Impact changes of climatic extremes on arable farming in the north of the Netherlands

Agriculture is vulnerable to climate change in multiple ways. Here, we use the northern region of the Netherlands as a case study to explore how risk assessments for climate change impacts on crop production can address multiple vulnerabilities. We present a methodology, which we call agro climate calendar (ACC) that (i) includes potential yield losses, as well as loss of product quality, and (ii) assesses the risks of a variety of climate factors including weather extremes and the emergence and abundance of pests and diseases. Climate factors are defined for two time slices: 1990 (1976-2005) and 2040 (2026-2055); the frequency of occurrence of the factors is compared for the two periods, and the resulting frequency shifts are presented in a crop calendar on a monthly basis. This yields an indication of the magnitude and direction of changes in climatic conditions that can lead to damage by extreme events and pests and diseases. We present results for the two most important crops in the region, seed potato, and winter wheat. The results provide a good overview of risks from climate factors, and the most important threats and opportunities are identified. This semi-quantitative approach is firmly rooted in farm management, which is the level where operational and strategic decisions are made. Thus, the approach is well suited to assist local stakeholders such as farmers and policy makers to explore farm-level adaptation. This work is complementary to previous modeling work that focused mainly on the relation between mean climate change factors (i.e., temperature) and crop yield.

“…Pectobacterium and Dickeya spp. are vascular pathogens, able to infect potato tubers internally (Perombelon and Kelman 1980;Czajkowski et al 2009Czajkowski et al , 2010 and due to the ability of inhabiting the inner tuber tissues they will not be affected by the superficial treatments, thus the physical measures and chemical control agents will not effectively contribute to the control of Pectobacterium and Dickeya spp. in potato.…”

The potential for control of Dickeya solani infections in potato by elicitation of in vitro grown potato plants with salicylic acid (SA) was investigated by selective plating and confocal laser scanning macroscopy (CLSM). In replicated experiments potato plants grown on medium supplemented with 25 or 50 μM of SA were evaluated for the phytotoxic effects. Potato plants grown on medium supplemented with SA and inoculated with GFP-tagged D. solani were investigated for blackleg development and colonization of potato plants by the bacteria. Three days after inoculation, colonization of roots by D. solani was observed in 100 % control plants grown on medium without SA but not in plants grown on medium supplemented with 50 μM SA. After 14 days, 100 % of control plants showed severe disease symptoms, whereas plants grown on medium supplemented with 50 μM SA and inoculated with bacteria did not express any symptoms. After 14 days bacteria were found inside 100 % stems of control plants in densities of ca. 10 3 -10 4 cfu g −1 and inside ca. 10-15 % stems of plants treated with 50 μM SA in densities similar to these in the control plants. The GFP-tagged bacteria were macroscopically detected on the surface of the roots of control plants but not on the surface of the plants treated with 50 μM SA 14 days after inoculation. The implications of SA treatments on plant fitness and disease development are discussed.

“…Bacterial soft rot disease is commonly found in potato growing regions worldwide (Perombelon, 2002;Czajkowski et al, 2009). Several studies have shown that the soft rot causal agents are too divergent to be included in one clade (Knwon et al, 1997;Hauben et al, 1998).…”

“…The new classification grouped the genus Erwinia into Pectobacterium (formally Erwinia carotovora) and Dickeya spp., according to the differences of pectolytic enzymes secreted through type II secretion system. Two species, Dickeya chrysanthmi and Pectobacterium carotovorum are particularly damaging to potato production (Toth et al, 2001;Czajkowski et al, 2009). P. carotovorum is a highly diverse species and is currently divided into five subspecies: atrosepticum, betavasculorum, carotovorum, odoriferum and wasabiae (Hauben et al, 1998) with subspecies carotovorum and atrosepticum causing rotting of potato during vegetative growth and in stored tubers.…”

Bacterial soft rot disease is one of the most important factors affecting potato production in Jordan. Based on biochemical and physiological analyses, Jordanian isolates of soft rot from potato were identified as Pectobacterium carotovorum subspecies carotovorum (DYE 1969). Phylogenetic analysis using pmrA gene sequence data showed that isolates from different regions were closely related to each other, whereas little genetic diversity was observed between these isolates. A DNA marker was developed from nucleotide sequences of the pmrA gene and a 318 bp fragment was polymerase chain reaction (PCR) amplified specifically from P. carotovorum subspecies carotovorum isolates, which could be used for detection of the disease in potato tubers.
