Man of the forest vulnerable to forest conversionCommon Name: Orang-utan (Eng & Bahasa Melayu)Kogiu (Orang Sungai language) Scientific Name: Pongo pygmaeus (Borneon orang-utan)Habitat: Lowland forests, also found in tropical, swamp and mountain forestsStatus: Endangered globally. Vulnerable in Sabah & SarawakPopulation: Estimated to be about 12,300 in Sabah & Sarawak, Malaysian Borneo.

Background

Asia’s only great ape, the orang-utan or ‘man of the forest’ is found only on the islands of Borneo and Sumatra. Globally classified as endangered due to their habitat being destroyed, fragmented and poaching, orang-utans in Malaysia (Sabah and Sarawak) are probably best classed as ‘vulnerable’. Much of their prime habitat has been converted to plantations and the rate of habitat loss has hit a very low level in recent years. There is almost no hunting of this species in Malaysia, and most of the remaining populations are found in forests that are protected or under natural forest management.Borneo is unique in that it has three distinct populations or subspecies of orang-utans:

Pongo pygmaeus pygmaeus (northwest populations)

Pongo pygmaeus morio (northeast and east populations)

Pongo pygmaeus wurmbii (southwest populations)

Orang-utans in the Malaysian states of Sabah and Sarawak occur mainly in the lowlands. In Sarawak, there are about 1,300 orang-utans, almost all in the Lanjak-Entimau Wildlife Sanctuary and Batang Ai National Park in the south next to West Kalimantan, Indonesia. In Sabah, there were five main areas of special importance with a total of 20,000 orang-utans in the mid 1980s (by WWF-Malaysia working with the Sabah Forestry Department, 1986).

By 2004, the orang-utan population in Sabah had dropped to about 11,000 individuals (by Kinabatangan Orang-utan Conservation Project working with Sabah Wildlife Department, 2003). This decline in their numbers in the last twenty years was caused by planned conversion of forests to plantations in the eastern lowlands. Physical and species description Orang-utans generally have brown and rust-coloured shaggy fur. Weighing in at an average of 50 kg, female orang-utans grow to about 1.1 m in height and weigh 30 - 50 kg. Males weigh 50-90 kg and stand 1.2 - 1.5 m tall.

Ecology, Habitat & Distribution

Fruit eater sleeps in new nest every nightImagine sleeping 2 storeys and above up in the trees every night. The arboreal orang-utan lives up in trees where they bend twigs and small branches together to make a large nest-platform for sleeping. They are the largest tree dwelling mammal in the world. Adult orang-utans are solitary, except during mating. Orang-utans are not territorial, maintaining a loose relationship in a given area although adult males are hostile to one another. Crowding may cause them to fight over the limited supply of fruits. An adult female gives birth about once every six years.DietOmnivorous, orang-utans eat both plants and animals but feed mainly on fruits, young leaves, bark and insects. By about the age of ten, an orang-utan can recognise over 200 different food plants. The orang-utan’s favourite food is fruit.Population decline of 40% in last two decadesOrang-utans in Sabah and Sarawak live mainly in lowland rainforests but are also found in tropical, swamp and mountain forests. Sarawak has about 1,300 orang-utans, almost all in the Lanjak-Entimau Wildlife Sanctuary and Batang Ai National Park to the south bordering West Kalimantan, Indonesia. In Sabah, there are about 11,000 individuals today, the population having declined by over 40% in the last 20 years due mainly to planned conversion of forests to plantations in the eastern lowlands. Drought and forest fires, especially during the El Nino events of 1982-83 and 1997-98, but also 1987 and 1991, contributed to the decline.

Threats

Destruction of natural forests and unreliable food sourcesWild orang-utan populations need a reliable source of a variety of fruits and young leaves to survive. They can survive only in extensive natural forests. The availability of food all year round means not all forests can support long-term breeding populations. We now know that this gentle ape can survive only in lowlands - where fertile soils and constant water availability allow steady food production - or where there are several forest types with different fruiting and leaf-producing seasons. There is little point in putting orang-utans where they have historically not existed, as lack of food supply may eventually cause them to die. There are six areas in Malaysia with quite large populations but this does not mean that any one of these places is unimportant. There is always the risk that one or more populations could be devastated by disease, drought or fires.

