Above-Ground Biomass in Forest (tonnes/ha) 2017

Overview of Above-Ground Biomass in Forest (tonnes/ha) in 2017

In 2017, the country with the highest Above-Ground Biomass in Forest (tonnes/ha) was Micronesia (Fed. States of) at 500.39 tonnes/ha, while the global range of values spanned from 0.00 to 500.39 tonnes/ha. The average Above-Ground Biomass across the 200 countries with available data was 126.65 tonnes/ha, with a median value of 112.58 tonnes/ha.

Geographic Influences on Biomass Density

The distribution of above-ground biomass is heavily influenced by geographic and climatic factors. Tropical regions generally exhibit higher biomass densities due to favorable growing conditions. For instance, Guyana reported 498.96 tonnes/ha, closely following Micronesia, while other tropical nations like Palau and French Guiana also showcased significant biomass levels at 416.21 and 365 tonnes/ha, respectively. In contrast, arid regions tend to have much lower biomass figures; for example, Qatar and Monaco both recorded 0.00 tonnes/ha, highlighting the stark contrast in biomass potential between these landscapes.

Economic Factors Impacting Above-Ground Biomass

Economic activities significantly shape forest management practices and consequently affect above-ground biomass levels. Countries with strong conservation policies and sustainable forestry practices tend to maintain higher biomass levels. For example, New Zealand, with a biomass of 294.49 tonnes/ha, has invested considerably in sustainable forestry management, which contrasts sharply with nations like Saudi Arabia, which reported only 26.61 tonnes/ha. This discrepancy can be attributed to the differing economic priorities; while New Zealand emphasizes conservation, Saudi Arabia's economy is heavily reliant on oil, leading to less focus on forest preservation.

Year-over-Year Changes and Notable Movements

The year-over-year changes in above-ground biomass demonstrate a mixed landscape of progress and decline. The average change across the dataset was a modest increase of 0.07 tonnes/ha. However, some countries experienced significant fluctuations. For instance, Bulgaria saw an increase of 3.89 tonnes/ha, representing a 2.4% rise, likely due to improved forest management practices and reforestation efforts. Conversely, countries like Zimbabwe and the Solomon Islands reported declines of 10.11 and 13.07 tonnes/ha, respectively, which can be attributed to deforestation and land degradation. Such losses not only reduce carbon storage capacity but also threaten biodiversity.

Conclusion: The Significance of Biomass Measurements

Understanding the above-ground biomass in forests is crucial for assessing carbon storage and the overall health of forest ecosystems. The substantial differences observed in biomass levels across countries underscore the importance of tailored environmental policies and sustainable practices. Nations with rich biodiversity and effective conservation strategies, such as Guyana and Micronesia, illustrate the potential for high carbon sequestration, while others with minimal biomass reflect urgent needs for reform in land management and environmental protection. As global awareness of climate change intensifies, the significance of these metrics will only grow, influencing international policy and conservation efforts.
