Abstract :

Bamboo forests are important ecosystems from various ecological aspects in the world, especially in Japan, and account for about 3.2% of the total forest area in the world. Bamboos have not only economic values brought by many different uses but also the ecological function for environmental conservation. Among environmental problems, a major problem facing this world is global warming. Bamboos are known to have the comparatively fast growth rates in the world so do their absorption and stock of CO2 has the potential to mitigate global warming. The aim of this study was to determine the potency of carbon stock in the abandoned bamboo forest stand consisting of Phyllostachys nigra Munro var. Henonis Stapt. with the analysis of the stand dynamics. P.nigra has monopodial rhizomes and almost every part of this bamboo is usable. The field survey was conducted in a P.nigra stands, which is located in urban fringes of Okayama city, the western Japan (34°43’ N, 133°56’E) and is adjacent to a secondary deciduous broad-leaved forest in the outer part. We used long-term data that was obtained from 1993 to 2009 in a 10mx40m permanent plot, which was divided into inner and outer plot in the analysis. This study only covers the above ground organs, i.e., culms, branches and leaves. Biomass (B) of P.nigra was estimated from allometry relations, and carbon stock (C) was calculated as follows; C=0.45*B.
This research showed that density of living culms is higher in inner plot than in outer plot. The density of living culms in outer plot has been increasing with positive and higher growth rates of culms that were calculated from the balance between mortality rates and recruitment rates of culms. As the results, the bamboo stand has expanded to an adjacent forest. On the other hand, density of living culms in inner plot tended to be more stable and the changes were smaller with low growth rates of culms. Above ground biomass of P.nigra was mostly allocated in culms. Above ground biomass and C-stock in the stand level have increased in outer plot at the rate of 1.59 ton C ha-1 yr-1. It is likely that the biomass and C-stock have attained to a stable condition in inner plot. The total C-stock in that stable condition of P.nigra stands averaged 68.2±2.9 ton C ha-1, which is likely to be similar with other forests or larger than other forests. Therefore, P.nigra stands probably possess a great capacity for carbon dioxide reduction. It is expected that C-stock in the bamboo forests will increase because the bamboo forests have been expanding. However, at the same time we must consider the management so that suitable relations to other forests can be maintained.

Global Forest Resources Assessment 2010

wahyukdephut — Thu, 17 Feb 2011 02:30:38 +0000

The Global Forest Resources Assessment 2010 (FRA 2010) is the most comprehensive assessment of forests and forestry to date – not only in terms of the number of countries and people involved - but also in terms of scope. It examines the current status and recent trends for about 90 variables covering the extent, condition, uses and values of forests and other wooded land, with the aim of assessing all benefits from forest resources. Information has been collated from 233 countries and territories for four points in time: 1990, 2000, 2005 and 2010. The results are presented according to the seven thematic elements of sustainable forest management. FAO worked closely with countries and specialists in the design and implementation of FRA 2010 – through regular contact, expert consultations, training for national correspondents and ten regional and subregional workshops. More than 900 contributors were involved, including 178 officially nominated national correspondents and their teams. The outcome is better data, a transparent reporting process and enhanced national capacity in developing countries for data analysis and reporting. The final report of FRA 2010 was published at the start of the latest biennial meeting of the FAO’ Committee on Forestry and World Forest Week, in Rome.

2 February 2011, New York/Rome – Millions of forest-dependant people play a vital role in managing, conserving, and developing the world’s forests in a sustainable manner, but the outside world often underestimates their rights to use and benefit from local forest resources, says FAO’s new State of the World’s Forests report, launched at the opening ceremony of the United Nations International Year of Forests in New York today.

Kebakaran Hutan dan Lahan Gambut

wahyukdephut — Sun, 13 Feb 2011 16:22:45 +0000

Kebakaran di lahan gambut secara lamban tapi pasti akan menggerogoti materi organik di bawahnya dan gas-gas yang diemisikan dari hasil pembakaran dapat memberikan kontribusi terhadap perubahan iklim global. Tahun 1997, kebakaran lahan gambut di Sumatera dan Kalimantan telah menjadi berita utama dimana-mana. Pihak Malaysia dan Singapura sangat khawatir akan dampak kebakaran yang ditimbulkan terhadap kesehatan warganya. Estimasi luas dan dampak kebakaran yang terjadi pada tahun 1997/1998 telah dilakukan oleh beberapa pihak, meskipun tidak terdapat kesamaan dalam hasil estimasi, tetapi menunjukkan bahwa rawa gambut yang terbakar di Indonesia pada 1997/1998 melebihi 1 juta hektar. Api yang terdapat di dalam lahan gambut (ground fire) sulit diketahui sebarannya,karena ia bisa saja menyebar ke tempat yang lebih dalam atau menjalar ke lokasi yang lebih jauh tanpa dapat dilihat dari permukaan. Usaha pemadaman api di lahan gambut, jika terlambat dilakukan, atau apinya telah jauh masuk ke lapisan dalam gambut, akan sulit untuk dipadamkan. Selain itu, hambatan utama yang dihadapi dalam usaha pemadaman adalah sulitnya memperoleh air di dekat lokasi kejadian dalam jumlah besar serta akses menuju lokasi kebakaran sangat berat. Oleh karena itu, pemadamanapi di lahan gambut yang kebakarannya sudah parah/meluas hanya dapat ditanggulangi secara alami oleh hujan yang deras.

Menanam dalam Keterbatasan untuk Mewujudkan Hutan Lestari (Oleh : Wahyu Catur Adinugroho)

KabarIndonesia - Selopuro, itulah nama dusun yang menjadi potret penulis. Selopuro merupakan salah satu dusun di kecamatan batuwarno, kabupaten wonogiri propinsi jawa tengah. Melihat namanya saja, orang jawa pasti sudah mengetahui bagaimana kondisi dusunnya, karena pada umumnya nama suatu dusun diambil dari sesuatu yang terjadi pada daerah tersebut atau keberadaan sesuatu yang khas pada daerah itu. Selopuro berasal dari bahasa jawa yang terdiri dari 2 kata yaitu “selo” dan “puro”. Dalam bahasa jawa, “selo” berarti batu dan “puro” dapat diartikan sebagai kerajaan sehingga selopuro dapat diartikan sebagai kerajaan batu, ya memang kondisi inilah yang ada di dusun selopuro. Hampir sebagian besar wilayah yang ada di dusun selopuro berupa areal perbukitan yang dipenuhi dengan batu-batu sehingga masyarakat memerlukan kearifan tersendiri dalam menyikapi untuk memenuhi kebutuhan hidup dari kondisi yang ada.

Ditengah maraknya upaya pemerintah untuk membangun hutan kembali dengan berbagai program seperti , GERHAN, OMOT (One Man One Tree), gerakan menanam sepuluh pohon, seratus pohon, sejuta pohon atau semilyar pohon, yang terkesan hanya “celebration” dan formalitas melaksanakan program dan anggaran. penulis melihat bahwa apa yang terjadi di Selopuro adalah suatu motivasi bagi seluruh rakyat Indonesia untuk kembali membangun hutan.

Dengan apa yang telah dirasakan sebelum terbangunnya hutan (sebelum tahun 1960-an), kesulitan mendapatkan sumber air, banjir dan longsor, kesejahteraan dan tingkat pendidikan yang sangat rendah telah mendorong warga selopuro untuk bersikap arif terhadap kondisi ekonomi dan geologis yang ada.
