Meeting Sustainability Requirements for SRC Bioenergy: Usefulness of Existing Tools, Responsibilities of Involved Stakeholders, and Recommendations for Further Developments
2012
Ingår i: Bioenergy Research. - : Springer Science and Business Media LLC. - 1939-1234 .- 1939-1242. ; 5:3, s. 606-620

Short rotation coppice (SRC) is considered an important biomass supply option for meeting the European renewable energy targets. This paper presents an overview of existing and prospective sustainability requirements, Member State reporting obligations and parts of the methodology for calculating GHG emissions savings within the EU Renewable Energy Directive (RED), and shows how these RED-associated sustainability criteria may affect different stakeholders along SRC bioenergy supply chains. Existing and prospective tools are assessed on their usefulness in ensuring that SRC bioenergy is produced with sufficient consideration given to the RED-associated criteria. A sustainability framework is outlined that aims at (1) facilitating the development of SRC production systems that are attractive from the perspectives of all stakeholders, and (2) ensuring that the SRC production is RED eligible. Producer manuals, EIAs, and voluntary certification schemes can all be useful for ensuring RED eligibility. However, they are currently not sufficiently comprehensive, neither individually nor combined, and suggestions for how they can be more complementary are given. Geographical information systems offer opportunities for administrative authorities to provide stakeholders with maps or databases over areas/fields suitable for RED-eligible SRC cultivation. However, proper consideration of all relevant aspects requires that all stakeholders in the SRC supply chain become engaged in the development of SRC production systems and that a landscape perspective is used.

Nästa steg för ekologiskt lantbruk – eko 3.0
2016
Rapport (populärvet., debatt m.m.) abstract
Hur kan ekologisk produktion och konsumtion utvecklas för att bättre svara mot framtidens stora globala utmaningar? Den nya skriften bygger på broschyren "Organic 3.0 for truly sustainable farming & consumption" som tagits fram av IFOAM, internationell paraplyorganisation för ekologiskt lantbruk, kompletterat med reflektioner kring vad Eko 3.0 kan innebära för svenska förhållanden.

Precaution and Ethics: Handling risks, uncertainties and knowledge gaps in the regulation of new biotechnologies
2017
Bok (övrigt vetenskapligt/konstnärligt) abstract
This volume outlines and analyses ethical issues actualized by applying a precautionary approach to the regulation of new biotechnologies. It presents a novel way of categorizing and comparing biotechnologies from a precautionary standpoint. Based on this, it addresses underlying philosophical problems regarding the ethical assessment of decision-making under uncertainty and ignorance, and discusses how risks and possible benefits of such technologies should be balanced from an ethical standpoint. It argues on conceptual and ethical grounds for a technology neutral regulation as well as for a regulation that not only checks new technologies but also requires old, inferior ones to be phased out. It demonstrates how difficult ethical issues regarding the extent and ambition of precautionary policies need to be handled by such a regulation, and presents an overarching framework for doing so.

Climate change and ecological intensification of agriculture in sub-Saharan Africa : A systems approach to predict maize yield under push-pull technology
2023
Ingår i: Agriculture, Ecosystems and Environment. - 0167-8809 .- 1873-2305. ; 352
Tidskriftsartikel (refereegranskat) abstract
Assessing effects of climate change on agricultural systems and the potential for ecological intensification to increase food security in developing countries is essential to guide management, policy-making and future research. ‘Push-pull’ technology (PPT) is a poly-cropping design developed in eastern Africa that utilizes plant chemicals to mediate plant–insect interactions. PPT application yields significant increases in crop productivity, by reducing pest load and damage caused by arthropods and parasitic weeds, while also bolstering soil fertility. As climate change effects may be species- and/or context-specific, there is need to elucidate how, in interaction with biotic factors, projected climate conditions are likely to influence future functioning of PPT. Here, we first reviewed how changes in temperature, precipitation and atmospheric CO2 concentration can influence PPT components (i.e., land use, soils, crops, weeds, diseases, pests and their natural enemies) across sub-Saharan Africa (SSA). We then imposed these anticipated responses on a landscape-scale qualitative mathematical model of maize production under PPT in eastern Africa, to predict cumulative, structure-mediated impacts of climate change on maize yield. Our review suggests variable impacts of climate change on PPT components in SSA by the end of the 21st century, including reduced soil fertility, increased weed and arthropod pest pressure and increased prevalence of crop diseases, but also increased biological control by pests’ natural enemies. Extrapolating empirical evidence of climate effects to predict responses to projected climate conditions is mainly limited by a lack of mechanistic understanding regarding single and interactive effects of climate variables on PPT components. Model predictions of maize yield responses to anticipated impacts of climate change in eastern Africa suggest predominantly negative future trends. Nevertheless, maize yields can be sustained or increased by favourable changes in system components with less certain future behaviour, including higher PPT adoption, preservation of field edge density and agricultural diversification beyond cereal crops.

Biocultural Refugia : Combating the Erosion of Diversity in Landscapes of Food Production
2013
Ingår i: Ecology & Society. - 1708-3087. ; 18:4, s. UNSP 71-
Tidskriftsartikel (refereegranskat) abstract
There is urgent need to both reduce the rate of biodiversity loss caused by industrialized agriculture and feed morepeople. The aim of this paper is to highlight the role of places that harbor traditional ecological knowledge, artifacts, and methodswhen preserving biodiversity and ecosystem services in landscapes of food production. We use three examples in Europe ofbiocultural refugia, defined as the physical places that not only shelter farm biodiversity, but also carry knowledge and experiencesabout practical management of how to produce food while stewarding biodiversity and ecosystem services. Memory carriersinclude genotypes, landscape features, oral, and artistic traditions and self-organized systems of rules, and as such reflect adiverse portfolio of practices on how to deal with unpredictable change. We find that the rich biodiversity of many regionallydistinct cultural landscapes has been maintained through different smallholder practices developed in relation to localenvironmental fluctuations and carried within biocultural refugia for as long as millennia. Places that transmit traditionalecological knowledge and practices hold important lessons for policy makers since they may provide genetic and culturalreservoirs — refugia — for the wide array of species that have co-evolved with humans in Europe for more than 6000 thousandyrs. Biodiversity restoration projects in domesticated landscapes can employ the biophysical elements and cultural practicesembedded in biocultural refugia to create locally adapted small-scale mosaics of habitats that allow species to flourish and adaptto change. We conclude that such insights must be included in discussions of land-sparing vs. land-sharing when producingmore food while combating loss of biodiversity. We found the latter strategy rational in domesticated landscapes with a longhistory of agriculture
