“…Equivalence Factors (EQFs) reflect the areas provided or required from each specific land use types into the equivalent areas of the global average bioproductivity of different land use categories (global hectares) ( Table 2) (Borucke et al, 2013;Lin et al, 2016). EQFs are the same for all countries, and change slightly from year to year.…”

“…Yields Factors (YFs) are the ratio of the average yield of the area of each land use type utilized per year from a region, compared to the larger region (Lin et al, 2016). They may reflect natural factors such as differences in precipitation or soil quality, as well as differences in anthropogenic factors, including management practices (Borucke et al, 2013).…”

Biocapacity in the Gili Matra Region: A Spatial Assessment of The Carrying Capacity of Small Islands

et al. 2017

Spatial as a contributor to biological productivity and ecosystem services have not been considered in the sustainable development of small islands. The aim of this study to appraise biocapacity (BC) in the Gili Matra Islands to estimate the existing carrying capacity for sustainable development, and refines the current BC methodology that emphasizes the spatial aspects in small islands. Based on analysis results, the Gili Matra Islands have BC total ranging from 659.46 to 1,069.57 gha in 2010, and increased from 673.64 to 1,093.02 gha in 2014. The highest total BC is the Gili Trawangan Island, while the lowest is the Gili Meno Island, but for the local BC is the opposite. The total local BC per island can be supplied around 0.00857 gha per capita for the Gili Ayer Island, 0.20103 gha per capita for the Gili Meno Island, and 0.00344 gha per capita for the Gili Trawangan Island. They are influenced by total persons or demanders. The BC values indicate a critical position, both per-unitarea or per-capita, which is spatially nearly 100% of the needs supplied from outside the island, and demonstrate the use on the Gili Matra Region have exceeded the existing carrying capacity. The sustainable development aspects and land use management should be applied strictly to ensure the sustainability of natural resources, social and economic, as well as cotinuously consider the efforts and existing strategies of conservation. The export and import factors of bioproductivity should be considered in making long-term planning. Spatially, BC appraisal was applicable to illustrate the condition of an area on the small islands. The GIS based BC can give the information of pattern of changes and distributions, both spatial and temporal. However, the statistical data use is needed to get the value of BC per capita.

Environmental Implications of Discarding Fish in Northern Spanish Coastal Bottom Otter Trawl Fisheries

et al. 2020

Overfishing contributes to the depletion of fish stocks. Among fishing practices, discarding fish is a waste of valuable resources and results in lost income that is associated with the impact on future stock growth. This practice depends on several factors, although the highest quantity of discards is produced in trawl fisheries. In this work, the impacts of a specific fraction of the Galician (northwest Spain) bottom trawl fishery were evaluated using the ecological footprint, focusing on the contribution of the discarding rate. The fishing grounds and carbon footprints were the categories that were selected for the analysis. The results showed that 11.6 global hectares per ton of catch were required for an average fishing trip, ranging between 2.2 and 27.1. Discards represented 55% of this value, while the carbon footprint only represented 11%.Therefore, measures are needed to reduce the significant impact of discards, especially in these fisheries. The findings indicate that the discard ban promoted by the Common Fisheries Policy could reduce the ecological footprint of these fisheries by 3.4 global hectares per ton of catch landed on average.

Using the water footprint concept for water use efficiency labelling of consumer products: the Greek experience

Freshwater is crucial for food supply, as irrigation water and as production or incorporated water in industrial production of consumer goods (e.g. food, cosmetics). Manufacturing industries follow different protocols and receive different certifications for water management and efficiency in their plants, which are also labelled on the packaging. Nowadays, consumers appear to be increasingly concerned about environmental challenges, therefore many sustainability labels have been developed (carbon, water, ecological footprint) to facilitate consumers to make more sustainable choices concerning their purchases. Consumers’ behaviour towards carbon footprint labels has been thoroughly examined in international literature; however, WF labelling studies are very limited. The key to water efficiency labelling in consumer products could be the water footprint (WF), as it measures the total volume of freshwater used to produce a product, over the full supply chain, including virtual water, “hidden” in the products, services and processes. The implementation of WF labelling of consumer products in Greece was investigated, using a questionnaire with demographical data and statements on water sustainability. The results indicate that younger consumers are not quite aware of environmental challenges related to water. According to the findings, WF could be an effective marketing driver towards water sustainability since consumers prefer a quantified label concerning water consumption, regardless of their educational level, and they are willing to pay an extra price for water sustainable products even if they have an unstable job. Manufacturers could then promote their sustainable profile and performance effectively by adopting a WF relevant labelling.
