    The world is witnessing a period in its history when the increasing socio-political upheavals are taking the lives of thousands, and destroying the natural wealth of our planet. Poverty and food insecurity are two key forces driving this destruction. These ongoing problems compound those already being posed by an increasing shortage of water, scarcity of productive land, an expanding population, and the threat of global warming.

    The paper proposes the use of meta models to determine the optimal intertemporal management of soil and phosphorus losses from agricultural land. This approach allows finding a equilibrium of the economic and biophysical system simultaneously. In contrast to the existing literature the model takes account of nonlinear relationships and of a large number of agricultural activities. The mathematical problems arising from this complex setup are addressed and the model is solved numerically.

    The purpose of this paper has been to present quality-adjusted values for land in the United States and nine European countries using price and quantity data for 1990. Disregarding such differences in the quality-adjusted land input would generate biased estimates of the land input and thus of total factor productivity. Land quality adjustments could potentially be enhanced further with additional data on soil characteristics, climate, and other productivity-related characteristics.

    In this paper we develop a dynamic data-consistent way for estimating agricultural land use choices at a disaggregate level (district-level), using more aggregate data (regional-level). The disaggregation procedure requires two steps. The first step consists in specifying and estimating a dynamic model of land use at the regional level. In the second step, we disaggregate outcomes of the aggregate model using maximum entropy (ME). The ME disaggregation procedure is applied to a sample of California data.

    This work looks into the potential use of various instruments which rely on a close interaction between different segments of society (the public, the private and the third sectors) for increasing low income urban land development in Brazil. It is based on the recognition that the Brazilian housing problem is serious, threatening the development and environment of urban centres in the country, being also intimately related to the difficult access to adequate land by a significant portion of the urban population.

    In de Eerste nota voor de ruimtelijke ordening werd het instellen van bufferstroken of bufferzones tussen stadsagglomeraties in de Randstad aangekondigd met als doel de openheid daartussen te handhaven. Bereikbaarheid van het buitengebied voor recreatie was ook een belangrijk motief. Strategische grondaankopen hoorden erbij. Later groeide het besef om in deze bufferzones ook nutsfuncties te realiseren om de kwaliteit te vergroten, zoals bos, natuur, recreatiegebieden en bedrijfsvergroting van landbouwbedrijven met het oog op het landschapsbehoud. Veel gronden werden aangekocht door BBL.

    Het gebied Kromme Rijn bestaat uit holocene rivierkleiafzettingen. Alle afzettingen die aan of nabij het oppervlak voorkomen worden tot de Betuwe Formatie gerekend. Ze zijn afgezet door de verschillende stroomgordelverleggingen van de Rijn. Het gebied bestaat voor een belangrijk deel uit hooggelegen stroomruggronden (ooivaaggronden en poldervaaggronden). Ze bestaan uit zavel en lichte klei; binnen 120 cm - mv. komt veelvuldig fijn en/of grof rivierzand voor. Verspreid door het gebied komen komkleigronden (poldervaaggronden) voor. Ze bestaan voornamelijk uit kalkloze, zware (kom)klei.
