I am an Argentine architect and urban planner. Soon will be traveling to China to participate in the Turenscape Academy international workshop on sponge cities. It is incredibly sad to know that Professor Yu will not be there with us and I would like to express my deepest condolences for his passing. Urban and landscape planning has lost one of its most brilliant exponents. We will all miss him from all corners of the world

我是一名阿根廷建筑师和城市规划师。不久后，我将前往中国参加土人设计学院关于海绵城市的国际研讨会。得知俞教授无法与我们同在，这令人无比悲痛，我想对他的离世表达我最深切的哀悼。城市和景观规划领域失去了一位最杰出的代表。世界各地的我们都会怀念他。
