Climate Change The impact of climate change is enormous. It leads to floods, food and water shortage and extreme weather events. Climate change is therefore the key driver of many of the world’s largest problems and crises of today. Lack of safety, lack of future perspective and lack of resources lead to poverty, inequality, political instability and war. Climate change is caused by degraded land and broken hydrological cycles as a result of dysfunctional ecosystems, in combination with the disproportional burning of fossil fuels. This has led to an excess of greenhouse gases in the atmosphere. The two greenhouse gases carbon dioxide (CO2) and water vapour have the largest contribution to global warming and related extreme weather events (more than 75%). The Solution Emission reductions alone are not sufficient to remove the excess of CO2 and prevent long term impacts of climate change. The excess of CO2 can best be reduced to safe levels by increasing natural sinks: carbon capture. This can be achieved by worldwide restoration of ecosystems. CO2 will be stored in ecosystems and the soil in a natural way by photosynthesis and will bring the amount in the atmosphere back to safe levels. The fertility and productivity of the soil will be enriched and feed the ecosystems in return. For us an ecosystem consist of more than only the biological component, we see human as a part of an ecosystem. Men has to help recovering it, but will also benefit from it, in many ways. Our Contribution The Weather Makers found a way to effectively regreen degraded areas by engineering ‘watershed wide’ and make use of interventions at the coastal zone and on-land simultaneously. We focus on restoring ecosystems in conjunction with the restoration of hydrological cycles: start restoring ecosystems at the best location in the watershed to achieve the best results. Functional ecosystems are able to feed the whole watershed with organic matter and restore healthy biological cycles. This will boost organic productivity in the watershed and make a sustainable society possible. We have developed Pro-Active Adaptive Realization which is a powerful method for design and execute ecosystem restoration projects. The core of the methodology consists of continuously monitoring the actual results and validate/ calibrate the forecasts. The method helps to combine multidisciplinary expertise and to overcome complexity of engineering. The results become open source and create an intelligent continuous self-learning loop for all parties involved, improving collective knowledge and communication. It facilitates a flexible execution with opportunities for optimisations. Pro-Active Adaptive Realization: working with a vision and be flexible and adaptive to new opportunities.
