“…Both Emberiza aureola and Rostratula benghalensis use paddy fields as their main habitat type. Rostratula benghalensis was shown to depend on fallow land in Japan and it underwent a drastic decline in Japan due to the loss of wet fallow fields after the 1990s (Katayama et al., 2020), indicating the importance of traditional ways of maintaining fallow fields being part of the ecological growth process.…”

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.

“…Such farmlands, especially the wet paddy farms, are not merely producing rice. Yet, they also support fish cultivation(agrofisheries), minimizing soil erosion, controlling floods, recharging groundwater, regulating ecosystem services, and maintaining biodiversity's [5]. Despite the importance of such farmlands and their indispensable contribution to the national food security and food self-sufficiency, land-use change is converting tremendous farmlands areas, particularly on Java Island.…”

Paddy fields are the most crucial agricultural land-use in Indonesia that supporting national food security. Such lands have been experienced a massive change in their dynamics, specifically in rice production home, West Java. Karawang paddy fields notably become the major victim of land-use change along with rapid economic growth, development, and population pressure. This study aimed to assess paddy fields’ conversion dynamic and how land-use change contributes to this issue in Karawang. Remote sensing techniques and satellite images were used for investigation across the Karawang Regency. Three kinds of satellite image datasets of Landsat 5 TM, Landsat 8 OLI, and Sentinel 2 during the periods of 2009, 2014, and 2019 were analyzed. The results revealed that land-use change impacted paddy fields conversion significantly. Karawang regency lost 16346.77 ha or 8.54 % of its paddy fields throughout the study period. Such farmlands declined by 8639.84 ha (4.51%) and 7706.93 ha (4.02%) between 2009 -2014 and 2014 to 2019, respectively. The conversion of paddy fields to build areas, including road infrastructures, is approximately 14536.21 ha, representing 57.98% of the total paddy fields converted. It concluded that paddy fields had faced massive conversion over the last ten years driven by conversion into buildup areas due to the increased land demand, i.e., residential, commercial, and industrial activities.

“…It is unclear whether, during fallow periods when pesticides are not applied, pesticide residues in soils (Gevao et al, 2000) can potentially have any lasting effect on aquatic invertebrates. This is particularly important when other animals, such as waterbirds, rely on aquatic invertebrates in flooded fallow fields for survival (e.g., Fujioka et al, 2001Fujioka et al, , 2010Katayama et al, 2020;Stafford et al, 2010).…”

Rice is one of the most important staple foods in the world, with irrigated rice paddies largely converted from natural wetlands. The effectiveness of rice fields in preserving species depends partially on management practices, including the usage of pesticides. Previous studies have focused predominantly on the cultivation period, leaving the potential effects of soil pesticide residues on organisms during the fallow periods underexplored. Other animals, such as waterbirds, also rely on aquatic invertebrates in flooded fallow fields for their survival. We investigated vertebrates and macroinvertebrates during cultivation and fallow periods in organic and conventional rice fields in Taiwan. The association of environmental factors with terrestrial and aquatic organisms was also analyzed. In total, 32,880 individuals from 144 invertebrate families and 381 individuals from 15 vertebrate families were recorded after nine samplings each in six organic and six conventional rice fields. The family richness and abundance of all invertebrates were higher in organic than in conventional fields during the cultivation period but were similar in fields under either agricultural practice during the fallow period. The differences in richness and abundance of terrestrial invertebrates between the two practices increased with progression of rice cultivation, while there was no difference in abundance of aquatic invertebrates during the fallow period. The richness and abundance of fish, amphibians, reptiles, birds, and migratory waterbirds were not statistically different between the two practices. Our study suggested accumulative effects of pesticides on suppressing terrestrial and aquatic invertebrates during the cultivation period, but no negative effects of soil pesticide residues on aquatic invertebrates during the fallow period. This comprehensive study provided a holistic picture of macroinvertebrate and vertebrate fauna, as well as the potential ramifications of pesticide usage, in a representative Southeast Asian rice paddy ecosystem. Future studies should compare rice fields with natural wetlands to better assess how to capitalize on agroecosystems for biodiversity conservation.
