This study provides basic taxonomic data on Liliopsida (monocotyledons) and Pteridophyta of the representative homestead areas of Dhaka, Gazipur, Manikganj and Tangail districts of Bangladesh. The monocotyledons and pteridophytes, growing naturally in the homstead areas, are composed of total 137 and 16 species under 84 and 13 genera belonging to 22 and seven families, respectively. A total of 20, 13, 19 and 17 species respectively, occur exclusively in the homesteads of Dhaka, Gazipur, Manikganj and Tangail districts and only 22 species are common there. Poaceae with 53 species is the largest family and Cyperus with 12 species is the largest genus in monocotyledons. Pteridaceae with eight species and Pteris with three species are the better represented family and genus, respectively in pteridophytes. Total 136 species are appeared as herbs that are followed by 11 species of trees and six species of shrubs. A total of 119 species are documented as economically useful. This study identifies a number of active threats to the flora of the study area, and suggests to launch adequate management and awareness building programs for the homestead people in order to ensure effective conservstion and sustainable use and development of plant genetic resources in the homestead areas of this region.

On Farm

A global survey was conducted among a wide range of stakeholders to gain insight into the state of on-farm management (OFM) as a strategy for enhancing the conservation and sustainable use of plant genetic resources for food and agriculture (PGRFA). The results show that OFM is not considered a priority in national PGRFA programmes (NPGRPs), and that OFM practitioners and their organizations are not always aware of, or involved in, NPGRPs. The survey also highlighted the lack of awareness, understanding and collaboration between OFM practitioners and the managers and policy-makers associated with NPGRPs. The outcome of the analysis supports a hypothesis that OFM is, to a large extent, supported by stakeholders who are not directly engaged in the conservation and use of PGRFA, and therefore not associated with NPGRPs. This should be taken into consideration when seeking to improve the performance and impact of national programmes, and their commitment to safeguard PGRFA and contribute to food security, poverty alleviation and sustainable agriculture.

This study demonstrates that the vascular flora of the Rangpur district area consists of 825 species under 537 genera and 139 families. The pteridophytes and gymnosperms are represented by 25 and seven species, respectively, whereas the angiosperms by 793 species including 582 species of dicotyledons (Magnoliopsida) and 211 species of monocotyledons (Liliopsida). Poaceae with 67 species, representing 8.12% of the flora, is appeared as the largest family, and followed by Asteraceae, Fabaceae, Araceae, Malvaceae and Euphorbiaceae that collectively constitute 17.94% of this flora. Persicaria comprising 10 species is recorded as the largest genus, and followed by Ficus, Euphorbia, Solanum, Albizia and Brassica. About 59.71% taxa of this flora are herbs, 21.71% trees, 14.72% shrubs and the rest are palms, lianas, and bamboos. Erect herbs forming 35.22% of the flora comprise the most common life-form. In this flora, almost 64.29% taxa are native and the rest 35.71% are exotic. Nearly 62.61% taxa of the flora are found in wild, 26.90% as planted and 10.49% as cultivated. About 35.46% of the species commonly occur throughout all upazilas of this district. Most of the species are harboured in fallow lands, roadsides, gardens, and homesteads. All species of this district flora are known as economically useful. Most of its habitats and ecosystems are exposed to different threats. Adequate measures with effective management plans should be adopted and implemented for the sustainable use, improvement and conservation of this precious flora. Bangladesh J.

Science Cafe

Science Cafés are held in many towns and cities across the world for the promotion of scientific culture and the understanding of our daily lives, which we live in. They provide a platform for interaction and dialogue between scientists, researchers, businesses and the community on trends towards current scientific issues the extent of their impact on culture and society. The Oman Animal and Plant Genetic Resources Center (OAPGRC) Science Cafe is a forum for the discussion of important and interesting scientific topics and issues. Since May 2013 to December 2015, OAPGRC has held a series of science café sessions on topics related to biodiversity, food security, climate change, pollution and sustainable use. The OAPGRC science café is the first in Oman to be put on the international map of scientific cafes around the world.  Reviewing the data on the outcomes and performance of these sessions indicates that the session attendance and active participation was 51% by men and 49% women. This is an exceptional case where the interest is almost equal between the genders. As for the age group, the highest percentage 49% was of a class of young people aged between 18-25 years. Followed by the age group (26-35 years) which was 30%. The lowest percentage was 21% for the age group of above 35 years. The experience of the science café in Oman has been proved as a major success for both the scientific and social aspects. Therefore there are different plans to maintained and develop it in the near future.

