ArticleOpportunities and limitations of non-wood forest products in the participatory guarantee systems of the plurinational state of Bolivia

No results found.Non-Wood Forestal Products (NWFP) offer regular incomes for collectors, producers in developing countries and they are considered as a livelihood strategy at tropical areas. In this study, the use of tropical seeds to elaborate handicrafts is an example how these seeds are collected at the tropics, transformed and sold to final consumers. For this study, we selected the Value Chain Approach (VCA) to identify the involved actors, the values of collections, processing and consumption along the chains. These four tropical seeds value chains were: Abrus precatorius, Jacaranda mimosifolia, Chamaedora elegans, and Dypsis lutescens. The objective was to identify the opportunities and limitations of the NWFP in the Participatory Guarantee Systems (PGS) which are acknowledged into the Law 3525/2007 for the Promotion of the Organic Agriculture at The Plurinational State of Bolivia. There are no previous studies on Participatory Certification for NWFP at national level. The study was located at the secondary forest of the Valle del Sacta UMSS-Tropico unit. This study took place from January to November 2013. The major results were: women are much more involved into the NWFP collection and processing tasks as well as in the consumption stage; Processors earn the twice than collectors due to the value adding tasks in order to produce a new product such as earrings, necklaces and others; the need to develop a NWFP seal through the PGS; the development of a tropical seed bank to supply the increasing demand during the whole year; and the need to involve a financial service provider with the two technical services such as the UMSS1 and CAPROECO2. The principal limitations were: the lack of ecologic information of the seed producing species; the lack of a custody chain in order to keep a control and monitoring of the activities along the chains; and the lack of market information for the real supply and demand.

ArticleForest-based bioeconomy pathways with emerging lignocellulosic products: A modeling approach
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.The forest-based sector plays an important role in a growing bioeconomy. Long-term resource availability and allocation will be a major challenge for the bioeconomy development. Therefore, this study aims to assess how forest product markets could develop in a growing bioeconomy and which interdependencies occur between traditional and emerging forest-based subsectors. Especially, the demand for wood-based textile fibres could dynamically grow over the next decades while there might be conflicting demand for wood resources from traditional subsectors. Thus, we include dissolving pulp, lignocellulose-based textile fibres and chemical derivatives in our modelling assessment. For this purpose, we extend the product structure of a partial equilibrium model, the Global Forest Products Model (GFPM). We use an econometric approach to compute demand and trade elasticities of the emerging products. We parameterize the extended model with these elasticities and analyze three different bioeconomy scenarios. In the first scenario, the demand for woody biomass remains similar to the current pattern. In the second scenario, the use of woody biomass increases primarily to satisfy growing input demand from the energy sector. In the third scenario, biomass is increasingly used as input to produce diverse industrial and everyday products. The simulation results show that, in the third scenario, where the world is changing toward a sustainable bioeconomy, wood consumption pattern shifts away from fuelwood (-30% by 2050) and paper products (-32% by 2050) towards emerging products. In this context, the dissolving pulp subsector could outpace the continuously shrinking paper pulp subsector in 2050. For this development, the dissolving pulp subsector mainly uses released resources from the decreasing paper pulp production. Simultaneously, wood-based panels are increasingly applied (+196% by 2050) while the growth of sawnwood remains limited.

ArticleMonitoring bioeconomy: wood flows and sustainability
XV World Forestry Congress, 2-6 May 2022
2022Also available in:
No results found.Substitution of fossil resources by renewable ones represents the core of the so-called bioeconomy and as such is a key factor of sustainable economic development. In Germany, wood is produced sustainably and the most important renewable resource for material uses. Traditional uses play an important role. At the same time, new wood-based value chains are developed and wood-based process and product innovations occur. But are wood- and other bio-based solutions really more sustainable? What effects occur along value chains due to increased wood use? In order to answer these questions and to steer bioeconomy development, production, processing and use of wood and other biomasses need careful monitoring. Our approach for monitoring resource base and sustainability of German bioeconomy approaches these issues in two complementary ways: on a sectoral and material flow-based level. In material flow-based analysis, all possible processing and manufacturing steps of a certain resource as e.g. wood from production (harvest or catch) to final disposal are described and quantified. Therefore, it allows for a detailed analysis of specific value chains as compared to a sectoral assessment of the bioeconomy. Thus, material flow-based analysis provides data for evaluation of efficient use of resources and substitution of fossil resources in production, processing and manufacturing as well as use and post-use phases. As of today, biomass is already used in multiple ways but data to quantify all used amounts in detail is not available. Material flow-based analysis is also the basis for the assessment and comparison of sustainability effects of bio-based material flows and their products with non-bio-based. As an example, we quantify global warming and eutrophication potential associated with wood pallets, representing the material flow of coniferous sawn wood.