Maintaining natural forests with viable wild breeding populations and restoring degraded forests is vital for the continued survival of orang-utans in Malaysia. Hence, the Sabah government’s initiative to retain the largest orang-utan population in the Ulu Segama-Malua Forest Reserves under sustainable forest management (SFM) deserves full support. The Deramakot forest management model, which produces controlled amounts of timber for international auction, certified according to international standards since 1997, shows what can be done. SFM could reduce forest damage and provide enough time for the forest to regenerate. In SFM, reforestation is necessary to ensure the forest rehabilitation or restoration take place in any sustainably managed forest. In the Lower Kinabatangan, various isolated forest patches need to be joined through restoration.

Mangroves - making it right

The need to preserve the country’s remaining tracts of swamps and to reforest eroded coastlines has never been more pressing than after the tsunami. This plot in Sg Hj Doranim, Sg Besar, Selangor, is where FRIM tries to find the best way to plant mangroves.

THERE'S something riveting about a budding patch of green rising up from a bed of mire.
The tenacity in which those seedlings try to break loose from the deluge of mud, its shoots reaching up for air and life, is a sign of revitalised hope. Like a spark of life amid the murk.But by the end of a year, for every one that survives, six fail to last out the harsh elements.T

he survival rate of replanted mangroves is dismal to say the least, says expert Dr Shamsudin Ibrahim.For years, the country's foresters and many green groups and firms have spent endless hours and millions of ringgit rehabilitating mangrove forests the usual way, which is to lodge the seedling into a hole in the swamp and tie it to a stick for support.

Unfortunately, the young plant is no match for waves, wind and bad sediment.The sleepy, scenic fishing village of Sg Hj Dorani, Sg Besar, Selangor is one example. Mud along the coast is so soft that no trees would grow.

"During high tides, the mud moves. If you plant it here, the next day, the plant moves elsewhere.

"There's no chance for the seedling to establish itself," says Shamsudin, forestry and environmental director of the Forest Research Institute Malaysia (FRIM).How can delicate saplings rise above towering crashes of waves, strong winds and liquid mud to anchor themselves firm enough into the ground and grow then?

This is where the challenge is for FRIM, tasked under a national initiative to find the best way to plant mangroves.

FRIM chose the worst place to start -- the 120km-from-town Sg Hj Dorani -- where erosion is so bad it is listed as risk 1, imminently threatening properties and economic activities nearby.Mangroves stretching 1km out into the sea half a decade ago are now a mere 200m strip left holding up the Kuala Bernam forest reserve.

But Dr Raja Barizan Raja Sulaiman, project leader for the innovative planting technique component, found that the answer lies in a little intervention and creative planting methods.The Department of Irrigation and Drainage used RM1 million to build four geotubes, each a giant sack stuffed with sand and water, to break the waves in front of the 2ha study plot.More than 5,000 seedlings were then planted with the help of fishermen using the conventional method and three other innovative ways -- the comp-pillow, comp-mat and bamboo encasement methods.During low tides, the team waded gingerly into the thigh-high slush to sow the seedlings in. To reach plots further out, they glided across the mud in wooden boxes called tongkah.

One and a half years on, the backbreaking efforts paid off. Today, row upon row of apple green stalks dot the otherwise sombre mudflat.Not all seedlings rose to the occasion though. Some are playing catch-up while others washed away.Those which survived progressed well under comp-mat, especially the two Rhizophora species -- bakau kurap and minyak -- with a survival rate of over 70 per cent.Seedlings are protected in a coated wire mesh filled with loose coconut fibre and mud.

Within three weeks of being lodged soundly into the mud, roots develop and bind themselves to the cage for support.Comparatively, only a quarter survived under conventional planting."Anything less than half the survival rate is not successful," says Raja Barizan, adding that FRIM is applying for intellectual property rights over the invention.

As for the api-api or Avicennia alba, it thrives best under comp-pillow, where the seedling nestles in compressed coconut fibre held together by nylon strings. Its pencil roots are free to spread out and anchor themselves to the ground.The five-year research may still be in its early days, but both Shamsudin and Raja Barizan are confident of the outcome.

The two successful methods are being applied in Perlis, Kedah and Penang. FRIM has also been invited to rehabilitate degraded forests in Pulau Bintan, Indonesia and Singapore.Mangroves have made their lack of presence truly felt.

Global warming to blame?

The weatherman apparently doesn’t think so … at least not yet. What we are experiencing now is the normal temperature of the Southwest Monsoon during the dry season.

