Ecology: Conservation and food system changes needed to bolster biodiversity

Declines in terrestrial biodiversity from habitat conversion could be reversed by adopting a combination of bold conservation methods and increases in the sustainability of the food system, a modelling study published in Nature suggests.

 Human pressures, such as the destruction of natural habitats to make way for agriculture and forestry, are causing rapid declines in biodiversity, and placing at risk the ecosystem services upon which we depend. Ambitious targets for biodiversity have been proposed, but it is unclear how these targets can be achieved whilst retaining the ability to feed a growing population. Using land-use and biodiversity models, David Leclère and colleagues show how this is possible. 

 Conservationists need to increase the amount of actively managed land, restore degraded land and adopt generalized landscape-level conservation planning. Meanwhile, we need to eat fewer animal-derived calories, waste less food and find ways to intensify food production sustainably.

 If this double-pronged strategy is followed, more than two thirds of future biodiversity losses from habitat conversion could be avoided, the authors suggest. However, they caution that other threats, such as climate change, must also be addressed to truly reverse biodiversity declines.

Conservative MP Absent From a Child Poverty Forum in Southwestern Manitoba.

Are hungry kids a priority for the Harper government? by Larry Powell The forum (for the riding of Dauphin - Swan River - Neepawa) was sponsored by the Mission and Services Committee of the Neepawa United Church. It drew about 80 people to the church on Wednesday. But only four of the five candidates (see below) took part in the debate -  Ray  Piché  (Liberal),   Kate Storey (Green Party),  Inky Mark (Ind.) and  Laverne Lewycky (NDP) . The 5th candidate, the sitting Conservative MP for the area, Robert Sopuck (represented by the empty chair on the right), did not attend. His office manager in Neepawa, Christine Waddell, said he was in Inglis, a small community in the western part of the riding for the evening. She did not elaborate. But she did explain that a campaign worker was mistaken when he told forum organizers earlier that Mr. Sopuck would, in fact be there. Piché , the Liberal candidate, said the MP's absence showed “disrespect” for the rest of the candidates

A Candidate's Forum on Child Poverty Touches a Nerve in Manitoba.

by Larry Powell Planet In Peril has sorted through some of the confusion surrounding the absence of Robert Sopuck (above), the Conservative Member of Parliament for Dauphin-Swan River-Neepawa,  from a candidates' forum on child poverty in Neepawa on Wednesday.  About a month ago, his office told forum organizers that he would be attending.  But his office manager in Neepawa, Christine Waddell, later announced he could not attend due to "scheduling conflicts." She said the night of the event, he was in Inglis, a small town in the western part of his riding.  This morning, however, Sopuck himself told PinP he had actually been in Roblin, a larger town just north of Inglis. A newspaper ad indicated it was a "meet and greet" affair. But that was in the morning in Roblin, a town within a 3-hour drive of Neepawa. So it's still not clear what the event in Inglis was which took priority over a candidate's forum. The MP bristled at my suggestion th
