“…Hence the waterfowl distribution is often more closely linked to wider landscape features than to local aspects of field management (Maeda 2001;Elphick et al 2010). During the wet season open-billed storks are breeding in colonies mostly near larger wetlands, whereas in the dry season the birds are roaming freely (Sundar 2006).…”

Despite wetland conversion to intensive rice production Central Thailand remains a center for wetland biodiversity in Southern Asia. Fauna inhabiting rice fields (many species perform important ecosystem services) are, however, increasingly threatened by pesticide uses. In Ayutthaya and Ang Thong Provinces 40 conventionally and 31 organically managed farms were visited to investigate how abundance and diversity of aquatic fauna in rice fields relate to pesticide regimes. In the dry and wet seasons fields were surveyed for plankton, aquatic macro-invertebrates, fishes, and waterfowl. Using multivariate statistics pesticide variables and biophysical field parameters (determined in a previous study) were assessed as potential predictors of abundance/diversity of faunal groups. Effects of pesticide regimes on aquatic fauna were nontrivial. Phytoplankton was lowered under exposures to herbicides and natural insecticides. Zooplankton (except amoeboids) was unaffected or increased on pesticide-exposed fields, probably suffering lower predation. Biophysical aspects partly explained abundance/diversity of aquatic insects, but abundance/diversity was generally higher on fields treated with natural rather than synthetic insecticides. Fishes and waterfowl tended to be less abundant on fields exposed to synthetic insecticides and herbicides. Detailed findings may interest agro-ecologists, medical entomologists, and conservation biologists. Further research incorporating wider landscape aspects and including pesticide-free reference sites is suggested.

“…El cultivo de arroz inundado es considerado como hábitat de aves acuáticas y como humedal artificial, ya que ofrece un hábitat de forrajeo y refugio contra los depredadores similar a los ecosistemas naturales, ayudando a la conservación de las especies (86,87). Las aves no son una plaga para el cultivo de arroz, pues solo 10% de las aves que se encuentran en el cultivo son consumidoras del mismo y de estas solo algunas causarían un aparente daño al cultivo.…”

El uso eficiente del agua determina el futuro del cultivo de arroz en Colombia frente a los tratados de libre comercio, ya que es un factor que condiciona el área sembrada, el rendimiento de la cosecha y los costos de producción, además de su sostenibilidad en el tiempo. Por lo tanto, se presenta una revisión de las tecnologías desarrolladas a nivel mundial enfocadas al ahorro del agua en el cultivo de arroz en condiciones aeróbicas y anaeróbicas. Se resaltan tecnologías alternativas que superan al sistema convencional en rendimiento y en la cantidad de arroz cosechado por metro cúbico de agua invertido. En la reflexión para Colombia, se destacan aspectos importantes para la construcción de la agenda de investigación y la apropiación social de las tecnologías alternativas con miras a la optimización del recurso hídrico en el cultivo de arroz; se recomienda priorizar el arroz aeróbico y la medición efectiva del consumo de agua, indispensable para controlar su uso, planear, dirigir y entender cómo estas tecnologías alternativas conducen a la recuperación de la inversión de los agricultores y a la rentabilidad del cultivo.Palabras clave: Arroz, tecnologías, uso eficiente del agua, aeróbico, campo inundado. AbstractWater use efficiency, given that it conditions the sown areas, yield and production costs, as well as its sustainability, determines the future of rice production in Colombia against the FDA. This paper presents a review of the globally developed technologies for water saving in rice production under aerobic and anaerobic conditions. The authors highlight alternative technologies that surpass the conventional system in terms of yield and harvest per cubic meter of water used. In the reflection for Colombia, the authors highlight important features for the research agenda and the social appropriation of alternative technologies with a view to optimizing water resources usage for rice production. Recommendations include the prioritizing of aerobic rice and the effective measurement of water consumption, which is indispensable for its use, and for planning, directing, and understanding how these alternative technologies can lead to the recovery of the investment made by agricultural workers and crop profitability.

“…Water birds in the family Rallidae generally prefer to nest and roost in low bushes around water environments, whereas for foraging, they favor the areas surrounding waters or paddy field environments, bamboo groves, and thickets. Because of safety considerations during the breeding season, they will choose breeding sites in the bushes surrounding water environments and select water weeds as a nesting material [31][32][33][34][35][36][37][38][39]. Therefore, in addition to the use of the water in the farm pond itself for foraging, nesting, and breeding of birds, the vegetation cover around the bank is also a source of food and a hiding place for birds [31,33,40].…”

Identifying Farm Pond Habitat Suitability for the Common Moorhen (Gallinula chloropus): A Conservation-Perspective Approach

et al. 2018

The purpose of this study was to establish a habitat-suitability assessment model for Gallinula chloropus, or the Common Moorhen, to be applied to the selection of the most suitable farm pond for habitat conservation in Chiayi County, Taiwan. First, the fuzzy Delphi method was employed to evaluate habitat selection factors and calculate the weights of these factors. The results showed that the eight crucial factors, by importance, in descending order, were (1) area ratio of farmlands within 200 m of the farm pond; (2) pond area; (3) pond perimeter; (4) aquatic plant coverage of the pond surface; (5) drought period; (6) coverage of high and low shrubs around the pond bank; (7) bank type; and (8) water-surface-to-bank distance. Subsequently, field evaluations of 75 farm ponds in Chiayi County were performed. The results indicated that 15 farm ponds had highly-suitable habitats and were inhabited by unusually high numbers of Common Moorhens; these habitats were most in need of conservation. A total of two farm ponds were found to require habitat-environment improvements, and Common Moorhens with typical reproductive capacity could be appropriately introduced into 22 farm ponds to restore the ecosystem of the species. Additionally, the habitat suitability and number of Common Moorhens in 36 farm ponds were lower than average; these ponds could be used for agricultural irrigation, detention basins, or for recreational use by community residents. Finally, the total habitat suitability scores and occurrence of Common Moorhens in each farm pond were used to verify the accuracy of the habitat-suitability assessment model for the Common Moorhen. The overall accuracy was 0.8, and the Kappa value was 0.60, which indicates that the model established in this study exhibited high credibility. To sum up, this is an applicable framework not only to assess the habitat suitability of farm ponds for Common Moorhens, but also to determine whether a particular location may require the implementation of conservation practices. Furthermore, the findings in this research can provide useful information to all relevant stakeholders involved in the implementation of wildlife-habitat conservation and restoration at farm ponds.
