摘要

摘要最近的调查显示,全球城市人口正在加速增长。因此,对食品需求的增加推高了城市居民的总体生活成本。为了减轻生活成本的增加,城市居民越来越多地从农业活动中找到慰藉。城市农业活动激增之际,气温、降雨模式和一般天气条件都发生了长期变化。尽管许多研究人员提出了城市农业活动增加的证据,但总结城市农业气候变化问题的综合文献仍然很少。这项研究回顾了有关气候变化对撒哈拉以南非洲城市城市农业经营影响的文献。采用叙述性综述的方法来总结和综合研究结果,并为未来的研究提出建议。该综述使用了关键术语“城市农业”、“城市农业“、“气候变化”、“城郊农业”和“城市农业生产”来搜索数据库中的相关文献:Scopus、开放获取期刊目录、科学网、谷歌学者和学术搜索(EBSCO)。这些关键词的选择是基于作者对城市农业和气候变化的专业理解。回顾的文献一致认为,气候变化影响城市农业从生产到加工、储存和分销。这项研究还证实,气候变化影响的程度和程度因地区而异。因此,适应和缓解战略应当针对具体情况,而不是普遍适用。这一点很重要,因为非洲是一个气候多样的大陆,因此撒哈拉以南非洲一个城市面临的气候变化影响可能与其他地区其他城市不同。制定了一个简化气候变化对撒哈拉以南非洲城市农业依赖家庭影响的框架。更具体地说,这一框架被推荐给那些参与减轻气候变化后果以及实现粮食和营养安全的城市农民和政策制定者。作者还推荐了这个框架,以揭示气候变化对城市农业影响的知识,并为未来的研究指明方向。这项工作增加了城市农业依赖家庭在气候变化领域日益增长的知识。

Climate change and its impact on urban agriculture in Sub-Saharan Africa: A literature review
Abstract Recent surveys have shown that the global urban population is increasing at an accelerated rate. As a result, the associated increased demand for food items has pushed up the overall cost of living for urban dwellers. To mitigate this increased cost of living urban dwellers increasingly find solace in agricultural activities. This surge in urban agricultural activities comes at a time characterized by long term shifts in temperatures, rainfall patterns and general weather conditions. While many researchers have presented evidence of increased urban agricultural activities, there remains a paucity of integrated literature that summarizes climate change issues on urban agriculture. This research reviewed literature on the influence of climate change on urban agricultural operations in sub-Saharan African cities. A narrative review approach was employed to summarize and synthesize findings and make recommendations for future research. The review employed the key terms ‘urban farming’, ‘urban agriculture’, ‘climate change’, ‘peri-urban agriculture’, and ‘urban agricultural production’ to search relevant literature indexed in databases: Scopus, Directory of Open Access Journals, Web of Science, Google Scholar and Academic Search (EBSCO). The choice of these keywords was informed by the authors’ specialist understanding of urban agriculture and climate change. There is consensus among the reviewed literature that climate change affects urban agriculture from production to processing, storage, and distribution. This study also established that the extent and magnitude of climate change impacts differ from one region to another. Therefore, adaptation and mitigation strategies ought to be context specific and not universally applicable. This is important because Africa is a climatologically diverse continent so that the impact of climate change faced by one sub-Saharan African city may be different from that for other cities in other regions. A framework that simplifies the effects of climate change on urban agriculture-dependent households in sub-Saharan Africa was produced. More specifically, this framework is recommended to those urban farmers and policymakers that are involved in mitigating the consequences of climate change as well as achieving food and nutritional security. The authors also recommend this framework for unpacking the knowledge of the influence of climate change on urban agriculture as well as exposing directions for future research. This work adds to the growing body of knowledge in the domain of climate change on urban agriculture-dependent households.
