TO MEET THE DEMAND FOR AGRICULTURAL PRODUCTS, IT IS NECESSARY TO INCREASE THE IRRIGATED AREA BY 15 % AND MODERNISE 60 % OF THE CURRENT AREA. THE MODERNISATION AND EXTENSION OF THE IRRIGATION SYSTEM IN THE WORLD IS BEING CARRIED OUT MAINLY WITH PRESSURISED IRRIGATION SYSTEMS. THESE SYSTEMS ALLOW BETTER CONTROL OF IRRIGATION AND FERTILISER MANAGEMENT, BUT POSE THREE CHALLENGES FOR SPANISH SOCIETY: 1) TO MODERATE ENERGY CONSUMPTION, WHICH IN COMBINATION WITH THE ESCALATION OF ENERGY COSTS IS AFFECTING THE ECONOMIC VIABILITY OF MANY MODERNISED IRRIGATION AREAS AND LIMITING THE DEVELOPMENT OF NEW AREAS; 2) OPTIMISE THE GREAT VARIABILITY OF IRRIGATION PROGRAMMING PRACTICES DEVELOPED BY IRRIGATORS; AND 3) CLARIFY THE PRESENT AND FUTURE IMPACT OF THE MODERNISATION OF IRRIGATION ON DIFFUSE AGRARIAN POLLUTION AND ON HOW TO EXPRESS IT IN INDICATORS THAT SUPPORT THE IMPLEMENTATION OF ENVIRONMENTAL POLICIES. THE PROJECT WILL DEVELOP FOR FOUR YEARS RESEARCH AND DEVELOPMENT ACTIVITIES THAT ADDRESS THE THREE SPECIFIC CHALLENGES WITH DIRECT SUPPORT OF INTEREST GROUPS. WE WILL ANALYSE TECHNICAL ALTERNATIVES THAT ALLOW THE OPTIMISATION OF ENERGY CONSUMPTION BY LOWERING THE PRESSURE ON THE SPRINKLERS OF TOTAL COVERS AND OF AUTO-TRANSPORTED IRRIGATION MACHINES (PIVOTS). TECHNICAL AND AGRONOMIC OPERATION OF SPRINKLERS DESIGNED TO OPERATE AT LOW PRESSURES WILL BE CHARACTERISED IN THE FIELD. THE COMBINATION OF SIMULATION AND EXPERIMENTATION EFFORTS DURING TWO CROP CYCLES WILL ALLOW TO ESTABLISH THE TECHNICAL, ECONOMIC AND PRODUCTIVE POSSIBILITIES OF OPERATING AT LOW PRESSURE SYSTEMS IN TOTAL COVERAGE AND IRRIGATION MACHINES (PIVOTS). THE EFFECT OF THESE IMPROVEMENTS ON PLOTS AND COLLECTIVE NETWORKS WILL BE ANALYSED. IRRIGATION MANAGEMENT ALTERNATIVES FOR A CORN CROP WILL BE EVALUATED EXPERIMENTALLY. THESE ALTERNATIVES WILL BE BASED ON THE FREQUENCY AND TIMING (DAY/NIGHT) OF THE IRRIGATION. AGRONOMIC TRIALS WILL ILLUSTRATE THE EFFECT OF THE MANAGEMENT VARIABLES OF IRRIGATION BY ASPERSION ON MICROCLIMATE, PLANT GROWTH AND DEVELOPMENT, FOLIAR IONICA ABSORPTION, SOIL MOISTURE REGIME, PHOTOSYNTHESIS AND YIELD IN A CORN CROP. THIS WILL ALLOW FOR THE ESTABLISHMENT OF MANAGEMENT GUIDELINES THAT MAXIMISE WATER PRODUCTIVITY. FINALLY, SCIENTIFIC AND TECHNOLOGICAL DEVELOPMENTS WILL BE IMPLEMENTED TO IMPROVE THE CLOSURE OF WATER BALANCES IN EXPERIMENTAL BASINS. THESE DEVELOPMENTS CONTEMPLATE THE ESTIMATES OF REAL EVAPOTRANSPIRATION WITH SATELLITE REMOTE DETECTION, THE CALCULATION OF THE COEFFICIENTS OF CULTIVATION FROM THE THERMAL INTEGRAL, AND THE MONITORING OF THE FREATICO LEVEL FOR