First rotation Perennial crops for sustainable citiesUrban agriculture (UA) is increasingly recognised as a strategy for more sustainable food production. UA can also increase the health and wellbeing of urban residents, reduce warming and air pollution in cities, and provide habitat for wildlife. Evidence suggests that small-scale UA can be as productive as conventional farming, and typically uses fewer synthetic fertilisers. However, considerations must still be given to all aspects of resource use involved in UA to ensure it is truly sustainable.Perennial crops such as fruit trees and shrubs may offer multiple benefits for reducing resource use in UA. They don't need to be replanted annually, leading to less soil erosion, and providing carbon storage. They may require less labour and could offer biodiversity benefits by providing food and year-round shelter for wildlife. Perennial crops may also be more resilient to pollination and other resource limitations due to shunting of resources between growing seasons.Aims and methods:1. Conduct a systematic review of the pros/cons of perennial crops in UA, identifying knowledge gaps;2. Work with growers, using citizen science, to collect data on resource use (water, chemical,labour, financial) in perennial, annual and mixed plantings in UA;3. Use questionnaires to identify attitudes towards perennial crops in UA e.g. the willingness togrow and consume such crops (including resilient and less commonly grown crops)and the perceived benefits and barriers to use;4. Conduct pollination deficit experiments to assess the resilience of perennial crops to pollinator limitation.

第一轮多年生作物用于可持续城市城市农业（UA）越来越被认为是一种更可持续的粮食生产战略。UA还可以提高城市居民的健康和福祉，减少城市的变暖和空气污染，并为野生动物提供栖息地。有证据表明，小规模普遍获得农业可以与传统农业一样高产，而且通常使用较少的合成肥料。然而，仍然必须考虑到普遍获得服务所涉资源使用的所有方面，以确保其真正可持续，果树和灌木等多年生作物可为减少普遍获得服务的资源使用提供多种好处。它们不需要每年重新种植，从而减少土壤侵蚀，并提供碳储存。它们可能需要更少的劳动力，并可以通过为野生动物提供食物和全年庇护所来提供生物多样性好处。多年生作物也可能更适应授粉和其他资源限制，由于资源分流之间的生长季节。对普遍获得服务中多年生作物的利弊进行系统审查，查明知识差距;2.与种植者合作，利用公民科学，收集关于UA多年生、一年生和混合种植的资源使用（水、化学品、劳动力、财政）的数据;3.使用调查问卷查明普遍获得服务国家对多年生作物的态度，例如，种植和消费这类作物（包括具有复原力和不太常见的作物）的意愿，以及使用这类作物的预期效益和障碍;进行授粉不足实验，以评估多年生作物对传粉者限制的适应能力。
