Predicting the impact of climate change on crop water footprint using CMIP6 in the Shule River Basin, China

Quantitatively predicting the impacts of climate change on water demands of various crops is essential for developing measures to ensure food security, sustainable agriculture, and water resources management, especially in arid regions. This study explored the water footprints (WFs) of nine major crops in the middle and downstream areas of Shule River Basin, Northwest China, from 1989 to 2020 using the WF theory and CROPWAT model and predicted the future WFs of these crops under four emission and socio-economic pathway (SSPs-RCPs) scenarios, which provides scientific support for actively responding to the negative impacts of climate change in arid regions. Results indicated: (1) an increasing trend of the overall crop WF, with blue WF accounting for 80.31–99.33% of the total WF in the last 30 years. Owing to differences of planting structure, water-conservation technologies, and other factors, the multi-year average WF per unit area of crops was 0.75 × 104 m3 hm−2 in downstream area, which was higher than that in midstream area (0.57 × 104 m3 hm−2) in the last 30 years; therefore agricultural water use efficiency in the downstream area was lower than that in the midstream area, implying that the midstream area has more efficient agricultural water utilization. (2) an initial increase and then decrease of crop WFs in the study area under SSP1-2.6, SSP2-4.5, and SSP5-8.5 scenarios by the end of the century, reaching their peak in 2030s which was higher than that from 1989 to 2020; with the maximum growth rates in the midstream area ranging from −0.85% in SSP5-8.5 to 5.33% in SSP2-4.5 and 29.74% in SSP5-8.5 to 34.71% in SSP2-4.5 in the downstream area. The local agricultural water demand would continue to increase and water scarcity issues would be more severe in the next 10–20 years, affecting downstream areas more. Under the SSP3-7.0 scenario, crop WF values of the midstream and downstream regions will be 2.63 × 108 m3 and 4.22 × 108 m3 in 2030, respectively, which is significantly higher than those of other scenarios and show a long-term growth trend. The growth rate of the midstream and downstream regions will reach 44.71% and 81.12%, respectively, by the end of this century, so the local agricultural water use would be facing more strain if this scenario materializes in the future. Therefore, the Shule River Basin should encourage development of water-saving irrigation technologies, adjust the planting ratio of high water consuming crops, and identify other measures to improve water resource utilization efficiency to cope with future water resource pressures.

Preparation and properties of a metal-organic frameworks polymer material based on Sa-son seed gum capable of simultaneously absorbing liquid water and water vapor

Atmospheric water harvesting (AWH) technology has attracted significant attention as an effective strategy to tackle the global shortage of freshwater resources. Work has focused on the use of hydrogel-based composite adsorbents in water harvesting and water conservation. The approaches adopted to make use of hygroscopic inorganic salts which subject to a “salting out” effect. In this study, we report the first use of modified UIO-66-NH2 as a functional steric cross-linker and Sa-son seed gum was used as polymeric substrate to construct super hygroscopic hydrogels by free radical copolymerization. The maximum water uptake on SMAGs (572 cm3·g−1) outperforms pure UIO-66-NH2 (317 cm3·g−1). Simultaneously, our first attempt to use it for anti-evaporation applications in an arid environment (Lanzhou, China) simulating sandy areas. The evaporation rate of the anti-evaporation material treated with 0.20 % super moisture-absorbent gels (SMAGs) decreased by 6.1 % over 64 h period under natural condition in Lanzhou, China. The prepared material can not only absorb liquid water but also water vapor, which can provide a new way for water collection and conservation technology. The design strategy of this material has wide applications ranging from atmospheric water harvesting materials to anti-evaporation technology.

Optimal Allocation of Water Resources in Canal Systems Based on the Improved Grey Wolf Algorithm

