Over the past few decades, there are evidences that scientific paradigm is changed from disciplinary to transdisciplinary approaches. The question of sustainability science, novel ways for production and coproduction of knowledge and a matter of accomplishment for real world problems represent a big challenge for scientific and academic community. Transdisciplinary team-based research, integration of knowledge from different disciplines and a view into complex societal problems from different perspectives can make a contribution for production of new, practice-oriented knowledge, applied for social problems solution. Going to the transdisciplinary approach is especially valuable in social sciences, where collaborative practice became a necessary normative.In this paper authors, first in the context of theoretical considerations describe possible applications of transdisciplinary research in Bosnia and Herzegovina, as post-conflict, transitional community. The second part of article there is emphasized transdisciplinary approach to the problem of juvenile delinquency in Tuzla Canton through research project: „Influence of different contexts of socialisation on the development of juvenile delinquency in post-war Bosnia and Herzegovina – Recommendations for prevention and intervention“ which is realised in four years from 2010 to 2014. Analysing of challenges and problems which this interdisciplinary research team was faced with, authors tried to explain that the way of transdisciplinarity is the way for bridging of different discipline perspectives and through research process finding out solutions applicable in practice. Looking for applicable and practical solutions and maintenance of sustainable strategies for socially relevant and real life problems in post-conflict communities is one of the priorities and challenges for universities, academic communities, government institutions and whole society.

The idea of modern society, which is recognized as important in the process of becoming more adaptive to changes in society, is the idea of lifelong learning. Lifelong learning represents the integration of formal, non-formal and informal learning. The paper tries, by theoretical analysis of significant scientific and legal sources, to answer the question whether the idea of lifelong learning is the factor of influence on the reduction (of risks) of poverty. The results point to the fact that lifelong learning in the declarative sense of the word,is identified as a mechanism for the efficient adjustment of the labor market and greater opportunities for employment, which in the end, according to the strategic objectives, should result in the reduction of poverty.
