INFLUENCE OF FARMER MARKETING STRATEGIES AND WATER USERS ASSOCIATIONS ON PERFORMANCE OF SMALLHOLDER IRRIGATION PROJECTS IN MIGORI COUNTY, KENYA

Objective: The objective of this study was to investigate influence of farmer marketing strategies and water users associations on performance of smallholder irrigation projects, and was aimed at enhancing smallholder irrigation project outcome success in Migori County, Kenya. Theoretical Framework: The study was anchored on market orientation theory by Kohli and Jaworski (1990) and Narver and Slater (1990). This is because market orientation explains relationship between markets and organisational behaviour (Gotteland et al., 2007). Kohli and Jaworski (1990) explain customer needs, market competition and usefulness of a product as interacting to influence its marketability. Method: Using cross-sectional and correlational research design, the study collected data from 341 farmers out of a target population of 2815 in 15 smallholder irrigation projects in Migori County using a 5-Point Likert Scale questionnaire. The data was analysed using descriptive and inferential statistics. Results and Discussion: The results show that farmer marketing strategies accounts for 64.1% of findings in the model, with group marketing having the most significant influence on performance. The results also show that introduction of water users associations increases coefficient of determination (Δr2) by + 0.121, indicating a positive modest moderating influence on the relationship between predictor and dependent variables. Research Implications: The study confirms that farmer marketing strategies influence performance of smallholder irrigation projects, and that water users associations positively but modestly influence the relationship. Empirically, the study highlights the importance of cooperative societies, agro-processing and irrigation management transfer in smallholder irrigation. Originality/Value: This study adds to empirical data on farmer marketing strategies, water users associations and smallholder irrigation. In highlighting these aspects, the findings have potential to benefit development agencies in smallholder irrigation.

Holding Stakes in Water Management and Irrigation in Morocco : PIM policy Effects

The main policy reforms concerning irrigation management in Morocco over the last thirty years have been the introduction of mechanisms aimed at achieving financial autonomy of the Administration in charge of irrigation systems managemement -Offices Régionaux de Mise en Valeur Agricoles (ORMVA)- by applying appropriate water pricing and involvement of water users in the operation and maintenance of their irrigation systems, by transferring some responsibilities to water users' associations (AUEA). These policy reforms were presented by the World Bank projects (PAGI1 and PAGI 2) as crucial steps that Morocco should take to improve the productivity and sustainability of its irrigation sector. After more than thirty years, implementation of these reforms has been fraught with difficulties and many delays. Results and impacts are very timid and vague. The Moroccan GPI experience shows that an “ingredient” was missing to drive change. In fact, setting up new local organizations to participate in irrigation management and calls for new institutional arrangements to tackle the huge problems of moroccan large scale irrigation sector is not sufficient to drive change. A profound realistic thinking on irrigation governance and large concertation between water users are needed to meet the challenges of water scarcity, climate change and water security in the country. This article assesses the participation of Water Users' Associations (AUEA) established in Tadla irrigated scheme in Morocco. It reviews the contxt of adoption of the Participatory Irrigation Management (PIM) policy in Morocco and re-examines the process of initiating and developing AUEAs in large irrigated perimeters, analyzing the specific case of the Beni Amir irrigation project. The questions of participatory planning and joint management are at the heart of our analysis.

Sudan's catastrophe: the role of changing dynamics of food and power in the Gezira agricultural scheme.

This article explores the role of historical, political, and economic processes in understanding war and famine in Sudan after 2023. The focus is on Al-Gezira, the site of Sudan's largest agricultural scheme. Using ethnography, interviews, and document reviews, the study analyses the Gezira irrigation project in three phases. First, the 1980s and 1990s, when patronage politics dominated its management. Second, the neoliberal strategies of the Gezira Scheme Act of 2005, which enabled Islamist profiteering while increasing vulnerability among farmers and labourers and tensions between them. Third, post 2018, when political movements used evidence of the scheme's deterioration to call for revolution, but once achieved, previous tensions grew and have been manipulated during the war. Sudan provides an example of how decades of war and neoliberal economic strategies have led to a deeply-rooted, violent, and extractive political economy. This has been to the benefit of business and elites, leaving many to a life of precarity, exploitation, and hunger.

