As the need for fresh water increases, growing populations across the globe will increasingly turn to groundwater to slake their thirst. But where will we find that water? UNESCO's World-wide Hydrogeological Mapping and Assessment Programme (WHYMAP) created this map, along with several others, to serve as a guide to the world's groundwater resources in aquifers and other groundwater environments.

Recently the town of Heerlen in the Netherlands repurposed an old abandoned coal mine into a brilliant source of geothermal energy. The project takes advantage of flooded underground mine shafts, using their thermal energy to power a large-scale district heating system. Dubbed the Minewater Project, the new system recently went online and provides 350 homes and businesses in the town with hot water and heating in the winter and cool water in the summer.

Soil organic matter is what makes dirt fertile and able to support plant life - both of which are especially important for agriculture. Organic matter retains water in the soil and prevents erosion. Natural processes of decomposition of soil organic matter provide plants and microbes with the energy source and water they need to grow, and carbon is released into the atmosphere as a by-product of this process. Warming temperatures are expected to speed up this process which will increase the amount of CO2 that is transferred to the atmosphere.

VIVACE stands for Vortex Induced Vibrations for Aquatic Clean Energy. It doesn't depend on waves, tides, turbines or dams. It's a unique hydrokinetic energy system that relies on "vortex induced vibrations." Vortex induced vibrations are undulations that a rounded or cylinder-shaped object makes in a flow of fluid, which can be air or water. The presence of the object puts kinks in the current's speed as it skims by. This causes eddies, or vortices, to form in a pattern on opposite sides of the object. The vortices push and pull the object up and down or left and right, perpendicular to the current.

Bringing Wisdom to Emerging Technology We are at an amazing and critical juncture in human history. If we continue on our current path, we face many potential disasters: overpopulation, shortages of water, oil, and raw materials, financial instability, disease, terrorism, war, and the destruction of species and ecosystems (eg. see Jeffrey Sachs "Common Wealth: Economics for a Crowded Planet"). But the next few decades will also bring advances in science and technology which may dramatically improve our lives. It is remarkable that we are simultaneously on the verge of major revolutions in biology, neuroscience, psychology, artificial intelligence, nanotechnology, and fundamental physics.

The most disruptive idea being explored by startups is to channel coal stack carbon dioxide emissions into water filled bags with carbon-eating algae which can re-purpose carbon and hydrogen into fatty acids which can be used to create liquid biofuels.

Solving the "digital divide" in Africa will not put food in mouths, knowledge in heads, clean water in households, or make healthcare accessible to those who need it most. Leveraging knowledge, skills, and capacities holds out the possibility of doing all of these things. This is what extending knowledge infrastructure is about: building robust and sustainable networks and communities that mobilize a broad range of information practices, institutions, and technologies (old and new) - and put these in the service of locally-defined needs, aspirations, and broad developmental goals. This report summarizes current thinking and action around African knowledge infrastructures.
