Landbrugsvidenskab

Jorden er grundlaget for vores fødevareproduktion og fødevaresikkerhed. Den er hjem for mere end en fjerdedel af klodens biodiversitet og fungerer som planetens største vandfilter. FN har anslået, at hvis udpiningen af jorden fortsætter, vil mere end 90 % af klodens jorder være svært udpinte i 2050. Regenerativt landbrug er blevet beskrevet som en jordbrugsrevolution, der har potentialet til at vende denne udvikling ved at genopbygge jordfrugtbarheden og øge kulstofbindingen i jorden. Her præsenteres for første gang en række centrale skikkelser i den regenerative jordbrugsbevægelse i Danmark i en samtalebog, der giver et indblik i jordbrugernes arbejde og formidler et grundlæggende skifte i vores forståelse af, hvad jord overhovedet er.Sofie Isager Ahl (f. 1988) er forfatter og har skrevet ph.d. i antropologi om regenerativt landbrug. Hun har tidligere udgivet de skønlitterære bøger Naboplanter (2018) og Demeters latter (2022). I 2023 udkom den etnografiske monografi Regeneration, der tegner et portræt af en ny bevægelse af regenerative jordbrugere i Skandinavien.Sille Skovgaard (f. 1989) er uddannet økologisk jordbruger og antropolog med speciale i regenerativt landbrug. Hun har lavet filmen Jeg tror, vi starter som lys (med Emma Harris, 2024) om regenerative jordbrugeres eksperimenter med jordfrugtbarhed og sidder i bestyrelsen for foreningen Andelsgaarde.

I bogen skildrer Den Grønne Ungdoms­bevægelse en fremtids­vision for et jord­forbundet og retfærdigt ­land­brug og præsenterer de ­konkrete politiske tiltag, der kan føre os dertil. Et utopisk opråb for alt det, vi har at vinde.

Åsmund Bjørnstad er professor emeritus i planteforædling i Norge. I Kornbogen – brødets og øllets historie bygger han på det seneste tiårs indsigter indenfor genomforskning, arkæologi, kulturhistorie og bæredygtighedsforskning.Vi tæmmede kornet, og det os! Åsmund Bjørnstad formidler med kulturhistorisk spændvidde kornenes – det vil sige majsens, risens, hvedens, sorghums, hirsens, havrens og rugens – historie, fra vi begyndte at tæmme de vilde frø - og de tæmmede os. For ti, tolv, fjorten tusind år siden. Gennem denne kultivering opstod skriftsprog, tidsregning, religioner og klassesamfund – og den mangfoldighed af mutationer, som vi dagligt, uafvidende sætter på tallerkenerne. Eller svinger kruset med øl! Korn nok? Det var spørgsmålet for stenalderkvinden, som tæmmede kornet og frem til spørgsmålet ligesom gik i glemmebogen, og så lød det: Kød nok? Men nu er kornet igen kommet på den internationale dagsorden: Korn nok? At hver andet korn i dag går til dyrefoder eller til bioenergi, beskriver den nuværende udvikling. Kan den mon fortsætte – i et ændret klima, i en ny verdensorden? Bogens billedside er i absolut særklasse. Omkring 300 illustrationer rummer bogen.

This book analyses situations of coexistence and confrontation of agricultural and food models according to four major dimensions of territorial development: the tension between specialisation and diversification; innovation; adaptation; and food transition. New agricultural and food models are being deployed in territories around the world in response to criticisms of the old forms of agriculture and food production, and in order to meet new challenges. These models embody archetypes of the observed diversity, actors¿ projects or new norms.A number of conceptual studies and case studies from France and other countries allow us to understand the interactions between these models (confrontation, complementarity, co-evolution, hybridisation, etc.), taking us well beyond the characterisation of their diversity and the evaluation of their relative performances. The coexistence and confrontation of these models build up their capacity for radical change.The book asks original questions about the analytical framework, its methodological challenges and the expected outcomes for the support of agricultural and food development in rural and urban territories. It is intended for researchers, teachers, students and professionals interested in territorial development.Pierre Gasselin, Sylvie Lardon, Claire Cerdan, Salma Loudiyi and Denis Sautier are the scientific coordinators of this book. They are geographers and economists at CIRAD, INRAE and VetAgro Sup, where they conduct research on the transformation of agriculture, food systems and territories in France and other countries. This book is the result of a collective research process involving 36 authors from Argentina, Belgium, Brazil, Burkina Faso, France, Japan, Switzerland and Vietnam.Jan Douwe van der Ploeg, author of the Foreword, is Professor Emeritus of Rural Sociology at Wageningen University & Research in the Netherlands and Associate Professor of Agricultural Sociology at the China Agricultural University in Beijing. He has conducted extensive research on processes of agricultural transition and on dynamics of rural development.

