ArticleTree-biomass-carbon estimation in the coastal afforestation sites of Chittagong, Bangladesh
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Global climate is changing relentlessly due to anthropogenic greenhouse gas emissions into the atmosphere. Its impacts are globally visible now. Bangladesh is the worst-affected country in the world due to this climate change. Coastal afforestation, among several forestry options, is critical to climate change mitigation and adaptation. This study estimated the tree biomass growth and its carbon in the Kattoli and Parki beach under the Chittagong coastal forest division. The study estimated that the total biomass density of Acacia auriculiformis, Acacia nilotica, Avicennia officinalis, Casuarina equisetifolia, Samanea saman, Sonneratia apetala and Terminalia arjuna were 131.57±6.77, 116.96±6.41, 350.64±7.99, 296.47±9.46, 119.27±7.45, 154.86±4.78 and 117.11±9.68 tha-1, respectively, with the mean annual increment of 65.79±3.38, 58.48±3.20, 15.25±0.35, 33.15±1.60, 59.63±3.73, 6.45±0.11 and 58.55±4.84 tha-1 yr-1, respectively. Furthermore, the total biomass-carbon of each species was also estimated, which were 65.79±3.38, 58.48±3.2, 175.32±3.10, 148.23±4.73, 59.63±3.73, 77.43±2.39 and 58.55±4.84 tCha-1 for the respective species, respectively, with the mean annual increment of 32.89±1.69, 29.24±1.60, 7.62±0.17, 16.57±0.80, 29.82±1.86, 3.23±0.10, 29.28±2.42 tCha-1 yr-1, respectively. All the findings of the study indicate that afforestation with both mangrove and non-mangrove species along with the coastal belts in Chittagong has the potential to mitigate climate change. The results can be useful for climate change mitigation practitioners, researchers, and policymakers on a native and broad scale.

ArticleIncreasing land cover by promoting agroforestry-based tree planting to sustain community livelihood under various social forestry schemes in Indonesia
XV World Forestry Congress, 2-6 May 2022

No results found.The high challenges and expectations in the management of Indonesian Tropical Forests to achieve the community welfare, forest sustainability and sustainable development goals, demands proper management in optimizing the use of forest resources to meet the high dependence of community needs on the forest. The pressure on forests is reflected in the deforestation that occurs as an indication of the various dependencies of the community on forests to meet their daily needs. In this regard, Agroforestry is a potential silvicultural recipe as a solution to restore degraded land and forest that can gain balance ecological, economic and social benefits. This paper aims to provide information on plant growth performance and survival rate in the establishment of agroforestry plot for a total 34 hectares in three schemes of Social Forestry in Indonesia, namely Paru Village Forest (VF)–West Sumatra, Cempaka Forestry Partnership (FP)–Lampung, Tuar Tana Community Forestry (CF)– East Nusa Tenggara, in collaboration between Forestry and Environment Research, Development and Innovation Agency with the Asian Forest Cooperation Organization (AFoCO). It was conducted by planting 26 plant sp Intensive Artificial Regeneration with planting distance of 8x8 m and 5x5 m depend on plant species. The collected data covered for survival rate and height measurement. Growth Percentage was observed at ages 1, 6, 12 and 18 months after plan participation which looks high in maintaining their crops while survival rate in Tuar Tana CF was low enough only 43,2% due to the drough in this semi-arid region which affect the plant growth, eventhough the farmers have high effort in maintaining their crops.

DocumentMultiple uses of forest biomass as nature-based solution in order to increase the share of green and renewable energy at the energy matrix of several industries

No results found.The Brazilian Tree Industry (Ibá) is the association responsible for institutionally representing the planted tree production chain with its main stakeholders. Ibá represents 50 companies and 9 state entities for products originating from planted trees, most notably wood panels, laminate flooring, pulp, paper, charcoal steel industry and biomass, as well as independent producers and financial investors which together contribute with 7% of Brazil’s industrial Gross Domestic Product.
The sector holds 9 million hectares of planted trees and 5.9 million hectares for conservation. The total forest area removes carbon from the atmosphere and stores the carbon into six carbon pools with the potential of storing 4,48 bi TCO2e.
Forest biomass also plays an important role of avoiding carbon emission to the atmosphere when used in industry. By investing in circular bioeconomy this industry has transformed a residue from pulp mills into a source of renewable bioenergy - the black liquor, which represents 69% of the total energy needed by the sector. Adding 20% of forest biomass chip and shavings, the energy matrix of this sector reaches 89% of renewability. Additionally, Brazil is the global leader of charcoal production (12%). 1.8 ton CO2eq is avoided for each ton of pig iron. Such contribution has gained attention from ENDP and GEF, both organizations support an initiative called Sustainable Steelmaking Project - unique from Brazil and that has significant importance in social, environmental and economic aspects. The charcoal industry may also be able to increase energy production by using the gases from pyrolysis through a cogeneration process. Looking at the future, the sector has been investing in innovation to, in the mid-long term, offer bio-oils and 2nd generation ethanol which may contribute mostly for transportation industry – road and aviation. The forest carbon has an innate role at circular economy and provides renewable services and products, especially bioenergy. Keywords: Climate change, Value chain, Innovation ID: 3487071