Xinjiang is located in the arid region of northwestern China, and agriculture accounts for an absolute share of total water use. Resource-based, engineering, structural, and managed water shortages coexist. Therefore, it is of great significance to vigorously develop water conservation technology and improve the efficiency of water transmission and distribution in canal systems. This research aims at addressing the problems of difficult manual regulation and the overall optimization of the final canal system, low-water-resource utilization efficiency, and management efficiency. Taking the branch-double two-stage canal system of Dongfeng branch canal in Mangxiang, Jinghe irrigation district, as a case study, and the rotation irrigation group and irrigation duration as decision variables, canal distribution is modeled with the goal of minimizing seepage losses. The improved grey wolf algorithm combined with particle swarm optimization is used for the first time and compared with the traditional grey wolf algorithm, genetic particle swarm optimization fusion algorithm, and northern goshawk algorithm. The results show that (1) on the basis of meeting the water discharge capacity and water demand requirements of the canal system, the diversion time of the water distribution scheme obtained by using the improved grey wolf algorithm is shortened from 11 d to 8.91 d compared with the traditional empirical water distribution scheme. (2) The improved grey wolf algorithm converges to the optimal value within 10 generations compared to the remaining methods, and the total water leakage is reduced from 16.15 × 104 m3 to 11.75 × 104 m3. (3) The number of gate adjustments is reduced, and the canal gates are opened and closed at the same time within each rotational irrigation group. The grey wolf algorithm improved by its combination with particle swarm has stronger optimization ability and convergence, which can better meet the requirements of efficient water resource allocation in irrigation canal systems, as well as a high application value.

Explaining drivers of farmers’ willingness for early adoption of enhanced irrigation technologies: case of Tunisia

The objective of this paper is to identify the influencing factors of farmers’ willingness for early adoption of enhanced irrigation technologies in Tunisia. We estimate a multinomial logit model with data from 931 farmers in Central (Chebika) and Northern (Fernana) of Tunisia. Regression results reveal that early adoption is positively influenced by levels of extension service quality, trust in farmers’ associations and extension agents, farmer’s perception towards the innovation, credit access, and off-farm income. However, it is negatively affected by market access issues, risk aversion, and age. Risk, trust, and perception towards technology are important factors in driving early adoption decision. The findings imply that farmers training on water conservation technologies, financial support for innovation adoption, awareness of young farmers about the opportunities of agricultural innovation, incentives to farmers’ associations in order to improve their market access, and inclusive participatory approaches during technology generation and transfer are all accelerators of early adoption speed of innovations by farmers.

Enhancing crop yield and conserving soil moisture through mulching practices in dryland agriculture

Dryland agriculture requires the efficient utilization of water resources and the implementation of water-conserving technologies. Mulching is a water conservation practice used in arid land areas to preserve soil moisture, control temperature, and minimize soil evaporation rates. Organic mulching minimizes soil deterioration, enhances organic matter, and boosts the soil’s ability to retain water. Mulching can help keep moisture in the root zone, allowing plants to receive water for extended periods. Mulching with composted yard waste led to higher soil nutrient levels, including phosphorus (P), potassium (K), calcium (Ca), and organic matter when compared to uncovered soil. Under plastic mulch, soluble nutrients such as nitrate (NO3−), ammonium (NH4+), calcium (Ca2+), magnesium (Mg2+), potassium (K+), and fulvic acid are released as organic matter decomposes, enhancing the soil’s nutrient availability. Mulching has several advantages for dryland agriculture, such as reducing soil water loss, soil erosion, weed growth, water droplet kinetic energy, and competition for nutrients and water with nearby fields. This review article aimed to demonstrate the effectiveness of ground mulching in water conservation. This is particularly important in arid regions where agricultural sustainability is at risk due to drought, heat stress, and the inefficient use of limited water resources during the cropping season. Ground mulching is essential for minimizing surface evaporation and hence decreasing water loss. This review research thoroughly examines the advantages of organic and synthetic mulches in crop production, as well as their use in the preservation of soil and water resources.

Agri‐mat and grass mulch effect on crop biomass yield in sandy loam and loam soils

AbstractThe role of agri‐mat mulch as a soil and water conservation technology for improved and sustainable plant production has not been explored. The aim of the study was to investigate the effects of agri‐mats and grass mulch on crop biomass yield of maize and spinach under sandy loam and loam soils. The following five mulch treatments were established in two sites (Durban with loam soil and Pretoria with sandy loam soil) during the 2017/18 and 2018/19 planting seasons: (a) full agri‐mat mulch cover (100%AG), (b) half agri‐mat mulch cover, (c) bare (control), (d) six tons of grass mulch per hectare (6t.GM), and (e) three tons of grass mulch per hectare. Crop growth parameters such as number of leaves, leaf length, plant height, and crop biomass yield were measured in both planting seasons. The results indicate that the crop biomass yield (both spinach and maize) was higher under 100%AG treatment compared to other mulching treatments followed by 6t.GM in the Pretoria site. For the Durban site, the highest crop growth parameters and biomass yield for both spinach and maize was recorded under the 100%AG treatment. The 100%AG treatment produced 33% more spinach biomass yield during the 2018 growing season in Durban compared with the 6t.GM treatment, with no percentage differences in the 2019 growing season. In Pretoria, there was a 20% (2018) and 32% (2019) difference in spinach biomass yield between the highest and second‐highest performing treatments. As hypothesized, agri‐mats can effectively improve crop biomass yields in semiarid and humid agro‐ecological zones with different soil types.

