How a handful of fishing villages sparked a marine conservation revolution

  • 0:01 - 0:03
    I'm a marine biologist
  • 0:03 - 0:06
    here to talk to you
    about the crisis in our oceans,
  • 0:06 - 0:10
    but this time perhaps not
    with a message you've heard before,
  • 0:10 - 0:13
    because I want to tell you
    that if the survival of the oceans
  • 0:13 - 0:17
    depended only on people like me,
  • 0:17 - 0:20
    scientists trading in publications,
  • 0:20 - 0:23
    we'd be in even worse trouble than we are.
  • 0:23 - 0:25
    Because, as a scientist,
  • 0:25 - 0:27
    the most important things
    that I've learned
  • 0:27 - 0:31
    about keeping our oceans
    healthy and productive
  • 0:31 - 0:34
    have come not from academia
    but from fishermen and women
  • 0:34 - 0:37
    living in some of the poorest
    countries on earth.
  • 0:37 - 0:39
    I've learned that as a conservationist,
  • 0:39 - 0:43
    the most important question is not,
    "How do we keep people out?"
  • 0:44 - 0:49
    but rather, "How do we make sure
    that coastal people throughout the world
  • 0:49 - 0:50
    have enough to eat?"
  • 0:51 - 0:55
    Our oceans are every bit as critical
    to our own survival
  • 0:55 - 0:58
    as our atmosphere,
    our forests or our soils.
  • 0:58 - 1:01
    Their staggering productivity
    ranks fisheries with farming
  • 1:01 - 1:04
    as a mainstay of food production
  • 1:04 - 1:05
    for humanity.
  • 1:05 - 1:07
    Yet something's gone badly wrong.
  • 1:08 - 1:11
    We're accelerating
    into an extinction emergency,
  • 1:11 - 1:16
    one that my field has so far
    failed abysmally to tackle.
  • 1:16 - 1:20
    At its core is a very human
    and humanitarian crisis.
  • 1:21 - 1:24
    The most devastating blow
    we've so far dealt our oceans
  • 1:24 - 1:26
    is through overfishing.
  • 1:26 - 1:30
    Every year, we fish harder,
    deeper, further afield.
  • 1:30 - 1:33
    Every year, we chase ever fewer fish.
  • 1:33 - 1:37
    Yet the crisis of overfishing
    is a great paradox:
  • 1:37 - 1:41
    unnecessary, avoidable,
    and entirely reversible,
  • 1:41 - 1:46
    because fisheries are one of the most
    productive resources on the planet.
  • 1:46 - 1:49
    With the right strategies,
    we can reverse overfishing.
  • 1:50 - 1:53
    That we've not yet done so is, to my mind,
  • 1:53 - 1:56
    one of humanity's greatest failures.
  • 1:56 - 1:59
    Nowhere is this failure more apparent
  • 1:59 - 2:02
    than in the warm waters
    on either side of our equator.
  • 2:02 - 2:06
    Our tropics are home to most
    of the species in our ocean,
  • 2:06 - 2:10
    most of the people whose existence
    depends on our seas.
  • 2:10 - 2:14
    We call these coastal fishermen and women
    "small-scale fishers,"
  • 2:14 - 2:16
    but "small-scale" is a misnomer
  • 2:16 - 2:22
    for a fleet comprising over 90 percent
    of the world's fishermen and women.
  • 2:22 - 2:26
    Their fishing is generally
    more selective and sustainable
  • 2:26 - 2:28
    than the indiscriminate destruction
  • 2:28 - 2:31
    too often wrought
    by bigger industrial boats.
  • 2:31 - 2:35
    These coastal people have the most
    to gain from conservation,
  • 2:35 - 2:36
    because for many of them,
  • 2:36 - 2:41
    fishing is all that keeps them
    from poverty, hunger or forced migration,
  • 2:41 - 2:45
    in countries where the state
    is often unable to help.
  • 2:45 - 2:48
    We know that the outlook is grim:
  • 2:48 - 2:51
    stocks collapsing
    on the front lines of climate change,
  • 2:51 - 2:55
    warming seas, dying reefs,
    catastrophic storms,
  • 2:55 - 2:57
    trawlers, factory fleets,
  • 2:57 - 3:02
    rapacious ships from richer countries
    taking more than their share.
