Human needs like food and clean water are directly related to good maintenance of healthy and productive soils. A good understanding of human impact on the natural environment is therefore necessary to preserve and manage soil and water resources. This knowledge is particularly important in semi-arid and arid regions, where the increasing demands on limited water supplies require urgent efforts to improve water quality and water use efficiency. It is important to keep in mind that both soil and water are limited resources. Thus, wise use of these natural resources is a fundamental prerequisite for the sustainability of human societies. This Special Issue collects 15 original contributions addressing the state of the art of soil and water conservation research. Contributions cover a wide range of topics, including (1) recovery of soil hydraulic properties; (2) erosion risk; (3) novel modeling, monitoring and experimental approaches for soil hydraulic characterization; (4) improvement of crop yields; (5) water availability; and (6) soil salinity. The collection of manuscripts presented in this Special Issue provides more insights into conservation strategies for effective and sustainable soil and water management.

AbstractClimate change is one of the most significant and complex challenges facing the world's economies. The necessity to enlarge the knowledge base regarding climate change and its impacts and to design efficient policies is widely accepted by the scientific community, the decision makers and the general public. This special issue, which will be published in two parts in the current and subsequent issue of Environment and Development Economics, is a selection of papers related to the topic of the international workshop on ‘The Economics of Climate Change and Sustainability’ organized by the Economics Department of the University of Bologna in April 2018. The papers in this special issue cover a wide range of climate-change-related topics, which include endogenous growth and overlapping generation models; climate-related financing and green bonds; demographics; location decisions; technology diffusion; quantitative relationships and experimental approaches. We hope that this special issue will provide some new insights into the economics of climate change and help to identify new directions for future research.

AbstractClimate change is considered to be one of the most significant and complex challenges facing the world in the twenty-first century. As such, it is essential to increase the knowledge base regarding climate change and how best to address its impacts through efficient policies. This special issue, which is divided into two parts – published in the previous and current issues of Environment and Development Economics – is a selection of papers related to ‘The Economics of Climate Change and Sustainability’, the topic of an international workshop organized by the Economics Department of the University of Bologna in April 2018. The papers in this special issue cover a wide range of climate-change-related topics, including endogenous growth and overlapping generation models; climate-related financing and green bonds; demography; location decisions and technology diffusion; quantitative relationships and experimental approaches. They aim at providing new insights into the economics of climate change and help to identify new directions for future research.

Soil erosion risk assessment is an essential foundation for the planning and implementation of soil and water conservation projects. The commonality among existing studies is that they considered different indicators (e.g., rainfall and slope) in order to determine the soil erosion risk; however, the majority of studies in China neglect one important indicator, namely the slope aspect. It is widely accepted that the vegetation and distribution of rainfall differs according to the different slope aspects (such as sunny slope and shady slope) and these attributes will accordingly influence the soil erosion. Thus, existing studies neglecting this indicator cannot reflect the soil erosion well. To address this problem, a flexible soil erosion risk assessment method that supports decision makers in identifying priority areas in soil and water conservation planning was developed in the present study. Firstly, in order to verify the impact of the slope aspect on soil erosion, field investigations were conducted, and its impact on the characteristics of the community in the study area was analyzed. Secondly, six assessment indicators were selected, including slope gradient, precipitation, NDVI, land use, soil texture and slope aspect. Next, a developed multi-criteria decision analysis (MCDA) method based on the Choquet integral was adopted to assess the soil erosion risk. The MCDA method, combining objective data with subjective assessment based on Choquet integral, could solve the weight problem encountered when using the quantitative method. The parameters required can be modified according to the soil erosion types, assessment scales, and data availability. The synergistic and inhibitory effects among the soil erosion parameters were also considered in the assessment. Finally, the soil erosion risk results in the Xinshui River watershed revealed that more attention should be paid to the slope of farmland and grassland during the planning and management of soil and water conservation projects. The methodology used in the current study can support decision makers in planning and implementing soil and water conservation measures in regions with different erosion types.

It’s not possible to have relied on the large irrigation programmes only to solve Maharashtra’s recurring and acute water scarcity. In recent years, the state has recognized soil and water conservation activities as a potential option for agricultural development in rainfed, semi-arid areas. Further government has clubbed all the schemes regarding soil and water conservation run by different departments of the state government under the umbrella of Jalyukt Shivar Abhiyan. The results revealed that the Jalyukt Shivar Abhiyan activities had a significant impact on groundwater recharge, access to groundwater and hence the expansion in irrigated area. It has been found to alter crop patterns, increase crop yields and crop diversification and thereby provided enhanced employment and farm income. Local villagers were at the forefront of the programme, not just in decision- making, but also in actual execution and monetary contributions. In a nutshell Jalyukt Shivar Abhiyan has not resulted in physical output but it gave support to the ecological and socio-economic progress of the beneficiaries. Looking at all the above results, Jalyukt Shivar Abhiyan seemed to be one of the basic strategy for doubling the farmer’s income in rainfed and semi-arid regions of Maharashtra

Soil erosion is a key problem in Ethiopia in view of tropical climate, lack of vegetation, and landscape relief. Therefore, soil and water conservation (SWC) measures have been practiced, but their impacts on soil loss have not been estimated adequately. The RUSLE modeling was applied using satellite imageries, ASTER GDEM, rainfall, and soil data to estimate total annual soil loss for a 100 km2 hilly and highly populated area in Ethiopia. Soil loss decreased in the Damota districts from 21 to 13 million tons from 2000 to 2020. Similarly, the average annual soil loss decreased by 36%. Very slight-risk areas (< 5 t ha−1 yr−1) increased from 42.66 to 53.72%, and very high-risk areas (> 50 t ha−1 yr−1) decreased from 12 to 5%. Soil and water conservation measures showed an important implication against soil erosion through improved land cover and landscape greenness. However, still, the rate of soil erosion is high compared to the soil loss tolerance of 1–6 t ha−1 yr−1 for the Ethiopian highlands.
