00:01Thank you, thank you very much.
00:04I'm with eLeaf, and I'm very proud because that's a new company.
00:08We read the leaves.
00:10We read leaves from crops, from vegetation, and that gives us the opportunity...
00:15...to make real-time information, quantified for water and food security.
00:24So one of the biggest problems is that we have to go through a period...
00:29...of very fast growth, from seven to nine billion people.
00:33And FAO has calculated that we need 70 percent more food.
00:38Unfortunately, this takes also a lot of water...
00:41...but more water is now withdrawn to other sectors.
00:45So this agriculture has this big challenge...
00:48...of producing more food from less water; or, more crop per drop.
00:53How we do that? From satellites.
00:55Satellites come every day.
00:57They give good data, they give reliable data...
01:00...they have gone through tremendous investments in producing the data.
01:05But the pixels are dumb, you know? Just stupid pixels.
01:10If you download the data, then you get spectral reflectancies on watts per square meter...
01:16...per stare radiance, you know, which doesn't make sense.
01:19So we have pixel intelligence mapping, we make the pixels intelligent.
01:24That is what we do.
01:25We make the pixels intelligent.
01:27How can we apply that? Just one example.
01:30Only one example.
01:31This is about crops and water.
01:33So on the upper part of the curve, you see how crops grow.
01:37We use infra-red to measure leaf area index, to look at photosynthesis.
01:41And the lower part, we look at how much water is used.
01:44We use canopy temperatures, we use microwave data...
01:48...so that we can really have a good understanding on how much water is used.
01:54So crops have a dynamic cycle.
01:56They go through different development stages, so we need these images very regularly.
02:01We have to refresh our information at least one time per week, or maybe even twice a week.
02:07And this is an example of ArcGIS Online.
02:09You can have a look, there is in the folder on demoeleaf.info...
02:16...and you can see, for instance, the biomass prediction of entire China.
02:21If you combine that with maps of the crop layers, you can see...
02:25...how much biomass is produced for rice, for wheat, for cotton...
02:29...for all these interesting things.
02:30But also for your eucalyptus plantation.
02:32At the same time, we do that for evaporated transpiration...
02:35...so we can calculate how much water is used.
02:38We can do that with the satellites without going to the field...
02:42...getting dirty hands, dig into the soil, you know...
02:46...directly operational information...quantified information.
02:51The most important thing now on the agenda of the United Nations...
02:55...is improving water productivity. More crop per drop.
02:59So they want to calculate how much kilos can be obtained...
03:03...in terms of food, and how much water is used.
03:06This is an example of Imperial Valley, for which we have calculators...
03:10...for every 20- by 20-meter pixel, how much biomass is produced...
03:14...and how much water is used so we can calculate water productivity.
03:18You know, which is making real sense to get quantified information.
03:25Now, not only we do that for certain parts...
03:28...but we can scale it up to entire earth, and we have a score.
03:32The water productivity score.
03:34So you have the scale of Richter...
03:36...and that tells you immediately whether you're good or you are bad.
03:40We have now a score of water productivity.
03:43So if you have a four, you really have to improve.
03:46If you are a nine, you're already doing a very good job.
03:49So you can judge whether your state agency is doing good work.
03:57Then on the next one, here it comes...see, I would like to summarize the story.
04:09I have given you an example of water productivity that we can calculate from satellites.
04:13But we can do much more.
04:15We can have 50 data components.
04:17And by the end of this year, we will start on ArcGIS Online with our big 10.
04:22We start with the 10 major data components, and we will upload all that information.
04:28Why I'm here today is to invite you to think about smart solutions, okay?
04:33So if you're intrigued to work out applications...
04:37...smart solutions in terms of irrigation planners, irrigation performance, fertilizer management...
04:46...tree water use, water accounting, groundwater monitors, forest applications...
04:54...then you know, the only very simple thing to do is go and find us in the booth 217.
05:06Of course, in the Map Gallery, and on the website.
05:10Thank you very much.
