Ecuador es el tercer exportador de rosas a nivel mundial. Un factor clave para la competitividad internacional es calcular y reducir las emisiones de gases de efecto invernadero (GEI). Por ello, se calculó la huella de carbono (HC) del cultivo de rosas en Ecuador, tomando como caso de estudio la Empresa Ecoroses S.A. en el año 2015. La empresa está ubicada en el cantón Mejía, provincia de Pichincha y dedica el 100% de su producción a las rosas. La HC se calculó mediante dos metodologías: GHG Protocol y PAS 2050, considerando los límites del sistema “de la cuna a la puerta”. Los factores de emisión fueron recopilados de bases de datos internacionales como IPCC y Ecoinvent v2.2. El resultado de la HC fue de 3,75 kg CO2eq/kg de rosa exportada. Las tres fuentes de emisión de GEI que más afectan son: los productos agrícolas (37,7%), la energía eléctrica (13,3%) y el uso de combustibles fósiles (10,95%). Esta HC duplica a la del cacao seco y es más de 8 veces mayor que la del banano nacional. Por ello, se propone implementar buenas prácticas ambientales para reducir los GEI, en concreto, fertilizantes orgánicos, ahorro energético y biocombustibles. Abstract Ecuador is the third largest exporter of roses worldwide. A key factor for the international competitiveness is to calculate and reduce greenhouse gases (GHG). For this reason, we calculated the carbon footprint (CF) of the cultivation of roses in Ecuador, taking as a case study the Company Ecoroses S.A. in the year 2015. The company is located in the canton Mejia, province of Pichincha, and dedicates 100% of its production to roses. The CF was calculated using two methodologies, GHG Protocol and PAS 2050, considering the limits of the system “from the cradle to the door”. The emission factors were compiled from international databases such as IPCC and Ecoinvent v2.2. The result of the CF was 3,75 kg CO2eq/kg of rose exported. The three sources of emission of GHG that most affect are: agricultural products (37,7%), electrical energy (13,3%), and the use of fossil fuels (10,95%). This CF doubles that of dry cocoa, and is more than 8 times higher than that of domestic bananas. Therefore, the implementation of good environmental practices is proposed to reduce GHG, specifically, organic fertilizers, energy saving, and biofuels.

Climate change is an important global environmental threat. Agriculture aggravates climate change by increasing greenhouse gas (GHG) emissions, and in response, climate change reduces agricultural productivity. Consequently, the modern agricultural development mode has progressively transformed into a kind of sustainable development mode. This study aimed to determine the environmental impact and carbon footprint of Dongshan tea from Yilan County. Environmental impact was assessed with use of SimaPro version 8.0.2 and IMPACT2002+. Results showed that climate change has the largest impact upon it in general, followed by human health, natural resources, and ecosystem quality. Furthermore, with use of the IPCC 2007 100a method for carbon footprint of products (CFP), conventional tea was found to have a CFP of 7.035 kgCO2-e, and its main contributors are the raw material (35.15%) and consumer use (45.58%) phases. From this case study, we found that the hotspots of the life cycle of environmental impact of Taiwanese tea mainly come from fertilizer input during the raw material phase, electricity use during manufacturing, and electricity use during water boiling in the consumer use phase (which contributes the largest impact). We propose the ways for consumers to use of highly efficient boiling water facilities and heating preservation, and the government must market the use of organic fertilizers in the national policy subsidies, and farmers have to prudent use of fertilizers and promote the use of local raw fertilizers, and engagement in direct sales for reducing the environmental impacts and costs of agricultural products and thus advancing sustainable agriculture development.

Carbon footprint (CF) analysis is widely used to quantify the greenhouse gas (GHG) emissions of a product during its life cycle. A number of protocols, such as Publicly Available Specification (PAS) 2050, GHG Protocol Product Standard (GHG Protocol), and ISO 14067 Carbon Footprint of Products (ISO 14067), have been developed for CF calculations. This study aims to compare the criteria and implications of the three protocols. The medium-density fiberboard (MDF) (functional unit: 1 m3) has been selected as a case study to illustrate this comparison. Different criteria, such as the life cycle stage included, cut-off criteria, biogenic carbon treatment, and other requirements, were discussed. A cradle-to-gate life cycle assessment (LCA) for MDF was conducted. The CF values were −667.75, −658.42, and 816.92 kg of carbon dioxide equivalent (CO2e) with PAS 2050, GHG protocol, and ISO 14067, respectively. The main reasons for the different results obtained were the application of different cut-off criteria, exclusion rules, and the treatment of carbon storage. A cradle-to-grave assessment (end-of-life scenarios: landfill and incineration) was also performed to identify opportunities for improving MDF production. A sensitivity analysis to assess the implications of different end-of-life disposals was conducted, indicating that landfill may be preferable from a GHG standpoint. The comparison of these three protocols provides insights for adopting appropriate methods to calculate GHG emissions for the MDF industry. A key finding is that for both LCA practitioners and policy-makers, PAS 2050 is preferentially recommended to assess the CF of MDF.

Olive Groves

Olive groves are representative of the landscape and culture of Spain. They occupy 2.5 M ha (1.5 M ha in Andalusia) and are characterised by their multifunctionality. In recent years, socio-economic and environmental factors (i.e., erosion) have compromised their sustainability, leading farmers to abandon their farms or intensify their management. The main objective/purpose of this research was to study the drivers and concerns that condition farmers’ choice of a given olive grove management model. Taking the Estepa region as a case study (Andalusia, Spain), surveys were conducted among farmers with integrated and organic managed olive groves. The socio-economic aspects were the main objectives and concerns of the farmers with integrated olive groves. In the case of farmers with organic management, conservation objectives prevailed, and their concerns were oriented to environmental threats. The education level was a key factor in the adoption of given farm management, as it increased the level of environmental awareness. In the context of multifunctional agriculture, it would be desirable to increase this awareness of the environmental threats against olive groves, in order to provide incentives for the implementation of agri-environmental practices that would enhance the sustainability of these systems.

