The objective is to critically examine the methodologies and associated parameters used in existing regulatory schemes for calculating GHG emissions, and to explore methodological convergences. The issues related to direct lifecycle and indirect land use change emissions have been addressed. It is found that there are commonalities between the European Renewable Energy Directive (EU-RED) and the UK's Renewable Transport Fuels Obligation (UK-RTFO), but the US-EPA's Renewable Fuel Standard (US-EPA) and the Low Carbon Fuel Standard of the California Air Resources Board (CA-CARB) vary greatly not only among themselves, but also in relation to the European regulations. Agricultural practices (especially soil carbon and nitrogen dynamics), co-product credits from surplus electricity and uncertainties around economic modeling approaches for indirect land use change are the major areas where methodological divergences exist. Incorporation of domestic agricultural practices, sugarcane mills operations, and realistic modeling of indirect impacts of land use change using regional models could provide more coherence in estimations of GHG emissions. Furthermore, the Brazilian trend of novelty in all phases of sugarcane bioenergy systems should be considered when projecting GHG emissions. ref.

In order to reach such purpose, a typology of farmers was elaborated for the watershed. Two farmer types were selected for a detailed study: small farmers with low technology and citrus producers. The productive structure of both types was modeled through the recursive programming method, comprising the period between 2002/03 and 2008/09. The current farm system adopted by each type was confronted with two scenarios for legal reserve compensation: (I) through the reallocation of productive areas within the farms and sustainable management of natural vegetation recovery in order to explore the production of timber; (II) through the spontaneous growth of natural vegetation. Results highlight the importance of policies aimed to obtain a more equitable distribution of environmental conservation costs in the society, as we l as the importance of locational adjustments of the legal reserves, in order to reach a better equilibrium between the preservation of biodiversity and the opportunity cost of land. ref.

Animals were fed (DM basis) 10% barley straw and 90% concentrate (32.2% barley grain, 27.9% ground corn, 7.5% wheat bran, 10.7% soybean meal, 10.7% soybean hulls, 7.2% corn gluten feed, 3.1% mineral-vitamin mix; 16.6% CP, 18.3% NDF). Treatments were no additive (CTR), 125 (CAP125), 250 (CAP250), and 500 (CAP500) mg/d of capsicum oleoresin standardized with 6% of capsaicin and dihydrocapsaicin (XTract 6933, Pancosma, Geneva, Switzerland). Each experimental period consisted of 25 d (15 d for adaptation, 5 d of continuous measurement of DMI, and 3 d for rumen sample collection). Animals had ad libitum access to water and feed offered once daily at 0800 h. Data were analyzed by the MIXED procedure of SAS. The model included the f xed effects of period and treatment, the random effect of heifer, and the residual error. The effects were tested for linear and quadratic effects. A linear response was observed (CTR, CAP125, CAP250, and CAP500, respectively) for DMI (8.56, 9.84, 8.68, and 9.40 kg/d; P<0.04), ruminal pH (6.03, 5.84, 5.96, and 5.86; P<0.08) and total VFA (134.3, 144.8, 140.1, and 142.8 mM; P<0.08). There was a strong correlation between water consumption and DMI (R2=0.98). Dry matter intake in the first 2 h after feeding was reduced (P<0.05) in all CAP treatments compared with control. The molar proportion of acetate tended to decrease linearly (from 59.6 to 55.5 mol/100 mol; P<0.06), and ammonia N concentration tended to increase linearly (from 14.4 to 16.0 mg N/dL; P<0.08). In contrast, the molar proportion of propionate (23.8 mol/100 mol), butyrate (14.2 mol/100 mol), and lactate (0.28 mol/100 mol) were not affected by treatments. Resu ref.

Based on a representative nutrition survey in Germany from the year 2006, a life cycle assessment (LCA) was conducted to quantify nutrition-related emissions of animal and plant-based foods (excluding beverages), with a special focus on the socio-demographic factor gender. Materials and methods: For the study, representative data sets concerning German food production and consumption were used. These were complemented by the Danish LCA Food database and other LCA data to analyse the impact of food imports. As regards environmental impact assessment, global warming potential (GWP) was assessed, which included emissions from direct land use change and land use (dLUC, LU), along with three inventory indicators (ammonia emissions, land use, blue water use). The following food groups were analysed from cradle-to-store and their impa ts were evaluated and compared with each other: animal-based foods (meat products, milk products, egg products and fish products), plant-based foods (grain products, vegetables, fruits, potato products, margarine/oils, sugar/sweets). The reference year in the study is the year 2006. Results and discussion: For all indicators, the results show strong variation between the genders. Even if the physiologically different consumption patterns among men and women are adjusted on a weight basis, men show a higher impact in terms of GWP (CO2 eq. +25%), ammonia emissions (+30%) and land use (+24%). In contrast, women demonstrate a higher water demand (+11%). These differences are primarily caused by a higher share of meat and meat products in the usual diet of men (+28%) as well as of fruit and vegetables in the diet of women (+40%). If men were to shift qualitatively to the usual diet of women, then 14.8 Mt CO2 eq. and 60.1 kt ammonia emissions coul ref.

