<p><strong><em>Surnomm\u00e9e, la \u00ab Suisse Africaine \u00bb, la Guin\u00e9e est un pays au relief accident\u00e9 dont l\u2019altitude varie de 0 m au niveau de la mer et culmine \u00e0 1752 m au Monts Nimba, au sud du pays, \u00e0 la fronti\u00e8re avec le Lib\u00e9ria et la C\u00f4te d\u2019Ivoire.&nbsp;Au c\u0153ur de l&rsquo;Afrique de l\u2019Ouest, c\u2019est un pays qui fait la synth\u00e8se des vastes ensembles tr\u00e8s diff\u00e9renci\u00e9s que l&rsquo;on retrouve dans cette r\u00e9gion (Beaujeu-Garnier, 1958).&nbsp;<\/em><\/strong><\/p>\n                    <p>D\u2019un point de vue g\u00e9omorphologique Boulvert (2003) divise la Guin\u00e9e en six grands ensembles morphologiques g\u00e9n\u00e9ralement regroup\u00e9s dans 4 grandes r\u00e9gions naturelles :<\/p>\n                    <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\u2022&nbsp;Les massifs et hauts plateaux du Fouta Djalon correspondant \u00e0 la Moyenne Guin\u00e9e ;\n                      <br>\n                    <\/p>\n                    <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\u2022 Les plaines c\u00f4ti\u00e8re, le plateau Bow\u00e9 et le plateau gr\u00e9seux de Kindia-T\u00e9lim\u00e9l\u00e9 formant la Guin\u00e9e Maritime (ou basse Guin\u00e9e) ;\n                      <br>\n                    <\/p>\n                    <p>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;\u2022&nbsp;Les

granitiques et de gneiss du Sud-Est guin\u00e9en formant la Guin\u00e9e Foresti\u00e8re.<\/p>\n                    <p>La g\u00e9ologie, la g\u00e9omorphologie et le climat ont favoris\u00e9 la formation d\u2019une grande diversit\u00e9 de type de sols, en termes de localisation, composition physico-chimique et structure, leur conf\u00e9rant une grande amplitude d\u2019aptitudes agronomiques.&nbsp;La\n                      g\u00e9omorphologie et les caract\u00e9ristiques physico-chimiques des sols influencent leur aptitude \u00e0 accueillir des cultures et les rendements agricoles \u00e0 attendre. Les fortes pentes limitent souvent les possibilit\u00e9s de mise en cultures\n                      annuelles (riz, sorgho, fonio, etc) car ces derni\u00e8res acc\u00e9l\u00e8rent alors l\u2019\u00e9rosion de la couche superficielle du sol et l\u2019appauvrissent. De la m\u00eame fa\u00e7on, les bas-fonds inondables sont difficilement cultivables sans un am\u00e9nagement\n                      hydraulique ad\u00e9quat.<\/p>\n                    <p>Les caract\u00e9ristiques des sols telles que leur texture, leur profondeur, leur r\u00e9serve utile tout comme leur composition chimique, sont autant de facteurs d\u00e9terminants pour d\u00e9finir leur fertilit\u00e9 intrins\u00e8que ; En Guin\u00e9e les sols dominants\n                      sont les sols ferrallitiques que l\u2019on trouve sur les plateaux et versants de Basse, moyenne et haute Guin\u00e9e. Ils ont des valeurs agronomiques assez bonnes : ils sont g\u00e9n\u00e9ralement profonds, peu acides. En revanche les sols lithiques\n                      sur cuirasse ont une faible valeur agronomique. Les sols de mangrove des plaines littorales ou les sols rajeunis par l\u2019\u00e9rosion dans les vall\u00e9es du dominant au sud de la Haute Guin\u00e9e et en Guin\u00e9e Foresti\u00e8re, constituent

