Landrace cereals have become more popular among organic farmers in Europe. However, little is known about the response of landraces to environmental conditions and farmers’ management compared to modern cultivars. A co-designed field experiment, informed by Swedish farmers’ experiences of landrace cereals, was used to investigate how traits valued by organic farmers differ between four landrace and three modern varieties of spring wheat (Triticum aestivum L.) under different environmental conditions and depending on nutrient applications. The experiment was organically managed and consisted of four randomized complete blocks in four environments, comprising two sites during two consecutive years. The varieties responded similarly to fertilization. The most recent modern variety had the highest grain yield of all varieties but the lowest protein content. At low or medium initial availability of nitrogen, landraces were shown to yield similarly to modern organic varieties, give high and stable protein content, and in addition suppress weeds better and produce higher straw yields. In one experimental environment, the initial amount of soil mineral nitrogen was high, and all four landraces yielded considerably less than all modern varieties. These results show the potential for landraces to provide both food and ecosystem services under low-input organic conditions.

The use of wood in building construction can substitute more emission-intensive materials while storing biogenic carbon, as buildings are long-lasting stocks. Yet, increasing use of wood for buildings competes with other uses of wood and can have negative consequences for forest ecosystems. A cascadic use of wood has the potential to increase wood use and carbon storage with less primary wood. However, there is limited knowledge of how cascadic use principles can be implemented in specific regional contexts. While several building stock studies have tracked wood inflows, stocks, and outflows, they tend to lack a building component/element resolution, which is critical to inform strategies for component reuse. Furthermore, little is known about how cascadic use may influence wood inflows to the national building stocks. Hence, the objective of this study is to quantify end-of-life outflows of wood from building elements and to assess the share of these outflows that can be cascaded into new construction, thereby affecting future inflows to the building stock. This stock-model is built on dynamic material flow analysis principles and developed based on the ODYM-REC Python framework (Pauliuk & Heeren, 2020). It facilitates scenario-development with different reuse and recycling rates and lifetimes that change with time and cohort. The stock-matrix is layered by cohorts and building types, where the building types are differentiated by small or large wooden or non-wooden buildings, including load-bearing wooden structure types. Material intensity values are gathered from literature for the total mass per floor area and at the element level for the defined building types. Including building elements and separating building types and their load-bearing structure types has enabled us to develop a more granular understanding of wood use and its cascading potential. Preliminary results indicate that structural wooden elements in the walls and floors, such as columns and beams, have the highest potential for cascading because of their high structural capacity and quantity. However, barriers to large-scale reuse need to be addressed, including the challenges of dismantling buildings, requirements for quality certification, and financial and logistical constraints.
