1 99:59:59,999 --> 99:59:59,999 I'm a marine biologist 2 99:59:59,999 --> 99:59:59,999 here to talk to you about the crisis in our oceans, 3 99:59:59,999 --> 99:59:59,999 but this time perhaps not with a message you've heard before, 4 99:59:59,999 --> 99:59:59,999 because I want to tell you that if the survival of the oceans 5 99:59:59,999 --> 99:59:59,999 depended only on people like me, 6 99:59:59,999 --> 99:59:59,999 scientists trading in publications, 7 99:59:59,999 --> 99:59:59,999 we'd be in even worse trouble than we are. 8 99:59:59,999 --> 99:59:59,999 Because, as a scientist, 9 99:59:59,999 --> 99:59:59,999 the most important things that I've learned 10 99:59:59,999 --> 99:59:59,999 about keeping our oceans healthy and productive 11 99:59:59,999 --> 99:59:59,999 have come not from academia but from fishermen and women 12 99:59:59,999 --> 99:59:59,999 living in some of the poorest countries on Earth. 13 99:59:59,999 --> 99:59:59,999 I've learned that as a conservationist, 14 99:59:59,999 --> 99:59:59,999 the most important question is not, "how do we keep people out?" 15 99:59:59,999 --> 99:59:59,999 but rather, "how do we make sure that coastal people throughout the world 16 99:59:59,999 --> 99:59:59,999 have enough to eat?" 17 99:59:59,999 --> 99:59:59,999 Our oceans are every bit as critical to our own survival 18 99:59:59,999 --> 99:59:59,999 as our atmosphere, our forests or our soils. 19 99:59:59,999 --> 99:59:59,999 Their staggering productivity ranks fisheries with farming 20 99:59:59,999 --> 99:59:59,999 as a mainstay of food production 21 99:59:59,999 --> 99:59:59,999 for humanity. 22 99:59:59,999 --> 99:59:59,999 Yet, something's gone badly wrong. 23 99:59:59,999 --> 99:59:59,999 We're accelerating into an extinction emergency, 24 99:59:59,999 --> 99:59:59,999 one that my field has so far failed abysmally to tackle. 25 99:59:59,999 --> 99:59:59,999 At its core is a very human and humanitarian crisis. 26 99:59:59,999 --> 99:59:59,999 The most devastating blow we've so far dealt our oceans 27 99:59:59,999 --> 99:59:59,999 is through overfishing. 28 99:59:59,999 --> 99:59:59,999 Every year, we fish harder, 29 99:59:59,999 --> 99:59:59,999 deeper, further afield. 30 99:59:59,999 --> 99:59:59,999 Every year, we chase ever fewer fish. 31 99:59:59,999 --> 99:59:59,999 Yet, the crisis of overfishing is a great paradox: 32 99:59:59,999 --> 99:59:59,999 unnecessary, avoidable, 33 99:59:59,999 --> 99:59:59,999 and entirely reversible, 34 99:59:59,999 --> 99:59:59,999 because fisheries are one of the most productive resources on the planet. 35 99:59:59,999 --> 99:59:59,999 With the right strategies, 36 99:59:59,999 --> 99:59:59,999 we can reverse overfishing. 37 99:59:59,999 --> 99:59:59,999 That we've not yet done so is, to my mind, 38 99:59:59,999 --> 99:59:59,999 one of humanity's greatest failures. 39 99:59:59,999 --> 99:59:59,999 Nowhere is this failure more apparent 40 99:59:59,999 --> 99:59:59,999 than in the warm waters on either side of our equator. 41 99:59:59,999 --> 99:59:59,999 Our tropics are home to most of the species in our ocean, 42 99:59:59,999 --> 99:59:59,999 most of the people whose existence depends on our seas. 43 99:59:59,999 --> 99:59:59,999 We call these coastal fishermen and women "small-scale fishers," 44 99:59:59,999 --> 99:59:59,999 but small-scale is a misnomer 45 99:59:59,999 --> 99:59:59,999 for a fleet comprising over 90 percent of the world's fishermen and women. 