vIn June 2013, the Nicaraguan government granted a concession to a Hong Kong company to build a canal connecting the Pacific Ocean and the Atlantic Ocean, through the Caribbean Sea. The HK Nicaragua Canal Development Investment Company (operating as HKND Group) signed a 50-year lease, renewable for another 50 years. It started to break ground in December 2014. In our view, this canal could create an environmental disaster in Nicaragua and beyond. The excavation of hundreds of kilometres from coast to coast, traversing Lake Nicaragua, the largest drinking-water reservoir in the region, will destroy around 400,000 hectares of rainforests and wetlands.The accompanying development could imperil surrounding ecosystems.
