visit and will remain so until 2021, due to environmental degradation. Are backpackers worse than other travelers, racking up atrocious carbon footprints and causing externalities without contributing economically to the countries they visit?


Drinking a bucket in Thailand with 3 straws (the horror)!
               According to the data, counter to some perceptions, young travelers do spend money. In 2012, the World Youth Student and Educational (WYSE) Travel Confederation released a report that showed young travelers account for 20 percent of international tourists, spending “$217 billion of  the $1.088 trillion tourism "spend" worldwide … an increase that vastly outstripped that of other international travelers . . . making the group an important economic force.” The statistics are based on a survey taken by more than 7,600 young travelers (18 to 30) from more than 100 countries (Mohn, 2014).  These numbers are currently listed as 23% and $308 billion on the WYSE Facts and Stats webpage.  Backpackers may be on a budget, but they have what most others do not: time. That budget of $50 a day may seem paltry to vacation-goers who are used to spending a few grand on their week holiday, but when you look at the length of the trip, it adds up.  Fifty dollars a day for six months comes to $9,000, and trips of this length are not uncommon. The WYSE report showed that young travelers trips are lengthening, stating that “the number of trips more than 60 days has increased over the last five years (Mohn, 2014).”   During my travels, I have met countless backpackers, (including many Australians where minimum wage is $23 an hour) who have saved $10-20k for their prolonged (up to two-year!) trips around the world. It requires working hard and saving, while making personal sacrifices for a significant period of time. One must be able to push aside fears of missing out on a few years of climbing the corporate ladder or saving for a down payment for a home or retirement.
               As far as whether backpackers are destructive partiers drinking everything in their path, or vegan hippies practicing yoga and following the Leave No Trace principles whilst they “find themselves,” Eat-Pray-Love-style, the jury is out. A friend of mine, Derya Uysal, said “for me, backpacking was always about saving money and I don’t think I ever really thought about the environmental factors/sustainability.” She also noted that “I don’t know if backpackers have become more environmentally conscious, but I’d say that people of a certain age [millennials] (myself included) have generally become more conscious of the impact they have.”  A survey conducted in 2008 examined the behavior of backpacker tourists in relation to the environment and determined that “backpackers do not exhibit particularly ethical tourist behaviour as propounded by the ethical tourism models. A small proportion of respondents did come close to model ethical behaviour, whereas another small group appears to exist at the other end of the scale.  In between there is a range of other backpacker groups that one extent or another reflect some model ethical behaviours. A significant proportion of respondents to the survey indicated that they would change their behaviour if tourism providers were more responsible.” This is similar to my friend Sheri Arab observations, “from what I have seen, I think it is a mix. You get some backpackers that are doing the sustainable and/or eco-tourism thing, and then you get some that are just destroying local communities and environments for a cheap year of partying.”  The study found that backpackers are generally more interested in personal experiences and development. Nonetheless, volunteering with local communities and participating in environmental causes and studies did rank third and fourth respectively as motives for the survey’s respondents (Murphy, 2010).
               I, for one, have changed my traveling ways. I’ve learned city-hopping is not the best way to travel and have since slowed down drastically, taking a minimum of two weeks per destination, ideally 3-4 weeks. I’ve increased my budget to enjoy the tours and see the sites, choosing top-rated hostels (with the occasional private room!), upgrading to what some call a ‘flashpacker’ or ‘glampacker.’ I now travel with a bamboo cutlery set, a Lifestraw water bottle for when tap water isn’t potable, a double-insulated aluminum bottle for when it is, and various forms of reusable bags and containers so I don’t have to use single-use plastics. My friend, Kathleen Parsons (who puts even my travel record to shame), said she thinks that “backpackers often travel much more environmentally than others - because they are looking for cheaper ways to get around and to travel on a budget.” She has noticed that they tend to fly a lot less, taking trains or buses for those longer distances that a typical traveler would fly, and are less likely to book private tours or rent a car. She too started carrying a LifeStraw filter, and on a recent trip to Nepal said, “we were definitely the only people on the trail doing this. The guides and porters were in awe because they clearly hadn't seen it before either.” I also look for sustainable accommodations such as El Zopilote Permaculture Farm and Hostel, in Ometepe, Nicaragua. I participate in activities such as a workshop with De La Gente where we got to make bags out of recycled huilpil (traditional Guatemalan handmade shirts) with a local woman in her home in a nearby town (outside the main city).

