00:00:00,148 --> 00:00:04,292
One of the big pushes about restoration is restoring coastlines
2
00:00:04,872 --> 00:00:08,736
with carbon sequestering type
3
00:00:08,896 --> 00:00:12,479
habitats, but also habitats that will protect the shoreline, will
4
00:00:12,599 --> 00:00:16,323
increase biodiversity, and will have economic
5
00:00:16,503 --> 00:00:20,046
as well as environmental impacts for a long time.
6
00:00:20,667 --> 00:00:24,569
But all of those different reasons to restore
7
00:00:24,589 --> 00:00:28,291
a coastline, they don't always align. And sometimes
8
00:00:28,391 --> 00:00:32,133
it gets in the way of actual proper restoration of
9
00:00:32,173 --> 00:00:35,434
a coastline. So we're gonna talk about Thailand, and we're gonna talk
10
00:00:35,454 --> 00:00:38,936
about the budding mangrove restoration, and some of the concerns that surround
11
00:00:38,996 --> 00:00:42,818
it with blue carbon, some private and public
12
00:00:43,178 --> 00:00:46,499
partnerships, and where and how restoration is
13
00:00:46,659 --> 00:00:49,721
actually done. We're gonna talk about that on today's episode of the How to
14
00:00:49,741 --> 00:00:56,382
Protect the Ocean podcast. Let's start the show. Hey
15
00:00:56,402 --> 00:00:59,783
everybody welcome back to another exciting episode of the How to Protect the Ocean podcast. I'm
16

your host Andrew Lewin and this is a podcast where you find out what's happening with the ocean,
17
00:01:03,324 --> 00:01:06,384
how you can speak up for the ocean, and what you can do to live for a
18
00:01:06,444 --> 00:01:09,905
better ocean by taking action. This is where you find all things
19
00:01:10,065 --> 00:01:13,206
about the ocean and you can find out more information if you go

27
00:01:53,098 --> 00:01:56,380
Thailand and I want you to just be a little patient, sit back and
28
00:01:56,440 --> 00:01:59,923
just listen to what I'm going to say for this episode
29
00:01:59,943 --> 00:02:03,385
because there's a lot to get through and there's a lot of things
30
00:02:03,425 --> 00:02:06,912
that we have to consider. And I'm really glad this article was written by Carolyn Cowan
31
00:02:06,992 --> 00:02:10,358
from Among the Bay. And I'm going to link to the article
32
00:02:10,458 --> 00:02:14,273
in the show notes as well as the description if you're watching this on YouTube. there's
33
00:02:14,293 --> 00:02:17,457
a lot to know about restoration there's a
34
00:02:17,517 --> 00:02:20,900
lot that goes into restoration and there's a lot of things that could be good and
35
00:02:21,001 --> 00:02:24,765
bad when it comes to restoration some of those are the outside
36
00:02:25,165 --> 00:02:28,469
pressures that come with you know trying to
37
00:02:28,509 --> 00:02:31,912
do better for the planet we know we are in it right
38
00:02:32,032 --> 00:02:35,335
now for the the planet, right? We are
39
00:02:35,456 --> 00:02:39,038
seeing a lot of problems. We have observed climate change on
40
00:02:39,159 --> 00:02:42,741
countless different fronts, from droughts to wildfires, to
41
00:02:42,801 --> 00:02:46,905
sea level rise, to increased storm surges, more flooding, more
42
00:02:46,965 --> 00:02:50,668
rainfall, hotter ocean surfaces,
43
00:02:51,348 --> 00:02:55,031
like record-breaking. And it doesn't look like it's going to stop anytime
44
00:02:55,071 --> 00:02:58,706
soon. Some of the things that we can do are restore habitats
45
00:02:58,786 --> 00:03:02,268
to decrease the effects of climate change and reduce climate change
46
00:03:02,308 --> 00:03:06,070
and greenhouse gases by sequestering more carbon. But
47
00:03:06,110 --> 00:03:09,332
what we can also do is protect the coastlines more, just as
48
00:03:09,392 --> 00:03:14,034
they originally did when these coastlines were intact. They
49
00:03:14,094 --> 00:03:17,477
provided not only security from tsunamis or storm
50
00:03:17,517 --> 00:03:20,680
surges, but they provided biodiversity so that
51
00:03:20,700 --> 00:03:24,243
people can fish and people can live off and enjoy the
52
00:03:24,323 --> 00:03:27,986
fruits of the labor of having healthy mangroves,
53
00:03:28,066 --> 00:03:31,429
and also just a stable ecosystem, which again, provides
54
00:03:31,489 --> 00:03:35,252
security, provides natural resources ability, and
55
00:03:35,292 --> 00:03:38,434
just makes everything better. Let's be honest, it just
56
00:03:38,474 --> 00:03:42,415
makes everything better. So today we're gonna be talking about Thailand's
57
00:03:43,115 --> 00:03:46,696
mangrove restoration projects and their plans, and how
58
00:03:46,736 --> 00:03:50,116
it can benefit them, but how some of the things that happen through
59
00:03:50,176 --> 00:03:53,337
restoration, through different pressures and
60
00:03:53,377 --> 00:03:56,718
different, I guess, opportunities and projects, have not
61
00:03:56,858 --> 00:04:00,098
been as fruitful as hoped. And so we're gonna talk about that.
