This book was released on 2008 with total page 186 pages. Available in PDF, EPUB and Kindle. Book excerpt: En Afrique de l'Ouest, une série de facteurs contribue à la baisse de la productivité agricole : la dégradation de l'environnement, la forte croissance démographique, les attaques acridiennes, la performance insuffisante des économies. De nombreux pays enregistrent d'énormes déficits alimentaires. Une telle situation ne peut être améliorée qu'à partir de l'adoption de nouvelles technologies visant à l'obtention de meilleurs rendements. Dans cet ouvrage organisé en quatre chapitres, les auteurs se penchent sur les déterminants d'une meilleure productivité agricole. L'accent est surtout mis sur les aléas climatiques de ces dernières décennies, marquées par de fortes irrégularités saisonnières et une baisse régulière de la pluviométrie. Aux aléas climatiques s'ajoute le problème de la fertilité des sols caractérisé le plus souvent par un faible taux de matières organiques : carence en phosphore et en azote, complexe absorbant insuffisant, petite capacité de rétention en eau, etc. Enfin, dans les régions à forte densité de population ( exemples du Ghana et du Togo ), le taux de croissance démographique élevé agit négativement sur le potentiel foncier, caractérisé par la dégradation des ressources naturelles. Les auteurs exposent ici les réalités de ces facteurs déterminants pour la sécurité alimentaire, afin de permettre aux décideurs de mieux les intégrer à leur politique de développement du secteur agricole.

Book Synopsis Animal production and natural resources utilisation in the Mediterranean mountain areas by : A. Georgoudis
Download or read book Animal production and natural resources utilisation in the Mediterranean mountain areas written by A. Georgoudis and published by BRILL. This book was released on 2023-08-28 with total page 640 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mediterranean inhabitants depend on natural resources for their livelihoods. Livestock production and forestry are key sources of income yet are carried out under harsh conditions such as limited land resources, marginal agricultural conditions, isolation, and scant equipment and infrastructure. Livestock is of particular importance in mountain production systems as they convert plant biomass into useful products for humans such as milk, meat and draught power. These products are key to the regions' sustainability. The main topics discussed in this book are: Human geography of Mediterranean mountain territories. Livestock production and natural resources. Improving the efficiency of livestock systems in Mediterranean mountain areas. Applications of new technologies for environmentally sound management of livestock and natural resources. The role livestock plays in rural development and in safeguarding natural resources.

Book Synopsis Agricultural Adaptation to Climate Change by : Christopher R. Bryant
Download or read book Agricultural Adaptation to Climate Change written by Christopher R. Bryant and published by Springer. This book was released on 2016-08-26 with total page 240 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book deals with one of the major challenges facing human society and its governments, climate change and variability. The principal objective of the book is to explore how agricultural production through the actions primarily of farmers, including peasant farmers, adapt to these changing circumstances, what the limitations of adaptation are, how the process of adaptation varies between different territories (e.g. developed countries versus developing countries), and what are or can be the most effective roles for actors other than the farmers, including different levels of government and non-governmental organizations (NGOs) such as professional associations of farmers and community organizations. The principal argument is threefold: 1) while there are significant differences between territories and countries in terms of the capacity of farmers (and the other actors) to engage in capacity building to be able to adapt effectively to climate change and variability, 2) the critical roles are those played out by the farmers themselves, but that 3) other actors can play an important role in accompanying farmers in their adaptation process, providing relevant and strategic information, counseling them and facilitating networking and meetings when appropriate. This effectively means that without engaging in the local adaptation processes governments can really only play effective roles by working with other actors at the local and regional levels. When it occurs, it can be very effective, but when it does not, farmers are left to their own devices (and even then, many are able to use their own creativity and local knowledge to survive and continue to develop). Essentially therefore, the secondary argument that is followed throughout the book is that adaptation is essentially a social process that requires an understanding of social processes and dynamics in each farming community and territory. It involves an understanding, for instance, of information diffusion processes in the different farming communities and territories, which provides a set of tools to promote and facilitate the adoption process in the context of adaptation to climate change and variability.
