原文摘要

Urban agriculture (UA) remains an important but unevenly governed part of urban food systems in many rapidly urbanizing cities of the Global South. Existing research has documented its contribution to food access, livelihoods and urban resilience, but less attention has been given to locally grounded pathways for supporting UA in African cities. This paper examines the current landscape and possible future trajectories of UA in Dar es Salaam, Tanzania. Using an exploratory qualitative case-study and policy-analysis approach, the study draws on targeted literature and document review, a policy and regulatory scan, and 52 key informant interviews conducted between April and September 2025 with municipal actors, urban farmers and food-system practitioners. The findings show that UA is valued for household food supplementation, small-scale income generation and fresh-food provisioning, particularly through short-cycle vegetable production close to consumers. However, it remains shaped by tolerated informality, insecure land access, fragmented regulation, contamination risks, weak institutional coordination and pressure on peri-urban land. Based on the combined analysis, the paper proposes five evidence-informed trajectories: managed river-corridor cultivation; sacks, buckets and roofs for dense-ward micro-production; institutional land clusters; peri-urban foodshed belts with circular-resource hubs; and small-scale aquaculture and insect-based feed systems. These pathways are not presented as tested feasibility models, but as differentiated options requiring further technical, environmental, spatial and economic assessment. The paper argues that the future of UA in cities such as Dar es Salaam is unlikely to depend on a single large-scale model, but on risk-sensitive and institutionally grounded forms of support that align food access, livelihoods, public health and urban planning.

一片叶子完成基因体检 国内首款华南型黄瓜育种芯片落地青岛

青岛市农科院联合山东极智生物科技发布华南型黄瓜专用5K液相育种芯片V1.0,是国内首款针对华南型黄瓜遗传背景设计的专用育种芯片,筛选5300多个核心位点(含78个功能前景位点),整体检出率97.57%。依托40份核心种质资源全基因组重测序构建,芯片把瓜类回交转育周期从5至6代约三年缩短到2至3代、一年半,育种周期整体有望缩短一半。这是国产分子工具替代外来方案、支撑种业自主可控的关键一步,也说明AI与基因数据结合正在把传统育种推向精准化。
