“…In our interviews, landowners stated they obtained the soil used for urban fill from adjoining land. Pond owners also explained that they used excavated soil for nearby developments or sold it to the construction markets as Hara et al (2008) also reported. If we assume 1 m of fill for all urban developments on the 2010 map (Fig.…”

“…This type of land development was adaptive to the inherent flood conditions in this continental delta (Hara et al 2005). The landscape change was also influenced by the cost and availability of fill materials (Hara et al 2008). In our interviews, landowners stated they obtained the soil used for urban fill from adjoining land.…”

“…Hara et al (2008) reported that soil availability was a major constraint in many monsoonal Asian continental deltas, such as that on which Bangkok is built. These deltas were first mainly used for floating rice cultivation because of the favorable hydro-geographical and climatic conditions (Takaya 1987).…”

“…Hence, whereas many ecologists have studied conservation of waterbirds and other wildlife species in large-scale natural wetlands, including mangrove areas and tidal flats in this area (e.g., Duckworth et al 2002;Round 2006;Mohd-Azlan and Lawes 2011;Chaiyarat and Eiam-Ampai 2014), researchers may put much less value on studies of biodiversity in urban-agricultural landscape areas. However, Hara et al (2008) reported that these urban-rural mosaic wet landscapes have been long-lasting, some for more than 30 years. Also, urbanization is still proceeding in many areas along with population increases in fringe areas (Murakami et al 2005), inducing a continuous dynamic of new urban-rural mixed landscapes.…”

This study examined the spatial relationships between various types of wetland and the distribution of Asian openbills (Anastomus oscitans) as an indicator species in a peri-urban industrial area of Bangkok. We (1) mapped the study area by using a time series of aerial photographs combined with field validations, (2) conducted a 2-year line census of Asian openbills in the field, (3) interviewed local farmers and residents about Asian openbill populations and spatial distributions, and (4) conducted an overlay analysis to statistically identify land-use factors related to spatiotemporal changes in the Asian openbill population and distribution. We found that the number of ponds increased from 1980 to 1999 and then decreased from 1999 to 2010, but the remaining ponds were relatively temporally stable in their numbers and volumes. Paddy fields were primarily replaced by aquaculture ponds, and excavated soil was used as fill in adjoining built-up areas. The number of coconut, banana, mango and other trees planted around the ponds increased during the period, providing Asian openbill habitat. The openbills fed in the remaining paddy fields, and the simultaneous existence of various rice cultivation stages in the area provided a stable year-round source of food. Overall, the results indicated that this expanding urban-rural mosaic landscape could include further spatial distribution of Asian openbills in the future. This study of Asian openbills reveals just one example of the ecosystem services provided by developments creating pond-fill landscapes, and the methods used may be applicable in other similar continental delta regions.

“…As a result, its canals have gradually deteriorated and become neglected by urbanites [17,18]. New urbanization, i.e., housing estates led by a road network, have been developed through land filling and damaging the existing irrigation systems, currently in the peri-urban area [19,20]. These canal deteriorations not only generate environmental problems but also create social conflicts [19].…”

This paper discusses the deterioration of indigenous irrigation system traditionally developed in the past to serve the peri-urban agricultural lands that have been affected by rapid urbanization in the Bangkok Metropolitan Region. The study is based on data collection from mapping, field survey and interview analyses and identifies current canal deteriorating conditions in four categories: filled, covered, narrowed and shallow, and normal. The findings reveal that different types of canal deteriorations are associated with their private ownership. A typology of land configurations of urban and non-urban land uses along private canals is pointed out in order to understand their relation with canal deterioration types. Caused by urbanization, the degradation of the existing canal networks has provoked conflicts between local farmers and new proprietors, especially real estate developers. Such canal deterioration essentially reduces their ability to convey a water supply to feed agricultural lands, consequently leading to the discontinuation of land use for agriculture and its eventual transformation into urban developments.
