Pollination and Agriculture
Importance of the pollination for a sustainable agriculture
The pollination is the process through what pollen is transferred from the masculine organ of the flower towards the feminine one. This process can be realised by abiotic agents, as the wind or the water; or by biotic agents, as bees, butterflies, flies or birds. In all the cases, one is a little while nails for the formation of seeds and fruits of multiple species, including which they take place in agricultural cultures.
Esteem that around 35% of the agricultural cultures in the world depends on the pollination to obtain a successful production. At the same time, it is considered that a 70% of the cultures improve their production thanks to the visit of pollenizers.
The dependency in major or measured minor of the pollination varies according to each species: the cultures of massive consumption, as the maize, the rice or the wheat, pollinate by anemophily, that is to say, through air or the wind. Species as the cacao, vanilla, zapallo or the watermelon inevitably need the presence of agents biotic pollenizers, since, otherwise, its production would practically be null.
Beyond the degree of dependency of each species, he is doubtless that good part of the foods that consume the human beings to survive would not exist if not outside by the pollination. For that reason, agriculture needs to take care of the agents pollenizers, since its absence could produce a significant reduction of all the agricultural production.
What can make agriculture to guarantee the presence of pollenizers?
The key for the survival of the polinizadoras species is the presence of diverse ecosystems, since all the agents do not pollinate the same plants and flowers. When promoting the biodiversity, incorporating multifunctional landscapes to the cultures and to impel the heterogeneity, optimal conditions offer so that each agent pollenizer obtains foods and owns specific habitats.
In conclusion, to reach a sustainable agriculture, it is fundamental to consider the needs of the agents pollenizers, since without them the agricultural production would be reduced drastically and been very difficult to generate the volume of foods that the human beings need to survive.
