In a forum letter, Miss Lee Kay Yan said that SMU's urban farming initiative will put land that would otherwise sit idle to good use ("Urban farming takes root at SMU", Jan 7). She added that when sufficiently well established, the site could also provide shelter and act as a natural corridor for indigenous birds and some animals. Miss Lee also suggested expanding SMU's urban farming idea island-wide. This includes setting aside a portion of the land in neighbourhood parks for the planting of vegetables and tropical fruit trees.
