“…The challenges that Peruvian peatlands face are substantially different from those in Southeast Asia. Therein Southeast Asia, peatlands are under great pressure from agricultural expansion, artificial drainage, and fires, which result in considerable GHG emissions (Gaveau et al 2014;Hergoualc'h and Verchot 2014). In contrast, anthropogenic degradation of peatland in the Peruvian Amazon is mostly related to recurrent harvesting of M. flexuosa palms from natural stands without drainage or fire.…”

Tropical peatlands in the Peruvian Amazon exhibit high densities of Mauritia flexuosa palms, which are often cut instead of being climbed for collecting their fruits. This is an important type of forest degradation in the region that could lead to changes in the structure and composition of the forest, quality and quantity of inputs to the peat, soil properties, and greenhouse gas (GHG) fluxes. We studied peat and litterfall characteristics along a forest degradation gradient that included an intact site, a moderately degraded site, and a heavily degraded site. To understand underlying factors driving GHG emissions, we examined the response of in vitro soil microbial GHG emissions to soil moisture variation, and we tested the potential of pneumatophores to conduct GHGs in situ. The soil phosphorus and carbon content and carbon-to-nitrogen ratio as well as the litterfall nitrogen content and carbon-to-nitrogen ratio were significantly affected by forest degradation. Soils from the degraded sites consistently produced more carbon dioxide (CO 2 ) than soils from the intact site during in vitro incubations. The response of CO 2 production to changes in water-filled pore space (WFPS) followed a cubic polynomial relationship with maxima at 60-70% at the three sites. Methane (CH 4 ) was produced in limited amounts and exclusively under watersaturated conditions. There was no significant response of nitrous oxide (N 2 O) emissions to WFPS variation. Lastly, the density of pneumatophore decreased drastically as the result of forest degradation and was positively correlated to in situ CH 4 emissions. We conclude that CIAT, Cali, Colombia recurrent M. flexuosa harvesting could result in a significant increase of in situ CO 2 fluxes and a simultaneous decrease in CH 4 emissions via pneumatophores. These changes might alter long-term carbon and GHG balances of the peat, and the role of these ecosystems for climate change mitigation, which stresses the need for their protection.

“…Bare peatland consistently emit higher CO 2 than under forested land. These results were supported by Warren et al (2016) and Hergoualch et al (2013) that land cover change could impact on increasing soil carbon emission. These results indicate that forest canopy, beside its roles in sequestering atmospheric carbon, can also be beneficial in reducing CO 2 respiration from peatland soil.…”

Abstract. Astiani D, Burhanuddin, Taherdjadeh M, Curran LM. 2016 8: 201-206. Peatland forest is one of ecosystems that are susceptible to the alterations of water regimes. Our previous study demonstrated that hydrologic conditions are predominant variables in determining carbon respiration rates from peat soils. However, we have limited empirical measures of how hydrologic conditions (i.e., soil water table) affect the carbon respirations. A study had been conducted to ascertain the effects of water table levels on soil CO 2 respirations of West Kalimantan coastal forested and bare peatland. We simulated natural intact peat core condition by designing 25 of "a double bucket" water level experiment using 5 levels of water tables (0-40cm) and measure soil CO 2 respiration at soil surfaces. Results showed that water table levels significantly affected soil CO 2 respiration, as well as peat microclimate conditions. Results also demonstrated that forest canopy had significant effects on reducing peat CO 2 respiration through its function in maintaining site-environment conditions compared to bare peatland site. This study reveals that it is important to maintain peatland water level close to peat surface and to maintain forest/vegetation covered on peatlands to reduce soil CO 2 emissions.

Asap kebakaran hutan dan lahan gambut dapat menjalar sehingga mengganggu sistem transportasi penerbangan, aktivitas ekonomi dan kesehatan masyarakat seperti infeksi saluran pernapasan akut (ISPA), diare dan gatal-gatal (Sumantri, 2003;Aiken, 2004;Hergoualc'h and Verchot, 2013).…”

AbstrakKeberadaan ekosistem hutan rawa gambut di Indonesia terus mengalami gangguan dan kerusakan akibat pola pemanfaatan yang tidak bijaksana seperti terjadinya kebakaran hutan dan lahan. Umumnya kebakaran tersebut berasal dari adanya kegiatan manusia seperti penggunaan dan perubahan tutupan lahan. Kawasan Lindung Hutan Rawa Gambut Semenanjung Kampar termasuk salah satu ekosistem hutan rawa gambut terbesar di Pulau Sumatera. Peranan utama dari kawasan ini sebagai penjaga kestabilan lingkungan terhadap kawasan sekitarnya. Tujuan dari penelitian ini adalah untuk mengetahui tingkat dan status serta faktor-faktor kunci yang mempengaruhi keberlanjutan pengelolaan ekosistem hutan rawa gambut terhadap kebakaran hutan dan lahan dengan menggunakan pendekatan Multi-Dimensional Scaling. Mengacu kepada hasil penelitian secara keseluruhan indeks atau status keberlanjutan berada pada kriteria sedang (45,81%) atau status cukup berkelanjutan. Secara parsial untuk masing-masing dimensi yang memiliki status cukup berkelanjutan adalah ekonomi, teknologi dan hukum, sedangkan dimensi ekologi dan sosial kurang berkelanjutan sehingga perlu mendapatkan perhatian serius.Kata kunci: gambut, kebakaran, skala, Kampar.
