In Africa, Swaziland is atypical in being a small country. Nevertheless, it is agriculturally and climatically diverse and its problems are relevant to other sub Saharan countries. This article reviews large-scale irrigation schemes in the context of such factors as traditional land tenure, soil variation, crop management techniques, and availability of technical support. A later article will discuss problems of small-scale irrigation.

Water cycles exist in all processes of water resources utilization, including water-saving irrigation. Due to the complex water cycle process of irrigation, the ecological effects and safety of large-scale water-saving irrigation have received increasing attention. This paper analyzed both the positive and negative ecological effects of water-saving irrigation and the scale effects from the plant-scale to the watershed-scale. Based on the Vensim and GMS (Groundwater Modeling System) models, a quantitative evaluation method of ecological safety of large-scale water-saving irrigation was proposed. The case study in Changma Irrigation District in the arid inland river basin of Northwest China showed that the ecological safety of large-scale water-saving irrigation was sensitive to the combination of water source condition, water distribution technology and water-saving irrigation technology in field. In terms of the positive effects, large-scale water-saving irrigation can reduce the percolation loss of irrigation water, increase the environment water flow for the downstream, and slow down the salinity accumulation. As for the negative effects, large-scale water-saving irrigation could reduce the groundwater recharge, decrease the environment water supply in local farmland, and cut down the soil salinity leakage. The research results have positive significance for guiding the sustainable development of water-saving irrigation and conservation of ecosystem in an arid inland river basin.

The concept of ecosystem and ecosystem management services has given rise to different definitions and classifications. Ecosystem may be defined as a natural unit of living things and their physical environment. Ecosystem concept shows the relationship of biodiversity and ecosystems and the benefits are the services enjoyed by humans. In the past, ecosystem resources were used by multiple groups and individuals across sub-Sahara for variety of purposes, sustaining agrarian livelihood through the use of customary laws and traditional social structures. After the Ghana’s 1992 amended constitution, lands in large-scale irrigation in the northern Ghana were returned to the traditional custodians. The study seeks to establish the current role of traditional custodians’ management of ecosystem in irrigation landscapes. The study was conducted in the Tono and Bontanga irrigation landscapes in Northern Ghana using participatory impact assessment methods. Despite the return of lands in irrigated landscapes, formal links and relationships are broken and little is done to amend the situation. Also, there is no clear understanding of the natural resources ownership and management and therefore transition from traditional subsistence agriculture into modern one, supported by irrigation and other technically advanced methods, with a full participation of the small-holder farmers are still lacking.

Annotation:

This paper deals with relationship between irrigation and agriculture and conflicts within an irrigation system and as well between other stakeholders concerning the water. Irrigated lands are up to 2.5 times more productive compared to rain-fed agriculture. They are important element in the agriculture sector in Sub-Saharan Africa, and have been favoured by governments and donor agencies for their high rate of return. Without proper technical equipments or support negative impacts on the environment are linked to irrigation activities. Furthermore, a case study was made in Tanzania, Kiru Valley, regarding the tension between big scale and small-scale farmers as result from the water decline. The results demonstrate that the institutions do not have the power to solve the conflict. It is difficult to define the different stakeholders and the boundaries of the area that affect the amount of water in the valley.

Annotation:
A methodology was developed to conduct diagnostic performance assessment and simulation of alternative delivery scenarios in pressurized irrigation distribution networks. It consists of three components, an agro-hydrologic model able to forecast peak water demand hydrographs, a hydraulic model with capability of simulating the network behavior under different flow configurations, and a set of performance indicators for conducting assessments of performance achievements relative to specified targets. As a preliminary work, the current delivery schedule of an existing pressurized irrigation network (system 1) and the resulting effects on crop irrigation management were analyzed by simulating soil water balance and irrigation scheduling at field level. Simulations allowed analyzing the on-farm irrigation management under the current rotation deliveries, and comparing it with an alternative flexible irrigation scheduling to maximize crop yields. Results at field level were up-scaled to the entire command area of the system, showing the usefulness of soil water balance and of irrigation scheduling as analytical tools to demonstrate the inconsistency between the current water delivery and crops’ and farmers’ requirements. This preliminary work also allowed highlighting the need for modernizing the irrigation management in the first of the two study areas considered for the present research work (system 1 located in the province of Taranto, southern Italy). An existing agro-hydrological model conceived to forecast water demand hydrographs in pressurized delivery networks was enhanced through several refinements and amendments of the computation algorithms. The refined model was applied for validation at different management levels on an existing pressurized irrigation system (system 2) located in the province of Foggia, southern Italy, where water withdrawals by farmers and the main hydraulic parameters are recorded on a continuous basis for monitoring purposes. Results from validation showed that the model is capable of forecasting with good accuracy the timing of peak-demand periods, the seasonal demand irrigation volumes, as well as the hydrographs of hourly flow rates demanded by farmers during these peak periods, especially when it is applied to large multi-cropped command areas. Performance indicators, originally conceived for diagnostic assessment in canal systems, were modified for application to pressurized distribution networks, and reference standard values were proposed. These indicators were then applied for validation to the second study area (irrigation system 2), where records of water deliveries are available, and showed their usefulness for diagnostic performance assessments.

