Investigating the Water Balance for Sustainable Agriculture Water Management in Prince Edward Island

该项目将评估爱德华王子岛地表水和地下水平衡与气候变化的关系，以证明补充灌溉的潜力。目前，政府实施了一项暂停措施，禁止为高容量威尔斯的农业灌溉供应发放额外的许可证。这符合卡文迪什农场的利益，实际上也符合整个省的利益，因为它产生了可信的数据，可用于指导政府考虑如何根据新的《水法》管理灌溉。PEI受气候变化的影响，在降水量，时间，强度和空间分布。降雨情景的变化，特别是在生长季节，对马铃薯的产量和质量产生了不利影响，因为所需的水量无法在正确的时间供植物吸收。本研究旨在探讨气候变化下PEI的水量平衡，以评估利用补充灌溉来科普气候变化的可行性。本研究的目的是：1）研究气候变化对水平衡和可用性的影响，2）验证补充灌溉以满足作物水分需求的潜力，3）评估补给和排放模式，4）检查地下水开发潜力，以实现农业水资源的可持续管理。这项研究将为可持续水资源管理提供新的知识基础。根据作物需要适时合理用水，通过确保水资源的可持续性，具有提高农场盈利能力的巨大潜力。

This project will evaluate the fluctuations in surface and groundwater balance of Prince Edward Island (PEI) in relation to climate change to testify the potential for supplement irrigation. Currently there is a government imposed moratorium in place which prohibits additional permits being issued for agricultural irrigation supply by high capacity wells. It is in the interest of Cavendish Farms, and indeed the province as a whole to generate credible data that could be used to guide government as it considers how to manage irrigation under the new Water Act. PEI is affected by the climate change in term of precipitation amounts, time, intensity, and spatial distribution. Changes in the rainfall scenarios especially during growing season are adversely affecting the potato yield and quality, as required amounts of water is not available for plant uptake at right time. This studyis designed to investigate the water balance of PEI under the changing climate to evaluate the feasibility of using supplemental irrigation to cope with the changes caused by climate change. The objectives of this research are to: 1) study the impact of climate change on the water balance and availability, 2) testify the potential for supplemental irrigation to meet the crop water requirements, 3) evaluate the recharge and discharge patterns, and 4) examine the groundwater development potential for sustainable management of water for agriculture resources. This research will provide a new knowledge base for sustainable water management. Wise use of water based on crop need, at right time, has a strong potential to improve farm profitability by ensuring sustainability of water resources.