               While the negative impacts of backpacker tourism are evident, there are positive impacts too, albeit a bit more subtle. My friend, Roseanne West, who I met in SE Asia, questioned her input to the destinations she visited and their local economies, saying “having [had] limited time and money, I also traveled quickly and did not contribute to the places that I went to. Or did I?! Because actually by visiting certain places you are contributing to the economy - [through] tourism.” She understands that events such as the Full Moon Party might be less than beneficial, but she also stayed in various local villages, “where we learnt a lot from each other’s cultures and beliefs, so again contributing? Of course. All visitors were respectful, willing and thankful.” Traveling may have adverse effects on the environment, from contributing to greenhouse gases, increased resource use (such as water bottles and take out containers), and contributing to the trampling of sensitive ecosystems that we trek to see. However, tourism also leads to opening one’s eyes to the world, which in turn creates stronger connections across cultures. People are more likely to choose to conserve and protect what they have seen and with which they can identify. Just as viewing a panda in a zoo may lead someone to “adopt” a panda through the WWF, traveling sometimes leads to the protection of cultures, historic sites, and nature, through the fees travelers pay visiting them.  Backpackers are often young minds setting off to explore the world, and they may just come back totally changed and ready to save it. As Mark Twain famously put it, “travel is fatal to prejudice, bigotry, and narrow-mindedness, and many of our people need it sorely on these accounts. Broad, wholesome, charitable views of men and things cannot be acquired by vegetating in one little corner of the earth all one's lifetime.”

Preserving the Incredible Shrinking Island: LiDAR, SfM, & GIS on Egmont Key, Fl

In May of 2019 I participated in a project on Egmont Key, in conjunction with USF (Patel College of Global Sustainability and Access 3D Lab), the Egmont Key Alliance and the Seminole Tribal Historic Preservation Office (THPO). Egmont Key, which has been dubbed "the Incredible Shrinking Island," has lost half of its land mass over the last 100 years. The power plant which was originally built in the middle of the island in 1919, is now a popular snorkeling destination.



This project aims to digitally capture remaining historical structures on the island, before total submersion, allowing future generations to explore this small but historically significant island. Also this project hopes to shed light on the lesser known Seminole internment that occurred here due to the Indian Removal Act of 1830. Egmont Key was used as a holding area for Native Americans taken from south Florida to Oklahoma in 1858-9. 


Dr. Brooke Hansen and Dr. Laura Harrison envisioned this project and brought it to fruition and to them we are all very thankful. 
Me and Brooke
We started this project learning how to use terrestrial LiDAR scanners. Terrestrial laser scanning (TLS) or Terrestrial LiDAR (light detection and ranging) collects 3D coordinates by firing laser pulses at a target and measuring the return distance to the scanner. TSL scanners can capture up to a million points per seconds with millimeter accuracy. The points create a photo-realistic point cloud dataset which can be converted into a DEM (digital elevation model). DEMs can be used for topographic mapping and spatial analyses. Practical uses include creating high-resolution survey grade maps of sites and 3D mapping.  

Dr. Laura Harrison from USF’s Access 3D Lab was our project coordinator. We used the FARO Focuss 150, which has a 150m range.




Our initial scan site was the Battery Charles Mellon (1898). The Mellon Battery was built during the Endicot Perdiod as part of Harbor Defense of Tampa Bay. The battery was decommissioned during the 1920 disarmament program.


