“…Many studies have shown that rubber and palm oil plantations support only limited eco‐functional groups compared with natural forests (Koh & Wilcove, 2008; Zhang et al., 2017). However, few studies have explored the biodiversity differences between traditional agricultural land and natural forests in tropical regions, although agricultural land could harbor different functional groups from natural forests and potentially act as “other effective area‐based conservation measures” in the entire conservation system (Hou et al., 2022). For example, when paddy fields are flooded at different frequencies after harvest, they can be used by different eco‐functional waterbird species (Strum et al., 2013).…”

Biodiversity in tropical regions is facing threats from agricultural expansion and intensification. Therefore, a promising future for local ecosystem conservation depends not only on traditional protected areas but also on well‐managed agricultural landscapes. In this study, we compared the ecological traits of bird species in paddy fields outside of protected areas and natural forests within the protected areas of Xishuangbanna, southern China. There were 148 species in total, of which 98 were in forests and 55 in paddy fields. The abundance of birds in paddy fields was 176 per kilometer, which was much higher than the 60 per kilometer in forests. There were 26 law‐protected species observed, half of which were found in each habitat. The main functional groups living in nature reserves are invertivores and frugivores, whereas paddy fields provide habitats for aquatic predator and granivore bird species. Our results indicate that paddy fields act as a refuge for wetland and grassland bird species when natural wetlands disappear, highlighting the urgent need to focus more on wetland protection and eco‐friendly agricultural schemes at the landscape scale in future conservation policies.

“…Based on bird survey data, assessing changes in HS is a common method to determine priority areas for bird conservation, and has been used to determine conservation priorities in arable land and coastal wetlands in China (Hou et al, 2022;Xia et al, 2017). The priorities established by previous studies primarily re ect the spatial aggregation of birds (Amano et al, 2018).…”

Context: Poyang Lake (PYL) and Dongting Lake (DTL), as the two largest freshwater lakes in China, play crucial roles in biodiversity conservation and water resource allocation. However, due to the combined impacts of human activities and climate change, the timing of their early dry season (EDS) has significantly changed in recent years, leading to ecological and economic issues. It is essential to conduct priority identification of wetland restoration, because of the limitations of funds, policies, and manpower. Objectives: We determine 1) a priority identification framework based on habitat suitability changes and weight data of migratory birds; 2) priority areas for habitat restoration of PYL and DTL wetlands; and 3) habitat restoration efficiency in priority areas. Methods: We combined habitat suitability data for migratory birds with studies of early dry season to identify priority restoration areas. We use three landscape pattern indices and spatial autocorrelation analysis to investigate the distribution pattern of key areas and evaluate the efficiency of habitat restoration. Results: The area of PYL wetland of very high, high, low, and very low priorities for wetland restoration is 90.19, 463.48, 404.47, and 2498.42 km2, respectively. And that of DTL wetland is 109.61, 381.46, 331.68, and 1809.27 km2, respectively. The PYL wetland exhibits a high degree of fragmentation in low-priority areas. In contrast, the DTL wetland exhibits fragmentation in both high-priority and very high-priority areas. Conclusion: The high priority and very priority areas of these two wetlands should be the focus of restoration efforts as they are the most efficient for habitat restoration. The result is of great significance for the conservation of resources and biodiversity in wetlands.

“…Spatial multi-criteria analysis (MCA) combines complex multidimensional data analysis with the direct involvement of stakeholders, considers multiple criteria, and integrates multiple layers of diverse spatial information for identifying priority areas (Raaijmakers et al, 2008;Li et al, 2020). Previous research has integrated social, economic, and political considerations by applying spatial MCA to identify priority areas for bird conservation (Hou et al, 2022), soil-water conservation areas (Ahmed et al, 2023), ecological conservation and restoration (Chen et al, 2023), flood risk mitigation (Rehman et al, 2022), and conservation planning (Brum et al, 2017).…”

Over the past four decades, China has invested $298 billion in cultivated land consolidation (CLC), making a substantial contribution to increased agricultural production and enhanced food security despite rapid urban expansion and cultivated land encroachment. However, in the absence of a quantitative, spatial evaluation of CLC potential that engages local stakeholders including farmers, community, and decision-makers, the scope for systematic planning to guide and influence the prioritization, effectiveness, and efficiency of CLC for achieving enduring benefits for agricultural productivity and sustainability is limited. In this study, we used a knowledge co-production approach with spatial multi-criteria analysis (MCA) for evaluating CLC potential in Jiangsu Province and identifying priority areas with the participation of stakeholders. We identified key priority areas and considerations for ensuring CLC implementation for supporting the transition to more productive and sustainable agricultural systems including 7 priority types across 813 townships. 41.82 % of the areas were targeted for resource consolidation, 33.83 % for pattern consolidation, and 9.84 % for utilization consolidation, with the remaining 14.51% for combined consolidation based on multiple criteria. While 686 townships with low and very low CLC potential were incorporated into the CLC planning as protection and development priority types. These spatially explicit results can inform regional prioritization and targeting investment in CLC projects with a high level of buy-in from stakeholders. The methodology and findings of this study can inform innovation in systematic spatial planning with stakeholders for CLC across China and help manage the trade-offs between urbanization and food security.
