Abstract The agriculture sector is both a significant consumer of energy and water and a major source of environmental pollution and greenhouse gases. Soybean production (Glycine max) has experienced a fast growth and it is the fourth most widely cultivated crop, leading to serious environmental concerns. This study evaluates the energy, carbon, and water footprints of China’s soybean production so that key environmental impacts can be identified. To provide reliable results for decision-making, uncertainty analysis is conducted based on the Monte Carlo model. Results show that the impact on climate change, fossils depletion, ecosystem quality, human health, and resource was 3.33×103 kg CO2 eq (GSD2 = 1.87), 343.37 kg oil eq (GSD2 = 1.60), 6.18×10− 5 Species·yr (GSD2 = 1.81), 3.26×10− 3 DALY (GSD2 = 1.81), and 89.22 $ (GSD2 = 2.28), respectively. Freshwater ecotoxicity was the dominant contributor (77.69%) to the ecosystem quality category, while climate change (85.22%) was the dominant contributor to the human health category. Key factors analysis results show that diammonium phosphate and diesel, and on-site emissions from soybean production, were the major contributors to the overall environmental burden of soybean production. Several policy recommendations are proposed, focusing on trade structure optimization, technological improvements, and efficient resource use. Such policy recommendations provide valuable insights to those decision-makers so that they can prepare appropriate mitigation policies.

This paper provides a comparative analysis using the concept of life cycle assessment (LCA), between high-sulfur (3000 ppm) and low-sulfur diesel (500 ppm) diesel. The comparative LCA considers the stages of production, transport and oil refining , as well as the transport of refined products and their respective end use. This last stage of the life cycle is important for the analysis of potential environmental impacts, due to sulfur oxide (SOx) emissions, which contribute to the formation of acid rain, damage air quality and the ecosystem (land and water acidification), causing gradual damage to human health and the environment. Therefore, comparative LCA identifies critical points from the environmental perspective, weighing the contributions of pollutants (NO2, CH4 and CO2) known as greenhouse gases (GHG) and criteria pollutants (CO, SOX, NOX, VOC's and PM). Simapro 7.2® was used to simulate and evaluate potential environmental impacts generated during the production and use by end consumers of the two fossil fuels. In order to evaluate the impact categories, two methods available in said calculation tool were selected: the first is the IPCC-2007 (GWP-100years), which estimates the carbon footprint and the contributions of each stage of the production chain to the "Global Warming" effect. The second method of evaluation is the Impact 2002+, which assesses the various contributions to the categories of toxicity to "Human Health", "Ecosystem Quality", "Climate Change" and "Depletion of Natural Resources". Thus, the preliminary results of comparative LCA show a slight increase in the carbon footprint (total emissions of CO2 equivalent in the productive chain) of low-sulfur diesel, approximately 3.8% compared to high-sulfur diesel, as a result of the increased emissions generated by the operation of the hydrogenation plant. However, low-sulfur diesel achieves a significant reduction of about 80% in comparison with high-sulfur diesel, in terms of damage to "Human Health" and "Ecosystem Quality". On the contrary, there was an increase of 2% and 6% in the categories of "Climate Change" and "Depletion of Natural Resources", respectively. Finally, despite the minor increase in the carbon footprint, although with remarkable reductions in "Ecosystem Quality" and "Human Health", the production and use of low-sulfur diesel has a single score of environmental impact equivalent to 0.23 milli points (mPt) compared to the single score obtained by high-sulfur diesel of 1.23 (mPt).

