Fall Armyworm (Spodoptera frugiperda), or FAW, is an insect native to tropical and subtropical regions of the Americas. In the absence of natural controls or good management, it can cause significant damage to crops. It prefers maize, although it can feed on more than 80 additional species of crops including rice, sorghum, millet, sugarcane, vegetable crops and cotton.
Rice is one of the most important food crops in sub-Saharan Africa. Climate change, variability, and economic globalization threatens to disrupt rice value chains across the subcontinent, undermining their important role in economic development, food security, and poverty reduction. This paper maps existing research on the vulnerability of rice value chains, synthesizes the evidence and the risks posed by climate change and economic globalization, and discusses agriculture and rural development policies and their relevance for the vulnerability of rice value chains in sub-Saharan Africa.
Boundary-spanning search for knowledge is an effective way for enterprises to acquire heterogeneous knowledge, and is also an important pre-stage to realize effective knowledge reconstruction. Based on the boundary-spanning search for knowledge theory, this paper studies the relationship between boundary-spanning search for knowledge and the sustainable innovation ability of agricultural enterprises considering the influence of organizational knowledge reconstruction, from a Chinese perspective.
Conflicts of interests have been hypothesized when agricultural advisory services are connected to agri-input businesses. However, these have not been examined using large sets of advisory service and grower data. We provide quantitative insights into dependencies between service, crop production, sustainability and the level of agri-input business-linkage of extension workers. This study analyzed 34,000+ prescription forms (recommendations) issued to growers in China, as well as grower interview data.
There is a blossoming of voluntary certification initiatives for sustainable agro-food products and production processes. With these certification initiatives come traceability in supply chains, to guarantee the sustainability of the products consumed. No systematic analysis exists of traceability systems for sustainability in agro-food supply chains.
In recent years, the international status of agriculture in the BRICS countries—Brazil, Russia, India, China and South Africa—has been continuously improved. In 2018, the gross agricultural production of the BRICS countries accounted for more than 50% of the world’s total. Further strengthening the developing cooperation of the BRICS countries is of great significance for ensuring global food security.
The impact of global warming on crop growth periods and yields has been evaluated by using crop models, which need to provide various kinds of input datasets and estimate numerous parameters before simulation. Direct studies on the changes of climatic factors on the observed crop growth and yield could provide a more simple and intuitive way for assessing the impact of climate change on crop production.
This paper draws lessons from selected country experiences of adaptation and innovation in pursuit of food security goals.
Quels sont les effets de l’implantation de méga-exploitations agricoles sur les différents groupes d’intérêt des territoires locaux ? Cette implantation provoque-t-elle de fortes ruptures ou une simple accélération des dynamiques en cours ? Sur la base d’une étude de cas à Madagascar, cet article s’intéresse aux recompositions du système agraire à Madagascar engendrées par l’installation récente d’une entreprise privée étrangère. Tandis que l’emploi se développe au bénéfice des plus petits agriculteurs, l’accès à la terre évolue au détriment des éleveurs les plus aisés.
À Madagascar, au-delà de l'abandon fortement médiatisé du gigantesque projet agricole de l'entreprise Daewoo, les appropriations foncières à grande échelle se poursuivent. Mais, à la différence d'autres pays du Sud, une réforme foncière est en cours, fondée à la fois sur la remise en cause de la propriété de l'État sur une large part du territoire et la reconnaissance légale des droits fonciers locaux. Basé sur la théorie de l'accès, cet article analyse les modes d'accès à la terre des investisseurs et leurs régulations.
