This paper looks at brokerage functions in a project on building innovation capacity through improved networking. Innovation capacity influences how actors respond to changes in their environments. In such dynamic environments well connected sets of actors are at an advantage in that they can combine skills to address the emerging opportunities and challenges. However, policy and cultural barriers especially in African innovation systems raise the transaction costs of networking leading to weak connectivity among actors thus poor innovation capacity.
Understanding spatial patterns of land use and land cover is essential for studies addressing biodiversity, climate change and environmental modeling as well as for the design and monitoring of land use policies. The aim of this study was to create a detailed map of land use land cover of the deforested areas of the Brazilian Legal Amazon up to 2008.
The increasing demand for agricultural commodities is a major cause of tropical deforestation. However, pressure is increasing for greater sustainability of commodity value chains. This includes the demand to establish new crop plantations and pasture areas on already deforested land so that new forest clearing for agriculture is minimized. Where tree crops are planted as part of agroforestry systems on deforested land, this amounts to a form of re-agro-forestation which can generate environmental benefits in addition to crop production.
Providing food and other products to a growing human population while safeguarding natural ecosystems and the provision of their services is a significant scientific, social and political challenge. With food demand likely to double over the next four decades, anthropization is already driving climate change and is the principal force behind species extinction, among other environmental impacts. The sustainable intensification of production on current agricultural lands has been suggested as a key solution to the competition for land between agriculture and natural ecosystems.
Transgenic maize was approved in Brazil in 2008/2009. In 2012, it occupied 73% of the country maize growing area. This high adoption rate confirms studies indicating that technology use has been the major driving force in Brazilian agriculture. Maize seed market in the world has been a concentrated sector. Although, when this sector is associated with transgenesis, this concentration increases sharply. In one side, there is the idea that companies can benefit from gains of scale and complementarities to maximize their efficiency in research and development (R&D).
Findings from a survey on sources of income and land allocation outcomes of 578 households from 26 communities with diverse ethnic composition at distinct environmental settings in Ucayali (Peruvian Amazon) are used to contrast livelihood strategies featuring high forest and high agriculture dependency, examining whether agricultural intensification can be linked to lower deforestation. A typology of households based on their land use allocation profile was used to assess current and cumulative cleared land.
L'article propose d'utiliser le concept de sécurisation alimentaire pour étudier les actions et processus qui améliorent une situation alimentaire, plutôt que celui de sécurité alimentaire qui se réfère avant tout à la satisfaction de besoins alimentaires. Dans une première partie, ces deux concepts sont précisés et discutés. La sécurité alimentaire est caractérisée selon plusieurs dimensions : disponibilités, conditions d'accès, qualités des aliments, stabilité, mais aussi objectifs sociaux et politiques.
La Tunisie cherche à réorienter ses politiques d'Aménagement et de conservation des eaux et des sols (ACES) afin qu'elles gagnent en efficacité, en s'appuyant sur des démarches participatives innovantes. Cette orientation s'inscrit dans des contextes ruraux souvent peu documentés où la dimension environnementale nécessite d'être objectivée. De plus, il existe peu d'espaces de dialogue et de concertation entre les principales catégories d'acteurs des espaces ruraux concernés.
La présente note commence par indiquer brièvement en quoi une politique de la concurrence est importante pour les économies en développement et en transition. Elle aborde ensuite certains éléments essentiels de l’établissement d’une culture de la concurrence. Idéalement, ce processus devrait tout d’abord consister en une « évaluation des besoins » dans différents domaines, qui permettra probablement de dresser une liste de mesures à hiérarchiser et à prendre.
Ce document examine les approches suivies actuellement en ce qui concerne le renforcement des capacités commerciales dans les pays africains. Ce but est de:
Identifier des mécanismes permettant de promouvoir un processus de formulation de la politique commerciale de type participatif et de l’intégrer dans les stratégies nationales de développement et de lutte contre la pauvret.
Etudier le rôle que pourraient jouer les donneurs en facilitant et en soutenant le processus d’élaboration de la politique commerciale.
