    Monitoring agricultural field trafficability using Sentinel-1
    Carranza, Coleen ; Benninga, Harm J. ; Velde, Rogier van der; Ploeg, Martine van der - \ 2019

    Agriculture - Decoupling - Kernel density estimation - Sentinel-1 - Soil moisture - Trafficability

    The use of heavy mobile machinery in agriculture for tillage and harvesting is now indispensable since it facilitates farming over large areas. However, one of the impacts of regular and prolonged use of heavy mobile machinery is soil compaction. To help minimize this harmful effect, trafficability of agricultural fields needs to be determined. Soil moisture acts as one of the dominant controls for field trafficability. Therefore satellites such as Sentinel-1, which is one source of spatio-temporal soil moisture information, could be useful in assessing trafficable conditions. One limitation of satellite-derived soil moisture is that only the upper surface layer is mapped. In this study, we determined the feasibility of Sentinel-1 surface soil moisture to monitor trafficability over 2016–2017. We first determined coupled conditions when surface soil moisture is a good indicator for values at the subsurface. We applied a probabilistic approach to determine trafficability using extensive in situ measurements of penetration resistance and surface soil moisture over a variety of crops. Trafficability is expressed as the probability that penetration resistance will exceed a threshold, for a given soil moisture value. Furthermore, we investigated the variability encountered from these measurements to gain insights on other temporal controls. Our results show coupled conditions for soil moisture ≥0.19 cm3 cm−3 and there is an almost 1:1 correspondence between surface and subsurface values. For decoupled conditions, values at the subsurface can be two times more than the surface. An increase in penetration resistance variability coincided with the maturity of crops for cultivated fields. Aside from soil moisture, root growth may have a significant impact on the temporal variability of soil's penetration resistance. The status of trafficability can be monitored through the high temporal resolution of Sentinel-1. However, aggregation to coarser resolutions maybe necessary as its original 10 m resolution may be suboptimal, based on validation against in situ measurements. Days favorable for traffic were observed in early spring. This information can aid farmers in the timing of tillage activities or for water managers in deciding to adjust water levels to meet agricultural demands.

    children - functional gastrointestinal disorders - gut microbiota - probiotics

    Objective: The objective of this study was to investigate the effect of probiotics on functional abdominal pain disorders (FAPD) and functional constipation (FC). Methods: A systematic review was conducted, searching PubMed and Cochrane databases from inception to January 2018 for randomized controlled trials (RCTs) investigating the efficacy of probiotics in children aged 4 to 18 years with FAPD or children aged 0 to 18 years with FC. Results: A total of 657 citations were identified. Finally, 11 RCTs for FAPD and 6 RCTs for FC were included. Some evidence exists for Lactobacillus rhamnosus GG (n=3) in reducing frequency and intensity of abdominal pain in children with irritable bowel syndrome. There is no evidence to recommend L. reuteri DSM 17938 (n=5), a mix of Bifidobacterium infantis, Bifidobacterium breve and Bifidobacterium longum (n=1), Bifidobacterium lactis (n=1) or VSL#3 (n=1) for children with FAPD. No evidence exists to support the use of Lactobacillus casei rhamnosus LCR35 (n=1), B. lactis DN173 010 (n=1), B. longum (n=1), L. reuteri DSM 17938 (n=1), a mix of B. infantis, B. breve and B. longum (n=1), or Protexin mix (n=1) for children with FC. In general, studies had an unclear or high risk of bias. Conclusions: Insufficient evidence exists for the use of probiotics in FAPD and FC, only L. rhamnosus GG seems to reduce frequency and intensity of abdominal pain but only in children with irritable bowel syndrome. A better understanding of differences in gut microbiota in health and disease might lead to better probiotic strategies to treat disease.

    Het onderzoeksproject ‘Optimizing Water Availability with Sentinel-1 Satellites’ heeft als doel te onderzoeken hoe satellietdata gebruikt kan worden in het Nederlandse waterbeheer. Het onderzoek laat zien dat de satelliet Sentinel-1 buiten het groeiseizoen om al een vrij goed beeld geeft van het bodemvochtgehalte. Hiermee kan bijvoorbeeld de berijdbaarheid van landbouwpercelen in kaart gebracht kan worden. Ook is met Deltares en HKV een data-assimilatietool ontwikkeld die ingezet kan worden om simulaties met het Landelijk Hydrologisch Model te verbeteren.

    Infant colic: mechanisms and management
    Zeevenhooven, Judith ; Browne, Pamela D. ; Hoir, Monique L'; Weerth, Carolina de; Benninga, M.A. - \ 2018

    Infant colic is a commonly reported phenomenon of excessive crying in infancy with an enigmatic and distressing character. Despite its frequent occurrence, little agreement has been reached on the definition, pathogenesis or the optimal management strategy for infant colic. This Review aims to delineate the definitional entanglement with the Rome IV criteria, which were published in 2016, as the leading, most recent diagnostic criteria. Moreover, neurogenic, gastrointestinal, microbial and psychosocial factors that might contribute to the pathophysiology of infant colic are explored. This Review underlines that a comprehensive medical history and physical examination in the absence of alarm symptoms serve as guidance for the clinician to a positive diagnosis. It also highlights that an important aspect of the management of infant colic is parental education and reassurance. Management strategies, including behavioural, dietary, pharmacological and alternative interventions, are also discussed. Owing to a lack of large, high-quality randomized controlled trials, none of these therapies are strongly recommended. Finally, the behavioural and somatic sequelae of infant colic into childhood are summarized.