As a contribution to the fight against climate change, ESNE’s 2018/19 carbon footprint has been evaluated using the CarbonFeel methodology, based on ISO 14069 standards. In the scenario studied, greenhouse gas (GHG) emissions produced by direct and indirect emissions have been included. For comparative purposes, a second scenario has been analyzed in which fossil fuels used for heating are replaced by electrical energy from renewable sources. A decrease of 28% in GHG emissions has been verified, which could even reach 40% if the energy for thermal conditioning was replaced by renewables.

The paper presents valuation of the local electro-energetic carbon footprint on the islands of Cres and Lošinj (The Northern Adriatic, Republic of Croatia). In the form of a case study the article isolates the locally allocated but globally present environmental burden caused by CO2 emission into the atmosphere as the result of electrical energy production. Within the environmental burden, the residents’ footprint and the footprint generated by tourism have been isolated. The hypothesis the article is based on presumes that the local electro-energetic carbon footprint is dominantly under the influence of tourism and shows annual oscillations closely related to the number of tourists on the islands. The article's contribution on theoretical level is the actualization of partial tourist footprints isolation, while on applicative level its contribution is in footprint calculations as a foundation for articulation of sustainable development strategies and spatial planning based on the actual human influence on the environment. The overall aim of the work is to contribute to revitalization and sustainable development of the islands as exceptionally valuable naturally preserved areas.

In several developing countries, the electricity crisis obstructs both socio-economic and technological sustainable evolution. Also, it leads to reducing job availability due to shut down several industries or relocate to neighbouring countries to such an issue. A Najaf City is an important holy and tourist city in the middle of Iraq country. Indeed, waste management in An Najaf City needs to be reconsidered to be used as an energy source. In this article, we investigated and listed the waste quantity which produced recently (one year) respect to waste types and types of content. Data collected from the waste products for one year and are used as a key factor to study the feasibility of generating electrical energy from collected MSWs. The proposed model was simulated and tested respect to cost analysis factor of the suggested power plant by Homer pro simulation software. Results were very encouraging and competitive to the current energy production cost based on the production cost of the Kwh prospective among the conventional methods in Iraq. The proposed scenario provide proper and secure waste proposal technique with low-cost.

<p><em>The consistent growth in certified organic farming and demand for organic foods has fostered a companion movement towards employing organic growing methods for land care. With the objective of evaluating the agronomic potential for organic land care, I conducted a case study on my property in Monroe, NJ following land disturbance from construction. After the site was remediated with deep tillage to alleviate compaction and amended with compost and limestone based on soil tests it was seeded in September 2009 with a mix of modern turf type Kentucky bluegrass cultivars. Once established, this lawn was attractive, competitive against most weeds, and performed well over the following six years under organic management. This lawn was mowed frequently with the clippings always returned so as to recycle nutrients in place. It remained attractive without fertilizer input. In 2014, another organic lawn study was established at my farm in Ringoes, NJ to evaluate several organic fertilizers. Observations from this second case study indicated that soil test P was a key factor for turf establishment. Experience with the organic lawn in Ringoes, when contrasted to the results in Monroe, suggested that rapid germination and establishment of a dense turf stand is very important to preventing weeds during establishment</em><em>. </em></p>

The study aimed to reveal the competitiveness of the world dried sector for some selected products such as dried apples, prunes, apricots, figs, and grapes. In the study, the data was subjected to the Revealed Comparative Advantage (RCA), Relative Export Advantage (RXA), Relative Import Advantage (RMA), Relative Trade Advantage (RTA) and Relative Competitiveness (RC) indices. RCA is an index developed by Balassa to determine the competitiveness of a specific country for selected products or goods. To demonstrate the economic outlook for the world dried sector, the 2007 to 2017 data of China, USA, Chile, Germany, Iran, the Netherlands, South Africa, France, Uzbekistan, Argentina, Spain, Turkey, and India were compared, these countries dominating the sector of selected dried agricultural products. The results demonstrated that the world dried sector is very responsive to economic crises and to local currency rate. The RCA index was found to be 4.66 in 2007 for Turkey and it decreased to 4.45 by 2009 during the world economic crisis. The other breaking point was 2013 when Turkey experienced both economic and political crises.

The food industry is responsible for supplying the food demand of the ever-increasing global population. The food chain is one of the major contributors to greenhouse gas (GHG) emissions, and global food waste accounts for one-third of produced food. A solution to this problem is preserving crops, vegetables, and fruits with the help of an ancient method of sun drying. For drying agricultural and marine products, several types of dryers are also being developed. However, they require a large amount of energy supplied conventionally from pollutant energy sources. The environmental concerns and depletion risks of fossil fuels persuade researchers and developers to seek alternative solutions. To perform drying applications, sustainable solar power may be effective because it is highly accessible in most regions of the world. Greenhouse dryers (GHDs) are simple facilities that can provide large capacities for drying agricultural products. This study reviews the integration of GHDs with different solar technologies, including photovoltaic (PV), photovoltaic-thermal (PVT), and solar thermal collectors. Additionally, the integration of solar-assisted greenhouse dryers (SGHDs) with heat pumps and thermal energy storage (TES) units, as well as their hybrid configuration considering integration with other renewable energy sources, is investigated to improve their thermal performance. In this regard, this review presents and discusses the most recent advances in this field. Additionally, the economic analysis of SGHDs is presented as a key factor to make these sustainable facilities commercially available.
