Abstract
1. Understanding how biodiversity responds to intensifying agriculture is critical
to mitigating the trade-offs between them. These trade-offs are particularly
strong in tropical and subtropical deforestation frontiers, yet it remains unclear
how changing landscape context in such frontiers alters agriculture–biodiversity
trade–offs.
2. We focus on the Argentinean Chaco, a global deforestation hotspot, to explore
how landscape context shapes trade-off curves between agricultural intensity
and avian biodiversity. We use a space-for-time approach and integrate a large
field dataset of bird communities (197 species, 234 survey plots), three agricul-
tural intensity metrics (meat yield, energy yield and profit) and a range of environ-
mental covariates in a hierarchical Bayesian occupancy framework.
3. Woodland extent in the landscape consistently determines how individual bird
species, and the bird community as a whole, respond to agricultural intensity.
Many species switch in their fundamental response, from decreasing occupancy
with increased agricultural intensity when woodland extent in the landscape is
low (loser species), to increasing occupancy with increased agricultural intensity
when woodland extent is high (winner species).
4. This suggests that landscape context strongly mediates who wins and loses along
agricultural intensity gradients. Likewise, where landscapes change, such as in
deforestation frontiers, the very nature of the agriculture–biodiversity trade–offs
can change as landscapes transformation progresses.
5. Synthesis and applications. Schemes to mitigate agriculture–biodiversity trade–offs,
such as land sparing or sharing, must consider landscape context. Strategies that
are identified based on a snapshot of data risk failure in dynamic landscapes, particu-
larly where agricultural expansion continues to reduce natural habitats. Rather
than a single, fixed strategy, adaptive management of agriculture–biodiversity
