Reducing the use of pesticides by early visual detection of diseases in precision agriculture is important. Because of the color similarity between potato-plant diseases, narrow band hyper-spectral imaging is required. Payload constraints on unmanned aerial vehicles require reduc- tion of spectral bands. …

The loss of biodiversity is a worldwide problem caused by over exploitation of natural resources, pollution, introduction of invasive species and other problems, human induced. The Netherlands is working on strengthening its natural environment boosting social and economic wellbeing. In Southwest Drenthe, …

Many of the world’s forest have been destroyed and degraded, and the Atlantic Rainforest inBrazil is no exception, having its forest cover reduced to 8% of its original size by agriculturalexpansion and natural resource exploitation. Efforts to mitigate deforestation involve reforestation of abandoned …

The Compassberg Protected Environment (CPE) in South-Africa suffers severely from erosion in the form of gullies. Herbivory, bare soil, little water capture and lack of vegetation are the most important factors that contribute to erosion in the CPE. Grazing lawns are a vegetation type that is only found …

Because local weather conditions in moderate climates are changing constantly, heat transfer specifications of substrate and vegetation in vegetated green roofs also change accordingly. Nevertheless, it is assumed that vegetated green roofs can have a positive effect on the thermal performance of construction …

Heathland, with its frail character, has always been one of the most essential habitats for almost all indigenous reptile species in the Netherlands. Situated in the Drents-Friese Wold National Park, the Doldersummerveld ranks as one of the best developed heathland areas of Western Europe and counts …

In het kader van het vraagstuk over kostencompensatie en terugverdienen door efficiënte benutting van biomassa, is binnen het beheertraject van Rijkswaterstaat – Oost een onderzoek uitgevoerd in de uiterwaarden van de IJssel en de Twentekanalen. Centrale vraag vanuit de opdrachtgever is welke locaties …

Aanleiding van het onderzoek is het onbekend zijn van de vegetatietrends en de samenhang met de ontwikkelingen van abiotiek en beheer in het oostelijke gedeelte van de Nieuwe Sliedrechtse Biesbosch sinds de afsluiting van het Haringvliet in 1970. De Louw Simonswaard, Houwelingswater / Sneepkil en Kop …

Kleinschalige overlaten en vispassages bestaande uit houten damplanken, worden op de traditionele methode (intrillen) aangebracht. Mogelijk kunnen deze overlaten en vispassages ook uit prefab elementen vervaardigd worden. Om hierop antwoord te kunnen geven, is onderzoek gedaan naar het materiaalgebruik …

Lyme borreliosis, commonly known as Lyme disease, is a vector-borne disease that is caused by the bacterium Borrelia burgdorferi sensu lato. Infected ticks can transmit this disease and infect humans. Decreasing human Lyme infections could be achieved by vegetation control , since mortality and questing …
