1 00:00:00,000 --> 00:00:03,311 SPEAKER: Hello, everyone, and welcome and congratulations. 2 00:00:03,311 --> 00:00:07,610 So I said that I would do two experiments or two lessons 3 00:00:07,610 --> 00:00:08,510 to learn from Mexico. 4 00:00:08,510 --> 00:00:10,070 I might only have time for one. 5 00:00:10,070 --> 00:00:15,930 So I want you to pay attention to this image because when you see this image, 6 00:00:15,930 --> 00:00:17,490 you'll see it again during my talk. 7 00:00:17,490 --> 00:00:21,620 But I want you to think, history is going to be one of my favorite classes 8 00:00:21,620 --> 00:00:22,850 that I take at Harvard. 9 00:00:22,850 --> 00:00:26,120 And if that wasn't the case in high school, maybe, and just maybe 10 00:00:26,120 --> 00:00:29,450 it's because you didn't have a great high school history teacher. 11 00:00:29,450 --> 00:00:33,620 12 00:00:33,620 --> 00:00:38,700 So how do we narrate histories of science and why does it matter? 13 00:00:38,700 --> 00:00:42,530 Why does it matter that we understand our past? 14 00:00:42,530 --> 00:00:46,310 History is one of the most politicized disciplines. 15 00:00:46,310 --> 00:00:49,910 There is a reason why politicians are constantly 16 00:00:49,910 --> 00:00:52,910 debating what should be taught in the classrooms 17 00:00:52,910 --> 00:00:55,010 and what should be part of the curriculum 18 00:00:55,010 --> 00:00:59,510 because if we don't understand our past or how our past is framed, 19 00:00:59,510 --> 00:01:04,379 it impacts the decisions in our present and in the future. 20 00:01:04,379 --> 00:01:07,580 So I'm going to quote from one of my favorite historians. 21 00:01:07,580 --> 00:01:11,480 He's a Haitian, or was a Haitian historian, Michel-Rolph Trouillot, 22 00:01:11,480 --> 00:01:15,720 who wrote Silencing the Past, the Power and the Production of History. 23 00:01:15,720 --> 00:01:19,110 And he said this about a particular event, 24 00:01:19,110 --> 00:01:23,210 "This is a story within a story so slippery at the edges 25 00:01:23,210 --> 00:01:29,780 that one wonders when and where it started and whether it will ever end." 26 00:01:29,780 --> 00:01:36,140 He was talking about the US invasion of Mexico in 1846. 27 00:01:36,140 --> 00:01:41,720 After that war ends, the United States takes 52% of Mexico's territory. 28 00:01:41,720 --> 00:01:44,180 And the configuration that we have today is 29 00:01:44,180 --> 00:01:49,510 the result of that treaty of so-called peace between our two nations. 30 00:01:49,510 --> 00:01:52,870 What if we began history lessons learning 31 00:01:52,870 --> 00:01:57,160 that our current geographic configuration is 32 00:01:57,160 --> 00:02:01,010 a result of an invasion of war? 33 00:02:01,010 --> 00:02:06,900 So when we begin our stories, and where we begin, is very important. 34 00:02:06,900 --> 00:02:10,850 We need to change our perspectives and flip the world 35 00:02:10,850 --> 00:02:16,910 to find new ways of thinking about where we live. 36 00:02:16,910 --> 00:02:20,300 So the when is really important but also is the where. 37 00:02:20,300 --> 00:02:26,000 As a historian, I begin my search for those answers in archives. 38 00:02:26,000 --> 00:02:29,030 So some archives look like this one in Mexico City, which 39 00:02:29,030 --> 00:02:30,560 is the foreign relations archive. 40 00:02:30,560 --> 00:02:32,120 And it's extraordinary. 41 00:02:32,120 --> 00:02:35,840 You have some of the best minds collecting and working 42 00:02:35,840 --> 00:02:37,040 on those archives. 43 00:02:37,040 --> 00:02:40,180 Other archives look like this. 44 00:02:40,180 --> 00:02:43,680 This is the ministry of agriculture, livestock, rural development, fisheries 45 00:02:43,680 --> 00:02:47,910 and food in Mexico as well, not far from the other one. 46 00:02:47,910 --> 00:02:53,370 Now, which stories do you think will be easier to emerge? 47 00:02:53,370 --> 00:02:56,970 But hidden in here are some extraordinary histories 48 00:02:56,970 --> 00:03:01,200 that we may never get to know, simply because of where they 49 00:03:01,200 --> 00:03:05,340 are located and so difficult to attain. 