Mapping and quantifying nature’s contributions to people underpinning international food trade
Open AccessGabriela Rabeschini, Antonio Castro et al.ARTICLESustainability Science2026References: 14
Global food systems are dependent on nature’s contributions to people (NCP), yet the role of such contributions in international trade is largely underrecognised. Using publicly available data on the configuration of natural and cultural landscapes, we developed a spatially-explicit approach to map, quantify and trace a regulating NCP (wild pollination) and a non-material NCP (supporting identities) underpinning Brazilian coffee and soy supply-ch…
The role of nature's contributions to people in sustaining international trade of agricultural products
Open AccessAlexandra Marques, Aletta Bonn et al.ARTICLEPeople and Nature2024
Nature's contributions to people (NCP) are essential for the production and trade of agricultural, forestry and fishery commodities. Often, there is a spatial disconnect between consumers and the natural systems where the commodities are produced. Traded agricultural products are therefore dependent on nature and NCP in their region of origin. The dependencies of agricultural products on NCP are, however, insufficiently recognised by consumers an…
Biodiversity impact of food waste
Open AccessJakob Bogenreuther, Thomas Koellner et al.ARTICLEJournal of Industrial Ecology2024
Reducing food waste could lower pressures on land resources and thereby contribute to the mitigation of global biodiversity loss. The reduction of food waste and biodiversity loss are also specified in the Sustainable Development Goals 12.3 and 15 of the United Nations. However, which supply chain stages and food products to target with policy measures is hardly known. Especially, a differentiation of the impact after sub‐stages and taxa is still…
Where and why is landscape considered valuable? Societal actors’ perceptions of ecosystem services across Bavaria (Germany)
Open AccessLisa Küchen, Thomas M Schmitt et al.ARTICLEEcosystems and People2023
Balancing the demand for ecosystem services (ES) with available supply is one key challenge for decision making in sustainable landscape management. ES demand is context-specific. Therefore, the assessment of perceptions articulated by multiple societal actors in different regions can help to identify differences and commonalities in predominant preferences for landscapes and their ES. The goal of this study was to investigate four societal actor…
Domestic water versus imported virtual blue water for agricultural production
Open AccessGeorg Smolka, Ervin Kosatica et al.ARTICLEJournal of Industrial Ecology2023
The supply of water, food, and energy in our global economy is highly interlinked. Virtual blue water embedded into internationally traded food crops has therefore been extensively researched in recent years. This study focuses on the often neglected energy needed to supply this blue irrigation water. It provides a globally applicable and spatially explicit approach to the watershed level for water source specific quantification of energy consump…
Climate change perceptions in Bavaria
Open AccessTheresa Landwehr, Rebekka Riebl et al.ARTICLEGAIA - Ecological Perspectives…2023
Research on perceptions of climate change has been focused on either social or environmental factors, lacking interdisciplinarity. This study bridges this gap by assessing the influence of both. Our analyses reveal societal actor group affiliation as the strongest predictor for the perception of climate change.People’s perceptions of climate change are crucial for their readiness to engage in mitigation and adaptation. To identify the most influe…

Plural valuation in space
Open AccessThomas M Schmitt, Rebekka Riebl et al.ARTICLEEcosystems and People2022
The agricultural management of grasslands not only is strongly linked to fodder production but also provides other valuable ecosystem services such as carbon sequestration, nutrient regulation, and recreation. Capturing the values that society places on such ecosystem services is a step to provide management recommendations. To elicit the societal value of grasslands and their ecosystem services, it is important to consider multiple dimensions, n…
Volksbegehren Artenvielfalt
Hanna Hartmann, Maria Haensel et al.ARTICLEGAIA - Ecological Perspectives…2021
Mit dem Volksbegehren Artenvielfalt wurden Änderungen im Bayerischen Naturschutzgesetz für besseren Arten- und Biotopschutz angestoßen. Auf Basis einer Literaturstudie betrachten wir, welches Potenzial diese Änderungen auch für Ökosystemdienstleistungen in der Agrarlandschaft haben können.The Bavarian referendum Biodiversity and Natural Beauty (Volksbegehren Artenvielfalt) has led to significant changes in Bavarian environmental legislation. This…

Quantifying interregional flows of multiple ecosystem services – A case study for Germany
Open AccessJanina Kleemann, Matthias Schröter et al.ARTICLEGlobal Environmental Change2020Cited by: 7References: 4
Despite a growing number of national-scale ecosystem service (ES) assessments, few studies consider the impacts of ES use and consumption beyond national or regional boundaries. Interregional ES flows – ecosystem services “imported” from and “exported” to other countries – are rarely analyzed and their importance for global sustainability is little known. Here, we provide a first multi-ES quantification of a nation's use of ES from abroad. We foc…

Towards a National Ecosystem Assessment in Germany
Christian Albert, Carsten Neßhöver et al.ARTICLEGAIA - Ecological Perspectives…2017
We present options for a National Ecosystem Assessment in Germany (NEA-DE) that could inform decision-makers on the state and trends of ecosystems and ecosystem services. Characterizing a NEA-DE, we argue that its cross-sectoral, integrative approach would have the advantages of increased scientific understanding, addressing specific policy questions and creating science-policy dialogues. Challenges include objections against a utilitarian perspe…

Trading Land
Open AccessA Schaffartzik, H Haberl et al.ARTICLEJournal of Industrial Ecology2015
Land use is recognized as a pervasive driver of environmental impacts, including climate change and biodiversity loss. Global trade leads to “telecoupling” between the land use of production and the consumption of biomass‐based goods and services. Telecoupling is captured by accounts of the upstream land requirements associated with traded products, also commonly referred to as land footprints. These accounts face challenges in two main areas: (1…
Global Human Appropriation of Net Primary Production for Biomass Consumption in the European Union, 1986–2007
Open AccessThomas Koellner, Thomas Kastner et al.ARTICLEJournal of Industrial Ecology2015
The ongoing globalization process strengthens the connections between different geographic regions through trade. Biomass products, such as food, fiber, or bioenergy, are increasingly traded globally, thereby leading to telecouplings between distant, seemingly unrelated regions. For example, restrictions for agricultural production or changes in bioenergy demand in Europe or the United States might contribute to deforestation in Latin America or …

Factors Influencing Households' Firewood Consumption in the Western Pamirs, Tajikistan
Open AccessBunafsha Mislimshoeva, Robert Hable et al.ARTICLEMountain Research and Development2014
Firewood is a major energy source, especially in many high mountainous regions in developing countries where other energy sources are limited. In the mountainous regions of Tajikistan, current energy consumption is limited owing to geographic isolation and numerous challenges—including in the energy sector—that emerged after the collapse of the Soviet Union and Tajikistan's independence. The sudden disruption of external supplies of energy forced…