In addition to LiDAR, we also collected data using Structure from Motion (SfM). SfM is a photogrammetric range imaging technique that takes 2D images and creates 3D models. Photogrammetry is the science of making measurements from photographs. There is both Aerial, in which cameras are on aircrafts, UAVs (unmanned aerial vehicles) or drones, and Terrestrial and Close-range, with the camera being on the ground, hand held, or mounted on a tripod or pole. We worked with Dr. Mel Rogers and her PHANTOM RTK drone to collect photos of the helipad, cemetery and lighthouse.

After collecting all of our data we went to the Access 3D lab to process it. We worked with Steven Fernandez for three days. We took LAS data from NOAA Data Access Viewer and coupled it with our own data to analyze the islands changes from 2007, 2013, 2015 to present. We made Polygons and DEMs of the island, looked at the canopy coverage, and measured the volume of sand. According to the data, the island went from 288 acres in 2007, to 279 in 2013, back to 288 in 2015. We could see that the increased acreage was mainly on the SE tip, likely due to beach re-nourishment being done by the USACE (United States Army Corps of Engineers). The tree canopy was 143.8 acres in 2015, about 50% of the island. The volume of the island has changed from 40,500,000 in 2013 to 44,000,000 in 2015. So the island is technically NOT shrinking!

Richard Sanchez, the President of the Egmont Key Alliance was actively involved in our project. He gave us a personal tour and contributed a variety of historical knowledge about the island. We explored the island's "ghost town," which consists mostly of surprisingly intact brick roads with some not so solid foundations, where there was once tennis courts, a hospital, a post office and many other city dwellings, including the morgue. Fort Dade was built during the Spanish American War of 1898, however by the time the structures were built three years later, the short-lived war was long over. 





We were lucky to have Dave Scheidecker, a representative of the Seminole Tribal Historic Preservation Office, involved in the project. He came out a few times to Egmont Key, and gave us invaluable information about the history, specifically nineteenth century Seminole history on Egmont key. Here are some presentations he gave:



Some highlights from his presentation:
  • Clara Barton was a Red Cross nurse on the island when soldiers were quarantined due to yellow fever during the Spanish American War.       
  • Robert E. Lee suggested preserving Egmont Key for military purposes while he was there, however he was only a junior officer at the time.
  • Egmont Key is an archaeological preservation worst case scenario: erosion, humidity, fires, inundation from water, and development of Fort Dade during a time with no historical preservation laws whatsoever; therefore they must rely on oral history and archives.      
  • Analyzing human remains is strictly taboo for the Seminoles as they don’t touch dead bodies (even dead animals other than for food). When burials are found, all work stops.
  • Egmont Key was decommissioned by the military in 1923, the Coast Guard was there until 1974, and Egmont Alliance came out in 1989. It is unclear what happened in between.
  • The Cemetery was dug up in 1909-1912 and the soldiers and 5 or 6 unknown Indians were sent to St. Augustine National Cemetery, where there are many other burials from the “Indian Wars.” Civilians were given to their families wherever possible.      
  • The helipad is the assumed location of the Indian depot because it is naturally open and flat, as well as located near the lighthouse and the former docks. The blockhouse style was two levels with wooden palisade walls, and was the standard defense building against Indians.      
  • Polly Parker was a tribal member who was captured on the last ship on the way to Oklahoma. They stopped at St. Marks and she convinced the guards to let them out to collect medicine, where half of them escaped. They walked back from Tallahassee to Okeechobee. She was very sick, however survived to over 100 years old. She went on to mother several more children in her late thirties and beyond (last known daughter birthed at 51), with approximately 20% of the Brighton reservation of Seminole being descendant from her.
  • The Egmont Key Indian depot was built and used in 1857 and left in 1858. It was not standard military procedure to burn down at that time. Soldiers from the Civil War would have appeared as early as 1861, followed by soldiers from WWI. It is unclear/unknown what exactly happened to the remains, and since they were wooden, any evidence is likely lost.      