50 00:03:05,340 --> 00:03:08,130 As Harvard students, I will challenge you 51 00:03:08,130 --> 00:03:12,210 to reframe your questions to think of them differently and think 52 00:03:12,210 --> 00:03:15,530 about accessing these stories. 53 00:03:15,530 --> 00:03:19,130 And with that, we go back to this picture. 54 00:03:19,130 --> 00:03:22,730 Well, not yet. 55 00:03:22,730 --> 00:03:29,100 In the mid-20th century, when we were at war in the 1940s, in the United States 56 00:03:29,100 --> 00:03:30,370 there was a big concern. 57 00:03:30,370 --> 00:03:33,180 It was about national security, but not national security 58 00:03:33,180 --> 00:03:34,770 as you might understand it. 59 00:03:34,770 --> 00:03:38,800 There was a real concern that we might run out of food. 60 00:03:38,800 --> 00:03:43,260 We saw this during the COVID pandemic, that with trade disrupted, 61 00:03:43,260 --> 00:03:45,600 it was difficult to bring food in. 62 00:03:45,600 --> 00:03:48,400 So an idea was thrown out. 63 00:03:48,400 --> 00:03:53,290 What if we create with our allies on the Western hemisphere 64 00:03:53,290 --> 00:03:59,590 a way of thinking about producing more food by genetically engineering plants, 65 00:03:59,590 --> 00:04:03,160 but also by applying scientific ideas to the fields? 66 00:04:03,160 --> 00:04:05,440 And where will we begin those experiments? 67 00:04:05,440 --> 00:04:08,030 In the fields of Mexico. 68 00:04:08,030 --> 00:04:11,710 So it will be Mexico that will help us feed the world. 69 00:04:11,710 --> 00:04:14,770 When we think of who feeds the world, we don't immediately 70 00:04:14,770 --> 00:04:18,670 think of Mexico, or for that matter, the countries of the Global South. 71 00:04:18,670 --> 00:04:20,079 But we should. 72 00:04:20,079 --> 00:04:24,460 So in the 1940s, the Rockefeller Foundation, here in the United States, 73 00:04:24,460 --> 00:04:27,310 and the Mexican government come together and they 74 00:04:27,310 --> 00:04:31,660 devise what will be called the MAP, or Mexican Agricultural Program, 75 00:04:31,660 --> 00:04:36,640 applying science to crops to produce more food. 76 00:04:36,640 --> 00:04:39,700 The idea it was a problem of yield. 77 00:04:39,700 --> 00:04:43,780 If we could yield more crops, we would be able to feed the world. 78 00:04:43,780 --> 00:04:45,880 And it wouldn't matter if we were at war. 79 00:04:45,880 --> 00:04:49,840 The Western hemisphere would be safe. 80 00:04:49,840 --> 00:04:54,360 So if you see, this is the first image that you saw. 81 00:04:54,360 --> 00:04:56,940 And this is an experiment station in Mexico. 82 00:04:56,940 --> 00:05:00,690 What you see here, and as far as the horizon goes, 83 00:05:00,690 --> 00:05:03,510 these are all the experimental wheats that were 84 00:05:03,510 --> 00:05:06,820 devised in this one experiment station. 85 00:05:06,820 --> 00:05:12,100 There are so many that more than 60% of the world's wheat-- 86 00:05:12,100 --> 00:05:14,140 let me repeat that. 87 00:05:14,140 --> 00:05:19,180 More than 60% of the world's wheat is derived 88 00:05:19,180 --> 00:05:23,920 from varieties that were designed in this experiment station. 89 00:05:23,920 --> 00:05:29,410 That means that wheat in African nations, in Southeast Asia, 90 00:05:29,410 --> 00:05:35,710 in the Middle East can trace their varieties to one experimental station. 91 00:05:35,710 --> 00:05:42,580 Now, why haven't we learned about this, that more than 60% of the world's wheat 92 00:05:42,580 --> 00:05:49,120 was designed in one experimental station that traces its origins to that 1940s 93 00:05:49,120 --> 00:05:52,390 program that was a collaboration between the Rockefeller 94 00:05:52,390 --> 00:05:54,310 Foundation and the Mexican government? 95 00:05:54,310 --> 00:05:57,160 So let's learn a little bit about that. 96 00:05:57,160 --> 00:05:59,860 In the 1940s, as I told you-- and here you 97 00:05:59,860 --> 00:06:02,710 have bureaucrats from the Rockefeller Foundation 98 00:06:02,710 --> 00:06:06,100 who are designing this idea of how can we feed the world? 