Given the implication that Plantae has in optimizing the use of water, we are going to try to explain what the water footprint <\/strong> is and how we can improve its indicator with an adequate precision agriculture <\/strong>.<\/p>\n\n\n\n

What is the water footprint?<\/h2>\n\n\n\n

Arjen Hoekstra<\/strong> defini\u00f3 en 2002 la huella h\u00eddrica<\/strong> como \u201cel volumen de agua necesario para la obtenci\u00f3n de los productos y servicios consumidos por los habitantes de un pa\u00eds, de una regi\u00f3n o por una persona”.<\/strong>
Es decir, el agua que necesitamos para producir todo lo que consumimos, para la higiene, la limpieza y cualquier servicio que utilicemos. Por tanto tener un indicador que mida esta cantidad ser\u00e1 importante para regular los recursos h\u00eddricos.<\/p>\n\n\n\n

Types of water <\/a> we use<\/h2>\n\n\n\n

The types of water are distributed by colors:<\/p>\n\n\n\n

Blue water: <\/strong> is the water that comes from rivers, lakes and that we mainly use for irrigation or animal consumption.<\/p>\n\n\n\n

Green water <\/strong>: it is the water of rain, snow or hail. It goes directly to agriculture. Naturally nourishes all kinds of agricultural elements. Cleanses the atmosphere and seeps into everything. It also accumulates in rafts that we can then use for irrigation.<\/p>\n\n\n\n

Gray water <\/strong>: the set of water that we need to dilute pollutants, excess fertilizers and that can be reused at times.<\/p>\n\n\n\n

Golden yellow water <\/strong>: the one that we desalinate with chemical products and is normally used for urban use in cleaning services. It is not suitable for human consumption and little for agricultural use due to the agronomic problems that can be generated, apart from the very high cost.<\/p>\n\n\n\n

In the diagram we indicate that the four types of water give rise to a total that is used in different ways, the majority in agriculture and livestock.<\/p>\n\n\n\n

Formula to calculate the Water Footprint of a specific crop or plot<\/h2>\n\n\n\n

It is necessary to know some concepts that lead to the calculation of the water footprint.<\/p>\n\n\n\n

HH (PARCELA) = AV(PROD) + AV(IMPORT) <\/span><\/h3>\n\n\n\n
\"C\u00e1lculo<\/figure>\n\n\n\n

HH (total) <\/strong> <\/span> is the total volume of water in a country for distribution and consumption.<\/p>\n\n\n\n

AV (PROD) OR VIRTUAL WATER <\/span>: <\/strong> is the water consumed for the production of the harvest.<\/p>\n\n\n\n

strong> AV (IMPORT) OR IMPORTED WATER <\/span>: <\/strong> is the water consumed by the inputs of the plot or post-harvest production processes.<\/p>\n\n\n\n

The Water Footprint (HH) is the quotient between HH (plot) and the total kilos harvested.<\/strong><\/span><\/p>\n\n\n\n

Plantae involved with precision agriculture to optimize the water footprint with sensors \/ probe<\/h2>\n\n\n\n

All the amount of water that we use or consume is not destroyed, it is transformed. One evaporates, another passes to the crops, but all within a cycle as we see in the diagram.<\/p>\n\n\n\n

Various studies measure the amount of water needed by crops that are the largest consumers of water on the planet.<\/p>\n\n\n\n

The water that we can control the most is irrigation, which can be blue <\/strong> from rivers, swamps, lakes or green <\/strong> due to accumulation in ponds and direct irrigation.<\/p>\n\n\n\n

To measure whether or not a crop needs irrigation, it is best to measure the humidity of the subsoil at different depths, as we can do with Plantae sensors.<\/p>\n\n\n\n