Purpose This study aims to explore the potential of Islamic climate finance in Indonesia and to map Islamic climate finance based on Islamic finance instruments, both commercial and social. Design/methodology/approach The analysis was conducted in Jakarta, Indonesia, between October 2022 and June 2023. This study adopted a qualitative interpretive approach in two phases. The first phase was desk-based research which focused on document analysis such as official documents, scientific publications, non-governmental organization publications and company reports in Indonesia. This analysis was conducted to identify significant milestones in developing green and eco-friendly finance that used Islamic financial instruments in Indonesia. The second phase consisted of interviews with essential Islamic climate finance project actors, such as green sukuk publishers, zakat and waqf collection agencies, stakeholders, capital market regulators, Shariah supervisory boards and Islamic finance experts. Findings The main finding of this study is that the development of Islamic green finance in Indonesia can occur through various channels, including greening Islamic capital markets, greening Islamic social finance, Islamic green finance and developing green banking services for the unbanked to support financial inclusion. Green sukuk, or Islamic bonds, are key financial instruments in Islamic green finance. They are used to fund projects in areas such as clean energy, mass transit, water conservation, forestry and low-carbon technology. These green financing initiatives also include socially responsible investments that are designed to improve the lives of people and communities. Research limitations/implications First, the availability of data on Islamic green finance practices in Indonesia may be limited, making it difficult to obtain a comprehensive understanding of the current landscape. Second, cultural and religious factors may play a role in the adoption and implementation of Islamic green finance, and these factors may vary across different regions in Indonesia. Practical implications The exploration and clustering of Islamic climate finance based on Islamic financial instruments in Indonesia can lead to the development of more sustainable and environmentally friendly practices in the financial industry. Originality/value This study serves as a pioneering effort to explore the potential and clustering of Islamic climate finance based on Islamic financial instruments in Indonesia.

Getting Ahead of the Game: Experiential Learning for Groundwater Governance in Ethiopia

Groundwater management is highly complex, with many users sharing the same resource often with limited understanding of their interconnectedness. Behavioral experiments (games) that simulate real-life common-pool resource use have shown promise as an experiential learning tool for improving resource governance. This study pilots an experiential learning intervention in Ethiopia using a groundwater game to help raise awareness of groundwater over-extraction and improve understanding of the importance of collective action in governance. In the Meki River catchment in Ethiopia, small-scale irrigation is expanding, but overextraction and competition over groundwater have not yet reached alarming levels. The groundwater game, adapted from India and including the addition of a rule-making round, was played in 15 villages with 30 groups. The game was accompanied by subsequent community-wide debriefing in each village to reflect on the experience and lessons learned, which stimulated discussions about groundwater governance. We surveyed participants to capture individual mental models regarding groundwater use and management, as well as any immediate learning effects. Focus group discussions in each village prior to the intervention and again six months after the intervention assessed possible lasting effects. The findings indicate cognitive, normative and relational learning, including increased understanding of groundwater dynamics (such as the joint effect of diverse water uses and users), the importance of collective action in resource management, and the benefits of communication. We find gendered differences in decision-making about resource extraction in the game and development of group-level resource management, confirming the need for gender-responsive approach to sustainable groundwater management interventions. We discuss community-wide learning and institution-building, and considerations for future intervention designs. We recommend embedding experiential learning, facilitated by local extension officers and other practitioners, in intervention packages that include both technical assistance on water-conserving technologies and groundwater management approaches and support in building communities’ institutional capacity.

Therefore, after understanding the research status of smart grid construction, this paper mainly studies the design and application measures of 3D simulation system for water and soil conservation of power grid according to the application advantages of VRGIS technology in smart grid management, so as to provide an effective basis for the development of smart grid.

