The European Union has protected lands
of more than 26% as of 2023. They are doing this so that they can have
a variety of different elements impacted,
00:00:14
like restoring vegetation cover and also
improving biodiversity. But how do those policies work?
00:00:22
Are they as effective as they can be? Pleasure to be joined by Arthur Van
Benthem, who is a Professor at the Wharton
00:00:28
School of Business Ethics and Public
Policy. He and a group of his
colleagues have been working on
00:00:35
focusing on these policies
and he joins us right now. Arthur, great to catch up with you.
How are you, sir?
00:00:40
I'm doing fine.
Thank you for having me. Thank you. So I guess let's start
with the research itself and why it's
00:00:47
important to truly understand
the impact of these policies. Yeah, I think nature is in a pretty dire
state in many continents.
00:01:01
So there is this push globally to protect
30% of the Earth's lands and waters in an
00:01:08
effort to fight back against biodiversity
degradation. So from that perspective,
it's truly important
00:01:15
to see our countries
reaching those targets. And if they're reaching them, are they
actually effective at restoring nature?
00:01:22
How do you gauge then the effectiveness of
these policies? How does that occur? Well, we focus specifically on the
European Union, which is the continent
00:01:34
that is closest to reaching that 30%
target by 2030. They're actually getting there,
27 percent at the moment.
00:01:44
And the way to do this is using
satellite data. So Europe is adding more and more protected
areas in the various countries every year.
00:01:54
And what we track as researchers is the
greenest of those lands. Of course, you don't expect a lush forest
the year after you protect a piece of
00:02:04
grassland, but slowly over time,
you expect to see forest regrowth and maybe people moving out in the areas that
are protected.
00:02:14
So we use a lot of satellite data, nightlights,
greenness, those kinds of measures.
00:02:20
And I noticed that in the paper you talk
about, there are some areas that seemingly
00:02:26
have done a very good job in terms of
recovery, and other areas that have not. How then are you able to better understand
what's going on in these different areas
00:02:36
and maybe what has gone right and what has
not? Yeah, that's, of course, the key question
in our research, right?
00:02:44
So actually the reason we started studying
Europe is we read a couple of years ago,
00:02:49
me and my co-authors,
that Europe is a fair bit greener today than
it was a century ago.
00:02:54
So it's sort of across the continent. There's more forests, for example.
00:02:58
We've also seen that more land has become
protected. But what we tend to see in a lot of areas
in Europe is, you know, the comparison we
00:03:07
need to make is, is
it really the protection that led to that increase
in vegetation cover?
00:03:13
Or is that something that would have
happened anyway, perhaps as urbanization happens and agricultural imports are
increasing and less is grown in Europe itself?
00:03:24
There could be other explanations. What we find is that there's a lot of
areas in Europe that are getting greener.
00:03:30
It just doesn't seem to be the protection
that triggers it. So that suggests that a lot of protection
is happening in areas that were already on
00:03:38
a path of greening. So then what is happening that is leading
to this higher level of protection if it's
00:03:47
not the policy that's kind of having the
impact? Yeah, so that's a question that there's
lots of speculation and thoughts about.
00:03:56
I haven't seen the definitive answer to
that. I will add, this is for parts of Europe.
00:04:00
So about half of it is seeing these
improvements. Nature is also under tremendous pressure
in other parts of Europe.
00:04:09
But the question why in the Baltics and,
for example, in northern Europe and southeast Europe, that that greening trend
is happening in general,
00:04:18
people have attributed to various things,
including sort of a change in the economy
00:04:22
over the last several decades away from
agriculture and industry towards services.
00:04:28
People have thought about climate change
even as explanations, but I don't think
00:04:33
the answer to that has been proven in any
definitive way. And if I read it correctly, I believe you
mentioned in the paper that you also have
00:04:40
to take into effect what the, for lack of
a better term, the federal government in
00:04:47
each of these countries is doing from a
policy perspective to in some cases what
00:04:52
local governments are doing on this topic
as well. Yes, I need to explain to you a little bit
about— so, what does protection mean?
00:04:59
So protection can mean lots of different
things. Like you may think about the Grand Canyon,
which is very strictly protected,
00:05:07
and there's some of that in Europe. But there's lots of different categories.
00:05:11
Anything from a big national park to a
local county park is in my data set. Okay.
00:05:19
Now, the EU federally
dictates to the member states that they should reach
that 30% slowly over time.
00:05:28
Then think of, say, a country like France
is going to outsource a lot of that to its
00:05:32
local government, and they are the ones
that then have to have the stakeholder meetings to get people together about, can
they protect some new area?
00:05:41
And what tends to happen in a lot of
European countries is that's a fairly consultative process, right?
