Download or read book Agricultural Monitoring in Regional Scale Using Clustering on Satellite Image Time Series written by Renata Ribeiro and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The remote sensing images are more accessible nowadays and there are proper technologies to receive, distribute, manipulate and process long satellite image time series that can be used to improve traditional methods for harvest monitoring and forecasting. The potential of the satellite multi-temporal images to support research of agricultural monitoring has increased according to improvements in technological development, especially in analysis of large volume of data available for knowledge discovery. In Brazil, sugarcane is cultivated on extensive fields and is the main agriculture crop used to produce ethanol. The main objective of this chapter is to monitor the sugarcane crop by clustering analysis with multi-temporal satellite images having low spatial resolution. A large database of this kind of image and specific software were used to perform the image pre-processing phase, extract time series, apply clustering method and enable the data visualization on several steps during the whole analysis process. According to the analysis done, our methodology allows to identify land areas with similar development patterns, also considering different growing seasons for the crops, covering monthly and annual periods. Results confirm that satellite images of low spatial resolution can indeed be satisfactorily used in agricultural crop monitoring in regional scale.

Book excerpt: In a rapidly changing world, there is an ever-increasing need to monitor the Earth’s resources and manage it sustainably for future generations. Earth observation from satellites is critical to provide information required for informed and timely decision making in this regard. Satellite-based earth observation has advanced rapidly over the last 50 years, and there is a plethora of satellite sensors imaging the Earth at finer spatial and spectral resolutions as well as high temporal resolutions. The amount of data available for any single location on the Earth is now at the petabyte-scale. An ever-increasing capacity and computing power is needed to handle such large datasets. The Google Earth Engine (GEE) is a cloud-based computing platform that was established by Google to support such data processing. This facility allows for the storage, processing and analysis of spatial data using centralized high-power computing resources, allowing scientists, researchers, hobbyists and anyone else interested in such fields to mine this data and understand the changes occurring on the Earth’s surface. This book presents research that applies the Google Earth Engine in mining, storing, retrieving and processing spatial data for a variety of applications that include vegetation monitoring, cropland mapping, ecosystem assessment, and gross primary productivity, among others. Datasets used range from coarse spatial resolution data, such as MODIS, to medium resolution datasets (Worldview -2), and the studies cover the entire globe at varying spatial and temporal scales.

Download or read book The State of Food Security and Nutrition in the World 2020 written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2020-07-01 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions. The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic. The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition.

Download or read book Land Cover and Land Use Changes in Eastern Europe after the Collapse of the Soviet Union in 1991 written by Garik Gutman and published by Springer. This book was released on 2016-11-14 with total page 250 pages. Available in PDF, EPUB and Kindle. Book excerpt: This work analyzes the effects of one of the most dramatic changes of entire societies that the world has ever witnessed. It explores the collapse of socialist governance and management systems on land cover and land use in various parts of Eastern Europe. As readers will discover, this involved rapid and unprecedented changes such as widespread agricultural abandonment. Changes in the countries of the former Soviet block, former Soviet Union republics, and European Russia are compared and contrasted. Contributing authors cover topics such as the carbon cycle and the environment, effects of institutional changes on urban centers and agriculture, as well as changes in wildlife populations. The volume includes analysis of the drivers of agricultural land abandonment, forest changes in Black Sea region, an extreme drought event of 2010, impacts of fires on air quality and other land-cover/land-use issues in Eastern Europe. Satellite data used were mostly from optical sensors including night lights observations, with both coarse and medium spatial resolution. Ultimately, this work highlights the importance of understanding socioeconomic shocks: that is, those brief periods during which societies change rapidly resulting in significant impact on land use and the environment. Thus it shows that change is often abrupt rather than gradual and thereby much harder to predict. This book is a truly international and interdisciplinary effort, written by a team of scientists from the USA, Europe, and Russia. It will be of interest to a broad range of scientists at all levels within natural and social sciences, including those studying recent and ongoing changes in Europe. In particular, it will appeal to geographers, environmental scientists, remote sensing specialists, social scientists and agricultural scientists.
