Irrigation: Advancements and State of the Art [Farmer]

Introduction

Population increase and the improvement of living standards brought about by development will result in a sharp increase in food demand during the next decades. At the same time, water inputs will have to be reduced in response to water scarcity and environmental concerns. Water productivity is projected to increase through gains in crop yield and reductions in irrigation water. In order to meet these projections, irrigation systems will have to be modernized and optimized.^[1] Best management practices need to be adopted, while precision agriculture can provide the right tools and techniques for optimized water use. Meteorological conditions’ monitoring, soil moisture sensing and automated systems for irrigation can bring the desirable results.

4. Vaisala hydrometeorological stations

Due to the growth of population throughout the world, there is pressure to improve methods and practices of agriculture in order to increase crop yields. The main concern of productive agriculture is related to the effective and efficient supply of water that is easily available for crop fields. The major uncertainty with the water supply is associated with unevenly distributed precipitation and with the impacts of climate change on water availability.
Faulty irrigation scheduling will lead to waste of water. Therefore it is crucial to know how much water there is and how much water will be available for irrigation.

Vaisala hydro meteorological stations are used to monitor the amount of precipitation and to measure water levels in reservoirs to provide real-time information on availability of water for irrigation. In addition, Vaisala systems calculate directly evapotranspiration thus providing an indication about the amount of water needed for the plants.

1. MOSES

The main objective of MOSES is to put in place and demonstrate at the real scale of application an information platform devoted to water procurement and management agencies (e.g. reclamation consortia, irrigation districts, etc.) to facilitate planning of irrigation water resources, with the aim of:
• saving water;
• improving services to farmers;
• reducing monetary and energy costs.

To achieve these goals, the MOSES project combines in an innovative and integrated platform a wide range of data and technological resources: EO data, probabilistic seasonal forecasting and numerical weather prediction, crop water requirement and irrigation modelling and online GIS Decision Support System.
Spatial scales of services range from river basin to sub-district; users access the system depending on their expertise and needs. Main system components are:
1. early-season irrigated crop mapping
2. seasonal weather forecasting and downscaling
3. in-season monitoring of evapotranspiration and water availability
4. seasonal and medium/short term irrigation forecasting

Four Demonstration Areas will be set up in Italy, Spain, Romania and Morocco, plus an Indian organization acting as observer. Different water procurement and distribution scenarios will be considered, collecting data and user needs, interfacing with existing local services and contributing to service definition. Demonstrative and training sessions are foreseen for service exploitation in the Demonstration Areas.
The proposed system is targeting EIP on Water “thematic priorities” related to increasing agriculture water use efficiency, water resource monitoring and flood and drought risk management; it will be compliant to INSPIRE. This SME-led project address to the irrigated agriculture users an integrated and innovative water management solution.^[11]

2. EFFIDRIP

EFFIDRIP is being developed as smart irrigation system that answers future agricultural needs. EFFIDRIP will represent an automatic irrigation scheduler and management support system that permits more efficient use of water, fertilizers and energy in drip irrigated tree crops.

EFFIDRIP is an ICT-based tool for supporting the management and supervision of irrigation and fertigation. In particular, it has been conceived for localized irrigation systems in tree crops although its use could be extended to further scenarios. Its overall objective is to offer a cost-effective tool that provides the end-users (farmers or technicians) effortless irrigation and fertilization management, as well as easy and reliable supervision of the state of the irrigation system. EFFIDRIP aims at relieving farmers from most of the tasks involved in acquiring data, re-scheduling, reprogramming and supervising the application of efficient irrigation.

The EFFIDRIP system complements the functionalities of current irrigation and fertigation control equipment by making them part of a higher level system based on ICT. The role of that high level system is the integration of data and information from multiple sources for their usage in automated scheduling decisions and supervision. It can also facilitate user interaction with the system and communication between people involved in the process. The irrigation controller remains as a key component for the execution of irrigation and fertigation schedules with some autonomy.

What really makes the difference is that those schedules will be updated remotely once a day for each irrigation sector. For each subsequent application, the precise crop water and fertilizer needs will be estimated as a function of weather conditions, the soil and crop water status assessed by sensors, as well as to the productive and environmental goals by the farmer. For this purpose, weather data and sensor measurements are combined in base of state-of-the-art agronomic knowledge. Machine-to-machine communications and design of the application aim to reduce the need for user intervention in operational tasks and instead focus its participation in strategic decisions.^[12]
