International Day of Forests Introduction

Roger 0:02

Talking Trees with Lillian Jad . Welcome to Talking Trees . Today we spotlight the International Day of Forests , a UN-declared celebration promoting forest awareness . We'll also explore Singapore's City Biodiversity Index , a comprehensive tool featuring 28 indicators designed to help cities assess and enhance urban biodiversity , ecosystem services and green infrastructure . Let's dive in .

Jad 0:34

Happy International Day of Forests to all you arborists out there .

Lilly 0:38

Oh yeah .

Jad 0:39

It's a day the UN set aside to really appreciate just how vital forests are to our world .

Lilly 0:46

Absolutely .

Jad 0:47

Now I think for you guys , as arborists , this day has a special kind of resonance , given all the work you do managing and protecting these incredible ecosystems .

Lilly 0:58

You're absolutely right . It's a great opportunity to take a step back and think about the big picture of what we do .

Jad 1:03

Yeah .

Lilly 1:03

But today we're going to go beyond traditional forestry .

Roger 1:06

Okay .

Lilly 1:07

Into the really fascinating world of urban environments .

Jad 1:11

Yes , we're diving into something called the Singapore Index . It might not be something that comes up every day in your work , but trust me , it's got a lot to offer in terms of understanding and improving biodiversity , even in a bustling city .

Lilly 1:23

Exactly . You know , it's easy to think of deforestation as something happening far away in rainforests .

Jad 1:29

Yeah .

Lilly 1:29

But the reality is we're losing a crazy amount of forest every year .

Jad 1:33

Yeah .

Lilly 1:34

Over 13 million hectares . To put that in perspective , wow , that's roughly the size of England .

Jad 1:40

Oh wow , Vanishing every year . That's a sobering thought , and I bet most people don't realize that deforestation contributes almost as much to global carbon emissions as the entire transportation sector does , somewhere between 12 and 18 percent .

Lilly 1:56

It's a real reminder of how interconnected our planet is , and it highlights how important trees are , not just in remote forests , but right here in our cities too . Right , and that's where you , as urban arborists , come in . Yeah , your work planting and maintaining trees , yeah , directly helps reduce those emissions .

Jad 2:15

So how does the Singapore Index fit into all of this ?

Lilly 2:17

So the Singapore Index is a self-assessment tool for cities .

Jad 2:21

Okay .

Lilly 2:21

To measure how they're doing in terms of biodiversity conservation . Okay tool for cities to measure how they're doing in terms of biodiversity conservation . Think of it as a benchmark to see how well a city is doing in terms of protecting and enhancing its natural assets .

Jad 2:30

I'm starting to see the connection here .

Lilly 2:32

Right .

Jad 2:32

But how does it actually work ? Is it just about counting the number of trees in a city ?

Lilly 2:37

It goes way beyond that . Okay , it takes a holistic approach .

Jad 2:40

Okay .

Lilly 2:40

Looking at three main components Right Native biodiversity in the city , the ecosystem services provided by that biodiversity , and how the city is governing and managing all of this .

Jad 2:52

Okay , let's unpack this a bit , starting with native biodiversity in the city . Sure , what exactly does that entail ? Is it just about having parks and green spaces ?

Lilly 3:01

It's more nuanced than that . It looks at things like the proportion of natural areas within the city , how well those areas are connected and the presence of native species , especially within built-up areas where you often work .

Jad 3:15

So it's not just about having little pockets of nature here and there . It's about making sure they're part of a larger functioning ecosystem

Global Deforestation: The Sobering Reality

Jad 3:22

. You got it .

Lilly 3:23

One really interesting indicator in this component actually focuses on the number of native bird species found in built-up areas .

Jad 3:31

Oh , interesting .

Lilly 3:32

It's a clever way to see how well a city is really integrating biodiversity into its fabric , rather than just relegating it to parks and reserves .

Jad 3:40

As an arborist , I can already see how my choices about which trees to plant could make a real difference in supporting those bird populations .

Lilly 3:48

Yeah , absolutely .

Jad 3:49

So say , a city scores well in this first component . What about those ecosystem services you mentioned ?