Policy makers adopt irrigated agriculture for food security, since irrigation doubles crop production. Therefore, the development of large irrigation systems has a long history in many places worldwide. Although large-scale irrigation schemes play an important role in improving food security, many schemes, especially in Africa, do not yield the expected outcomes. This is related to poor water management, which is generally due to a lack of effective evaluation and monitoring. The objective of this study, therefore, is to propose a new methodology to assess, evaluate and monitor large-scale irrigation systems. Information on irrigation indicators is needed to enable the evaluation of irrigation performance. The evaluation is the first and the most significant step in providing information about how it is performing. After reviewing extensive literature, a list of indicators related to the performance of irrigation, rainwater supply and productivity is suggested. The irrigation efficiency indicators Relative Irrigation Supply (RIS) and Relative Water Supply (RWS) are selected. Potential rainwater supply to crops can be tested based on the Moisture Availability Index (MAI) and the Ratio of Moisture Availability (RMA). Water productivity can be assessed by Crop Yield (Y) and Water Use Efficiency (WUE). However, the central problem facing large-scale irrigation schemes is always the lack of data, which calls for the development of a new method of data acquisition that allows evaluation and monitoring. Remote Sensing (RS) technology makes it possible to retrieve data across large areas. Two different approaches via RS, the Normalized Difference Vegetation Index (NDVI) and Actual Evapotranspiration (ETa), can be utilized for monitoring. The well-known Vegetation Condition Index (VCI), derived from the NDVI, is modified (MVCI) to allow a qualitative spatio-temporal assessment of irrigation efficiency. MVCI takes into account crop response to water availability, while ETa indicates whether water is used as intended. Furthermore, the assessment of the possible hydrological impact of the irrigation system should be considered in the evaluation and monitoring process. The Sudanese Gezira Scheme of 8,000 square kilometers in the Nile Basin, where performance evaluation and monitoring are absent or poorly conducted, is no exception. This research takes the large-scale irrigation of the Gezira Scheme as a case study, as it is the largest scheme, not only in the Nile Basin but also in the world, under single management. The first long-term historical evaluation of the scheme is conducted for the period 1961–2012 rather than only on a short-time scale as is the common practice. An increase in RIS and RWS values from 1.40 and 1.70 to 2.23 and 2.60, respectively, since the 1993/94 season shows decreasing irrigation efficiency. MAI and RMA for summer crops indicate a promising rainfall contribution to irrigation in July and August. The Gezira Scheme achieves low yield and WUE in comparison to many irrigation schemes of the globe. Low productivity is mainly due to poor distribution and irrigation mismanagement. This is indicated by the 15-year MVCI spatio-temporal analysis, which shows that the northern part of the scheme experiences characteristic drought during the summer crop season. Although MVCI can be considered a monitoring tool, the index does not deduct the soil water content, and water could be wasted and available in other ways (e.g. water depressions). Spatio-temporal information for ETa is required to better quantify water depletion and establish links between land use and water allocation. However, several RS models have been developed for estimating ETa. Thus, improving the understanding of performance of such models in arid climates, as well as large-scale irrigation schemes, is taken into account in this study. Four different models based on the energy balance method, the Surface Energy Balance Algorithm for Land (SEBAL), Mapping EvapoTranspiration at High Resolution with Internalized Calibration (METRIC™), Simplified Surface Energy Balance (SSEB) and MOD16 ET are applied in order to determine the optimal approach for obtaining ETa. Outputs from these models are compared to actual water balance (WB) estimates during the 2004/05 season at field scale. Several statistical measures are evaluated, and a score is given for each model in order to select the best-performing model. Based on ranking criteria, SSEB gives the best performance and is seen as a suitable operational ETa model for the scheme. SSEB subsequently is applied for summer and winter crop seasons for the period 2000–2014. Unfortunately, one of the limitations faced in the current research is the absence of validation data on a regional scale. Therefore, the assessment focuses on spatial distribution and trends rather than absolute values. As with the MVCI distribution, the seasonal ETa for the Gezira Scheme is higher in the southern and central parts than in the northern part. This confirms the robustness of the developed MVCI. To avoid using absolute values of ETa, the ratio of ETa from agricultural areas (ETagr) to the total evapotranspiration (ET) from the scheme (ETsum) is calculated. The ETagr/ETsum ratio shows a descending trend over recent years, indicating that the water is available but not being utilized for agricultural production. This study shows that SSEB is also useful for identifying the location of water losses on a daily basis. Around 80 channels are identified as having leakage problems for the 2013/14 crop season. Such information is very useful for reducing losses at the scheme. In addition, Rainwater Harvesting (WH) is addressed and found to be applicable as an alternative solution for accounting for rainfall in irrigation. It is seen that these management scenarios could save water and increase the overall efficiency of the scheme. It is possible to save 68 million cubic meters of water per year when the overall irrigation efficiency of the scheme is improved by only 1%. A level of efficiency of 75% is predicted from the proposed management scenarios, which could save about 2.6 billion cubic meters of water per year. In conclusion, the present study has developed an innovative method of identifying the problems of large-scale schemes as well as proposing management scenarios to enhance irrigation water management practice. Improved agricultural water management in terms of crop, water and land management can increase food production, thereby alleviating poverty and hunger in an environmentally sustainable manner.

