- Crunch time for saving environment on farmland April 18, 2018As the debate on the next EU budget draws to a close, will Budget Commissioner Oettinger dedicate enough to the environment and climate in the future Common Agricultural Policy (CAP) to avert disaster? Biodiversity is in freefall in Europe. Stories of the collapse of insects and birds, mostly related to intensive agriculture, have been hitting […]
- How do we spread word about the biodiversity crisis? Experts weigh in. April 16, 2018How do we raise awareness about the biodiversity crisis facing the world? This was the problem put to six experts (including Sir David Attenborough) at a panel held at BirdLife’s Cambridge office, the Cambridge Conservation Initiative, on 12 April. It’s a tough one. Right now, species are going extinct at a rate up to 1,000 […]
- “The world has cause for optimism”: Sir David Attenborough’s keynote speech April 13, 2018Biodiversity loss is a huge problem for the conservation community. Not only are extinctions occurring at a rate up to 1,000 times normal levels, but public awareness about this crisis is lagging far behind that of other environmental issues such as climate change. It was precisely to address this problem that the Godfather of modern […]

The results of surveys conducted on more than 50 lakes and lagoons that could hold breeding populations, including the six key waterbodies that held c.40% of the total population in the 1980s, suggest that the rate of decline may have been more rapid than previously thought (Imberti and Casañas 2010). When mean counts from the 1980s are summed across these six main sites, a total of 1,832 adults are estimated to have been recorded; however, surveys at these same sites in 2009 yielded records of only 117 adults. Furthermore, an estimated total of c.580 nests were recorded at these six sites during the 1980s, with not one found during the surveys in 2009 (Imberti and Casañas 2010). The difference in the number of adults recorded suggests that a decline of c.94% has occurred at these sites over c.24 years. This equates to a decline of 90.5% over the past 21 years, assuming an exponential trend. Continue reading