Revitalizing Key Conditions and Integrated Watershed Management to Mitigate Land Degradation and Sustain Water Availability for Agriculture in Semi-Arid Regions: A Case Study of Ethiopia

Land, the source of 97% of global food, remains threatened by progressive soil erosion-induced land degradation, such as, in the semi-arid regions. To address this problem, soil and water conservation interventions have been implemented in watersheds across Ethiopia. Despite witnessing successful and positive impacts in some watersheds, the broader promotion of watershed-based interventions faces obstacles. Soil and water deteriorations persist in many of the watersheds in Ethiopia, leading to water shortages and related challenges in sustaining agriculture. The objectives of this research are thus to i) identify the main challenges and constraints hindering the promotion of watershed-based interventions in Ethiopia, and ii) identify key conditions for revitalizing the Integrated Watershed Management (IWSM) approach to mitigate soil erosion-induced land degradation, rehabilitate and sustainably manage watershed resources. A systematic review of over 60 published articles, extracted from the internet database using various search engines such as Google Scholar, ScienceDirect, Academia.edu, and ResearchGate, was conducted. Additionally, valuable comments from 65 peer-reviewers worldwide were collected through the Qeios platform during a posting period for more than two months, and these comments were utilized to update the first preprint version of this article. Based on the review, identified challenges and limitations include poor institutional support, lack of participation, inadequate planning of soil and water conservation (SWC) technologies, absence of research and development linkages, and insufficient capacity building. To address these challenges and limitations, recommendations for revitalizing the integrated watershed management (IWSM) approach and key conditions are discussed. The identified key conditions for revitalizing watershed-based interventions in Ethiopia include: i) ensuring institutional support and community participation, ii) strengthening the watershed-based intervention, and iii) establishing a watershed-based platform for scientific tools, research-based innovation, and capacity building to sustain water availability for agriculture in Ethiopia, serving as an experience for other semi-arid regions.

Evaluating the influences hedgerow on soil erosion and nitrogen loss of purple soil sloping farmland under simulated rainfall

Hedgerow is a vital soil and water conservation technology for sloping farmland that can significantly reduce erosion and nutrient loss via their above- and below-ground parts. The effect of hedgerow on erosion and nutrient loss has been widely investigated, while the respective effects of their above- and below-ground parts are still unclear. Therefore, the purple soil from the Three Gorges Reservoir Area was used, and 3 slope conditions of control check, whole hedgerow and hedgerow roots only combined with 2 slope gradients (15° and 25°) were constructed and the simulated rainfall tests were researched at 3 rainfall intensities (60, 90 and 120 mm h−1). The runoff initiation time, runoff and erosion rates, and loss of nitrogen via runoff and sediment were analysed. In comparison to the control check slope condition, it was indicated that hedgerow increased the runoff initiation time by 43.38 %, decreased runoff and erosion by 15.59 % and 78.37 %, and decreased nitrogen loss via runoff by approximately 40 % and via sediment by approximately 70 % on average, respectively. The average contribution rates of the below-ground part of the hedgerow was 49.89 % for the increase in runoff initiation time, 33.99 % for runoff reduction, and 39.91 % for erosion reduction. In addition, more than 2/3 and 58.49 % of nitrogen loss reduction via runoff and sediment, respectively, was contributed by the above-ground part of the hedgerow. These results are beneficial for comprehending the control mechanism of hedgerow on soil erosion and nitrogen loss, thereby provide a scientific foundation for the sustainable and efficient utilization of soil and water resources on sloping farmland.

Application of Biofilm Water Conservation and Emission Reduction Technology in the Pond Culture of Largemouth Bass and Japanese Eel

This study investigates the water-saving and emission-reduction effects of biofilm technology on the pond culture of largemouth bass (Micropterus pallidus) and Japanese eel (Anguilla japonica) using a combination of biofilm water purification grids and a complex microbial preparation. The results show that during the 150-day largemouth bass aquaculture trial, the TN, TAN, TP, nitrite, and LP in the treatment group were significantly lower than those in the control group by 26.2%, 74.7%, 53.9%, 30.7%, and 59.1% (p < 0.01), respectively. During the 145-day aquaculture trial of Japanese eel, the TN, TAN, and TP levels in the treatment group were significantly lower than those in the control group by 30.1%, 68.6%, and 18.7% (p < 0.01), respectively. The nitrite and COD levels were also significantly lower in the treatment group than in the control group by 18.3% and 16.0% (p < 0.05). In addition, largemouth bass and Japanese eel tailwater nitrogen and phosphorus discharges were significantly reduced and culture yields were significantly increased. This biofilm pond culture technology has advantages such as low cost, water saving and emission reduction, increased production, ease of operation, and a wide range of applications.

