L’occupation des sols en 2020<\/h2>\n <\/div>\n <\/div>\n
\n \n \n
\n

En 2020, l\u2019occupation des sols de la Guin\u00e9e se caract\u00e9rise par la dominance des formations de savanes et de for\u00eats claires qui couvrent plus 70% du territoire. <\/p>\n

Les surfaces agricoles correspondent \u00e0 diff\u00e9rents syst\u00e8mes de cultures dont principalement : les cultures pluviales d\u2019abattis-br\u00fblis sur les interfluves, les cultures de bas-fonds et la riziculture inond\u00e9e en plaines c\u00f4ti\u00e8res. Ces\n surfaces de cultures vivri\u00e8res ne repr\u00e9sentent qu\u2019environ 4 millions d\u2019hectares soit 17% de la surface du pays. Les cultures p\u00e9rennes : caf\u00e9, cacao, palmiers \u00e0 huile, h\u00e9v\u00e9a repr\u00e9sentent 5% du territoire.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

Les changements d’occupation entre 2005 et 2020<\/h2>\n <\/div>\n <\/div>\n
\n \n \n
\n

D\u2019une mani\u00e8re g\u00e9n\u00e9rale les principaux changements d\u2019occupation des sols se traduisent par une perte importante des formations arbor\u00e9es et arbustives : en 15 ans les for\u00eats dense sont perdues 3% de leurs surfaces et les savanes 5%<\/p>\n

Ce recul des formations naturelles est d\u00fb \u00e0 une importante expansion urbaine ; un doublement des surfaces mini\u00e8res qui sont pass\u00e9es de 100 000 ha en 2005 \u00e0 plus de 25000 ha en 2020 et de l\u2019expansion agricole.<\/p>\n

Cette derni\u00e8re avoisine 1 Million d\u2019ha entre 2005 et 2020. Elle aurait tendance \u00e0 augmenter dans deux r\u00e9gions naturelles, la Haute Guin\u00e9e et la Guin\u00e9e Foresti\u00e8re, alors qu\u2019elle aurait tendance \u00e0 ralentir dans les deux autres r\u00e9gions\n naturelles, la Guin\u00e9e Maritime et la Moyenne Guin\u00e9e. Les surfaces agricoles se sont \u00e9tendues d\u2019environ 20% en 15 ans avec une nette acc\u00e9l\u00e9ration ces 5 derni\u00e8res ann\u00e9es. <\/p>\n

Les zones humides int\u00e9rieures et autres bas-fonds naturels et semi-naturels voient leurs surfaces se r\u00e9duire de 18% en 15 ans, probablement \u00e0 cause des extensions agricoles. Enfin les mangroves subissent \u00e9galement une pression\n mais qui semble faiblir ces 5 derni\u00e8res ann\u00e9es.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

La zonage agro-\u00e9cologique des terres<\/h2>\n <\/div>\n <\/div>\n
\n \n \n
\n

La surface globale des terres potentiellement aptes \u00e0 l\u2019agriculture en Guin\u00e9e s\u2019\u00e9l\u00e8ve en 2020 \u00e0 environ 15 millions d\u2019hectares (dont 9 millions avec des aptitudes moyennes \u00e0 fortes), soit 62 % du territoire national. 5.3 millions d\u2019hectares\n sont d\u00e9j\u00e0 cultiv\u00e9s selon des degr\u00e9s d\u2019intensit\u00e9 culturale tr\u00e8s divers. En plus des zones actuellement cultiv\u00e9es, pr\u00e8s de 10 millions d\u2019hectares seraient donc aptes \u00e0 une production agricole, en l\u2019absence de tout autre usage.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n

La vocation agricole des terres<\/h2>\n <\/div>\n <\/div>\n
\n \n \n
\n

Compte tenu des usages non agricoles actuels des terres : espaces miniers, zones urbaines, aires prot\u00e9g\u00e9es (parcs nationaux et for\u00eats class\u00e9es), 13.6 millions d\u2019hectares auraient une vocation agricole en 2020 (dont 8 millions avec\n des aptitudes moyennes \u00e0 bonnes), soit 55% du territoire national. 5.3 millions d\u2019hectares sont d\u00e9j\u00e0 cultiv\u00e9s. Ainsi la Guin\u00e9e dispose d\u2019un potentiel suppl\u00e9mentaire de terres \u00e0 vocation agricole d\u2019environ 8 millions d\u2019hectares.<\/p>\n

La r\u00e9gion naturelle de la Haute Guin\u00e9e repr\u00e9sente \u00e0 elle seule quasiment la moiti\u00e9 du potentiel agricole disponible de la R\u00e9publique de la Guin\u00e9e. Les r\u00e9gions de la Moyenne Guin\u00e9e et de la Guin\u00e9e Foresti\u00e8re disposent respectivement\n de 20% et la Guin\u00e9e Maritime environ 10%.<\/p>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n