46 99:59:59,999 --> 99:59:59,999 Their fishing is generally more selective and sustainable 47 99:59:59,999 --> 99:59:59,999 than the indiscriminate destruction 48 99:59:59,999 --> 99:59:59,999 too often wrought by bigger industrial boats. 49 99:59:59,999 --> 99:59:59,999 These coastal people have the most to gain from conservation, 50 99:59:59,999 --> 99:59:59,999 because for many of them, 51 99:59:59,999 --> 99:59:59,999 fishing is all that keeps them from poverty, hunger or forced migration 52 99:59:59,999 --> 99:59:59,999 in countries where the state is often unable to help. 53 99:59:59,999 --> 99:59:59,999 We know that the outlook is grim: 54 99:59:59,999 --> 99:59:59,999 stocks collapsing 55 99:59:59,999 --> 99:59:59,999 on the front lines of climate change, 56 99:59:59,999 --> 99:59:59,999 warming seas, dying reefs, catastrophic storms, 57 99:59:59,999 --> 99:59:59,999 trawlers, factory fleets, 58 99:59:59,999 --> 99:59:59,999 rapacious ships from richer countries taking more than their share. 59 99:59:59,999 --> 99:59:59,999 Extreme vulnerability is the new normal. 60 99:59:59,999 --> 99:59:59,999 I first landed on the island of Madagascar two decades ago 61 99:59:59,999 --> 99:59:59,999 on a mission to document its marine natural history. 62 99:59:59,999 --> 99:59:59,999 I was mesmerized by the coral reefs I explored, 63 99:59:59,999 --> 99:59:59,999 and certain I knew how to protect them, 64 99:59:59,999 --> 99:59:59,999 because science provided all the answers: 65 99:59:59,999 --> 99:59:59,999 close areas of the reef permanently. 66 99:59:59,999 --> 99:59:59,999 Coastal fishers simply needed to fish less. 67 99:59:59,999 --> 99:59:59,999 I approached elders here in the village of Andavadoaka 68 99:59:59,999 --> 99:59:59,999 and recommended that they close off 69 99:59:59,999 --> 99:59:59,999 the healthiest and most diverse coral reefs to all forms of fishing 70 99:59:59,999 --> 99:59:59,999 to form a refuge to help stocks recover, 71 99:59:59,999 --> 99:59:59,999 because, as the science tells us, after five or so years, 72 99:59:59,999 --> 99:59:59,999 fish populations inside those refuges would be much bigger, 73 99:59:59,999 --> 99:59:59,999 replenishing the fished areas outside, 74 99:59:59,999 --> 99:59:59,999 making everybody better off. 75 99:59:59,999 --> 99:59:59,999 That conversation didn't go so well. 76 99:59:59,999 --> 99:59:59,999 Three quarters of Madagascar's 27 million people 77 99:59:59,999 --> 99:59:59,999 live on less than two dollars a day. 78 99:59:59,999 --> 99:59:59,999 My earnest appeal to fish less took no account 79 99:59:59,999 --> 99:59:59,999 of what that might actually mean 80 99:59:59,999 --> 99:59:59,999 for people who depend on fishing for survival. 81 99:59:59,999 --> 99:59:59,999 It was just another squeeze from outside, 82 99:59:59,999 --> 99:59:59,999 a restriction rather than a solution. 83 99:59:59,999 --> 99:59:59,999 What does protecting a long list of Latin species names mean to ??, 84 99:59:59,999 --> 99:59:59,999 a woman from Andavadoaka who fishes every day 85 99:59:59,999 --> 99:59:59,999 to put food on the table 86 99:59:59,999 --> 99:59:59,999 and send her grandchildren to school? 87 99:59:59,999 --> 99:59:59,999 That initial rejection taught me that conservation is, at its core, 88 99:59:59,999 --> 99:59:59,999 a journey in listening deeply 89 99:59:59,999 --> 99:59:59,999 to understand the pressures and realities that communities face 90 99:59:59,999 --> 99:59:59,999 through their dependence on nature. 