Zadie Neufville writes for IPS News about action being taken to preserve Jamaica’s biodiversity, particularly in the face of ongoing environmental degradation and climate change:

Jamaican authorities are going all out to achieve environmental sustainability as one way of minimising the expected impacts of climate change on the local biodiversity.

There is no up-to-date inventory of the island’s flora and fauna, and a shortage of adequate data collection devices, which researchers say are needed to begin climate impact studies and adaptation planning in ecosystems management.

But, by working toward the seventh Millennium Development Goal (MDG) – a series of development and anti-poverty targets agreed by U.N. member states in 2000 – authorities hope to establish the principles of sustainable development across all sectors to reduce environmental degradation, reverse the loss of environmental resources, and significantly reduce the rate of biodiversity loss.

Ecosystems Manager at the National Environment and Planning Agency (NEPA) Andrea Donaldson told IPS that while the agency’s work on biodiversity is not focused on climate change, they are aware of the likely impacts and continue to implement measures to safeguard the local biological diversity.

The National MDG Report has pointed to the country’s failures in efforts at pollution controls and the protection of critical ecosystems, and it is these factors that worry scientists the most.

In addition, human activities that result in deforestation, destruction of wetlands and coastal ecosystems, urban sprawl as well as disregard for the natural environment have been identified as some of the most serious threats to biodiversity.

In fact, experts are concerned that disregard for the natural environment could exacerbate the impacts of severe weather. Both the 2010 State of the Environment Report (SOE) and the National Report to the United Nations Framework Convention on Climate Change (UNFCCC) pointed to human activities as significant threats.

“Climate change is likely to further increase the negative impacts” of habitat loss, over-exploitation, poor land use and ignorance about the value of natural resources, the SOE reported.

Some experts are already describing changes in coral reefs, forests and coastal wetlands, areas that have been identified as most vulnerable to climate change. It is widely believed that with more than 12 extreme weather events in the last five years, Jamaica is already feeling the effects.

This is the most bio-endemic island in the region. Ranking fifth amongst islands of the world for the number of unique species, Jamaica’s biodiversity losses could be immense. There are more than 8,000 recorded species of plants and animals and more than 3,500 marine species here.

Among the island’s endemic treasures are 10 species of cacti, seven species of palms and 60 of the 240 species of orchids. There are 31 endemic species of birds, nine species of crabs, 505 species of the 514 varieties of land snails, and 33 of the 43 species of reptiles.

At least four of the 24 species of bats here are endemic; 17 of the 19 species of frogs and about 15 of the 115 species of butterflies.

Among the better-known unique species are the Tody, the Jamaican boa, the Jamaican Hutia also called the coney and the Giant Swallowtail Butterfly.

The island ranks among the International Union for the Conservation of Nature (IUCN) list of places with the highest number of at-risk mammals, due primarily to the threat to its endemic bats and the coney.

Another of the island’s endemic species, the Jamaican iguana, is on the IUCN’s Red List of endangered and threatened species. Roughly 200 of the animals survive in the shrinking limestone forests of Hillshire, several miles outside the capital Kingston.

And as the impacts of fewer but more intense rainy days, increased intensity of hurricanes, and periodic drought take their toll, socioeconomic problems are expected to increase the pressure on natural resources.

As the agency charged with safeguarding the island’s biological treasures, NEPA said it has spearheaded a number of policies, programmes and legislation to manage and prevent unauthorised exploitation.