THE Sahara-like weather these past months has many people here pointing the finger at global warming.
At times, going out of doors seems like stepping into a furnace. While the searing heat can be unbearable, even for people used to equatorial climate like us, the thermometres have not indicated anything out of the ordinary.
The readings hover between 30 and 32 degrees Celsius — which is normal during the dry spell. The temperature gets higher when rain is scarce such as during the hot season now.
Commented Metrological Department director Wong Teck Kiong: “The weather is hot but not unnaturally hot. What we are experiencing now is the normal temperature of the Southwest Monsoon during the dry season.”
He does not blame global warming solely for the hot weather, saying the highest temperature recorded to date is 36 degree Celsius (on June 2) and the coming days may see lower temperatures with expected isolated showers.
“July and August represent the peak of the Southwest Monsoon. Of course, we can expect hotter weather after that if there is still no rain.”
In fact, rainfall is expected to drop in the coming months because the early part of the year saw more than its share of downpours.
“That’s the trend — when there’s more rainfall in the beginning of the year, it will be considerably less at mid-year,” Wong explained.
Regardless, he and his team are fully prepared for the worst case scenario such as a long dry spell and the return of the haze.
“We and the related authorities like the Royal Malaysian Air Force are ready to act,” he said, referring to cloud seeding.
Meanwhile, conservationist-environmentalist, Rebecca D’ruz asked: “Can we put the blame for this (scorching weather) entirely on global warming? I don’t know, and I can’t think of a single person who could answer that question with any degree of confidence. The bottom-line is we can only guess at what the ‘real’ impact of global warming will be, and how it will affect the daily lives of people in Sarawak.”
According to her, global warming is everybody’s favourite villain these days.
“People blame it for everything — from rising temperatures to increased floodings and incidence of forest fires. There are even those in Norway who are blaming moose flatulence on global warming.”
She acknowledged though that climate change was happening much faster than previously predicted by the world’s best minds and this is due to human activities.
Sarawak has an equatorial climate that sees daily temperatures ranging from 23 degrees Celsius in the early morning to 32 degrees during the day.
However, D’Cruz pointed out that in the past week, her thermometer at home showed a noon temperature of between 38 and 39 degrees Celsius.
In Malaysia, forecasts on climate modeling have been made with 14 GCM’s (Global Climate Models) which show Malaysia could experience temperature changes from 0.7 to 2.6 degree Celsius and precipitation changes between minus 30 and plus 30 per cent, according to ‘Climate Change — its effects on the agricultural sector in Malaysia’ by Mustafa Kamal Baharuddin, director, Soil Resource Management and Conservation Division, Department of Agriculture.
“The predicted temperature rise is cause for concern but what is equally, if not more alarming, is the 60 per cent variation in precipitation which, in Sarawak, comes largely from rainfall. It means we could experience either 30 per cent less rain or 30 per cent more rain than we are used to,” D’Cruz noted.
In an earlier interview, Wong said global warming and climate change had impacted weather patterns worldwide, Malaysia included, though in varying degrees of intensity and severity.
“Overall, long-term climate trends do not exhibit such drastic and extreme changes as evidenced by short-term climate and weather events both in terms of intensity and frequency like heavy rain episodes and high temperature with long dry spell. However, further detailed studies need to be carried out to ascertain and evaluate its impact,” he added.
Wong said in a tropical country like Malaysia, the immediate effect could be seen in the amount of rainfall.
Last year’s increased rainfall and rainy days over the annual average indicated that Sarawak had felt the effect of global warming and climate change, he noted.
Dr Pengguang Manggil, controller of Environment Quality, Natural Resources & Environment Board, believes the rising temperature is due to climactic changes caused by global warming.
“Global warming is coming and is here to stay earlier than anticipated. This phenomenon will have serious impacts on humankind if nothing is done to halt or reverse the trend,” he said.
Environment and Public Health Minister, Dato Sri Wong Soon Koh, also believes global warming is the cause of rising temperatures, currently being experienced.
“Now you can see the icebergs and glaciers melting in the North Pole.”
He added that Sarawak was now experiencing the effects of climate change though less in intensity, at least for now.
The recent floodings in Johor and Sarawak, and the typhoon-like winds and storms were tell-tale signs of the on-set of global warming, he pointed out.
A prominent scientist has warned that the tropics is expanding polewards with far-reaching impacts, notably in intensifying water scarcity in the Mediterranean, the US sunbelt, Southern Africa and Southern Australia.
Just what is global warming or climate change?
Unheard of some 30 years ago, this phenomenon has become a ‘hot’ topic and world leaders are making it a priority alongside other pressing issues like the global economic crisis and the Middle East conflict.
Explained Dr Pengguang: “Global warming, in layman’s term, is the increase in the average temperature of the Earth’s near-surface, air and oceans since the mid 20th century and its projected continuation.”
During the last 100 years (ending 2005), the global surface temperature had increased by 0.74+0.18 degrees Celsius, attributed mainly to the increase in anthropogenic greenhouse gas concentrations such as carbon dioxide, methane and ozone.
These gases in the stratosphere act like a greenhouse roof, letting in enough of the sun’s heat to keep the Earth warm for humans, plants and animals to live.
Human activities over the one hundred years have greatly increased the concentration of these gases, causing the atmosphere to hold in too much heat.
Based on the climate model projections, the global surface temperature will likely increase by a further 1.1 to 6.4 degrees Celsius in the 21st century.
In essence, global warming is caused by the increase in the concentration of anthrogenic greenhouse gases of which carbon dioxide (CO2) is the most significant.
The CO2 is released when coal, oil, gasoline, natural gas and other fossil fuels are burnt to produce electricity, heat and cool buildings and power vehicles.
The concentration of CO2 in the atmosphere has increased exponentially from 280 parts per million (ppm) at the beginning of the Industrial Revolution in Europe to about 390 ppm today, and the figure is rising to 1.5 to 2 ppm annually.
The Inter-governmental panel on Climate Change (IPCC) Special Report on Emissions Scenarios gives a wide range of future CO2 scenarios ranging from 541 to 970 ppm by the year 2100.
Reputable scientists say the CO2 concentration must be kept below 450 ppm otherwise the costs of adapting to a warmer world would not be bearable.
The other greenhouse gas is methane, released to the atmosphere when wastes in landfill, plants and other biomass decompose.
The increase in the concentration of the GHGs is also caused by land use and land use change and clearing of green areas.
Climate change, on the other hand, is the long-term significant change in the expected average weather patterns of a specific region or more relevantly to contemporary socio-political concerns of the Earth as a whole over an appropriately significant period of time.


