There is a trend to acquire high accuracy land-cover maps using multi-source classification methods, most of which are based on data fusion, especially pixel- or feature-level fusions. A probabilistic graphical model (PGM) approach is proposed in this research for 30 m resolution land-cover mapping with multi-temporal Landsat and MODerate Resolution Imaging Spectroradiometer (MODIS) data. Independent classifiers were applied to two single-date Landsat 8 scenes and the MODIS time-series data, respectively, for probability estimation. A PGM was created for each pixel in Landsat 8 data.
Na representação da realidade, as implicações que o real traz para a ficção vão além da mera imitação. Na Literatura, o modo como se representa a realidade expressa, usualmente, a cosmovisão de uma determinada época. Isso é perceptível no modo realista de composição ficcional, que atinge seu ápice na segunda metade do século XIX, quando “o romance realista autêntico tem assumido a herança da tragédia clássica” (AUERBACH, 2011, p. 446).
It has been argued that the management of land, whether at the field, farm or regional scale, can benefit from computer-based land use system analysis. As a result, a large number of computer-based models and tools have been produced over the past decades with the aim of providing support to policy and management. Though there is still optimism about the potential of land use modelling to contribute to societal problem solving, a number of scholars perceive the impact as too limited.
FAO-Adapt consolidates FAO’s multidisciplinary expertise on climate change adaptation. Through this Organization-wide framework, FAO provides countries with best practices, key principles and priority themes on which member nations can focus adaptation efforts in agriculture and food security. Since launching FAO-Adapt in June 2011, the Organization has: developed and implemented new, adaptation-focused projects and programmes; and enhanced FAO’s own capacity to deliver adaptation support to member countries.
Over fifteen years have elapsed since the transition from the centrally plannedeconomic system started in the early 1990’s. During this time agricultural andrural areas of Central and Eastern Europe have undergone profound structuralchanges with wide variations in the degree of transformation and in the rate ofsuccess in creating a competitive market and private ownership based food andagricultural system. By becoming member of the European Union the "transition"in its traditional interpretation has been concluded in ten of the Central EastEuropean countries.
The main purpose of this paper is to carry out an analysis of the agricultural land market in Poland based on market transactions conducted in 2002. Authors analysed the sale and lease market of agricutural land making an allowance for its ownership structure. The analysis was made both on the private market and toward the land owned by the State Treasury and managed by the Agency of the Agricultural Propety of the State Treasury (since July 16, 2003 transformed into the Agricultural Property Agency).
More irrigated land is devoted to rice than to any other crop. A method to save water in irrigated rice cultivation is the intermittent drying of the rice fields, known as alternate wet/dry irrigation (AWDI). This report reviews previous studies in AWDI, with a focus on mosquito vector control, water saving, and rice yields. Examples are provided from a number of countries.