Assessing the influences of future water development projects in Tekeze-Atbara-Setit basin on the Nile River inflow at Aswan, Egypt

Study regionThe Tekeze-Atbara-Setit (TAS) basin as a portion of the Eastern Nile Basin (ENB) in Africa. Study focusENB consists of four sub-basins; one of them is the Tekeze-Atbara-Setit basin. TAS basin is subject to future water development projects, including irrigation projects and hydropower dams. Potential impacts of these projects need to be assessed regarding the inflow and hydroelectric generation at Egypt's High Aswan Dam (HAD). New hydrological insights for the regionTwo models are coupled offline; The Soil Water Assessment Tool (SWAT) model and HEC-Reservoir Simulation Model (HEC-ResSim). Base-case scenario is created without the expected future projects, in addition to five additional scenarios representing hydropower and irrigation projects. The maximum annual inflow at HAD declines by 1.6 km3 in the hydropower scenarios, while the produced power at HAD descends by 9.5 %. The maximum reduction in the annual inflow for hydropower and irrigation projects scenario at HAD is 4.63 km3 and 35.2 % for power reduction. Finally, the proposed future development project in TAS basin will have negative impacts on the flow, and generated hydropower at HAD in Egypt.

Estimation of Reservoir Storage Capacity Using the Gould-Dincer Formula with the Aid of Possibility Theory

This paper presents a method for estimating reservoir storage capacity using the Gould–Dincer normal formula (G-DN), enhanced by the possibility theory. The G-DN equation is valuable for regional studies of reservoir reliability, particularly under climate change scenarios, using regional statistics. However, because the G-DN formula deals with measured data, it introduces a degree of uncertainty and fuzziness that traditional probability theory struggles to address. Possibility theory, an extension of fuzzy set theory, offers a suitable framework for managing this uncertainty and fuzziness. In this study, the G-DN formula is adapted to incorporate fuzzy logic, and the possibilistic nature of reservoir capacity is translated into a probabilistic framework using α-cuts from the possibility theory. These α-cuts approximate probability confidence intervals with high confidence. Applying the proposed methodology, in the present crisp case with the storage capacity D = 0.75, the value of the capacity C was found to be 1271×106 m3, and that for D = 0.5 was 634.5×106 m3. On the other hand, in the fuzzy case using the possibility theory, the value of the capacity for D = 0.75 is the internal [315,5679]×106 m3 and for D = 0.5 the value is interval [158,2839]×106 m3, with a probability of ≥95% and a risk level of α = 5% for both cases. The proposed approach could be used as a robust tool in the toolkit of engineers working on irrigation, drainage, and water resource projects, supporting informed and effective engineering decisions.

Animal and Plant Wealth and its Impact on the Economy of Mesopotamia

1- The first period of human life in prehistoric times was known as the period of food gathering economy, as it depended on gathering wild plants and hunting animals, and made simple tools and machines from stones and animal bones that were used in hunting, and used tree leaves and animal skins to make clothes. As for the second period, the Neolithic era, it was known as the period of food production economy when he learned agriculture and domesticated animals. Agriculture was initially described as meeting the need and was cultivated in small areas and in one season. 2- When he learned the life of stability and lived in permanent villages, the oldest of which is the village of Jarmo, many tools were found made of flint, stone vessels, spoons and pottery. In addition, the village contained permanent houses and clay ovens for making bread, fireplaces, basins, stoves and clay dolls. 3- Domesticating animals, especially goats, sheep and pigs, benefiting from their meat, cheese, skins and fat to make oils, and domesticating dogs. 4- The most important crops that he cultivated were wheat and barley, and later in other areas he cultivated lentils, flax and legumes. 5- In the Stone Age, he learned fertilization and artificial irrigation. He cultivated large areas and had a surplus in production, which prompted him to make large-sized stores to store the surplus, noting that the stores had existed since the era of Hassouna, but they were small. He also learned trade and the barter system and the discovery of metals. Specialization in work and division of labor appeared, and other crafts and professions appeared. The pottery wheel, spinning and weaving discs, and seals were invented. 6- Wool and hair of sheep and goats and some plants such as flax were used to make clothes using spinning discs. 7- Many pottery vessels of different sizes and shapes were found, and they contained drawings, decorations, engravings, and colors of great precision, some of which were made by hand and others with a pottery wheel. Tools and machines were made of copper. 8- Moving to the south and the emergence of large cities, carrying out irrigation projects, and the emergence of the first systems of government. 9- A change and development occurred in the human mind, benefiting from the natural environment and the wealth it contains that could serve him as a result of the development of social , cultural and economic life. 10- Plant cultivation and domestication were coupled with animal husbandry and domestication, as both complement each other in terms of benefit. Because of them, other crafts and professions emerged, including the manufacture of tools and machines, pottery and weaving. Trade also flourished as a result of an increase in the surplus and the increase in labor. 11- Learning how to extract oils and methods of obtaining them from plants and animals which was of great importance because it had multiple uses, especially in cooking, and the demand for it increased in trade. 12- Plant and animal wealth played an important role in its prosperity and economic recovery, as it represented the backbone of the economy of Mesopotamia. 13- Our information about animals and plants came from cuneiform texts and seals that show scenes of hunting animals, scenes of grazing sheep, scenes of ears of wheat and plants, and from murals on the walls of palaces, scenes of barns designated for raising animals, scenes of relief and three-dimensional sculptures that show domesticated domesticated animals, and scenes of hunting predatory animals.

