The Role of Agricultural Projects in Building Sustainable and Resilient Maize Value Chain in Burkina Faso

Poor seed quality and climate change significantly affect the maize value chain in Burkina Faso. To address the challenges, a catalytic project titled “Strengthening resilient seed systems in the maize value chain in Burkina Faso—from research to markets” was initiated to enhance the development of a resilient maize value chain. This study aims to assess the role of the project in developing a sustainable and resilient maize value chain. In this study, we used a mixed approach in design and implementation: qualitative research using key informants’ interviews, secondary data such as baseline survey reports, and lessons learned during the seed value chain greening intervention implemented in the Hauts-Bassins and Cascades regions of Burkina Faso. We analyzed qualitative data following the Gioia method. Kabako, a drought-tolerant hybrid seed variety, doubled crop yields in demonstration plots compared to smallholder farms and regional and national averages. Extension officers and village-based advisors (VBAs) were trained on improved seeds, composting, strip cropping, intercropping, crop rotation, and water management technologies and afterward trained smallholders. The VBAs trained smallholders on proper postharvest management practices and processing. The off-takers acted as the market. However, smallholders also sold their maize products in the informal open markets. The aggregator system was the missing link in Burkina Faso’s maize value chain. There was limited involvement of women in the project. Results obtained from this study are valuable for policymakers and value chain actors in preparing policies and filling missing gaps for exploiting the potential of the maize value chain.

Quantitative evaluation framework and application for regional water sustainability under local energy transition

Quantitatively analysing the impacts on regional water sustainability under the energy transition is vital to regional water management and specific technology selection, which is also relevant to dealing with climate change. This study proposed a new multi-indicator evaluation framework for regional water sustainability under local energy transition to quantitatively evaluate the water withdrawal and water environment during the energy transition from a lifecycle perspective. An integrated regional energy‒water evaluation model was also developed based on the Low Emissions Analysis Platform with a combination of lifecycle assessment and water footprint analysis. Shaanxi province in China was then taken as a case study, and the impacts of its energy transition on regional water environmental sustainability, including quantity and quality, were investigated under five scenarios. Results showed that the large-scale application of carbon capture, utilisation and storage technology and bio-energy equipped with carbon capture and storage technology could have additional advantages regarding CO2 emissions. However, such technologies exhibit a minimal effect on improving water environmental quality and reducing water demand for the first time due to the leakage of absorbents, CO2 and other risky substances during capture, transportation and storage from a lifecycle perspective. This finding drives the innovation of related breakthrough technologies with the promotion of water and end-treatment technologies in the future.

Blockchain for environmental peacebuilding: application in water management

PurposeThe purpose of this paper is to spur further exploration of blockchain technologies for environmental peacebuilding, specifically through water management. Although the environmental peacebuilding field acknowledges the potentially transformative nature of frontier technologies, most existing studies do not address how such technologies can contribute to peacebuilding through improved natural resource governance. Using a theory synthesis research design, this conceptual paper connects these studies to discuss how blockchain technologies in water management may contribute to environmental peacebuilding through the efficient and transparent management of natural resources.Design/methodology/approachThe authors use a conceptual approach and a theory synthesis research design to present potential mechanisms through which blockchain technology can potentially contribute to environmental peacebuilding.FindingsThe authors discuss the limitations in the literature on environmental peacebuilding, blockchain and water management, concluding that the third generation of studies should focus on the role of frontier technologies. This approach should especially address the negative consequences of technology for peacebuilding objectives. The authors argue that blockchain applications in water management can potentially contribute to environmental peacebuilding objectives in three ways: (i) creating a mechanism for confidence-building in low-trust contexts through automated and transparent water transactions, (ii) facilitating postconflict economic development through attracting capital and increasing the efficiency of water management and (iii) improving governance through greater transparency and local participation in natural resource management.Originality/valueTo the best of the authors’ knowledge, this study is among the first to conceptually explore the use of blockchain technology for water management in the context of environmental peacebuilding. The insights from this study can guide policymakers of conflict sides that focus on resolving issues such as lack of governance and low state agency.