62
00:04:00,158 --> 00:04:04,379
But before we get into that, I want you to understand that
63
00:04:04,539 --> 00:04:08,340
restoration, one, is expensive. Protection is
64
00:04:08,420 --> 00:04:11,560
better. It's cheaper, it's longer lasting, and
65
00:04:11,600 --> 00:04:15,641
it's better. But no matter what you choose, protection, restoration,
66
00:04:16,421 --> 00:04:19,882
you always have to start somewhere. And even though we're
67
00:04:19,902 --> 00:04:23,382
gonna be talking about some problems that are going on with these
68
00:04:23,462 --> 00:04:26,823
plans and with these projects over time, the strategy is the same,
69
00:04:27,223 --> 00:04:30,384
is to continue to do things, continue to
70
00:04:30,444 --> 00:04:33,765
restore, continue to protect. Be able
71
00:04:33,825 --> 00:04:36,927
to find out the problems, adapt to those problems, and be able to
72
00:04:37,087 --> 00:04:40,389
manage those problems better in the future by
73
00:04:40,469 --> 00:04:43,711
just switching up the strategy. So none
74
00:04:43,731 --> 00:04:46,913
of these projects should be vilified. None of
75
00:04:46,953 --> 00:04:50,195
these projects should be saying, hey, you know what, we can't do this
76
00:04:50,255 --> 00:04:53,917
restoration because there's always these little problems here and there. No,
77
00:04:53,997 --> 00:04:57,181
these problems happen when you start to do action. And
78
00:04:57,221 --> 00:05:00,564
that's what we're talking about today is we're talking about action.
79
00:05:00,904 --> 00:05:04,408
And that's sort of what I want to focus on is the action.
80
00:05:04,528 --> 00:05:07,651
And so I want you to remember when I talk about a lot of these
81
00:05:07,671 --> 00:05:10,954
things, and I identify some of the shortcomings of
82
00:05:11,014 --> 00:05:14,318
these plans that, you know what, Thailand's doing a great job. The people
83
00:05:14,338 --> 00:05:17,740
of Thailand are doing a great job at forwarding this
84
00:05:17,821 --> 00:05:21,462
restoration, okay? So there's a number of things that we need to consider when
85
00:05:21,502 --> 00:05:24,804
we're restoring. Some things are a little bit higher priority than others,
86
00:05:25,324 --> 00:05:28,626
but overall, there's still things that you can change and there's still things that you can
87
00:05:28,706 --> 00:05:32,068
manage. So this is a great article. I highly recommend that you
88
00:05:32,088 --> 00:05:35,289
take some time and read it. It's something that I
89
00:05:35,469 --> 00:05:38,991
always love from Mongabay. The authors put in so much detail
90
00:05:39,051 --> 00:05:42,833
and it's so great. And this article starts off with
91
00:05:43,133 --> 00:05:46,595
speaking to someone who is uh... disorderly
92
00:05:46,756 --> 00:05:50,278
the through the keeper of this education center
93
00:05:50,759 --> 00:05:54,081
unnatural services called the mangrove nature school in
94
00:05:54,141 --> 00:05:57,424
bangku a village roughly two hours drive south
95
00:05:57,524 --> 00:06:01,287
of bangkok uh... and so in this uh... summit song
96
00:06:01,307 --> 00:06:04,429
of groom uh... province i apologize if i'm not pronouncing this
97
00:06:04,449 --> 00:06:07,612
properly i'm not very familiar with the pronunciation for a lot of
98
00:06:07,652 --> 00:06:11,375
these places here in in thailand uh... but
99
00:06:12,255 --> 00:06:16,218
So there's a huge area of,
100
00:06:16,599 --> 00:06:19,761
well not huge I guess, but larger area of mangroves that are on
101
00:06:19,801 --> 00:06:22,903
this preserve. It's been preserved for over three decades. It's a
102
00:06:23,804 --> 00:06:27,086
6.5 hectare or 15.8 acres of patch of
103
00:06:27,126 --> 00:06:32,392
mangrove forest that is next to this person's village. Being
104
00:06:32,452 --> 00:06:36,635
able to have that, you have mudskippers, iridescent fiddler
105
00:06:36,656 --> 00:06:40,599
crabs that flip between the tangled
106
00:06:40,659 --> 00:06:44,181
roots of a pair of seven and a half meter or 25 foot
107
00:06:44,241 --> 00:06:48,264
mangrove trees as the tide laps relentlessly beneath the raised
108
00:06:48,324 --> 00:06:54,378
walkway. So you get a little bit of a description of what happens in there. When
109
00:06:54,638 --> 00:06:57,801
they start to look at this coastline, they start to see
110
00:06:57,921 --> 00:07:02,105
a reminder that there is some eroding
111
00:07:02,225 --> 00:07:05,688
of the coastline that's rapidly eroding. And Thailand's
112
00:07:05,708 --> 00:07:08,831
Department of Marine and Coastal Resource Management estimates that parts of
113
00:07:09,592 --> 00:07:13,375
the Gulf of Thailand lose up to 5 meters or 16 feet
114
00:07:13,395 --> 00:07:16,578
of land to the sea level rise per year. We're going to talk about
115
00:07:16,638 --> 00:07:20,381
sea level rise as well as coastal development in a little bit. Now
116
00:07:20,441 --> 00:07:23,622
I want to go a bit into the history of
117
00:07:23,642 --> 00:07:27,103
Thailand's mangrove areas and
118
00:07:27,363 --> 00:07:31,444
the sort of degradation that we've seen over
119
00:07:31,524 --> 00:07:35,105
that time because I think it's important to have sort
120
00:07:35,145 --> 00:07:38,606
of a knowledge of where they were, where they've been, and how
121
00:07:38,666 --> 00:07:42,226
it's going right now. So in 1961 there was estimate coverage
122
00:07:42,366 --> 00:07:50,469
that was at 350,000 hectares
123
00:07:50,629 --> 00:07:54,510
in 1961 and it dropped to 160,000 hectares by
124
00:07:55,891 --> 00:07:59,232
1996. So that's a huge, huge drop. So
125
00:07:59,672 --> 00:08:03,074
in 1996, they realized, hey, hold on a second, we need to build
126
00:08:03,154 --> 00:08:06,495
up our mangroves because they provide a lot of
127
00:08:06,555 --> 00:08:09,696
services. So they provide, first of all, security. So
128
00:08:09,756 --> 00:08:13,738
when a tsunami comes through, the areas that have intact
129
00:08:13,978 --> 00:08:17,340
mangrove habitats dispel the energy, right?
