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... 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00:41...but more water is now withdrawn to other sectors.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... 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

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... 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... 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... improving water productivity. More crop per drop.

02:59So they want to calculate how much kilos can be obtained... 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... 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.
