And Control

Market vis-à-vis command and control approaches have been widely adopted in natural resource and environmental management since the 1980s. Adoption of markets in managing irrigation water resources is also emerging. It has been argued that markets are ineffective in managing the demand for irrigation water due to very low price elasticity. Most studies have been based on mathematical models simulating water markets and not on observed prices and quantities in real water markets since such data are rarely available. In Oman, perhaps in response to the extreme scarcity of water, elaborate water demand management institutions emulating markets have evolved and have been used for centuries. Water entitlements are leased based on prices through a community auction. The traded quantities of water and related prices have been recorded. This study uses this unique data set to estimate the elasticity of irrigation water. A log function on quantity and price of irrigation water is used with dummy variables on time and type of irrigation system. The price elasticity varies from -0.10 to -0.28, depending on the specifications of the econometric model. These estimates are higher than most estimates reported in past studies, indicating the efficacy of the indigenous market-based irrigation water management institution adopted in Oman.

The available water condition is smaller than the need of irrigation water of agricultural land that is needed is an expression of conflict in the field. To overcome this is by the regulation of several parameters, including the regulation of planting schedule and reduction of land area. The model of irrigation system used is based on the optimum area regulation of cultivable land. Parameters used to overcome this problem are planting schedule, land failure risk and k factor. The k factor is the ratio of water availability to the water requirement. The output of this system is optimal net benefit based on alternative land area of irrigation. The result of the formula will show the optimal amount of land that produces the optimal net benefit based on certain cropping schedule and certain effective rainfall. The system will also demonstrate that optimization will be achieved if there is a water balance between the availability and demand for irrigation water. The system referred to in this study is a dynamic system. The purpose of this research is to make early design of dynamic system to optimize agricultural irrigation system. The results obtained in this research form the formation of feedback loops and interaction between loops with each other on irrigation systems of agricultural land.

This paper reviews Jordan's relatively short experience gained since participatory irrigation management (PIM), was introduced with due consideration of the traditional social and cultural merits. The introduction of PIM was a meaningful partial shift in the paradigm of operation of the Jordan Valley irrigation system that has been undertaken by government agencies since its staged implementation between 1960 and 1988. The Jordan Valley Authority (JVA) of the Ministry of Water and Irrigation, among other responsibilities, is the current government agency in charge of operation and maintenance of the irrigation system. The advantages of the introduced mode of operation, the PIM, especially in an environment of perpetual irrigation water shortage, are presented. The paper further discusses the multi-dimensional facets of PIM expressed by the representation of users’ community and by the level of representation as well as the interaction between the targeted groups and the government and highlights the virtues of “learning while implementing” in which midcourse corrections can be made in order to arrive at a state of equilibrium between the various stakeholders. The adoption of traditional cooperation as a basis for setting up water users associations (WUAs), is presented. The emergence of PIM as a competitor to management contracts adopted in municipal water and wastewater management in Jordan is touched upon and the dynamics of PIM application in the Jordan Valley, including the division of labor between the WUAs and JVA, is described.

The irrigation system in rainfed lowland is done through a water gate (Temuku). Farmers should always control the height of the water and wetland gates during the dry and rainy seasons. This is due to delays in control which can cause the fields to dry or flooded. In this research, water warning system and Temuku control (water gate) for irrigation of paddy field. This tool can provide water level information and can also close or open the irrigation water gate through an SMS. Components used in the manufacture of water alert warning systems and the control of Temuku (sluice gates) for irrigation rice fields are arduino UNO, ultrasonic sensors, SIM 900 and servo motors. From the results of tests that have been done, it can be concluded that the system of water warning and control of Temuku (sluice gate) for irrigation of paddy field has been able to provide water level information to farmers and also the system has been able to control the irrigation water gate according to the input given by SMS.

At the stage of water treatment for irrigation systems, the efficiency capture coarse and fine mechanical impurities, as well as oil products and organic compounds affects the reliability of the equipment of the irrigation network and the safety of energy exchange processes in irrigated agricultural landscapes. The violation of work irrigation system can cause disruptions in irrigation schedules of agricultural crops, crop shortages, degradation phenomena on the soil and ecological tension. For the combined irrigation system, a water treatment unit has been developed, representing a hydrocyclone apparatus with a pipe filter in the case. For the capacity of 250 m3/h the main geometrical dimensions of hydrocyclone have been calculated. To organize the capture petroleum products and organic compounds, it has been proposed a modernization of a hydrocyclone unit, consisting in dividing the cylindrical part of the apparatus into two section. The first is section is for input irrigation water, the second one is for additional drainage of clarified irrigation water after sorption purification by the filter, placed on the disk and installed coaxially with the drain pipe and the pipe filter.

HIGHLIGHTSUniversity extension has been playing a larger role, serving a larger number of irrigated farms.Extension programs in irrigation water management (IWM) have been transitioning away from lectures and field tours as the primary means of knowledge transfer.New IWM programs focus on experiential learning, development of practitioner networks, and industry participation.Abstract. Promotion and adoption of irrigation water management (IWM) technology, tools, and best management practices are important as water availability concerns are addressed. Traditional extension programs have relied on lecture presentations, field tours, fact sheets, and on-station demonstrations to promote IWM practices and tools. However, these platforms tend not to provide the experience and opportunity for growers to identify and become comfortable with innovative solutions, such as new technology. To address these challenges and to appeal to an ever-changing client base, innovative and locally relevant extension and outreach programs have been devised to engage and educate growers. This article describes some of these programs that extend beyond previous traditional programs to connect growers with IWM. Keywords: Demonstrations, Experiential learning, Grower competition, Outreach, Practitioner networks.
