Sources, Sites and Components of Greenhouse Gases (GHGs) from Animal Agriculture in West Papua Province, Indonesia. International Journal of Environmental Monitoring and Analysis. Vol. 4, No. 5, 2016, pp. 121-126. doi: 10.11648/j.ijema.20160405.11 Received: July 22, 2016; Accepted: August 5, 2016; Published: September 2, 2016 Abstract: Environmental status of an area needs to be recognized with both locally and globally measureable indicators. Papua Barat has played important roles as carbon sink of the world with its forest cover. However, recently many areas are being converted for several functions. Agricultural function is a leading sector for the environmental degradation with emissions uncounted produced. Data collected from nine regencies compiled by West Papua province environmental department were accounted for. Quantifications were made to compute average emission resulted from large livestock, small livestock and poultry-manure production. Manure and slurry were the main sources of GHGs emissions, i.e. CO 2 , CH 4 and N 2 O. The highest contribution was produced by poultry followed by large livestock and small livestock (p<0.01). In terms of poultry, broiler was the highest (p<0.05) compared to village chicken, egg poultry and duck. The three highest producing emissions are Manokwari, Kota Sorong and Sorong.

Introduction In the late two decades, greenhouse gases have been reported and questioned worldwide increasing the heat resulted in ozone depletion. Many factors had been identified causing this environmental phenomenon. Man-made products in such fields like agricultural field [3], fabrication and cars, are computed contributing on accumulated greenhouse gases (GHGs) in the ozone layer. These effects, such as acid rain and shifted local climate, are in turn resulted and experienced nowadays by many countries. In country such us Indonesia, tropical rain forest is reduced significantly for various functions. Many forests cut and land converted to various functions such as infrastructure, buildings and agriculture productions. Although there has been shifted, by the low and regulation of department of Forestry, Republic of Indonesia), in forest production and management, damaged forests in many hectares have been occurred. Tropical forest owned by Indonesia mentioned as one of the world green belt left beside Brazil with its Amazon and Zaire, Africa. The latter has been increased in use in West Papua. Oil palm plantation and land for other agricultural production, such as housed and un-housed raising livestock, have been demanded [2]. This may give positive impact on losing carbon sink and carbon sequestration in the nature. Land use conversion in West Papua has drastically changed for some agricultural functions, such as paddy field and palm plantation. Due to this, emissions resulted towards CH 4 and
