Conservation planning can be challenging due to the need to balance biological concerns about population viability with social concerns about the benefits biodiversity provide to society, often while operating under a limited budget. Methods and tools that help prioritize conservation actions are critical for the management of at-risk species. Here, we use a multi-attribute utility function to assess the optimal maternity roosts to conserve for maintaining the population viability and the ecosystem services of a single species, the Mexican free-tailed bat (Tadarida brasiliensis mexicana). Mexican free-tailed bats provide ecosystem services such as insect pest-suppression in agricultural areas and recreational viewing …

Honey bee colony losses are a major concern in the US and across the globe. Long-term data on losses are critical for putting yearly losses in context. US colony loss surveys have been conducted yearly since the winter of 2006-7. Here we report the results from the eighth annual survey on winter losses, and the second annual survey of summer and annual losses. There were 7,425 valid respondents (7,123 backyard, 190 sideline, and 112 commercial beekeepers) managing 497,855 colonies, 19% of the total US colonies. Total losses reported were 19.8% [95% CI: 19.3-20.3%] over the summer, 23.7% [95% CI: 23.3-24.1%] …

Envisioning A Future Without Food Waste And Food Poverty, Luis González Vaqué, A. Arroyo Aparicio Dec 2014

Envisioning A Future Without Food Waste And Food Poverty, Luis González Vaqué, A. Arroyo Aparicio

Luis González Vaqué

Different factors have contributed to what is known as the Contemporary Food Paradox. To express this more graphically, let us say that more than a third of the food in the world is wasted while almost 800 million people suffer extreme malnutrition. Now the Millennium Goals’ deadline expired, we must set the targets for the Sustainable Development Goals for the next decades. Many national and international organizations point out the imperative need to give an adequate reply to this paradox.

Food waste has important economic and environmental implications and, in addition, there is an undeniable ethical and social justice aspect. …
