Les populations africaines font partie des plus vulnérables face au changement climatique, du fait de leurs situations géographiques et économiques. Dans certaines régions du continent, où la variabilité climatique actuelle limite déjà la production agricole, le changement climatique pourrait l’inhiber complètement en l’absence de mesures pour adapter les systèmes agraires existants aux nouveaux contextes. Les paysans, qui représentent 70 à 80 % des agriculteurs en Afrique, seront très certainement les plus vulnérables face au changement climatique.
Impératif de développement et impératif de lutte contre le changement climatique sont plus que jamais liés. Le changement climatique accentue les inégalités en touchant de plein fouet les populations les plus pauvres. En accentuant la vulnérabilité de ces pays, il compromet chaque jour un peu plus leurs chances de se développer. C’est pourquoi, depuis 2007, Coordination SUD1 et le RAC-France ont décidé d’unir leurs forces pour peser davantage sur la position de la France dans le cadre des négociations internationales sur le climat.
Global adoption of transgenic crops reached 67.7 million hectares in 2003 from 2.8 million in 1996. Delivery has occurred almost entirely through the private sector and adoption has been rapid in areas where the crops addressed serious production constraints and where farmers had access to the new technologies. Three countries (USA, Argentina and Canada), three crops (soybean, cotton and maize) and two traits (insect resistance and herbicide tolerance) account for the vast majority of global transgenic area.
Grown in Jamaica since the days of slavery, food yams are major staples in local diets and a significant non-traditional export crop. The cultivation system used today is the same as 300 years ago, with alleged unsustainable practices. A new cultivation system called minisett was introduced in 1985 but the adoption rate twenty four years later is extremely low.
Given the search for new solutions to better prepare cities for the future, in recent years, urban agriculture (UA) has gained in relevance. Within the context of UA, innovative organizational and technical approaches are generated and tested. They can be understood as novelties that begin a potential innovation process. This empirical study is based on 17 qualitative interviews in the U.S. (NYC; Philadelphia, PA, USA; Chicago, IL, USA).
The objective of the study was to outline the determinants of market awareness and participation in the Kaonafatso ya Dikgomo (KyD) scheme in South Africa. The study utilised a cross-sectional survey of a randomly selected sample of 116 KyD farmers in KwaZulu-Natal Province. A Logit model was used to analyse the data. The results show that more farmers are aware of farmgate market channels, but however, they tended to utilise auction market channels.
The agrarian system Analysis and Diagnosis is used for this study, the goal of which was to provide a corpus of basic knowledge and elements of reflection necessary for the understanding the Niayes farming systems dynamics in Senegal, West Africa. Such holistic work has never been done before for this small region that provides the majority of vegetables in the area, thanks to its microclimate and access to fresh water in an arid country.
To meet global demands towards food security, safety as well as sustainable agriculture and food systems innovative approaches are inevitable. Despite the growing body of literature in both innovation research and in values and aims, what has been explored to a lesser extent is the bridging link between these areas. This study represents a first step in addressing this relationship.
Iran faces environmental challenges such as erosion and extreme events, namely droughts and floods. These phenomena have frequently affected the country over the past decades and temperature rise has led to a more challenging situation. Iran started to implement national and provincial policies in the 1950s to cope with these phenomena. To provide an overview of Iran’s efforts to tackle land degradation and climate change, this paper examined through literature since 2000 the stakeholders’ policies, their interventions and obstacles to the mitigation of these environmental challenges.
Agricultural knowledge and innovation system (AKIS) has a strong potential to enhance economic performance of farming and contribute to agricultural sustainability, as it may increase synergies and complementarity among actors. This paper is aimed to develop a proposed framework to strengthen AKIS in the study area based on the results of this study. This paper explores perception and views about strengthening AKIS in Dakhalia governorate of Egypt by applying a multi-actor approach. Quantitative and qualitative data were collected through face-to-face interviews and focus group discussion.