This diploma thesis is focused on a large-scale irrigation embedded in the urban landscape. The main goal is to find a new concept of the large-scale irrigation system using a minimum of added electrical energy. The system is aimed at rainwater harvesting and distribution in populated areas. Part of the work is the analysis of the zoning plan of the selected locality, the design of the entire system from the accumulation of collected water to the distribution of watering to the root zone of plants. In the practical part, the proposed distribution network is calculated according to the current known equations, and the calculation is finished with the choice of a suitable diameter of the pipeline network. In addition, the work suggests possible sites for new planting of plants.

Diese Arbeit ist die erste systematische Analyse des globalen Bewässerungsbedarfs für die Bioenergieproduktion des 21. Jahrhundert. In der aktuellen Literatur finden sich diesbezüglich Prognosen von 128,4–9000 km3 yr−1. Die Zahlen hängen stark von den gewählten Parametern und Annahmen sowie den angewandten Methoden und Modellen ab. In systematischen Simulationen für die wichtigsten Parameter mit dem globalen Vegetationsmodell LPJmL, ergeben sich zwei mögliche Pfade um die Erwärmung auf 1.5°C zu begrenzen. Entweder müssten hocheffiziente Bioenergiesysteme entwickelt werden oder es müsste eine unbegrenzte Plantagenfläche bewässert werden dürfen, ohne dabei den Wasserbedarf der Ökosysteme zu berücksichtigen. Letzteres führt zu einem Interessenkonflikt, bei dem die Biomasseproduktion zur Klimarettung auf der einen Seite und der Schutz von Ökosystemen auf der anderen Seite stehen. Ein weiteres Dilemma wird sichtbar, wenn man den Wasserstress, der sich aus der zusätzlichen Bewässerung ergäbe, mit dem in einer durch ungebremsten Klimawandel um 3°C erwärmten Welt ohne Bioenergie vergleicht: In beiden Szenarien könnte (im Vergleich zu heute) der Wasserstress bis zum Ende des 21. Jahrhunderts stark steigen. Tatsächlich ergäbe sich im Bioenergie-Szenario aber sogar potenziell mehr Wasserstress als im Klimawandel-Szenario. Nachhaltiges Wassermanagement als Kombination aus Wasserentnahmebeschränkungen gemäß den Anforderungen von Flussökosystemen und verbessertem Wassermanagement auf agrarischen Nutzflächen hätte das Potenzial, diesen zusätzlichen Wasserstress zu begrenzen, wäre jedoch auf globaler Ebene schwierig zu etablieren. Diese Arbeit bestätigt, dass Bioenergieplantagen neben den Negativemissionen, die sie liefern sollen, auch zu unerwünschten Nebenwirkungen in anderen Dimensionen des Erdsystems führen könnten.
This thesis provides a first systematic assessment of 21st century global irrigation water demands for bioenergy production, for which the current body of literature projects a range of 128.4–9000 km3 yr−1. The numbers strongly depend on the parameters and assumptions chosen as well as methodologies and models applied. Systematic simulations for the identified key parameters in the dynamic global vegetation model LPJmL yield that even with optimal bioenergy plantation locations, 1.5°C can only be reached in scenarios with highly efficient bioenergy systems or strong irrigation expansion without withdrawal limitations. As a result of the large irrigation requirements, a conflict of interest arises between producing sufficient biomass and protecting environmental flows. A further dilemma is delineated by a comparison of the water stress resulting from the additional irrigation needed to limit climate change and the water stress in a 3°C warmer world without bioenergy. In both scenarios, the global area and the number of people experiencing water stress would increase severely by the end of the 21st century. The bioenergy scenario shows even higher water stress than the case of unmitigated climate change. Sustainable water management, as a combination of water withdrawal restrictions according to environmental flow requirements and improved on-field water management, has the potential to limit this additional water stress. But it would be a challenge to establish such strategies on a global scale. This work confirms that in order to provide large amounts of negative emissions, BECCS might lead to undesired deterioration of our environment and impacts for humanity. It further highlights the dilemma of rising water stress regardless whether climate change or climate change mitigation via irrigated bioenergy become a reality.

