"Smallholder farms or smallholdings comprise livestock and livestock, livestock and crops and crops and crops farming systems. It involves nutritional inter-relationships of integration and interdependency between livestock and crop systems and crop and crop systems. There are an estimated 500 billion smallholder farms worldwide supporting livelihoods of about 2 billion people, most of who are in Sub-Sahara Africa and Asia. Smallholders make more than 60% of agricultural producers supplying local and international food markets, and employ about 70% of farming communities in Sub-Sahara Africa and Asia. However, these farming systems experience financial, technological, infrastructural, market access, environmental and policy and institutional framework challenges. Considering the importance of smallholder farming systems, attempts should be geared towards mitigating the challenges and promoting productivity and sustainability of these farming systems. This is expected to lead to improved food and nutrition security and food safety and translate to improved livelihoods of smallholder farmers and increased income from agriculture products. The authors' of this book focus on the challenges and opportunities of smallholders and smallholding systems all over the world"--

This book provides examples of pollutants, such as accidental oil spills and non-degradable plastic debris, which affect marine organisms of all taxa. Terrestrial runoff washes large amounts of dissolved organic materials from agriculture and industry, toxic heavy metals, pharmaceuticals, and persistent organic pollutants which end up into rivers, coastal habitats, and open waters. While this book is not intended to encyclopaedically list all kinds of pollution, it rather exemplifies the problems by concentrating on a number of serious and prominent recent developments. The chapters in this book also discuss measures to decrease and remove aquatic pollution to mitigate the stress on aquatic organisms. Aquatic ecosystems provide a wide range of ecological and economical services. In addition to providing a large share of the staple diet for a fast growing human population, oceans absorb most of the anthropogenically emitted carbon dioxide and mitigate climate change. As well as rising temperatures and ocean acidification, pollution poses increasing problems for aquatic ecosystems and organisms reducing its functioning and services which are exposed to a plethora of stress factors.

Cet ouvrage examine les pratiques journalistiques qui ont caractérisé la couverture médiatique du conflit armé ayant opposé les Forces armées de la RDC à la rébellion du Mouvement du 23 mars (M23) dans la province du Nord Kivu. L'auteur scrute le positionnement des journalistes des radios congolaises et étrangères face aux discours et actions déployés par les protagonistes du conflit en vue d'exercer un contrôle absolu sur la production et la diffusion de l'information. Pas moins de trente heures d'informations diffusées sur cinq radios (Kivu One et VBR de Goma, Top Congo FM et Radio Okapi de Kinshasa, RFI émettant depuis Paris) sont confrontées aux discours de dix-neuf journalistes présents sur le terrain lors des événements. Cette confrontation éclaire sur l'incidence des conditions de production dans la construction des récits produits. L'ouvrage met en lumière un ensemble des stratégies passionnantes déployées par les journalistes pour contourner les pressions et tenir leurs engagements de quatrième pouvoir