Climate change will affect food production

AGRICULTURE is one of the sectors that could potentially be greatly affected by extreme climate change.
Physical damage, loss of harvest and drop in productivity are examples of direct and indirect effects of the phenomenon.
According to official projections, increases in temperature and changes in rainfall pattern could directly affect yields and hasten the spread of fungi and diseases.
States most vulnerable to these changes are northern peninsular Malaysia as well as coastal Sabah and Sarawak, according to ‘Climate change — its effects on the agricultural sector in Malaysia’ by Mustafa Kamal Baharuddin, director, Soil Resource Management and Conservation Division, Department of Agriculture.
The past records of Malaysia’s climate show a similar trend that has been encountered globally as indicated in assessments of the Inter-governmental panel on climate Change (IPCC).
The country’s temperature has increased 0.18 degree Celsius per decade for over 40 years since 1951.
The climate conditions are projected to continue on an upward trend. Modeling results estimate that temperature in Malaysia may become warmer by mid and end of the century. A substantial increase in monthly rainfall over the north east coastal region and decrease in monthly rainfall in west coast of peninsular Malaysia may be expected.
Future river flows in several watersheds in the east coast of peninsular Malaysia are simulated as increases in hydrologic extremes when compared with their historical levels.
By end of the century, a more significant change in the annual rainfall may be expected in the western regions of Sabah and Sarawak.
Every 10C temperature rise may cause 10 per cent reduction in rice yields and prolonged drought conditions may adversely impact the current flooded rice ecosystem, putting national food security at greater risk.
The oil palm plantation may be negatively affected in two scenarios — temperature rise that causes drought or increased rainfall that leads to flooding.
The increase in flood intensity and frequency will incur additional costs on water resources management due to the needs to adjust future flood mitigation plans as well as the existing flood mitigation schemes and drainage systems.
The rise in sea level will lead to tidal inundation, shoreline erosion, increased wave action and saline intrusion, causing submergence of corals, loss of fisheries resources, plantation lands, and mangrove forests, and possible relocation of coastal infrastructure.

