Er is veel maatschappelijke draagkracht voor een veerkrachtiger, natuurlijker landbouwsysteem. Boeren willen blijven boeren, burgers willen een betere connectie met de natuurlijke omgeving en consumenten willen een gezondere leefstijl. Biologisch, natuurinclusief, kringlooplandbouw, circulair, agro-ecologie - welk label er ook aangehangen wordt, een integrale aanpak is nodig om deze omslag in de landbouw te kunnen realiseren.00Een goede biodiversiteit is de basis van een gezond agrarisch bedrijf en een gezonde landbouwsector. Die biodiversiteit vormt een essentieel onderdeel van de langetermijnvisie vanuit de overheid die de landbouw in Nederland binnen de kwaliteit van de leefomgeving met oog voor de bodem een lange termijn economisch perspectief biedt. Daarnaast dragen ook burgers, business en consumenten een belangrijke verantwoordelijkheid voor deze omslag.00'Biodivers boeren' brengt deze elementen samen. Het legt de nadruk op de functionaliteit van agro-ecologie, hoe een agrarisch bedrijf baat kan hebben bij verschillende agro-ecologische maatregelen en welke keuzes een boer van nu kan maken en welke ingrepen het overwegen waard zijn. Ook wordt er ingegaan op de maatregelen die alleen de overheid kan nemen, en welke verantwoordelijkheid de agrobusiness, de burger en consument dragen.

Despite its supreme importance and the threat of its global crash, biodiversity remains poorly understood both empirically and theoretically. This ambitious book presents a new, general neutral theory to explain the origin, maintenance, and loss of biodiversity in a biogeographic context. Until now biogeography (the study of the geographic distribution of species) and biodiversity (the study of species richness and relative species abundance) have had largely disjunct intellectual histories. In this book, Stephen Hubbell develops a formal mathematical theory that unifies these two fields. When a speciation process is incorporated into Robert H. MacArthur and Edward O. Wilson's now classical theory of island biogeography, the generalized theory predicts the existence of a universal, dimensionless biodiversity number. In the theory, this fundamental biodiversity number, together with the migration or dispersal rate, completely determines the steady-state distribution of species richness and relative species abundance on local to large geographic spatial scales and short-term to evolutionary time scales. Although neutral, Hubbell's theory is nevertheless able to generate many nonobvious, testable, and remarkably accurate quantitative predictions about biodiversity and biogeography. In many ways Hubbell's theory is the ecological analog to the neutral theory of genetic drift in genetics. The unified neutral theory of biogeography and biodiversity should stimulate research in new theoretical and empirical directions by ecologists, evolutionary biologists, and biogeographers.