Lilly 3:55

Yeah , so that's where things get really interesting , especially for you as arborists .

Jad 3:59

Okay .

Lilly 4:00

This component looks at all the tangible benefits that biodiversity brings to city dwellers Things like regulating water quantity , helping with climate regulation through trees and greenery , providing recreational opportunities in parks and even promoting the health and well-being of residents .

Jad 4:18

I can definitely see the connection to our work here . We're not just planting trees to make a city look pretty Right , our work here . Yeah , we're not just planting trees to make a city look pretty Right . We're directly contributing to a city's ability to manage water resources , cool down those urban heat islands and create spaces where people can connect with nature .

Lilly 4:34

You're hitting the nail on the head by thinking about these ecosystem services .

Jad 4:38

Yeah .

Lilly 4:38

Your work as arborists goes from simply tree care to shaping a healthier and more sustainable urban environment .

Jad 4:48

That's a powerful way to think about our role in the bigger picture of city planning . But what about that third component you mentioned ?

Lilly 4:54

Right .

Jad 4:55

The governance and management side of things .

Lilly 4:57

Yeah .

Jad 4:57

It sounds a bit more bureaucratic and less hands-on .

Lilly 5:00

It might seem that way at first .

Jad 5:02

Yeah .

Lilly 5:02

But it's equally important .

Jad 5:03

OK .

Lilly 5:04

This component delves into things like institutional capacity . Ok , so are there dedicated biodiversity centers , botanical gardens , research institutions focused on urban ecology ? It also assesses the budget allocated to biodiversity . So are they putting their money where their mouth ?

Jad 5:19

is when it comes to protecting urban ecology . It also assesses the budget allocated to biodiversity . So are they putting their money where their mouth is when it comes to protecting urban ?

Lilly 5:23

nature . Exactly , and perhaps most importantly , it examines whether a city has a local biodiversity strategy and action plan , a concrete roadmap for how they plan to protect and enhance their natural assets .

Jad 5:36

That sounds

Singapore Index: Understanding Urban Biodiversity

Jad 5:37

crucial .

Lilly 5:37

Yeah .

Jad 5:38

Without a plan , even the best intentions can get lost in the shuffle of city development .

Lilly 5:47

Absolutely , and this component also encourages cities to do something called natural capital assessments , okay , basically putting a tangible value on the benefits provided by nature .

Jad 5:54

It's like finally acknowledging that nature isn't just something nice to have .

Lilly 5:58

Right .

Jad 5:58

It's a vital part of our urban infrastructure and should be treated as such .

Lilly 6:02

You got it . And the fascinating thing is , the Singapore Index isn't static . It's actually been revised and updated to incorporate the latest trends in biodiversity conservation and climate change .

Jad 6:14

So it's a living document , constantly evolving to reflect the latest knowledge and best practices .

Lilly 6:21

Exactly . It's designed to be adaptable to a city's unique context , providing a framework for cities to make informed decisions about creating greener , healthier and more biodiverse urban environments .

Jad 6:33

I'm really starting to see the potential of the Singapore Index . Yeah , it's not just a theoretical tool , right , it's a practical guide . Theoretical tool , it's a practical guide for cities and for professionals like us to create a more sustainable future . You mentioned that cities use the Singapore Index as a self-assessment tool . What does that look like in practice ?

Lilly 6:51

So cities basically go through this detailed process of evaluating themselves against a set of indicators which are grouped under those three main components we talked about Native biodiversity , ecosystem services , and governance and management .

Jad 7:07

So it's like a checklist of best practices for urban biodiversity .

Lilly 7:11

That's a good way to put it , and one of the most important things to remember is it's not about getting a perfect score . It's about figuring out where a city is doing well and , more importantly , where they need to step up their game .

Jad 7:23

That makes sense . It's about using the index as a roadmap for action , not just a pat on the back .

Roger 7:28

Exactly .

Jad 7:29

Could you give me an example of what some of these indicators look like in the native biodiversity component ?

Lilly 7:33

Sure , let's take the indicator on connectivity measures . Remember how we talked about creating those wildlife highways to allow species to move freely throughout the city .

Jad 7:42

Yeah , the image of birds navigating a concrete jungle is a powerful one .

