The Agricultural Stream Syndrome (AgSS): Re-igniting healthy resilience through restoration

人类对地球生态系统的影响现在如此普遍，以至于联合国宣布2021-2030年为生态系统恢复十年，这是建立在全球越来越多的人接受的基础上的，即退化的生态系统尚未完全恢复，人类驱动的气候变化已将我们置于紧急状态。鉴于溪流和河流生态系统是生物多样性和人类影响的热点，它们的状况代表了其周围的景观。因此，STREAMS作为探索恢复延迟和成功背后的机制的模型系统。从理论上讲，恢复的目标是恢复积极的抵抗和弹性机制，使所需的属性在没有持续干预的情况下自我延续。然而，复苏继续显示出延迟。我的研究一直表明，由于不匹配的恢复操作使它们处于不健康的状态，降级的数据流仍然具有弹性。采取多样化和包容性的办法，在建立一个新的框架-农业溪流综合症--方面取得进展，将把退化的生物和非生物属性结合起来，以加快确保生态系统全面恢复的努力。为了将恢复的重点放在加速生态系统恢复上，该计划的长期愿景是开发一种解决退化和恢复农业溪流的新范例，在这里称为农业溪流综合症。该计划将使当地和土著知识系统与不同的研究方法结合起来，包括实地调查以捕捉河岸-河流和生态系统功能关系，数据综合以提取和赋予基于特征的社区属性并评估全球恢复文献，以及在实地实施空间换时间研究方法，将空间上不同的地点作为长期生态时间序列的代理。我们将利用这一计划作为在现实世界中进行更长期、更大规模的河流恢复实验的一步。在接下来的五年里，我将授权和培训HQP来测试负面抵抗和弹性机制的假设(Sensu Barrett等人)。2021年)为延迟的生态系统恢复奠定了基础。我们将对河岸植物和溪流中的底栖大型无脊椎动物进行实地调查，以量化跨系统的关系，应用功能特征数据来赋予这些关系，并产生关于什么恢复行动(S)具有潜在的点燃和维持期望的相互作用的假设。该计划几乎完全致力于该地区的农业景观，因此有必要采取公平、多样化和包容性的研究方法，让定居者和土著知识系统、当地社区、从业者、政府和行业都作为研究伙伴参与研究，以实现短期目标和实现长期愿景。

Human impacts on the Earth's ecosystems are now so pervasive that the UN has declared 2021-2030 the Decade of Ecosystem Restoration, building on the growing global acceptance that degraded ecosystems are not fully recovering and human-driven climate change has placed us in a `code red' state of emergency. Given that streams and river ecosystems serve as hotspots of biodiversity and human impacts, their condition is representative of their surrounding landscapes. As such, streams serve as model systems explore mechanisms behind restoration delay and success. Theoretically, the goal of restoration is to restore positive resistance and resilience mechanisms such that desired properties are self-perpetuating without ongoing interventions. However, recovery continues to show delays. My research has consistently shown that degraded streams remain resilient due to mismatched restoration actions that keep them in an unhealthy state. Taking a diverse and inclusive approach, progress towards a new framework - the Agricultural Stream Syndrome - will bring together the biotic and abiotic attributes of degradation to accelerate efforts to ensure full ecosystem recovery. To pivot the focus of restoration on accelerated ecosystem recovery, the long-term vision for this program is to develop a new paradigm for addressing degraded - and restoring - agricultural streams, herein called the Agricultural Stream Syndrome. This program will engage local and Indigenous knowledge systems alongside diverse research methodologies that include field surveys to capture riparian-instream and ecosystem function relationships, data syntheses to extract and confer trait-based community properties and assess the global restoration literature, and, to implement a space-for-time study approach in the field which will engage spatially distinct sites as proxies for long-term ecological time series. We will use this program as a step towards longer-term, larger scale stream restoration experiments on the ground, in real world contexts. In the coming five years, I will empower and train HQP to test the hypothesis that negative resistance and resilience mechanisms (sensu Barrett et al. 2021) underpin delayed ecosystem recovery. We will conduct field surveys on riparian plants and in-stream benthic macroinvertebrates to quantify cross-system relationships, apply functional trait data to confer these relationships and generate hypotheses on what restoration action(s) have the potential to ignite and sustain desired interactions. Working almost entirely on agricultural landscapes in the region, this program necessitates an equitable, diverse and inclusive approach to the research, engaging Settler and Indigenous knowledge systems, local communities, practitioners, government and industry all as research partners to achieve the short-term objectives and work towards the long-term vision.