Homogenous Climatic Regions for Targeting Green Water Management Technologies in the Abbay Basin, Ethiopia

Spatiotemporal climate variability is a leading environmental constraint to the rain-fed agricultural productivity and food security of communities in the Abbay basin and elsewhere in Ethiopia. The previous one-size-fits-all approach to soil and water management technology targeting did not effectively address climate-induced risks to rain-fed agriculture. This study, therefore, delineates homogenous climatic regions and identifies climate-induced risks to rain-fed agriculture that are important to guide decisions and the selection of site-specific technologies for green water management in the Abbay basin. The k-means spatial clustering method was employed to identify homogenous climatic regions in the study area, while the Elbow method was used to determine an optimal number of climate clusters. The k-means clustering used the Enhancing National Climate Services (ENACTS) daily rainfall, minimum and maximum temperatures, and other derived climate variables that include daily rainfall amount, length of growing period (LGP), rainfall onset and cessation dates, rainfall intensity, temperature, potential evapotranspiration (PET), soil moisture, and AsterDEM to define climate regions. Accordingly, 12 climate clusters or regions were identified and mapped for the basin. Clustering a given geographic region into homogenous climate classes is useful to accurately identify and target locally relevant green water management technologies to effectively address local-scale climate-induced risks. This study also provided a methodological framework that can be used in the other river basins of Ethiopia and, indeed, elsewhere.

Managing Toxins and Making Water ‘Safe’: Consumer Buffering Practices in Contexts of Chemo-Uncertainty

When it comes to water quality, seeing is not believing; even clear-looking water can harbour nefarious elements that are harmful to health. To protect against water’s hidden toxins, Indian consumers are adopting technologies designed to filter and mechanically ‘heal’ the waters they consume. This paper ethnographically examines the use(s) of household water management technologies based on ten weeks of ethnographic fieldwork in the city of Kochi, Kerala. It contemplates the socio-economic and anthropological significance of measures to filter and alkalinise tap water and to transform ‘dead’ municipal waters into healing waters with the power to ‘cure cancer’. Technological and infrastructural innovation is a means to an end in these safeguarding efforts; it enables what I argue are ‘buffering practices’ that allow a potentially dangerous element to feel restorative and wholesome once more. These insights add to scholarship exploring the rise of middle-class solutions for water safety in contemporary urban India.

Sustainability status of water management in oil palm plantations in peatlands: a case study in Koto Gasib District, Siak Regency, Riau Province

The purpose of this study was to evaluate the sustainability status of water management of oil palm plantations on peatlands and provide recommendations for water management. This research was conducted in Teluk Rimba Village, Koto Gasib District, Siak Regency, Riau Province. The sustainability analysis used was Multidimensional Scaling (MDS). The sustainability status category in this study is based on four basic scales (0-100); 24.9 (poor); 25-49.9 (less); 50-74.9 (enough); and > 75 (good), then a leverage analysis is performed to assess sensitive attributes. The results showed that water management in Koto Gasib District is in a very sustainable status with a value of 84.17. In the environmental dimension, land fertility is the most important aspect of oil palm productivity. In the economic dimension, farming capital and access to marketing are sensitive attributes. The social dimension has the most sensitive attributes. The technology dimension has two sensitive attributes, namely information and the introduction of water management technology as well as oil palm cultivation. The recommendations given are implementing a partnership in water management between private oil palm plantations and smallholder plantations.

INTEGRATION OF TRADITIONAL CULTURE AND MODERN TECHNOLOGY: AN EXPLORATION OF THE OPTIMIZATION OF CULTURAL ELEMENTS AND WATER SELF-PURIFICATION SYSTEMS IN THE TRADITIONAL CHINESE WATERSCAPE DESIGN

Traditional Chinese waterscape design is a profound cultural symbol and a perfect embodiment of the natural landscape. The philosophical ideas, aesthetic concepts and cultural connotations embedded in traditional Chinese culture have played an important role in the design of traditional water features. However, traditional water features have struggled to maintain their lasting beauty due to their impact on the environment and ecology. With the development of modern technology and advances in water management theory and techniques, modern water treatment systems have become an important means of solving water management and ecological and environmental problems. Combining traditional cultural elements with modern water self-purification systems has become an effective way to optimise traditional water features.
 This paper focuses on the cultural elements and water self-purification systems embedded in the design of traditional Chinese water features, and ways to optimise them with the help of modern technology. Firstly, the cultural background of traditional Chinese garden water features is analysed in terms of their unique traditional cultural elements, design methods and characteristics. Then, through the analysis and study of modern water management theories and technologies, the principles of realisation and optimisation strategies of water treatment are discussed. Finally, the combination of traditional cultural elements and modern water purification is used to explore in depth how traditional Chinese waterscape design can integrate traditional and modern elements, making it convenient for people while having a positive impact on the natural environment and ecology. The findings of this paper help to promote the combination of traditional culture and modern technology, and provide references and lessons for the environmental development of traditional Chinese waterscape design.