  • 3:02 - 3:05
    Extreme vulnerability is the new normal.
  • 3:06 - 3:10
    I first landed on the island
    of Madagascar two decades ago,
  • 3:10 - 3:13
    on a mission to document
    its marine natural history.
  • 3:13 - 3:16
    I was mesmerized
    by the coral reefs I explored,
  • 3:16 - 3:18
    and certain I knew how to protect them,
  • 3:18 - 3:21
    because science provided all the answers:
  • 3:21 - 3:24
    close areas of the reef permanently.
  • 3:24 - 3:27
    Coastal fishers
    simply needed to fish less.
  • 3:27 - 3:30
    I approached elders here
    in the village of Andavadoaka
  • 3:30 - 3:32
    and recommended that they close off
  • 3:32 - 3:36
    the healthiest and most diverse
    coral reefs to all forms of fishing
  • 3:36 - 3:38
    to form a refuge to help stocks recover,
  • 3:38 - 3:43
    because, as the science tells us,
    after five or so years,
  • 3:43 - 3:47
    fish populations inside those refuges
    would be much bigger,
  • 3:47 - 3:49
    replenishing the fished areas outside,
  • 3:49 - 3:52
    making everybody better off.
  • 3:52 - 3:55
    That conversation didn't go so well.
  • 3:55 - 3:56
    (Laughter)
  • 3:56 - 3:59
    Three-quarters of Madagascar's
    27 million people
  • 3:59 - 4:01
    live on less than two dollars a day.
  • 4:02 - 4:04
    My earnest appeal to fish less
    took no account
  • 4:04 - 4:06
    of what that might actually mean
  • 4:06 - 4:09
    for people who depend
    on fishing for survival.
  • 4:09 - 4:11
    It was just another squeeze from outside,
  • 4:11 - 4:14
    a restriction rather than a solution.
  • 4:14 - 4:19
    What does protecting a long list
    of Latin species names mean to [unclear],
  • 4:19 - 4:21
    a woman from Andavadoaka
    who fishes every day
  • 4:21 - 4:23
    to put food on the table
  • 4:23 - 4:25
    and send her grandchildren to school?
  • 4:26 - 4:30
    That initial rejection taught me
    that conservation is, at its core,
  • 4:31 - 4:35
    a journey in listening deeply,
  • 4:35 - 4:38
    to understand the pressures
    and realities that communities face
  • 4:38 - 4:40
    through their dependence on nature.
  • 4:40 - 4:44
    This idea became
    the founding principle for my work
  • 4:44 - 4:47
    and grew into an organization
    that brought a new approach
  • 4:47 - 4:48
    to ocean conservation
  • 4:48 - 4:52
    by working to rebuild fisheries
    with coastal communities.
  • 4:53 - 4:57
    Then, as now, the work
    started by listening,
  • 4:57 - 4:59
    and what we learned astonished us.
  • 5:00 - 5:01
    Back in the dry south of Madagascar,
  • 5:01 - 5:05
    we learned that one species
    was immensely important for villagers:
  • 5:05 - 5:07
    this remarkable octopus.
  • 5:07 - 5:11
    We learned that soaring demand
    was depleting an economic lifeline.
  • 5:11 - 5:15
    But we also learned that this animal
    grows astonishingly fast,
  • 5:15 - 5:18
    doubling in weight
    every one or two months.
  • 5:18 - 5:22
    We reasoned that protecting
    just a small area of fishing ground
  • 5:22 - 5:23
    for just a few months
  • 5:23 - 5:27
    might lead to dramatic
    increases in catches,
  • 5:27 - 5:30
    enough to make a difference
    to this community's bottom line
  • 5:30 - 5:33
    in a time frame that might
    just be acceptable.
  • 5:34 - 5:35
    The community thought so too,
  • 5:35 - 5:40
    opting to close a small area of reef
    to octopus fishing temporarily,
  • 5:40 - 5:42
    using a customary social code,
  • 5:42 - 5:46
    invoking blessings from the ancestors
    to prevent poaching.
