世界各地的牧民社区在粮食和饲料生产方面面临着复杂的挑战。初级生产系统受到压力,营养选择正在发生变化,发展与农业之间的关系正在发生深刻的变化。在气候和土地使用变化的压力越来越大的情况下,东非农牧系统正接近土地退化的临界点。迫切需要以证据为导向的可持续土地管理干预措施,以扭转支持粮食和水安全的自然资源退化。然而,一个关键的障碍是缺乏高空间分辨率的土壤健康数据,其中收集每个社区的此类信息超出了他们的能力。在这种情况下,我们测试了是否可以通过参与和公民科学之间的边界协调计划来弥合这些数据差距。主要产出包括:由社区主导的手持式土壤扫描仪试验,其中强调了在这方面使用这一技术的一系列积极效益和实际挑战,并确定了一些潜在的解决方案;以及在小流域社区环境中有针对性的土壤有机物和养分状况数据集。结果表明,如果能够解决实际挑战,便携式土壤扫描仪技术的使用有可能填补关键的知识空白,从而通过当地响应的农民和社区决策来提高对土地退化威胁的抵御能力。
Pastoralist communities worldwide face complex challenges regarding food and feed productivity. Primary production systems are under stress, nutritional choices are changing and the relationship between development and agriculture is undergoing profound transformation. Under increasing pressure from climate and land use change, East African agro-pastoral systems are approaching a tipping point in terms of land degradation. There is an urgent need for evidence-led sustainable land management interventions to reverse degradation of natural resources that support food and water security. A key barrier, however, is a lack of high spatial resolution soil health data wherein collecting such information for each individual community is beyond their means. In this context, we tested whether bridging such data gaps could be achieved through a coordinated programme at the boundary between participation and citizen science. Key outputs included a community-led trial of a hand-held soil scanner, which highlighted a range of positive benefits and practical challenges in using this technology in this context, with identification of some potential solutions; and a targeted soil organic matter and nutrient status dataset in a small catchment-based community setting. The results show that if the practical challenges can be resolved, use of portable soil scanner technology has the potential to fill key knowledge gaps and thereby improve resilience to the threat of land degradation through locally responsive farmer and community decision-making.
