ertoe geleid dat in de directe omgeving van steden grote open gebieden onbebouwd zijn gebleven. Bovendien zijn er grote groene recreatiegebieden aangelegd die zeer in trek zijn bij omwonenden. Planologische onduidelijkheid, onvoldoende bestuurlijke regie en, daarmee samenhangend, ontwikkelingen op de grondmarkt hebben ertoe geleid dat de aanleg van groengebieden de afgelopen jaren stagneert. Recentelijk is het rijksbeleid overgedragen aan provincies. Deze hebben echter nog moeite om de integrale ontwikkeling van grote groengebieden in samenhang met rood te regisseren.

Forest science in support to international negotiation on climate change and its local consequences. This article gives an analysis of the major scientific questions underlying the decision making process dealing with forest monitoring under the topic land use, land use change and forestry as a driving force for climate change. It first gives the major scientific findings used as guidelines for political decisions since 1988.

We summarize existing theoretical claims linking poverty to rates of deforestation and then examine this linkage empirically for Costa Rica during the 20th century using an econometric approach that addresses the irreversibilities in deforestation. Our data facilitate an empirical analysis of the implications for deforestation of where the poor live. Without controlling for this, impacts of poverty per se are confounded by richer areas being different from the areas inhabited by the poor, who we expect to find on more marginal lands, for instance less profitable lands.

We review claims about the potential for carbon markets that link both payments for carbon services and poverty levels to ongoing rates of tropical deforestation. We then examine these effects empirically for Costa Rica during the 20th century using an econometric approach that addresses the irreversibilities in deforestation. We find significant effects of the relative returns to forest on deforestation rates. Thus, carbon payments would induce conservation and also carbon sequestration, and if land users were poor could conserve forest while addressing rural poverty.

Geothermal Energy is a natural form of energy stored deep in the earth's hot rocks and
waters within the fractured rocks. It is fairly widespread in the world mostly within
continental plate margins. It has been put into use for several centuries but commercially;
the world's first geothermal power plant was built at Larderello Italy in 1901 and is still
generating. In Africa, Kenya is the first country to utilize this technology for power
generation in the Rift Valley at Olkaria Naivasha. The geothermal energy potential in

Ieder bedrijf produceert afval. Bij bloembollenbedrijven is een groot deel van het afval plantaardig, zoals pelafval, maaisel, stro. Dit afval kan afgevoerd worden. Dat heeft een uitstroom van nutriënten en organische stof van het bedrijf tot gevolg en brengt aanzienlijke kosten met zich mee. Het materiaal kan ook op het eigen bedrijf gecomposteerd worden. Hierdoor worden kosten van afvoer van het materiaal bespaard en kan het materiaal, na compostering, bijdragen aan de organische bemesting van de grond.

Variability in per cell classification accuracy is predominantly modelled with land-cover class as the explanatory variable, i.e. with users' accuracies from the error matrix. Logistic regression models were developed to include other explanatory variables: heterogeneity in the 3x3 window around a cell, the size of the patch and the complexity of the landscape in which a cell is located.

De in dit artikel gepresenteerde lange-termijnvisie geeft een denkbare ontwikkelingsrichting aan, in de lijn van Plan Ooievaar, maar aangepast aan en andere geofysische context (klimaatverandering) en een andere maatschappelijke context (postmoderne)

Although ancestral rights to land are a cornerstone of the livelihoods of indigenous peoples, few countries have been ready to undertake their recognition. Lack of political will together with obstacles such as lack of legal recognition of indigenous rights in national legal frameworks and tenure regimes, different forms of discrimination and inappropriate policies towards indigenous peoples are at the root of some of the limitations that are found with regard to the recognition of indigenous peoples’ land rights.