99 00:06:06,100 --> 00:06:09,210 How can we transform the food supply? 100 00:06:09,210 --> 00:06:12,990 So this question of food supply issues is not a new one. 101 00:06:12,990 --> 00:06:16,050 We've been dealing with this for decades. 102 00:06:16,050 --> 00:06:19,280 So they decide that they're going to create 103 00:06:19,280 --> 00:06:23,150 focusing on wheat, corn, and beans. 104 00:06:23,150 --> 00:06:25,310 But wheat wins out. 105 00:06:25,310 --> 00:06:28,160 And they're going to focus all of their scientific energies 106 00:06:28,160 --> 00:06:34,430 in producing a better variety of wheat, one that produces more, more grain. 107 00:06:34,430 --> 00:06:38,570 And when they're planting it in the outskirts of this experimental station 108 00:06:38,570 --> 00:06:43,610 for over a decade, in the mid-1960s around the world, 109 00:06:43,610 --> 00:06:48,460 there is a famine happening primarily in India and Pakistan. 110 00:06:48,460 --> 00:06:51,770 What they're going to do is those experimental seeds 111 00:06:51,770 --> 00:06:54,410 will be put on trucks-- this is in Mexico. 112 00:06:54,410 --> 00:06:57,920 And those trucks are heading to the port, where 113 00:06:57,920 --> 00:07:00,980 they will be shipped to South Asia. 114 00:07:00,980 --> 00:07:03,500 And the idea is that these Mexican seeds, which 115 00:07:03,500 --> 00:07:07,580 were called miraculous seeds, would be planted in Indian soil 116 00:07:07,580 --> 00:07:09,650 and in Pakistani soil. 117 00:07:09,650 --> 00:07:12,770 And they would produce more wheat, stopping the famine that 118 00:07:12,770 --> 00:07:15,050 was affecting so many people. 119 00:07:15,050 --> 00:07:19,380 And it was incredibly successful. 120 00:07:19,380 --> 00:07:23,280 These seeds are what launched what we now call the Green Revolution. 121 00:07:23,280 --> 00:07:27,240 And the Green Revolution, which was major use of fertilizers, 122 00:07:27,240 --> 00:07:30,960 of irrigation, of insecticides and pesticides, 123 00:07:30,960 --> 00:07:34,650 transformed how we do agriculture today. 124 00:07:34,650 --> 00:07:38,070 But not only did it transform how we produce agriculture, 125 00:07:38,070 --> 00:07:42,090 it also, within one generation, we realized we 126 00:07:42,090 --> 00:07:46,670 were polluting our ecology by using too many pesticides, 127 00:07:46,670 --> 00:07:50,840 too much irrigation from groundwater. 128 00:07:50,840 --> 00:07:55,940 So in that decade, what seemed to be an amazing scientific solution 129 00:07:55,940 --> 00:07:59,150 turned out to be a problem for today. 130 00:07:59,150 --> 00:08:03,380 The solution, which seemed accurate and necessary at that time, 131 00:08:03,380 --> 00:08:09,290 has created a series of ripple effects, not just on the human body, 132 00:08:09,290 --> 00:08:13,770 but on non-human animals and the environment. 133 00:08:13,770 --> 00:08:16,460 So out of that collaboration, today we have 134 00:08:16,460 --> 00:08:18,980 something that's called the International Maize and Wheat 135 00:08:18,980 --> 00:08:22,160 Improvement Center, which is headquartered in Mexico City. 136 00:08:22,160 --> 00:08:25,850 But it has research arms in 22 other nations. 137 00:08:25,850 --> 00:08:32,690 And it is a network of researchers and scientific ideas about how to farm. 138 00:08:32,690 --> 00:08:36,710 The main concerns today are biosafety. 139 00:08:36,710 --> 00:08:42,510 What are we going to do with diseases that can cross borders so easily? 140 00:08:42,510 --> 00:08:44,450 This is a picture from 2013. 141 00:08:44,450 --> 00:08:46,940 And what you have there are, at the time, 142 00:08:46,940 --> 00:08:51,770 the two richest men in the world, Carlos Slim, from Mexico, and Bill Gates. 143 00:08:51,770 --> 00:08:56,000 And what they were doing at Cimmyt, they were inaugurating that biosafety lab 144 00:08:56,000 --> 00:08:59,630 that you just saw because they realized that we're in another era, 145 00:08:59,630 --> 00:09:02,090 that we need new seeds. 