130
00:08:17,380 --> 00:08:20,722
They basically dissipate that energy of waves that comes over the
131
00:08:20,762 --> 00:08:24,304
top and through the mangroves so that by the time it gets to some
132
00:08:24,324 --> 00:08:27,866
of the villages and towns that are beyond the mangrove areas,
133
00:08:27,886 --> 00:08:31,888
like that 50 meter swath that they like to keep in Thailand, then
134
00:08:31,908 --> 00:08:35,270
the energy is a lot less, the destruction is a lot less,
135
00:08:35,370 --> 00:08:38,651
lives are saved. and it's a lot better. So having an
136
00:08:38,771 --> 00:08:42,452
intact and healthy mangrove forest is good from
137
00:08:42,472 --> 00:08:45,553
a, or is great from a security standpoint. It's also great from a
138
00:08:45,633 --> 00:08:48,894
biodiversity standpoint. There's lots of fishing that can go
139
00:08:49,054 --> 00:08:52,995
on. It can feed local fishing villages for
140
00:08:53,015 --> 00:08:57,075
a lifetime and more in generations if you have that healthy area,
141
00:08:57,315 --> 00:09:00,616
right? Plus you have the diversity, you get a lot of birds. Having
142
00:09:00,676 --> 00:09:04,297
biodiverse areas is meaning you have a stable coastline.
143
00:09:04,797 --> 00:09:08,198
Meaning that, you know, when you have all these different animals that
144
00:09:08,258 --> 00:09:11,599
take part in sort of taking care of
145
00:09:11,679 --> 00:09:15,140
these habitats, you know, from making sure that invasive
146
00:09:15,180 --> 00:09:18,381
species get eaten and taken away, or
147
00:09:18,541 --> 00:09:22,102
that certainly everything is all balanced and stable, then you
148
00:09:22,122 --> 00:09:25,278
start to have some good things happening there. So
149
00:09:25,318 --> 00:09:28,783
that's all good from there. So having a biodiverse area, healthy
150
00:09:28,923 --> 00:09:32,147
mangroves that can help with security is
151
00:09:32,187 --> 00:09:35,511
a huge, huge impact. Then there's also the carbon
152
00:09:35,551 --> 00:09:39,196
credits that you can get, that they're a carbon sink. So they sequester
153
00:09:39,236 --> 00:09:42,681
carbon by continuing to build and regrow
154
00:09:42,721 --> 00:09:46,023
and regenerate through mangroves, mangrove trees.