Farmers’ perceptions, adoption and impacts of integrated water management technology under changing climate

ABSTRACT This study investigates the correlations between Chinese banana farmers’ perceptions of integrated water management technology (IWMT) and their adoption behaviours and examines the impact of IWMT adoption on farm performance. The results revealed that farmers’ IWMT adoption correlates significantly with their perceptions of whether IWMT adoption can help reduce farm workload, fertilizer and water, the extent to which the technology is easier to operate, and the extent to which the technology can generate higher economic benefits than furrow irrigation technology. IWMT adoption significantly increases banana yields, gross revenue, net returns and irrigation frequency, but does not significantly affect irrigation expenditure.

Response of Fine-Root Traits of Populus tomentosa to Drought in Shallow and Deep Soil

Understanding the response characteristics of fine roots to soil drought of different degrees is essential for revealing the ecological adaptability of trees to different water environments and diverse plant resource absorption strategies. This study focused on a Chinese white poplar (Populus tomentosa) plantation stand, which gradually experienced the process of deep soil drying. In 2019 and 2021, by measuring the fine-root length density (FRLD), mean root diameter (MRD), specific root length (SRL), and root tissue density (RTD) of 1920 root samples and continuously monitoring the soil water content (SWC) in 0–600 cm soil layers, we explored the response characteristics of fine-root distributions and morphological traits relative to soil drought of different degrees. The results showed that P. tomentosa primarily changed the fine-root vertical distribution rather than the total amount of fine roots for coping with soil drought of different degrees. Shallow soil drought induced more fine-root distributions in the deep soil layer, while drought in both shallow and deep soil further aggravated this trend. Shallow soil drought restrained shallow fine-root growth, yet deep soil drought promoted deep fine-root growth. The very deep fine roots (400–600 cm) were more sensitive to soil drought than shallow fine roots. The shallow soil drought significantly increased the SRL of very deep fine roots; in contrast, when deep soil drought also occurred, the MRD and SRL significantly increased and decreased, respectively. In addition, fine-root morphological traits exhibited significant vertical spatial and temporal variation. MRD increased and then decreased, and the RTD gradually decreased with depth, while SRL had an increased trend in the very deep soil layer (400–600 cm). When the rainy season came, MRD and SRL increased and decreased, respectively. In conclusion, when facing gradual deep soil drying, P. tomentosa will use a large range of rooting patterns to meet the water demand of the canopy. These patterns range from “drought tolerant strategies” by distributing more fine roots in the deeper soil layer where water is abundant to “drought tolerant strategies” by changing very deep fine-root morphological traits to improve water-absorbing and transporting efficiencies. Our findings provide insight into the ecological adaption strategy of tree root systems relative to soil drought of different degrees in arid and semi-arid regions and provide crucial theoretical support for developing water management technologies to cope with deep soil drying under climate change.

Artificial intelligence for decentralized water systems: A smart planning agent based on reinforcement learning for off-grid camp water infrastructures

Abstract The planning and management of decentralized technologies in water systems is one of the promising, yet overlooked, domains where artificial intelligence (AI) can be successfully applied. In this study, we develop and deploy a reinforcement learning (RL)-based ‘smart planning agent’ capable of designing alternative decentralized water systems under demanding operational contexts. The agent's aim is to identify optimal water infrastructure configurations (i.e., proposed decisions on water management options and interventions) for different conditions with regard to climate, occupancy and water technology availability in a demanding, off-grid setting, i.e., a water system with high requirements of independence from centralized infrastructure. The agent is coupled with a source-to-tap water cycle simulation model capable of assessing and stress-testing the proposed configurations under different conditions. The approach is demonstrated in the case of a military camp deployed abroad for peacekeeping operations. The agent is tasked with selecting optimal interventions from an array of real-world camp water management technologies and evaluating their efficiency under highly variable, operational conditions explored through simulation. The results show that RL can be a useful addition to the arsenal of decision support systems (DSS) for distributed water system planning and management, especially under challenging, highly variable conditions.

Photocatalytic treatment of organoselenium in synthetic mine-impacted effluents.

