到2050年,农业面临着养活90亿人口的巨大全球挑战。这就意味着需要农业的全面集约化。作为提高农业生产力和可持续性的明确愿景,生态集约化正在获得势头。如何调整生态集约化以使撒哈拉以南非洲(SSA)的小农农业系统受益仍然是一个主要问题。在本研究中,我们开发了以生态集约化技术为依托,适应不同农场类型的小农农业发展路径。这项研究依赖于与南非Ha Lambani的农业专家和小农的多年合作,从而确定了农民群体。我们分析了与农民进行的40次深度半结构化访谈,从而确定了农业模式和制约因素。我们介绍了对挑战和制约因素的农业系统分析如何有助于确定特定的生态系统服务并将其与适当的生态集约化选择联系起来。我们的结论是,基于专家的农民分类提供了农业系统异质性的更情境化的代表,其中量身定制的生态集约化技术可以在提高农业生产力方面发挥重要作用。除了这个群落外,它还强调需要将农民类型异质性作为目标生态集约化的一个强有力的决策参数。
Agriculture faces an enormous global challenge of feeding nine billion people by 2050. This means a comprehensive intensification of agriculture is required. Ecological intensification is gaining momentum as a clearly defined vision for increasing agriculture productivity and sustainability. How ecological intensification could be tailored to benefit smallholder farming systems in sub-Saharan Africa (SSA) remains the major question. In this study, we develop pathways relying on ecological intensification technologies and suiting different farm types of smallholder agriculture. This study relies on multiyear engagements with agricultural experts and smallholder farmers in Ha Lambani, South Africa and leads to the identification of farmer groupings. We analyse 40 in-depth semi-structured interviews with farmers which leads to the identification of farming patterns and constraints. We present how farming systems analysis of challenges and constraints helps to identify and link specific ecosystem services with suitable ecological intensification options. We conclude that the expert-based classification of farmers offered a more contextualized representation of farming system heterogeneity, where tailored ecological intensification technologies could play a major role in improving agricultural productivity. Beyond this community, it emphasizes the need to consider farmers type heterogeneity as a strong decision parameter for targeting ecological intensification.
