ArticleConservation of green blue carbon ecosystem: Local perceptions and awareness on mangrove forest
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Management of blue carbon ecosystems including mangrove and seagrass beds is necessary to reduce the global carbon emissions and mitigate the impacts of climate change, in addition to the managements of terrestrial forest ecosystem. The scheme of the REDD+, which is Reducing Emissions from Deforestation and forest Degradation, plus the sustainable management of forests, and the conservation and enhancement of forest carbon stocks, has been used for the managements of different types of forests and related ecosystems. The concepts of REDD+ can be applied for the blue carbon ecosystems. In recent academic literatures, the discussion of the application of REDD+ is increasing, considering the characteristics of the management of blue carbon ecosystems. The management of blue carbon ecosystems need the various stakeholders’ collaboration, because they are in the border of different ecosystems including terrestrial and coastal ones, where different types of livelihoods and industries co-exist. To identify the status of discussions of REDD+ for blue carbon ecosystems, literature review on REDD+ and blue carbon ecosystem management was conducted by using quantitative text mining approaches. Regarding the local perceptions and awareness on mangrove forest, a case study in the Philippines was conducted. In concrete terms, household surveys to the locals in Eastern Samar were implemented to identify their perceptions and awareness. The analysis result can contribute to science-policy interface by providing the following information; resource utilization, level of awareness on ecosystem services and existing management plans, and perceptions on natural and anthropogenic threats. It reveals that social demography and level of awareness of the locals are factors which influence status of utilization of mangrove ecosystem services. Those result can be used as an evidence of policy making and facilitate the application of conservation schemes considering the local context of the study site.

ArticleVolume yield, tree species diversity and carbon storage of sacred groves in Southwestern Nigeria
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Recently, the role of sacred groves in biodiversity conservation and provision of ecosystem goods and services has been a subjected to scientific investigation. In this study, data were collected from four sacred groves (Osun‐Osogbo, Igbo‐Olodumare, Idanre Hills and Ogun‐Onire) in southwestern, Nigeria to investigate their volume yield, tree species diversity, biomass and carbon storage potentials. Data were collected from 32 sample plots of 20 m x 40 m, established across the four sacred groves. In each plot, all woody plants with dbh ≥10cm were identified and their growth variables (dbh and height) measured. Non‐destructive allometric equation method was adopted for the estimation of volume, biomass and carbon stock production. The number of families and tree species encountered in the groves (understory and overstory layers) ranged from 22 to 32 and 41 to 85, respectively. The four groves had high Shannon‐Wiener diversity index (2.63 ‐ 3.55). They had high volume yield (244.99 m3 ha‐1 to 343.08 m3 ha‐1), biomass production (87.8 t ha‐1 to 231.86 t ha‐1) and carbon stock (43.9 t ha‐1 to 115.9 t ha‐1), with potentials for continuous growth as evidenced by the presence of young trees in the lower canopy. Thus, besides being good biodiversity conservation method, sacred groves act as sink of atmospheric CO2 considering their high biomass and carbon accumulation. The use and protection of sacred groves by indigenous people has enhanced tree species diversity, improved carbon sequestration and production of other forests ecosystem goods and services, thereby mitigating climate change and its effects.

ArticleKnowledge and perception of senior civil servants on the environmental and social service functions of urban forestry
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.This study was conducted to assess the Knowledge and Perception of Senior Civil Servants on Social and Environmental Services of Trees in Federal and Oyo State Secretariats. Two hundred copies of questionnaire were administered. One hundred each for Federal Secretariat staff and the State Secretariat staff. In all, 187 copies were retrieved. Purposive sampling technique was adopted for the study and data collected were analyzed with descriptive statistics and Chi-square (X2). The results showed that the senior civil servants are well educated with over 40% having B.Sc at the federal and state secretariats in general, ND has 20.9%, HND (19.3%), BSc (43.9%) and MSc (16%). and the field of study of the majority is Social sciences followed by sciences as follows 51.9%, 25.7%, 17.6% and 4.8% of the respondents respectively studied Social science, Science, Agric/Forestry and Technology. Above 70% of the respondents are aware of the presence and benefits of tree around their office premises and street they live in. of all the benefits of trees in their surrounding, Cooling the environment has the highest percentage of about 40%. On the danger posed by urban trees, Trees falling on roads because of windstorm has the highest percentage of 72.8%. The Awareness on the benefits of trees on Social and Environmental services is very high (above 70%) among the respondents with all the statements such as Trees can reduce energy needs for refrigeration and air conditioning through provision of shade and reduced air temperatures thereby reducing the emission of pollutant chlorofluorocarbons (CFC). Based on the knowledge of urban forestry majority of the respondents are willing to conserve urban trees. Good policy that can bring about development of forestry sector in Oyo state is achievable because it was observed that the senior civil servants at both federal and state secretariats had enough knowledge and perception about the importance of urban trees.
