Riparian zones are vital transitional habitats that bridge the gap between terrestrial and aquatic ecosystems. They support elevated levels of biodiversity and provide an array of important regulatory and provisioning ecosystem services, of which, many are fundamentally important to human well-being, such as the maintenance of water quality and the mitigation of flood risk along waterways. Increasing anthropogenic pressures resulting from agricultural intensification, industry development and the expansion of infrastructure in tropical regions have led to the widespread degradation of riparian habitats resulting in biodiversity loss and decreased resilience to flooding and erosion. Considering climate change and its associated effects on freshwater systems, the need to build resilience and adaptive capacities is pertinent. This has prompted the need to protect existing riparian habitats and the implementation of solutions to restore these degraded habitats to recover their functional capacity. This systematic map will aim to identify and collate existing literature on approaches for riparian restoration implemented in tropical regions and identify what indicators have been used to measure outcomes for biodiversity and human well-being. The resulting collation of evidence will help to identify current knowledge gaps and inform the direction of future research.
To address the aims of this systematic map, a search of pre-identified bibliographic databases will be undertaken using a set string of search terms. In addition to this, a grey literature search will be conducted using Google Scholar and by searching for references using specialist websites. All literature that is gathered will be screened by title, abstract and full text using a two-phase screening process which adheres to a pre-determined eligibility criteria. Data will then be coded from the collated group of articles using a pre-designed data coding sheet. Heterogeneity will likely be present in the data; therefore, studies will be grouped appropriately based on the restoration strategy implemented and, on the type of outcome measured. These will be presented as sub-groups. A narrative synthesis of map findings will be produced, this will outline the distribution and frequency of restoration interventions, and outcomes measured, and will highlight evidence gaps to direct future research.
河岸带是至关重要的过渡栖息地，它弥合了陆地和水生生态系统之间的差距。它们支持着更高水平的生物多样性，并提供一系列重要的调节和供给生态系统服务，其中许多对人类福祉至关重要，例如维持水质和减轻水道沿线的洪水风险。热带地区农业集约化、工业发展和基础设施扩张导致的人为压力不断增加，已致使河岸栖息地广泛退化，造成生物多样性丧失，以及对洪水和侵蚀的抵御能力下降。考虑到气候变化及其对淡水系统的相关影响，增强恢复力和适应能力的需求十分迫切。这促使人们需要保护现有的河岸栖息地，并实施相关解决方案来恢复这些退化的栖息地，以恢复其功能。本系统综述旨在识别和整理关于热带地区实施的河岸恢复方法的现有文献，并确定用于衡量生物多样性和人类福祉成果的指标。由此产生的证据整理将有助于识别当前的知识空白，并为未来研究的方向提供参考。
为实现本系统综述的目标，将使用一组预先确定的搜索词对预先选定的书目数据库进行搜索。除此之外，还将使用谷歌学术进行灰色文献搜索，并通过专业网站搜索参考文献。所有收集到的文献将通过两阶段筛选过程，根据标题、摘要和全文进行筛选，该过程遵循预先确定的纳入标准。然后将使用预先设计的数据编码表从整理好的文章组中对数据进行编码。数据中可能存在异质性；因此，将根据实施的恢复策略以及所测量的结果类型对研究进行适当分组。这些将作为子组呈现。将对综述结果进行叙述性综合，概述恢复干预措施的分布和频率以及所测量的结果，并突出证据空白以指导未来的研究。
