Loving the Green that
Feeds you

Dr. Gary Martin, Regional Co-ordinator of People and
Plants Southeast Asia, was very blunt and had nothing to
apologise for being so.
He said: "Without plants on earth, we wouldn't be
on earth."
It's a hard reminder to people to remember everything
they eat and breathe originate from plants.
On the other hand, he pointed out: The world is
depending on just about 100 species of plants to survive
now. That makes up 90 percent of the world's well
being."
The problem is cities now house probably the majority
of the world's population who falsely assume they are
less dependant on plants.
So the big question is how to resolve a future crunch
when ever burgeoning world population exert even greater
pressure on an ever dwindling plant stock.
"We know that in addition to the 100 species that
the world depends on for its well being, there are
probably another 1,000 species which are marketed locally
and regionally in regional commerce, some of which are
cultivated but a lot of them are coming straight out from
the forest which means as demand goes up, these plants
become scarcer and scarcer because we are harvesting them
heavily," he said.
"Products like medicinal plants, for example, are
being harvested at levels beyond the trees and plants to
produce," Dr. Martin said.
"Those are the things which have been
commercialised, he said.
"But when you start getting into the communities
who live around the forests, you realise there are a lot
of things which they never buy or
sell."
-
"They go out into the forest harvesting medicinal
plants for home use and harvesting edible
plants."
Dr. Martin went on: Even at Kg. Manggis which we
visited, you find people are going into the forest to
collect vegetables such as bananas, ginger, edible ferns
plus many others.
"In the past, when people made a lot of craft
objects like baskets, dye fabrics. So you have rattan,
dye plants and timber all these things came from the
forests also."
Asked what are the critical issues in this question of
people and plants, Dr. Martin said: "Whenever I am
teaching or do a project like this, I think of plants in
a pyramid. The top of that pyramid comprise the 100
plants I mentioned earlier on and they say that's the 100
resources out there and that make up most of how we live!
It's a scary situation when you think that overtime,
civilization started off using lots and lots of
plants, he pointed out.
"Now, as a world civilization, we have decided
that the way to evolve is by actually using very few
resources -100 plants, mostly food plants. That's bad
enough, not a good strategy."
We should have as many options open, instead of
narrowing your options."
"But even worse is that in that top of the
pyramid, we are decreasing diversity," he
said.
"For example, during the Green Revolution, we
bred certain varieties of rice and corn that were growing
very well with things like chemical fertilizers,
herbicides and insecticides. So, they did extremely well
for certain years, for those who had the money to buy
these chemical inputs," Martin said.
"But what are the down side? Some years they
didn't do so well. Even if they did, we all know what
herbicides, pesticides and chemical fertilizers do to the
environment."
"The alternative is to maintain local varieties.
Over time, communities have bred hundreds and thousands
of varieties of everything," he pointed out.
"That's why you have different types of bananas,
different types of rice. If you just go out to a Dusun or
Murut community here, you see dozens and they all have
their different characteristics and they all have better
tasting than when you get Uncle..."
It's good rice."
"But overtime, what we are doing is just
narrowing down not just the number of species we use but
the genetic diversity of those cultivated
species.
"That's the top of the pyramid. A big critical
issue there is instead of decreasing diversity, let's
expand it by recovering local varieties and selecting the
seeds, cultivating them in the communities, sharing that
seed with other communities," he said.
"That's why in this course (People and Plants in
Southeast Asia Certificate Training Course in Applied
Ethnobotany at Kinabalu Park) we have brought along a
couple in Australia, Judy and Michel Fenton and they are
part of this thing called The Seed Savers
Network."
"What they do is encourage people to do that -
don't let go that tomato that grandma had been growing
for the last 60 years. And it's the seed. We'll send that
seed to any body who asks. And now those people are
sending cut cantaloupe (small round ripped rock melon
first grown
grown near Rome in Europe) that grandpa had been growing
in his backyard in Brisbane over the last 50 years. And
instead of leaving with grandpa, its seeds are now all
over Australia," he said.
"And it's better than a hybrid type of melon or a
cantaloupe you buy in the Store. Why lose all those
things. Why throw away those big things which had been
developed over time?" he asked.
