Garcinia kola is a multipurpose tree tropical forest species commonly found in West and Central Africa. The species is known as a miracle plant because of the of all its parts and the potentials to improve local income generation of the farmers. Nonetheless, limited information is available on the productivity of the species. This study investigate...

This article is a workshop report from PAGES Magazine (April 2025) on the first African Tree ring Network (ATRN) event held in Ethiopia and online. It highlights how dendrochronology is advancing climate resilience in Africa through tree-based data, collaboration, and capacity building.

The forestry sector faces several contests, including deforestation, climate change, and sustainable resource management. Innovative research is crucial to address these problems. This proceeding discusses the prospects and challenges of promoting innovative research in the forestry sector, including the potential for technological advancements suc...

Key message Radial growth and wood anatomical variables of G. kola have a direct relationship with climate. Rainforest regions are more suitable and could be recommended for stakeholders for conservation action plans. Abstract Tropical agroforestry species are characterized by irregular growth and fruiting pattern, this is because of seasonal diff...

Native multi-purpose tree species in West Africa, Cola nitida and Garcinia kola have the potential to advance agroforestry practices in the sub-region. There is limited information on the ecology of both species which are currently characterised by low yield (fruit). This study investigated the influences of vegetation type on the population struct...

The ability of Nigerian forest reserves to support livelihoods and provide ecosystem services such as improved primary healthcare, sustainable food production, income generation, and carbon sequestration to mitigate climate change impacts; is currently constrained by deforestation and other anthropogenic factors. Hence, a clear understanding of the...

The tropical rainforest ecosystem in Nigeria is very rich in species diversity and plays a significant role in conserving biodiversity resources and supporting livelihood. However, these ecosystems are characterized by inadequate information on the species diversity and biomass carbon accumulation This study investigated the above-ground biomass (A...

Sustainably managed watershed ecosystems play vital roles in ecological stability and contribute to livelihood sustenance. Unfortunately, most watershed ecosystems are threatened by anthropogenic activities such as arable crop cultivation, and infrastructural development. This study investigated the influence of land use on soil physicochemical pro...

Kolanut (Cola nitida) is a tropical multipurpose agroforestry tree species in Nigeria, the species receives little attention from studies geared towards assessing the impact of climate change on the services it provides. The study investigated farmers’ views on the impacts of current changes in climatic variables on the ecosystem services the speci...

Garcinia kola is an indigenous multipurpose tree species, with significant cultural value and medical benefits, commonly found in the tropical rain forest zone of West and Central Africa. The species has been reported to be over-used and are now classified as vulnerable species close to commercial extinction. Hence, requires immediate conservation...

Abstract Background Garcinia kola is an indigenous multipurpose tree species commonly found in the tropical rain forest zone of West and Central Africa. Providing economic, ecological, and socio-cultural benefits for people, they have potentials to improve the regional and local income generation to the farmers but the cultivation of the species is...

Dacroydes edulis (G. Don) HJ Lam is a multipurpose tree that provides a dual function of strengthening food security and carbon sequestration in rural environments. The aim of the study was to investigate the agroforestry potential of D. edulis in south western Nigeria and the objective was to access the phytosociology and determine the vegetative...

Garcinia kola and Cola nitida are important multipurpose economic tree species in Nigeria that have the potentials to contribute to the regional and local income generation of the rural people. The cultivation of both species is very much limited in Nigeria; they can contribute immensely to the livelihood of the rural dwellers. The study was carrie...

ABSTRACT The study investigated the influence of light intensities on the early growth performance of Mansonia altissima in other to create a favourable condition for good growth. Seedlings of M. altissima were monitored under five light intensities namely: under tree canopy (5%), 25%, 50%, 75% light intensities and control treatment was direct su...

Background and Purpose: The population of most of our economically indigenous tree species in Nigeria is declining. Human activities and agricultural practices have been the ultimate contributors to this decrease. In order to ameliorate the conflict between agriculture and forestry, agroforestry was introduced. However, most of the practiced agrofo...