    We have established a soil moisture profile monitoring network in the Raam region in the Netherlands. This region faces water shortages during summers and excess of water during winters and after extreme precipitation events. Water management can benefit from reliable information on the soil water availability and water storing capacity in the unsaturated zone. In situ measurements provide a direct source of information on which water managers can base their decisions. Moreover, these measurements are commonly used as a reference for the calibration and validation of soil moisture content products derived from earth observations or obtained by model simulations. Distributed over the Raam region, we have equipped 14 agricultural fields and 1 natural grass field with soil moisture and soil temperature monitoring instrumentation, consisting of Decagon 5TM sensors installed at depths of 5, 10, 20, 40 and 80 cm. In total, 12 stations are located within the Raam catchment (catchment area of 223 km2), and 5 of these stations are located within the closed sub-catchment Hooge Raam (catchment area of 41 km2). Soil-specific calibration functions that have been developed for the 5TM sensors under laboratory conditions lead to an accuracy of 0.02 m3 m−3. The first set of measurements has been retrieved for the period 5 April 2016–4 April 2017. In this paper, we describe the Raam monitoring network and instrumentation, the soil-specific calibration of the sensors, the first year of measurements, and additional measurements (soil temperature, phreatic groundwater levels and meteorological data) and information (elevation, soil physical characteristics, land cover and a geohydrological model) available for performing scientific research.

    Dutch protected horticulture is exposed to notifiable phytosanitary pests which are listed in the Quarantine list of the European Union (European Union, 2000). It is uncertain when or which quarantine pest will occur and what financial consequences this will have. These financial consequences stem from measures to be undertaken by growers, as legally required by the European Union (EU, 2000).
    A method is presented to derive the probability distribution of phytosanitary costs, which can be used by government and industry to assess risk premiums and to determine the financial consequences of some subsidy on insurance premiums to create an adequate insurance fund. Volume streams and transmission of pests have been simulated for each subsequent product chain stage. Monte Carlo simulation is used to account for uncertainties in the probability of introduction, transmission and detection of a phytosanitary pest. The probability of phytosanitary costs was calculated for a number of selected crops in Dutch protected horticulture. These crop results has been enlarged for all the crops in protected horticulture.

    Adoption of eBusiness in the Dutch horticulture
    Robbemond, R.M. ; Verdouw, C.N. ; Benninga, J. - \ 2017
    Digital exchange of information is becoming increasingly standard practice in horticulture. This development is catalysed by a trend of upscaling that is ongoing in all horticultural subsectors. Still, there is a large group of growers that is not, or poorly equipped to participate in this digital, online movement. This research focusses on the adoption of eBusiness by the growers that lag behind in the digitalisation of information exchange. Therefore the main objective of this research is to identify the drivers and barriers for exchanging information digitally between growers and other actors in horticulture supply chains. The research is based on 17 in-depth interviews with growers and 6 expert interviews. It was conducted in collaboration with Plantion, a market place for flowers and plants, and Floricode, an industry association that registers, codes, standardizes and distributes information and data to support the international floriculture supply chain.

    The Raam soil moisture measurement network dataset contains soil moisture and soil temperature measurements for 15 locations in the Raam, which is a 223-km2 river catchment in the southeast of the Netherlands. The network monitors soil moisture in the unsaturated zone for different soil textures and land covers present in the area, and it covers the topographic gradient of the region. At each location we installed Decagon 5TM sensors at depths of 5 cm, 10 cm, 20 cm, 40 cm and 80 cm. The logging time interval is set on 15 minutes. The Raam network is operational since April 2016 and the measurements are on-going.
    The effect of fiber and prebiotics on children’s gastrointestinal disorders and microbiome

    children - dietary fiber - functional gastrointestinal disorders - Gut microbiota - oligosaccharides - prebiotics

    Introduction: The bacteria received upon birth are the start of colonization of the approximately 1014 bacteria that are present in the mature human gastrointestinal tract, better known as the microbiota. The gut microbiota is implicated in gastrointestinal health, nutrient metabolism and benefits such as prevention of infection. Dietary fiber, including prebiotics, escape digestion in the small intestine and reach the colon intact, where they are partially or completely fermented by the gut microbiota. Areas covered: The possible interactions between dietary fiber, prebiotics and microbiota are discussed as well as how this relates to functional gastrointestinal disorders. During the first years of life the microbiota have not yet reached a stable state and is sensitive to disturbance by environmental factors. An imbalance in the microbiota early in life is found to be associated with several functional gastrointestinal disorders such as colic, functional abdominal pain, irritable bowel syndrome and constipation. Expert commentary: A better understanding of how gut microbial changes in early-life can impact gastrointestinal health might lead to new treatments or disease prevention. Nutritional strategies with fiber or prebiotics may support health due to modification of colonic microbiota composition and metabolic activity, for example by growth stimulation of Bifidobacterium and Lactobacillus.

    Nederlandse handel in snijbloemen
    Jukema, G.D. ; Benninga, J. - \ 2017
    Wageningen University & Research - 4
    De handelsbalans voor 2016 laat een gunstige ontwikkeling zien voor snijbloemen. Een hogere procentuele stijging van de export, inclusief wederuitvoer, (8%) dan de import (5%) ten opzichte van 2015 zorgt voor een toename van het saldo op de handelsbalans. Nederland blijft een belangrijk land voor de afzet van bloemen uit andere landen. Nederland exporteert vooral snijbloemen naar Duitsland, het Verenigd Koninkrijk (VK) en Frankrijk. De import van snijbloemen in Duitsland is vooral afkomstig uit Nederland. Kenia is op gepaste afstand tweede herkomstland op de Duitse markt.
