Book (stand-alone)Blue-green algae for rice production. A manual for its promotion
FAO Soils Bulletin No. 46
1981Also available in:
No results found.This manual is designed to give detailed, practical advice on the various methodologies of organic recycling. Blue-green algae form a self-sufficient system which is capable of fixing atmospheric nitrogen in organic forms and which grows upon a free water surface. It is thus ideally suited for propagation in rice fields. The development and use of blue-green algae require special techniques. The manual summarizes the present status of algal biofertilizer technology for rice with practical inform ation for its adoption by agricultural extension personnel and subject matter specialists. If properly extended, the technology holds the promise of providing 25-30 kg N/ha every season to the growing crop. It also holds the promise of generating rural income and employment. The ultimate success of the technology depends not only on creating an awareness but also on building a trained manpower reserve capable of applying the existing knowledge and carrying out further research. -

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.