This paper sets out to describe the environmental impact assessment for wood charcoal briquettes produced from eucalyptus wood in Brazil, with specific reference to those impacts associated with Global Warming Potential. To achieve that objective, the work was undertaken in accordance with ISO 14040 "Environmental management Life cycle assessment Principles and framework" which describes essential LCA characteristics and good practices. Charcoal briquettes are produced from two basic raw materials, charcoal fines and starch. The fines result from the production of charcoal from sustainably managed eucalyptus plantations. Starch is extracted from baba_u pulp in the Amazon region. Multioutput processes were allocated based on income from the different by-products. The results showed that more than 90% of incoming CO2 was due to biomass production for charcoal, and the remainder to starch biomass production. Based on Brazilian data, as well as information provided by the GaBi4.3 database, it turned out hat supplying the energy content of 1_kg of briquettes resulted in the sequestration of 3.9690_kg of CO2, i.e. around 4_kg of CO2 per kg of briquettes produced. CO2 emissions throughout the briquette production process are totally compensated for by the environmental quality of the raw materials used. ..." ref.

Costa Rica is the largest exporter of fresh pineapple to US and European markets and production area has tripled since 2002 with associated economic benefits and environmental concerns. A detailed life cycle assessment of fresh pineapple from the farm to retail shelf in the US was performed to characterize the range of environmental performance and identify important sources of environmental impact and opportunities for improvement. Participating producers representing three major production regions and a range of field conditions and management practices provided data to support the assessment. Impacts estimated included energy demand, carbon footprint, stress-weighted water footprint, soil erosion, emergy, human and ecosystem toxicity, and others from TRACI with models customized for Costa Rican conditions. Using the functional unit of 1 serving of fruit for comparative purposes, pineapple likely has a higher energy demand and carbon footprint than common tree fruits such as apples and oranges becaus it is more input intensive but causes less water stress because of ideal climatic conditions in Costa Rica. The farming stage was the most important source of impacts and thus provides the most opportunities for improvements; packaging was significant due to the packing material, and refrigeration is the primarily contributor to impact during distribution, although it is a small contribution to overall impact. Selecting flat terrain, maximizing the yield:input ratio, packing in reusable cartons without crowns, and using energy-efficient refrigeration can provide significant reduction of measureable impacts, but these need to be considered alongside other impacts such as worker health and site-specific ecological and human risks that are not typically part of LCA. This approach and selected impact indicators provide a model for characterizing environmental performance of other fruits, especially in the humid tropics. ..." ref.

Life Cycle Assessment (LCA) was applied to two smallholder milk production systems in Peru in order to evaluate the environmental burden of milk produced in each. An Andean highland milk production system where livestock feeding is restricted to permanent pastures supplemented with on farm grown ryegrass-clover was opposed to a coastal system with dairy cows fed a diet consisting of fodder maize and

purchased concentrate. Milk production levels (kg/cow day) differed considerably with 2.57 for the highland and 19.54 for the coastal system. A Life Cycle Inventory was calculated for the functional unit of 1_kg energy corrected milk (ECM) and the environmental impacts global warming, acidification and eutrophication were estimated for 1_kg ECM, 1_ha and 1 animal, considering the multi-functionality of the system. The highland system was characterized by a high land use (23.1_m2a/kg ECM vs. 1.71_m2a/kg ECM at the coast). Irrigation water and energy were on the other hand used to a much higher amount at the oast (7291_l/kg ECM and 8791_MJ/kg ECM, respectively) than in the highlands (848_l/kg ECM and 0.20_MJ/kg ECM). Global warming potential, acidification and eutrophication were higher for 1_kg ECM produced in the highlands than at the coast by 10.6_kg CO2 equivalents, 6.58_g sulfur dioxide equivalents and 10.63_g phosphate equivalents, respectively. Nevertheless, 5220_kg CO2 equivalents more were emitted per animal at the coast than in the highlands. Also acidification and eutrophication were estimated to be on average 6 and 4 times higher at the coast compared to the highlands when expressed for the functional units of 1_ha and 1 animal.ResultsWhereas livestock is mainly responsible for impacts on the environment in the highlands, at the coast both livestock related emissions and forage cultivation play an important role.

