Although the challenges posed by climate change are immense and some of the issues are new, elements of the solutions and most of the technologies needed to stabilize global warming are well-known and already available on the market. This is true also for adaptation to climate change: once the risks and necessary solutions have been identified and prioritized, it is often possible to use familiar techniques, such as efficient irrigation methods to improve water security and to combat water stress or the planting of mangrove forests to protect coastal zones. In many instances, we do not have to reinvent the wheel. In these cases, GTZ is stepping up its efforts to encourage the rapid dissemination of proven, efficient and locally appropriate solutions. Here, innovative approaches are only needed to overcome obstacles to the dissemination of the solutions.