<p>The high diverse of plant genetic resources for food and agriculture (PGRFA) in Indonesia needs to be conserved for sustainable use to achieve food security despite a still growing population. Therefore, database and information system which could add value to the PGRFA have been developed by many international initiatives and conventions which impact to national level. Two international agreements that Indonesia intensively involved to govern access and share the benefit arising from the use of the valuable PGRFA are the International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA) and the Nagoya Protocol of the United Nations Convention on Biological Diversity. Agriculture development in Indonesia, however, is still faced many challenges. This review described and discussed the high biodiversity in Indonesia, utilization and conservation of PGRFA, supporting regulation and policy on PGRFA along with the progress of database and information system. Overall, promoting conservation and the sustainable use of PGRFA is a key goal of various national, regional, and global efforts, initiatives, and agreements governing them for human well-being.</p>

Plant genetic resources for food and agriculture, a common concern of all countries, are critically important for the sustainable production of the significantly more nutritious food needed to feed an ever-growing population in the face of climate change and other drivers. This entails the translation of the potentials encoded into their genetic blueprints into improved productivities. The relevant international agreements, instruments and mechanisms, which address the conservation, sustainable use and access and benefit-sharing for these resources, are reviewed along with their remarkable contributions to food security and nutrition. The chapter also highlights the state-of-the-art for the scientific and technological methods used to conserve and add value through genetic gains to these resources. Underscoring the importance of collaborations at various scales, we call for continued global coordination and partnerships on the internationally agreed activities for conserving effectively and deriving the most benefits sustainably from these irreplaceable resources.

This chapter reviews the methodologies developed to assess the extent of diversity of PGRFA at species, variety, and genetic level and examines the efforts made at global level in monitoring them at different scales. Efforts have been made to halt the loss of biodiversity (including genetic diversity) by United Nations Organizations (FAO, UNEP, UN) at setting of global targets (second Global Plan of Action on conservation and sustainable use of PGRFA, Aichi Targets and Sustainable Development Goals) and indicators have been established to monitor progress towards them. Yet none of the targets on genetic diversity have been achieved, due to a lack of implementable monitoring system that would allow progress to be accurately monitored. Further research is needed to improve the methodologies for monitoring plant genetic resources, particularly at the varietal and genetic level. The chapter discusses the opportunities and challenges as well as provides recommendations for future conservation and monitoring strategies that may safeguard PGRFA for posterity.

On Farm

Millions of farmers depend on the use of local crops and varieties for their food and livelihood. These resources constitute a reservoir of alternative traits and characteristics, which allow us to diversify crops, foods and farming methods and provide material for targeted plant breeding. Still, many countries lag behind in providing support to farming communities for the maintenance and use of plant genetic resources for food and agriculture (PGRFA). A global survey was conducted among a wide range of stakeholders to gain insights into the state of on-farm management (OFM) as a strategy for enhancing the maintenance and sustainable use of PGRFA. The survey showed that a wide range of stakeholders provide de facto support to OFM and that the practices they consider critical are focused on building capabilities in local communities. This supports the fact that the management of crop diversity on farm can be promoted in a variety of ways, depending on the specific context, and that local solutions are needed to successfully support OFM. Partnerships and networks should be considered as one of the critical means to promote OFM, as they involve a diversity of stakeholders working towards common goals. The survey further showed that many respondents currently contribute to existing networks relevant to OFM, but that these networks are mainly nationally or internationally oriented and might therefore exclude crucial local stakeholders, such as community-based organizations. Therefore, mechanisms should be put in place to strengthen the collaboration between stakeholders and networks, especially at the local level.

Climate change is an unequivocal fact and its impacts are already perceptible today. Climate change will profoundly alter the present conditions of agriculture in almost all countries with variable severity from region to region. On one hand unpredicted changes in climatic parameters are likely to threaten the production and productivity of economically important plant species particularly that of food crops, at the same time agriculture productivity requires significant increase to meet the expected growth in demand for food by the ever increasing world population. Conservation and sustainable use of diversity present in plant genetic resources and traditional knowledge of germplasm within and among plant species represent economic, scientific and societal value which has tendency to solve the food security problems erupt due to expanding global population. An advance made in biotechnology field such as in vitro culture technology, cryopreservation and molecular markers technology has generated significant contributions to improve the methods of conservation of rare and endangered plant genetic resources and traditional knowledge of germplasm and their valuable management in an effective way. A strategic and forward vision for conservation of plant genetic resources and traditional knowledge of germplasm and sustainable use of plant resources in the 21st century is of far reaching significance for sustainable development.