Annotation:
What happened in the post-Soviet, European grain-belt after collective farms were dissolved and in what way can we say that collective farm legacies influence agrarian developments in this region today? These are the main questions of this thesis, which is a work of critical human geography, but is also inspired by theories, methods and approaches from the social sciences, broadly defined. Territorially, the focus is Ukraine, but several articles in this thesis take a wider geographic perspective beyond Ukraine, in particular taking into account the role of Nordic investors in the agrarian sector in Ukraine and Russia. The main aim of this thesis is to examine how farms of different sizes – from small peasant farms to super large corporate farms – develop and change in post-communist circumstances. Another purpose is to reinterpret Soviet agrarian history, in light of what happened after the collapse of communism, in order to incorporate the Soviet experience in a global historical narrative, and to better understand the legacy of collective farming today. These issues are explored in four papers and a comprehensive summary. The first article examines small-scale, household “peasant” agriculture in southern Ukraine and shows the conditions and factors, which have contributed to an impressive intensification of farming in certain villages. The second article investigates large-scale, Nordic investments in Ukrainian and Russian agriculture, with the aim of explaining why many (but not all) such investments have not succeeded to the degree that investors hoped. The third paper focuses on the legacy and afterlife of Soviet-era investments in large-scale irrigation in southern Ukraine, and uses the post-Soviet reincarnation of irrigation in this region to problematize traditional narratives on Soviet environmental management in a global context. The fourth paper, with a wider historical lens, explains the link between collective farms and today’s agroholding agriculture in much of the region, while also discussing the sustainability crisis in agriculture both in a Soviet and post-Soviet context, concluding with a description of a possible and ironic (but by no means inevitable) scenario whereby post-Soviet agriculture saves global capitalism.  Theoretically, this thesis is informed by agrarian political economy; related, contemporary debates on the financialization of agriculture; and critical human geography discussions on uneven development and the geographies of difference. This thesis also is inspired by Actor Network Theory, and the view that reality is constituted by hybrid subject-objects, which are instantiated through the agency of an assemblage or network of different actors, material things, discourses, institutions, etc... While such Actor Network approaches are certainly not new, their application to Soviet and post-Soviet change is relatively new. The source material, which is the basis for the empirical approach of this thesis, is eclectic, and produced via mixed methods from different locations. Analysis is based on interviews (75 interviews in southern Ukraine, in Kyiv, and in Stockholm, plus 28 visits to household farms in one study village in southern Ukraine); participant observation (carried out in the study village in southern Ukraine and in corporate shareholder meetings mostly in Stockholm); various texts, such as corporate documents and newspaper commentary; agricultural statistics; and satellite data.  Among other conclusions, this thesis argues that, given certain factors, small-scale, household agriculture can be viable, at the same time that the concentration and consolidation of agriculture into large-scale holdings is likely to continue, at least in the short term. This thesis also highlights similarities between Soviet and capitalist agriculture in a global historical context, which is one reason that the transformation from Soviet to capitalist agriculture could occur so fast in some areas.