Improving Water Efficiency Through Channel Lining - A Case Study of the Birinchiguri Runoff Irrigation Project in Assam, India

Water is the most essential commodity for human beings to be alive and so it is very necessary to make proper use of water without wasting it. Irrigation sector is the biggest consumer of water as more than 80% of available water resources in India is being presently utilized for irrigation purposes. However, the average water use efficiency of irrigation projects in the country is assessed to be only of the order of 30 to 35%. In the north eastern region also, performance of the existing irrigation schemes suffer from low water use efficiency due to distribution losses and poor operational maintenance and management and results in non - availability of water in the tail ends. Again, water demand for various purposes namely irrigation, drinking, domestic, power, industrial and other uses is increasing day by day leading to severe seasonal stress on water resources in the region. Its scarcity is more pronounced with increasing population and needs. In the present study, the water use efficiency of the Birinchiguri Flow Irrigation Project is determined as per methodology given in the guidelines for computing the Water Use Efficiency of the Irrigation Projects, Central Water Commission (CWC), February, 2014. It has also been attempted to analyze the scope of improvement of water use efficiency of the same.

Application of knowledge graph in smart irrigation district management decision making

Regarding the traditional irrigation and drainage management methods in China's irrigation districts, there are problems such as complex management processes, dispersed information systems, difficulty in resource sharing, diverse data sources, and insufficient intelligent auxiliary decision-making. In order to further realize refined intelligent management decision-making on issues related to smart irrigation districts, this article uses the basic information of 28 Yellow River diversion irrigation districts in Henan Province, as well as the overall plan reports and related issue management manuals of 7 management offices of the first and second phase projects of Zhaokou Irrigation District as data sources. Collect and organize data from irrigation areas, and use these to build a knowledge graph for management of issues in irrigation areas diverted from the Yellow River. At the same time, the BERT + BiLSTM + CRF model is used to intelligently identify entities such as irrigation projects and problem events in the Zhaokou Irrigation District inspection log text, and entity alignment technology is used to match the inspection text with entities in the knowledge graph. Finally, combined with the graph retrieval function, the intelligent generation of smart irrigation district management decision-making solutions is realized. The validation of specific irrigation district examples and analysis of the evaluation indexes of relevant models demonstrate the reliability of the problem management decision-making scheme proposed in this paper. This application effectively facilitates the integration of information data in the Yellow River diversion irrigation area and enables visual management of intelligent irrigation zones, presenting a novel concept for the informationization construction of China's irrigation areas.

Research progress on operation control and optimal scheduling of irrigation canal systems

AbstractOpen canals are a common water transfer method used in water transfer projects and agricultural irrigation and drainage projects. With the emergence of drawbacks in traditional canal control models and the increasingly severe shortage of water resources, accurate transport and distribution of water in the canal system of the irrigation district, rational allocation of water resources, reduction in water loss, improvement in the efficiency and benefit of water resource utilization, and satisfaction of the water demand of different water users are needed. Many scholars have conducted extensive research on canal operation control and optimal scheduling. This paper systematically reviews and summarizes the relevant research progress, including the theory of unsteady flow in open canals, the operation mode of the canal system, the operation control model and algorithm of canal systems, and the optimization of water distribution in canal systems. By summarizing the research progress already achieved, the existing problems and future development directions are identified according to actual needs, providing a reference for the ongoing modernization of irrigation districts and the research and application of digital twin irrigation district technology.

