Geography

"Using the right word, the right idea, the right concept, with the most commonly accepted definition, or even better, with the best accepted and understood definition, can sometimes be a feat...”

Patrick Triplet

> With this quote, we wish to pay tribute to the colosal work of this biologist, and doctor of ecology whose great oeuvre, Dictionnaire encyclopédique de la diversité biologique et de la conservation de la nature (The Encyclopaedic Dictionary of Biological Diversity and Nature Conservation) ─ compiled over the course of more than ten years ─ is the basis of many of the definitions found in this glossary. Indeed, it is by using a language with precise words and clearly defined concepts that everyone and anyone can approach and understand fields of study that may not necessarily be within their own expertise.

This glossary of over 6,000 definitions, written in French with corresponding English translations, is here to help you. It covers the complementary fields of Geography, Ecology, and Economics, without forgetting a small detour into the world of Finance, which of course regulates a large part of our existence.

Travelling from one definition to another, this glossary invites you to explore the rich world of conservation and to understand its mechanisms and challenges.

We wish you all : "Happy reading and a safe journey through our world".

Eau douce

Eau de faible teneur en sels la rendant apte au captage destiné à diverses utilisations, en particulier à l'irrigation et à l'alimentation humaine.
Les limites des teneurs en sels entre eau douce, eau saumâtre et eau salée (= de mer) ne sont pas fixées avec rigueur et peuvent varier suivant les législations. Cependant, les eaux marines ont des teneurs en sels allant en général de 10 à 38 grammes par litre suivant les arrivées d'eau douce par les fleuves, parfois beaucoup plus (exemple : mer Morte jusqu'à 260 grammes par litre).
Une eau est douce, au sens de la consommation humaine, si elle contient moins de 0,5 gramme par litre.