Even now, climate change is already affecting hundreds of millions of people and in the next 20 years, those affected will likely more than double, making it the greatest emerging humanitarian challenge of our time.
However, many consider it is a wholly environmental problem, a view reinforced by pictures of glaciers and polar bears, not human beings.
Furthermore, even if the international community is able to contain climate change, over the next decade, human society must prepare for more severe climate change and more dangerous human impacts.
Recent evidence suggests that important changes in climate are likely to occur more rapidly and be more severe than the IPCC assessments.
In many key areas, the climate system is already moving beyond its traditional patterns.
Large-scale tipping point events such as the rapid melting of the Greenland ice sheets and the shutdown of the Gulf Stream have occurred and some have already happened such as the loss of the Arctic summer ice in 2007 and the devastating forest fires in Borneo, which may be a combined effect of deforestation and climate change.
According to Rebecca D’ruz, dire consequences await if inactivity remains on the part of mankind.
“Global warming will pass the widely acknowledged danger level of two degrees, since there is an about 20-year delay between emission reductions and the halting of their warming effect.
“This report clearly demonstrates that climate change is already highly dangerous at well below one degree of warming. Two degrees would be catastrophic.”
However, she believes now is not too late to start the reversing process as the chance to hold global warming at a 2-degree Celsius increase is still here but the race between climactic changes and climate policy will be a close one.
Added Dr Pengguang Manggil: “Environmental prediction is everyone’s responsibility because whatever each individual does will have some impact on environmental quality, be it the air, water or soil media.
“The local authorities, being the captains of the community in each municipality, have a very important role to play in that they act as the drivers of change and at the same time, as agents of the government to initiate and implement the policy framework that could well have serious impacts on our environmental quality.”

Anak paus mati tercekik sampah

Ikan paus malang kembali terdampar setelah cuba diselamatkan kakitangan Jabatan Perikanan, nelayan dan pihak bomba

PENEMUAN seekor anak ikan paus betina spesies Bryde's Whale yang terdampar di beting pasir Kuala Nenasi, Pekan, baru-baru ini menggemparkan semua pihak kerana mamalia berkenaan dianggap asing di negara ini.

Mamalia berwarna hitam dengan ukuran kira-kira 10 meter panjang dan berat lebih tiga tan metrik itu, dipercayai tersesat sebelum ditemui seorang nelayan. Ikan paus berkenaan mengalami kecederaan pada bahagian muncung dan badan dipercayai tersesat daripada kumpulan antara dua hingga tiga ekor.

Nelayan, Saman Muhamad, 42, yang menemui ikan paus berkenaan berkata, dia terkejut melihat satu objek besar terdampar pada beting pasir kira-kira 7.30 pagi ketika hendak turun ke laut. "Saya sangkakan kayu balak berwarna hitam yang hanyut, tetapi sebaik mendekatinya, saya dapati ikan paus itu masih bernyawa.

"Ketika ditemui, paras air sungai hanya setakat sirip ikan berkenaan tetapi disebabkan saiznya yang besar, ikan itu tidak mampu bergerak ke laut," katanya.

Katanya, ketika ditemui ikan paus itu masih kuat apabila sentiasa cuba berenang dan bergerak menggunakan ekornya, tetapi disebabkan air cetek di kawasan berkenaan, mamalia itu tidak mampu bergerak.

Saman berkata, dia bersama lebih 15 nelayan dibantu anggota Jabatan Bomba dan Penyelamat Pekan dan kakitangan Jabatan Perikanan Daerah berjaya menolak ikan paus berkenaan ke laut pada kira-kira jam 11 malam. Bagaimanapun, mamalia berkenaan sekali lagi ditemui terdampar di atas pasir di Kuala Nenasi dan mati ketika operasi menyelamat dilakukan.

Pegawai Penyelidik Pusat Penyu dan Ekosistem Marin (Tumec) di Rantau Abang, Terengganu, Mohd Lazim Mohd Saif pula berkata, siasatan awal punca kematian mendapati saluran usus ikan paus berkenaan tersumbat.

Katanya, plastik sampah, segumpal tali nylon dan penutup botol ditemui dalam usus mamalia berkenaan yang dipercayai menyumbat saluran ususnya.

"Ikan paus itu mengalami masalah kesihatan agak serius menyebabkan ia lemah dan tidak dapat berenang ke laut walaupun selepas operasi menyelamat dilakukan.