Lilly 7:47

Well , this indicator looks at how well a city's natural areas are linked , you know , through corridors , greenways and even just patches of suitable habitat in more developed areas .

Jad 7:56

Okay , so like stepping stones .

Lilly 7:58

Exactly .

Jad 7:58

I'm already seeing how this connects to my work as an arborist .

Lilly 8:01

Right .

Jad 8:02

If I'm planting trees along the street , for example , I could choose species that provide food and shelter for birds , creating those stepping stones for them to move through the city .

Lilly 8:11

That's the kind of thinking the Singapore Index encourages .

Jad 8:14

Yeah .

Lilly 8:14

Recognizing that every tree we plant can play a role in supporting biodiversity , even in those super urbanized environments .

Jad 8:21

OK , now I'm curious about the ecosystem services component . What are some examples of indicators that would be relevant to arborists ?

Lilly 8:30

One that jumps out is climate regulation , benefits of trees and greenery .

Jad 8:33

OK .

Lilly 8:34

This indicator measures the tree canopy cover in a city and how that canopy is being managed to deal with climate change .

Jad 8:41

Yeah , we all know trees are super important for absorbing carbon dioxide and releasing oxygen , but they also play a big role in cooling down cities .

Lilly 8:48

You're right . They provide shade , which helps reduce that urban heat island effect . The Singapore Index encourages cities to not just plant more trees but to manage existing trees in a way that maximizes those climate benefits .

Jad 9:01

So things like making sure there's a good variety of tree species and planting trees in places that will maximize shade .

Lilly 9:07

Exactly . It's about going beyond simply increasing the number of trees and thinking strategically about how we can use them to create

Ecosystem Services: Trees Beyond Beauty

Lilly 9:15

a more comfortable and climate resilient urban environment .

Jad 9:18

This is starting to make a lot of sense , yeah , but I'm wondering how the Singapore index deals with something as complicated as climate change . It seems like such a huge global issue . How can a city level tool really make a difference ?

Lilly 9:31

That's a great question . The index doesn't shy away from these big challenges . It actually has an indicator called biodiversity-related responses to climate change .

Jad 9:40

Okay , tell me more .

Lilly 9:41

So this indicator looks at how cities are using nature-based solutions , which often involve trees and green spaces , to both adapt to the impacts of climate change and reduce their own contributions to the problem .

Jad 9:52

Okay , can you give me a concrete example ?

Lilly 9:54

Sure . Think about the increasing risks of flooding because of sea level rise and more intense rainfall . A city might use the Singapore Index to assess how well they're protecting and restoring coastal wetlands .

Jad 10:06

Because those wetlands act like natural sponges , absorbing excess water and protecting the city from floods .

Lilly 10:11

Exactly , and the index also encourages cities to plant trees in a way that reduces the urban heat island effect , making the city more livable during those heat waves .

Jad 10:20

It seems like by incorporating these indicators , cities can really start to weave climate resilience into how they design their urban spaces , from parks and green spaces to streetscapes and even building codes .

Lilly 10:33

You're getting it . It's a holistic approach , and that's what makes the Singapore Index so powerful .

Jad 10:38

Now what about that third component governance and management ?

Lilly 10:41

Okay .

Jad 10:41

I'm still not quite clear on how that translates into real world action .

Lilly 10:45

So this is where we go , from the what to the how . We've been talking about how important things like connectivity , ecosystem services and climate resilience are .

Jad 10:51

Yeah .

Lilly 10:52

But this component focuses on the ways we actually made those things happen .

Jad 10:55

So it's about having the right policies , regulations and resources in place to support biodiversity .

Lilly 11:01

Exactly , and it looks at things like institutional capacity . Does the city have a dedicated department or agency focused on biodiversity ? Are there enough resources to actually put those nature-based solutions we talked about into action ?

Jad 11:16

So it's not enough to just want to do good . You need the infrastructure and support to actually get it done .

Lilly 11:22

Precisely , and one of the most important indicators in this component is having a local biodiversity strategy and action plan .

Jad 11:30

We touched on that earlier . It's about having a solid plan .

