2016 Theme: Mainstreaming Biodiversity; Sustaining People and their Livelihoods
Biodiversity is the foundation for life and for the essential services provided by ecosystems. It therefore underpins peoples’ livelihoods and sustainable development in all areas of activity, including economic sectors such as agriculture, forestry, fisheries and tourism, among others. By halting biodiversity loss, we are investing in people, their lives and their well-being.
The thirteenth meeting of the Conference of the Parties to the Convention on Biological Diversity (COP 13) to be held in Cancun, Mexico from 4 to 17 December 2016 will focus on the mainstreaming of biodiversity within and across sectors, which is closely linked to this year’s IDB theme.
The United Nations General Assembly, by its resolution 55/201 of 20 December 2000, proclaimed 22 May as The International Day for Biological Diversity, to increase understanding and awareness of biodiversity issues. The date designated for the day was chosen to commemorate the adoption of the text of the Convention on 22 May 1992 by the Nairobi Final Act of the Conference for the Adoption of the Agreed Text of the Convention on Biological Diversity.
The day was first created by the Second Committee of the UN General Assembly in late 1993, and the UN General Assembly, by its resolution 49/119 of 19 December 1994, designated December 29th (the date of entry into force of the Convention of Biological Diversity) the International Day for Biological Diversity. However, it was difficult for many countries to plan and carry out suitable celebrations for the date of 29 December, given the number of holidays that coincide around that time of year.
Biodiversity, What Is It?
Biological diversity — or biodiversity — is the term given to the variety of life on Earth and the natural patterns it forms. The biodiversity we see today is the fruit of billions of years of evolution, shaped by natural processes and, increasingly, by the influence of humans. It forms the web of life of which we are an integral part and upon which we so fully depend.
This diversity is often understood in terms of the wide variety of plants, animals and microorganisms. So far, about 1.75 million species have been identified, mostly small creatures such as insects. Scientists reckon that there are actually about 13 million species, though estimates range from three to 100 million.
Biodiversity also includes genetic differences within each species — for example, between varieties of crops and breeds of livestock. Chromosomes, genes, and DNA-the building blocks of life-determine the uniqueness of each individual and each species.
Yet another aspect of biodiversity is the variety of ecosystems such as those that occur in deserts, forests, wetlands, mountains, lakes, rivers, and agricultural landscapes. In each ecosystem, living creatures, including humans, form a community, interacting with one another and with the air, water, and soil around them.
It is the combination of life forms and their interactions with each other and with the rest of the environment that has made Earth a uniquely habitable place for humans. Biodiversity provides a large number of goods and services that sustain our lives.
The Value of Biodiversity
Protecting biodiversity is in our self-interest. Biological resources are the pillars upon which we build civilizations. Nature's products support such diverse industries as agriculture, cosmetics, pharmaceuticals, pulp and paper, horticulture, construction and waste treatment. The loss of biodiversity threatens our food supplies, opportunities for recreation and tourism, and sources of wood, medicines and energy. It also interferes with essential ecological functions.
Our need for pieces of nature we once ignored is often important and unpredictable. Time after time we have rushed back to nature's cupboard for cures to illnesses or for infusions of tough genes from wild plants to save our crops from pest outbreaks. What's more, the vast array of interactions among the various components of biodiversity makes the planet habitable for all species, including humans. Our personal health, and the health of our economy and human society, depends on the continuous supply of various ecological services that would be extremely costly or impossible to replace. These natural services are so varied as to be almost infinite. For example, it would be impractical to replace, to any large extent, services such as pest control performed by various creatures feeding on one another, or pollination performed by insects and birds going about their everyday business.
The current decline in biodiversity is largely the result of human activity and represents a serious threat to human development. Despite mounting efforts over the past 20 years, the loss of the world's biological diversity, mainly from habitat destruction, over-harvesting, pollution and the inappropriate introduction of foreign plants and animals, has continued. Biological resources constitute a capital asset with great potential for yielding sustainable benefits.
Urgent and decisive action is needed to conserve and maintain genes, species and ecosystems, with a view to the sustainable management and use of biological resources.
