Although the benefits of genetically modified (GM) crops have been well documented, how do farmers manage the risk of new technology in the early stages of technology adoption has received less attention. We compare the total factor productivity (TFP) of cotton to other major crops (wheat, rice, and corn) in China between 1990 and 2015, showing that the TFP growth of cotton production is significantly different from all other crops. In particular, the TFP of cotton production increased rapidly in the early 1990s then declined slightly around 2000 and rose again.
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.
The aim of this survey is to identify and characterize new products in plant biotechnology since 2015, especially in relation to the advent of New Breeding Techniques (NBTs) such as gene editing based on the CRISPR-Cas system. Transgenic (gene transfer or gene silencing) and gene edited traits which are approved or marketed in at least one country, or which have a non-regulated status in the USA, are collected, as well as related patents worldwide. In addition, to shed light on potential innovation for Africa, field trials on the continent are examined.
Rwanda has experienced exceptional economic growth since 2000 despite more than 60% of the predominately-agrarian population living on less than $1.25 a day. Approximately 76% of the country’s working population are engaged in agricultural production, which makes up about one-third of the national economy. Agriculture is also an important source of foreign exchange, making up about 63% of the value of Rwanda’s exports.
Inclusive business models dominate current development policy and practices aimed at addressing food and nutrition insecurity among smallholder farmers. Through inclusive agribusiness, smallholder food security is presumed to come from increased farm productivity (food availability) and income (food access). Based on recent research, the focus of impact assessments of inclusive business models has been limited to instrumental aspects, such as the number of farmers supported, the training provided, and immediate farm outcomes, namely revenue.
Agricultural production systems are a composite of philosophy, adoptability, and careful analysis of risks and rewards. The two dominant typologies include conventional and organics, while biotechnology (GM) and Integrated Pest Management (IPM) represent situational modifiers. We conducted a systematic review to weigh the economic merits—as well as intangibles through an economic lens—of each standalone system and system plus modifier, where applicable. Overall, 17,485 articles were found between ScienceDirect and Google Scholar, with 213 initially screened based on putative relevance.
La crise économique et sanitaire due à la Covid-19 interpelle les trajectoires de reconfiguration des systèmes alimentaires en République du Congo. Elle questionne la capacité des mesures de régulation prises par les pouvoirs publics et des stratégies d’adaptation des acteurs à induire des inflexions dans la gouvernance structurelle du système alimentaire du pays. L’article analyse les stratégies d’adaptation à la crise en mobilisant des données secondaires et des expériences d’accompagnement de politiques publiques agricoles et alimentaires conduites par les auteurs.
While vaccination campaigns against COVID-19 were launched worldwide, a drama has been unfolding in the Moroccan countryside. It has been marked, over the last couple of decades, by rapid agrarian transformation, manifestations of which have included expanding irrigation frontiers and the increasing growth of high-value crops. These dynamics rely strongly on female agricultural wageworkers. Although they earn low wages, their income is crucial and is used to care for loved ones by paying for school fees, rent, electricity, and medicines.
Le secteur agricole constitue une activité importante au Maroc, représentant 14 % du produit national brut et employant 40 % de la population active. Avec l’émergence de la pandémie de la Covid-19, il a été ébranlé par des incertitudes économiques et par la distanciation physique qui a accentué les contraintes du travail. Toutefois, l’agriculture s’est imposée comme une activité cruciale, puisqu’elle a continué à assurer l’approvisionnement alimentaire à des prix abordables.
Cet article présente une évaluation théorique de la performance urbaine des modèles alimentaires alternatifs dans la prise en charge des objectifs de développement durable (ODD) en vue d’améliorer la sécurité alimentaire urbaine. Elle concerne les modèles des systèmes alimentaires les plus relatés dans la littérature, à savoir le système alimentaire territorialisé (SAT), le City-Region Food System (CRFS) et le système alimentaire urbain intelligent (SAUI) en émergence.
