 Those three sectors, the water, food, and energy, those sectors are key for human survival. The more people we are, the more pressure on those resources, the stronger the interlinkages become. The three elements are really closely linked. You can't basically look at any sector in isolation. If you take the water sector, there's really close links with the energy sector. If you take the energy sector, there's close links with the food sector. And the food sector also, you can't just look at the food sector in isolation. An illustrating example is the energy sector. Now, say if a European government or some government say, OK, we would like to have 10% of our energy from biofuels, then that has enormous implications for the water sector, but also for the food sector. Because the food sector is basically competing or can be competing for the same land resources and water resources. So it takes enormous quantities of water to produce biofuels, but also to produce food. So you see that those kind of links are strong. You see that many decisions that relate to water and to water management are actually taken outside of the water sector. So that is why it is really important that you look at those three sectors as one unit and interlinkages between those sectors. We all know that because of the population growth, because of changes in diets, maybe some people say that, some estimates say that we nearly need to double the food production. But of course, with the same resources, we don't have more resources than we have. So that resources are energy and those resources are water. So we need to produce nearly twice as much food with the same amount of water and the same amount of energy. We do some research in Ethiopia, spate irrigation, they call it. So on a certain time in the year you get these floods, and the rest of the year the river is basically dry. So if the flood comes, the farmers, they try to get that flood, direct that flood into their fields to produce one crop per year. So without that water, without those flesh floods, they would have basically no food production except maybe livestock production. So of course, if the water is on the field, it also infiltrates. So you get also a replenishment of shallow groundwater, and that shallow groundwater is then again used for domestic purposes. So you see a multiple uses of water resources there. I do think it's an incredible important topic and you see that there's a lot of attention also from many countries. So we are quite fortunate here in UNESCO IT to have so many good MSC students, good PhD candidates who all give their little contribution to this huge global problem.