At the time of the doctoral defense, the following papers were unpublished and had a status as follows: Paper 3: Manuscript. Paper 4: Manuscript.

The object of this chapter is to describe and analyse the workings of labour, land, and credit markets of two villages in Bihar, four decades back, when the so-called ‘green revolution’ promised much—and certainly occupied the attention of academics and practitioners alike. The region had just started to benefit from the Kosi barrage and its extensive canal system, and new, high-yielding varieties of wheat and rice requiring irrigation were being introduced on a large scale. It is against this historical background that I examine the prevailing contractual relations in the light of the theoretical advances that were made in the decades that followed.

The discussion in this chapter is based on the premise that agricultural landscapes are the foundations of the economies, social organizations, and cultural identities of farming communities. It reviews selected archaeological districts between Sonora and the northern Rio Grande in which technologically diverse agricultural features, including trincheras, terraces, rock-bordered grids, gravel mulches, and canals, are well documented. This examination shows that large-scale field complexes, including those dependent on canal irrigation, are widespread throughout the pre-colonial North American Southwest, with some dating to the Late Archaic. Consideration of the Tewa Basin of north-central New Mexico as a case study introduces the idea that shrines are other essential agricultural landscape features, which possess the potential to contribute toward fuller understandings of farming settlement dynamics.

AbstractThe period since the Second World War has witnessed three global power shifts: one, from sovereign states relating to each other through balances of power, to inter-state organizations which pool some sovereignty and enact collective preferences; two, from states to non-state organizations, including NGOs, enormously facilitated by the internet; and three, from West to East. The World Bank has been a microcosm of these shifts. This chapter describes the interplay between some of the agents: World Bank staff; World Bank top management; World Bank Executive Directors (representatives of member governments, who formally govern the Bank); Government of India and governments of states; Indian and international (mainly UK, US, Japanese) NGOs; and the US Congress. The context is the Narmada irrigation and resettlement projects in western India from the 1970s to the 1990s. The first of the projects (Sardar Sarovar) became the subject of a large-scale opposition movement, Indian and international, which ended up forcing the World Bank to take serious responsibility for resettlement and environmental sustainability in its projects world-wide, and to create an independent inspection facility to which people who consider their welfare net harmed by a World Bank-supported project can bring complaints direct to the Bank by-passing their national government.

Abstract Indus river basin’s irrigation system in Pakistan is extremely complex, spanning over 90,000 km. Maintenance and monitoring of this extensive network demand enormous resources. This paper describes the development of a streamlined and low-cost autonomous underwater vehicle (AUV) for the monitoring of irrigation canals including water quality monitoring and water leak detection. The vehicle is a hoveringtype AUV, designed mainly for monitoring irrigation canals, with fully documented design and open source code. It has a length of 0.43 m, and a radius of 0.09 m with a depth rating of 4m. Multiple sensors have been installed onboard the AUV for monitoring water quality parameters including pH, turbidity, total dissolved solids, temperature, and electrical conductivity. A 9-DOF IMU, GY-85, is used, which incorporates an accelerometer, a gyroscope, and a magnetometer. The readings from these three sensors are fused together using direction cosine matrix algorithm, providing the AUV with the roll, pitch and yaw angles. A water pressure sensor, MS5837, gives the depth of the AUV. Four thrusters control the vehicle’s surge and heave, providing 3 DOF. The thrusters are controlled using a proportional-integral-derivative feedback control system, with IMU data and water depth being the controller’s input and the thruster’s speed as the output. The AUV is controlled by a single onboard processor, Arduino Mega 2560. A flow sensor has been installed beneath the main hull, for monitoring the changes in canal water flow and detecting potential water theft in the irrigation system. For recording underwater sounds, an indigenously developed hydrophone is placed on the AUV. The vehicle also provides information on water quality, providing the capability to identify the potential source(s) of water contamination. Detection of such events can provide useful policy inputs for improving irrigation efficiency and reducing water contamination. The AUV, being low cost and of small size, is suitable for autonomous maneuvering and water quality monitoring in the irrigation canals and can be used for monitoring irrigation networks at a large scale.
