In this article we are going to talk about the impact of climate change on production, consumption, prices and agricultural trade.
Crops need adequate land, water, sunlight and heat to grow. Global warming has altered the duration of the growing season in many parts of Europe. The periods of flowering and harvest are already several days ahead, and it is foreseeable that these changes will continue to occur in many regions.
In southern Europe, it is expected that extreme heat waves and reduced rainfall and available water will limit agricultural productivity. In some areas of the Mediterranean, the extreme hydric and thermal stress of the summer months could force the production of some summer crops towards winter.
Variations in temperatures and growing seasons could also affect the proliferation and spread of some species, such as insects, invasive weeds, or diseases, all of which could in turn affect crops.
How can we meet the growing demand for food and at the same time reduce the environmental impact of production and consumption?
Reducing the amount of food produced is not a viable solution, as the EU is one of the largest food producers in the world, and any reduction in staple crops could endanger global food security and raise food prices, it is very difficult for many groups of the population to access them.
And for agricultural lands produce more food, it is necessary to use fertilizers, which in turn contribute to climate change.
So this complex problem requires a coherent and integrated policy on climate change and food security.
To with climate change and competition for scarce resources, all agents from to the food system must transform and be more efficient both in the use of resources and reducing their environmental impacts, including greenhouse gas emissions.
We need to increase crop yields, while reducing our dependence on agrochemicals, so we must reduce food waste, consumption of food that is grown, encouraging the exploitation of resources and the emission of greenhouse gases.
In this process of change, we must not forget that farmers play an essential role in the management and maintenance of biodiversity. In addition, they are a crucial component of the rural economy.
Therefore, to address this complex problem between food production and environmental conservation, we must make the population aware so that they do not waste food and consume products, with the added value of production that respects the environment; as to farmers to produce food without harming the environment that sustains them and not waste the resources with which they work.
From Viveros PlantVid we can guarantee that in order not to waste fertilizers and have a properly fertilized soil, every year we carry out soil analysis at the beginning and at the end of each season, in order to apply the right amount of fertilizer and be able to contribute to the conservation of the environment that gives us so much joy. And not to be respectful with the environment you believe that we are doing badly, on the contrary, even with the inclement weather in our area, our plants are already showing us their first leaves.