Biological selenium reduction processes are commonly employed as the best available technology (BAT) for selenium removal; however, as a by-product they produce trace amounts of organoselenium compounds with orders of magnitude greater bioaccumulation potential and toxicity. Here, we assessed buoyant photocatalysts (BPCs) as a potential passive advanced oxidation process (P-AOP) for organoselenium treatment. Using a synthetic mine-impacted water solution, spiked with selenomethionine (96 μg/L) as a representative organoselenium compound, photocatalysis with BPCs fully eliminated selenomethionine to <0.01 μg/L with conversion to selenite and selenate. A theoretical reaction pathway was inferred, and a kinetics model developed to describe the treatment trends and intermediates. Given the known toxic responses of Lepomis macrochirus and Daphnia magna to organoselenium, it was estimated that photocatalysis could effectively eliminate organoselenium acute toxicity within a UV dose of 8 kJ/L (1-2 days solar equivalent exposure), by transformation of selenomethionine to less hazardous oxidized Se species. Solar photocatalysis may therefore be a promising passive treatment technology for selenium-impacted mine water management.

Investigation of Irrigation Water Requirement and Evapotranspiration for Water Resource Management in Southern Punjab, Pakistan

Water scarcity and water quality degradation are exacerbated by climate change in all countries, including Pakistan. The use of water in agriculture is one of the most predominant resources, so reducing consumption and improving resource management is of utmost importance. In the past few decades, excessive irrigation has led to severe water scarcity and reduced water quality. This study determined the irrigation requirements for cotton, rice, and wheat, using the CROPWAT model in Southern Punjab (Multan District). In the study area, evapotranspiration ranged from 1.8 to 10.24 mm/day, while effective rainfall ranged from 2 to 31.3 mm. Rice, cotton, and wheat each required 996.4, 623.3, and 209.5 mm of irrigation, respectively. Among rice, cotton, and wheat, the total net irrigation was 72.4, 67.8, and 44.1 mm, respectively, while the total gross irrigation was 103.5, 99.8, and 63 mm. The CROPWAT model showed a moderately useful result for identifying irrigation needs in Southern Punjab. The study emphasizes the need for groundwater harvesting and water management technologies to implement a water management system that reduces water shortages.

Economic analysis of public investment in alternative agricultural water management schemes: a case study from northern Ghana

ABSTRACT This study assesses the institutions and economics of public investments in three agricultural water management infrastructure and technologies: rehabilitation of small reservoirs, fuel-powered motorized small pumps and electricity-powered large pumps. We find that all three technologies yield positive returns on investment, but their applicability varies spatially and across community due to differences in capital costs and environmental feasibilities or conditions. Sensitivity analyses indicate the base decision parameters – net present value, benefit–cost ratio and internal rate of return – remain stable despite potential changes in the flow of future benefits or costs. This provides further evidence about the worthiness of investment in irrigation infrastructure and technologies. However, significant under-utilized infrastructural capacities exist that warrant complementary investment in human and institutional capacities. Based on the findings policy recommendations are provided.

Sustainable Strategy for Rice Crop Management in Pinrang Regency, South Sulawesi, Indonesia

Climate change is one of the trending topics to be discussed at both the practical and political levels. Climate change has a significant effect on rice plants because rice cultivation is dependent on climate elements, especially rainfall, and temperature, the phenomenon of climate change has triggered an increase in the intensity of extreme events such as floods and droughts, causing crop failure, crop failure and even cause puso. Pinrang Regency is one of the regions in Indonesia that feels the impact of climate change on the agricultural sector. The research aims to develop appropriate adaptation strategies to climate change for rice crop management. The technique of collecting data is through in-depth interviews with respondents, namely rice farmers in Pinrang Regency using a purposive sampling technique. Data analysis uses SWOT analysis (strengths, weaknesses, opportunities, and threats), by determining internal factors and external factors and formulating climate change adaptation strategies for rice crop management in Pinrang Regency using an analytical tool, namely the SWOT matrix. The results showed that the strategies that could be implemented for the management of rice plants in Pinrang Regency were cultivating farmers by applying irrigation technology, developing water management technology, optimizing the performance of farmer groups, providing intensive climate information, and cultivating environmentally friendly technologies.

Improving water management technology in rice systems for sustainable rice production

