Abstract:
... Crop simulation models play an increasingly important role in agricultural management. Therefore, improving crop models’ accuracy and reliability has become a key issue. Previous studies have shown that multi-model ensembles (MMEs) perform better than individual models and are capable of assessing model uncertainty. Here, we study the use of the Bayesian model averaging (BMA) method to improve the ...

Abstract:
... The use of synthetic fungicides to control fungal diseases has growing limitations due to eco-toxicological risks. Therefore, it is necessary to replace or integrate high risk chemicals with safer tools for human health and environment. Consequently, research on the selection, evaluation, characterization, and use of biocontrol agents (BCAs) has consistently increased in the last decades. BCA form ...

Abstract:
... Recent advances in molecular ecology have dramatically improved our knowledge of soil microbial diversity and offers new indicators of soil quality. The usefulness of diversity indices has never been greater as the astronomical amounts of data generated in the literature needs to be synthesized. Despite technical guidelines have been proposed to characterize soil microbiomes using high throughput ...

Abstract:
... Despite the potential of diversification strategies to achieve sustainability, diversified systems such as agroforestry are still not widely implemented by farmers, which indicates the need to further understand and adequately assess the impacts of diversification to inform the design of complex systems. In this paper, we conduct a systematic literature review focused on agroforestry coffee system ...

Abstract:
... The reliability of crop-growth modelling is related to the accuracy of the information used to describe the agricultural growing phases. A proper knowledge of sowing periods has a significant impact on the effectiveness of any analysis based on modeled crop growth. In this work, an estimation of maize actual sowing periods for year 2019 is presented, combining the optical and radar information fro ...

Abstract:
... Using a panel of nearly 3000 agricultural households in Tanzania and Mozambique from 2016–2018, this paper investigates the associations of nutritional outcomes and agricultural management practices under drought risk. We show drought has significant consequences on two nutritional outcomes in particular: food security and dietary diversity. Importantly, these consequences are evident even for hou ...

Abstract:
... Ecosystem services can be defined as the ecosystem’s contribution to human activities. According to recent assessments, the agricultural sector is one of the most important economic users of ecosystem services in Europe. To assess, value, and account for ecosystem services related to the agri-food system offers the possibility to measure and investigate how agricultural management practices togeth ...

Abstract:
... Changes in land policy not only determine agricultural growth, but also have bearing on issues, such as peasants’ rights and interests, industrial development, and urbanization. On account of China’s singular history and culture, its land systems are somewhat unique. This paper analyzes the institutional changes that took place before and after 1978 to show the journey of land system reform in rur ...

Abstract:
... Non-grain production has emerged as a potential threat to grain production capacity and security in China. Agricultural products with higher economic returns are beginning to replace traditional grain crops, which have relatively low economic returns on a large scale. In this study, we proposed and verified an identification method utilizing an unmanned aerial vehicle and a U-net algorithm to dist ...

Abstract:
... Conversions of soil pH values between different methods are required for the standardization of data from international scientific literature, soil test reports and soil databases. All commonly employed matrices (H₂O, 0.01 M CaCl₂ and 1 M KCl) and relevant soil:solution ratios (1:1, 1:2.5, 1:4 and 1:5) used for pH measurement have yet to be compared using the same sample dataset. The combined effe ...

Abstract:
... Cropland plays an important role in Soil Organic Carbon (SOC) sequestration. Although the SOC stock and its dynamic in the past decades have been extensively investigated, the information as to where, how much, and how SOC could be potentially sequestered in the coming decades has rarely been available. Here, the Rothamsted Carbon model was applied to investigate the spatiotemporal pattern of SOC ...

Abstract:
... This article outlines the importance of place-based policies derived from knowledge on local realities. Through an analysis of maize policies and their impact on the Zambezi region, Namibia, we illustrate the constraining limitations of insufficiently place-based policies. We highlight the problems of current top-down policies of production promotion, value chain integration, and sector protection ...

Abstract:
... Concerns about the effects of global warming on crop yields have risen due to stagnating yield progress in recent years. Understanding crop traits and grain yield variations in different climate zones is critical to gain insights into crop response and adaptation mechanisms to ongoing climate change. However, the interactions of genotype, environment and management on crop traits and historical yi ...

Abstract:
... Leaching of nitrogen from arable land can lead to pollution of groundwater and surface water. Various measures have been implemented in agriculture to reduce leaching, but there is still potential to do more. To find the best agricultural management regime to limit the problem, leaching from soils under different management must be measured. Different methods to estimate leaching are available, bu ...
