地区水务局为改善土地排水系统提供赠款援助一直是英国农业支持的一个重要特征。这篇论文报告了一项研究，该研究旨在评估和解释农民对16个公共资助项目的收益的性质和比率，这些项目涉及英格兰中部的洪水缓解和动脉排水改善。总共对177名农民、880块土地和5500公顷土地进行了调查，收集了有关改善方案在排水状况、土地利用、耕作制度和绩效方面随时间变化的数据。实物数据被转换成标准化的企业和农场预算。特别注意评估草地生产力。58%的地区从中受益。效益吸收的最高值与土地利用变化、田间排水装置、草地氮肥使用量增加和草地管理变化有关。早期吸收与土地利用变化和农田排水有关。影响因素与田地、农场和农民变量的组合有关。表现最好的方案包括农民排水组织。得出了s形的总体吸收曲线，该曲线与“福利情景”的制定一起，可用于帮助预测对未来计划的吸收。
Grant aid for land drainage improvements by Regional Water Authorities has been an important feature of agricultural support in Britain. The paper reports a study undertaken to evaluate and explain the nature and rate of farmer uptake of benefits on sixteen publicly financed projects involving flood alleviation and improved arterial drainage in central England. A total of 177 farmers, 880 blocks of land, and 5500 hectares were surveyed, with data collected on the changes over time in drainage status, land use, and farming system and performance attributable to the improvement schemes. Physical data were converted into standardised enterprise and farm budgets. Particular attention was given to assessing grassland productivity. Benefits were perceived on 58% of the areas. The highest value of benefit uptake was associated with land-use change, field drainage installation, increased nitrogen use on grass, and changes in grass management. Early uptake was associated with land-use change and field drainage. Influencing factors related to a combination of field, farm, and farmer variables. The best performing schemes contained farmer drainage organisations. An S-shaped aggregate uptake curve was derived which, together with the formulation of ‘benefit scenarios’, could be used to help predict uptake on future schemes.
