城市农业有助于粮食安全和人类福祉，并与广泛的环境效益相关。在英国，城市农业的很大一部分发生在分配花园，这些是历史上重要的景观部分。然而，自世纪中期的高峰以来，分配土地的供应已大幅下降。在这里，我们研究的规模和性质的下降，使用GIS分析的历史Orchid Survey地图，涵盖10个英国城市地区从二十世纪世纪开始到现在。我们发现，从高峰到2016年，分配土地减少了65%，这一模式也反映在人均供应上，下降了62%，表明了案例研究地区的长期趋势，以及平均6%的城市人口的粮食供应土地的损失。我们还表明，粮食不安全风险最高的地区面临的配额关闭水平是最贫困地区的八倍。通过对以前分配土地的后续土地利用进行评估，我们发现47%的分配土地现在是城市基础设施的一部分，25%是其他形式的城市绿地。将这些绿地恢复为分配土地有可能满足我们案例研究区域居民对新分配土地的100%需求。我们的研究结果表明，虽然大量的城市农业用地已经失去了，恢复的机会存在很大的规模。
Urban agriculture contributes to food security and human wellbeing and is associated with a wide range of environmental benefits. In the United Kingdom, a substantial proportion of urban agriculture occurs in allotment gardens, and these are a historically significant part of the landscape. However, allotment land provision has declined significantly since its mid-twentieth century peak. Here, we examine the magnitude and nature of this decline using a GIS analysis of historic Ordnance Survey maps covering ten British urban areas from the beginning of the twentieth century to the present. We find there has been a 65% decline in allotment land from its peak to 2016, a pattern also reflected in per capita provision, which declined by 62%, demonstrating a long-term trend across the case study areas, and the loss of food provisioning land for an average of 6% of the urban population. We also show that the most at-risk areas for food insecurity have faced eight times the level of allotment closures than the least deprived areas. Assessing subsequent land-use of former allotments, we show that 47% of allotment land is now part of the urban built infrastructure, and 25% is other forms of urban greenspace. Restoration of these greenspace sites to allotments has the potential to meet up to 100% of the current levels of demand for new allotments by residents of our case study areas. Our results demonstrate that whilst a significant amount of urban agricultural land has been lost, opportunities for restoration exist on a substantial scale.