Vector Borne Disease Ecology and Environment: Remote Sensing and GIS for Control and Management: A Systematic Review

The prevalence of vector borne disease epidemics are influenced by the thickness of the vectors persistent to climate, landscape, and environment. Historically evidenced of triggering epidemics in both vertical magnitude and horizontal spread (spatial diffusion) of increasing vector borne diseases, such as; malaria, dengue, chikungunya, Japanese encephalitis, filariasis, leishmaniases, scrub typhus, Kyasanur forest disease (KFD), West Nile virus, Lyme disease, Zika virus, and Rift valley fever in the tropical and subtropical regions, particularly, in the third world countries for the past several decades. The geographical analysis of each one VBD epidemics has a unique vector ecology and environment. The prevalence of epidemic distribution patterns and seasonal variations, and associated vector ecology were analyzed throughout the world for the past periods, in order to assess the probability of potential risk and delineate the hotspot regions susceptible to the VBD outbreaks in the country, using Remote Sensing and GIS mapping analysis. It offers a quick and efficient approach to mapping of land uses/land cover patterns and its changes over space and time, and the information on these changes linking with vector profusion and disease ecology. Vector-borne disease epidemics across the country have been evidently associated with climate factors, landscape changes, potential breeding sources; such as, water bodies, rivers, streams, and mega water resource irrigation projects, dams / reservoirs, water pools, lakes, urban agglomerations, Urban sprawl, urban dynamics, industrial developments and growths, floating population, urban migration, land use / land cover changes, wet irrigation agriculture practices, seasonal migrations on occupation, cargo shipping movements, trade and commerce, etc., and have been acted upon changing the aboriginal territories by extent of epidemic scenarios into the non-endemic regions. The integrated Earth Observation Resource Satellite data integrated with GIS has effectiveness upon proved to disease mapping, ecological niche modeling, risk assessment, spatial prediction, and offering answers to both the public health programmers and research scientists concerned on vector fecundity, and vector borne disease ecology, and thus, the geographical, ecological and environmental determinants of its range is considered to be essential for sustainable public health planning. Accordingly, prevention measures and appropriate control strategy may possibly be applied during the sporadic outbreaks situations in the new epidemic regions as well in the hot spot endemic regions regularly, so as to control the erratic transmission and prevent acceleration of epidemics early in advance successfully.

SCARCE RESOURCES, GREAT CHALLENGE: CENTRAL ASIA'S WATER CRISIS AND ENVIRONMENTAL SUSTAINABILITY

Central Asia has limited water resources and increasing pressure on these resources. Large-scale irrigation projects initiated during the Soviet Union led to the over-exploitation of the Amu Darya and Sir Darya rivers and the dramatic drying up of Lake Aral. This process has caused extensive damage to the ecosystem, declines in agricultural productivity and serious problems in human health. The article analyses the historical origins and the current state of the water crisis in the region and examines the challenges of water resources management and sustainability efforts. It will also emphasise the importance of regional cooperation and modern water management policies. Central Asia's water crisis is not only an environmental problem but also a social and economic challenge. In this context, sustainable water management strategies are vital for the region to achieve its long-term development goals. Türkiye’s cooperation with the Central Asian states in this regard and transferring experience to them will contribute to the regional states' confidence in Türkiye and increase Türkiye’s prestige in the international arena. The article will use the Russian, English, Turkish and Uzbek source search method.

Cost–benefit analysis on the implementation of nature-based treated wastewater reuse: case of sekem farm El-Wahat, Egypt

In a context of increasing pressure on water resources and severe aridity; expansion in the reuse of naturally treated wastewater can be a viable and low-cost solution particularly for irrigation forests, green non-fruit trees, fabric crops, industrial oils, and non-edible raw crops. Wastewater treatment is increasingly recognized as a potential means in El-Wahat El-Bahariya in Egypt. However, investment decisions concerning the reuse of treated wastewater in irrigation needs to be justified in terms of financial and economic feasibility and profitability. Therefore, this research study aims to conduct a cost–benefit analysis (CBA) of an investment project “reuse treated wastewater in irrigation compared to other modes of water irrigation projects. The CBA results revealed that the cost of the initial investment for the production of treated water used for irrigating green non-fruit trees, Bamboo trees, and Cactus in Sekem El-Wahat, is economically efficient with 88% compared to the exploitation of aquifer groundwater for irrigating the same crops. That project allows for an economic gain of about 4,428.5 €/ha compared to the cost of producing aquifer ground water in Sekem Farm El-Wahat is estimated at 10,800 €/year. Substituting the use of aquifer ground water for irrigating crops with reuse of treated wastewater helps reducing energy consumption and offers great financial benefits to the beneficial communities. A net benefit of the reuse of treated wastewater project is largely positive with NPV equivalent to 4599 €/year with a medium economic efficiency (BCR) of about 0.44.

