“…The irrigation conditions of cultivated land have improved and farmers can have more cultivated land. From 1995 to 2015, the cultivated land irrigation area in the PRB increased from 46.30 km 2 to 89.86 km 2 , with an annual average growth rate of 4.70% [ 82 ]. Reclamation has severely damaged the wetland ecological environment.…”

Wetland ecosystems play one of the most crucial roles in the world. Wetlands have the functions of ecological water storage, water supply, and climate regulation, which plays an indispensable role in global environmental security. The Pumqu River Basin (PRB) is located in an area with extremely vulnerable ecological environment, where climate change is obvious. Understanding wetland distribution, changes and causes in the PRB are of great importance to the rational management and protection of wetlands. Using the Landsat series satellite images, wetlands of this area in 2000, 2010, and 2018 were extracted. The results showed that (1) there were obvious regional differences in wetland types and their distribution patterns in the basin. Wetlands were mainly distributed in areas with slopes less than 12° and at elevations between 4000 m and 5500 m. (2) During the past 20 years, the wetland area in the basin decreased, and the changing trend of wetlands was different. Palustrine wetlands decreased tremendously, riverine and lacustrine wetlands first decreased and then increased, while floodplain wetlands first increased and then decreased. Palustrine wetlands were reclaimed to cultivated land, but the proportion of reclamation is small. (3) Climate dominated wetland changes in the PRB. The changes in riverine and lacustrine wetlands were mainly affected by the warm-season average temperature, the change in palustrine wetlands was mainly related to the annual precipitation and the warm-season average temperature, and the change in floodplain wetlands was related to the warm-season precipitation. To achieve sustainable development, the government plays a guiding role and actively formulates and implements wetland protection policies, such as restricting or prohibiting grazing on wetlands, which play an important role in wetland protection and restoration.

“…The OSL dating process involved collecting 4 samples from the sedimentation section, which were treated in a dark room and purified of organic matter and carbonates through a combination of hydrogen peroxide and hydrochloric acid. Quartz grains were extracted from the samples through etching with hydrofluoric acid [16].…”

Detailed field investigations in the Yellow River-Huangshui River Valley(YHV) uncover stratigraphic sections of soil sediments intercalated with multiple layers of slack water deposit(SWD). In-depth analysis of palaeoflood sediment sections in the YHV: Combination of detailed observational measurements, stratigraphic delineation, sampling, optical stimulated luminescence(OSL) dating, grain size analysis, and End-Member(EM) analysis. Non-Parametric method resolves 7 EMs components with distinct source and depositional dynamics from the palaeoflood sediment sequence in 3 sections. Analysis of soil sediment stratigraphic units in the YHV reveals mixed superposition of multiple EM components. Macroscopic characteristics, physical and chemical properties indicate occurrence of paleofloods in 28.9 ka-18.4 ka phases, with SWD formed from long-distance transport of surface sediment carried by river floods and sandy sediment from river diffuse beaches under hydrodynamic action. EM analysis of full sample size reflects diverse sediment dynamics of the YHV. Findings hold significant implications for disaster prevention and mitigation in the region.

“…In this sense, farmers often overestimate the frequency of unfavourable weather events and might confuse changes in rainfall with changes in the sensitivity of the cropping system (Traore et al 2015). For example, in drought years, farmers with less irrigated cropland could not obtain adequate water resources, leading them to be more likely to perceive a decrease in precipitation (Wang et al 2020).…”

Farmers’ perception of climate change is crucial in adaptation intention and process. However, farmers’ perceptions may not be timely, accurate and systematically consistent with the direction and significance of observational records. Although some research compared farmers’ perceptions and climate data, little attention has been paid to comprehensibly analyse both data sources discrepancies based on empirical studies results. By combining bibliometrics and a systematic review approach, we identify which approaches are used to compare perceived and observed data, how both patterns have been mutually evolved, which factors determine their (in)consistency, and if their accordance and robustness affect farmers’ adaptive capacity. We analyse a portfolio of 147 papers collected from the Scopus library catalogue since 2000. The bibliometric analysis was coupled with an exploratory analysis of 98 papers selected from the original portfolio. The literature is extensive, fast-growing, and spans several disciplines. We identify four consolidated research lines: i) perceived risk and farmers’ adaptive capacity nexus, ii) crop vulnerability due to temperature increase and erratic rainfall patterns, iii) forecasting use and influence in farmers’ decisions, and iv) climate change awareness conditioning farmers’ profiles. Nonetheless, we observe some research gaps: 1) a conceptual mismatch in ‘normal pattern’ or ‘drought’ meaning, 2) poor or limited data from meteorological stations, 3) overlook or oversimplification of local knowledge in describing perception, 4) farmers’ memory weaknesses to keep track of climate alterations, and 5) a geographical dissonance in favour of Global South regions. Our science-metric study also reveals some research questions to be consolidated: Can the perception of extreme events increase climate change awareness? Can greater awareness reduce discrepancy with observed data? How do heuristics and socio-psychological filters influence farmers’ awareness and interpretation of climate data? We suggest putting major efforts into reinforcing these research lines as part of a novel domain-dependent trend to reduce the discrepancy.