Lilly 11:33

Right . This is where a city lays out what they want to achieve with biodiversity , set specific goals and figures out the steps they'll take to get there .

Jad 11:41

It's like a blueprint for a biodiverse and sustainable city .

Lilly 11:44

Exactly , and the Singapore Index encourages cities to make this plan as all-encompassing as possible . Right Integrating biodiversity into everything from city planning to management .

Jad 11:54

So it's not just the Parks Department's job .

Lilly 11:56

Yeah .

Jad 11:56

It's about getting everyone involved Right Transportation planners , developers , community groups , even regular citizens .

Lilly 12:02

You got it it's about creating a culture of biodiversity , where protecting and enhancing nature is a shared responsibility .

Jad 12:10

This has been so insightful . I'm really starting to see how the Singapore Index can be such a useful tool .

Lilly 12:17

Yeah .

Jad 12:17

Not just for cities , but for professionals like me who work in urban environments .

Lilly 12:21

I'm glad to

Governance and Climate Action Solutions

Lilly 12:22

hear that . Now I'm excited to hear some examples of cities actually using this knowledge to make a difference . You know , it's one thing to have a framework like the Singapore Index , but it's a whole other thing to see it put into practice , and the good news is there are cities around the world using it to make real progress .

Jad 12:40

Awesome . Let's jump into some of those examples . What kind of success are we seeing out there ?

Lilly 12:44

Well , one city that comes to mind is Lisbon , portugal . After trying out the Singapore index , they realized they didn't have a clear plan for biodiversity conservation , so they went ahead and developed a local biodiversity strategy and action plan .

Jad 13:01

That's great . They really took the index and used it to make changes . What did that look like in practice ? What kinds of things did they change ?

Lilly 13:07

They did a lot of things .

Jad 13:09

Okay .

Lilly 13:09

Like improving how connected green spaces are .

Jad 13:13

Okay .

Lilly 13:13

Restoring ecosystems that had been degraded Right , and even starting citizen science programs to monitor biodiversity .

Jad 13:20

I bet those citizen science programs are a great way to get the whole community involved .

Lilly 13:24

Absolutely .

Jad 13:25

It's not just experts telling people what needs to happen .

Lilly 13:27

Right .

Jad 13:27

It's about everyone feeling responsible for taking care of their environment .

Lilly 13:31

Exactly , and Lisbon's efforts have paid off .

Jad 13:34

Oh , that's great .

Lilly 13:35

They've seen a big increase in bird species in the city .

Jad 13:38

Wow .

Lilly 13:39

And they've made this network of green corridors , which are good for wildlife .

Jad 13:43

Yeah .

Lilly 13:44

And give residents places to relax and enjoy nature .

Jad 13:48

Sounds like a win-win for everyone . Are there any other cities having success with the Singapore Index ?

Lilly 13:54

For sure . Another inspiring example is Curitiba , Brazil . They've been leaders in sustainable urban planning for years .

Jad 14:02

That's great .

Lilly 14:03

And they've used the Singapore Index to do even more .

Jad 14:05

What makes Curitiba so special ?

Lilly 14:07

Well , they have a really unique way of doing public transportation , which has helped to reduce traffic and air pollution .

Jad 14:13

Makes sense .

Lilly 14:14

And they've also put a lot of effort into making parks and green spaces all over the city .

Jad 14:19

It sounds like a city that really cares about its people .

Lilly 14:21

They do and you can see the results .

Jad 14:23

How so .

Lilly 14:23

They have more trees than average for a city their size .

Jad 14:26

Okay .

Lilly 14:27

And they've seen a big decrease in the urban heat island effect .

Jad 14:30

So I'm noticing something here . The cities that are doing well with the Singapore Index all seem to have one thing in common what's that they're all thinking about the bigger picture and making biodiversity a central part of how they plan their cities .

Lilly 14:44

You're absolutely right . It's not about treating nature as something extra or something separate from the city . It's about making it part of everything the city does . Happy International Day of Forests everyone , and thanks for joining us .

Jad 14:57

Yes , thank you for joining us for this deep dive into the world of urban biodiversity . Until next time keep exploring keep learning and keep diving deep .
