The pace of development is the major challenge to the efforts for environmental conservation in Abu Dhabi, according to the recently appointed Secretary General of Environment Agency, Abu Dhabi. \"Economic development is progressing much faster than our understanding of their impact on the environment, which can lead to very costly solutions and measures,\" Razan Khalifa Al Mubarak told Gulf News in an exclusive interview. It is critical that the environment is being considered at the planning stage and not just as an afterthought, she said. Razan said Abu Dhabi is blessed with amazing biodiversity and natural resources. However, with the population predicted to more than double between now and 2030, there will be increased demand for land to build on as well as energy, water, food and other products, she said.