Purpose China is the largest producer of textile-dyeing products in the world. The production of these materials consumes high amounts of water and energy and results in the discharge of huge amounts of pollutants. This study aimed at evaluating the life-cycle environmental impacts of the textile-dyeing industry and determining the key processes for mitigating life-cycle environmental impacts efficiently and effectively, which will benefit the application of cleaner production technologies. Methods A life-cycle assessment was performed according to the ISO 14040 standard series. The system investigated includes the dyeing process and final disposal and the transportation of raw material, energy production, and transportation. The functional unit is 10,000 m of cotton fabric, which weighs 2,000 kg. Our study encompasses three types of data. The data regarding the production process and the major raw materials, necessary energy, and the source of the energy, as well as the emissions of some pollutants, w re provided by a textile-dyeing enterprise in Jiangsu Province. The data regarding transport were generated using the GaBi version 4.3 database. Some emission factor data such as those on CO 2 , CH 4 , and N 2 O emissions were obtained from the literature. Resources, energy consumption, and emissions are quantified, and some of the potential environmental effects were evaluated using the CML2001 method built into the GaBi version 4.3 database. Results and discussion Scouring and oxygen bleaching, dyeing, stentering and setting, wastewater treatment, and incineration are the key processes in terms of global warming potential, acidification potential, photochemical ozone creation potential, and eutrophication potential. It will therefore be useful to enhance the recycling of water, control the consumption of additives and dyes, and conserve energy as much as possible.

--> An increasing demand for food together with a growing demand for energy crops result in an increasing demand for and competition over water. Sugar cane, sugar beet and maize are not only essential food crops, but also important feedstock for bio-ethanol. Crop growth requires water, a scarce resource. This study aims to assess the green, blue and grey water footprint (WF) of sweeteners and bio-ethanol from sugar cane, sugar beet and maize in the main producing countries. The WFs of sweeteners and bio-ethanol are mainly determined by the crop type that is used as a source and by agricultural practise and agro-climatic conditions; process water footprints are relatively small. The weighted global average WF of sugar cane is 209 m3/tonne; for sugar beet this is 133 m3/tonne and for maize 1222 m3/tonne. Large regional differences in WFs indicate that WFs of crops for sweeteners and bio-ethanol can be improved. It is more favourable to use maize as a feedstock for sweeteners or bio-ethanol than sugar beet or suga cane. The WF of sugar cane contributes to water stress in the Indus and Ganges basins. In the Ukraine, the large grey WF of sugar beet contributes to water pollution. In some western European countries, blue WFs of sugar beet and maize need a large amount of available blue water for agriculture. The allocation of the limited global water resources to bio-energy on a large scale will be at the cost of water allocation to food and nature. NR - 34 p. ref. [K60/120231804](PASCAL)

The water footprint (WFP) of a product is the volume of water used along the supply chain to make that product. Green-water represents the store of soil water from rainfall that is transpired by the crop. Blue-water represents the store of ground and surface water that may be used for irrigation. Grey-water represents the amount of freshwater needed to assimilate a load of pollutants given natural background concentrations and existing water quality standards. We set up a field experiment in a commercial apple orchard to monitor the soil water balance and to measure nitrate leaching losses. Sap-flow data from apple trees and time-domain reflectometry (TDR) data from root-zone soil are used to quantify changes in the green-water store. Irrigation volumes are used to represent changes in the blue-water store. Passive-wick flux meters installed below the root-zone are used to monitor drainage and leaching losses of nitrate in order to quantify changes in the grey-water component. We demonstrate how this field data, along with mechanistic computer modelling, can be used quantify the water footprint of an apple orchard in the Hawke's Bay, New Zealand. Model-measurement comparisons are very important to provide growers, industry and regulators with confidence in the quality of the data and appropriateness of the models used to determine footprints. ref.

Australia, which has imposed stringent SPS requirements, registered a declining import volume of Philippine fresh pineapple as shown by a significant and negative coefficie t of SPS dummy variable. In general, in spite of the insignificant effect of SPS measures on total value of Philippine pineapple exports, there are still production-, marketing-, and trade-related problems in the industry that require policy directions in order to remain competitive in traditional and emerging foreign markets. ref.

