- Biomass co‐firing with coal is a near‐term option to displace fossil fuels and can facilitate development of biomass conversion and the build‐out of biomass supply infrastructure. A GIS‐based modeling framework (EU‐28, Norway, and Switzerland) is used to quantify and localize biomass demand for co‐firing in coal power plants and agricultural and forest residue supply potentials; supply and demand are then matched based on minimizing the total biomass transport costs (field‐to‐gate). Key datasets (e.g., land cover, land use, wood production) are available at 1,000 m or higher resolution, while some data (e.g., simulated yields) and assumptions (e.g., crop harvest index) have lower resolution and were re‐sampled to allow modeling at 1,000 m resolution. Biomass demand for co‐firing is estimated at 184 PJ in 2020, corresponding to an emissions reduction of 18 Mt CO2. In all countries except Italy and Spain, the sum of the forest and agricultural residues available at less than 300 km from a co‐firing plant exceeds the assessed biomass demand. The total cost of transporting residues to these plants is reduced if agricultural residues can be used, since transport distances are shorter. The total volume of forest residues less than 300 km from a co‐firing plant corresponds to about half of the assessed biomass demand. Almost 70% of the total biomass demand for co‐firing is found in Germany and Poland. The volumes of domestic forest residues in Germany (Poland) available within the cost range 2‐5 (1.5‐3.5) €/GJ biomass correspond to about 30% (70%) of the biomass demand. The volumes of domestic forest and agricultural residues in Germany (Poland) within the cost range 2‐4 (below 2) €/GJ biomass exceed the biomass demand for co‐firing. Half of the biomass demand is located within 50 km from ports, indicating that long‐distance biomass transport by sea is in many instances an option.

- Brazil is home to the largest tracts of tropical vegetation in the world, harbouring high levels of biodiversity and carbon. Several biomass maps have been produced for Brazil, using different approaches and methods, and for different purposes. These maps have been used to estimate historic, recent, and future carbon emissions from land use change (LUC). It can be difficult to determine which map to use for what purpose. The implications of using an unsuitable map can be significant, since the maps have large differences, both in terms of total carbon storage and its spatial distribution. This paper presents comparisons of Brazil’s new ‘official’ carbon map; that is, the map used in the third national communication to the UNFCCC in 2016, with the former official map, and four carbon maps from the scientific literature. General strengths and weaknesses of the different maps are identified, including their suitability for different types of studies. No carbon map was found suitable for studies concerned with existing land use/cover (LULC) and LUC outside of existing forests, partly because they do not represent the current LULC sufficiently well, and partly because they generally overestimate carbon values for agricultural land. A new map of aboveground carbon is presented, which was created based on data from existing maps and an up- to-date LULC map. This new map reflects current LULC, has high accuracy and resolution (50 m), and a national coverage. It can be a useful alternative for scientific studies and policy initiatives concerned with existing LULC and LUC outside of existing forests, especially at local scales when high resolution is necessary, and/or outside the Amazon biome. We identify five ongoing climate policy initiatives in Brazil that can benefit from using this map.

Beneficial land use change : Strategic expansion of new biomass plantations can reduce environmental impacts from EU agriculture
- 2019
-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Society faces the double challenge of addressing negative impacts of current land use, while increasing biomass production to meet the future demands for food, materials and bioenergy. Potential impacts of increasing the biomass supply are subject to debate. In the discourse, land use change (LUC) has often been considered as negative, referring to impacts of deforestation and cropland expansion. At the same time, LUC is considered necessary for mitigating impacts of existing land use. Strategic establishment of suitable crop cultivation systems in agricultural landscapes can mitigate environmental impacts of current crop production, while providing biomass for the bioeconomy. Here, we explore the potential for such “beneficial LUC” in EU28, based on high-resolution land use modeling. First, we map and quantify the degree of accumulated soil organic carbon losses, wind and water erosion, nitrogen emissions to water, and recurring flooding, in ~81.000 individual sub-watersheds in EU28. We then estimate the effectiveness in mitigating these impacts through establishment of perennial plants, in each sub-watershed. Finally, we identify areas where perennialization may be particularly beneficial from an environmental point of view. The results indicate that there is a substantial potential for effective mitigation, regarding all the assessed impacts. Depending on criteria selection, some 10-46% of the land used for annual crop production in EU28 is located in landscapes that could be considered priority areas for beneficial LUC. While some recent policy development is favorable for promoting beneficial LUC, the effectiveness could be increased by seeking synergies between climate change mitigation, energy security, and other societal goals. One way forward can be to identify and promote options for biomass production in the context of SDG implementation.