00:05:46
You need the local
communities, the farmers, the scientists, the water management
bodies, everyone to agree.
00:05:53
And the more people that need to agree on
something, in practice, the weaker, of course, the consensus or the agreement
becomes.
00:06:01
So we tend to see a lot of protection on
paper, but then those tend to be fairly
00:06:07
minimally protected
areas, say agricultural areas where there's some
restriction on economic activity.
00:06:14
But this is far from a pristine nature
that's regrowing or protected. So you bring up something I wanted to ask
you anyway, is that, how then do these
00:06:25
countries go about kind of marking off
what are going to be those protected lands
00:06:31
in comparison to areas that
they may want to develop for business, for the economy
of their country as well?
00:06:39
Yeah, you're getting
at the reason why this is a complicated
statistical problem, right?
00:06:45
There's a lot of selection. It's not random which areas are protected. So countries would prefer, if they can,
to protect areas where the economic cost
00:06:56
of reaching that 30% target is relatively
minor. So what can you do? Well, you can do two things.
00:07:03
Either you look at far away, remote areas
that are, say, forested or natural, and you say— you put a stamp on it,
right?
00:07:12
And say, like, "Oh, this is now strictly
protected." There's a lot of that has been happening
in Northern Europe, for example,
00:07:18
in Scandinavia, which is, you know,
useful on paper, but not particularly changing the course of nature in those
countries.
00:07:26
Or you say, I'm protecting lots of land
near cities, but then I am going to assign
00:07:31
it a fairly weak protection
status that doesn't interfere too much with
my other development plans.
00:07:36
And I think, in a nutshell, that is really
sort of the reason why we across four
00:07:41
decades, across all European countries,
do not detect a very impactful policy. Can you start then to better understand,
having done this research, the level of
00:07:56
quality of work being done by the European
Union in terms of protecting these lands?
00:08:02
Well, let me put out first that we point
out that this particular policy that the
00:08:09
European Union has been pushing,
which is really laser focused on achieving that quantity target, that 30%, that that
might have been a bit counterproductive.
00:08:21
I guess the EU has been focused too much,
and we need to reach the 30% without asking perhaps the question, is that 30%
having a large effect?
00:08:31
Is it changing what would have happened
otherwise? That said, I think the EU has been very,
very thoughtful in its environmental
00:08:38
policy in general, including its policies
to protect nature. There's a different policy called the
Nature Restoration Law, which isn't
00:08:47
focused as much on protecting new lands,
but to improve the quality, the deteriorating quality of the existing
protected areas.
00:08:56
And that might be much more impactful. And that's, in fact, another angle I'd want
to go into in future research.
00:09:03
So I applaud the EU for being thoughtful
in general, but we're hoping to point out
00:09:08
that just a percentage alone is not enough
to have real impact. Right, exactly. And then the other question, from my
knowledge, is when we're talking about a
00:09:18
30% piece of territory within,
are we talking within each country, or are we talking about the European Union
as a whole?
00:09:27
Like, you know, the levels
may vary from country to country, but it's
30% on scope.
00:09:34
Yeah, the EU passes down to 30% to each
individual country. It is, of course, much easier to meet that
for a country like Sweden that has lots of
00:09:43
areas with low population
density and lots of forest, than for my home
country, the Netherlands.
00:09:49
So when you look at the map, it's kind of
interesting. You see these large connected contiguous
areas in some countries.
00:09:57
And then in a densely populated country
like mine, you will see a patchwork of tiny areas because they're really
scrambling to find the 30%.
00:10:06
What then does this research, and does it,
kind of open the door to understand how
00:10:14
the United States is looking at having
protected lands? Right. So our paper at Europe
has studied a policy that— it's
00:10:25
the flagship policy for
protection, or one of those two. And then we're showing, unfortunately,
that it hasn't worked too well.
00:10:33
So that has somewhat of a limitation that
it hasn't proven that a policy that we
00:10:39
could import here into the United States. I do think that what's happening here in
the US is very different.
00:10:48
The current federal administration is
actively taking away nature protections. Think about the waters of the US,
the Endangered Species Act.
00:10:56
And I think in general, we see both in the
US and in Europe, a pretty alarming speed
00:11:03
of deterioration of our natural
ecosystems. And I think that this approach to trade
a quick economic gain here in the US by
00:11:11
weakening those standards is unbelievably
short-sighted. And I really hope that everyone can agree,
whether you're Republican, Democrat,
00:11:18
or Independent, that
we all benefit from the beauty and the economic
value of our natural land.
00:11:24
So I think it's more— in
the US, it's about, you know, let's at least stop
weakening those standards.
00:11:31
And I hope we can get to a
point where we can discuss about how do we tighten
them in a more effective way?
00:11:37