"Ia kembali semula ke Kuala Nenasi selepas dibawa arus deras air pasang sebelum ditemui terdampar di pantai," katanya. Beliau berkata, ikan paus itu tidak dapat membezakan antara hidupan laut dengan plastik sehingga menyebabkannya memakan bahan buangan itu.

Selain ikan paus, kes hidupan laut makan plastik yang dibuang pihak tidak bertanggungjawab turut dilaporkan berlaku kepada haiwan laut lain seperti penyu dan dugong. Mohd Lazim berkata, kecederaan pada bahagian muncung ikan paus berkenaan dipercayai terlanggar batu karang terutama selepas terpisah daripada kumpulannya akibat tersesat.

Katanya, dia bersama empat pegawai Makmal Veterinar Kuantan melakukan pembedahan selain mengambil contoh beberapa bahagian ikan paus berkenaan untuk tujuan analisis.

Mamalia berkenaan ditanam di kawasan pantai Kuala Nenasi dengan diawasi polis Nenasi dan penduduk setempat bagi mengelak berlakunya kecurian. Katanya, selepas dua bulan ditanam, Tumec akan mengambil rangka ikan paus berkenaan untuk kajian selain untuk pameran.

Angkara manusia

Usaha menyelamat Ikan paus yang ditemui terdampar di beting pasir di Kampung Kuala Nenasi, Pekan dilakukan oleh penduduk gagal, apabila ikan tersebut mati akibat terdapatnya plastik, tali dan pelbagai bahan buangan di dalam perut ikan paus tersebut setelah dibedah siasat.
Habitat laut kian terancam Persepsi tidak tepat terhadap laut menyebabkan ia menjadi tempat semua longgokan sampah dan sisa lain termasuk pembuangan minyak

MASALAH pembuangan sampah ke dalam laut sama ada akibat aktiviti yang dijalankan di kawasan marin atau di darat jika tidak ditangani segera boleh menjadi semakin serius dan berkemungkinan membawa kerosakan kepada sistem ekosistem batu karang dan laut di negara ini.

Jabatan Taman Laut, Kementerian Sumber Asli dan Alam Sekitar menjangkakan lebih banyak spesies akan mati jika isu pencemaran dan pembuangan sisa pepejal dalam laut tidak diatasi dengan segera.

Ketika ini, Malaysia mempunyai 42 peratus daripada 2,300 terumbu karang yang sihat dan 56 peratus lagi dalam kategori sederhana sihat.

Namun, kini, 20 peratus daripada 42 peratus terumbu karang yang sihat itu dicemari oleh pelbagai pencemaran seperti minyak dan sisa pepejal (pukat hanyut dan puntung rokok) yang dibuang di darat dan laut.

Jabatan itu menegaskan apabila terumbu karang mati maka ekosistem di sekelilingnya juga terancam dan berkemungkinan akan menghasilkan hasil laut yang tidak bermutu atau wujud kepupusan bagi sesetengah spesies.

Pensyarah Jabatan Pengurusan Alam Sekitar, Universiti Putra Malaysia (UPM), Prof Madya Dr Zelina Zaiton Ibrahim, berkata kesedaran awam mengenai pembuangan sisa pepejal di laut masih rendah walaupun kebanyakan faham kepentingan menjaga alam sekitar.

Ini berlaku kerana ramai yang tidak nampak kepentingan laut kepada manusia, lebih-lebih lagi laut itu dilihat luas dan jauh daripada pandangan mereka. “Kebanyakan masyarakat menganggap laut luas dan jauh daripada kehidupan harian, maka laut itu boleh menjadi tempat pembuangan sampah yang paling sesuai.

Tanggapan ini perlu diubah, jika tidak, dikhuatiri pada masa depan kawasan tadahan air akan tercemar,” katanya.

Persepsi tidak tepat terhadap laut juga menyebabkan ia menjadi tempat semua longgokan sampah dan sisa lain termasuk pembuangan minyak. Dalam kes hidupan laut mati akibat pencemaran air memang banyak dilaporkan, namun dalam kes paus tersesat dan terdampar di perairan negara ini di Kampung Kuala Nenasi, Pekan baru-baru ini, jarang berlaku.

Dilaporkan ikan itu mati kerana tercekik plastik dan tali nilon tetapi ada kemungkinan ikan berkenaan sebenarnya memang sakit akibat kualiti air yang rendah berbeza dengan habitat sebenarnya. Dr Zelina Zaiton juga menyatakan saintis percaya apabila paus sesat atau dijumpai terdampar di perairan yang bukan habitatnya menunjukkan kualiti air rendah dan pergerakan arus sudah berubah.