     <p><strong><em>De par sa situation g\u00e9ographique entre 7\u00b030 et 12\u00b030 de latitude Nord, la Guin\u00e9e est partag\u00e9e en deux zones climatiques : i) une zone tropicale couvrant la majeure partie du territoire et ii) une zone sub\u00e9quatoriale au niveau du Sud Est. <\/em><\/strong><\/p>\n                    <p>Le r\u00e9gime pluviom\u00e9trique annuel est uni-modal avec une saison pluvieuse de mai \u00e0 octobre, suivie d\u2019une saison s\u00e8che de novembre \u00e0 avril. C\u2019est un pays tr\u00e8s pluvieux avec des moyennes annuelle variant de 1000 mm au nord \u00e0 plus de 3000\n                      mm sur le littoral, et cumulent partout en juillet et ao\u00fbt. Les temp\u00e9ratures sont \u00e9lev\u00e9es. Les moyennes annuelles varient de 19\u00b0C sur les sommets au Fouta Djallon et massifs de la Guin\u00e9e Foresti\u00e8re (Nimba et B\u00e9ro) et 30\u00b0C sur le\n                      littoral. L\u2019humidit\u00e9 relative moyenne annuelle de l\u2019air est sup\u00e9rieure \u00e0 60 pour cent, avec un minimum de 29 pour cent en moyenne Guin\u00e9e (Lab\u00e9) et un maximum de 98 pour cent en basse Guin\u00e9e (Conakry). L\u2019\u00e9vapotranspiration moyenne\n                      annuelle va de 1 500 mm \u00e0 2500 mm.&nbsp;Les pr\u00e9cipitations et les temp\u00e9ratures sont influenc\u00e9es par deux vents dominants, l\u2019Harmattan, vent sec venant du nord qui souffle de d\u00e9cembre \u00e0 f\u00e9vrier et de la mousson, vent charg\u00e9 d\u2019humidit\u00e9\n                      venant de l\u2019Oc\u00e9an Atlantique. Les variables climatiques influen\u00e7ant la production agricole sont nombreuses : pluviom\u00e9trie moyenne, nombre de jours de pluies, nombre de jours de s\u00e9cheresse, nombre de jours de gel, temp\u00e9ratures extr\u00eames,\n                      cumul de temp\u00e9ratures, etc. Leur influence d\u00e9pend des besoins de chaque culture et des sols. Ainsi les besoins climatiques des c\u00e9r\u00e9ales (Mais, Sorgho, Riz) ne sont pas les m\u00eames que ceux des tubercules (Manioc, Igname) ou des plantes\n                      p\u00e9rennes (Palmier \u00e0 huile, Anacardier).<\/p>\n                    <p>N\u00e9anmoins, lorsque l\u2019on ne vise pas une plante particuli\u00e8re un indicateur synth\u00e9tique permet d\u2019approcher les conditions g\u00e9n\u00e9rales climatiques favorables \u00e0 la croissance des cultures et \u00e0 leur production : la longueur de la p\u00e9riode\n                      de croissance (LPC). Elle se d\u00e9finit comme la p\u00e9riode de l&rsquo;ann\u00e9e o\u00f9 sont r\u00e9unies les conditions de temp\u00e9rature et d&rsquo;humidit\u00e9 ad\u00e9quates pour la production agricole. La FAO la d\u00e9finit comme la p\u00e9riode de l&rsquo;ann\u00e9e durant laquelle dominent\n                      les temp\u00e9ratures permettant la croissance des plantes (T moyenne &gt;= 5\u00b0C) et durant laquelle la somme pr\u00e9cipitation + humidit\u00e9 emmagasin\u00e9e dans le sol d\u00e9passe la moiti\u00e9 de l&rsquo;\u00e9vapotranspiration potentielle (ETP) (FAO, 1997). Dans\n                      la pr\u00e9sente \u00e9tude, nous l\u2019avons d\u00e9finie comme le nombre de mois o\u00f9 la temp\u00e9rature moyenne mensuelle (TMOYm) est &gt;= 5 \u00b0C, et o\u00f9 le bilan hydrique mensuel (BHm) est positif. Ce dernier se calcule mois apr\u00e8s mois en tenant compte\n                      de la R\u00e9serve Hydrique du sol (RHm), de la pluviom\u00e9trie mensuelle (Pm) et de l\u2019\u00e9vapotranspiration

<p><strong><em>Globalement les activit\u00e9s humaines et notamment les extensions urbaines, mini\u00e8res, et agricoles se sont consid\u00e9rablement accrues ces 5 derni\u00e8res ann\u00e9es. <\/em><\/strong><\/p>\n                    <p>La vitesse de l\u2019expansion urbaine a doubl\u00e9, passant de 1% par an entre 2005 et 2015 \u00e0 2% par an de 2015 \u00e0 2020. Les surfaces des carri\u00e8res, des extractions mini\u00e8res et des autres chantiers ont doubl\u00e9 en 5 ans principalement dans les\n                      r\u00e9gions de Guin\u00e9e Maritime et Haute Guin\u00e9e. Avec des surfaces estim\u00e9es \u00e0 10 000 ha dans les ann\u00e9es 2005 et \u00e0 13 000 ha en 2015, ces derni\u00e8res d\u00e9passent aujourd\u2019hui 25 000 ha. L\u2019expansion agricole avoisine 1 Million d\u2019ha entre 2005\n                      et 2020. Cette extension a 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 naturelles, la Guin\u00e9e Maritime et la Moyenne\n                      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.&nbsp;<\/p>\n                    <p>M\u00eame si la for\u00eat ne peut pas par endroit s\u2019\u00e9tendre, en particulier dans les zones prot\u00e9g\u00e9es, les extensions agricoles, urbaines et mini\u00e8res ont pour cons\u00e9quence une grande pression et d\u00e9gradation sur les formations arbor\u00e9es et arbustives\n                      avec respectivement une perte de 3% des for\u00eats denses et claires en 15 ans et de pr\u00e8s de 5% des savanes arbor\u00e9es. Les zones humides int\u00e9rieures et autres bas-fonds naturels et semi-naturels voient leurs surfaces se r\u00e9duire de 18%\n                      en 15 ans, probablement \u00e0 cause des extensions agricoles.&nbsp;Enfin les mangroves subissent toujours une pression mais qui semble faiblir ces 5 derni\u00e8res ann\u00e9es avec une perte de 1.8% de leur surface entre 2005 et 2015 et une perte\n
