    This document presents the results of a search for policies and conditions that can help accelerate agricultural development in Africa. This development has been limited in many countries, as evinced by extreme low fertilizer use, low crop yields, poverty and high food insecurity. The rate of development is quantitatively described for the period 1961–2014 for almost fifty countries, those of the African mainland plus Madagascar, on the basis of data on the average cereal yield and fertilizer use. The way the rainfall impacts on the fertilizer-yield relationship has been studied, by comparing contrasting rainfall transects in Western and Southern Africa, occupied by respectively 19 and 9 countries. On the basis of data from the period 1981–2014, it is shown that soil fertility dominated over rainfall in determining crop yields. Data on the evolution of cereal yield rates over the entire 1961–2014 period have been used for dividing the 49 countries into two main groups, subdivided into four and two classes. In the first group of countries, the yields per hectare increased, in different degrees. The second group includes one class of countries with stagnating yields since 1961, and one that at present has lower yields than in 1961. Here, any increase in food production has come from area expansion. All countries have been categorized on the basis of socio-economic as well as agro-ecological conditions. The comparison of classes enables the identification of stimuli and obstacles for agricultural development. The role of policies for change has been studied as well, with a view to identifying policies that can help accelerate agricultural development in Africa. The dominance of poor soils, often combined with difficult climates, explains in part why agricultural development has been slow. In many places, the low average natural production conditions have resulted in a population density that is much too low to allow for a financially beneficial use of fertilizer and other external agricultural inputs. The high costs of transport and trade, and of food and labor, have seriously hindered agricultural development in many African countries. Market oriented production, for the national or the international market, did not become the driver for development, in contrast to countries with more suitable climates and better soils. A hopeful tendency emerges from this study: African agricultural development is taking off in response to population growth, as is shown by the cereal yield and fertilizer use adoption trends in many countries. Three quarters of the African population lives in countries with positive yield growth rates, with some of them having reached Green Revolution growth rates. Policies and conditions are presented that enable accelerated yield growth, which is a matter of life and death for the last quarter of the population, which lives in countries with no significant or negative yield growth rates, but is also of vital importance for

    Er zijn fundamentele transities in onze economie en samenleving nodig om de teloorgang van natuur te stoppen, constateerde het IPBES eerder dit jaar. De huidige aanpak van het natuurbeleid richt zich onvoldoende op de oorzaken van biodiversiteitsverlies. Ook in Nederland blijkt de huidige praktijk van natuurbescherming niet afdoende om de doelen te realiseren. In de Natuurverkenning 2020 verkennen we hoe zulke transities eruit zouden kunnen zien en welke potenties ze hebben.

    biodiversity - Central Africa - COI - freshwater - ichthyofauna - taxonomy

    The Congolese and Lower Guinean ichthyological provinces are understudied hotspots of the global fish diversity. Here, we barcoded 741 specimens from the Lower and Middle Congo River and from three major drainage basins of the Lower Guinean ichthyological province, Kouilou-Niari, Nyanga and Ogowe. We identified 194 morphospecies belonging to 82 genera and 25 families. Most morphospecies (92.8%) corresponded to distinct clusters of DNA barcodes. Of the four morphospecies present in both neighbouring ichthyological provinces, only one showed DNA barcode divergence <2.5%. A small fraction of the fishes barcoded here (12.9% of the morphospecies and 16.1% of the barcode clusters representing putative species) were also barcoded in a previous large-scale DNA analysis of freshwater fishes of the Lower Congo published in 2011 (191 specimens, 102 morphospecies). We compared species assignments before and after taxonomic updates and across studies performed by independent research teams and observed that most cases of inconsistent species assignments were due to unknown diversity (undescribed species and unknown intraspecific variation). Our results report more than 17 putative new species and show that DNA barcode data provide a measure of genetic variability that facilitates the inventory of underexplored ichthyofaunae. However, taxonomic scrutiny, associated with revisions and new species descriptions, is indispensable to delimit species and build a coherent reference library.

    Nederland staat voor een aantal grote uitdagingen op het gebied van het waterbeheer, dat heeft de zomer van 2018 nog maar eens extra duidelijk gemaakt. Omdat het klimaat verandert krijgen we vaker te maken met extreme neerslag en langdurige perioden van droogte. Dit heeft direct consequenties voor onder andere de waterkwaliteit en de waterkwantiteit. Op de hoger gelegen zandgronden in Nederland zijn deze consequenties zo mogelijk nog groter omdat hier de mogelijkheden om water tijdelijk te bergen of van elders aan te voeren vaak veel beperkter zijn.

    Natuur 2.0 : Het natuurdebat op social media

    Social media are playing an increasingly important role in public debate. The aim of this analysis is to get a clear picture of how the subject of nature is represented on social media and how this affects the public debate on nature in the Netherlands. A range of software was used to collect social media posts about nature. These posts were then analysed using a combination of quantitative and qualitative methods at different levels (macro, meso, micro). The results show that nature is a live issue online and that it generally has positive connotations. At the same time, the confluence of different ideas about what nature really is can sometimes lead to heated discussions and a polarised debate. For a long time now the influence of this digital debate has extended beyond the online domain into the world of practical conservation management and nature policy.
    Hoe het uit de hand liep in de Oostvaardersplassen
    Breman, B.C. - \ 2018

    Het natuurgebied de Oostvaardersplassen was de afgelopen maanden het toneel voor protest tegen het beleid van Staatsbosbeheer. En daarbij liepen de emoties hoog.

    De protesten houden aan en inmiddels zijn de toegangswegen tot het gebied met betonblokken afgesloten. Daarmee wil Staatsbosbeheer actievoerders tegenhouden die dit weekend dieren met paardentrailers uit het gebied willen ophalen.

    Sociale media spelen een belangrijke rol bij de protesten en wetenschappers van de Universiteit Wageningen hebben de discussie daar geanalyseerd. Wij praten erover met Bas Breman, onderzoeker natuurbeelden en natuursentiment aan de Universiteit Wageningen

    Afgelopen winter leidde de sterfte van wilde dieren in de Oostvaardersplassen tot een heftige maatschappelijke discussie. Nu de media-aandacht wegebt blijft er een aantal prangende vragen liggen voor wildbeheer en natuurbeleid. Hoe kon deze maatschappelijke discussie zo polariseren en resulteren in een aanpassing van het beleid? Sociale media geeft inzicht in het verloop van de discussie.