“Ikan paus biasanya tinggal di kawasan laut dalam dan dalam kes ini, kemungkinan ia sesat apabila arus air berubah akibat perubahan iklim dunia,” katanya. Pensyarah Pengurusan Strategik Zon Pantai dan Maritim, Jabatan Pengurusan Alam Sekitar UPM, Laksamana Pertama (B) Prof Madya Dr Sutarji Kasmin, berkata sisa buangan enap cemar juga berisiko tinggi menyebabkan pencemaran kepada hidupan laut.

Kebiasaannya, sisa buangan enap cemar seperti minyak hitam dibuang oleh kapal dagang.

Kawasan yang sering menerima akibat ini adalah laluan kapal dagang dan pelabuhan. Di negara ini, laluan yang sering menjadi tempat pembuangan enap cemar adalah Selat Melaka kerana ia adalah laluan paling sibuk di dunia. Mengikut maklumat Pusat Penyelaras Penguat Kuasa Maritim Kebangsaan, Bahagian Keselamatan Negara (BKN), Jabatan Perdana Menteri (JPM), sebanyak 144 kes pencemaran minyak laut dikenal pasti.

Daripada jumlah itu, 108 kes membabitkan pembuangan enap cemar dan 32 kapal didakwa di mahkamah tetapi hanya 14 saja didapati bersalah. Difahamkan 15 pelabuhan yang ada di Malaysia menyediakan perkhidmatan kepada kapal dagangan membuang sisa minyak seperti minyak hitam, namun kos pembersihan yang dikenakan terlalu mahal yang memaksa kapal mengambil tindakan membuang sisa berkenaan di dalam laut secara haram.

Mengikut laporan Badan Penyelaras Laut Asia Timur (Cobsea), mendapati ada dua penyebab utama pembuangan sampah di laut di negara ini iaitu sisa buangan daripada kapal dan aktiviti di darat. Pembuangan sampah daripada kapal ini berlaku akibat aktiviti yang dilakukan di laut.

Selain kapal dagang dan bot menangkap ikan, pelabuhan dan loji minyak turut menyumbang kepada pencemaran dan pembuangan sisa pepejal dan cecair ke laut.

Sisa buangan daripada jeti minyak dan gas serta bahan buangan daripada kapal nelayan, bot rekreasi dan kegiatan memancing turut menyumbang kepada pembuangan sampah ke laut. Setakat ini, Malaysia mempunyai 15 pelabuhan yang menyediakan kemudahan pembuangan sampah sarap daripada kapal yang mana sampah itu diuruskan oleh kontraktor yang dilantik mengendalikannya.

Aktiviti di daratan turut menyebabkan pencemaran laut terutama kawasan persisiran pantai atau pulau seperti Pulau Pinang dan Langkawi. Sampah sarap daripada daratan dibawa ke laut melalui sungai dan terusan yang turut memberi kesan kemusnahan kepada pantai. Kegiatan pelancongan dan rekreasi di sepanjang pantai peranginan menjadi antara penyumbang pembuangan sampah.

Begitu juga pengurusan sampah di daratan yang tidak teratur turut menyebabkan ia mencemari laut. Pembuangan sampah biasanya datang daripada kawasan perumahan, rekreasi, kemudahan awam, pusat komersial, kawasan industri, tempat pembuangan sampah dan aktiviti pertanian.

Maka, perlu ada amalan yang baik untuk pengurusan sampah dan cara pengendaliannya (pengumpulan, penghantaran, pengangkutan dan pengalihan, penghapusan dan penembusan sampah). Pada masa ini, mengikut laporan itu, pengurusan sampah di Malaysia dijalankan pihak berkuasa tempatan (PBT).

Kini Malaysia menyediakan Pelan Strategi Kebangsaan Pengurusan Sisa Pepejal yang mensasarkan mengurangkan sumber dan mencegah pembuangan sisa pepejal; mempelbagaikan lagi sistem pengurusan sampah menerusi kaedah kitar semula dan penggunaan semula, penukaran teknologi dan pengenalan kemudahan pembuangan sampah seperti insinerator dan sampah sebagai sumber tenaga baru.

Di Malaysia, kerja pembersihan sampah di pantai dilakukan kumpulan badan bukan kerajaan (NGO), PBT, pertubuhan berkaitan marin dan pusat peranginan pantai termasuk hotel.

