ArticleJournal 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.

ArticleJournal 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.

ArticleJournal articleWildlife status and ecotourism potentials of Lekki Conservation Centre, Nigeria
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Ecotourists are attracted to environments with unique nature-based resources including wildlife hotspots. Information about the status of wildlife in Lekki Conservation Centre after a decade which is required for biodiversity policy making is lacking. Day foot patrol to monitor wildlife in Lekki Conservation Centre was carried out from January to December, 2020 and wildlife species present were identified. A total of 300 tourists were sampled from March to July 2021 using a structured questionnaire and interview. Data of animals sighted by the tourists were compared with records of animals sighted from March to July, 2010 as recorded in the Protection Report Diary. The findings indicated a decline in squirrel (Heliosciurus gambianus) and bushbuck (Tragelaphus scriptus) population while the endangered Phataginus tricuspis recorded as sighted 5 times in the Protection Report Diary was not sighted during the survey. A list of fauna in LCC is provided as result from the patrol although some parts of the forest were inaccessible. Species diversity in the Protection Report Diary (in 2010) was higher compared to total number of wildlife species sighted by visitors (in 2021) indicating that some wildlife species in LCC declined within 10years.

Book (stand-alone)Technical studyAquatic biodiversity in Rice-Based Ecosystems
Studies and reports from Indonesia, Lao PDR and the Philippines
2014Also available in:
No results found.This report contains the assessments of availability and use of aquatic organisms in rice ecosystems conducted in late 2013 in four sites in Indonesia (three in West Java and one in Bali), three sites in Xieng Khouang Province in Lao People’s Democratic Republic and four sites in three provinces on Luzon Island in the Philippines. A standard methodology was applied in conducting the assessments. The documentation was made of the animal and plant organisms found in the study sites and being colle cted by the people, the methods and tools to capture or gather them, and their uses as food, medicine and for other purposes. Local people have generally acknowledged a general decline in the abundance and diversity of the species. Factors included the intensification of rice cultivation accompanied by the use of chemical inputs, increasing exploitation driven by population increase and in some cases a high market demand for some species, and destructive fishing. Recommendations range from expan ding the study period to observe biodiversity changes during other seasons of the year, locally tailored management measures using the study sites as pilot areas, national policy that protect the ricefield ecosystem biodiversity and enhance their flow of services, extending the assessment to the value chain of the species which have an increasing market demand, to institutional arrangements and collaboration between national, regional and international agencies and organizations. Awareness raisi ng of the value of the products and services of ricefield ecosystems and capacity building for communities and government agencies for management of the ecosystem were strongly recommended. This was taken one step further in Lao PDR where a small pilot project was undertaken with the Department of Livestock and Fisheries, to develop improved methodologies for integrating work on the valuation of aquatic resources into local policy development processes. This included the development of local cap acity and demonstrated that a facilitated process of collaboration between local communities and local government agricultural extension officers, can successfully influence local policy and establish institutional mechanisms to sustain this work at both local and national levels. -

BookletManual / guideAgricultural extension manual for extension workers 2019
Also available in:
No results found.In the context of sustainable agricultural development, agricultural extension has a very crucial role to play. The tasks and responsibilities of extension service will need to be broadbased and holistic in contents and scope, thus beyond agricultural technology transfer. Its normal task of transferring and disseminating to farmers appropriate agricultural technologies and good farm practices would not be sufficient. Extension agencies, services, and workers will need to exercise a more proactive and participatory role and serve as knowledge/information "brokers", initiating and facilitating mutually meaningful and equitable knowledge-based transactions among agricultural researchers, trainers, and primary producers. To improve its cost-effectiveness, proper strategies to advocate favorable and explicit agricultural extension policies are needed. Modern strategic planning and quality management tools and approaches should be utilized in developing or restructuring extension organizations or institutions. More innovative methods must be developed to identify systematically farmer’s problems and felt needs, and to help formulate and set agricultural research agenda based on such needs and problems. In short, there is a need to develop and improve the conceptual, technical, and operational methods and tools in order to strategically plan, efficiently manage, and scientifically evaluate a problem-solving, demand-driven and needs-based agricultural extension program. This manual is a practical guide for extension workers in agriculture. It contains simple, easy to follow tools on the commonly used extension methods and an outline of how extension may be planned and implemented.
