Often, conservation competes with food production by promoting less intensive farming and/or unfarmed reserves
Given that food production is essential for human wellbeing, what’s the best way of reconciling this trade-off?
To share, or spare; that is the question

We compared land sharing and land sparing scenarios (+ intermediate ones) all of which, crucially, produce the *same amount of food* overall.
We also evaluated a ‘three compartment sparing’ scenario (far right) which combines elements of both sharing and sparing

We used density-yield curves to estimate the regional population size of breeding birds under each scenario.
We fitted these curves separately for breeding birds in 2 regions of southern England: The Fens & Salisbury Plain

1 #BOU18TC The #HouseSparrow disappears from rural and urban areas of #Europe. Cities like Prague, London (#RedList in 2002) & Valencia have experienced #urban #declines in their populations above 50%. What is happening in urban areas? #ornithology #urbanecology #urbanbirds
2 #BOU18TC Various potential causes for the urban #decline have been suggested. Our aim was to study if new #park policies linked to #urbanization and #reurbanization (new concept) could be a key factor for the urban decline of the #species. #ornithology #urbanecology #urbanbirds
3 #BOU18TC We studied the abundance of #housesparrows (point counts) in 32 #urbanparks of 4 towns of eastern #Spain. 10 of them were modified (new park policies) during the 4 studied seasons 2015-2018. We compared means of (r) and abundance between years and kinds of parks.
