    Abstract: The integration of trees on farmlands has recently received attention due to their contribution to livelihoods improvement and climate change mitigation. They provide ecosystem services (ESs) like climate change mitigation, improvement of soil fertility, provision of timber and fuelwood among others. The choice of trees to plant depends on the role...

    Abstract: The extent of any forest determines its capacity to supply goods and services which are indispensable for man’s continued existence. However, increasing population of humans subjects forest under pressure to meet basic needs of man thereby modifying its extent mostly through deforestation and forest degradation. It therefore became necessary to inv... Show More

    Abstract: The Ivorian economy is essentially based on agriculture, especially the coffee-cocoa duo. The country experienced growth in the 1970s, perceived by specialists as the "Ivorian miracle". But this euphoria turned into "an economic mirage", because of certain factors including the aging of plants, the slowdown in cocoa production. Faced with this situ... Show More

    Abstract: A forest is an object so complex that it can never be known in all its details. But it is possible to get a "simplified picture" of the forest functioning, i.e. it is possible to build a "model". For this purpose, a forest may be considered as a landscape, the elements of which are the model basis; each element of a forested landscape is then the f... Show More

    Abstract: To scientifically solve the taxonomical confusion of Yulania sprengeri (Pamp.) D. L. Fu in the world, the chloroplast genomic sequences of four confusable species were assembled and compared with the other species of Yulania Spach by means of the typical algorithm. The results indicated that the evolutionary system of Yulania Spach includes four na... Show More