Abstract. Air pollution is a serious environmental and health issue in Malaysia due to the recent urbanization processes. The main sources of air pollutants are motorized vehicles in urban areas and airports and industrial activities. At the airports, NO2 is the main pollutant of concern besides aerosols particles, yet gap in data availability prevent studies to describe their patterns and quantify their effects on human health and climate change. In this study NO2 data from TROPOMI sensor on board Sentinel 5-P satellite was used to characterize the spatial and temporal patterns of NO2 tropospheric column amounts at major airports in Malaysia. The results demonstrate that NO2 amounts from aircrafts and ground traffic activities are generally higher and/or similar to the amounts found in urban areas. Total tropospheric column amounts of NO2 during the movement restriction imposed due to Covid-19 pandemic between March and April 2020 was approximately 50% lower the total emission during the same period in 2019 (representing a business as usual period). Assessing the spatial pattern and temporal variations in NO2 (both surface and total vertical profile) is important for monitoring the impact of air pollutants on climate change and human health in Malaysia.

Abstract: According to Ministry of Finance of Pakistanin the year 2016-17, agriculture sector contributed to GDP 19.8% and employees about 42.3% a labor force in country. Pakistan has been ranked 7th  in climate change by theGlobal climate rise index in 2017, this rank indicates a great challenge for the Pakistan in agriculture sector due to further climate change in future.There are few gases such as greenhouse gases, CO2, carbon dioxide, methane and nitro oxide that mainly are responsible for changes to global climate. The climate change leads to change in rainfall, sea level and flow of water due to increase in temperature. There are many variables which may affect output of agriculture sector of Pakistan but in this study author mainly focused temperature and rainfall in terms of climate change.  This study is based on secondary data from year 2000 to 2015.The monthly data of temperature and rainfall has been collected from world economic indicator and 12 months’ data was divided for converting these variables into average. Agriculture GDP output collected from Economic Survey of Pakistan’s various annual issues.  Agriculture GDP output in terms of percentage, average rainfall mm andaverage temperature in centigradevariables have been used for the conclusion ofmain objective of this study.Data analyzed through various statistical techniques such as unit root test, OLS regression analysis and Johnson co-integration in E-view 7 version.The estimated results revealed that theaverage rainfall mm has negative and significant impact but average temperature has positive and insignificant impact on agriculture GDP output in terms of percentage in short run.

The Impact

It is necessary for a country to make its agriculture sector efficient to enhance food security, quality of life and to promote rapid economic growth. The evidence from least developed countries (LDCs) indicates that agriculture sector accounts for a large share in their gross domestic product (GDP). Thus the development of the economy cannot be achieved without improving the agriculture sector. According to the Economic Survey of Pakistan (2011-12) its main natural resource is arable land and agriculture sector’s contribution to the GDP is 21 percent. The agricultural sector absorbs 45 percent of labour force and its share in exports is 18 percent. Given the role of agricultural sector in economic growth and its sensitivity to change in temperature and precipitation it is important to study the impact of climate change on major crops in Pakistan. There are two crops seasons in Pakistan namely, Rabi and Kharif. Rabi crops are grown normally in the months of November to April and Kharif crops are grown from May to October. These two seasons make Pakistan an agricultural economy and its performance depends on the climate during the whole year. Climate change generally affects agriculture through changes in temperature, precipitation.

National Food Security

Agriculture sector, being the dominant user of fresh water (70%) is highly vulnerable to climate change in Pakistan. Increase in frequency of floods and drought, rising temperatures and changes in rainfall pattern across the country during the recent years are clear indicators of changing climate. Climate change has serious repercussions for national food security as farmers have limited knowledge and technologies for mitigating the adverse effects of climate change on crop productivity. This situation is expected to decrease yield of major food crops. There exists dire need to make an intensive analysis of situation to identify existing knowledge and technology gaps and suggest doable measures for multiple stake holders like policy makers, scientists and farmers accordingly. This review paper covers the impact of climate change on agriculture and presents strategies to adapt to climate change. Strategies at policy/government level include increased funds for research, improvement of national capacity building (training of trainers) and development of a localized smart early warning system for climate change related events. Key research areas being identified to address vulnerability include development of innovative water use efficient technologies, zone specific agronomic research, applied root research, organic farming to increase soil resilience and research on ground water recharge and quality using simulation models. Farmers shall be sensitized about the issue of climate change through education and every effort shall be made to make proper use of existing farm resources and technologies to live with the changing climate so that national food security is not compromised.
