“…Several geospatial analyses across the Amazon basin have shown that Indigenous Peoples’ lands play a fundamental role in buffering against deforestation and forest degradation ( 29 , 66 – 69 , 71 ). In addition, data collected over a 34-year period found that natural vegetation conversion in Brazil was lower in protected areas and areas governed by Indigenous Peoples than on other lands ( 72 ). These current trends are reinforced by archaeological data on human alteration of Amazonian tropical forests over the past 5000 years.…”

Primates, represented by 521 species, are distributed across 91 countries primarily in the Neotropic, Afrotropic, and Indo-Malayan realms. Primates inhabit a wide range of habitats and play critical roles in sustaining healthy ecosystems that benefit human and nonhuman communities. Approximately 68% of primate species are threatened with extinction because of global pressures to convert their habitats for agricultural production and the extraction of natural resources. Here, we review the scientific literature and conduct a spatial analysis to assess the significance of Indigenous Peoples’ lands in safeguarding primate biodiversity. We found that Indigenous Peoples’ lands account for 30% of the primate range, and 71% of primate species inhabit these lands. As their range on these lands increases, primate species are less likely to be classified as threatened or have declining populations. Safeguarding Indigenous Peoples’ lands, languages, and cultures represents our greatest chance to prevent the extinction of the world’s primates.

“…Our field investigation showed that dozens of in situ conserved populations, including the three wild rice species, grow well; however, the community type and the proportion of different land cover types of these conserved populations seem to be similar to those of populations that disappeared ( Supplementary Figure S6 ). The reason is that human disturbance is effectively avoided by physical barriers, such as fences or wire entanglements, or mitigated by the buffer zone around the conserved populations ( Gonçalves-Souza et al, 2021 ). For the un-conserved populations, those with a small area of natural vegetation exhibit high extinction rates ( Figure 3 ).…”

Effects of land use change on population survival of three wild rice species in China since 2001

Land use change stemming from human activities, particularly cropland expansion, heavily threatens the survival of crop wild relatives that usually occur nearby or scatter in farming systems. Understanding the impacts of land use change on wild populations is critical in forming the conservation decision-making of wild relatives. Based on the investigations on the population survival of three wild rice species (Oryza rufipogon, O. officinalis, and O. granulata) in China over the past 40 years (1978–2019), the effect of land use change during the past 20 years (2001–2019) on the natural populations of the three species was examined using the land use type data of satellite-based Earth observations (data from GlobCover). From 1978 to 2019, the number of populations (distribution sites) of the three wild rice species had decreased by 65–87%, mainly because of the habitat destruction or disappearance caused by human-induced land use change. The three wild rice species display different habitat preferences, resulting in specific land use types surrounding their populations. In the recent 20 years, although the surrounding community composition of the wild rice population has been relatively stable, the surrounding vegetation cover area of the survived populations was significantly more extensive than that of the extinct ones (p < 0.05). These findings suggest that habitat vegetation plays a “biological barrier” role in the survival of wild populations through resisting or mitigating the disturbing impact of land use change on wild populations. This study provides not only direct guidelines for the conservation of wild rice but also new insights into the mechanisms underlying the influence of land use change on wild populations.

“…National parks can offer herders salaried work to participate in conservation programs or tourism, achieving a win-win situation since they increase their revenue and safeguard grasslands protection. This can also involve experienced indigenous people in the management of PAs, which international experience values (e.g., Garnett et al, 2018 ; Gonçalves-Souza et al, 2021 ). Also, ecological migration can be a solution, but this option requires appropriate production means and sufficient infrastructure.…”
