Role of The Forest-Savanna Transition Zones in Mitigating Climate Change at Lamto Scientific Reserve, Côte d’Ivoire

/in /by

In the context of global climate change, forests play a crucial role as carbon sinks, contributing to regulating greenhouse gases and stabilising the climate. This study evaluates the role of forest-savanna transition zones in mitigating climate change at Lamto Scientific Reserve, Côte d’Ivoire, by assessing their carbon sequestration capacity and economic value. The study employed a combination of field surveys, remote sensing and statistical analysis to gather and analyse the data. The floristic inventory recorded 4,018 individuals, distributed among 142 species, 92 genus, and 37 families.  The stem density ranges from 510 stems/ha (shrub savanna) to 758 stems/ha (moist semi-deciduous forest), with a basal area varying from 5.65 m²/ha (open forest) to 11.79 m²/ha (gallery forest). The vegetation structure, characterised by a “bell-shaped” vertical stratification and an “inverted J” horizontal distribution, reflects active regeneration. In terms of biomass and carbon sequestration, the gallery forest dominates with 287.37 ± 201.68 t/ha of biomass, 143.69 ± 100.84 tC/ha of carbon, and an exceptional capacity to sequester 526.856 tCO₂/ha, accounting for 57.6% of the total carbon sequestered. Its economic value, supported by mechanisms such as REDD+ High, reaches 13,171 EUR/ha (8,639,880 FCFA). In contrast, the shrub savanna, with a biomass of 9.38 ± 8.41 t/ha and limited sequestration of 17.203 tCO₂/ha, offers a maximum value of 430 EUR/ha (282,111 FCFA). The results highlight the key role of the gallery forest as the primary carbon sink and the economic potential of Lamto’s ecosystems. They underscore sustainable management’s importance in maximising climate regulation, preserving biodiversity, and enhancing ecological resilience.

Algae’s Promise to Sequester Carbon Sheds New Insight on Changing Climate

/in /by

The addition of more greenhouse gases (GHG) to the earth’s atmosphere, which accounts for more than half of the planet’s warming potential, has resulted in changes in long-term average weather conditions, or climate change. In order to counter the increased concentration of carbon dioxide in the atmosphere, carbon sequestration is a newly developed strategy. Contrary to carbon emission reduction measures, carbon sequestration has a strong potential to lower carbon dioxide levels or mask carbon dioxide emission if the gas is trapped from several stationary sources and used effectively to produce chemical and energy. The implementation of carbon regulations has spread widely.

The cost of air pollution is credited with a monetary value. Due to this, investments in the growth of microalgae for carbon sequestration have received attention from all around the world. With these systems, existing carbon mitigation strategies are shown to be a viable and promising alternative. In general, the microorganism groups that make up microalgae are extremely diverse and quick-growing, and they are very skilled in photoautotrophic, heterotrophic, and mixotrophic settings. With a unit carbon dioxide fixation capacity 10–50 times greater than terrestrial plants, these microalgae can be grown on non-fertile land. Describe in detail the most recent advancement in the effective use of microalgae for carbon dioxide in this article review.
