In our episode on Urban Farming, we sit down with local farmer Fai Hui of Wild Roots Organic Farm and co-founder of Gogreenhongkong.com to learn about the value of soil and organic farming. He also shares about some of the challenges facing farmers in Hong Kong -- yes, there’s farmers in Hong Kong! Fai explains what soil is and why it’s so special. It turns out that soil is a highly undervalued resource, and we’re using it up faster than it can be replaced, just like we’re doing with fossil fuels. We also discuss what “organic farming” really means and why it’s, in many ways, a better method for growing food. Fai also tells us how pesticides and herbicides, which you often find in conventional farms, are damaging to our environment and health.

In Hong Kong, very little of our vegetables and fruits are produced locally (around 2%), but there are some concerns about this low number. For example, Fai raised a very important point that Hong Kong has banned certain pesticides and herbicides, but these are still allowed in China. So, food grown with these banned substances can still be imported and sold in Hong Kong! In the show, we discuss the government’s plans to develop an “agripark” to help revitalize farming in Hong Kong, and Fai raises several concerns about the plans. But it is still encouraging, as Fai points out, that if we use our resources wisely we could potentially grow about 20% of our produce locally in Hong Kong. 

A theme throughout the show is that we need to realign our priorities regarding food. Better farming practices involve more work, and thereby food grown sustainably costs more, but it’s an investment well worth making. Later in the series, we’ll continue to discuss about sustainable food choices and what “organic” labelling means.


How You Can Get Involved

Eat Seasonally
Fai talked eating seasonally is good for the environment, which means eating vegetables during the time of the year they grow. Some examples in Hong Kong are:
Winter Vegetables
lettuce, broccoli, carrots, spinach, tomatoes, squash plants (zucchini), kale
Summer Vegetables
cucumbers, okra (ladyfingers), eggplant (aubergine), long beans, Chinese leafy greens (water spinach, morning glory or ong choi), bitter melon


Gardening Yourself

There are actually many opportunities to get involved with gardening yourself in Hong Kong! Here is a list of some gardens you can visit or join to grow your own vegetables:

Buy Local Vegetables
At markets:
Local food delivery:

Clear Days on the Horizon (Ep.2)

Initial broadcast - 8:00 pm Friday July 24, 2015

Update: Please read the Ming Pao news article about our air pollution episode.

Each of us takes over 20,000 breaths a day. This episode looks at what we're taking into our bodies in Hong Kong. Dr. Misha Schurman-Boehm, an atmospheric chemist at the Hong Kong University of Science and Technology, talks with us about what's in our air, where it comes from, and where it goes. We have severe air pollution problems in Hong Kong, but that doesn't mean that we can't have clear days on the horizon.

If you want to know the relative quality of Hong Kong's air, you can check our current and past-two-day average pollution levels. At that site you can also access data from some individual Hong Kong monitoring stations to see the air quality near your home. Interestingly, Misha noted that if you are at street level, the actual amount of pollution you can be breathing in ("roadside pollution") can be 10x the amount that's being recorded at monitoring stations. If you want to find data from all individual stations visit the EPD network. However, Misha mentioned that shipping is a big cause of air pollution, but there aren't stations near the areas of heavy ship traffic in Hong Kong!

When you look at Hong Kong's air data, it's hard to believe that World Health Organization (WHO) air pollution guidelines recommend that daily mean PM2.5 values not exceed 25.  Misha said that most days out of the year break that standard, and she mentions how it's actually not even a very high standard. WHO guidelines and a wealth of other air quality information are here.  


How to get out? 

Misha noted how it can be very meaningful to get out and experience nature and the outdoors. We couldn't agree more, considering how spectacular Hong Kong's outdoors are. So, if it's a clear day and you want to get out into the air to enjoy nature, there are a number of organizations that can help you do that through walking, hiking, trail running, mountain biking, kayaking, all the way up to rock climbing and beyond!  

The WWF has a centre at the Mai Po wetlands in the New Territories, and they offer a varity of tours depending on the season (Price around $120/person). The Hong Kong Tourism Board organizes nature tours as well in areas all around Hong Kong (Price $300-$800 depending on tour; many of these tours are organized by Walk Hong Kong). To save money, you can just join many of the free events through various outdoor organizations on Meetup.com. For example, the Hong Kong Hiking Meetup have organized hikes every day for all levels (sometimes even multiple ones!), or the Microadventures Hong Kong group goes out cycling and exploring. There's also several organizations which put together all kinds of outdoor activities for youth in Hong Kong, including Asia Pacific Adventure and Outdoor Education Asia.


In Ep. 8 "Hiking Hong Kong" we'll sit down with hiking organizers and learn much more about outdoor activities and Hong Kong's country parks! Please stay tuned. :)

Sea of Life (Ep. 1)

Initial broadcast - 8:00 pm Friday July 17, 2015

To listen to the show, please visit the RTHK archive here.

This show is about the wonderful marine life living under Hong Kong's busy waters. We sit down with HKU marine biologist, Dave Baker, to learn more about Hong Kong's corals and marine life. He shares some interesting facts about the coral life and discusses some of the major challenges facing waters near urbanized areas (namely, eutrophication or the abundance of nutrients in the waters).

Update: Please see a Chinese-language summary about this episode on Ming Pao here

Getting Out on the Water

Interested in experiencing Hong Kong's amazing waters? Here's what we can recommend:

Kayaking with Meetup group Hong Kong Sea Kayakers & Friends or you can explore water sports activities with the Leisure and Culture Services Department (kayaking, sailing, windsurfing).
To kayak with the Meetup group you have to participate in two days of training (Part A and Part B training), but it's well worth it. You can then join on their day trips in various locations around Hong Kong: Tai O, Sai Kung, Cheung Chau. They're a very friendly and welcoming group with good equipment.

The LCSD's Water Sports Centers offer very cheap training courses (can't beat $30!), although it can be a little tricky to get a place in them in the summer. Keep trying, and in the winter, it's much easier to get a space! They've got nice facilities with lockers, hot showers, and will even loan you wet suits when it's cooler. Once you get your training (~3 days of training courses), you can join their tours, like their mangrove tour or corals tour. The LCSD's The Jockey Club Wong Shek Water Sports Centre in Sai Kung is right next to some beautiful corals! Please feel free to ask us if you'd like more information about these organizations!

Also, the WWF Hong Kong also has an education centre in Hoi Ha, one of the best places for viewing corals in Hong Kong!
