Abstract:
... Precision viticulture (PV) is a relatively new discipline, whose development started in the 1990s. PV aims at adjusting vineyard management to the spatial variability that naturally appears in the field in order to increase its economic and environmental sustainability. Despite the rapid growth of PV in the last two decades, there is little PV research taking advantage of the great potential advan ...

Abstract:
... Agricultural wood (the cultivation of fast growing short rotation trees) is a way of complying with the Greening restrictions of the current European Common Agricultural Policy (CAP). The CAP permits Short Rotation Coppice (SRC) and Alley Cropping Systems (ACS) as Ecological Focus Area (EFA) methods of agricultural wood cultivation, although the latter method – which is a kind of Agroforestry Syst ...

Abstract:
... This article extends social science research on big data and data platforms through a focus on agriculture, which has received relatively less attention than other sectors like health. In this paper, I use a responsible innovation framework to move attention to the social and ethical dimensions of big data “upstream,” to decision-making in the very selection of agricultural data and the building o ...

Abstract:
... The area cultivated with pollinator-dependent crops is increasing worldwide, while a shortfall in pollinator availability is a growing problem in many agroecosystems. For this reason, many highly pollinator-dependent crops are nowadays pollinated artificially by humans. Here, we compared the efficiency of artificial and bee pollination practices on the mean level and stability of pollination and f ...

Abstract:
... Global production network (GPN) analysts argue that workers actively contribute to the shaping of GPNs through different forms of agency. In this contribution I extend this argument to the tactical agency of small producers. By focusing on the phenomenon of side-selling among Filipino banana contract farmers, I show that these tactics have contributed to the emergence of alternative trade networks ...

Abstract:
... Catharanthus roseus is known for its anticancer bisindole alkaloids, vinblastine and vincristine that are derived from the condensation of monomeric terpenoid indole alkaloids (TIAs), catharanthine and vindoline. The in planta content of TIAs varies with seasons and ontogeny making it difficult for growers to define the optimal parameters for harvesting for specific TIAs. Here, specific leaf TIAs ...
