Diversity is the natural state of the world (Harmon 2001). It is the quintessence of the evolutionary process as found in the natural world in its multiplicity of flora and fauna called biological diversity and in the constructed world in its multiplicity of cultures called cultural diversity. Language diversity is part of the co-evolution of humans with ecological diversity and it is comparable with the evolution of diversification of species. Languages are the core component of the ecologically evolved cultural diversity, which enable representation and transmission of the core aspects of cultures for acquisition by succeeding generations of the community and for interaction with other contemporary communities. It is natural for cultural diversity to emerge and sustain itself through language diversity. It is established empirically (Harmon 2002) that the diversity in nature and culture are integrally related and they are connected with the development of ecosystems and with their sustainability. This has given rise to the concept of biocultural diversity as a unified phenomenon. Most of the specialists in the respective fields of study of nature and of culture and the common people seem not to be aware of the connection between diversity in nature and culture. The awareness of the common people about the connection between culture and language is more socio-political and psychological and less philosophical in nature. One piece of evidence is that an increasing number of minority linguistic communities transplanted in the midst of a dominant linguistic community ask seriously the question whether they can maintain their culture without their language.
It is a natural assumption that international development programs lead to direct improvements in lives around the world. Decreasing rates of under-five mortality from malaria? Absolutely. Improving lives in the wake of unimaginable destruction from natural disasters? Without question. It was under these obvious assumptions that I worked for years on various development programs as part of a large government agency. However, I quickly realized that this dominant model of development – one that often takes a Western approach to what progress looks like and applies it to people in all parts of the world regardless of their own values – does not fare so well in empowering cultures, languages or local solutions. With time I saw clearly that in addition to building health clinics, schools, and green revolutions, I was in some cases unknowingly contributing to the creation of a Western monoculture and the destruction of beautifully diverse cultures and languages that hold immeasurable value.
What do we need to do to further promote biocultural diversity conservation? Since the existence of an “inextricable link” between cultural and biological diversity was affirmed in the pioneering 1988 Declaration of Belém, the field of biocultural diversity (BCD) has grown organically out of a variety of sources in the natural, social, and behavioral sciences,
