Projet de design graphique tourné vers l’édition.

Le but était de promouvoir la Zambie et sa culture via un petit livret informatif. Je voulais qu’on puisse avoir quelques proverbes et en même temps des informations en rapport avec le thèmes des poèmes!

Gradual increase in atmospheric temperature due to elevated levels of greenhouse gases has become a global agenda. Of these gases, carbon dioxide is the most predominant accounting for more than half of the atmospheric warming. Conveniently, forests and woodlands are important sinks of carbon through sequestration which involves carbon dioxide capture and storage. Miombo woodlands are the most widespread savanna vegetation in the Sub-Saharan Africa, and like other vegetation they are likely to have a marked degree of carbon sequestration. However, these ecosystems are normally threatened by many disturbances, including outbreaks of uncontrolled and destructive fires. Yet, it has been reported that wildfires have both positive and negative influence on carbon sequestration in forests and woodlands. The aim of the present study was to determine tree carbon in Ilunde forest after consecutive exposure to frequent fires for 10 years. A fire suppressed forest of Kitwe was used as a control. Fire frequency of Ilunde forest was obtained from published Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery from the year 2001 to 2012. Tree carbon stock was estimated using biomass allometric models so far developed for miombo woodlands.The level of difference in carbon density between the two forests was determined using t-test. Tree carbon stock was significantly high in Kitwe forest than in Ilunde (P < 0.05). The effects of wildfires are variable depending on the nature of ecosystems and the existing circumstances. Since fire is crucial in miombo woodlands, then prescribed burning could be prioritized to sustain sinks of carbon.

COMPARISON OF VARIED FOREST INVENTORY METHODS AND OPERATING PROCEDURES FOR ESTIMATING ABOVE-GROUND BIOMASS IN MALAWI’S MIOMBO WOODLANDS | Journal of Global Ecology and Environment

The methodologies and standard operating procedures (SOPs) for assessing above-ground biomass (AGB) and carbon in Malawi's important REDD+ Miombo Forest Reserves were evaluated in this study. The following methodologies and SOPs were investigated using the Analysis of Variance statistical technique: I allometry, (ii) sample plot arrangement, and (iii) dendrometric measures. The allometric equations parameter substantially (P0.001) influenced AGB estimates and was the most significant contributor (97.95%) to the overall variance. Malawi has the highest AGB estimate (113.081.56 t/ha) according to its particular allometry. The Pan-Tropical/generalized allometric models, on the other hand, significantly underestimated AGB by 16.7% to 67.9%. Furthermore, the data show that different sample plot sizes had a substantial (P0.001) impact on AGB estimations. The plot size parameter, on the other hand, only accounted for 1.65% of the overall variance. In comparison to the 17.84m radius plot (66.121.61), the 20m radius plot has the greatest AGB (75.310.77). This means that the 17.84m radius plot size underestimated the AGB by 12.2 percent. However, despite the former yielding higher estimates of AGB (74.650.93 t/ha) than the latter (72.530.98 t/ha), results on dendrometric measurements revealed no significant (P>0.05) differences in AGB estimates between the use of diameter tape (D-tape) and calliper in measuring dbh of individual trees. This shows that using a calliper to measure dbh only overestimated AGB t/ha by 2.8 percent compared to using D-tape. As a result, the study suggests using local allometry and using a circular sample approach. Please see the link :- https://www.ikprress.org/index.php/JOGEE/article/view/7675

Abstract

Gradual increase in atmospheric temperature due to elevated levels of greenhouse gases has become a global agenda. Of these gases, carbon dioxide is the most predominant accounting for more than half of the atmospheric warming. Conveniently, forests and woodlands are important sinks of carbon through sequestration which involves carbon dioxide capture and storage. Miombo woodlands are the most widespread savanna vegetation in the Sub-Saharan Africa, and like other vegetation they are likely to have a marked degree of carbon sequestration. However, these ecosystems are normally threatened by many disturbances, including outbreaks of uncontrolled and destructive fires. Yet, it has been reported that wildfires have both positive and negative influence on carbon sequestration in forests and woodlands. The aim of the present study was to determine tree carbon in Ilunde forest after consecutive exposure to frequent fires for 10 years. A fire suppressed forest of Kitwe was used as a control. Fire frequency of Ilunde forest was obtained from published Moderate Resolution Imaging Spectroradiometer (MODIS) satellite imagery from the year 2001 to 2012. Tree carbon stock was estimated using biomass allometric models so far developed for miombo woodlands.The level of difference in carbon density between the two forests was determined using t-test. Tree carbon stock was significantly high in Kitwe forest than in Ilunde (P < 0.05). The effects of wildfires are variable depending on the nature of ecosystems and the existing circumstances. Since fire is crucial in miombo woodlands, then prescribed burning could be prioritized to sustain sinks of carbon.