Especially for developing countries, there are concerns that genetically modified crops fail to benefit smallholder farmers and contribute to social and economic hardship. Many economic studies contradict this view, but most of them look at short-term impacts only, so that uncertainty about longer-term effects prevails. We address this shortcoming by analyzing economic impacts and impact dynamics of Bt cotton in India. Building on unique panel data collected between 2002 and 2008, and controlling for nonrandom selection bias in technology adoption, we show that Bt has caused a 24% increase in cotton yield per acre through reduced pest damage and a 50% gain in cotton profit among smallholders. These benefits are stable; there are even indications that they have increased over time. We further show that Bt cotton adoption has raised consumption expenditures, a co mon measure of household living standard, by 18% during the 2006-2008 period. We conclude that Bt cotton has created large and sustainable benefits, which contribute to positive economic and social development in India. ref.

In this system, the water consumption, as well as plant growth and crop yield, is affected by the ionic concentration of nutrient solution. Therefore, the aim of this work was to evaluate growth, yield and water consumption and use efficiency (WUE) of summer squash plants growing in raw rice husk medium with recirculating nutrient solution according to the ionic concentration of nutrient solution. Two experiments were conducted in spring-summer and summer-autumn crop-seasons, in Pelotas RS, south of Brazil. Four ionic concentrations of nutrient solution supplied to the crop were evaluated: 1.3, 1.7, 2.1 and 4.2 dS/m. The water consumption was not affected by the ionic concentration in spring-summer (139.9 L/plant). In summer-autumn, the increasing of ionic concentration increased the water consu ption (from 41.6 to 71.6 L/plant). Ionic concentrations equal or lower than 1.7 dS/m decreased growth and yield in both crop-seasons and, in spring-summer, reduced the WUE related to fresh and dry mass fruits production. In summer-autumn, ionic concentration did not affect WUE (37.8 L of water per kg of fruit fresh weight and 0.98 g of fruit dry mass production per L of water). According to the adjusted mathematics models, the electrical conductivity that maximizes (respectively in spring-summer and summer-autumn) the fruits dry mass (259.4 and 78.31 g/plant) and crop yield (7.8 and 3.7 kg/m2) for both crop-seasons and WUE (21.5 L of water/kg of fruit fresh weight and 1.94 g of fruit dry mass/L of water) in spring-summer is approximately 3.0 dS/m. Ionic concentrations greater than 3.0 dS/m reduced fruits and shoot dry mass, yield and WUE in spring-summer. ref.

This article examines methods for analyzing allocation in life cycle assessment (LCA); it focuses on comparisons of economic allocation with other feasible alternatives. The International Organization for Standardization's (ISO) guideline 14044 indicates that economic allocation should only be used as a last resort, when other methods are not suitable. However, the LCA literature reports several examples of the use of economic allocation. This is due partly to its simplicity and partly to its ability to illustrate the properties of complex systems. Sometimes a price summarizes complex attributes of product or service

quality that cannot be easily measured by physical criteria. On the other hand, economic allocation does have limitations arising, for example, from the variability of prices and the low correlation between prices and physical flows. This article presents the state of the debate on the topic and some hypothetical examples for illustration. A general conclusion is that it is not possible to determine one best allocation method. The allocation procedure has to be selected on a case-by-case basis and no single approach is suitable for every situation. Despite its limitations, economic allocation has certain qualities that make it flexible and potentially suitable for different contexts. In some situations, economic allocation should not be the last methodological resort. The option of economic allocation should be considered, for example, whenever the prices of coproducts and coservices differ widely. ..." (Source Internet) ref.

We specified the five plant types for evaluating the impacts of biogas utilization and the co-location of ethanol production at existing cassava starch factories and assessed the life-cycle GHG emissions of these plant types. The results showed that the amount of GHG emission reduction in cassava ethanol production depended on the plant type. Substantial GHG savings are achieved by ethanol plants that use biogas produced during wastewater treatment as fuel. Using biogas for steam generation is more effective in reducing GHG emissions than using it for electricity generation. Plants co-located with starch factories have advantages in relation to GHG emissions when compared with stand-alone plants. However, the impact of co-location is limited because cassava starch factories are not energetically self-sufficient. Improvement analysis suggested hat boiler efficiency and the energy source for steam generation are key factors for reducing GHG emissions. ref.

