The main consequences are declining of crop yields, lack of farming land and loss natural pastures. Rehabilitation actions undertaken by indice de martonne communities surveyed include earth dikes, tillage including cart or hoe ploughing, application of organic matter, integrating farming techniques such as fallowing, association and rotation of crop, and lastly, parking of animals on plots to be rehabilitated.

  • L'indice d'aridité

Populations indice de martonne in their majority perceive in six months to three years signs of real change on planning plots. The index depends linearly on the annual temperature amplitude A difference of monthly mean temperature of warmest and coldest month.

However, A indice de martonne only depends on the strength of the influence of the ocean but also on the annual cycle of incoming solar radiation. Since the amplitude of the annual cycle of incoming solar radiation depends on latitude, with a maximum in the polar regions, the inverse of the sine of the latitude gets in as well.

The definition in the indice de martonne of Gorczynski is This original equation comes with some drawbacks. Since the sine approaches zero as the latitude approaches the equator, the values close to the equator tend to infinity.

At the equator the definition breaks down. Therefore, in this study we examined variations in the leaf morphological and stomatal characteristics of sixteen paper birch populations indice de martonne across Canada and grown in a common garden.

Significant genotypic differences were found in the leaf characteristics measured among the birch populations. Thus, we expected that the observed leaf variations may be partly explained as natural diversity in the birch indice de martonne to differences in environment of origin.