Bokkapitel (övrigt vetenskapligt/konstnärligt)abstract
- This chapter presents an assessment of how biodiversity is considered in different types of sustainability standards. First, biodiversity is defined and strategies for biodiversity conservation are discussed. Then, standards for sustainable production of biomass in agriculture and forestry are evaluated on how they consider biodiversity, i.e., how they attempt to prevent actions that can threaten biodiversity and support actions that can conserve it. It is also assessed how sustainability standards address the conversion of certain ecosystem types. A broad set of standards is included relating to either sustainable agricultural management, sustainable forest management, or sustainable production of biofuel feedstocks. Similarities and differences within and between the three categories are identified. Finally, key barriers to, and challenges for, certification schemes are discussed, and recommendations are made for further development of sustainability standards. © 2016 John Wiley & Sons, Ltd.

- Sustainability certification schemes and standards are meant to prevent a range of unacceptable socioeconomic and environmental consequences, such as threats to biodiversity. While there is wide support for conserving biodiversity, opera- tionalizing this support in the form of guiding principles, criteria/indicators, and legislation is complicated. This study investigates how and to what extent 26 sustainability standards (eleven for forest management, nine for agriculture and six biofuel-related) consider biodiversity, by assessing how they seek to prevent actions that can threaten biodiversity as well as how they support actions aimed at biodiversity conservation. For this purpose, a benchmark standard was developed, meant to represent a case with very high ambitions concerning biodiversity con- servation. Of the assessed standards, the biofuel-related standards demonstrated the highest level of compliance with the benchmark. On average, they complied with 72% of the benchmark’s component criteria, compared to 61% for the agricul- tural standards and 60% for the forestry standards. Fairtrade, Sustainable Agricul- ture Network/Rainforest Alliance (SAN/RA), Roundtable on Sustainable Palm Oil (RSPO), and Roundtable on Responsible Soy (RTRS) were particularly stringent, while Green Gold Label S5 (GGLS5), PEOLG, Global Partnership for Good Agricul- tural Practices (GLOBALGAP), European Union Organic (EU Organic), National Organic Program (NOP), Green Gold Label S2 (GGLS2), and International Sus- tainability & Carbon Certification (ISCC) were particularly unstringent. All eleven forestry standards, six of the nine agricultural standards, and all six biofuel-related standards addressed ecosystem conversion, ranging from requiring that high con- servation value areas be identified and preserved to requiring full protection. Finally, key barriers to, and challenges for, certification schemes are discussed and recommendations are made for further development of sustainability standards.

Forskningsöversikt (refereegranskat)abstract
- Ecosystem services (ES) is a significant research topic with diverse modelling and mapping approaches. However, the variety of approaches—along with an inconsistent terminology—cause uncertainties concerning the choice of methods. This paper identifies and qualitatively assesses methods for mapping ES in terrestrial landscapes, based on a systematic review of the scientific literature. It further aims to clarify the associated terminology, in particular the concept of landscape and landscape scale. In total, 347 cases of ES mapping were identified in the reviewed papers. Regulating and maintenance services were most commonly mapped (165), followed by cultural (85), and provisioning services (73). For individual ES, a large variation in number of mapping cases was found. This variation may either reflect the perceived importance of the ES, or that different ES can be more or less easily mapped. Overall, Logical models and Empirical models were most commonly used, followed by Extrapolation, Simulation/Process models, Data integration, and Direct mapping. Only twelve percent of all ES mapping cases were validated with empirical data. The review revealed highly diverging views on the spatial extent of landscapes in studies of ES, and that the term landscape is sometimes used rather arbitrarily.

Oil palm for biodiesel in Brazil — risks and opportunities
- 2015

Tidskriftsartikel (refereegranskat)abstract
- Although mainly used for other purposes, and historically mainly established at the expense of tropical forests, oil palm can be the most land efficient feedstock for biodiesel. Large parts of Brazil are suitable for oil palm cultivation and a series of policy initiatives have recently been launched to promote oil palm production. These initiatives are however highly debated both in the parliament and in academia. Here we present results of a high resolution modelling study of opportunities and risks associated with oil palm production for biodiesel in Brazil, under different energy, policy, and infrastructure scenarios. Oil palm was found to be profitable on extensive areas, including areas under native vegetation where establishment would cause large land use change (LUC) emissions. However, some 40–60 Mha could support profitable biodiesel production corresponding to approximately 10% of the global diesel demand, without causing direct LUC emissions or impinging on protected areas. Pricing of LUC emissions could make oil palm production unprofitable on most lands where conversion would impact on native ecosystems and carbon stocks, if the carbon price is at the level $125/tC, or higher.
