    Abstract Protected areas (PAs) are essential for biodiversity conservation, but their restrictive policies could accentuate poverty. Such a possibility may occur with the more restrictive PAs (e.g., national parks), which prioritize conservation while limiting the use of natural resources. However, less restrictive PAs, such as biosphere reserves, which allow the sustainable use of natural resources, may be better at alleviating poverty. However, such permissibility may reduce the effectiveness of preventing deforestation. Here, we assessed this conservation-development tradeoff by testing changes in marginalization (an indicator of poverty) and forest loss between two contrasting PAs management scheme types (MST, national parks and biosphere reserves) in Mexico. We quantified forest loss inside PAs and unprotected areas during the 2000–2019 period. Also, we contrasted marginalization changes during the 2000–2020 period between municipalities included in PAs (n = 288) and municipalities not directly influenced by PAs (n = 1615). Using a matching analysis approach, we tested for differences in forest loss and marginalization between protected and unprotected areas and between MST, in all cases controlling for the potential effects of confounding factors (e.g., slope, altitude, distance to cities, economic sector). We also evaluated potential conservation-development trade-offs resulting from the interaction of MST with the biophysical-socioeconomic context. PAs did not accentuate marginalization comparing unprotected areas. After matching, both national parks and biosphere reserves showed similar average changes in marginalization and forest loss probability. However, national parks showed higher marginalization than biosphere reserves in areas far from cities and sites with poor agriculture suitability, probably because restrictive policies in such adverse contexts might work against the development of the local communities. Also, national parks showed higher forest loss than biosphere reserves in areas suitable for agriculture. Our results suggest that, in the Mexican protected areas system, the interaction between MST and biophysical-socioeconomic contexts may lead to conservation-development tradeoffs. The more restrictive MST does not provide greater protection to the forest than the less restrictive MST and, under certain biophysical conditions, may reduce the capability of communities to cope with poverty.

    Abstract Protected areas can prevent forest loss, but their effects on forest fragmentation and forest regrowth are poorly understood. Furthermore, the importance of protected areas in shaping these forest spatial changes may depend on different socioeconomic drivers (e.g. population size, distance to cities, proportion of local people working in non-farm occupation), but the empirical evidence on such dependence is very scarce. Here, we used contra factual technics to assess whether biosphere reserves (n = 19) in the Mesoamerican biodiversity hotspot can reduce forest loss and fragmentation and promote forest regrowth during the period 2000–2020. We used satellite imagery and governmental data to assess the socioeconomic factors driving these changes. Particularly, using multimodel inference analysis, we tested whether higher non-farm occupation, combined with low demographic pressures, reduces forest loss and fragmentation and promotes forest regrowth. We found that reserves reduce forest loss and preserve less-fragmented configurations, however, they neither reduce fragmentation rate nor promote forest regrowth. Forest loss rate inside the reserves decreased as non-farm occupation enhanced and the density of rural settlements decreased. Therefore, promoting higher opportunities in non-farm economic activities and planning rural settlements distribution around reserves could help to increase the effectiveness of reserves for forest conservation.

    Abstract Protected areas are of paramount relevance to conserving wildlife and ecosystem contributions to people. Yet, their conservation success is increasingly threatened by human activities including habitat loss, climate change, pollution, and species overexploitation. Thus, understanding the underlying and proximate drivers of anthropogenic threats is urgently needed to improve protected areas' effectiveness, especially in the biodiversity-rich tropics. We addressed this issue by analyzing expert-provided data on long-term biodiversity change (last three decades) over 14 biosphere reserves from the Mesoamerican Biodiversity Hotspot. Using multivariate analyses and structural equation modeling, we tested the influence of major socioeconomic drivers (demographic, economic, and political factors), spatial indicators of human activities (agriculture expansion and road extension), and forest landscape modifications (forest loss and isolation) as drivers of biodiversity change. We uncovered a significant proliferation of disturbance-tolerant guilds and the loss or decline of disturbance-sensitive guilds within reserves causing a "winner and loser" species replacement over time. Guild change was directly related to forest spatial changes promoted by the expansion of agriculture and roads within reserves. High human population density and low nonfarming occupation were identified as the main underlying drivers of biodiversity change. Our findings suggest that to mitigate anthropogenic threats to biodiversity within biosphere reserves, fostering human population well-being via sustainable, nonfarming livelihood opportunities around reserves is imperative.
