“…Annual CO 2 emission reported in the current study was generally consistent with previous studies, under different climate conditions and cropping systems (Abbas, Fares, Valenzuela, & Fares, 2012; Chi et al., 2020; Lentz et al., 2014; Qi, Niu, Zhou, Jia, & Gao, 2018). Nevertheless, our results were higher than those reported by Lentz et al.…”

Land application of biochar reportedly provides many benefits, including reduced risk of nutrient transport, greenhouse gas (GHG) emission mitigation, and increased soil C storage, but additional field validation is needed. We evaluated the effectiveness of biochar in controlling the lability of nutrients in agricultural land. This study was designed to evaluate the impacts of biochar co-applied with various N and P sources on GHG fluxes from a subtropical grassland. Nutrients (inorganic fertilizer and aerobically digested Class B biosolids) were surface applied at a rate of 160 kg plant available N ha −1 yr −1 with or without biochar (applied at 20 Mg ha −1). Greenhouse gas (CO 2 , CH 4 , and N 2 O) fluxes were assessed using static chambers and varied significantly, both temporally and with treatments. Greenhouse gas fluxes ranged from 1,247 to 23,160, −0.7 to 42, and −1.4 to 376 mg m −2 d −1 for CO 2 , N 2 O, and CH 4 , respectively. Results of the 3-yr field study demonstrated strong seasonal variability associated with GHG emissions. Nutrient source had no effect on soil CO 2 and CH 4 emissions, but annual and cumulative (3-yr) N 2 O emissions increased with biosolids (8 kg N 2 O ha −1 yr −1) compared with inorganic fertilizer (5 kg N 2 O ha −1 yr −1) application. Data suggested that environmental conditions played a more important role on GHG fluxes than nutrient additions. Biochar reduced CO 2 emissions modestly (<9%) but had no effects on N 2 O and CH 4 emissions.

“…Major methodological limitations were appointed to input data availability (9 answers), expert or local knowledge (1), modeling domain (1), modeling uncertainties (6), input data uncertainties (10), temporal-spatial resolution (7), directive metrics (1), computational resources (4), pollutants (2), definition of parameters of methodology (3), coverage of station network (1) and no limitation (2). Within this study, a relevant conclusion was the possibility for examining if the similarities or discrepancies between the representativeness estimates are more or less significant according to the concentration levels measured by target station.…”

“…Environmental emissions play a key role in the release of pollutants on air, water and soil matrix, which is relevant because drives a decline of biodiversity [1]. In this sense, deforestation, water pollution, acid rain or endangered animals are factors linked to likely environmental repercussions [2,3]. In the health framework, numerous epidemiological studies associate the presence of pollutants in the environment and harmful effects on human being health [4,5].…”

An air quality monitoring network (AQMN) is a basic piece of environmental management due to that it satisfies the major role in monitoring of environment emissions, in special relevance to target air pollutants. An adequate installation would lead to support high efficiency of the network. Therefore, AQMN pre-layout should be considered as an essential factor in regarding with the location of fixed measurement stations within AQMN, as the minimum number of sampling points. Nevertheless, once AQMN has been already installed, and given that the spatial air pollutants pattern can vary along time, an assessment of the AQMN design would be addressed in order to identify the presence of potential redundant fixed monitoring stations. This approach would let to improve the AQMN performance, reduce maintenance costs of the network and consolidate the investment on those more efficient fixed stations. The chapter includes aspects relative to air pollutants measured by networks, their representativeness, limitations, importance, and the future needs. It ponders the need of re-assessment of the AQMN layout for assuring (i) a right evaluation of the human being exposure to atmospheric pollutants and controlling the environmental emissions into the atmosphere and (ii) an adequate performance of the network along time.

“…Saat ini penggunaan pupuk N meningkat secara signifikan untuk meningkatkan produksi, namun tidak sedikit pula pupuk yang diberikan menjadi tidak efisien dan efektif. Pemberian pupuk N cukup signifkan dalam meningkatkan emisi CO 2 dibanding tanpa pupuk N (Chi et al, 2020;Gon et al, 2012). Lebih lanjut Li et al (2011) menjelaskan bahwa pemberian pupuk N di perkebunan kopi tanpa penaung memacu laju fluks CO 2 .…”

Coffee is a commodity that has an important role in the national economy. Currently, coffee cultivation is threatened by climate change caused by global warming due to increased green house gas (GHG) emissions. The organic plantation model is a farming model that is considered to increase soil and crop productivity, reduce GHG emissions, and increase carbon sequestration effectively. The study was aimed to estimate GHG emissions and carbon stocks in organic and conventional coffee plantations in Badung Regency, Bali Province and Laboratory in Balai Penelitian Lingkungan Pertanian, Pati, Jawa Tengah Province, in July 2018. The study was conducted in smallholder coffee plantations in Badung Regency and the analysis was carried out at Laboratory of Indonesian Agricultural Environtment Research Institute. This study used a survey method, while the sampling used a purposive sampling method in organic and conventional coffee plantation. GHG emissions measurement was carried out with a close chamber method by simultaneously the carbon stocks measurement was carried out with the non-destructive method for plant biomass and destructive for understorey. The results showed that organic and conventional coffee plantations emitted GHG by 20.71 and 39.75 ton CO2e ha-1 and stored carbon stock by 227.56 and 288.31 ton CO2e ha-1, respectively. The differences in GHG emissions and carbon stocks are partly due to differences in management system and the diversity of plant. The management system of the organic coffee plantation should be improved to support handling of the impacts of climate change in Bali Province.
