Food, farmers, and the future: Investigating prospects of increased food production within a national context

| Type artikkel: Publisert studie

Kategori: Produksjonsmetoder, Samfunnsutvikling, Økonomi

With international food price shocks in 2008 and 2011, food security became a political priority in many countries. In addition, some politicians have recently adopted a more nationalistic stance. Against that background, this paper critically investigates the prospects of increased food production within a national context. We use a small, high-income country, Norway, as an empirical case.

It’s Not Always about Growth! Development Dynamics and Management in Food Businesses and Chains

| Type artikkel: Publisert studie

Kategori: Samfunnsutvikling, Økonomi

Growing small and medium-sized food enterprises (SMEs) face specific challenges, especially when they aim to maintain a higher quality of products and processes. While growing, they tend to converge either towards niche markets or mainstream commodity markets, and as a result sacrifice higher quality and value. In this article, we explore the growth of small and medium-sized enterprises and their related food supply chains, as well as the related challenges.

Ecological Recycling Agriculture to Enhance Agro-Ecosystem Services in the Baltic Sea Region: Guidelines for Implementation

| Type artikkel: Publisert studie

Kategori: Klima og miljø, Nitrogen og nitrogenfiksering, Næringsstoffer

Eutrophication caused by agriculture is an increasing ecological threat to the Baltic Sea. Modern, resource-efficient farming systems based on integrated plant and animal production, effective nutrient recycling and low external inputs can enhance multiple agro-ecosystem services, resulting in reduced pollution. Practical examples of such farming systems are not widespread. Therefore, the Baltic Ecological Recycling Agriculture and Society (BERAS) Implementation project aimed to foster this systemic shift.

Spring frost risk for regional apple production under a warmer climate

| Type artikkel: Publisert studie

Kategori: Eple, Frukt, Klima og miljø

Spring frosts, as experienced in Europe in April 2016 and 2017, pose a considerable risk to agricultural production, with the potential to cause significant damages to agricultural yields. Meteorological blocking events (stable high-pressure systems) have been shown to be one of the factors that trigger cold spells in spring. While current knowledge does not allow for drawing conclusions as to any change in future frequency and duration of blocking episodes due to climate change, the combination of their stable occurrence with the biological system under a warming trend can lead to economic damage increases.

Evaluating lifetime nitrogen use efficiency of dairy cattle: A modelling approach

The increased nitrogen (N) use efficiency in cattle farming is proposed as a key action to improve N management and reduce the environmental impact of cattle farming systems. Most attention has been given to lactating cow nutrition, excluding the elements of fertility, disease, and the non-lactating animals within the herd. Therefore, the aim of the current study was to develop a herd-level simulation model incorporating these elements to assess dairy farm N use efficiency.

Nutrient supply to organic agriculture as governed by EU regulations and standards in six European countries

| Type artikkel: Publisert studie

Kategori: Fosfor, Næringsstoffer

Organic farming systems need to replace nutrients exported via farm products, especially phosphorus (P) which may otherwise become depleted in soil in the long term. In Europe, EU regulations for organic production are shaping the farming systems with respect to inputs of nutrients. Permitted off-farm P sources include conventional animal manure, composted or anaerobically digested organic residues, rock phosphate, and some animal residues such as meat and bone meal.

Controlled traffic farming effects on soil emissions of nitrous oxide and methane

| Type artikkel: Publisert studie

Kategori: Klima og miljø, Produksjonsmetoder

Soil compaction affects soil aeration and gas diffusivity, and thus has a major impact on the release of greenhouse gases (GHGs) from fertilised soils. Controlled traffic farming (CTF) systems reduce the area of compacted soil by confining all field traffic to permanent traffic lanes, and a pilot trial at one long-term CTF site provided evidence of reduced soil emissions.

Fine-Tuning the Fight Against Food Waste

| Type artikkel: Publisert studie

Kategori: Klima og miljø, Matsvinn

The complex causes of consumer food waste make it difficult for commercial actors and public policy makers to develop successful foodwaste reduction campaigns. One of the essential problems is that consumer food waste seems to be the unplanned result of divergent food-related behaviors. The current research investigates the relationship between distinctive consumer food-related lifestyle patterns and food waste.

Soil carbon varies between different organic and conventional management schemes in arable agriculture

| Type artikkel: Publisert studie

Kategori: Gjødsel, Karbon og karbonlagring, Matjord

The effects of organic versus conventional farming systems on changes in soil organic carbon (SOC) has long been debated. The effects of such comparisons may depend considerably on the design of the respective systems and climate and soil conditions under which they are performed. Here, we compare a range of arable organic and conventional crop systems at three sites (Jyndevad, Foulum and Flakkebjerg) in Denmark through long-term experiments initiated in 1997.

