            <gco:CharacterString>Cette couche de donn&#233;es INSPIRE reprend les teneurs en Carbone Organique Total dans les sols agricoles du territoire wallon pour la p&#233;riode 1949-1972.

Cette donn&#233;e conforme INSPIRE est issue de la donn&#233;e source CARBIOSOL - Teneurs pr&#233;dites en Carbone organique total - p&#233;riode 1949-1972.

La qualit&#233; d&#8217;un sol peut &#234;tre &#233;valu&#233;e gr&#226;ce &#224; l&#8217;&#233;tude de divers param&#232;tres physiques, chimiques ou biologiques. Parmi ces param&#232;tres, le carbone organique des sols, qui constitue plus de 50% de la masse de la mati&#232;re organique du sol, est g&#233;n&#233;ralement consid&#233;r&#233; comme l'indicateur principal de la qualit&#233; des sols, &#224; la fois pour ses fonctions agricoles et environnementales.

La pr&#233;sente couche de donn&#233;es constitue la cartographie des teneurs en carbone organique total (COT) historiques pour les sols sous cultures et prairies permanentes en R&#233;gion wallonne. La p&#233;riode couverte par cette cartographie s'&#233;tend de f&#233;vrier 1949 &#224; juillet 1972. La couche a &#233;t&#233; cr&#233;&#233;e par m&#233;thode de mod&#233;lisation spatiale d&#233;velopp&#233;e par l'UCL dans le cadre de la convention CARBIOSOL.

Pour plus de d&#233;tails sur la constitution des couches cartographiques g&#233;n&#233;r&#233;es dans le cadre du projet CARBIOSOL, veuillez-vous r&#233;f&#233;rer &#224; la fiche de m&#233;tadonn&#233;es documentant la s&#233;rie de couches de donn&#233;es.

En chaque pixel, la teneur en carbone organique total (COT) est exprim&#233;e en gramme de carbone par kilogramme de terre fine s&#232;che (gC/kg). Le r&#233;sultat en sortie du mod&#232;le est une couche raster des teneurs en COT &#224; 90 m&#232;tres de r&#233;solution et spatialement continue sur le territoire agricole wallon.

Les teneurs moyennes en COT pour les sols sous cultures et prairies sur la p&#233;riode 1949-1972 &#233;taient de 1.62 gC/kg et 3.26 gC/kg. Sur cette p&#233;riode, 9% des superficies agricoles pr&#233;sentaient des teneurs en COT &lt; 1.15 %C et 60% pr&#233;sentaient des teneurs &lt; 1.5 gC kg-1. En de&#231;&#224; de 1.15 gC/kg, le sol est d&#233;structur&#233;.

Les teneurs en COT des sols pour les deux occupations de sols tendent &#224; augmenter du nord-ouest au sud-est, de la r&#233;gion sablo-limoneuse &#224; la r&#233;gion ardennaise, et rebaisser en r&#233;gion Jurassique. Cette tendance refl&#232;te les variations de relief et de sols contr&#244;lant &#233;galement l&#8217;&#233;volution de l&#8217;occupation des sols (de cultures intensives &#224; prairies permanentes extensives dominantes), mais &#233;galement les variations climatiques.</gco:CharacterString>

                <gco:CharacterString>1. Cadre de conception de la couche de donn&#233;es

La pr&#233;sente couche de donn&#233;es repose sur une m&#233;thodologie de cartographie du Carbone Organique Total (COT) mise au point &#224; l'&#233;chelle de la Wallonie dans le cadre du projet CARBIOSOL I et adapt&#233;e dans le cadre de CARBIOSOL II. Cette m&#233;thode a &#233;t&#233; d&#233;velopp&#233;e par l'UCLouvain, l'ULi&#232;ge et la DGARNE (SPW-DGO3).

2. Donn&#233;es de r&#233;f&#233;rence

Pour la p&#233;riode 2015-2019, les donn&#233;es d&#8217;entr&#233;e pour les cultures et prairies correspondent aux teneurs en COT mesur&#233;es par le r&#233;seau de laboratoires REQUASUD dans le cadre des analyses de terres effectu&#233;es &#224; la demande des agriculteurs (Ref : Requasud - Licence 109/2016). Seules les donn&#233;es g&#233;or&#233;f&#233;renc&#233;es ont &#233;t&#233; prises en compte, car elles seules peuvent &#234;tre utiles &#224; la m&#233;thode de mod&#233;lisation choisie. Le sol de chaque parcelle est pr&#233;lev&#233; selon un &#233;chantillonnage composite effectu&#233; sur l&#8217;horizon de surface sur l&#8217;ensemble de la parcelle diagnostiqu&#233;e/test&#233;e. Pour plus de d&#233;tails sur la base de donn&#233;es Sols de Requasud, veuillez vous reporter &#224; la fiche correspondante. 

Les co-variables significatives pour expliquer la variance des teneurs en COT pour chaque occupation de sols &#233;taient :
- pour les cultures : la teneur en argiles et limons fins, l'altitude, le C-factor (indicateur de couverture v&#233;g&#233;tale), la longueur de flux, la teneur en limons et les donn&#233;es climatiques (2001-2006) ;
- pour les prairies : la teneur en argiles et limons fins, l'altitude, les apports de C par fumures et lisiers calcul&#233;s par communes, la longueur de flux et les donn&#233;es climatiques (2001-2006) ;

3. Logiciels et m&#233;thode

La m&#233;thodologie et les outils utilis&#233;s dans le cadre de la constitution de la pr&#233;sente couche de donn&#233;es sont similaires pour toutes les variables relatives au carbone organique des sols &#233;tudi&#233;es dans le cadre de la convention CARBIOSOL. Veuillez-vous r&#233;f&#233;rer &#224; la fiche de m&#233;tadonn&#233;es documentant la s&#233;rie de couches de donn&#233;es - part.
