Executive Summary Increasing global demand for food and the need to address climate change risk make it ever more urgent to both protect ecosystems and use land more productively and efficiently. Brazil is a key player in this context and has made significant gains in recent decades. Between 1970 and 2006, its average national cattle farm productivity doubled and its average national crop farm ...

This paper aims to introduce and discuss six challenges and issues facing the development of SDIs which will be able to meet the sustainable development objectives of society. These issues and challenges include: SDI to facilitate spatially enabled government Role of government, private and academic sectors Development of SDI vision, mission and road map – where are we heading? SDI to facilitat...

Title of Dissertation: THREE ESSAYS ON NON-BALANCED ECONOMIC GROWTH, ECONOMIC GEOGRAPHY, AND THE REGULATION OF PUBLIC LAND IN THE UNITED STATES Michael H. Taylor, Doctor of Philosophy, 2014 Dissertation directed by: Professor Robert G. Chambers Department of Agricultural and Resource Economics This dissertation is comprised of three essays. The first essay, "The Spatial Consequences of Non-Bala...

This paper summarizes the literature on spatial filtering for analysis of spatial data, as proposed by Griffith (2000a). Given the scarcity of its application in transportation and its fledgling nature, preliminary case studies were conducted using continuous and discrete response data sets, for land values and land use, in comparison with results from spatial autoregressive models with distanc...

Land registration and cadastral systems exist in great variety. This paper describes the rich history of Zambian land tenure systems and discusses the present land tenure system. Zambia has a dual land tenure system: customary tenure and formal title registration. In the customary system the chiefs regulate the allocation of the land. They rule with the consent of their people. This system is c...

Post World War II suburban growth in Canada and the US has created concern over the long-term availability of farmland to meet food production needs. Subsequent efforts to provide legal protection to agricultural land continue to shape the development of the fringes of nearby urban areas. This paper employs the concept of “agriburbia,” suburban landscapes in which agriculture maintains a signif...

Together with rapid development in GI science recent decades, the fractal geometry represents a powerful tool for various geographic analyses and studies. This study points the land-cover areas with extreme values of fractal dimension in Olomouc region. This leads, together with consequent statistical analyses, to result that according to fractal dimension it is possible to distinguish (or at l...

Many remote sensing applications require not only the land cover of extracted objects but also shape parameters of and structural relationships between areas of speciic landcover. Conventional sensors such as Landsat TM ooer suucient spectral resolution for land cover classiication. Their pixel size, however, is relatively high in relation to the observed objects, leading to a high percentage o...

Given an agricultural watershed containing a set of spatial units, and a set of land management practices, the Geodesign Optimization (GOP) aims to find a land management practice for each spatial unit that optimizes overall water quality improvements in the watershed under both budget constraint and spatial constraints (e.g., minimum contiguous area, shape) arising from farm equipment operatio...

Look at a plant, and you’re probably also looking at a fungus. More than 80% of land plants partner with fungi to help those plants extract nutrients—nitrogen and phosphorus—from the ground (1, 2). The plants return the favor with carbon from their photosynthesis. Biologists suspect that this partnership was a major factor in allowing plants to move from water to land about 470 million years ag...