155
00:09:46,043 --> 00:09:49,504
They are a tree, and they tend to sequester four times the
156
00:09:49,544 --> 00:09:53,745
amount of, up to four times, maybe even more, of regular
157
00:09:53,786 --> 00:09:57,007
trees that we normally talk about when we talk about blue carbon projects. So
158
00:09:57,287 --> 00:10:00,648
they are a blue carbon community, a habitat, and something that
159
00:10:00,728 --> 00:10:04,069
we need to focus on. We did talk, and I'll put the link in the show notes,
160
00:10:04,749 --> 00:10:08,010
recently with World Economic Forum about
161
00:10:08,111 --> 00:10:11,652
one of their projects to restore mangroves in a lot of different places in
162
00:10:11,672 --> 00:10:15,213
the tropics. And, you know, so that it's obviously
163
00:10:15,333 --> 00:10:19,115
a worldwide and global initiative to do this, but in Thailand,
164
00:10:19,175 --> 00:10:26,698
it's big. Now, 160,000 acres down in or down to 160,000 acres in 1996. The
165
00:10:27,039 --> 00:10:30,262
response to that and the increase in
166
00:10:30,743 --> 00:10:34,247
planting these types of mangroves increased by
167
00:10:36,049 --> 00:10:39,252
50%. By the time, I think it was 2000 and,
168
00:10:39,272 --> 00:10:42,376
so here it is right here, or
169
00:10:43,457 --> 00:10:48,301
I guess right now, 2024, now has 248,400 mangroves. hectares
170
00:10:48,402 --> 00:10:52,163
so it's a 50% increase of mangrove cover according
171
00:10:52,223 --> 00:10:55,865
to UNESCO figures which is great that's a 50% of
172
00:10:55,905 --> 00:10:59,027
coverage from 1996 that's big and
173
00:10:59,067 --> 00:11:02,229
is a 400 sorry 46,400 of
174
00:11:02,269 --> 00:11:05,730
those acres are managed for conservation as natural national
175
00:11:05,770 --> 00:11:09,292
parks or wildlife sanctuaries so that's a big bonus
176
00:11:09,312 --> 00:11:12,774
so we are seeing an increase in the coverage now
177
00:11:12,854 --> 00:11:16,452
here's the thing we are seeing a mass
178
00:11:16,512 --> 00:11:20,436
plantings happening and this is a lot of private and public sort
179
00:11:20,476 --> 00:11:23,779
of partnerships that are happening where you will get companies who
180
00:11:23,819 --> 00:11:27,243
are saying hey you know what we've planted a certain amount of trees a
181
00:11:27,263 --> 00:11:30,566
certain amount of mangrove trees along this coastline and we've done this
182
00:11:30,626 --> 00:11:33,708
and we've done that and the And it's great and
183
00:11:33,748 --> 00:11:37,450
you get the companies that are being part of restoring the coastline, protecting
184
00:11:37,490 --> 00:11:41,091
Thailand, protecting people along those coastlines and
185
00:11:41,351 --> 00:11:44,992
just the nature of it all, the biodiversity, that
186
00:11:45,032 --> 00:11:48,273
makes businesses feel good. It also shows that they're doing some good things and
187
00:11:48,333 --> 00:11:51,494
it's good for their PR. And we've seen in the
188
00:11:51,534 --> 00:11:55,235
history of Thailand, in the past, we've seen a lot of degradation and
189
00:11:55,295 --> 00:11:58,937
removal for building like shrimp farms and development stuff.
190
00:11:58,977 --> 00:12:03,498
And so now to see these coastlines being naturalized is
191
00:12:03,518 --> 00:12:06,720
a good thing, right? We're starting to see that. And companies that
192
00:12:06,760 --> 00:12:09,962
are partnering with the government to be able to
193
00:12:10,002 --> 00:12:14,024
put these programs and have permission to plant in certain areas is
194
00:12:14,085 --> 00:12:17,206
a benefit, right? To see that. So you'll see a sloth of in
195
00:12:17,266 --> 00:12:21,249
pictures that this company is putting together of these little mango shoots
196
00:12:21,269 --> 00:12:25,031
that are about yay big, you know, maybe a foot, foot and a half high, and
197
00:12:25,231 --> 00:12:28,953
they're being planted in rows and they're like, you know, planted together and
198
00:12:29,213 --> 00:12:32,455
so forth. And then all of a sudden, They
199
00:12:32,495 --> 00:12:35,818
forget about it. They stop posting about it. They've planted their stuff, they've
200
00:12:35,858 --> 00:12:39,680
done their thing, and they stop posting about it. Here's the
201
00:12:39,780 --> 00:12:43,163
one of the concerns that's coming through, is where these trees
202
00:12:43,203 --> 00:12:46,445
are being planted, where these mangrove seedlings are being planted. They're not being
203
00:12:46,485 --> 00:12:49,968
planted in the right areas. They're being planted in areas that gets washed over
204
00:12:50,028 --> 00:12:53,410
by the tide, and at the time for those seedlings, they get drowned.
205
00:12:53,811 --> 00:12:57,313
They can actually drown, and they can get destroyed. And so these shoots
206
00:12:57,773 --> 00:13:01,636
that you see will eventually die because they will they
207
00:13:01,656 --> 00:13:04,899
will die. They will drown. They won't get enough. They won't get enough air.
208
00:13:05,219 --> 00:13:08,722
They won't get enough, uh, non coverage of ocean and
209
00:13:08,782 --> 00:13:12,285
they will dissipate and they will get destroyed. So all that money
210
00:13:12,485 --> 00:13:15,688
that was put into, you know, grow the seedlings and
211
00:13:15,708 --> 00:13:19,050
to create the seedlings and, uh, bring them over to certain
212
00:13:19,130 --> 00:13:22,533
areas, the time it takes and the team building it does for these
213
00:13:22,573 --> 00:13:25,736
companies and the feel good, all that work, all that effort, all
214
00:13:25,776 --> 00:13:29,259
that money washed away with the ocean, literally washed
215
00:13:29,319 --> 00:13:33,036
away. So these efforts are
216
00:13:33,116 --> 00:13:36,736
not as good as that first preserve that we talked about at
217
00:13:36,776 --> 00:13:40,177
the beginning of this show, when I went through it, where
218
00:13:40,237 --> 00:13:43,618
it's like 6.4 hectares of mangrove forest that
219
00:13:44,038 --> 00:13:47,419
is planted carefully, is planted together so
220
00:13:47,459 --> 00:13:50,660
that the roots intertwine, so that they're
221
00:13:50,700 --> 00:13:54,461
stronger together, that are planted in specific areas
222
00:13:54,721 --> 00:13:57,841
where the ocean's not gonna wash over them as
223
00:13:57,881 --> 00:14:01,723
they're growing and not gonna kill them. When
224
00:14:01,743 --> 00:14:04,925
we talk about restoration, this is what I talked about at the beginning, is that there
225
00:14:04,965 --> 00:14:08,127
are certain places where you will restore, there are certain places where
226
00:14:08,167 --> 00:14:11,309
you won't restore, and it does not matter if there were mangroves that were
227
00:14:11,349 --> 00:14:14,751
there before. The fact that there's been a lack of mangroves for
228
00:14:17,212 --> 00:14:21,055
10, 20, 30, 40 years could make that historic
229
00:14:21,095 --> 00:14:25,398
site not appropriate for planting
230
00:14:25,438 --> 00:14:28,760
mangroves anymore or for a mangrove habitat because it changes over time.
