Biodiversity, a contraction of the phrase “biological diversity,” can be traced to the first usage by Walter G. Rosen during a planning meeting for the 1986 National Forum on Biodiversity held in Washington, DC, while the first appearance of the word in the print literature likely occurred with the 1988 publication of the proceedings of the said conference. The 1992 Convention on Biological Diversity defines ‘biodiversity’ to mean “the variability among living organisms from all sources including, inter alia, terrestrial, marine and other aquatic ecosystems and the ecological complexes of which they are part: this includes diversity within species, between species and of ecosystems”.
The United Nations Educational, Scientific and Cultural Organization (UNESCO) on the other hand defines ‘biodiversity’ as the ‘diversity of all living forms at different levels of complexity: genes, species, ecosystems and even landscapes and seascapes’. Biological diversity or biodiversity has also been defined as ‘the variety of the planet’s living organisms and their interactions’. The term is meant to encompass all of life’s variation, expressed in genes, individuals, populations, species, communities and ecosystems. A broader definition of ‘biodiversity’ has been propounded as referring to three dimensions within which variability occurs: genetic, meaning the variation of genes within a species, sub-species or population; population/species, meaning the variation between living species and their component populations at different spatial scales (local, regional or global); and community/ecosystem, meaning the variation within ecological complexes of which species are a part.
These definitions are relevant especially in the context of Sustainable Development debate as they reflect the important role that biological diversity can and indeed plays in meeting the essentials of realising Sustainable Development goals such as food security, alleviating poverty, among others. The World Bank argues that while biodiversity provides many instrumental benefits, from food and fuel to recreation, even where biodiversity is not immediately instrumental, it represents global public goods that must be protected, if only for their potential value in the future.
Scholars identify three forms of biodiversity such as alpha (genetic diversity), beta (species richness) and gamma (ecological diversity) and the services that accrue from biodiversity include materialistic gains, ecological services (flood control, climate maintenance, and nutrient cycling), and nonmaterialistic benefits such as recreation. This paper critically discusses some of the major approaches that have been adopted globally in conserving all the above mentioned forms of biodiversity. The paper also highlights the salient provisions of the 1992 Convention on Biological Diversity, the key international legal instrument on biological diversity conservation.
It has rightly been observed that while ‘biodiversity can be greatly enhanced by human activities, it can also be adversely impacted by such activities due to unsustainable use or by more profound causes linked to our development models’. This is despite the fact that biodiversity is considered to be very important for sustenance of all forms of life on earth. Biodiversity is essential not only to the proper functioning of earth systems, it is also key to the delivery of those ecosystem services that are crucial to human dignity and well-being including: the provision of potable water, food; soil fertility; maintenance of the ‘genetic library of biodiversity’ – an irreplaceable source of new innovations, pharmaceuticals and chemicals; and climate regulation – among others.
It is this scope of biodiversity that informs the concept of ecosystem services. Ecosystem services approaches prioritize those processes that contribute to human wellbeing; very different from a biodiversity conservation approach, which is concerned with identifying conservation management actions to promote the persistence of all biodiversity, including species or ecosystems that do not have an identified value for humans. Thus, it is suggested that when utilising ecosystem services approaches for conservation, planners and managers must be realistic and recognise that these approaches are not all encompassing and there are going to be gap species, ecosystems, and ecological processes whose conservation will require tools tailored to address those issues.
The ecosystem services approaches are inspired by the desire to give an economic assessment of these functions thus leading to the appearance of the concept of ecosystem services, that is, consideration with regard to their usefulness for humans. Arguably, ecosystem services are divided into four categories namely: provisioning services refer to natural products that are directly used by humans for food, clothing, medicines, tools, or other uses; cultural services provide recreational opportunities, inspiration for art and music, and spiritual value; regulating services include pest control and carcass removal; and supporting services, such as pollination, seed dispersal, water purification, and nutrient cycling, provide processes essential for ecological communities and agricultural ecosystems.