91 99:59:59,999 --> 99:59:59,999 This idea became the founding principle for my work 92 99:59:59,999 --> 99:59:59,999 and grew into an organization that brought a new approach 93 99:59:59,999 --> 99:59:59,999 to ocean conservation 94 99:59:59,999 --> 99:59:59,999 by working to rebuild fisheries with coastal communities. 95 99:59:59,999 --> 99:59:59,999 Then, as now, the work started by listening, 96 99:59:59,999 --> 99:59:59,999 and what we learned astonished us. 97 99:59:59,999 --> 99:59:59,999 Back in the dry south of Madagascar, we learned that one species 98 99:59:59,999 --> 99:59:59,999 was immensely important for villagers: 99 99:59:59,999 --> 99:59:59,999 this remarkable octopus. 100 99:59:59,999 --> 99:59:59,999 We learned that soaring demand was depleting an economic lifeline. 101 99:59:59,999 --> 99:59:59,999 But, we also learned that this animal grows astonishingly fast, 102 99:59:59,999 --> 99:59:59,999 doubling in weight every one or two months. 103 99:59:59,999 --> 99:59:59,999 We reasoned that protecting just a small area of fishing ground 104 99:59:59,999 --> 99:59:59,999 for just a few months 105 99:59:59,999 --> 99:59:59,999 might lead to dramatic increases in catches, 106 99:59:59,999 --> 99:59:59,999 enough to make a difference to this community's bottom line 107 99:59:59,999 --> 99:59:59,999 in a time frame that might just be acceptable. 108 99:59:59,999 --> 99:59:59,999 The community thought so too, opting to close a small area of reef 109 99:59:59,999 --> 99:59:59,999 to octopus fishing temporarily 110 99:59:59,999 --> 99:59:59,999 using a customary social code, 111 99:59:59,999 --> 99:59:59,999 invoking blessings from the ancestors to prevent poaching. 112 99:59:59,999 --> 99:59:59,999 When that reef reopened to fishing six months later, 113 99:59:59,999 --> 99:59:59,999 none of us were prepared for what happened next. 114 99:59:59,999 --> 99:59:59,999 Catches soared, 115 99:59:59,999 --> 99:59:59,999 with men and women landing more and bigger octopus 116 99:59:59,999 --> 99:59:59,999 than anyone had seen for years. 117 99:59:59,999 --> 99:59:59,999 Neighboring villages saw the fishing boom 118 99:59:59,999 --> 99:59:59,999 and drew up their own closures, 119 99:59:59,999 --> 99:59:59,999 spreading the model virally along hundreds of miles of coastline. 120 99:59:59,999 --> 99:59:59,999 When we ran the numbers, 121 99:59:59,999 --> 99:59:59,999 we saw that these communities, 122 99:59:59,999 --> 99:59:59,999 among the poorest on Earth, 123 99:59:59,999 --> 99:59:59,999 had found a way to double their money in a matter of months by fishing less. 124 99:59:59,999 --> 99:59:59,999 Imagine a savings account 125 99:59:59,999 --> 99:59:59,999 from which you withdraw half your balance every year 126 99:59:59,999 --> 99:59:59,999 and your savings keep growing. 127 99:59:59,999 --> 99:59:59,999 There is no investment opportunity on Earth 128 99:59:59,999 --> 99:59:59,999 that can reliably deliver what fisheries can. 129 99:59:59,999 --> 99:59:59,999 But the real magic went beyond profit, 130 99:59:59,999 --> 99:59:59,999 because a far deeper transformation was happening in these communities. 131 99:59:59,999 --> 99:59:59,999 Spurred on by rising catches, 132 99:59:59,999 --> 99:59:59,999 leaders from Andavadoaka joined force with two dozen neighboring communities 133 99:59:59,999 --> 99:59:59,999 to establish a vast conservation area along dozens of miles of coastline. 