  • 5:47 - 5:50
    When that reef reopened
    to fishing six, months later,
  • 5:50 - 5:53
    none of us were prepared
    for what happened next.
  • 5:54 - 5:56
    Catches soared,
  • 5:56 - 5:59
    with men and women landing
    more and bigger octopus
  • 5:59 - 6:01
    than anyone had seen for years.
  • 6:01 - 6:04
    Neighboring villages saw the fishing boom
  • 6:04 - 6:05
    and drew up their own closures,
  • 6:05 - 6:09
    spreading the model virally
    along hundreds of miles of coastline.
  • 6:09 - 6:11
    When we ran the numbers,
  • 6:11 - 6:14
    we saw that these communities,
    among the poorest on earth,
  • 6:14 - 6:19
    had found a way to double their money
    in a matter of months, by fishing less.
  • 6:20 - 6:21
    Imagine a savings account
  • 6:21 - 6:24
    from which you withdraw
    half your balance every year
  • 6:24 - 6:25
    and your savings keep growing.
  • 6:25 - 6:29
    There is no investment
    opportunity on earth
  • 6:29 - 6:32
    that can reliably deliver
    what fisheries can.
  • 6:32 - 6:36
    But the real magic went beyond profit,
  • 6:36 - 6:40
    because a far deeper transformation
    was happening in these communities.
  • 6:40 - 6:42
    Spurred on by rising catches,
  • 6:42 - 6:47
    leaders from Andavadoaka joined force
    with two dozen neighboring communities
  • 6:47 - 6:52
    to establish a vast conservation area
    along dozens of miles of coastline.
  • 6:53 - 6:56
    They outlawed fishing with poison
    and mosquito nets
  • 6:56 - 6:58
    and set aside permanent refuges
  • 6:58 - 7:00
    around threatened
    coral reefs and mangroves,
  • 7:01 - 7:03
    including, to my astonishment,
  • 7:03 - 7:07
    those same sights that I'd flagged
    just two years earlier
  • 7:07 - 7:11
    when my evangelism for marine protection
    was so roundly rejected.
  • 7:11 - 7:14
    They created a community-led
    protected area,
  • 7:14 - 7:18
    a democratic system
    for local marine governance
  • 7:18 - 7:21
    that was totally unimaginable
    just a few years earlier.
  • 7:22 - 7:23
    And they didn't stop there:
  • 7:24 - 7:27
    within five years, they'd secured
    legal rights from the state
  • 7:27 - 7:30
    to manage over 200 square miles of ocean,
  • 7:30 - 7:35
    eliminating destructive
    industrial trawlers from the waters.
  • 7:35 - 7:38
    Ten years on, we're seeing
    recovery of those critical reefs
  • 7:38 - 7:40
    within those refuges.
  • 7:40 - 7:43
    Communities are petitioning
    for greater recognition
  • 7:43 - 7:44
    of the right to fish
  • 7:44 - 7:47
    and fairer prices
    that reward sustainability.
  • 7:48 - 7:51
    But all that is just
    the beginning of the story,
  • 7:51 - 7:55
    because this handful
    of fishing villages taking action
  • 7:55 - 7:58
    has sparked a marine
    conservation revolution
  • 7:58 - 8:00
    that has spread over thousands of miles,
  • 8:00 - 8:03
    impacting hundreds of thousands of people.
  • 8:03 - 8:07
    Today in Madagascar, hundreds of sites
    are managed by communities
  • 8:07 - 8:10
    applying this human rights-based
    approach to conservation
  • 8:10 - 8:13
    to all kinds of fisheries,
    from mud crabs to mackerel.
  • 8:13 - 8:18
    The model has crossed borders
    through East Africa and the Indian Ocean
  • 8:18 - 8:20
    and is now island-hopping
    into Southeast Asia.
