This study measures the relationship and dynamic impacts of economic growth forested area on carbon dioxide (CO2) emissions in Malaysia. Time series data over period 1990 to 2016 were used by employing ordinary least squared (DOLS) approach. The results DOLS estimation indicate that coefficient is positive significant with CO2 emissions, meaning RM1 million increase gross domestic product (GDP) associated an 0.931 kilo tons. Instead, long-run found negative significant, which implies...
Malaysia has a large extent of forest cover that plays crucial role in storing biomass carbon and enhancing sink (carbon sequestration) reducing atmospheric greenhouse gas emissions, which helps to reduce the negative impacts global climate change. This article estimates economic value stock per hectare forested area based on price removing ton CO2eq USD from 1990 2050. The stored forests is estimated at nearly 51 billion 2020 approximately 41 2050, whereas 2885 2388 If BAU scenario loss...
Global climate change has become a critical issue due to the global greenhouse gases (GHGs) emissions dominated by carbon dioxide (CO 2 ). Forest ecosystems are becoming increasingly essential in mitigating absorbing atmospheric CO and storing it tree biomass, process known as sequestration. Decades of environmental valuation research show that forest positive economic impact. Economic provides mechanism for mitigation policy instruments, compare rival forestry initiatives, infuse public...
The Intergovernmental Panel on Climate Change (2013) reported that more than half of the observed increase in global average surface temperature was caused by anthropogenic Greenhouse gas (GHG) concentrations and other forcings together. Continued emissions GHGs will cause further warming changes all components climate system. Thus, limiting change require substantial sustained reductions GHG emissions. Deforestation burning fossil fuels are major source carbon emission developing countries...
Canopy height is a fundamental parameter for determining forest ecosystem functions such as biodiversity and above-ground biomass. Previous studies examining the underlying patterns of complex relationship between canopy its environmental climatic determinants suffered from scarcity accurate measurements at large scales. NASA’s mission, Global Ecosystem Dynamic Investigation (GEDI), has provided sampled observations vertical structure near global scale since late 2018. The availability...
Penilaian semula komposisi hutan adalah penting bagi melihat status kesihatan tersebut terutamanya dalam tempoh masa tertentu. Oleh itu, satu kajian bancian selepas tiga tahun dijalankan di Hutan Bakau Taman Negara Tanjung Piai, Johor menilai pokok bakau berdiameter 5 cm dan ke atas, pada paras dada (DBH ≥ cm). Data sekunder, turut digunakan membandingkan data terkini yang lepas mencapai objektif kajian. Hasill terkini, merekodkan sejumlah 292 individu 0.12 hektar (ha) plot mana hanya famili...
Rubiaceae adalah famili terbesar dalam kumpulan dikotiledon di Semenanjung Malaysia. Suatu kajian awal berkaitan struktur dirian dan komposisi pokok daripada telah dijalankan hutan dipterokarpa tanah rendah Hutan Simpan Behrang, Perak. Tiga plot berukuran 25 m x 20 (0.05 hektar) ditubuhkan secara rawak denai terpilih. Keluasan keseluruhan 0.15 ha. Bancian melibatkan semua yang diameter pada paras dada 1.0 cm ada ke atas. Pokok ditanda manakala sampel daun dikutip, diawet sebelum dicamkan...
Komposisi hutan paya bakau terdiri daripada pokok yang mampu beradaptasi dengan persekitaran ekstrem. Hutan ini memainkan peranan penting dalam ekosistem dan merupakan sangat produktif. Ekosistem kian merosot telah mengalami perubahan ketara akibat faktor semula jadi antropogenik sejak beberapa dekad lalu. Taman Negara Tanjung Piai, Johor, diwujudkan untuk melindungi kawasan berlumpur bakau, serta menyumbang kepada keseimbangan kritikal ini. Mengetahui komposisi anak adalah mengetahui...
Kajian ini melaporkan spesies-spesies daripada genus Xerospermum yang ditemui di Taman Negara Pahang. Sejumlah dua spesies telah direkodkan iaitu X. laevigatum dan noronhianum. Kutipan terawal dibuat oleh H.N. Ridley pada 1891 bagi sekitar Sungai Tahan. Bagi noronhianum, kebanyakan kutipan tahun 1970an dibeberapa lokaliti seperti Tahan, Ulu Tembeling, Bukit Tersik Lata Berkoh. membantu mengemaskini senarai This study reports the species from found in A total of two were recorded, namely and...
Satu kajian berkaitan struktur komuniti dan dirian pokok telah dijalankan di Hutan Simpan Paya Pasir, Temerloh, Pahang. ini merupakan hutan dipterokarpa tanah rendah yang dibalak terkecil daerah Temerloh. Dua buah plot, setiap satu berukuran 20 m x dibina secara rawak. Keluasan plot adalah 0.08 hektar. Semua berdiameter pada paras dada (DBH) 5.0 cm ke atas ditanda diukur. Sampel dikutip, diawet dicamkan sehingga peringkat spesies. Sebanyak 96 individu daripada 38 spesies, 30 genus 22 famili...
Suatu tinjauan berkaitan senarai spesies daripada famili Myrtaceae telah dijalankan di hutan dipterokarpa tanah rendah dan bukit Hutan Simpan Gunung Tebu, Terengganu. Sebanyak 22 empat genus bagi direkodkan sekitar Syzygium merupakan terbesar diwakili oleh 19 takson manakala tiga lagi (Decaspermum, Rhodamnia Tristaniopsis), masing-masing satu spesies.