A BETTER QUANTIFICATION OF THE SUBTERRANEAN FLOWS. THE PRECISION OF INDICATORS OF DIFFUSE AGRICULTURAL POLLUTION IS BASED ON THE QUALITY OF WATER BALANCES. THESE INDICATORS WILL BE APPLIED TO THE CHARACTERISATION OF THE ENVIRONMENTAL IMPACT OF AREAS IRRIGATED BY ASPERSION IN THE EBRO VALLEY. THE ANALYSIS OF THE BALANCES WILL BE COMBINED WITH THE USE OF SIMULATION TOOLS TO ESTABLISH DIFFUSE POLLUTION CONTROL STRATEGIES AT PLOT AND WATERSHED SCALE. DSSAT AND SWAT MODELS WILL BE USED TO ANALYSE FUTURE SCENARIOS BASED ON CHANGES IN THE USE OF PRODUCTION INPUTS, WATER SCARCITY AND CLIMATIC CHANGE. IN IMMEDIATE FOLLOW-UP ACTIONS, THE ACTIVITIES OF THE PROJECT WILL GENERATE TECHNICAL AND REGULATORY INNOVATIONS THAT GO BEYOND THE CURRENT CROSSROADS. (English) | |||||||||||||||

PARA ATENDER LA DEMANDA DE PRODUCTOS AGRICOLAS RESULTA NECESARIO INCREMENTAR LA SUPERFICIE REGADA EN UN 15% Y MODERNIZAR EL 60% DE LA SUPERFICIE ACTUAL. LA MODERNIZACION Y EXTENSION DEL REGADIO EN EL MUNDO SE ESTAN REALIZANDO FUNDAMENTALMENTE CON SISTEMAS DE RIEGO PRESURIZADO. ESTOS SISTEMAS PERMITEN UN MEJOR CONTROL DEL MANEJO DEL RIEGO Y LOS FERTILIZANTES, PERO PLANTEAN TRES RETOS PARA LA SOCIEDAD ESPAÑOLA: 1) MODERAR EL CONSUMO DE ENERGIA, QUE EN COMBINACION CON LA ESCALADA DE COSTES ENERGETICOS ESTA AFECTANDO A LA VIABILIDAD ECONOMICA DE MUCHAS ZONAS DE REGADIO MODERNIZADAS Y LIMITANDO EL DESARROLLO DE NUEVAS ZONAS; 2) OPTIMIZAR LA GRAN VARIABILIDAD DE PRACTICAS DE PROGRAMACION DE RIEGOS QUE HAN DESARROLLADO LOS REGANTES; Y 3) ESCLARECER EL IMPACTO PRESENTE Y FUTURO DE LA MODERNIZACION DE REGADIOS SOBRE LA CONTAMINACION AGRARIA DIFUSA Y SOBRE LA FORMA DE EXPRESARLA EN INDICADORES QUE DEN SOPORTE A LA IMPLEMENTACION DE POLITICAS AMBIENTALES. EL PROYECTO VA A DESARROLLAR DURANTE CUATRO AÑOS ACTIVIDADES DE INVESTIGACION Y DESARROLLO QUE ABORDAN LOS TRES RETOS ESPECIFICOS CON APOYO DIRECTO DE GRUPOS DE INTERES. SE ANALIZARAN ALTERNATIVAS TECNICAS QUE PERMITAN LA OPTIMIZACION DEL CONSUMO ENERGETICO REBAJANDO LA PRESION EN LOS ASPERSORES DE COBERTURAS TOTALES Y DE MAQUINAS DE RIEGO AUTOTRANSPORTADAS (PIVOTES). SE CARACTERIZARA EN CAMPO EL FUNCIONAMIENTO TECNICO Y AGRONOMICO DE ASPERSORES DISEÑADOS PARA OPERAR A BAJAS PRESIONES. LA COMBINACION DE ESFUERZOS DE SIMULACION Y DE EXPERIMENTACION DURANTE DOS CICLOS DE CULTIVO PERMITIRA ESTABLECER LAS POSIBILIDADES TECNICAS, ECONOMICAS Y PRODUCTIVAS DE OPERAR A BAJA PRESION SISTEMAS EN COBERTURA TOTAL Y EN MAQUINAS DE RIEGO (PIVOTES). SE ANALIZARA EL EFECTO DE ESTAS MEJORAS EN PARCELA Y EN REDES COLECTIVAS. SE EVALUARAN EXPERIMENTALMENTE ALTERNATIVAS