Cobsea mencadangkan Malaysia meningkatkan lagi aktiviti pembersihan pantai dan meningkatkan lagi kesedaran awam kepentingan menjaga alam sekitar selain mengurus dengan baik pembuangan sisa ke laut. Ketiadaan data lengkap mengenai tahap kebersihan dan pencemaran menyukarkan usaha mengatasi masalah pembuangan sampah di Malaysia.

Namun, secara keseluruhannya warga Malaysia sudah ada kesedaran mengenai masalah pembuangan sampah melalui siri kempen pembersihan pantai dan program kesedaran yang dilakukan berterusan.

Ozone hole 'larger in 2008 than previous year'

GENEVA (AFP) - - The ozone hole is larger in 2008 than the previous year but is not expected to reach the size seen two years ago, the World Meteorological Organisation said Tuesday.

"In 2008, the ozone hole appeared relatively late. However, during the last couple of weeks it has grown rapidly and has now passed the maximum size attained in 2007," the WMO said in a statement.

The hole in the layer over the Antarctic was discovered in the 1980s. It regularly tends to form in August, reaching its maximum size late September or early October before it fills again in mid-December.

The size it reaches is dependent on weather conditions.

Experts warned that such is the damage to the ozone layer, which shields the Earth from harmful ultra-violet rays, it will only attain full recovery in 2075.

"It would take decades for the hole to disappear and for it to return to the situation before 1980.

We are looking at 2075," Geir Braathen, who is the World Meteorological Organisation's expert on the subject told AFP.

On September 13, the hole covered an area of 27 million square kilometers, while in 2007, the maximum reached was 25 million square kilometers, said the WMO.

"Since the ozone hole is still growing, it is too early to determine how large this year's ozone hole will be," it added.

Ozone provides a natural protective filter against harmful ultra-violet rays from the sun, which can cause sunburn, cataracts and skin cancer and damage vegetation.

Its depletion is caused by extreme cold temperatures at high altitude and a particular type of pollution, from chemicals often used in refrigeration, some plastic foams, or aerosol sprays, which have accumulated in the atmosphere.

Most of these chemicals, chlorofluorocarbons (CFCs), are being phased out under the 1987 Montreal Protocol, but they linger in the atmosphere for many years.

Hundreds of Borneo aborigines forced from their homes

KUALA LUMPUR: The authorities have forcibly evicted hundreds of families from villages in the Bintulu district of Sarawak in Borneo in the past year, claims Sahabat Alam Malaysia.

Sahabat Alam Malaysia council member Mohideen Abdul Kader said the Forest Department and Land and Survey Department had issued licences to convert the land and forests in the area to plantations without obtaining the consent of the communities who have native customary rights (NCR).

Glyn Ingang, 32, from Kampung Mejau in Tatau, said they were only offered compensation of RM250 per hectare and had not agreed to give up their land.

“There are 80 families in my village, and the concessionaires or the contractors just come in like that to demolish our longhouses and evict us.

“My ancestors have been staying here for hundreds of years, long before Malaysia was even formed,” he said.

Bagong Swee, 49, from Kampung Sebungan in Sebauk, said the rubber trees which were cultivated by the locals were chopped down by workers, leaving them with no source of income.

“They even polluted our river, and we can’t even use it to bathe as our skin will get itchy. Now, we only drink rain water,” he said, adding that more than 250 families were affected.

Bagong said the concessionaires had started an oil palm plantation on the land, and he said the villagers might have to resort to ‘harvesting’ their oil palm and selling them to survive.

Marai Sengok, 27, from Kampung Binyo, said besides tearing down their longhouses and food storage huts, the workers had also destroyed their crops with pesticides.

“We can only stand and watch as they tear down our homes, as they are always accompanied by armed policemen,” he said.

At a press conference here on Wednesday, Mohideen called for a Commission of Inquiry to be set up to probe into the logging and plantation industry in Sarawak.

“Sarawak must accord full recognition on the NCR - both on cultivated and forest areas. The enroachment of NCR land must be put to a stop,” he said.

He said it was disturbing that Sarawak Forest Department itself is the project proponent for one of the projects, involving 490,000ha of land.

He claimed the department had licensed out 2.8mil ha of largely forest land for 40 plantation concessions, mainly for oil palm and pulpwood trees, since 1997.
