Climate change is urgent and Mediterranean agriculture needs to protect itself. The greater than possible discount in rainfall within the Mediterranean and the uncertainty that marks the way forward for water transfers in Spain have led the Generalitat Valenciana to redouble the efforts to discover strategies to cut back water consumption in agriculture and the fruit and vegetable sector, sustenance of 100 thousand households solely within the province of Alicante. Hydroponic cultivation is introduced as a superb various to face international warming.
The Valencian Institute of Agricultural Analysis (IVIA) has turn out to be in recent times a sort of “Silicom Valley & rdquor; agricultural, through which a staff of scientists works, as within the agricultural station of Elche, to obtain the miracle that farmers can keep their crops in amount and high quality by lowering water consumption.
There they work with the winery, pomegranate, artichokes, persimmon and citrus, searching for varieties that require much less chilly hours.
The Ministry for the Ecological Transition, in the meantime, satisfied that we should search options to the Tajo-Segura switch, has simply introduced to the irrigators of Castilla-La Mancha, Murcia and Almería, a funding of 1,600 million euros within the subsequent 5 years.
The cash will likely be used to enhance irrigation and purification strategies and, above all, to optimize the desalination of sea water, a controversial useful resource due to its value, particularly for agriculture, however which is an important a part of Teresa’s roadmap. Riverbank.
Rainfall will likely be decreased by 30% within the subsequent 50 years
The omens are worrying: within the subsequent 50 years, rains will likely be decreased by 30%, the provision of water from transfers is reducing, and desalinated water has prohibitive costs.
To forestall the results of this example, the Valencian Neighborhood Division of Agriculture works on two strains: irrigation referred to as “deficit & rdquor; and the advance of strategies to combat salinity. Stopping the results that climate change could have on Mediterranean agriculture is the target of the IVIA.
Enrique Moltó, director of the Institute, explains that the strains of labor deal with 4 areas. The Discount of water consumption with crop trials and the optimization of irrigation towards salinization of soils; the manufacturing of patterns and varieties resistant to drought, as is the case of mandarin, and salinity (pepper and persimmon); the analysis on genes that affect resistance to drought and salinity; and the manufacturing of fruit varieties (peaches and nectarines), that require much less chilly hours.
“Deciduous bushes want, for instance, to accumulate through the winter a minimal variety of hours of chilly for the break from relaxation and begin the exit from lethargy. Every species wants to accumulate that minimal quantity & rdquor ;, explains Moltó.
Concerning deficit irrigation, it consists of “accustoming & rdquor; to the plant to obtain water when it actually wants it, since there are intervals of the 12 months when “it is not wanted or the necessity is minimal & rdquor ;, Moltó emphasizes.
Goal, to obtain crops resistant to soil salinization
Comparable work is being carried out to obtain crops resistant to soil salinization, a phenomenon instantly associated to the rise in temperatures and the lower in rainfall. “It is about incorporating cultivation patterns that make it potential create crops extra resistant to saline soil. We work with the Niber pepper, persimmons and the Nero number of clementine & rdquor ;, indica.
One other method that positive factors worth is the cultivation virtually with out soil. Via the hydroponic system -cropping on substrates as a substitute of soil-, crops take up minerals via ions dissolved within the water and minerals discovered inside them.
Beneath pure situations, the soil acts as a reservoir of mineral vitamins, however in itself it is not important for the plant to develop. When the mineral vitamins within the soil are dissolved in water, the roots of the plant are in a position to take up them. And if they’re included into the plant’s water provide, the soil is now not required for it to thrive.
This observe is reaching an amazing growth in international locations the place situations for agriculture are adversarial. Combining hydroponics with good greenhouse administration, yields are a lot greater than these obtained in open-air crops.
The Guilló household will be thought-about a pioneer in making use of the hydroponic system to their plantations, since they’ve been efficiently making use of the method to their tomato crops in Campo de Elche for twenty years.
A lot tastier and extra ecological tomatoes
“We work in a greenhouse and what we’ve achieved is to domesticate with half the land of standard cultivation, therefore the necessity for water is additionally decreased by half. The one which is left over, by not having to infiltrate the earth, is redirected to our conventional crops overseas, such because the artichoke & rdquor ;, underlines Clara Guilló, whose tomato manufacturing reaches the markets of the province day by day of the anus.
“Thanks to sensors we all know the quantity of water that is wanted always, therefore the saving is vital. As well as, these tomatoes are a lot tastier and extra ecological as a result of their cultivation additionally requires much less therapies & rdquor ;, he provides. The system will be utilized to all varieties of greens.
The water deficit that suffers a big a part of the territory and the rising competitors within the makes use of of water, drive the rationalization of using movement for irrigation, modernizing the buildings and incorporating extra environment friendly irrigation techniques.
On this sense, a pilot telemonitoring of soil moisture is being carried out within the Valencian Neighborhood. Within the El Marquesat area, within the province of Valencia, a undertaking has been launched to enhance the administration of an space of roughly 2,000 hectares with pre-existing localized irrigation.