The Tampa Bay Times came out and wrote an article about our project:

They can’t turn back waves, but USF and Seminoles are preserving Egmont Key in digital form.

May 6th, Day 1: Intro to Scanning with Dr. Laura Harrison

Dr. Harrison's Scan Plan for Day 1

Today we learned about sphere placement:
  • Minimum 2 spheres, ideally 3-5
  • Scan 3 permanent every day
  • Don't place in a line
  • Make sure the scanner isn't splitting a sphere
We positioned our three  permanent spheres that will be used for the duration of the scan at this site. We must scan the 3 permanent spheres every day for “geo-referencing,” which is possible without spheres, but much more difficult. Vegetation/metallic/shiny/black/highly textured surfaces are more difficult to scan. We must scan directly under doorways. We discussed our preliminary scan plan with advice from Laura. We started the scan and exited the scan area, to minimize the disruptions in the scan cloud/photos. We learned how to set up the scanner:

Important Scanner Settings:
Project Setup:
Manage -> Projects -> Default Project -> “+”
Project Name: Egmont_Chorizo
File Base Name: Egmont_Chorizo_0506_CM_
        o   Notice the file base name has an underscore after the word!
Initial Scan No: 1 (from 0)
Profile Setup:
        Manage -> Profiles -> Outdoor greater than 20m “20m…”
        Parameters -> Resolutions -> ¼ Resolution, 4X Quality
        Parameters -> Color Settings -> Exposure Metering: Even Weighted
        Scan Duration: 10:16
        Manage -> Sensors -> Inclinometer: Make sure the Inclinometer is centered in the blue. 

Me, Tyler DeMonde, Trinity Miller, Kiana Sladicki, and Chorizo (Scanner)

May 7th, Day 2: Tour with Richard Sanchez
Today we developed our own scan plan. Scan 7 was deleted due to interference in the field. We went on a tour of the island with Richard Sanchez from the Egmont Alliance. 
Some scanning notes:
Inclinometer is difficult on the sand, kept sinking -> yellow
We had a dead battery at the start
The 10:16 scan time is NOT accurate, closer to 12:30 (perhaps the 2 extra minutes is for the photos?)
Some notes about Egmont key/the project:
It is a popular tourist destination with many tourists walking through (will be in scans)
Our scanner is about 50ft from the water, with 6” of SLR, the fort will be underwater
People are taking bags of shells from beach, in fact the ferry was selling shell bags and encouraging visitors to take as many as they can carry, despite there being signs forbidding removal of any artifacts
Ferry also chases dolphins and other wildlife, which goes against Sustainable Tourism best practices

Taking a break from the sun!


May 8th, Day 3: Drone Day with Dr. Mel Rogers
We continued scanning the Mellon battery. Environmental challenge: love bugs! Scan 3 was deleted because of scanner error ("scan incomplete").
Today, Kiana and I worked with Dr. Mel Brooks and her drone to collect photogrammetry data from the helipad. 
Kiana Sladicki, Dr. Mel Rogers and me on the helipad, the supposed site of the Indian depot

May 9th, Day 4: Tour from Dave Scheidecker
Today Dave Scheidecker, a representative of the Seminole Tribal Historic Preservation Office, came out with us and gave us a great history of the island. 

May 10th, Day 5: Finishing Mellon Battery 
Today we learned about stitching everything together as we moved from one side of the battery to the opposite to get the outside wall. We finished early because of the scan plan.



May 13th & 14th Day 6 & 7: In the Lab with Laura and Michelle Assaad
Today we were in the Access 3D lab. We used FARO Scene to look at the scan data from day one. We learned how to clean up the data by removing unwanted objects such as people, tripods, scanners, cases, and spheres. 

