Natural resources planners—especially those involved in forest management—are increasingly being challenged in their ability to “think on their feet” and speak interactively in cross-cultural co-management teams addressing issues of natural resources management. Team learning occurs in the discovery of the best conversations to initiate that will have the potential to discover the relevant questions to ask. Continuous identification and systematic resolution of strategic issues is best done by carefully respecting both oral and written means of communication. This paper reviews historic and recent trends in the re-discovery of a team learning process that honours spoken words and respectfully facilitates dialogue. Balancing orality and literacy in the context of adaptive co-management with communities will enable natural resource stakeholders to continually improve the relevance of their policy, research and management. Key words: oral tradition, natural resources management, adaptive co-management, problem-based learning

The aim of the work is to investigate the use of existing wood waste, the most effective method of obtaining lignin and to create composite material made from renewable natural resources. The work looked at the current wider use of wood resources - construction, energy and chemical processing. The current waste from the use of wood - lignin is investigated. And the complex and rational use of this waste without waste. Experimentally, lignin was obtained with two methods, alkali and acid, from different Latvian tree species. Experimentally obtained composite samples with different compositions - alkali / acid lignin (binder) and leafy tree ash / chips (filler). Also, composite materials are considered at different proportions, where the percentage of both binders and fillers changes. Experimental samples were pressed at different temperatures.

This article considers recent trends in federalism, with particular attention to revenue sharing of natural resources in the new federal system of Nepal. It begins with a general description of the federal system prevailing in other countries, revenue sharing pattern and possible ways that can be implemented in Nepal. The article concludes with an explanation of trends that set the direction for policy innovations in natural resources federalism and general thoughts about the future of federalism in natural resources law in Nepal, which in turn can be reflected in the new constitution. A model consisting of seven provinces based on five criteria (river and hydro-power; forest, wild life and national parks; population/ethnicity; geographic location; and road networks) is also proposed for restructuring new Nepal. Three levels (center, province and local/or community) of new Nepal federal system are proposed. Recommendations are made to be included in the fundamental right and state responsibility part of the constitution.

The paper uses waste from the production of synthetic rubbers, industry, various clays for effective ways to solve the socio-economic and environmental problems of preserving natural resources and preventing environmental pollution. The construction materials industry faces the most important task-the search for non-deficit raw materials that allow partially or completely eliminate expensive conditioned polymers, rubbers and obtain cheaper mastic roofing materials while maintaining their high physical, mechanical and operational properties. Thermomechanical curves of composite materials based on synthetic rubbers with additives were studied. It is shown that the softening of samples of roofing materials No. 325 and No. 326 begins at , 20 % deformation is achieved, respectively, at – (No. 325) and + (No. 326), a sharp increase in deformation is observed, respectively, with a loss of strength: 40 % (No. 325) and 20 % (No. 326). Based on these materials, reinforced mastic roofs have been developed, which have low values of crack resistance. The coefficient of water resistance depends on the base, i.e. the reinforcing materials.
