Formal causal connectors (debido a, a causa de)

Official municipal announcements often use formal causal connectors to explain decisions, such as water rationing during a severe drought.

Debido a (Due to)

Use debido a before a noun to mean "due to" or "because of".

Due to the drought, there will not be enough water supply.
Debido a la sequía, no habrá suficiente suministro de agua.

Remember that the preposition a and the masculine article el contract to form al.

The municipal announcement indicates that they will cut the supply due to the heat.
El aviso municipal indica que cortarán el suministro debido al calor.

To follow the connector with a conjugated verb instead of a noun, add que to form debido a que (because / due to the fact that).

We will have to restrict consumption because it is not raining.
Tendremos que restringir el consumo debido a que no llueve.
Because the storm destroyed the supply, the hospital will not have water.
Debido a que la tormenta destruyó el suministro, el hospital no tendrá agua.

A causa de (Because of)

Use a causa de before a noun to mean "because of" or "as a result of". It is very similar to debido a.

Because of the shortage, the municipal government will close the park.
A causa de la escasez, el gobierno municipal cerrará el parque.
Because of this problem, the rationing will affect everyone.
A causa de este problema, el racionamiento afectará a todos.