The impact of social interaction and information acquisition on the adoption of soil and water conservation technology by farmers: Evidence from the Loess Plateau, China

The adoption of soil and water conservation (SWC) technology is a key strategy for reducing global land degradation and improving agricultural productivity. This study uses survey data from households in the Loess Plateau in 2017 to evaluate the impact of social interaction on the decision-making process of SWC adoption by farmers. It measures the mediating effect of information acquisition and the moderating effect of internet use and deploys the probit model, general decomposition (KHB) model, and moderated effect model for analysis. The study found that the level of SWC adoption by farmers in the Loess Plateau of China remains relatively low, with only 57.3% of farmers adopting SWC, whereas social interaction increases the possibility of farmers adopting SWC by 10.0%. Accordingly, the paper argues that social interaction can encourage farmers to adopt SWC by improving their ability to acquire information, while internet use can positively moderate the impact of social interaction on farmers' adoption of SWC. Furthermore, the study found the positive impact of social interaction on SWC adoption is more pronounced for farmers in larger villages and those who join cooperative societies. Therefore, the research results provide a new perspective for promoting SWC in China, emphasizing the importance of enhancing social interaction improving farmers' ability to acquire information, and accelerating internet use.

Influence of planting basins on selected soil quality parameters and sorghum yield along an agro-ecological gradient in South Eastern Zimbabwe

Planting basins are an important soil and water conservation technology. This study evaluated the effects of basins on soil organic carbon (SOC) stocks, aggregate stability (Ima), bulk density, soil moisture retention and sorghum yield in agro-ecological regions III, IV and V of Chipinge district. The experiment consisted of three treatments; namely planting basins (basins) with goat manure and inorganic fertilizer application, hand hoeing with similar fertility amendments (FP+) and hand hoeing without fertility amendments (FP). It was hypothesized that planting basins with fertility amendments would improve the selected soil quality parameters and sorghum yield. Only planting basins significantly (p˂0.05) improved soil quality parameters in the 0-15 cm depth and bulk density, Ima, SOC stocks ranged from 1356 to 1451 kg/m3; 314 to 450 and 14.18 to 25.55 Mg ha-1 respectively. Planting basins significantly increased (p<0.05) sorghum yield relative to hand-hoeing practices (FP+ and FP) with average grain yield of 2.68, 1.72 and 1.32 t ha-1 in agro-ecological regions III, IV and V, respectively. When compared to FP+ and FP, basins increased grain yield by >130% in all the 3 agro-ecological regions. The hypothesis was accepted and it was concluded that basins improve soil properties and sorghum grain yield in agro-ecological regions III, IV and V. Considering the soil and crop productivity benefits highlighted in this study, there is a strong justification for the widespread promotion and adoption of planting basins in semi-arid agro-ecological regions of Zimbabwe.

The income and food security impacts of soil and water conservation technologies in Tanzania

Soil and water conservation technologies are critical in reducing drought and soil erosion risks and increasing crop yields and incomes. Yet, there is limited empirical evidence on the extent and impacts of adopting soil and water conservation technologies in Tanzania. The study’s objective is to evaluate the adoption (as well as the duration of adoption) and the impacts of soil and water conservation technologies on income and food security in Tanzania. The study employs a control function approach and the instrumental variable quantile treatment effects model to survey data from 575 households to estimate the average and distributional impacts of adoption. The results show that the adoption and duration of adopting soil and water conservation technologies had significant and positive effects on the total value of crop production and household income. Moreover, we find that the adoption and its duration had a significant and positive impact on the food security indicator—household dietary diversity. The results from the instrumental variable quantile treatment effects model also show that the impacts of adopting soil and water conservation technologies on the outcome variables are positive and significant, although they vary significantly across the income and food security distributions. The results indicate that even though adoption benefits households in both the lower and upper quantiles of the income and food security distributions, the marginal impacts of adoption are generally more significant for the households in the upper quantiles. The paper concludes by discussing the policy options for increasing and sustaining the adoption and impacts of soil and water conservation technologies in Tanzania.