"As I go down the pyramid, the next layer is what
we call the secondary pool of resources. This pool
contains roughly about 1,000 species of the
commercialised species on a local or regional
level." "I have given a couple of examples,
things like rattan, damal resin which was formerly
important, and daharu resin which is still very
important."
"We certainly recognise the importance of those
plants to the local economy. But the big challenge there
is making sure that we don't put those plants out of
business by over harvesting," Dr. Martin said.
"Some of them are cultivated. In that case, we
don't have a problem. Let's take an example of vanilla.
Vanilla orchids were wild. In Mexico where they
originated, they are still wild vanilla orchids being
harvested," he said.
"Now, if vanilla had not become a cultivated
crop, we may be in big trouble in terms of wiping out
that particular species," he illus-trated.
Look at what we are collecting? Their fruits. If so,
where are the new plants going to come from?"
So, for each of these species in the secondary pool,
you have to look at their biological characteristics,
what are you harvesting. You have also to look at the
social characteristic the demand in the world
market and you go species by species."
You take something like vanilla and you say,
well, not a particular problem - it's been brought into
cultivation. It's not one of those 100 most important
plants."
"But the market for, vanilla will stay.
Communities' can grow it on a local scale. Actually, it
almost needs to be grown in forest. So, that's when it
gets a seal of approval from people interested in
community development and conservation - to be grown by
communities, to be marketed by communities. There are
projects like this including Mexico."
However, he pointed out: "There are certain
dangers involved in any of these secondary pool resources
. Having to deal with ups and downs in the market. Right
now, Vanilla has become the thing. So, every body is
running around telling communities to grow vanilla. But
what happens when you do that on a world
scale?"
"The price drop. You have seen it with cocoa,
palm oil, coffee."
"That's one of the challenges too. Putting for
things communities can do with these products that can
support village level local economies but on a regular
and continuous basis."
"To point out a couple of issues here, that
secondary pool is really important to local economy. It's
really vulnerable to over harvesting if you don't pay
attention to the basic biological and cultural
characteristics of that plant."
"And third, it is very vulnerable to the
moodiness of the market - the ups and downs that you
get."
"So, whenever we grab get a species, we have to
really analyse things very carefully and say, well,
what's going on with this particular tree. Lets look at
the gaharu tree. How do you harvest it? Just cut down the
tree very destructive harvesting. How many are
there? One per hectre in places like the Kinabalu Park,
not very much. What is the market? What is the demand?
Enormous - thousands of dollars per kilo of high grade
gaharu, part of it goes off to an Asian market, the other
part goes off to an Middle Eastern market and that's why
we get a lot of destructive, illegal harvesting. That's a
classic example that one that doesn't win a seal of
approval, definitely not a sustainable return, definitely
not benefiting the communities," he said.
"So, that's what we call going down the pyramid. The
Primary pool consist of mainly food and some industrial
materials. In the secondary pool, there is a big
diversity of things - medicine, timber, wild fruits and
in Borneo, there is certainly a very diverse range of
products people are using."
In the Tertiary Pool, we estimate there are
about 50,000 plants," said Dr. Martin.
These include a whole range of things you can
imagine. But in general, those in the tertiary pool are
harvested from the forest or in areas which are not
strictly cultivated," he said.
"But before manufactured products, everything
came from them - clothing, construction materials, edible
plants, medicinal plants etc."
"If you visit the New Zealand Museum of Economic
Plants and Royal Botanic Garden, Kew, you would be amazed
what there is all over the world - clothes made out of
marazi bark, resins for medicine, fruits used for food,
an incredible range of things," Dr, Martin
marvelled.
" But even after a hundred years of documenting
useful plants in ethnobotany, we still don't have a data
base of all those useful plants around the world,"
he pointed out.
"On top of that all, there is a Reserve Pool of
200,000 to 220,000 species that currently have no
recorded use," Dr. Martin said.
"It's incredible. These plants are important too
for other reasons, such as watershed protection, for
maintaining ecological, processes."
They are important for ecotourism. All the plants in
the Kinabalu Park people come to see them, not just the
rafflesia or nepenthes which are very popular, but the
general look of the forest provided by plants. That's the
sort of Reserve Pool that eventually may be used as we
look for new medicine and plants, in a field called
bioprospection biologically for new products."
"Those are all potential plants that could be
useful."
"In a nutshell, that the way of summing up the
utility of plants to people," Dr Martin
explained.