Crop traits drive soil carbon sequestration under organic farming

1. Organic farming (OF) enhances top soil organic carbon (SOC) stocks in croplands compared with conventional farming (CF), which can contribute to sequester C. As farming system differences in the amount of C inputs to soil (e.g. fertilization and crop residues) are not enough to explain such increase, shifts in crop residue traits important for soil C losses such as litter decomposition may also play a role.

Seed coating with a neonicotinoid insecticide negatively affects wild bees

Understanding the effects of neonicotinoid insecticides on bees is vital because of reported declines in bee diversity and distribution and the crucial role bees have as pollinators in ecosystems and agriculture. Neonicotinoids are suspected to pose an unacceptable risk to bees, partly because of their systemic uptake in plants, and the European Union has therefore introduced a moratorium on three neonicotinoids as seed coatings in flowering crops that attract bees.

Risks and opportunities of increasing yields in organic farming. A review.

| Type artikkel: Publisert studie

Kategori: Økologisk landbruk

Current organic agriculture performs well in several sustainability domains, like animal welfare, farm profitability and low
pesticide use, but yields are commonly lower than in conventional farming. There is now a re-vitalized interest in increasing
yields in organic agriculture to provide more organic food for a growing, more affluent population and reduce negative impacts per unit produced. However, past yield increases have been accompanied by several negative side-effects. Here, we review risks and opportunities related to a broad range of sustainability domains associated with increasing yields in organic agriculture in the Northern European context.

Kategori: Klima og miljø

The effect of no- and reduced tillage (NT/RT) on greenhouse gas (GHG) emission was highly variable and may depend on other agronomy practices. However, how the other practices affect the effect of NT/RT on GHG emission remains elusive. Therefore, we conducted a global meta-analysis (including 49 papers with 196 comparisons) to assess the effect of five options (i.e. cropping system, crop residue management, split application of N fertilizer, irrigation, and tillage duration) on the effect of NT/RT on CH4 and N2O emissions from agricultural fields.

Agricultural intensification is a leading cause of global biodiversity loss, which can reduce the provisioning of ecosystem services in managed ecosystems. Organic farming and plant diversification are farm management schemes that may mitigate potential ecological harm by increasing species richness and boosting related ecosystem services to agroecosystems. What remains unclear is the extent to which farm management schemes affect biodiversity components other than species richness, and whether impacts differ across spatial scales and landscape contexts.

Kategori: Insekter, Pollinerende insekter

Pollination improves the yield of most crop species and contributes to one-third of global crop production, but comprehensive benefits including crop quality are still unknown. Hence, pollination is underestimated by international policies, which is particularly alarming in times of agricultural intensification and diminishing pollination services. In this study, exclusion experiments with strawberries showed bee pollination to improve fruit quality, quantity and market value compared with wind and self-pollination.

Contribution of insect pollinators to crop yield and quality varies with agricultural intensification

| Type artikkel: Publisert studie

Kategori: Insekter, Pollinerende insekter

Up to 75% of crop species benefit at least to some degree from animal pollination for fruit or seed set and yield. However, basic information on the level of pollinator dependence and pollinator contribution to yield is lacking for many crops. Even less is known about how insect pollination affects crop quality. Given that habitat loss and agricultural intensification are known to decrease pollinator richness and abundance, there is a need to assess the consequences for different components of crop production.

The quality of leguminous vegetables as influenced by preharvest factors

The cultivation of most legumes, aims to the production of either dry seeds consumed by humans, also known as pulses, or animal fodder. However, some legumes are cultivated for fresh consumption either as pods or as immature seeds. The economically most important legumes consumed as vegetables are green pods of common bean, cowpea, faba bean, snow pea (mangetout) and green pea seeds. As a rule, the legume vegetables are consumed after cooking and in many countries, they may be used to cover primary nutritional needs, because their protein content is high in comparison with most other vegetables.

This review summarises existing evidence on the impact of organic food on human health. It compares organic vs. conventional food production with respect to parameters important to human health and discusses the potential impact of organic management practices with an emphasis on EU conditions. Organic food consumption may reduce the risk of allergic disease and of overweight and obesity, but the evidence is not conclusive due to likely residual confounding, as consumers of organic food tend to have healthier lifestyles overall. However, animal experiments suggest that identically composed feed from organic or conventional production impacts in different ways on growth and development.