231
00:14:29,418 --> 00:14:32,601
You know, if you don't have mangroves, you don't have the land because that
232
00:14:32,641 --> 00:14:36,103
gets eroded away from the water, from the ocean, and from the tides coming
233
00:14:36,143 --> 00:14:39,426
in and out. So you don't have that space. That's
234
00:14:39,486 --> 00:14:42,849
gone. You know, the fact that sea level is rising in
235
00:14:42,869 --> 00:14:46,392
a lot of these island areas and the fact that there is less
236
00:14:46,532 --> 00:14:49,834
of a stability because of lack of mangroves can change an area.
237
00:14:49,854 --> 00:14:53,677
So something that was historically a mangrove habitat 30 years
238
00:14:53,737 --> 00:14:57,459
ago 40 years ago even 10 years ago may not be appropriate to
239
00:14:57,499 --> 00:15:00,661
be a mangrove habitat now and may need to be built up
240
00:15:00,741 --> 00:15:04,103
which can take a lot more money and a lot more time to do but
241
00:15:04,203 --> 00:15:07,465
just being just saying hey we're just going to plant these areas
242
00:15:07,505 --> 00:15:10,646
because this company was going to pay for a lot of that and they want to
243
00:15:10,746 --> 00:15:13,848
be a part of this that may not be the best area. So there
244
00:15:13,868 --> 00:15:17,091
needs to be better coordination of planning and the sites that need
245
00:15:17,111 --> 00:15:20,553
to do this. Now I'm a former GIS guy. I'm still a GIS guy,
246
00:15:20,593 --> 00:15:23,776
but I used to work in GIS and a lot of times when we talked about
247
00:15:23,836 --> 00:15:27,218
restoration, we would look at suitable areas.
248
00:15:27,258 --> 00:15:30,401
We'd have a map of the area, whether it be a coastline, whether it be on land. I
249
00:15:30,441 --> 00:15:33,923
did a lot of different things. We would look, okay, here
250
00:15:34,183 --> 00:15:37,726
are the attributes of an area that we're considering to
251
00:15:37,786 --> 00:15:41,088
restore or a number of areas that we're considering to restore. We would look
252
00:15:41,108 --> 00:15:44,631
at that attribute and we would look at, we'd basically do like a prediction model
253
00:15:44,691 --> 00:15:48,033
saying which areas would be the best, would have the best
254
00:15:48,073 --> 00:15:51,636
success rate of holding on to a mangrove for
255
00:15:51,676 --> 00:15:54,818
a longer period of time. So, it's not just that you plant it and
256
00:15:54,838 --> 00:15:58,241
a year later, all those seedlings are gone. It's you plant
257
00:15:58,321 --> 00:16:01,643
it and a year later, they're still there. Another year later, they're still there. Five
258
00:16:01,663 --> 00:16:04,965
years down the road, it's growing into a bigger mangrove area.
259
00:16:05,586 --> 00:16:09,028
Ten years down the road, all right, now we have an established area. We're starting to see more
260
00:16:09,108 --> 00:16:13,171
biodiversity of ocean animals that are there and mangrove animals, land
261
00:16:13,311 --> 00:16:16,714
and, you know, we're starting to see like birds, coastal birds and seabirds come
262
00:16:16,794 --> 00:16:20,196
out. We're starting to see like nursing areas starting to develop, nursery
263
00:16:20,276 --> 00:16:23,799
areas. These are really important. The longevity of
264
00:16:23,839 --> 00:16:27,822
that growth and seeing that habitat
265
00:16:27,902 --> 00:16:31,725
evolve and build on the security
266
00:16:31,785 --> 00:16:34,987
of that area and the stability of that area is
267
00:16:35,027 --> 00:16:38,310
great to see, but you have to give it time. It's going to take time. You can't just
268
00:16:38,470 --> 00:16:42,353
plant for the sake of planting and not being able to come
269
00:16:42,393 --> 00:16:45,856
back a year later and seeing the fruits of your labor, the fruits of
270
00:16:45,896 --> 00:16:49,138
the funding that's been put into it, and the actual labor that's been put
271
00:16:49,178 --> 00:16:52,340
into it. where you plant is a
272
00:16:52,380 --> 00:16:55,582
big thing. And so there needs to be a little bit better coordination and
273
00:16:55,642 --> 00:16:58,905
identification of candidate sites that are good to
274
00:16:58,965 --> 00:17:02,327
restore. So you're not just throwing away money for the sake of
275
00:17:03,207 --> 00:17:06,430
