During centuries Galicia was a thriving land of olive groves with unique varieties in the world. What changed it is still a mystery

If you think of Galicia, in their landscapes, probably the first thing that comes to mind is your sinuous coastline, your beaches and cliffsserpentant channels such as the Sil River as it passes through the Ribeira Sacra, castrosleafy Atlantic forests, grasslands with cattle … The list is extensive (and diverse), but probably the olive groves are not included, a stamp that usually associates more to the peninsular south. It was not always the case. There are indications that Galicia had an interesting relationship with the cultivation of the olive trees that can go back to the times of Gallaecia. When that link declined and what were the causes of the sunset and that the olive tree does not prosper are issues that still generate debate among experts. Olivos in Galicia? Yes. And its relationship comes from afar, it is rich and has inspired researchers who have identified in Galician lands A wide catalog of unique native olive varieties in the world. The indications are suggestive, although I recognized years ago The historian Lourenzo Fernández during a days held in Pontevedra and focused precisely on the olive trees, shadows are still in that bond. “There is no specific historical, nor bibliographic research that will address the presence of Olivos in Galicia,” explained. Looking at the Roman Gallaecia. The link between Galicia and the olive tree can be traced at least Roman Gallaecia. In the middle of the last century, during an excavation in an area of ​​Vigo that is called precisely Oliveira, archaeologists discovered a Roman deposit which included bricks, bases, a mortar, mills, amphorae … and an oil press, among other vestiges. “It is thought that it could be a villa or factoring by the oleic press found, the only example appeared in Galicia. The possible relationship between the obtaining of oil and the olive tree in Vigo was also pointed out, in ancient times, with the activity that would give name to the place,” Explain The Quiñones de León Museum, where the remains rest, although those responsible recognize that the scarcity of remains of oil and amphorae lamps in the environment can be interpreted as a “lack of consumption.” Leaving its mark. Vigo’s is not the only proof of the interesting historical link between Olivo and Galicia. There are ethnographic studies that show that in the region there are dozens and tens of place names related to olive trees, olive groves, oil and similar references. Years ago at least 70 were counted. The CSIC has also identified about twenty varieties of native olive trees, unique in the world, and there is a record of specimens standing from the 18th century, the oldest in the community that are still alive, according to a analysis done years ago. A “very present” crop in Galicia. The presence of olive trees in Galicia put it in value since The industry itself to the organisms public. “The olive culture was very present in Galicia since the time of the Romans. The primitive settlers ate olives, although they did not know the methods of extraction of the oil. The Romans are those that introduce the knowledge of these methods that are transmitted by the territory. Galicia became one of the conquered territories of which the most oil went out to Rome in the second and second centuries.” They detail From Ribeira Sacra tourism. In the community it is not strange either find References of traditional oil mills in which the fruit was used. “In Galicia there were olive plantations, in some cases, of large dimensions, that if we follow some sources they would have been possible thanks to the introduction of this crop in our land by the Romans,” historian Felipe Aira explained in January An article of The voice of Galicia that he remembers how the Jews and Judeoconvers used the ‘liquid gold’ in their kitchens and at least part of the olive trees were preserved in the properties of the church, even after their decline in Galicia, for their value for the elaboration of the liturgical oils. And the great unknown arises. All The chronicles that tell the link between the Olivos and Galicia end up reaching the same question: what explains that their cultivation ends up losing weight? Why Galicia It ceased to be an olive grove? Or even simpler … Why didn’t they remain expanding until they occupy a relevant weight in the Galician fields? As Lourenzo remembered in 2018, shadows are still and a long way to explore “about the presence of Olivos in Galicia. His story is splashed with legends and inaccuracies, he said recently A chronicle Fiftymil, but is usually pointed to a complex sum of political, economic, demographic reasons and the reality of agricultural farms.

When the history of olive tree is explained in Galicia there are two names that are usually repeated: the first, the Catholic Monarchs; The second, Count Duke of Olivares. An extended theory ensures that the former, Fernando II of Aragon and Isabel I of Castilla, adopted a series of decisions about taxes and reorganization that punished the Galician plantations and favored that olive trees be started in the region. But … why? There are those who say that the purpose was to favor the repopulation and crops of the newly reconquered lands of the Peninsular South. Others argue that in their decision, more political factors would have weighed and that when the Galician olive trees sought to penalize the territory and their aristocracy. The “Doma and castration from Galicia, “said the intellectual of the twentieth century, Alfonso Daniel Rodríguez Castelao about the policies of the Catholic Monarchs. The context is key and was marked by the defeat of Juana la Beltraneja, and therefore of the nobility that supported her in her cause, and the Irmandiños rebellion that developed in Galicia. The shadow of olive groves. The theory is even more extended that if there … Read more

We have created 200 sorghum varieties. It looks like an anecdote but it has the potential to change world food

The sorghum It is not one of the best known crops for the Mediterranean diet but there are those who predict a brilliant future to this cereal. One of his strengths is not in what he has except what he lacks: gluten. Another feature that could bring this food closer to our dishes is in its resistance. Or that’s what some researchers are looking for. To hunt varieties. Researchers such as Melinda Yerka, from the University of Nevada in Reno, responsible for the development of 200 variants of this seed. The objective is to create drought more resistant varieties capable of rooting and producing livestock and people in a changing climate context. Fifth in discord. Sorghum is not a regular of our dishes but it is one of cereal crops most important worldwide after the “great three” (rice, wheat and corn) and barley. FAO (the United Nations Food and Agriculture Organization) esteem that in 2022 there were about 58 million tons of this grain, being the largest producers Nigeria, Sudan and the United States. In the US, the sorghum is mainly used to feed cattle, but this grain can be and is widely used as food. Sorghum is a known gluten -free cereal of the gastronomies of several countries in Asia and Africa, the latter continent from which it is originally. This cereal can even be used fermented as wheat and barley to Create beers or in the preparation of biofuels. Great tolerance. Beyond the uses to which this grain can be dedicated, if something highlights the Yerka team is the resistance of the new variants created. The preliminary studies of the team highlighted their great tolerance against drought although some variants with high levels of protein and digestible starch also highlighted. Based on these first analyzes, the team estimates that the seeds achieve optimal development when they receive between 50.8 and 63.5 centimeters of annual water, considerably less than what crops such as alfalfa require. Prepared for semi-aridity. The new varieties have been created thinking about the semi-aridity conditions of the west of the United States but their developers believe that they could serve farmers from other areas with similar climates worldwide to have at their disposal a new food alternative for their cattle. An alternative with the advantage of requiring lower water use. “Many foods devised for the dairy industry in the US face a fall or variable productions due to late frosts, floods, heat and droughts associated with climate change, which underlines the need for more resilient alternatives that can prosper in conditions of change in the climate,” he explained In a press release Yerka herself. Market the advance. The Yerka Laboratory at Nevada University has been operating Since 2017 But since 2023 it has its own project for the marketing of the fruits of its work, Yerka Seeds.