An important part of mankind put their hopes in the positive effect of agro fuels and other renewable sources of energy on climatic change. Nevertheless, these productions have an unquestionable negative environmental impact. The sustainability of agro fuel production is analysed on the basis of Thermodynamic Laws and it is demonstrated that all economic processes convert low entropy sources in wastes. The consumption of fossil fuel energy in bioethanol production from maize and sugarcane is analysed as well as their waste generation. Some aspects of biodiesel production from microorganisms are presented and their perspectives are emphasized as they do not compete for land for food production. ref.

The pre-farm stage included GHG emissions from agricultural machinery and chemical production, and transport of raw materials (spawn, peat, and compost) in mushrooms. The on-farm stage included GHG emissions from agricultural machinery operation, chemical use, water for irrigation, waste generated, as well as electricity and energy consumption. The post-farm stage included transport of produce to Distribution Center (DC), storage in DC, and transport to retail outlets. The hotspots or the stages that emit the highest GHG were determined for strawberries, button mushrooms and romaine/cos lettuces. The results have shown that the life cycle GHG emissions of strawberries and lettuces were higher than mushrooms due to in ensive agricultural machinery operations during the on-farm stage. Mushrooms, however have significantly higher GHG emissions during pre-farm stage due to transport of peat, spawn, and compost. ref.

Data were collected from randomly selected 120 rice growers using pre-tested interview schedule during 15 January to 14 February, 2011. Majority of the respondents were found old aged having no education level, small family size, medium farm size, medium level annual income, medium extension contact, medium organizational participation, low participation in farming and medium innovativeness. The findings revealed that, in case of dependent sub variable production and soil management aspects; farmers education, family size, farm size, annual income, extension media contact, organization participation, direct participation in farming and innovativeness in rice farming had positive significant correlation, but age had negative significant relationship. Moreover, in case of dependant sub-variable environmental aspects; extension media contact, organizational participation, direct participating in far ing and innovativeness in rice farming had positive significant relationship. Besides, in case of dependent sub variable economic aspects; direct participation in farming had positive significant relationship. Furthermore, in case of dependent sub-variable socio-cultural aspects; only direct participation in farming had positive significant relationship where farm size had negative significant relationship. Best alternative to rice monoculture may be 'Rabi (potato/ vegetable/ mustard/ pulse) - Maize - T.Aman rice' for medium high land and 'Rabi - Fallow - B. Aman' for medium low land. Though, rice monoculture has negative impact on environment and other selected aspects but farmers are interested to adopt it because of staple food crop, easy to marketing and bringing more benefit than other competing crops. ref.

Purpose Life cycle impact assessment (LCIA) is a field of active development. The last decade has seen prolific publication of new impact assessment methods covering many different impact categories and providing characterization factors that often deviate from each other for the same substance and impact. The LCA standard ISO 14044 is rather general and unspecific in its requirements and offers little help to the LCA practitioner who needs to make a choice. With the aim to identify the best among existing characterization models and provide recommendations to the LCA practitioner, a study was performed for the Joint Research Centre of the European Commission (JRC). Methods Existing LCIA methods were collected and their individual characterization models identified at both midpoint and endpoint levels and supplemented with other environmental models of potential use for LCIA. No new developments of characterization models or factors were done in the project. From a total of 156 models, 91 were short li ted as possible candidates for a recommendation within their impact category. Criteria were developed for analyzing the models within each impact category. The criteria addressed both scientific qualities and stakeholder acceptance. The criteria were reviewed by external experts and stakeholders and applied in a comprehensive analysis of the short-listed characterization models (the total number of criteria varied between 35 and 50 per impact category). For each impact category, the analysis concluded with identification of the best among the existing characterization models. If the identified model was of sufficient quality, it was recommended by the JRC. Analysis and recommendation process involved hearing of both scientific experts and stakeholders. Results and recommendations Recommendations were developed for 14 impact categories at midpoint level, and among these recommendations, three were classified as satisfactory while ten were in need of some improveme ref.

