Trade-off relationship between modern agriculture and biodiversity: Heavy consolidation work has a long-term negative impact on plant species diversity

FEAST HQ WG4_Publications

Highlights: • Land consolidation is one of the major land-use changes in Japanese agricultural systems. • We examined the relationship between the occurrences of farmland consolidation and threatened plant species across Japan at the prefecture scale. • Results show that areas containing records of threatened plant species had rarely experienced consolidation. • We concluded that consolidated farmland areas have experienced/undergone a long-term negative impact on plant species diversity.

Straw biochar hastens organic matter degradation and produces nutrient-rich compost

FEAST HQ WG4_Publications

Highlights: • Straw biochar improved water-soluble nutrient ions contents during composting. • Straw biochar enhanced the degradation of organic matter and maturity. • The product with biochar addition became mature after composting for 42 days. • A final concentration of 10–15% straw biochar was optimal. Authors: Jining Zhang, Guifa Chen, Huifeng Sun, Sheng Zhou*, Guoyan Zou Journal: Bioresource Technology, 200:876-883 (2016) DOI: http://dx.doi.org/10.1016/j.biortech.2015.11.016

Contribution of soil moisture to seasonal and annual variations of soil CO2 efflux in a humid cool-temperate oak-birch forest in central Japan

FEAST HQ WG4_Publications

Abstract: To quantify the contribution of soil moisture to seasonal and annual variations in soil CO2 efflux in a cool-humid deciduous broadleaf forest, we measured soil CO2 efflux during the snow-free seasons of 2005–2008 using an automated chamber technique. This worked much better than manual chambers employing the same steady-state through-flow method. Soil CO2 efflux (g C m−2 period−1) during the snow-free season ranged from 979.8 ± 49.0 in 2005 to 1131.2 ± 56.6 in 2008 with a coefficient variation of 6.4 % among the 4 years. We established two-parameter (soil temperature and moisture) empirical models, finding that while soil temperature and moisture explained 69–86 % and 10–13 % of the temporal...

Potential impacts of information disclosure designed to motivate Japanese consumers to reduce carbon dioxide emissions on choice of shopping method for daily foods and drinks

FEAST HQ WG5_Publications

Abstract: Information disclosure associated with carbon dioxide emissions of goods or services may be useful for stimulating consumers to make choices to reduce carbon dioxide emissions. The scope of this study was to analyze the potential impact of information disclosure on consumer choices of daily shopping method through an internet survey of Japanese residents (2630 subjects). Japanese consumers were shown to have a preference for low carbon dioxide emissions in their choice of daily shopping method. Awareness of responsibility and intention to act were identified as crucial influences on consumer willingness to reduce carbon dioxide. Supporting information such as comparative presentation...

Development of weighting factors for G20 countries—explore the dif-ference in environmental awareness between developed and emerging countries

FEAST HQ WG5_Publications

Abstract Purpose: Weighting is one of the steps involved in LCIA. This enables us to integrate various environmental impacts and facilitates the interpretation of environmental information. Many different weighting methodologies have already been proposed, and the results of many case studies with a single index have been published. LIME2 (Itsubo et al. Int J Life Cycle Assess 17(4):488-498, 2012) developed weighting factors for four different areas of protection that reflect environmental awareness among the Japanese public. This method has already been widely used in Japan, but difficulties exist universally using the Japanese weighting factors around the world. It is presumed that...

How can Mediterranean societies thrive in an era of decreasing resources?

FEAST HQ Report, WG1_Publications

Highlights: The average Food Footprint of a Mediterranean resident is approximately 0.9 gha per person—with a range from 0.6 gha—thus higher than that of such countries as India (0.4 gha), China (0.5 gha), Costa Rica (0.6 gha) and Germany (0.8 gha). In analysis of 12 Mediterranean cities, Cairo has the highest total Ecological Footprint, followed by Barcelona and Rome. The Mediterranean cities with the highest Ecological Footprint per person are Genoa, Athens and Rome. The Mediterranean cities with the lowest Ecological Footprint per person are Antalya, Cairo and Izmur. The demand for renewable resources in Athens exceeds the entire nation...

Informal urban green-space: comparison of quantity and characteristics in Brisbane, Australia and Sapporo, Japan

FEAST HQ WG1_Publications

Abstract: Informal urban green-space (IGS) such as vacant lots, brownfields and street or railway verges is receiving growing attention from urban scholars. Research has shown IGS can provide recreational space for residents and habitat for flora and fauna, yet we know little about the quantity, spatial distribution, vegetation structure or accessibility of IGS. We also lack a commonly accepted definition of IGS and a method that can be used for its rapid quantitative assessment. This paper advances a definition and typology of IGS that has potential for global application. Based on this definition, IGS land use percentage in central Brisbane,...

Deviations between observed and RothC-simulated Δ14C values despite improved IOM initialization

FEAST HQ WG4_Publications

Summary: The 14C contents and the carbon (C) pool sizes for Rothamsted Carbon (RothC) model pools and soil fractions determined by physical separation and subsequent chemical oxidation were directly compared for an agricultural topsoil (Dystric Cambisol) from a long-term experimental field in central Japan. The RothC model was run from 1975 to 2009 and the C concentration and Δ14C value of each pool and for the bulk soil were compared with the physical fractions that have been, according to literature, suggested as corresponding with model pools. When compared with the default estimate of the inert organic matter (IOM) pool size...
