This work establishes the relationship between bioclimatology and agronomy. Bioclimatic
indices are obtained for several areas under olive cultivation and correlated with olive yields. Due
to the effect of climate change on cultivation and the high economic losses it produces, we propose
a sustainable development model for the territorial classification of crops based on bioclimatic
knowledge. Bioclimatic diagrams are prepared to provide information on water stress in crops so
that irrigation can be carried out at the most effective time, a measure that has been shown to lead
to water and energy savings for growers. In addition to this development model, we propose the
application of non-aggressive cultivation techniques such as the use of living plant cover to ensure
the protection of the soil and avoid losses due to climate irregularities. Studies conducted up to
the present on applied bioclimatology have yielded promising results in the fields of farming and
forestry. The maps and bioclimatic indices of Professor Rivas-Martínez, Ic, Io and It/Itc, are essential
for bioclimatic classification. The agricultural development model with a bioclimatic basis ensures
economic savings for growers and minimizes the environmental impact of cultivation. In the case of
olive cultivation we detected that in 2005 all the cultivated areas that were not in their thermoclimatic
optimum were damaged by frost. The widespread cultivation of olive groves in the Mediterranean
basin, and mainly in the south of Spain, is reason enough to establish a relationship between its
production and its bioclimatic environment. The ombroclimatic study in certain localities under olive
cultivation shows that areas with Io <2.5 are unproductive (Jodar, Tabernas), and that their low Io
value needs to be supplemented with irrigation water. This means extracting water from aquifers
for agricultural use, when the current climate irregularities do not allow the excessive use of subsoil
water. For the time being the only way of mitigating this situation is with sustainable development,
which requires a bioclimatic understanding of the territory; and the use of appropriate cultivation
techniques, including herbaceous plant covers. In this last case a knowledge of the plant associations
in the phytosociological class Stellarietea mediae constitutes the basis for establishing either natural or
sown vegetation cover
