    In Indonesia, land cover change for agriculture and mining is threatening tropical forests, biodiversity and ecosystem services. However, land cover change is highly dynamic and complex and varies over time and space. In this study, we combined Landsat-based land cover (change) mapping, pixel-to-pixel cross tabulations and expert knowledge to analyze land cover change and forest loss in the West Kutai and Mahakam Ulu districts in East Kalimantan from 1990-2009.

    The increasing expansion of cropland is major driver of global carbon emissions and biodiversity loss. However, predicting plausible future global distributions of croplands remains challenging. Here, we show that, in general, existing global data aligned with classical economic theories of expansion explain the current (1992) global extent of cropland reasonably well, but not recent expansion (1992–2015).

    Deforestation and drought are among the greatest environmental pressures on the Amazon rainforest, possibly destabilizing the forest-climate system. Deforestation in the Amazon reduces rainfall regionally, while this deforestation itself has been reported to be facilitated by droughts. Here we quantify the interactions between drought and deforestation spatially across the Amazon during the early 21st century.

    Land suitability analysis is employed to evaluate the appropriateness of land for a particular purpose whilst integrating both qualitative and quantitative inputs, which can be continuous in nature. However, in agricultural modelling there is often a disregard of this contiguous aspect. Therefore, some parametric procedures for suitability analysis compartmentalise units into defined membership classes. This imposition of crisp boundaries neglects the continuous formations found throughout nature and overlooks differences and inherent uncertainties found in the modelling.

    Large areas of agricultural land have been abandoned in European Russia since 1991, triggering succession toward more wooded landscapes, especially in northern regions where conditions for agriculture are more challenging. We hypothesize that this process has contributed to a southward shift by migratory Atlantic Greater White-fronted geese, as stopover sites in northern Russia became progressively less suitable. To test this hypothesis, we located stopover sites from information contained in 2976 ring recoveries and sightings of neck-collared geese.

    Deze publicatie gaat over de toekomst van natuur in het landinrichtingsgebied Losser en is een van de achtergronddocumenten die in opdracht van de Dienst Landelijk Gebied zijn opgesteld, waarin het behoud en herstel van natuur- en landschapswaarden ende realisatie van de ecologische hoofdstructuur (EHS) centraal staan. Hierbij is de rol voor de terreinbeherende organisaties alhier - Staatsbosbeheer, Natuurmonumenten, Stichting Edwina van Heek en Landschap Overijssel - van groot belang.

    In 1997 is het rapport van het Staring Centrum 'Meten van Maatwerk: monitoring van het WCL-beleid 1994-1996' uitgebracht. De conclusie uit dit rapport was dat er nogal wat verschillen zijn tussen WCL-gebieden als er gekeken wordt naar sturing en het aantal projecten dat is gestart. Door gebruik te maken van kennis over marketing en samenwerking zou de sturing en integraliteit van de reeds lopende initiatieven uitgebreid kunnen worden. Het onderzoek richt zich op het pilotgebied 'de Meierij' en de daarbij betrokken actoren.