Although resources are generally used efficiently, greenhouse areas cause major environmental impacts. The aim of this work was to study, from an environmental point of view, the improvement capacity of greenhouse areas in the Mediterranean region and to assess several alternative agricultural practices to decrease their contribution to the environmental impacts in this system. Materials and methods: The methodology used was life cycle assessment (LCA) based on a tomato crop grown in a multi-tunnel greenhouse in Almeria, on the southeast coast of Spain. The functional unit chosen was 1 ton of loose classic tomatoes. Five midpoint impact categories and one energy flow indicator were selected for their relevance. The agricultural practice alternatives evaluated were reduction of volume of substrate and fertilizers, extension of substrate a d greenhouse life span and increase in renewable energy for electricity production. Results and discussion: The results indicated that the main contributors to impact categories in the tomato production were structure, auxiliary equipment and fertilizers. Structure accounted for between 30 and 48% of the contributions, depending on the impact category. The principal burdens in the auxiliary equipment stage were substrate and consumption of electricity. Fertilizers environmental impacts were due to emissions during their manufacture and application to the crop. In a best-case option, taking into account the best alternatives, contributions to the impact categories were reduced by between 17 and 30%. The LCA methodology proved to be a useful tool to evaluate the environmental damage of this agricultural activity.

Mill mud is a by-product of the sugar milling process and is considered a rich source of nutrients, in particular nitrogen, phosphorus and calcium. Mackay Sugar (MSL) produces approximately 400 000 tonnes of mill mud per year which is subsequently returned to cane fields in trucks. By elevating the tipper body and using a paddle in the tailgate, these trucks have traditionally distributed the mud in a largely ad hoc manner. The trucks are driven over the field applying mud at a nominal rate of 150 tonnes of wet mud per hectare (t/ha), but in-field measurements show wide variability in application rates. Mackay Sugar had deemed this method of application as unacceptable to their growers and has set about finding alternative solutions to application rates and methods. Mackay Sugar, in association with Reef Catchments Mackay Whitsunday, funded a project that sought to addre s the issues of mill mud application. Consolidated Plastics and Epoxy Qld Pty Ltd were engaged to design and fabricate the applicators to be fitted onto the back of the existing mud truck fleet. The brief details of the design included: the ability to spread across three rows; the ability to control the rate at differing row spacing; control of the rate to a minimum of 50 tonnes of wet mud per hectare; must not add excessive weight to the back of the truck; and applicators must be able to be fitted onto existing truck bodies and use the existing truck hydraulic components with minimum truck modifications. The resultant applicators have been established and fitted to several trucks applying mud throughout the Mackay Sugar region in 2010. This method of application has delivered the following benefits: mud has been placed in the centre of the plant growth row; no mud is distributed onto the wheel tracks where the ground is more likely to have been compacted and is ref.

The procedure is essential for environmental assessment of ethanol from molasses, a co-product of sugar which has long been used mainly for feed. We compare system expansion and two allocation procedures for estimating greenhouse gas (GHG) emissions of molasses ethanol. As seen from our results, system expansion yields the highest estimate among the three. However, no matter which procedure is used, a significant reduction of emissions from the fuel stage in the abatement scenario, which assumes implementation of substituting bioenergy for fossil-based energy to reduce GHG emissions, combined with a negligible level of emissions from the use stage, keeps the estimate of ethanol life cycle

GHG emissions below that of gasoline. Pointing out that indirect land use change (ILUC) is a consequence of diverting molasses from feed to fuel, system expansion is the most adequate method when the purpose of the LCA is to support decision makers in weighing the options and consequences. As shown in the sensitivity analysis, an addition of carbon emissions from ILUC worsens the GHG balance of ethanol, with deforestation being a worst-case scenario where the fuel is no longer a net carbon saver but carbon emitter. ref.

This paper presents two case studies of applying the Life Cycle Assessment (LCA) and Water Footprint (WF) approaches to tea and margarine. The WF, excluding grey water, of a carton of 50_g tea is 294_L green water and 10_L blue water, and that of a 500_g tub of margarine is 553_L green water, 109_L blue water. The inventory results in the LCA studies (blue water) are 13_L for tea and 114_L for margarine. In the impact assessment phase of WF, Coonoor in Southern India appears as a potential hotspot for tea production, although the water consumed in energy to boil the kettle and by the consumer are also significant. For margarine the main potential hotspot is irrigated sunflower around Zaporizhia in Ukraine. The impact assessment results of LCA for tea causes the water in the consumer use phase to be down-weighted and stresses the contribution from Coonoor due to the higher water scarcity of this region Similarly the LCA impact assessment of margarine causes the palm oil contribution to be down-weighted due to the low water scarcity of Medan in Indonesia. From these case studies we identify similarities, differences and synergies at both the water accounting and impact assessment levels for both approaches with the purpose of improving and advancing the water resource assessment process. ref.