DE MANEJO DEL RIEGO PARA UN CULTIVO DE MAIZ. ESTAS ALTERNATIVAS ESTARAN BASADAS EN LA FRECUENCIA Y MOMENTO (DIA/NOCHE) DEL RIEGO. LOS ENSAYOS AGRONOMICOS ILUSTRARAN EL EFECTO DE LAS VARIABLES DE MANEJO DEL RIEGO POR ASPERSION SOBRE EL MICROCLIMA, EL CRECIMIENTO Y DESARROLLO DE LAS PLANTAS, LA ABSORCION IONICA FOLIAR, EL REGIMEN DE HUMEDAD DEL SUELO, LA FOTOSINTESIS Y EL RENDIMIENTO EN UN CULTIVO DE MAIZ. ESTO PERMITIRA ESTABLECER PAUTAS DE MANEJO QUE MAXIMICEN LA PRODUCTIVIDAD DEL AGUA. FINALMENTE, SE IMPLEMENTARAN DESARROLLOS CIENTIFICOS Y TECNOLOGICOS PARA MEJORAR EL CIERRE DE LOS BALANCES DE AGUA EN CUENCAS EXPERIMENTALES. ESTOS DESARROLLOS CONTEMPLAN LAS ESTIMAS DE EVAPOTRANSPIRACION REAL CON TELEDETECCION SATELITAL, EL CALCULO DE LOS COEFICIENTES DE CULTIVO A PARTIR DE LA INTEGRAL TERMICA, Y EL SEGUIMIENTO DEL NIVEL FREATICO PARA UNA MEJOR CUANTIFICACION DE LOS FLUJOS SUBTERRANEOS. LA PRECISION DE LOS INDICADORES DE CONTAMINACION DIFUSA AGRARIA SE BASA EN LA CALIDAD DE LOS BALANCES DE AGUA. ESTOS INDICADORES SE APLICARAN A LA CARACTERIZACION DEL IMPACTO AMBIENTAL DE ZONAS REGADAS POR ASPERSION EN EL VALLE DEL EBRO. EL ANALISIS DE LOS BALANCES SE COMBINARA CON LA UTILIZACION DE HERRAMIENTAS DE SIMULACION PARA ESTABLECER ESTRATEGIAS DE CONTROL DE LA CONTAMINACION DIFUSA A ESCALA DE PARCELA Y DE CUENCA HIDROLOGICA. SE UTILIZARAN LOS MODELOS DSSAT Y SWAT PARA ANALIZAR ESCENARIOS FUTUROS BASADOS EN CAMBIOS EN EL USO DE INSUMOS DE PRODUCCION, ESCASEZ DE AGUA Y CAMBIO CLIMATICO. EN ACTUACIONES INMEDIATAMENTE POSTERIORES, LAS ACTIVIDADES DEL PROYECTO SERVIRAN PARA GENERAR INNOVACIONES TECNICAS Y NORMATIVAS QUE SUPEREN LAS ENCRUCIJADAS ACTUALES. (Spanish)

TO MEET THE DEMAND FOR AGRICULTURAL PRODUCTS, IT IS NECESSARY TO INCREASE THE IRRIGATED AREA BY 15 % AND MODERNISE 60 % OF THE CURRENT AREA. THE MODERNISATION AND EXTENSION OF THE IRRIGATION SYSTEM IN THE WORLD IS BEING CARRIED OUT MAINLY WITH PRESSURISED IRRIGATION SYSTEMS. THESE SYSTEMS ALLOW BETTER CONTROL OF IRRIGATION AND FERTILISER MANAGEMENT, BUT POSE THREE CHALLENGES FOR SPANISH SOCIETY: 1) TO MODERATE ENERGY CONSUMPTION, WHICH IN COMBINATION WITH THE ESCALATION OF ENERGY COSTS IS AFFECTING THE ECONOMIC VIABILITY OF MANY MODERNISED IRRIGATION AREAS AND LIMITING THE DEVELOPMENT OF NEW AREAS; 2) OPTIMISE THE GREAT VARIABILITY OF IRRIGATION PROGRAMMING PRACTICES DEVELOPED BY IRRIGATORS; AND 3) CLARIFY THE PRESENT AND FUTURE IMPACT OF THE MODERNISATION OF IRRIGATION ON DIFFUSE AGRARIAN POLLUTION AND ON HOW TO EXPRESS IT IN INDICATORS THAT SUPPORT THE IMPLEMENTATION OF ENVIRONMENTAL POLICIES.
