“…Increased crop diversity supports increased above and below ground biodiversity (Köpke and Nemecek 2010) including decomposer invertebrates such as earthworms and Collembola (Eisenhauer et al 2009;Sabais et al 2011) and pollen-and nectar-gathering wild and domesticated bees as well as bumblebees that are attracted by the crop's mass-flowering habit (Stoddard and Bond 1987;Palmer et al 2009;Green et al 1980;Köpke and Nemecek 2010;Westphal et al 2003). However, benefits of increased diversity of crops and associated diversity are not rewarded in current markets due to institutional failures (Perrings 2001;Pascual and Perrings 2007).…”

Sustainable development of agriculture is at the core of agricultural policy debates in Europe. There is a consensus that diversification of cropping would support sustainable development. However, a reduction in legume cultivation has been observed in the EU during the last decades. This decline has induced, in turn, a deficit of proteins and a reduction of ecosystem services provided by legumes. Therefore, we analysed the mechanisms that shape agricultural systems to identify leverage points for reviving European legume production. Specifically, we reviewed the factors that affect the market and non-market value of legumes and the relevant agricultural policies. We characterized the decline in legume cropping as an outcome of the dominance of economic forces that favour specialization of production systems over diversification. We found that the value of market outputs of legumes per unit area is relatively low and volatile, with a 25-78 % variation in pea gross margins, which reduces market competitiveness. We observed that the value of systeminternal outputs of legumes such as the nitrogen fixed, of 130 to 153 kg N ha; crop protection services that reduce agrochemical costs, by 20-25 % in cereals; and yield enhancements of subsequent crops, of 0.2 to 1.6 t ha −1 in cereals, are often underestimated. In addition, markets fail to translate external effects of legumes such as biodiversity enhancement, reduction in emissions, of up to 50 % in N 2 O, and soil improvements into economic benefits. Current policies support legumes through selected mechanisms such as ecological focus areas, agri-environmental programmes and sparse coupled support measures. Domestic cultivation of legumes could be supported through trade policies such as import restrictions on genetically modified soybean or new mechanisms to appreciate non-market outputs including payments for ecosystem services and carbon markets. In addition, development of new value chains, niche markets, scaling-up of plant breeding efforts and dissemination of information is required.

“…If honey bees exhibit selective visitation behavior in F 1 seed production fields, pollen flow between the two lines might be insufficient to achieve economically acceptable production of F 1 seed. With the negative impacts predicted from climate change, the collapse of ecosystems due to decreasing pollinator activity, and colony collapse disorder of honey bee colonies in the United States, both contribution and consequence of insect pollinators, especially honey bees, to crop production have recently been reviewed (Palmer et al 2009). To enhance F 1 seed productivity through the efficient application of pollinators, including honey bees and native insects, we must fully understand the pollination process and its effect on F 1 seed production in the field.…”

For F 1 seed production in Brassicaceae crops, cross-pollination between the two parental lines is vital and is dependent on the visitation behavior of insect pollinators. In a radish F 1 seed production field using cytoplasmic male sterility system, visitation behaviors of different pollinator species and seed productivity of the recipient line were investigated in three stages during the flowering. As a result, honey bees (Apis mellifera and A. cerana) selectively visited either of two lines, while syrphid flies (various flies belonging to Syrphidae) tended to visit both lines. Despite the few observations of pollinator movements between the two lines, all flowers had received cross-pollen grains a few days after flowering. But in the late stage of flowering, increased cross-pollination by syrphid flies appeared to lead to an increase in the amount of crosspollen grains deposited on the stigmas. The percentage of pod set and the number of seeds per pod varied among the three stages of the flowering. These variations might be caused by shifts in the amount of crosspollen grains deposited on the stigmas due to the pollinators' selective visitation behaviors. The selective visitation behavior of insect pollinators could potentially result in unstable F 1 seed production through the insufficient cross-pollination.

Abstract:The ongoing debate about the use of genetically-modified (GM) crops in agriculture has largely focused on food safety and genetic contamination issues. Given that the majority of GM crops have been produced to respond to the problem of crop yield reductions caused by diseases, insects and weeds, the paper argues that in those cases, the currently used GM crops are an unstable solution to the problem, because they represent such a strong selection pressure, that pests rapidly evolve resistance. Organic agriculture practices provide a more sustainable way of producing healthy food; however, the lower yields often associated with those practices, making the resultant healthy food more expensive, open the criticism that such practices will not be able to feed human populations. Evolutionary plant breeding offers the possibility of using the evolutionary potential of crops to our advantage by producing a continuous flow of varieties better adapted to organic systems, to climate change and to the ever changing spectrum of pests, without depending on chemical control.
