“…The ecological restoration measures performed by humans mainly include grazing prohibition, hunting prohibition, artificial seeding, and artificial weather intervention. Thus, these measures have only a local direct effect to small extents as a mending of the bare land patches and an acceleration of natural evolution to assist the system to regain its resilience [31]. The ecosystem's restoration and improvement of vegetation on a large scale are basically determined by nature's influencing and nourishing role [32].…”

How climate change and human activities drive the evolution of the regional environment and where the quality of ecosystems improve or decline over time have become widespread concerns. In this study, we took the Three-River-Source (TRS) region of the Qinghai–Tibet Plateau as a case, aiming to identify and quantify the contribution of the natural and anthropogenic factors to the ecosystem changes over the past years from 1980 to 2018 using the methods of remote sensing and spatial statistical analysis. Based on the land cover map interpreted by reference to satellite remote sensing imagery data, we defined the Ecological Restoration Area Proportion (ERAP) as the bare land patch decrement to indicate the ecologically restored quantity in space. Assembling the restoration project information, we digitalized and vectorized the ecological Restoration Intensity (RI) including the spatial range and temporal duration. Combining the ERAP and the net primary productivity (NPP), which indicates the quantity and quality of ecosystems, respectively, the ecological asset Index (EAI) was developed and calculated. Having integrated the datasets of the vegetation monitoring, climatic factors, geographical factors, and human activities, we performed multi-variable analysis of the attribution of how the change in the EAI, the NPP, and the EAI have been affected by these factors together. The NPP of the middle and eastern parts of the TRS region has improved the most, as the average growth rate of NPP reached approximately 2.5 kg C/m2/10a. Due to such dynamic pattern, we found that human-induced re-vegetation has made limited contributions in our multi-regression model as the variance explained by the RI merely amounts to 4.4% to 8.8%, while the changes were mostly dependent on the regional temperature and the precipitation which contributed over 45% to the ecological restoration on average. It was summarized that “climate-help” overwhelms “human act” in such alpine grassland ecosystem. The regression results for the different aspects of the ERAP and NPP demonstrated that the ecological restoration project helped most in regard to ecosystem quality improvement rather than the restored ecosystem quantity. Our study has developed a comprehensive assessment methodology that can be reused to account for more ecological asset. The case is an example of an alpine ecosystem in which the success of ecological restoration needs favorable climatic conditions as supporting evidence for the nature-based solution.

“…Floodplains are among the most threatened ecosystems in which the annual flood cycle critically impacts productivity (Islam and Braden, 2006). Threats are severe in lagoon floodplains because the hydrological regime is highly dynamic and impacted by salt water (López-Juambeltz et al, 2020).…”

This article describes a combination of the driver-pressure-state-impact-response (DPSIR) framework and the logical framework approach (LFA) to develop water management strategies for a lagoon floodplain in Thailand. The DPSIR framework identified the cause-effect relationship between water and anthropogenic activities. LFA developed management strategies based on a systematic and logical approach. DPSIR analysis for the issue of water shortages for irrigated areas revealed the need for income from agriculture is a major driver, as indicated by agricultural development policy. The driver exerted pressure on increasing irrigation water demand, which increased the risk of a water shortage. The impact of water shortage was indicated by loss of farmer income. Existing responses led to inadequate problem-solving, for example, the promotion of mixed farming. Using data captured from DPSIR analysis for LFA analysis, proposed strategies to address the root causes of “ineffective irrigation water allocation” focused on improving (1) the performance of rotating irrigation systems; (2) monitoring water allocation; and (3) water use efficiency. The strategies developed using the combined DPSIR framework and LFA are effective because: (1) this method provides insight into complex water systems; (2) the strategies are developed logically to solve the problem at its root cause; and (3) there is intensive stakeholder participation and in-depth study of the area. This method is a helpful tool for developing a management strategy for a complex water system and is suitable for application by decision-makers. Stakeholder verification is required for future research to ensure that the strategies are appropriate and capable of being implemented.

“…Juncus sp., is an angiosperm with owers belonging to the botanical family Juncaceae, commonly known as Juncus. This genus is widely distributed throughout the world and is found in a variety of habitats, including swamps, meadows, and pastures [50]. This species is known for its tall, green, or reddish stems, which can reach a height of 1.5 meters [51].…”

The objective of this study was to evaluate the mechanical performance of geotextiles made from natural bers of Syagrus coronata (Mart.) Becc., Thypha domingensis, and Juncus sp. The geotextiles were treated with waterproo ng resin and exposed to biodegradation for 120 days to understand their stress and strain behavior. The geotextiles was treated with colorless wood waterproo ng resin by Hydronorth® to make it less permeable, delay the degradation process, and consequently increase the material's resistance to climatic variables. Subsequently, the geotextiles was subjected to natural degradation on slopes covering an area of 10m². Samples of the exposed material to the degradation processes were collected every 30 days. The ndings reveal that the examined bers, following treatment with waterproo ng resin, exhibit the capability for extended utilization in the eld, with Thypha ber outperforming the other tested bers. These results hold signi cant potential for the incorporation of natural bers in endeavours related to environmental conservation.