greenwashing, essentially, right? Because these companies, although they may not
276
00:17:06,470 --> 00:17:09,972
want to greenwash, they want to see the success, they don't necessarily follow
277
00:17:09,992 --> 00:17:13,234
the success. So having programs where the companies can be in
278
00:17:13,274 --> 00:17:16,496
it for the long run, like in it to win it really, to see
279
00:17:16,536 --> 00:17:19,777
that win and be able to report on that or be able to
280
00:17:19,857 --> 00:17:23,119
show that through social media or through, you know, talking to their clients or
281
00:17:23,239 --> 00:17:27,801
whatever business they're in. Being able to show success could
282
00:17:28,261 --> 00:17:31,543
really further these projects more. And when you have mangroves that
283
00:17:31,583 --> 00:17:35,324
are established, when you have mangroves that have been around for a while and that provide
284
00:17:35,344 --> 00:17:38,646
that security, provide that biodiversity benefit, then you start to
285
00:17:38,706 --> 00:17:42,368
see the social impacts and the environmental impacts quite
286
00:17:42,408 --> 00:17:45,681
quickly. And that is an important part of
287
00:17:45,741 --> 00:17:49,204
this area. The second problem that we've seen, and
288
00:17:49,264 --> 00:17:52,427
I told you to stay with me here, the second problem that we've seen is the
289
00:17:52,467 --> 00:17:55,810
fact that it's the same mangrove, the red mangroves, that
290
00:17:55,851 --> 00:17:58,993
are being chosen to basically be
291
00:17:59,053 --> 00:18:02,797
planted. So now you have a monoculture of habitat
292
00:18:02,917 --> 00:18:06,180
of mangroves. And some of these areas did not
293
00:18:06,260 --> 00:18:09,652
have red mangroves in the first place. right? Some
294
00:18:09,672 --> 00:18:12,934
of these areas had different types of mangroves. But
295
00:18:12,974 --> 00:18:16,396
the thing is, is that mangroves from a restoration practice is
296
00:18:16,576 --> 00:18:20,178
easier to grow, is faster to grow and faster to establish no matter where
297
00:18:20,238 --> 00:18:23,380
it is within, say in this case, in Thailand. So the
298
00:18:23,420 --> 00:18:26,782
red mangrove can actually grow faster, establish itself faster. So
299
00:18:26,802 --> 00:18:30,125
there's a good and bad thing in this. The good thing is that a lot of the times,
300
00:18:30,185 --> 00:18:33,588
from the government perspective, they want to provide security in case a tsunami comes
301
00:18:33,628 --> 00:18:36,931
in. We don't know when tsunamis are going to come in. The 2004 Christmas
302
00:18:36,951 --> 00:18:40,053
tsunami was one of those situations where it
303
00:18:40,093 --> 00:18:43,416
impacted a huge swath of people in Southeast Asia,
304
00:18:44,077 --> 00:18:47,640
and it killed a lot of people. And if you didn't have mangroves
305
00:18:47,780 --> 00:18:51,039
in your area restored, You were in trouble. But
306
00:18:51,079 --> 00:18:54,403
if you did, you weren't in as much of trouble and
307
00:18:54,423 --> 00:18:58,047
the damage wasn't as bad. And often places
308
00:18:58,127 --> 00:19:02,451
saving, you know, villages and towns and people. But
309
00:19:02,511 --> 00:19:06,075
if you, so here's the tugging, the
310
00:19:06,255 --> 00:19:09,652
pulling and tugging of this or push and pull of this. is
311
00:19:09,692 --> 00:19:13,233
the fact that when you are trying
312
00:19:13,273 --> 00:19:16,514
to restore for protection, you want to do it as fast as possible. The
313
00:19:16,554 --> 00:19:20,256
faster situation here is to have a monoculture of red mangroves to
314
00:19:20,276 --> 00:19:23,417
put up. This may not be the mangrove of the day. It may
315
00:19:23,477 --> 00:19:26,858
not be the mangrove that would do better in the soil, in
316
00:19:26,878 --> 00:19:30,379
the area that is being planted. But it does grow.
317
00:19:30,479 --> 00:19:34,540
And it's sort of more resilient than other species. So
318
00:19:34,560 --> 00:19:38,062
you're having this monoculture being built right off the bat and being planted and
319
00:19:38,082 --> 00:19:41,402
being established. But the good news is that you can start
320
00:19:41,442 --> 00:19:44,683
planting other species as that sort
321
00:19:44,723 --> 00:19:48,604
of forest, mangrove forest grows and is established, right?
