24 May 2015, Los Angeles Times: Turning sewage into drinking water gains appeal as drought lingers. ‘s a technology with the potential to ease California’s colossal thirst and insulate millions from the parched whims of Mother Nature, experts say. But there’s just one problem — the “yuck factor.” As a fourth year of drought continues to drain aquifers and reservoirs, California water managers and environmentalists are urging adoption of a polarizing water recycling policy known as direct potable reuse. Unlike nonpotable reuse — in which treated sewage is used to irrigate crops, parks or golf courses — direct potable reuse takes treated sewage effluent and purifies it so it can be used as drinking water. It’s a concept that might cause some consumers to wince, but it has been used for decades in Windhoek, Namibia — where evaporation rates exceed annual rainfall — and more recently in drought-stricken Texas cities, including Big Spring and Wichita Falls.

14 May 2015, The Conversation: Single-crop farming is leaving wildlife with no room to turn. Rolling plains of wheat, endless fields of flowering canola, row upon row of fruit trees: these agricultural landscapes are the stuff of stunning photographs. Filling these paddocks with just one crop, known as monoculture, is a relatively easy, common and efficient way to produce food and fibre. But international research shows that these monocultures can be bad for the environment and production through effects on soil quality, erosion, plants and animals, and ultimately declining crop yields. Research I have published this week in the International Journal of Agricultural Sustainability shows a possible link between monoculture landscapes and fewer wild pollinators. Read More here