Phosphorus (P) stands second to nitrogen in terms of its essentiality as a plant macronutrient, as well as due to its involvement in almost all plant developmental stages, primary and secondary plant metabolisms, maintenance of membrane structures, and in the structural skeleton of major biomolecules. An optimum P-supply also helps plants combat abiotic stress impacts. Most P in soil remains unavailable for uptake by plants. P-containing fertilizers are being added to agricultural lands to sustain high yields. Only the least amount of the applied P (20%¿30%) is used by most cultivated plants, and the rest remains as legacy P (P surpluses), which eventually causes eutrophication. This book, Phosphorus in Soils and Plants, reviews P in soils and plants, P dynamics in the soil¿water¿sediment environment, the major roles of P in the photosynthetic dark phase-biochemical pathways, major approaches for the sustainable management of P in agriculture, main mechanisms underlying the role of P in the regulation of plant¿microbe interactions in the rhizosphere, literature on the role of microbial phosphate solubilization in management of soil and plant nutrients, and insights into P recovery through waste transformation. This volume is an important resource for plant biologists involved in teaching or research who wish to advance their knowledge of P in soils and plants.

This book focuses solely on the issues of agricultural productivity analysis with advanced modeling approaches bringing solutions to food-insecure regions of the world, especially in south and southeast Asia and in Africa. Advanced modeling tools and their use in regional planning provide an outstanding opportunity to help face the challenges of climate change. The sudden effect of flash floods, drought, salinity, and sea water rises causing saltwater intrusions and its impact on agricultural production are some of the disastrous results of climate change.In this edited volume, information on climate-induced impacts for flooding, flash floods, and drought impact on agricultural crops is provided to address possible solutions for food security in south Asia, southeast Asia, and some regions of Africa. Leading-edge research methodology is presented as it relates to remote sensing applications for regional science and allied fields. In regional policy planning, agriculture andforestry play key roles in food security along with environmental conservation and depend on geo-spatial variability. Satellite remote sensing and geographical information systems have an immense potential to encompass all these factors and to catalogue the regional variability of climate change and climate economics. In the satellite remote sensing domain, advanced modeling tools, deep learning applications, and cloud-based earth engines significantly increase the flexibility of decision making and its application for regional perspectives. The result can increase agricultural and forest productivity and ensure its resilience and sustainability.The book¿s chapters introduce modeling techniques such as machine learning and fuzzy expert system using satellite remote sensing datasets based on cloud application. These methods assist regional planners to increase crop production, land use, and detection of changes in land cover in order to better understand their vulnerability toclimate-related disaster. Furthermore, remote sensing and in-depth GIS analysis are integrated with machine learning to address natural uncertainties such as flash floods, droughts, and cyclones so that emergency responses for agricultural production management can be adopted more effectively.

This book examines policy responses to food waste and loss, an issue of significant, global concern, with one-third of food produced for human consumption lost or wasted.

This book combines chapters emphasising mathematical, statistical, and computational modelling applied to insect populations, particularly pests or natural enemies in agricultural landscapes. There is a gap between agricultural pest experimentation and ecological theory, which requires a connection to supply models with laboratory, and field estimates and projects receiving inputs and insights from models. In addition, decision-making in entomology with respect to pest management and biological conservation of natural enemies has been supported by results obtained from different computational and mathematical approaches. This book brings contemporary issues related to optimization in spatially structured landscapes, insect movement, stability analysis, game theory, machine learning, computer vision, Bayesian modelling, as well as other frameworks.

Sandy soils cover approximately 900 million ha worldwide, and there are extensive areas of sandy soils under cultivation. Most sandy soils have high water permeability, low water-holding capacity, low ability to retain and exchange nutrients, weakly developed soil structure and they may be prone to erosion by wind. As irrigation is required for obtaining good crop yields, there is a risk of substantial leaching of nutrients and pesticides, and ground water depletion. Due to global pressure on land resources, marginal soils such as sandy soils are taken into production or cultivated more intensely. Sandy soils ¿ as a group of soils with specific characteristics and ecological limitations ¿ have received limited research attention. This books presents the main papers from the Global Conference on Sandy Soils which was held in June 2023 in Madison, USA. This book focuses on novel and exciting aspects of research on sandy soils which is presented into three sections: Distributionand Assessment, Soil Carbon and Soil Health, and Water and the Environment. It presents a global glimpse on what recent progress has been in the study of sandy soil and their properties and management.