Study on ecological environment impact and soil and water conservation technology of power transmission and transformation projects in typical ecologically fragile areas in western China

In the steady development of social and economic, the field of power transmission and transformation engineering construction in our country gradually forms a new electric power development pattern, providing a solid foundation for the innovative development of electric power enterprises in a new era. Since power transmission and transformation projects will cause serious soil and water loss, which will have a direct impact on the stability of ecological environment in various regions, which is not conducive to the construction and operation of power transmission and transformation projects and the long-term development of social economy, how to construct a safe and standardized construction environment, scientifically deal with the ecological environment problems of power transmission and transformation projects, and rationally use soil and water conservation technology? It is the main problem that Chinese scholars study and discuss at present. On the basis of understanding the environmental status of typical ecologically fragile areas in western China, and according to the development of soil and water conservation technology in power transmission and transformation projects, this paper mainly studies the online monitoring system and application technology of soil and water conservation for power transmission and transformation projects in a certain area, so as to provide effective basis for the construction management of power transmission and transformation projects in the new era.

Opinions on Irrigation Water Management Tools and Alternative Irrigation Sources by Farmers from the Delta Region of Mississippi

AbstractWater withdrawals for irrigation at an unsustainable rate resulted in a decline in the groundwater levels in the Mississippi River Valley Alluvial Aquifer (MRVAA) in the central southern USA. This drawdown of groundwater threatens agricultural production in the Mississippi Delta, an important agricultural region in the state of Mississippi, USA. Effective and efficient use of available resources is important to sustain and enhance agricultural productivity in this area. This study assessed the opinions of farmers on water conservation management practices and technologies that improve irrigation management and save water in the Mississippi Delta region based on data collected in an irrigation survey conducted in 2012. Most landowners believed that water conservation practices were effective in reducing irrigation water use without reducing maximum crop yields and have a positive return on investment. Land forming, tailwater recovery system, on‐farm storage, instream weirs to pond surface water, computerized hole selection for furrow irrigation, short irrigation runs, and irrigation scheduling were considered efficient water conservation technologies by landowners. Perceptions about use of different practices also depend upon the crops produced by the respondents. About 20 to 24% and 14.9 to 86% of survey respondents thought that on‐farm storage and center pivot, respectively, were inefficient water conservation practices for irrigating crops in the Mississippi Delta. The adoption of these practices may be increased if the landowners know the economic returns of implementing them.

Irrigation technology adaptation for a sustainable agriculture: A panel endogenous switching analysis on the Italian farmland productivity

Efficient water management in agricultural activities can improve local water resource conditions while enhancing farms’ economic performance. This paper analyses how farmers’ decisions to adopt innovative and sustainable irrigation systems, such as Water Conservation and Saving Technologies (WCSTs), would shape Italian farms’ economic resilience by improving land productivity. Using a Panel Endogenous Switching Regression Model, our results confirm that the WCST adoption is an endogenous and self-selective process and land value is endogenously determined. Seasonal aridity indices are important factors in the choice of WCST adoption, with different effects on non-adopters and adopters. Farmers who adopt WCSTs are more productive than those who do not.

The Effect of Empowerment on the Adoption of Soil and Water Conservation Technology in the Loess Plateau of China

Since there is a serious problem of land degradation and soil erosion in the Loess Plateau region of China, soil and water conservation technology (SWC) is necessary to protect land resources and reduce water loss, so as to promote the development of sustainable agriculture. By using the binary probit model, this study analyzes the effect of organizational, economic and self-empowerment on the adoption of soil and water conservation technology in the Loess Plateau region of China. The results indicated that all these empowerments have significant positive effects on the adoption of SWC, and there are significant gender differences in the impact. Organizational empowerment had a more significant impact on the adoption of SWC by male household heads, while economic empowerment and self-empowerment had a more significant effect on the adoption of SWC by female household heads. Therefore, more organizational and financial support for farmers is needed, and farmers themselves should have more confidence in the adoption of new technologies. Furthermore, given the gender differences in the impact, more gender equality should be ensured in the promotion of agricultural technologies.