146 00:09:02,090 --> 00:09:05,690 Just as that issue in 1943, where you needed 147 00:09:05,690 --> 00:09:11,020 to create a new plant, a new seed, we're in a different stage. 148 00:09:11,020 --> 00:09:14,850 And what we have is a new coming hunger, a famine 149 00:09:14,850 --> 00:09:20,020 that will emerge not because of war, but because of climate change. 150 00:09:20,020 --> 00:09:22,710 So what kind of seeds will be needed? 151 00:09:22,710 --> 00:09:25,320 What kind of seeds will be designed? 152 00:09:25,320 --> 00:09:26,400 And guess what? 153 00:09:26,400 --> 00:09:29,060 It's happening again in Mexico. 154 00:09:29,060 --> 00:09:33,050 So when we think about where seeds and seed research is being done, 155 00:09:33,050 --> 00:09:38,540 yes, we have that network of seeds, of plant and crop research. 156 00:09:38,540 --> 00:09:46,060 But we also have one of the largest seed banks outside of Mexico. 157 00:09:46,060 --> 00:09:49,170 So what does that mean in my remaining minute? 158 00:09:49,170 --> 00:09:52,080 In my own research, I knew that story. 159 00:09:52,080 --> 00:09:53,520 But I knew that there was more. 160 00:09:53,520 --> 00:09:58,260 And I needed to go to India to find the connecting story. 161 00:09:58,260 --> 00:10:03,840 What I found there was that similarly, once those Mexican seeds in the 1940s 162 00:10:03,840 --> 00:10:07,320 made it to India, they were researched on 163 00:10:07,320 --> 00:10:10,230 and developed new types of varieties. 164 00:10:10,230 --> 00:10:14,250 But we still don't have full answers because we still 165 00:10:14,250 --> 00:10:16,570 have hunger in our world. 166 00:10:16,570 --> 00:10:20,340 And I said, how is it possible that we don't understand these histories 167 00:10:20,340 --> 00:10:21,795 or that we don't know about them? 168 00:10:21,795 --> 00:10:26,430 It turned out when I went to that initial research station, 169 00:10:26,430 --> 00:10:31,050 the stories of farmers, of Mexican scientists, were not found. 170 00:10:31,050 --> 00:10:36,570 Rather, what was known, was the story of Norman Borlaug, whom we 171 00:10:36,570 --> 00:10:38,700 might know from the Green Revolution. 172 00:10:38,700 --> 00:10:41,910 And he's considered the father of the Green Revolution. 173 00:10:41,910 --> 00:10:46,050 By understanding the stories of the farmers, of the scientists, 174 00:10:46,050 --> 00:10:50,430 and of the research station, we gathered a new understanding. 175 00:10:50,430 --> 00:10:53,940 And it's with the farmers that the answers lay, 176 00:10:53,940 --> 00:10:57,150 a collaboration between the farmers and the scientist 177 00:10:57,150 --> 00:11:00,480 and not just a focus on the science. 178 00:11:00,480 --> 00:11:04,200 And here, as my departing message, I just 179 00:11:04,200 --> 00:11:07,110 want to show you what the farmers have done. 180 00:11:07,110 --> 00:11:13,080 They have created a 365, seven days, 24 hour a week. 181 00:11:13,080 --> 00:11:16,950 What they're doing there is mapping the amount of water in the valley. 182 00:11:16,950 --> 00:11:20,910 They have designed to the litre the amount of water 183 00:11:20,910 --> 00:11:24,600 that is needed to produce more crops because this valley is found 184 00:11:24,600 --> 00:11:26,800 on the outskirts of the Sonoran Desert. 185 00:11:26,800 --> 00:11:31,810 So they have had to use 22nd century technology 186 00:11:31,810 --> 00:11:35,290 in order to envision a future that came too early. 187 00:11:35,290 --> 00:11:38,620 They were designing seeds for a warming climate. 188 00:11:38,620 --> 00:11:41,860 And the climate has changed so quickly that the seeds 189 00:11:41,860 --> 00:11:46,060 that they were designing, they have to rethink what they're doing now. 190 00:11:46,060 --> 00:11:51,480 So my last words is think about that field, how you frame 191 00:11:51,480 --> 00:11:53,670 questions, how you think about history. 192 00:11:53,670 --> 00:11:58,170 When we think we have the answer, the impact and the ripple effect 193 00:11:58,170 --> 00:12:02,450 might be more different than you thought Thank you so much. 194 00:12:02,450 --> 00:12:06,000
