New publication: Multiple-scale land sparing

Some of my colleagues from Lund and I just published a new paper in Frontiers in Ecology and Evolution on what we call multiple scale sparing to widen the, often heated, debate on land sharing versus land sparing1

There is an ongoing debate on whether we should devote specific areas of non-crop habitats to conservation, segregated from high-yielding farmland, “land sparing”, or implement farming practices that integrate biodiversity and promote other services than crop yield “land sharing”. In our paper we argue that the debate over the relative merits of land sparing and land sharing is confused because the spatial scales to apply the land sparing or sharing differ widely in the debate. There might not be a single correct spatial scale for segregating biodiversity protection and commodity production in multifunctional landscapes.
In the article we discuss how this way of thinking on land sparing/sharing may overcome the apparent dichotomy between land sharing and land sparing. Hopefully, it can aid in finding acceptable compromises that conserve biodiversity and landscape multifunctionality.

New Institute of Agroecology

A while ago some researchers at the university, UNRN, among them a team from our group, have worked on an application for starting a new institute on Agroecology. It just got approved and we are pleased to now have the Instituto de Investigaciones en Recursos Naturales, Agroecología y Desarrollo Rural – IRNAD

Translated it mean “Institute of Research in Natural Resources, Agroecology and Rural Development. The idea is to work with questions on how to transform agriculture to produce food, increase food security and social development in a sustainable way. This require understanding and knowledge from many different disciplines and we aim to be an inter- and transdisciplinary research institute. We are already from the start an interdisciplinary group of researchers, which will hopefully increase with time.

If you want more information you can contact me or the Director of the Institute Lucas Garibaldi.

New publication; importance of non-bees

Recently our new publication on the importance of non-bee insects for crop pollination around the world was published online at PNAS.

 

We found that other insects than bees also are important for the pollination of crops. Examples of these non-bee pollinators are insects such as flies, beetles, moths, butterflies, wasps and ants. Non-bee pollinators were less effective than bees per flower visit however, they provided more visits.

As these other insects responds a bit different to e.g land-use changes than bees do, they can perhaps stabilize the pollinations service under environmental change.

As it is open access you can both read the abstract and download pdf here:
