Zanzibar: The Essential Mangrove | Climate Next by AWS
Zanzibar: The Essential Mangrove | Climate Next by AWS
Absorption of carbon dioxide, preservation of biodiversity, the reversal of coastal erosion, and the filtering of pollutants play a critical role in creating a sustainable future. In episode one of a four-part documentary series from AWS, we explore how mangroves play an essential role in protecting African communities from the impacts of climate change. Follow student-led YouthMappers and Digital Earth Africa in the quest to help communities gain fast access to decision-ready satellite data to prioritize restoration efforts of Mangroves along African coast lines.

2.335 -> I knew this island when I was a child,
7.465 -> and there were a lot of fish.
12.846 -> But, right now the flood is threatening peace.
19.144 -> The pressure of the salt water
20.562 -> is coming in the villages.
24.524 -> Without mangrove,
25.567 -> after maybe 20-25 years,
28.653 -> Zanzibar will disappear.
31.948 -> No Zanzibar.
35.869 -> I hope things will change.
66.983 -> I'm Zanzibarian,
68.234 -> and I'm living in these
69.527 -> small islands
71.196 -> in Zanzibar,
72.572 -> and I personally
74.157 -> experience the
75.366 -> impacts of the climate change
77.327 -> to my localities.
80.455 -> Damage of the houses.
82.749 -> Damage of the infrastructure.
85.543 -> Displacement of the people
87.295 -> from one place to another.
89.339 -> Brackish drinking water.
91.8 -> Because of the impact of
93.885 -> the climate change
94.886 -> that is salt water intrusion,
97.68 -> this is happening now.
101.643 -> When we have mangroves
103.311 -> along the coastal area,
105.313 -> they’re used to protect
107.232 -> the earth from
108.441 -> coastal erosion.
113.404 -> Mangrove is nursery for fish
115.365 -> because the small fish live in
117.117 -> upper roots of mangroves.
120.203 -> Mangroves play essential role
122.58 -> to the society
124.165 -> by absorbing large amount
126.501 -> of the carbon dioxide.
129.587 -> Mangroves has ability to absorb about
132.382 -> three to four times
134.384 -> the carbon dioxide
135.802 -> over the other forests.
138.972 -> Climate change impacts
140.807 -> the survival
141.766 -> of these mangrove.
146.938 -> Anthropogenic influences
149.149 -> severely impact the mangroves
151.526 -> and the ecosystem.
153.778 -> They're cutting down
155.071 -> these mangroves
156.239 -> because of their man-made activities.
158.908 -> They prefer
159.617 -> firewood material
160.869 -> from those mangroves.
164.038 -> They were not aware
165.415 -> of the advantages of mangrove
167.625 -> and also they were not aware
169.419 -> on the impact of the climate change.
172.63 -> What are the proper measure
174.674 -> to be taken
176.176 -> so as to combat these impacts?
189.063 -> YouthMappers are student-led chapters
191.316 -> around the world,
192.567 -> and they help
194.068 -> in creating and utilizing the open data.
199.157 -> With the open data,
200.533 -> they help in portraying
202.076 -> what is happening
203.036 -> in the community
203.995 -> and what people are facing
205.33 -> across the world.
207.04 -> What they do is
208.041 -> they create maps,
209 -> and they create mappers.
214.13 -> They make sure that
215.006 -> they extract the data from the community
217.133 -> because the community - they have
218.676 -> more knowledge on their environments.
222.931 -> I will use this to take
224.432 -> the area that is affected with climate change,
227.352 -> like coastal area,
228.519 -> and to visualize,
229.687 -> to my society,
230.772 -> to see this is real effect.
233.983 -> But in addition to that,
235.109 -> they also give them education
237.153 -> on climate change.
240.365 -> The students build their capacities,
242.575 -> and they learn new tools,
244.994 -> new technologies that are available.
247.538 -> And from there,
248.581 -> they help in creating open data,
250.541 -> and open data is used
251.834 -> by the government and by
253.211 -> other different stakeholders
254.629 -> to make informed decisions.
258.299 -> Digital Earth Africa
260.301 -> is a platform
261.302 -> that offer
262.136 -> ready-made satellite data.
267.6 -> As a geoinformer,
269.06 -> I have skills of Earth observation data,
272.397 -> on how to use
273.606 -> geospatial tools to solve the problem
276.442 -> that the Earth is facing today.
279.153 -> Through these technologies, such as
281.281 -> Earth observation data,
282.824 -> we can have information
284.701 -> that show
285.868 -> the Earth now and before.
291.207 -> We can use spatial data
292.625 -> in mangroves to
294.043 -> see if the mangroves, have been destroyed
296.462 -> in past few years
297.672 -> or the mangroves
298.84 -> have been grown
300.133 -> or any change
301.301 -> that has been taking place
303.011 -> in a certain area.
304.721 -> Because we can convert that data
306.306 -> in a real map
308.224 -> and then we can use it to
309.684 -> get different ideas
311.227 -> and decisions.
314.188 -> They can understand from those images
316.983 -> as this is the place
318.401 -> where people go and cut the trees.
324.198 -> Through Digital Earth Africa,
325.95 -> people they’re sharing their knowledge.
