“…The GHG values of unit inputs were obtained by multiplying each input by its own emission coefficient taken from the literature (Table 3) and were reported by Mg of compost produced and by production unit (hectare) per year, for the whole cultivation cycle. The GHG emissions were divided both by category (e.g., human labor, fuels, fertilizers) and operations (e.g., sowing, tillage, fertilizers application) [27,32,40]. Aside from the CO 2 equivalent emissions measured during the crop's cultivation operations, a further direct and indirect GHG impact of fertilizers use, and plants biomass decomposition arises from N 2 O emissions from soils.…”

“…These methods are material flow analysis, energy balance, exergy analysis and life cycle assessment. Indeed, carbon footprint method can also be applied [27], to assess the environmental impact and sustainability of the waste recycling treatments used. The carbon footprint is a measure of the total amount of carbon dioxide emissions that is directly and indirectly caused by an activity or is accumulated over the life stages of a product [28].…”

The Circular Economy concept implies the re-design of existing production systems in agriculture, by promoting agricultural waste recycling. In an organic zucchini—lettuce rotation, two different agroecological tools were considered: biofertilizer and presence or absence of green manure (GM+ and GM−). In particular, we compared: (i) anaerobic digestate from cattle manure, co-composted with vegetable wastes, with the presence of GM (AD GM+); (ii) olive pomace compost, re-composted, with the presence of GM (OWC GM+); (iii) municipal waste compost with GM (MWC GM+); (iv) municipal waste compost without GM (MWC GM−). These materials were tested with a commercial organic fertilizer without GM (COF GM−) as a positive control. The objectives were: (i) assessing the environmental sustainability of biofertilizers through carbon footprint analysis by greenhouse gas—GHG—emissions; (ii) evaluating the agronomic performance on the vegetable rotation, by energy output assessment. The total carbon emissions of biofertilizers production was 63.9 and 67.0 kg of CO2 eq Mg−1 for AD and OWC, respectively. The co-composting and re-composting processes emitted 31.4 and 8.4 kg CO2 per Mg of compost, respectively. In AD the ventilation phase of composting accounted for 37.2% of total emissions. The total CO2 emission values for the two-crop cycles were the highest in COF GM− and the lowest in OWC GM+, due to different fertilizer sources. On the average of the treatments, the input that induced the highest CO2 emission was irrigation (37.9%). The energy output assessment for zucchini and lettuce highlighted similar performance for all the treatments. Our findings demonstrated the validity of the tested processes to recycle agro-industrial wastes, and the potential of agroecological practices (GM) to mitigate GHG emissions.

Adaptation can be a key factor that will shape the future severity of climate change impacts on food production. The objective of this study was to assess the suitability of an agro-ecological approach based on various techniques as potential adaptation strategy in organic horticultural systems. A long-term field experiment was set up in Southern Italy, combining: (i) appropriate soil surface shaping; (ii) cash crop rotation; (iii) agro-ecological service crops (ASC) introduction as living mulch and complementary crops; (iv) tailored organic fertilization; and (v) alternative tillage strategies. In this paper, the first two-year results on cauliflower (Brassica oleracea L.) and tomato (Solanum lycopersicum L.) crops, as well as energy consumptions through the Energy Analysis (EA) method are reported. Due to the climatic conditions that occurred, which were characterized by the absence of extreme climatic events (particularly rainfall), it was not possible to verify if the designed experimental device was able to mitigate the impact of climate change, whereas the EA indicated that total energy inputs were lower when ASC are introduced in cropping systems.

“…For example, Alavijeh and Yaghmaei, showed that energy recovered from biogas produced by wheat residue can provide energy input for 115.62 and 393.12 thousand hectares of irrigated and rain‐fed wheat production in Iran, respectively. Several studies have indicated that the greatest energy consumption and environmental impacts of the agricultural production in Iran was attributed to chemical fertilizers . So another way to mitigate the agricultural environmental impacts in Iran is to replace chemical fertilizer with organic fertilizers.…”

Iran is among the ten countries which has the largest share of CO2 emission and also has the highest amount among the Middle East countries. However, the agricultural sector in Iran is one of the major emitters of some greenhouse gas emissions, such as nitrous oxide. Therefore, this work aimed to study the environmental impacts of agricultural production in Iran and determine the impact category with the highest potential for the environmental damage in this region for the period of 2007–2014. For this purpose, the three impact categories of global warming potential (GWP), acidification potential (AP) and terrestrial eutrophication potential (TEP) were selected to be evaluated through Life Cycle Assessment (LCA) methodology. The results showed that the characterization indices of GWP, AP, and TEP impact categories for agricultural sector in Iran were 20,405,789 tonnes CO2eq, 303,145 tonnes SO2eq and 640,340 tonnes NOxeq, respectively for the year of 2014. For the period in question, agriculture accounted for 4%, 12%, and 26% of the GWP, AP and TEP impact categories in Iran, respectively. Overall, the TEP impact category had the greatest negative effect on the environment in term of the agricultural sector in Iran. © 2017 American Institute of Chemical Engineers Environ Prog, 37: 1750–1757, 2018