  • 8:20 - 8:25
    From Tanzania to Timor-Leste,
    from India to Indonesia,
  • 8:25 - 8:27
    we're seeing the same story unfold:
  • 8:29 - 8:31
    that when we design it right,
  • 8:31 - 8:35
    marine conservation reaps dividends
    that go far beyond protecting nature,
  • 8:35 - 8:37
    improving catches
  • 8:37 - 8:41
    and driving waves of social change
    along entire coastlines,
  • 8:41 - 8:44
    strengthening confidence, cooperation,
  • 8:44 - 8:48
    and the resilience of communities
    to face the injustice of poverty
  • 8:48 - 8:50
    and climate change.
  • 8:51 - 8:54
    I've been privileged to spend my career
  • 8:54 - 8:59
    catalyzing and connecting these movements
    throughout the tropics,
  • 8:59 - 9:01
    and I've learned that as conservationists,
  • 9:01 - 9:03
    our goal must be to win at scale,
  • 9:03 - 9:05
    not just to lose more slowly.
  • 9:06 - 9:09
    We need to step up
    to this global opportunity
  • 9:09 - 9:11
    to rebuild fisheries:
  • 9:11 - 9:14
    with field workers to stand
    with communities
  • 9:14 - 9:19
    and connect them, to support them,
    to act and learn from one another;
  • 9:19 - 9:22
    with governments and lawyers
    standing with communities
  • 9:22 - 9:25
    to secure their rights
    to manage their fisheries;
  • 9:25 - 9:28
    prioritizing local food and job security
  • 9:28 - 9:32
    above all competing interests
    in the ocean economy;
  • 9:32 - 9:37
    ending subsidies for grotesquely
    overcapitalized industrial fleets
  • 9:37 - 9:39
    and keeping those industrial
    and foreign vessels
  • 9:39 - 9:42
    out of coastal waters.
  • 9:42 - 9:43
    We need agile data systems
  • 9:43 - 9:46
    that put science
    in the hands of communities
  • 9:46 - 9:51
    to optimize conservation
    to the target species or habitat.
  • 9:51 - 9:56
    We need development agencies,
    donors, and the conservation establishment
  • 9:56 - 9:59
    to raise their ambition
    to the scale of investment
  • 9:59 - 10:02
    urgently required to deliver this vision.
  • 10:03 - 10:04
    And to get there,
  • 10:04 - 10:07
    we all need to reimagine
    marine conservation
  • 10:08 - 10:11
    as a narrative of abundance
    and empowerment,
  • 10:11 - 10:13
    not of austerity and alienation;
  • 10:13 - 10:18
    a movement guided by the people who depend
    on healthy seas for their survival,
  • 10:18 - 10:22
    not by abstract scientific values.
  • 10:23 - 10:27
    Of course, fixing overfishing
    is just one step to fixing our oceans.
  • 10:27 - 10:33
    The horrors of warming,
    acidification and pollution grow each day.
  • 10:33 - 10:34
    But it's a big step.
  • 10:34 - 10:37
    It's one we can take today,
  • 10:37 - 10:39
    and it's one that will give
    a much-needed boost
  • 10:39 - 10:41
    to those exploring scalable solutions
  • 10:41 - 10:44
    to other dimensions
    of our ocean emergency.
  • 10:44 - 10:47
    Our success propels theirs.
  • 10:47 - 10:50
    If we throw up our hands in despair,
  • 10:50 - 10:51
    it's game over.
  • 10:51 - 10:55
    We solve these challenges
    by taking them on one by one.
  • 10:56 - 11:00
    Our overwhelming dependence
    on our ocean is the solution
  • 11:00 - 11:04
    that has been hiding in plain sight,
  • 11:04 - 11:07
    because there's nothing small
    about small-scale fishers.
  • 11:07 - 11:11
    They're a hundred million strong
    and provide nutrition to billions.
  • 11:11 - 11:15
    It's this army of everyday
    conservationists
  • 11:15 - 11:16
    who have the most at stake.
  • 11:16 - 11:20
    Only they have the knowledge
    and global reach needed
  • 11:20 - 11:23
    to reshape our relationship
    with our oceans.
  • 11:24 - 11:29
    Helping them achieve this
    is the most powerful thing we can do
  • 11:29 - 11:31
    to keep our oceans alive.
  • 11:31 - 11:32
    Thank you.
  • 11:32 - 11:36
    (Applause)