328.745 -> The guys who made that platform,
330.121 -> Dr. Ken,
331.372 -> he's willing to help everyone
333.708 -> to understand what they're doing there,
335.877 -> to share,
336.753 -> to do.
340.84 -> The big data that is availed
342.717 -> through the various platforms,
343.676 -> like Digital Earth Africa running on AWS,
346.429 -> these are the game changers.
348.264 -> The information on the Digital Earth Africa platform
350.85 -> helps the State University of Zanzibar
353.436 -> lecturers and YouthMappers
355.48 -> to actually
356.773 -> be able to get more information
358.149 -> about the trends,
359.484 -> which is availed from the analysis ready data.
362.653 -> Looking at the sum of the products
364.364 -> we've developed with Khairiya and students,
366.824 -> the one from mangrove changes.
369.994 -> So, they'll actually see
370.912 -> there was a rise in mangroves in this area,
372.747 -> or maybe there was a loss of mangroves
374.248 -> in certain areas.
375.5 -> So they can actually see
376.751 -> the areas they need to prioritize
378.92 -> and also help us
379.879 -> in validating what they get from the platform,
382.215 -> for us to improve our processing.
384.801 -> As the image in the Digital Earth Africa
387.011 -> spans over 30 years plus,
389.472 -> they’ve been able to
390.473 -> get time series analysis of the mangroves
392.767 -> and see some of the areas
394.268 -> how the trends have been.
396.312 -> Initially, they started with the Landsat data 30 meters,
398.856 -> and now they're using Sentinel-2 at 10 meters.
402.068 -> They're able to get much, much
403.277 -> more information.
405.405 -> At Digital Earth Africa,
406.697 -> we are dealing with petabytes of information.
409.158 -> It has to be on a web service,
410.451 -> where we can actually update it
411.828 -> as much as possible.
413.413 -> We are looking also going
414.58 -> beyond five petabytes
415.957 -> for the continent.
418.501 -> Land cover changes.
420.795 -> We can observe climate variability
424.298 -> to model maybe the floods.
426.008 -> To model the coastal erosion
427.301 -> so as,
428.386 -> if you want maybe to add some features
430.763 -> to that model,
431.931 -> you can do that in Digital Earth Africa.
436.018 -> We are working with Raya,
437.437 -> who’s been able to mentor the students.
439.689 -> Khairiya has been able to
441.482 -> showcase the value for mangroves
443.568 -> assessment using the Digital Earth Africa platform.
447.238 -> The values of citizen-generated science
449.24 -> and the champions
450.491 -> is giving out very strongly.
455.621 -> I have already gained the knowledge
458.166 -> about climate change,
460.418 -> and I will use that knowledge
462.962 -> to instruct others,
464.964 -> to teach others,
466.799 -> to engage with the groups
469.135 -> that perform the activities
471.846 -> to reduce the climate change.
473.848 -> And as you know,
475.057 -> everywhere now,
476.225 -> climate change, climate change is an issue.
478.811 -> So I hope that
480.146 -> this will be reduced,
482.148 -> but the technology is required for it.
487.862 -> The champions,
488.446 -> they’re actually the driving force
489.614 -> of some of the needs and priorities
491.324 -> of our products.
492.408 -> So, once we engage
493.826 -> with these champions,
494.619 -> they’ll tell us what they want to see.
496.204 -> They want more data,
497.497 -> higher resolution,
498.456 -> we listen to them.
500.625 -> This gives us a motivation to see
502.543 -> what other products and data
503.836 -> we could actually add
505.004 -> from our side
506.005 -> to deliver
506.964 -> the service to everyone in the continent.
511.01 -> And I hope
512.094 -> through these technologies,
513.804 -> they can help us to
515.431 -> provide awareness to the communities
517.642 -> on what is the role of the mangroves to the society.
520.937 -> So now, they're realizing that,
522.939 -> "Oh, we are not supposed to cut this tree,
526.192 -> and instead, we have to plant this tree
529.278 -> as much as possible."
534.992 -> Some of the YouthMapper students
537.203 -> are also volunteering at ZAVECO.
539.664 -> And one of the projects that they do
541.332 -> is to plant more mangroves.
543.584 -> So they preserve the areas
545.211 -> with their mangroves,
546.671 -> and they try to
548.172 -> make sure that they
549.59 -> plant more and more.
552.718 -> Just cutting maybe one,
554.345 -> planting twenty-five,
556.806 -> or cutting two,
558.224 -> just planting one thousand.
560.768 -> We have more than
562.228 -> two hundred people now,
563.437 -> planting every Saturday.
565.189 -> And we have plan that when you arrive here,
568.442 -> one thousand seeds.
571.487 -> Our nursery, in one day.
574.782 -> At State University of Zanzibar
576.742 -> they’re training their students
577.952 -> so the students will be the champions.
580.037 -> And one day in the future,
581.706 -> the student might be the president of
583.457 -> Tanzania or somewhere.
584.875 -> So, they'll be able to use this to make
586.877 -> very good informed decisions.
589.922 -> In Africa, we say that,
591.549 -> “Alone you can move faster,
593.175 -> however,
593.968 -> as a village,
594.677 -> we can actually move farther.”
597.93 -> We join hands,
599.14 -> and we join our forces
600.558 -> in making sure
601.434 -> we combat these climate change issues.
