Short-term e ects of drawing water for connectivity of rivers and lakes on zooplankton community structure

During 28–29, September 2005, water was drawn from Hanjiang River and Houguan Lake to the Yangzi River via Sanjiao Lake and Nantaizi Lake in Wuhan in order to provide favorable conditions for ecosystem restoration. To evaluate the feasibility and validity of drawing water as a means of ecosystem restoration, zooplankton populations were studied 3 times (before, immediately after finishing and a month after drawing water) at seven locations from 27 Sept. 2005 to 2 Nov. 2005. Water quality in the lakes was mostly improved and zooplankton species richness decreased as soon as drawing water had finished but increased a month after drawing water. Zooplankton density and biomass was reduced in the lakes by drawing water but was increased at the entrance to Sanjiao Lake because of landform geometry change. Before drawing water, most species in Sanjiao Lake e.g., Brachionus sp. and Keratella sp. were tolerant of contamination. After drawing water oligotrophic-prone species such as Lecane ludwigii and Gastropus stylifer emerged. We conclude that drawing water could be important for improving water quality and favour ecosystem restoration. Dilution of nutrient concentrations may be an important role in the e ect.

A global Fordian compromise?—And what it would mean for the transition to sustainability

At first, it may seem as if the sustainable transition would force us to make a cynical trade-off between (a) the immediate needs of the global poor and (b) the future needs of the global rich. Crucial objectives, such as climate stability, are commonly held to be unattainable if the rest of the world would come to enjoy present Western living standards.Challenging this pessimistic analysis, this essay explores the possibility of opening up advanced technological paths to environmental sustainability by means of a “global Fordian compromise”. Built around trade reform, such a compromise would resemble its historic namesake by not seeking individual moral reform, as emphasized in environmental citizenship theory, but rather by drawing on the momentum of existing socio-economic dynamics.
