Insects and spidermites do significant damage to vegetable crops in all tropical regions around the world. Today, agro-ecological crop protection methods such as biological control are recommended. This work, a veritable handbook, features 22 references describing the major groups of arthropods: pests and natural enemies (predators and parasitoids). The bio-ecology of these groups and the means at our disposal to control pests are detailed along with many photographs.
This book, in epub format, is the result of 40 years of research on modeling the development and growth of plants. The authors reveal, step by step, the process leading up to the creation of the GreenLab model and the conditions under which it can now be applied.
This book will be available in print and PDF format in June 2017.
This book is a synthesis of twenty years of work under the Loire Grandeur Nature Plan. It describes the current body of knowledge on the functioning of the fluvial-estuary Loire River system, the effects of human activities and efforts made to maintain a lasting balance.
The recycling of organic waste can be considered an agro-ecological practice which enhances soil fertility, reduces environmental impacts and promotes a circular economy. This book gives readers insight into the bio-geochemical processes involved in recycling organic waste and the products derived therefrom. It offers solutions for various social, economic and cultural contexts, North and South.
Fishing from the shore has always been part of maritime culture but the history of its practices and the evolution of its various techniques have not been widely disseminated. This book aims to remedy that deficit. The author explains how man, down through the ages, has engaged in what used to be a subsistence activity and today is a leisure sport. This journey through time shows the creative genius of man and the countless methods he has devised to exploit available resources.
Ranging from the establishment of indicators for urban planning to the measurement of coal stocks and including legal and economic instruments for soil protection, this book from the Gessol programme summarises the latest biotechnical and general knowledge on the subject. It underscores the importance of sustainable land management among global challenges and identifies possible levers of action.
2050. By now you are used to seeing drones flying overhead, both in the city and the countryside: An ambulance drone rushing a defibrillator to a patient, a pollinator drone ... Science fiction? Not really. Drone specialists, coordinated by a scientist, have joined forces with a reporter to give us a glimpse of the future of civilian drone aviation. Learn how these new generation flying machines may gradually make their way into your daily life, and not necessarily in the way you might expect.
The social life of ants has nothing to envy in that of humans: they have managed to conquer the terrestrial world through fascinating behaviour! The unique, adaptive solutions that evolution has devised for ants are revealed here in everyday language and are brought to life by over 150 pictures combining scientific facts with aesthetic charm.
This book, targeting the general public, reveals the beauty of snakes in France and their amazing habits. It illustrates the biological features and morphological diversity of 4 vipers and 9 non-venomous snakes living in metropolitan France. It includes exceptional snapshots: moulting, hunting sequences, hatching, mating combat, playing dead ... The 200 photographs in this book, taken in the wild while respecting their natural habitats, make a plea in support of these magnificent creatures that form part of our biodiversity and natural heritage.
This book presents the biology and habits of wild ducks and also the network of players who interact with them. It invites readers to analyse recent developments in humankind’s relationship with wildlife and nature in general. This book is not intended as a mere natural history of ducks and humankind, but is rather an invitation to make sustainable use of the wild duck population and the natural environment in general in the context of a changing world.