Influence of Diffusion Angle on Sediment Concentration in Front Inflow Forebay of Pumping Station

Abstract The numerical simulation and field investigation of solid-liquid two-phase flow are carried out in a large-scale forward intake forebay with various diffusion angles at the Jingtaichuan Pumping Irrigation Project in Gansu Province, China. The purpose is to investigate the properties of sediment deposition in the pumping station forebay. The results indicate that the low-sediment concentration area is in the forebay’s centre, whereas the high-sediment is near the two side walls flanks. The sediment concentration increases dramatically from the centre to the sides. Both the high-sediment concentration area and the sediment concentration increase with water depth. The forebay’s narrowing diffusion angle causes the high-concentration area to gradually decrease while the low-concentration area gradually increase. Furthermore, the amount of siltation and sediment deposition efficiency decrease, resulting in a large increase in forebay sediment concentration and sedimentation efficiency. The sediment concentration and water flow velocity reveal a quadratic polynomial relationship. This study can provide a guide and reference for the design and construction of comparable large-scale pumping station forebays.

Gi’iko Ce:mo’oidag: A proposal for urban-agrarian development in the Gila River Indian Community, Arizona

The urban fabric of the Phoenix Metropolitan Area (PMA) is becoming inhospitable. Contributing factors are: low population density, dependence on automobiles and air conditioning, Urban Heat Island effect, uncertain water supply, lack of sustainable policies, and low community connectivity. Failing to adapt could spell the end of the PMA’s life cycle. This paper highlights the Indigenous Akimel O’Otham as key agents of sustainable change in this region, on account of their espousal of sustainable values; and their water rights reclamation allocating resources for agricultural development, of which the tribe has already undertaken the Pima-Maricopa Irrigation Project (P-MIP). The design presented offers a possible avenue for the tribe to complement P-MIP’s ambitions with urban-agrarian development, diversifying the uses of their water supply. The proposal is accompanied by a speculative financial plan to ensure their independence from external investment. This could contribute to fostering urban change and promoting a more resilient future.

Identifying suitable boreholes for irrigation in the bedrock regions of the Sahel

AbstractThis study addresses the critical challenge of optimizing borehole drilling techniques and predictive models to improve groundwater utilization for irrigation in Burkina Faso. Initially, the analysis involved drilling 22 boreholes as part of a photovoltaic micro‐sprinkler irrigation project (PRECIS), with only 11 deemed suitable for irrigation, highlighting the difficulty in achieving the required flow rate of 5 m3/h. To enhance the robustness of the study, additional data from 205 high‐yield boreholes provided by the Office National de l'Eau et de l'Assainissement (ONEA) were incorporated. These boreholes, primarily intended for potable water supply, had flow rates often exceeding 5 m3/h. This extensive dataset was crucial in identifying significant predictors of the project flow rate (Qproj), including the flow rate at the end of drilling (QEndBorh) and lithological factors. The predictive model combining QEndBorh and lithological data explained 73.7% of the variance in Qproj, with an adjusted coefficient of determination (R2adj) of 72.4%. The CART (classification and regression tree) regression model effectively identified branches with flow rates suitable for irrigation, such as Terminal Node 3 with a predicted Qproj of 6.67 m3/h and Terminal Node 4 with a predicted Qproj of 10.5 m3/h, demonstrating the model's robustness. These findings underscore the necessity of detailed lithological assessments and advanced predictive modelling to ensure efficient and reliable borehole drilling for irrigation purposes in regions with complex geological conditions.

Social and Economic Consequences of Farmer Suicides in Karnataka: Impacts on Rural Communities and Beyond

In this research paper, an attempt has been made to overview the present scenario of farmer suicides in Karnataka, India, is given in the abstract, along with a focus on the disastrous social and economic effects of this phenomenon. In fact, there were 3,515 farmers committed suicide between 2013 and 2018, with small and marginal farmers who owned less than 5 acres of land being the bulk of these deaths. The main causes of these suicides were debt, crop failure, and limited access to institutional funding. Farmers who commit suicide have far-reaching effects on society in addition to the agricultural community. Declining agricultural output, rural-to-urban population mobility, and the breakdown of social structures are all problems facing rural communities. Reduced agricultural output, a loss of revenue for farming households, and an increase in the demand on government resources for relief operations are of the economic effects. The social consequences include a rise in domestic violence, mental health issues, and alcoholism in rural areas. The summary highlights how farmer suicides have an impact on metropolitan people who rely on agricultural goods for their sustenance, in addition to remote rural communities. The Karnataka government has launched programs including loan waivers, crop insurance policies, and irrigation projects to prevent farmer suicides. To address the root reasons of farmer suicides, further work must be done. This work should focus on supporting sustainable farming practices, increasing institutional funding availability, and offering mental health services to farming communities.