322
00:19:48,624 --> 00:19:51,865
So the first thing is to get it up for security. The second thing is
323
00:19:51,885 --> 00:19:55,306
to prioritize for diversity of mangroves because
324
00:19:55,326 --> 00:19:58,667
you never know, you know, we've seen it here in Canada a lot of times and
325
00:19:58,687 --> 00:20:02,207
in the States, once you have like an invasive species come through and there's one
326
00:20:02,267 --> 00:20:05,533
species of tree that gets affected, it
327
00:20:05,553 --> 00:20:08,975
will destroy all those species. So you're not going to have forests
328
00:20:09,035 --> 00:20:12,196
that are a monoculture of
329
00:20:12,236 --> 00:20:15,497
a certain species, because if that species is affected, that entire forest is gone. So
330
00:20:15,517 --> 00:20:18,839
it's better to have diverse forests with different tree
331
00:20:18,879 --> 00:20:22,140
species, just like it would be for mangrove species. I
332
00:20:22,520 --> 00:20:26,543
don't know much about mangroves and invasive species, and I don't know if that's as
333
00:20:27,203 --> 00:20:31,425
prevalent as it is in forests here in Canada, but
334
00:20:31,525 --> 00:20:34,867
it can be pretty devastating. So if there is something like that, that's
335
00:20:34,887 --> 00:20:38,089
something you have to be careful of. Biodiversity in any
336
00:20:38,149 --> 00:20:41,831
kind of situation is much better, whether
337
00:20:41,851 --> 00:20:45,513
it comes from nature, animals, or even people. So we
338
00:20:45,533 --> 00:20:48,724
should consider that more. Regardless, that is
339
00:20:48,864 --> 00:20:52,566
one of the downfalls of trying to build and create and
340
00:20:52,606 --> 00:20:55,867
establish a mangrove forest that is diverse, that
341
00:20:55,927 --> 00:20:59,068
is long lasting, and that can help. But when you're trying to
342
00:21:00,048 --> 00:21:03,529
protect for security, you want that 50 meter swath
343
00:21:04,109 --> 00:21:07,390
of mangrove forest from the coastline that will
344
00:21:07,450 --> 00:21:10,551
help protect against any kind of tsunamis. So
345
00:21:10,591 --> 00:21:13,743
that's another one of those problems. Now the
346
00:21:13,783 --> 00:21:17,244
third and final sort of concern that we have is
347
00:21:17,344 --> 00:21:20,806
the fact that we're starting to see a lot of companies and a lot of governments start
348
00:21:20,846 --> 00:21:25,227
to jump on this blue carbon train. And
349
00:21:26,007 --> 00:21:29,409
the situation of blue carbon is really interesting. From
350
00:21:29,469 --> 00:21:32,930
a perspective of reestablishing blue carbon
351
00:21:32,970 --> 00:21:36,431
habitats, so you have mangroves, seagrasses, salt
352
00:21:36,491 --> 00:21:40,561
marshes, and so forth, these are areas
353
00:21:40,622 --> 00:21:44,144
that could sequester multiple
354
00:21:44,184 --> 00:21:48,346
times more carbon than regular
355
00:21:48,486 --> 00:21:51,628
plants and trees, right? So like land plants and
356
00:21:51,648 --> 00:21:55,210
trees. So it's important to have these blue carbon habitats along
357
00:21:55,250 --> 00:21:58,332
the coastline. Now the problem is that they're along the coastline. And a
358
00:21:58,372 --> 00:22:01,564
lot of times the coastline has been altered in
359
00:22:01,624 --> 00:22:05,586
many places around the world so that it is good
360
00:22:05,646 --> 00:22:08,907
for coastal housing and residences or
361
00:22:09,067 --> 00:22:12,408
hotels and tourism or things like that. But you still
362
00:22:12,468 --> 00:22:15,950
need those habitats in there, like I said, for security. They have multiple benefits.
363
00:22:15,970 --> 00:22:19,211
But the blue carbon benefit is that it can sequester more
364
00:22:19,271 --> 00:22:22,652
carbon, help us with reducing the amount of carbon
365
00:22:22,672 --> 00:22:26,254
dioxide that is in the atmosphere. So having
366
00:22:26,534 --> 00:22:30,076
more of those blue carbon habitats planted is better. But
367
00:22:30,436 --> 00:22:33,498
there's a bit of a greenwashing train, as there always is with a
368
00:22:33,538 --> 00:22:36,921
lot of private companies who are putting money into projects that
369
00:22:37,041 --> 00:22:40,243
may or may not be real in some cases, or they could be
370
00:22:40,323 --> 00:22:43,885
putting into projects where the location,
371
00:22:43,905 --> 00:22:47,127
just as I mentioned before, may not have been chosen right, but they can say, hey,
372
00:22:47,167 --> 00:22:51,210
we're doing stuff for carbon sequestration and we're establishing
373
00:22:51,250 --> 00:22:55,112
more blue carbon habitats, but they don't stay for a long time. Right?
