    Nature loss is a planetary emergency. Humanity has already wiped out 83% of wild mammals and half of all plants and severely altered three-quarters of ice-free land and two-thirds of marine environments. One million species are at risk of extinction in the coming decades – a rate tens to hundreds of times higher than the average over the past 10 million years. The World Economic Forum’s 2020 Global Risks Report ranks biodiversity loss and ecosystem collapse as one of the top five threats humanity will face in the next ten years.

    A feasibility study has been worked out for an integrated advisory system for precision agriculture on the production of forage (grass and maize) for dairy farming in the Netherlands. Technology is not restrictive anymore to apply precision agriculture on important cultivation measures. It is now about achieving an effective integration of sensor data, models, metrics and equipment in a comprehensive advice system. It has been advised how a practical advice system for operational decisions can be realized on the dairy farm in the foreseeable future (

    Measuring, monitoring, and managing biodiversity across agricultural regions depends on methods that can combine high-resolution mapping of landscape patterns with local biodiversity observations. This study explores the potential to monitor biodiversity in agricultural landscapes by linking high-resolution remote sensing with passive acoustic monitoring.

    Human populations and their use of land have reshaped landscapes for thousands of years, creating the anthropogenic biomes (anthromes) that now cover most of the terrestrial biosphere. Here we introduce the first global reconstruction and mapping of anthromes and their changes across the 12,000-year interval from 10,000 BCE to 2015 CE; the Anthromes 12K dataset.

    The restoration of vegetation in abandoned farmlands is an effective approach to control soil erosion on the Chinese Loess Plateau. However, few studies have investigated the effect of natural restoration age on the infiltration patterns and preferential flow in soil layers. This study examined the effect of the temporal variations in the degree of preferential flow and their contribution on the total infiltration in abandoned farmlands restored with different vegetation communities.

    Soil samples in 349  sampling plots were obtained within the LUCAS project in 2009; from these, 205 soil samples were collected in agricultural lands (grasslands, arable lands, grasslands overgrown by trees and shrubs), and 133 soil samples were obtained in forests (deciduous, coniferous and mixed forests), as well as 7 soil samples–in scrublands.

    Although advances in remote sensing have enhanced mapping and monitoring of irrigated areas, producing accurate cropping information through satellite image classification remains elusive due to the complexity of landscapes, changes in reflectance of different land-covers, the remote sensing data selected, and image processing methods used, among others. This study extracted agricultural fields in the former homelands of Venda and Gazankulu in Limpopo Province, South Africa.

    In this study, I tried the understanding of the environment state of the farmland in Fukushima and neighbor prefectures in 2011 to contribute to an evaluation of the radioactive substance pollution of the farmland by the accident of Fukushima daiichi nuclear power plant which occurred with East Japan great earthquake disaster of March 11, 2011 with a satellite remote sensing technology. At first I was done interpretation of the paddy fields approximately one month after the accident by using an optical high resolution satellite image.
