Analyzing vulnerability and adaptation to soil and water loss is an important part of the study on the human–environment relationship in the Loess Plateau. It has also provided a new perspective for studying the farmers’ adoption behavior of soil and water conservation technology in the soil erosion area of the Loess Plateau. Based on the Turner vulnerability framework, this paper constructs a household-scale index system of soil and water loss vulnerability in the Loess Plateau and evaluates the soil and water loss vulnerability in the Loess Plateau using the field survey data of the Loess Plateau applied entropy method. Finally, we use the binary logistic model to estimate the impact mechanism of farmers’ soil erosion vulnerability on farmers’ adoption behavior of soil and water conservation technology. The main conclusions are as follows: (1) In the total sample, susceptibility > exposure > adaptability, whereas in the Shaanxi and Gansu subsample, susceptibility > adaptability > exposure. The Ningxia subsample was similar to the total sample. For each index, Ningxia > Gansu > Shaanxi; (2) The exposure and susceptibility of soil and water loss have a positive impact on farmers’ adoption behavior of soil and water conservation technology, and natural capital has a positive impact on farmers’ adoption behavior of soil and water conservation technology. Physical capital has a positive impact on farmers’ adoption behavior of biological measures. Financial capital has a negative impact on farmers’ adoption behavior of biological measures and farming measures. Social capital has a positive impact on farmers’ adoption behavior of engineering measures and biological measures; (3) Overall, the marginal effect of the adoption behavior of farmers’ soil and water conservation techniques, adaptability > susceptibility > exposure. Therefore, it is necessary to strengthen the monitoring of soil and water loss, encourage the government and farmers to respond in time, and reduce the losses caused by soil erosion. Enriching the capital endowment of farmers, breaking through the endowment restriction of farmers’ adoption of soil and water conservation technology.

The Loess Plateau, China, has long been suffering from serious soil erosion. About 2000 years ago, larger areas were used for grain production and soil erosion was thus becoming severe with increase in human activity. Severe soil and water loss led to widespread land degradation. During the past decades, great efforts were made in vegetation restoration to reduce soil erosion. However, the efficiency of vegetation restoration was not as satisfactory as expected due to water shortage. China initiated another state-funded scheme, the `Grain-for-Green' project in 1999, on the Loess Plateau to reduce soil erosion and improve land quality. However, the control of soil erosion effectively by land-use modification raised problems. In this paper, the lessons and experiences regarding soil and water conservation in the Loess Plateau in the past decades are analysed first. Urgent problems are then elaborated, such as the contradiction between land resource and human population, shortage of water both in amount and tempospatial distribution for vegetation growth, weak awareness of the problems of soil conservation by local officials, and poor public participation in soil and water conservation. Finally, suggestions regarding soil and water conservation in the Loess Plateau are given. In order to control soil erosion and improve vegetation, a scientific and detailed land-use plan for the Loess Plateau has to be made, in the first instance, and then planning for wise use of water resources should be undertaken to control mass movement effectively and to improve land productivity. Methods of improving public awareness of environmental conservation and public involvement in vegetation rehabilitation are also important.

In recent years, under the background of global climate change, extreme rainstorm occurs frequently in the loess plateau, causes a series of soil damage, was difficult to predict. Therefore, it is a great significance to study the rule of extreme rainstorm for the soil erosion in the loess plateau. Based on the daily rainfall data of 56 meteorological stations and global sea surface temperatures (SST) data in the last 60 years, the effects of El Niño on extreme rainstorm were studied by using empirical orthogonal function (EOF), wavelet transform, and other statistical methods.

Soil erosion and socio-economic interacts with each other. Soil and water loss destroys land resources, causes non-point source pollution, affects the recycling and utilization of water resources, worsens the water environment, and even causes natural disasters such as collapse, landslides, and debris flows. Soil erosion affects regional socio-economic development. On the one hand, economic and social development has caused a sharp increase in people’s demand for the development and utilization of natural resources, which has increased the occurrence of soil and water loss; on the other hand, economic and social development has promoted people’s understanding of soil erosion and soil and water conservation, enabling people to consciously change their production and lifestyle, and having sufficient funds to invest in soil and water conservation and reduce soil erosion.

<p>The Loess Plateau of China is known for its severe soil and water loss problems. Terracing is one of the most important soil and water conservation measures there. Our understanding of the effects of terraces on soil and water conservation and its mechanism is limited by observation data on runoff and soil erosion as well as the influences from local environmental characteristics. In this study, we applied a physically-based distributed hydrological model (Integrated Hydrology Model, InHM) to an experimental terrace in Wangmaogou watershed of the Loess Plateau, and validated it with the measured soil water content. Our results suggested that terrace construction can substantially reduce runoff by changing the flow direction, especially during heavy rainfall events. This reduction in runoff would be greatly attenuated when ridges are damaged due to lack of maintenance. Under the rainfall intensity of 120 mm/h, compared with hillslope, a well-maintained terrace could reduce runoff by 100%, while the terrace without ridges could only reduce 28% runoff. Besides, ridges not only prevented water from flowing out of platforms, but also helped maintain the risers from terrace failure by decreasing about 20% of the saturation rate at the risers. Our results also emphasized the importance of evaporation, which could make up to 15% of the total water loss even during the rainfall events. Given the effects of terraces on water conservation, it is essential for the land use management of the Loess Plateau to take into account of the terracing approach, as well as a good maintenance of ridges.</p>

Based on the research of soil erosion and soil and water conservation in karst areas in China in recent years, the status and progress of soil erosion and soil and water conservation in karst areas in China are discussed. The results show that the soil and water loss in the karst area mainly has two types of soil erosion: surface soil erosion and underground soil erosion. Soil and water loss management in karst areas mainly adopts measures to adjust land use structure, increase vegetation coverage, carry out slope-to-ladder construction, and promote clean energy applications. Different governance models should be adopted for different landform types, different landform parts, different slopes, and different levels of rocky desertification in karst areas.

The streamflow has declined significantly in the coal mining concentrated watershed of the Loess Plateau, China, since the 1970s. Quantifying the impact of climate change, coal mining and soil and water conservation (SWC), which are mainly human activities, on streamflow is essential not only for understanding the mechanism of hydrological response, but also for water resource management in the catchment. In this study, the trend of annual streamflow series by Mann-Kendall test has been analyzed, and years showing abrupt changes have been detected using the cumulative anomaly curves and Pettitt test. The contribution of climate change, coal mining and SWC on streamflow has been separated with the monthly water-balance model (MWBM) and field investigation. The results showed: (1) The streamflow had an statistically significant downward trend during 1955–2013; (2) The two break points were in 1979 and 1996; (3) Relative to the baseline period, i.e., 1955–1978, the mean annual streamflow reduction in 1979–1996 was mainly affected by climate change, which was responsible for a decreased annual streamflow of 12.70 mm, for 70.95%, while coal mining and SWC resulted in a runoff reduction of 2.15 mm, 12.01% and 3.05mm, 17.04%, respectively; (4) In a recent period, i.e., 1997–2013, the impact of coal mining on streamflow reduction was dominant, reaching 29.88 mm, 54.24%. At the same time, the declining mean annual streamflow induced through climate change and SWC were 13.01 mm, 23.62% and 12.20 mm, 22.14%, respectively.