Tyler DeMonde's video

Faro Scene 7.0 Workflow
1. Transfer your ALL data from SD cards to your desktop
a. Don’t just import the scans. You need to keep the Backup, Preview, Projects, and Scans together. The data is all connected. If you separate them at this beginning stage you will have issues later on.
b. Organization is key! Divide data by day and then by scanner.
c. Example:
12-17-2018
            Chorizo
            Manchego
            Diego
12-18-2018
            Chorizo
            Manchego
            Diego
2. When in Scene click CREATE PROJECT and name your project. Pick your save location.
a. Easiest to keep a designated save location for all your Scene projects.
3. Go to the IMPORT tab and drag in scan data.
a. In this stage, you just need the scan data.
b. When it has imported you need to press OK, otherwise it will not let you import anything further.
4. Once you have imported all your scans save your project in the save tab.
a. Add what step you’re on in the comments section just in case you have to revert back.
5. Go to the PROCESSING tab and press process, on the upper right-hand corner of the screen.
a. Check:
                                                    i. Dark Scan Point Filter
                                                  ii. Stray Point Filter
                                                 iii. Find Spheres
b. Start processing
6. Once processed save and then subdivide by day and scanners (will make your life so much easier).
7. Go to the REGISTRATION tab. Pick a section from a day and press AUTOMATIC registration first by targets.
a. If it fails to register automatically by targets then try automatic registration by top down view and cloud to cloud.
b. If this doesn’t work go into MANUAL registration and manually pick spheres or points in planar view.
                                                    i. Be sure to save often and write comments. You will inevitably have to revert to a previous       save and it helps to have your notes.
8. Go to the EXPLORE tab and create a Project Point Cloud (PPC).
a. Check:
                                                    i. Eliminate duplicate scan points
                                                  ii. Homogenize point density
                                                 iii. Apply color balancing
9. Clean scan data by using the clipping box and lasso selection.
a. Save frequently and update the PPC every hour at least.


May 15th, 16th & 17th, Day 8-10: The Lighthouse 
Next up to scan was the lighthouse. We started with all three scanners doing a loop around the lighthouse, with both an inner and outer track. Then as the other two scanners moved around the other buildings, Chorizo went inside the lighthouse. Due to the symmetry of the lighthouse, I suggested we add a letter suffix to each File base name to make stitching it together easier in the lab (i.e. Egmont_Chorizo_20190516_CM_A_).  We were able to open the windows of the lighthouse, which allowed us to capture outside spheres in the bottom scans. Things got a little tight in the lighthouse, so Kiana and I tackled most of the inside on our own. We found it best to use the spheres with the stronger magnets, since most of our sphere placements tended to be on the stairwell/other metal structures. We were able to leave spheres inside over night, to serve as permanents so we could get going quickly everyday. 





May 20th, 21st, & 22nd, Day 11-13: In the Lab with Steven Fernandez
We went back to the Access 3D lab, this time to work with Steve Fernandez. For me, this was the most challenging aspect of the project, as I am basically computer illiterate! There were a few hiccups, mainly the computers malfunctioning, but we were able to complete several projects from previous data on the island (NOAA), and our point clouds from the scanners and drones. 
Jon Rodriguez' DEM
May 23rd & 24th, Day 14 & 15: Lighthouse, Cemetery and BBQ
Returning to the lighthouse after 5 days, we entered into a bit of a disaster. Two of the four spheres we left in place had fallen (magnets attached to the stairwell). We still had two left to stitch together and during our scanner setup, one of them was knocked over, leaving us with only one! Luckily we were in a window portion of the lighthouse, with multiple geometric points allowing for manual stitching in the lab. After we finished up the lighthouse, we joined the other two scanners in the cemetery. We did a loop around the cemetery as the others did inside. Note: we did not want to put any stakes into the cemetery for permanent spheres, out of respect for the dead. 
We wrapped up our scanning for the project and enjoyed a great BBQ. We were awarded our Gold Badges for the project.
