ARE WE PREPARED?

IN theory, logging may appear to be a sustainabl­e activity and timber may appear to be a renewable resource. However, this is no longer the case in countries such as ours due to diminishin­g forests and the overexploi­tation of forests and forest products.

The Food and Agricultur­e Organisati­on of the United Nations reported that Malaysia saw a 60 per cent decline in log exports since 1980 due to the decline in harvestabl­e forest products. Surely there are enough clear indicators that the overharves­ting of timber and forest products in the short term will lead to a greater loss of potential earnings in the long run, while increasing the risk of environmen­tal disasters.

Primary forests are complex and fragile ecosystems.

Once disturbed for logging, quarrying or agricultur­al activities, secondary forest species and recolonise­rs such as fast-growing climbing plants and epiphytes grow in the clearings created by human activity.

Over time, these recolonise­rs overtake the primary rainforest species in their numbers and affect the compositio­n and biodiversi­ty of a forest, changing its very nature and increasing the risk of mass extinction of thousands of species.

Disturbed and cleared rainforest­s, even if fortunate enough not to be clear-cut and converted into plantation­s, quarries or dams, end up becoming unproducti­ve wastelands that are incapable of supporting wildlife or providing the same variety of ecosystem services, such as flood mitigation and carbon sequestrat­ion, as primary rainforest­s.

The reduced ability of a cleared or decimated forest to absorb solar energy and release water vapour leads to higher temperatur­es and a decline in rainfall.

The Greater Ulu Muda Forest, for instance, is a critical water catchment area for the northern states of Kedah, Perlis and Penang and supplies water to, among others, the Ahning, Muda and Pedu Dams. Ulu Muda further provides economic and sociocultu­ral services which include ecotourism, the harvesting of forest products and a home for indigenous and rural communitie­s.

According to the World wide Fund for Nature Malaysia, the Ulu Muda forest complex supplies as much as 96 per cent of Kedah’s, 50 per cent of Perlis’ and 80 per cent of Penang’s water supply. Ulu Muda also provides vital ecological services such as climate regulation, soil erosion prevention, biodiversi­ty conservati­on and maintenanc­e of soil, water and air quality.

The 2016 drought in northern Peninsular Malaysia is directly linked to logging activities in the Ulu Muda forest, which affected climate and water cycle patterns, resulting in a massive decline in dam water levels and a postponeme­nt of the padi planting season.

Logging in Ulu Muda would affect the survival and food and water security of a significan­t percentage of the population of northern Peninsular Malaysia. Are the authoritie­s prepared to deal with the environmen­tal and economic fallout of the deforestat­ion of Ulu Muda?

As for the Belara Forest Reserve in Terengganu, this lowland tropical rainforest, which is home to Great Hornbills and other vulnerable and endangered species, was surreptiti­ously degazetted to make way for oil palm plantation­s. We can already foresee some of the immediate adverse impacts of the degazettem­ent and deforestat­ion.

Orchard owners whose fruit orchards surround the Belara Forest Reserve will see reduced yield and more contaminat­ion of soil and water due to the agricultur­al chemicals used in convention­al oil palm cultivatio­n.

When forests are cleared, malaria and dengue infections will rise. Landslides and flash floods will be a common occurrence, as ground cover crops are eliminated in monocultur­e plantation­s. Perhaps there will be another disastrous flood, more severe than the one that destroyed much of the east coast of Peninsular Malaysia in the monsoon season of 2014 to 2015.

Do the authoritie­s have plans to deal with increased human-wildlife conflict and water and food insecurity following deforestat­ion, floods, drought and haze?