134 99:59:59,999 --> 99:59:59,999 They outlawed fishing with poison and mosquito nets 135 99:59:59,999 --> 99:59:59,999 and set aside permanent refuges 136 99:59:59,999 --> 99:59:59,999 around threatened coral reefs and mangroves, 137 99:59:59,999 --> 99:59:59,999 including, to my astonishment, 138 99:59:59,999 --> 99:59:59,999 those same sights that I'd flagged just two years earlier 139 99:59:59,999 --> 99:59:59,999 when my evangelism for marine protection was so roundly rejected. 140 99:59:59,999 --> 99:59:59,999 They created a community-led protected area, 141 99:59:59,999 --> 99:59:59,999 a democratic system for local marine governance 142 99:59:59,999 --> 99:59:59,999 that was totally unimaginable just a few years earlier. 143 99:59:59,999 --> 99:59:59,999 And they didn't stop there: 144 99:59:59,999 --> 99:59:59,999 within five years, they'd secured legal rights from the state 145 99:59:59,999 --> 99:59:59,999 to manage over 200 square miles of ocean, 146 99:59:59,999 --> 99:59:59,999 eliminating destructive industrial trawlers from the waters. 147 99:59:59,999 --> 99:59:59,999 Ten years on, we're seeing recovery of those critical reefs 148 99:59:59,999 --> 99:59:59,999 within those refuges. 149 99:59:59,999 --> 99:59:59,999 Communities are petitioning for greater recognition 150 99:59:59,999 --> 99:59:59,999 of the right to fish 151 99:59:59,999 --> 99:59:59,999 and fairer prices that reward sustainability. 152 99:59:59,999 --> 99:59:59,999 But all that is just the beginning of the story, 153 99:59:59,999 --> 99:59:59,999 because this handful of fishing villages taking action 154 99:59:59,999 --> 99:59:59,999 has sparked a marine conservation revolution 155 99:59:59,999 --> 99:59:59,999 that has spread over thousands of miles, 156 99:59:59,999 --> 99:59:59,999 impacting hundreds of thousands of people. 157 99:59:59,999 --> 99:59:59,999 Today in Madagascar, hundreds of sites are managed by communities 158 99:59:59,999 --> 99:59:59,999 applying this human rights-based approach to conservation 159 99:59:59,999 --> 99:59:59,999 to all kinds of fisheries from mud crabs to mackerel. 160 99:59:59,999 --> 99:59:59,999 The model has crossed borders through East Africa and the Indian Ocean 161 99:59:59,999 --> 99:59:59,999 and is now island-hopping into Southeast Asia. 162 99:59:59,999 --> 99:59:59,999 From Tanzania to Timor-Leste, from India to Indonesia, 163 99:59:59,999 --> 99:59:59,999 we're seeing the same story unfold, 164 99:59:59,999 --> 99:59:59,999 that when we design it right, 165 99:59:59,999 --> 99:59:59,999 marine conservation reaps dividends that go far beyond protecting nature, 166 99:59:59,999 --> 99:59:59,999 improving catches 167 99:59:59,999 --> 99:59:59,999 and driving waves of social change along entire coastlines, 168 99:59:59,999 --> 99:59:59,999 strengthening confidence, cooperation, 169 99:59:59,999 --> 99:59:59,999 and the resilience of communities to face the injustice of poverty 170 99:59:59,999 --> 99:59:59,999 and climate change. 171 99:59:59,999 --> 99:59:59,999 I've been privileged to spend my career 172 99:59:59,999 --> 99:59:59,999 catalyzing and connecting these movements throughout the tropics, 173 99:59:59,999 --> 99:59:59,999 and I've learned that as conservationists, 174 99:59:59,999 --> 99:59:59,999 our goal must be to win at scale, 175 99:59:59,999 --> 99:59:59,999 not just to lose more slowly. 