Inscrites sur la liste du patrimoine mondial de l’Unesco pour leur témoignage des techniques préhispaniques d’agriculture sur l’eau, les chinampas de Xochimilco sont le dernier grand espace non urbanisé de la ville de Mexico. Le site est le support d’une multitude de fonctions dont la promiscuité engendre inévitablement des tensions entre les acteurs. Localisées au cœur de la capitale, les chinampas subissent également les effets de la pression urbaine qui tend à concurrencer spatialement les autres activités et à accentuer les dégradations environnementales.
L’agriculture française fait l’objet de critiques du fait des pressions qu’elle exerce sur les ressources naturelles, des transformations qu’elle opère sur les paysages et de la qualité parfois contestée de ses productions. Face aux attentes sociales et aux pressions réglementaires, des agriculteurs ont choisi de s’organiser en réseau pour proposer des pratiques agricoles alternatives. Une véritable dynamique est en œuvre chez ces agriculteurs minoritaires qui cherchent à diffuser leurs expériences en créant de nouveaux liens au sein de la population agricole.
L’Agriculture de Conservation est un système s’inscrivant dans la démarche de l’agroécologie, fondé sur le non-labour, la couverture permanente du sol par des végétaux et des rotations longues et diversifiées. Le système vise à améliorer la productivité sur le long terme en respectant les services écosystémiques générés par l’activité biologique du sol et la matière organique qu’il contient. Les techniques de non-labour se sont développées sur le continent américain et en Australie. Elles prennent à présent de l’ampleur en Europe.
Agricultural innovation in low-income tropical countries contributes to a more effective and sustainable use of natural resources and reduces hunger and poverty through economic development in rural areas. Yet, despite numerous recent public and private initiatives to develop capacities for agricultural innovation, such initiatives are often not well aligned with national efforts to revive existing Agricultural Innovation Systems (AIS).
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.
The agricultural industry is getting more data-centric and requires precise, more advanced data and technologies than before, despite being familiar with agricultural processes. The agriculture industry is being advanced by various information and advanced communication technologies, such as the Internet of Things (IoT). The rapid emergence of these advanced technologies has restructured almost all other industries, as well as advanced agriculture, which has shifted the industry from a statistical approach to a quantitative one.
Indicator-based tools are widely used for the assessment of farm sustainability, but analysts still face methodological and conceptual issues, including data availability, the complexity of the concept of sustainability and the heterogeneity of agricultural systems. This study contributes to this debate through the illustration of a procedure for farm sustainability assessment focussed on the case study of the South Milan Agricultural Park, Italy. The application is based on a set of environmental, social and economic indicators retrieved from the literature review.
The process of adopting innovation, especially with regard to precision farming (PF), is inherently complex and social, and influenced by producers, change agents, social norms and organizational pressure. An empirical analysis was conducted among Italian farmers to measure the drivers and clarify “bottlenecks” in the adoption of agricultural innovation. The purpose of this study was to analyze the socio-structural and complexity factors that affect the probability to adopt innovations and the determinants that drive an individual’s decisions.
In recent decades, the confluence of different global and domestic drivers has led to progressive and unpredictable changes in the functioning and structure of agri-food markets worldwide.
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.