374
00:22:55,393 --> 00:22:59,077
And so there's a push to do this type of work, but again,
375
00:22:59,237 --> 00:23:02,661
location matters and trying to figure out which location is
376
00:23:02,701 --> 00:23:06,225
the best is a big thing. So having more
377
00:23:06,265 --> 00:23:09,889
blue carbon habitats will be better, but you have to be careful of
378
00:23:09,909 --> 00:23:13,714
the game of blue carbon. There's also carbon sequestration,
379
00:23:14,114 --> 00:23:17,318
which is like, do we sink plants? And do we
380
00:23:17,438 --> 00:23:21,063
sink these seaweed type materials and
381
00:23:21,103 --> 00:23:24,787
aquatic plants and coastal plants that could absorb
382
00:23:24,807 --> 00:23:28,031
way more carbon than land plants and trees? And we
383
00:23:28,111 --> 00:23:31,847
sink them into the ocean to bury that carbon. That
384
00:23:31,927 --> 00:23:35,188
has not been perfected by any means. And there are very
385
00:23:35,288 --> 00:23:38,989
few projects that are going on that I know of that are successful in
386
00:23:39,209 --> 00:23:42,490
establishing that. And it's still in its early stages of
387
00:23:42,530 --> 00:23:46,270
doing that. We don't know the effect of sinking seaweed
388
00:23:46,370 --> 00:23:49,491
on mass levels in specific areas, the effect that
389
00:23:49,511 --> 00:23:52,592
that will have on the deep sea. Just like we don't know what the
390
00:23:52,612 --> 00:23:55,753
effect is on deep sea mining, on the deep sea, we don't know
391
00:23:55,773 --> 00:23:58,933
the effect of sinking all the seaweed and what that's going to do in
392
00:23:58,953 --> 00:24:02,034
the future for our deep sea. So a
393
00:24:02,074 --> 00:24:05,196
lot of the carbon sequestration, blue carbon, you have to
394
00:24:05,236 --> 00:24:09,078
be careful, although this is a very big key word within
395
00:24:09,098 --> 00:24:12,440
the conservation community and the climate change community, we do
396
00:24:12,520 --> 00:24:15,722
have to be careful and make sure that we are doing it properly. And not just
397
00:24:15,742 --> 00:24:19,384
for the sake of putting it up on your letterhead, a blue carbon company
398
00:24:19,444 --> 00:24:22,947
or a company that supports blue carbon habitats, or even, you
399
00:24:22,987 --> 00:24:26,569
know, the UN or, you know, World Economic
400
00:24:26,609 --> 00:24:30,271
Forum or big organizations like that, international organizations
401
00:24:30,291 --> 00:24:34,515
and even even small to medium-sized to large NGOs
402
00:24:34,555 --> 00:24:37,718
that are getting into this type of practice, they have
403
00:24:37,738 --> 00:24:42,463
to be careful that these programs are real and these programs are establishing long-term
404
00:24:43,344 --> 00:24:46,848
blue carbon habitats, right? Because they're not just blue carbon habitats, they
405
00:24:46,928 --> 00:24:50,071
provide biodiversity, they provide security, these are
406
00:24:50,352 --> 00:24:53,514
some big to-do habitats. So those are sort
407
00:24:53,534 --> 00:24:57,375
of the three problems that people have, especially
408
00:24:57,415 --> 00:25:00,856
in Thailand, when it comes to putting
409
00:25:00,876 --> 00:25:04,277
this forward. The other thing, there's one more, sorry I forgot to mention,
410
00:25:05,058 --> 00:25:08,259
has to do with when you have private and public partnerships, you have
411
00:25:08,479 --> 00:25:11,940
private companies who are buying up swaths of
412
00:25:12,000 --> 00:25:15,242
land. They have ownership in some cases over that
413
00:25:15,302 --> 00:25:19,005
land. And so the question comes is, if they pay for
414
00:25:19,206 --> 00:25:22,648
planting mangroves in specific areas, does that area become
415
00:25:22,789 --> 00:25:25,931
theirs to own? Or does it go back to the people of
416
00:25:25,951 --> 00:25:29,134
Thailand? Does it go back to the local villages of the people who live there? Do they
417
00:25:29,194 --> 00:25:32,337
lose their rights on those lands? Obviously, that's not what is
418
00:25:32,697 --> 00:25:36,260
wanted. That's not the outcome that's wanted. So people want to retain the ownership
419
00:25:36,801 --> 00:25:40,084
rights. of their land and they don't want to have
420
00:25:40,124 --> 00:25:43,467
it go to a company where they can just do whatever they want with
421
00:25:43,547 --> 00:25:46,871
it and we know how companies are sometimes and many times and
422
00:25:47,051 --> 00:25:50,354
you know that's something that can be very concerning. So that's sort of
423
00:25:50,514 --> 00:25:53,898
the final thing that happens. Now overall, planting is
424
00:25:53,938 --> 00:25:57,880
great. Making sure that we have restoration location
425
00:25:57,920 --> 00:26:02,543
sites chosen for specific reasons of long-term restoration
426
00:26:02,763 --> 00:26:06,125
and establishment of mangrove areas will be key
427
00:26:06,465 --> 00:26:09,787
to ensuring that these mangroves stick around for a long period
428
00:26:09,807 --> 00:26:13,169
of time. You can have social economic benefits as well
429
00:26:13,189 --> 00:26:16,371
as environmental benefits. we can reduce climate change, we can
430
00:26:16,431 --> 00:26:20,453
have more blue carbon habitats along our coastline, naturalize
431
00:26:20,493 --> 00:26:24,015
our coastlines more, especially in Thailand, and
432
00:26:24,095 --> 00:26:27,176
just have a better planet after that. A lot of
433
00:26:27,216 --> 00:26:30,398
work still needs to be done, but there are great people that are doing the
434
00:26:30,458 --> 00:26:33,659
work in Thailand and across the world, and I think
435
00:26:33,960 --> 00:26:37,545
it's really great. Now, I know in my audience here, There
436
00:26:37,585 --> 00:26:41,088
are people who are in the business of restoration, whether it be corals,
437
00:26:41,208 --> 00:26:44,510
whether it be mangroves, whether it be seagrasses. I would love to hear your
438
