The debate on “sustainable development”, ecosocialism, agroecology and the production of healthy food is increasing in Europe and in the world.
This book depicts peasants' struggles for the resistance to the advance of destructive production. It also socializes the results of research, which shows us the pressage of alternative forms of labour, which are based upon agroecology, in cooperation and corporativism besides the emergence of agroecology schools of one of the main social movements of the present time: the Landless Movement.
Interactions between society, biodiversity and water in a humid tropical forest
This book examines interactions between human communities and the global biodiversity that is sheltered by the Salonga National Park. While not being a review of research that has been on-going in the Salonga National Park over several years now, the book takes a bird-eye perspective to look at how the forests, waters and species that occur in the wider Salonga landscape interact to give birth to what the Salonga National Park is. As such, the book treats of the Salonga’s wildlife, its forests and waters, and the Salonga National Park’s contemporary human history, within the regional framework.
Hoe ziet natuurinclusieve landbouw eruit in de praktijk? Wat weten we over de effecten op bodem, water, biodiversiteit en klimaat? Hoe integreer je maatregelen voor een natuurinclusieve bedrijfsvoering? Deze vragen worden beantwoord in dit boek bomvol ervaringen van agrariërs en onderzoekers van CLM Onderzoek en Advies en Louis Bolk Instituut. In samenwerking met Hogeschool van Hall Larenstein en Aeres Warmonderhof is deze ervaring praktijkrijp gemaakt voor het leslokaal.

Dit boek is tot stand gekomen met subsidie van LNV. Het boek komt in maart 2024 digitaal gratis beschikbaar via Groenkennisnet.
Technology for optimal crop production, second edition
'Greenhouse horticulture' is an easy-to-read textbook for all those interested in protected cultivation, from university students and teachers to professional advisers in the field and managers of horticultural companies. Also available as E-book see greenhouse-horticulture-second-edition . For more information about the e-book, please contact Sales.

This book provides an integrated approach to crop growth and development and the technical aspects of greenhouse cultivation and climate management. It combines an analysis of the relationship between crop production and ambient climate with an explanation of the processes that determine the climate in a protected environment. With the ability to modify the environment comes the need for growers to strike a balance between the costs and benefits of technology. This book outlines the methods and gives several examples of how to make 'optimal' choices about technology.
Sustainable management of shoot and root environment is discussed, as well as the pros and cons of vertical farming. The processes addressed in this book, like crop growth, energy balance and mass exchange, apply to any kind of greenhouse. Therefore, in spite of the word 'technology', this is not a book about high-tech greenhouses only.
Life Sciences collection with topics in Animal and Veterinary, Food and Health, Agribusiness and Rural Studies, Agriculture and Environment.

Studying the adoption of precision agriculture (PA) is important to identify future challenges and research questions. Currently, there is no mechanism to monitor and compare PA adoption at the European level. This study addressed this issue and proposed a monitoring mechanism based on remote sensing adoption as a case study. A study was set up in six EU countries (France, Germany, Hungary, Italy, Slovakia, and Spain). More than 170 stakeholders were interviewed. While the adoption rates varied between countries and usages, the results confirmed an increasing application of remote sensing in agriculture.

Fruit size information through the season is an important parameter allowing growers to better manage the orchard. In this study, a Python based computer vision algorithm for sizing apples directly on-the-tree was developed. The system was made of a consumer-grade depth camera and tested at two distances and different timings through the season, in a Fuji apple orchard. The system exploited a YOLOv5 detection algorithm and a trigonometric approach based on depth information to size the fruits. Results showed potential field application even if a further system improvement to reduce the sizing error (RMSE <10 mm) need to be achieved.

Turfgrass irrigation consumes a large amount of the scarce freshwater in semi-arid areas like Utah. As much as 50% of this irrigation water is wasted. It has been suggested that determining patterns of spatial variability in soil moisture to modify applications with new valve-in-head sprinkler technology can greatly reduce waste. Variable rate irrigation (VRI) studies in traditional agricultural settings have shown that VRI zones do not stay static temporally and need to be frequently re-determined. Electrical conductivity (ECa) data from Geonics EM38 surveys and data from RGB and Thermal IR drone surveys are less expensive to collect than field survey data. These methods are compared here for their ability to accurately estimate spatial patterns of volumetric water content (VWC) for determining within-season temporally variable turfgrass VRI zones.

The textural information derived from Sentinel-2 image at the R5 soybean stage was assessed by machine learning algorithms to identify soybean yield variability. Two texture measures (entropy and second-moment angular) calculated over the vegetation indices, spectral bands, and RGB, comprised the best models. The 3-class yield map produced reached an accuracy of 0.81 and a Kappa coefficient of 0.73 using the support vector machine algorithm, which was slightly better than K-nearest neighbors. The 4-class map kept the general shape but lost details and performance. The empirical method proposed shows potential and should be tested over other conditions.

In the present contribution, a comparison between cosmic ray neutron sensing (CRNS) and gammaray spectroscopy (GRS) for soil spatial mapping is shown. The experiments have been conducted in a walnut field situated in Bondeno (Ferrara), Northern Italy, characterized by a relatively strong soil texture spatial variability ranging from sandy to clay soil from north to south. Data acquired were compared to ground portable time domain reflectometry (TDR) observations and regional soil classification maps. Results showed good performance in distinguishing the two main soil type zones. For these reasons, the results support the applicability of these methods: (1) to obtain preliminary maps for specific soil sampling designs; (2) to have a qualitative understanding of soil texture and moisture variability of the field; and (3) to divide the field into sectors with similar hydrological properties. Further experiments and analyses should be undertaken, however, to understand the effect of the different spatial footprints of each detector and the best timing for undertaking the survey.
