In recent years natural fibre production has taken on considerable appeal because of new industrial applications in environmental friendly products and growing demand for fibres could contribute to social welfare of poor farmers in developing countries. The new uses of natural fibres are part of highly technical green solutions for problems in the industrial and consumption regions but it may be asked whether this demand really addresses social and ecological issues in regions of primary production. These issues are examined in the Brazilian Amazon where recently a composite fibre sheet factory was opened and fibre cropping is making a comeback after decades of economic stagnation. It is shown here that the expansion of the activity, while significant, has not yet reached the scale of the past, but the market is promising, particularly in the automotive industry, which could further stimulate jute and malva production in the region.

The system dynamics approach is a holistic way of solving problems in real-time scenarios. This is a powerful methodology and computer simulation modeling technique for framing, analyzing, and discussing complex issues and problems. System dynamics modeling is often the background of a systemic thinking approach and has become a management and organizational development paradigm. This paper proposes a system dynamics approach for studying the importance of infrastructure facilities on the quality of primary education system in a developing nation. The model is built using the Cross Impact Analysis (CIA) method of relating entities and attributes relevant to the primary education system in any given community. The CIA model enables us to predict the effects of infrastructural facilities on the community's access of primary education. This may support policy makers to take more effective actions in campaigns that attempt to improve literacy. Modeli sistemske dinamike so celovita metoda reševanja kompleksnih problemov s pomočjo scenarijev. Omogočajo, da skupaj z metodo računalniške simulacije analiziramo kompleksne probleme. Modeliranje z metodo sistemske dinamike je pogosto osnova za sistemsko razmišljanje in predstavlja managersko in organizacijsko razvojno paradigmo. V članku je opisan pristop na osnovi sistemske dinamike pri raziskavi pomembnosti infrastrukturnih zmogljivosti na kakovost osnovnega izobraževanja v državi v razvoju. Model je izdelan s pomočjo navzkrižne analize vpliva (Cross Impact Analysis - CIA), metode, ki primerja entitete in atribute značilne za osnovno izobraževanje v neki dani skupnosti. Model CIA omogoča, da predvidimo vpliv infra­strukturnih zmogljivosti na dostopnost te skupnosti do osnovnega izobraževanja. To lahko pomaga javnim odločevalcem, da bolj učinkovito planirajo akcije, ki poskušajo izboljšati pismenost.