176 99:59:59,999 --> 99:59:59,999 We need to step up to this global opportunity 177 99:59:59,999 --> 99:59:59,999 to rebuild fisheries: 178 99:59:59,999 --> 99:59:59,999 with field workers to stand with communities 179 99:59:59,999 --> 99:59:59,999 and connect them to support them to act and learn from one another; 180 99:59:59,999 --> 99:59:59,999 with governments and lawyers standing with communities 181 99:59:59,999 --> 99:59:59,999 to secure their rights to manage their fisheries; 182 99:59:59,999 --> 99:59:59,999 prioritizing local food and job security 183 99:59:59,999 --> 99:59:59,999 above all competing interests in the ocean economy; 184 99:59:59,999 --> 99:59:59,999 ending subsidies for grotesquely overcapitalized industrial fleets 185 99:59:59,999 --> 99:59:59,999 and keeping those industrial and foreign vessels 186 99:59:59,999 --> 99:59:59,999 out of coastal waters. 187 99:59:59,999 --> 99:59:59,999 We need agile data systems 188 99:59:59,999 --> 99:59:59,999 that put science in the hands of communities 189 99:59:59,999 --> 99:59:59,999 to optimize conservation to the target species or habitat. 190 99:59:59,999 --> 99:59:59,999 We need development agencies, donors, and the conservation establishment 191 99:59:59,999 --> 99:59:59,999 to raise their ambition to the scale of investment 192 99:59:59,999 --> 99:59:59,999 urgently required to deliver this vision. 193 99:59:59,999 --> 99:59:59,999 And to get there, 194 99:59:59,999 --> 99:59:59,999 we all need to reimagine marine conservation 195 99:59:59,999 --> 99:59:59,999 as a narrative of abundance and empowerment, 196 99:59:59,999 --> 99:59:59,999 not of austerity and alienation, 197 99:59:59,999 --> 99:59:59,999 a movement guided by the people who depend on healthy seas for their survival, 198 99:59:59,999 --> 99:59:59,999 not by abstract scientific values. 199 99:59:59,999 --> 99:59:59,999 Of course, fixing overfishing is just one step to fixing our oceans. 200 99:59:59,999 --> 99:59:59,999 The horrors of warming, acidification and pollution grow each day. 201 99:59:59,999 --> 99:59:59,999 But, it's a big step. 202 99:59:59,999 --> 99:59:59,999 It's one we can take today, 203 99:59:59,999 --> 99:59:59,999 and it's one that will give a much-needed boost 204 99:59:59,999 --> 99:59:59,999 to those exploring scalable solutions to other dimensions of our ocean emergency. 205 99:59:59,999 --> 99:59:59,999 Our success propels theirs. 206 99:59:59,999 --> 99:59:59,999 If we throw up our hands in despair, 207 99:59:59,999 --> 99:59:59,999 it's game over. 208 99:59:59,999 --> 99:59:59,999 We solve these challenges by taking them on one by one. 209 99:59:59,999 --> 99:59:59,999 Our overwhelming dependence on our ocean is the solution 210 99:59:59,999 --> 99:59:59,999 that has been hiding in plain sight, 211 99:59:59,999 --> 99:59:59,999 because there's nothing small about small-scale fishers. 212 99:59:59,999 --> 99:59:59,999 They're a hundred million strong 213 99:59:59,999 --> 99:59:59,999 and provide nutrition to billions. 214 99:59:59,999 --> 99:59:59,999 It's this army of everyday conservationists 215 99:59:59,999 --> 99:59:59,999 who have the most at stake. 216 99:59:59,999 --> 99:59:59,999 Only they have the knowledge and global reach needed 217 99:59:59,999 --> 99:59:59,999 to reshape our relationship with our oceans. 218 99:59:59,999 --> 99:59:59,999 Helping them achieve this 219 99:59:59,999 --> 99:59:59,999 is the most powerful thing we can do 220 99:59:59,999 --> 99:59:59,999 to keep our oceans alive. 221 99:59:59,999 --> 99:59:59,999 Thank you. 222 99:59:59,999 --> 99:59:59,999 (Applause)
