A literature review, M.Banja, JF Dallemand, European Commission, Joint Research Centre …………. page 243 Foreword An important challenge in the twenty-first century is to supply the growing world population that requires more and more energy per person with sufficient energy. Today, this energy supply is mainly based on fossil energy carriers that have large drawbacks, like the impact on climate change and the depletion of the resources. Renewable energy, for example wind energy, solar energy or bioenergy, might be important energy sources in the future. Bioenergy is renewable energy from organic material. It corresponds to three main feedstock categories (agriculture, forestry & waste) for three main uses (transport, heat & electricity). The development of bioenergy is often considered as a positive option due to its contribution to the mitigation of climate change, agricultural and rural development, energy security and innovation policies. Nevertheless, concerns have been raised during the last few years about risks or bad practices, sometimes evolving into large scale controversy, especially in relation to greenhouse gas emissions. The need to ensure that bioenergy development will be based on sustainable water management is in our view essential, taking into account the need to increase food production and to simultaneously accommodate other uses of water resources, both for quantity & quality. This publication thus contains data and information related to methodologies of impact assessment, practical case studies, scenario analysis, discussion of sustainability certification schemes, all focusing on bioenergy & water. This publication has been prepared as a follow-up of the Session on Bioenergy & Water of the Sixth World Water Forum (Marseille, 2012). This document was prepared by the Joint Research Centre of the European Commission, with the support of the University of Twente (the Netherlands) and of the International Energy Agency Bioenergy Task 43 (Biomass Feedstock for Energy Markets). This Report is based on voluntary contributions and we wish to thank all the contributors from Argentina, Australia, Brazil, the European Commission, France, Germany, India, the International Energy Agency, the Netherlands, South Africa, Sweden, the United States, for their availability and their scientific input. We do hope this document will become a useful reference for those interested in the sustainability of bioenergy and will contribute to the diffusion of good practices of water management at global, national or local level. J.F. Dallemand (European Commission Joint Research Centre) P.W. Gerbens Leenes (University of Twente) The Biofuel and Bioenergy Roadmaps of the International Energy Agency A.Eisentraut International Energy Agency, Renewable Energy Division, 9 Rue de la Fédération, 75739, Paris Cedex 15, France Abstract Bioenergy is the largest source of renewable energy today and can provide heat, electricity, as well as transport fuels. The Technology Roadmaps Bioenergy for Heat and Power, and Biofuels for Transport highlight the importance of bioenergy in providing renewable electricity, heat in buildings and in industry, as well as low-carbon biofuels in the transport sector. The roadmaps envisage world total primary bioenergy supply increasing from 50 EJ today to 160 EJ in 2050, with 100 EJ of this for generation of heat and power. By 2050 bioenergy could provide 3 000 TWh of electricity, i.e. 7.5% of world electricity generation. In addition heat from bioenergy could provide 22 EJ (15% of total) of final energy consumption in industry and 24 EJ (20% of total) in the buildings sector in 2050. Biofuels could provide 32 EJ of low-carbon fuels, meeting 27% of world transport fuels demand in 2050. In total this could provide 3.6 Gt CO2-equivalent (CO2-eq.) emission savings per year in 2050 compared to a business-as-usual scenario, if the feedstock can be produced sustainably and used efficiently, with very low life-cycle GHG emissions. The roadmap identifies key actions by different stakeholders in the bioenergy sector, and sets out milestones for technology development in order to achieve a doubling of global bioenergy supply by 2050. It addresses the need for further research and development (R&D) efforts, highlights measures to ensure sustainability of biomass production, and underlines the need for international collaboration to enhance the production and use of sustainable, modern bioenergy in different world regions. 1. Background Current trends in energy supply and use are unsustainable–economically, environmentally and socially, and International Energy Agency (IEA) analysis shows that without decisive action, energy-related greenhouse gas (GHG) emissions could more than double by 2050, and energy security could be seriously compromised in many regions (IEA, 2012). To address these challenges, the IEA, at the request of the G8, is developing a series of technology roadmaps for some of the most important low-carbon technologies needed to reduce global energy- 1 related CO2 emissions by 50% in 2050 compared to 2005 levels. The basis for all roadmaps is the 2°C scenario (2DS) developed for the IEA publication Energy Technology Perspectives (IEA, 2012). Two recently published roadmaps are focussing on Biofuels for Transport and Bioenergy for Heat and Power. Each roadmap develops a growth path for the covered technologies from today to 2050, and identifies technology, financing, policy and public engagement milestones that need to be achieved to realise the technology’s full potential (for more information and to download the roadmaps

Therefore, the objective of this work was to carry out a collection of publications on NTFPs in Brazil, until 2019, available in the Scopus database, presenting a bibliometric review and the state of the art of this theme from the evaluation of these publications, discussing the challenges of Brazilian legislation on NTFPs. After screening the articles of interest, 196 documents were evaluated, in which they were observed institutions and authors, analyzing networks of citations and terms used, areas of forest sciences and sciences that encompass the most explored biomes and the most studied species. The results showed that the concern to research on NTFPs in Brazil began in the 1990s, with an increase in the number of publications over the years. Besides that, the research on NTFPs is multidisciplinary, with emphasis on the areas of Agricultural and Biological Sciences and Environmental Science.

Acta biol. Colomb. 2020;25(1):104-111. DOI: http://dx.doi.org/10.15446/abc.v25n1.77701 ABSTRACT Attalea nucifera is a threatened palm endemic to the Magdalena River basin in Colombia. In the past its seeds were consumed by the inhabitants of the town of Guaduas, Cundinamarca, although currently its use is less frequent. To assess the productive potential of this palm, we studied its phenology, biometric parameters, and fruit productivity in a forest relict in Guaduas. Field work was carried out between April 2016 and March 2017. The reproductive cycle of this species lasted approximately 12 and a half months from bud to fruit ripening. Although bud production occurred throughout the year, it increased during periods of greatest rainfall. Flowering peaks occurred towards the end of the rainy season and fruits ripened towards the period of low rainfall. We found a positive correlation between the number of leaves in the crown and the production of reproductive structures (rs = 0.447, p = 0.004).

  • 1 Ornamental Palms
    1 Ornamental Palms: Biology and Horticulture T.K. Broschat and M.L. Elliott Fort Lauderdale Research and Education Center University of Florida, Davie, FL 33314, USA D.R. Hodel University of California Cooperative Extension Alhambra, CA 91801, USA ABSTRACT Ornamental palms are important components of tropical, subtropical, and even warm temperate climate landscapes. In colder climates, they are important interiorscape plants and are often a focal point in malls, businesses, and other public areas. As arborescent monocots, palms have a unique morphology and this greatly influences their cultural requirements. Ornamental palms are over- whelmingly seed propagated, with seeds of most species germinating slowly and being intolerant of prolonged storage or cold temperatures. They generally do not have dormancy requirements, but do require high temperatures (30–35°C) for optimum germination. Palms are usually grown in containers prior to trans- planting into a field nursery or landscape. Because of their adventitious root system, large field-grown specimen palms can easily be transplanted.
