Biological
diversity is a broad term that includes the genetic diversity within a specie
and variety of species as well as the range of communities and ecosystems.
Basically it is variety of life on earth. Biological diversity resources are
the pillars upon which we build civilization. But unfortunately due to
agronomic activities biological diversity is rapidly declining that ultimately
threatens the nature and people alike. Due to these circumstances and
international Day of biological diversity seeks to increase awareness and
highlight the importance of biodiversity and global issues on biodiversity loss.
First
international Day for biological diversity was created by UN General Assembly
in 1993. Originally this day was proclaimed on December 29 but in December 2003
UN General assembly changed the date to may 22 to avoid clashing with the
various international holidays in late December. CBD decides at theme for this
day every year. This year biological diversity Day is being celebrated under
the theme "we are part of the solution". MS team creates to continue
momentum generated from the last year theme "our solutions are in
nature".
Aim:
This day seeks to achieve the global
understanding and awareness about the issues, loss and importance of protecting
biological diversity. The purpose of selected theme is to emphasize on working
together at all levels to build a sustainable living future in harmony with
nature. Mainly this day is dedicated to protect the biological resources and
global biodiversity.
Threats to
biodiversity:
Decline of
species are the result of combination of factors.
·
Global
Assessment Report on Biodiversity and Ecosystem Services in 2019 by IPBES
stated that the main global drivers of biodiversity are climate change,
invasive alien species, over exploration of natural resources, pollution and
urbanization.
·
The
global report elaborate that human activities are responsible for 75% of
biodiversity loss in terrestrial ecosystems.
·
As
concerned for landuse, 85% of wetlands and 75% of land surface across the world
has been altered.
·
Up
to 1 million species are threatened with extinction.
·
33%
of marine fish stock harvested unsustainably.
Importance
of biological diversity:
Biological
diversity is the backbone of survival on earth with uncountable intrinsic and
instrumental values.
·
Plants
provides over 80% of human diet.
·
According
to IPBES; 3-4th of food crops rely on animal pollination.
·
4
billion people primarily rely on natural medicines.
Scenario
of Pakistan:
Pakistan
possess a variety of world's ecological regions due to its immense latitudinal
and altitudinal variations. Arid and semi arid regions possess significant
portion of biodiversity in 80% land area of the country. But unfortunately
during the last 2-3 decades Pakistan's biodiversity is under immense pressure
due to over exploitation of natural habitats.
Further more
factors like deforestation, overgrazing, soil erosion, salinity and
waterlogging are causing major threats to the remaining biodiversity and
nation's other natural and agricultural ecosystems. Therefore protected areas
system has been established in country for in situ conservation of
biodiversity.
Need for
Action:
Loss of
biological diversity is a matter of concern because they possess such intrinsic
and instrumental values that are self-explanatory. All the assessment indicates
that solutions existed if we consider them seriously for taking action; as we
are the part of solution.
We have to
invest in biodiversity from every aspect, as it can strengthen the adaptive
capacity of food systems to provide healthy and relevant nutrition for
sustaining life.
Biological
Diversity Legislation:
·
The
objective of halting biodiversity loss and promoting sustainable use of
ecosystems are included in sustainable development goal 15.
·
Red
list is created by IUCN in 1964 for highlighting the threatened species.
·
CITES
treaty 1970 is adopted by 150 countries for controlling international trade of
wild fauna and flora.
·
Convention
on biological diversity (CBD) 1992 has been designed for conservation and
sustainable use and the equitable sharing of benefits for biological resources.
·
In
Pakistan, National Conservation Strategy (NCS), Pakistan Environmental
Protection Agency (PEPA) and Biodiversity Action Plan (BAP) are working for
conservation of biological diversity.
What to
do?
To halt these
losses, it is compulsory to transform people's roles, actions and relationships
with biodiversity because all efforts to reverse the loss would be of no value
without local participation. There is a need for all governments, local
communities and NGOs to work together on comprehensive plans for biodiversity
conservation.
As the part
of solution local communities should be involved and further support should be
obtained from relevant institutions in sustainable use initiative. Success in
this matter begins with the determination of individuals and coordinated
efforts on every scale and also involving the work of both scientists and
policymakers.
Protection
demands stepping back to look over the picture, seeing how people relate to the
rest of natural world and examining how we can do so in more sustainable ways.
