Above-Ground Biomass in Forest (tonnes/ha) 2018

Global Overview of Above-Ground Biomass in Forest (tonnes/ha) in 2018

In 2018, the country with the highest recorded Above-Ground Biomass in Forest (tonnes/ha) was Micronesia (Fed. States of) with an impressive value of 500.39 tonnes per hectare, while the global range of this metric spans from 0.00 to 500.39 tonnes/ha. The global average for this measure in 2018 was 126.75 tonnes/ha, with a median value of 112.76 tonnes/ha, illustrating significant disparities in biomass storage capabilities across different nations.

Geographic and Climatic Influences on Biomass Distribution

The distribution of above-ground biomass is heavily influenced by geographic and climatic conditions. Tropical countries, particularly in the Amazon Basin and Southeast Asia, tend to have higher biomass values due to their lush, dense forests. For instance, Guyana follows closely behind Micronesia with a biomass level of 498.96 tonnes/ha, attributed to its vast rainforests. Similarly, Palau at 416.21 tonnes/ha benefits from its tropical climate, which fosters robust vegetation growth.

In contrast, regions with arid climates or limited forested areas, such as the Middle East, show significantly lower biomass levels. For example, Gibraltar, Falkland Islands (Malvinas), and Monaco report a biomass of 0.00 tonnes/ha, indicating a stark absence of forest cover. This disparity highlights the critical role climate plays in determining biomass potential, as regions with adequate rainfall and suitable temperatures can support dense forest ecosystems.

Economic Factors and Policy Impacts on Biomass Levels

Economic activities and environmental policies significantly impact forest biomass levels. Countries like New Zealand and Bhutan, with biomass values of 295.02 and 269.32 tonnes/ha respectively, have implemented sustainable forestry practices and conservation policies that promote forest health and carbon storage. Bhutan, renowned for its commitment to environmental sustainability, emphasizes forest conservation, which directly contributes to its high biomass levels.

Conversely, countries experiencing rapid urbanization or deforestation often see declines in biomass. For example, Israel and Yemen, with biomass levels of 7.69 and 13.99 tonnes/ha respectively, face challenges due to land use changes that prioritize development over conservation. The contrast between these countries and those with higher biomass underscores the importance of prioritizing environmental policies that protect and restore forest ecosystems.

Year-Over-Year Changes: Movers and Shakers in Biomass

In 2018, the average change in above-ground biomass across the 200 countries with data was a modest 0.10 tonnes/ha, reflecting a slight increase of 0.1% year-over-year. However, some countries exhibited significant changes. Bulgaria led the increases with a rise of 3.73 tonnes/ha (2.2%), driven by efforts to enhance forest management and reforestation initiatives.

Saint Lucia also saw a notable increase of 3.32 tonnes/ha (1.2%), suggesting a positive trend in forest conservation. In contrast, countries like Solomon Islands experienced the largest decrease with a drop of -13.75 tonnes/ha (-11.4%), possibly due to logging and environmental degradation. Such fluctuations in biomass levels not only reflect ecological health but also indicate broader environmental trends and challenges faced by these nations.