Purpose: to reduce rice irrigation rates by developing water management in rice systems for sustainable rice production. Materials and methods. The materials for the study were data obtained for 2020–2022 in production experiments in three experimental farms in Krasnodar Territory, the total area of which was 59,636 hectares. The idea of decreasing the irrigation rate by reducing the duration of flooding period, the number of discharges, the rate of one-time irrigation, the repeated flooding, the intensity of vertical filtration and physical evaporation is discussed. Water consumption, transpiration and seepage effluent were determined when defining the irrigation rate for the shortened flooding and the combined irrigation using the method of vegetation vessels with an area of 3000 cm². For an environmentally friendly technology, evaporation and transpiration were additionally determined using a GGI-500-50 evaporator at the stage of two or three leaves in rice crop during sprinkling irrigation. Results. The analysis (water-physical properties of soil, chemical analysis of soil samples, content of ferrous and ferric iron in soil) of existing (basic) rice cultivation technologies: shortened flooding and combined irrigation, was carried out. Integral curves of evaporation and evapotranspiration were constructed on the basis of observational data on vegetal discharge. Conclusions. A new environmentally friendly technology for rice cultivation was developed. As a result of evaluation the declared technology, its efficiency expressed in a reduction in irrigation rate by 10 % due to a decrease in evaporation, daily transpiration and vertical filtration was proven.

Effect of climate smart agriculture technologies on crop yields: Evidence from potato production in Kenya

Climate change is one of the current global issues of concern given that it is affecting agricultural production. Sub-Saharan Africa (SSA), which frequently experiences severe weather and natural disasters, is particularly vulnerable to climate change. Even though numerous measures are being promoted to mitigate climate change in SSA, little evidence exists regarding the adoption of climate-smart agriculture (CSA) technologies in potato farming and its effect on yield. CSA is widely acknowledged as a crucial technique for farmers to adapt to climate change and raise agricultural productivity. This study investigated the effects of CSA technology adoption among potato farmers in Kenya. A descriptive survey was adopted. A multistage sampling technique was used to randomly select 350 potato farming households in Nyandarua County. Data was collected using a questionnaire and interview techniques. Propensity Score Matching (PSM) was used to evaluate the effects of CSA technologies on potato yields. The results indicated that on average potato farmers adopted 8 out of the 18 CSA technologies. The PSM results indicated that the adoption of CSA technologies improved potato yields. Adoption of seed management technologies enhanced potato yield by 61 % followed by soil nutrient management, crop improvement practices, seed management, and crop protection techniques by 50 %, 41 %, 40 %, and 39 %, respectively. This implies that smallholder farmers' adoption of climate-smart technologies is critical for increasing and maintaining potato yield. However, adopting water management technologies like water harvesting and irrigation negatively affected potato yield. The study discusses the implications of these findings.

기후변화 대응을 위한 디지털 물 관리 기술의 적용

As abnormal climates occur frequently around the world, the frequency and intensity of natural disasters are increased. In this study, trends of natural disasters are analyzed and identified the applied technology of smart water grid and digital water management, which are the latest water management systems to respond to climate change. Water-related damages such as typhoons and floods accounted for a large proportion of natural disasters around the world. In the case of Asia, it was found that over the past 50 years, typhoons caused the largest casualties of human life, and the biggest economic loss was caused by floods. In the case of Korea, the biggest economic loss over the past 10 years was disasters caused by floods and typhoons. In order to minimize the damage caused by these disasters, digital water resource technology is being applied worldwide. In this study, application cases of smart water management and digital technologies were investigated. In addition, the application direction of digital water management technology was proposed.

Yield, water productivity and nutrient balances under different water management technologies of irrigated wheat in Ethiopia

Development of irrigation technologies and agricultural water management systems holds significant potential to improve productivity and reduce vulnerability to climate change. Our study dealt with the behavior of irrigation water productivity, partial nutrient balance and grain yield of wheat under the application of different irrigation water management technologies in the Koga irrigation scheme in Ethiopia. For our analysis, we considered three nutrient fluxes entering and leaving farmers’ fields. Our experimental design had three irrigation blocks with three different irrigation water management practices (wetting front detector, Chameleon soil moisture sensor and farmers’ practice as control) on three farm plots replicated in each block. To calculate irrigation water productivity and grain yield of wheat, the amount of irrigation water applied and the agronomic attributes of wheat yield were recorded during the irrigation period. Further, three input and output variables were considered to determine the partial nutrient balances of nitrogen (N), phosphorus (P) and potassium (K). The results showed that the amount of irrigation water used was 33% and 22% less with a wetting front detector and Chameleon sensors, respectively, compared to the farmers’ practice. The wetting front detector (WFD) and Chameleon sensor (CHS) treatments gave a 20% and 15.8% grain yield increment, respectively, compared to the farmers’ practice plot. The partial nutrient balances of N and K were negative for the wetting front detector and chameleon sensor practices while it was positive for P in the control (farmers’ practice) treatment. We conclude that irrigation water management with appropriate technologies can improve yield, water productivity and the nutrient utilization. However, further research needs to be conducted on the suitability of irrigation management technologies to achieve full nutrient balance.
