abstract = {Crop diversification has many benefits both at the cropping system and the food system levels and has been addressed in agricultural research (Hufnagel et al., 2020). Landscape design and management in agricultural regions can support crop diversification by building bridges with scientific domains like ecology and geography (Benoit et al., 2012). Though, little is known on how the research community has addressed the crop diversification within a landscape perspective. In this paper we investigated a bibliographic corpus retrieved from the Scopus database papers coupling crop diversification and landscape (in title, abstract and keywords), retrieving 461 papers for the period 1990 to 2020. The corpus was analysed using the CorText platform (e.g., Ruiz-Martinez et al., 2015). First, natural language processing was used to extract multi-terms from title, abstract and keywords. Then, we mined the temporal dynamics and co-occurrence of the 100 most frequent terms. Our findings showed that species richness emerges as the main topic in this corpus, and that natural enemies, crop types and natural control increased in importance. In the last years, genetic diversity, climate change and agricultural production also gained attention. On the contrary, land use and some of the terms related to diversity (landscape, plant and farmland) were marginal or decreasing. By analysing the terms co-occurrence on the three decades, we observed that the papers addressing crop varieties and agroforestry system split into two streams: one about agricultural production in relation to climate change and the other about farm size and land use. Instead, the functional diversity and field margin disappeared from the recent literature. Land use patterns and landscape diversity converged mainly on studies about biological pest control. Altogether, the corpus highlighted that the spatial configuration lost in importance when addressing crop diversification. In addition, the species diversity gained in attention finally catching a large part of the literature in the corpus. From a landscape approach perspective, we might point out the apparent lack of a major topic: the involvement of local community and stakeholders. Our simple and rapid text mining approach yielded early evidence of knowledge gaps about the landscape level in crop diversification literature. The expected contribution of approaching the crop diversification at the landscape level would be to provide a relevant framework for the characterisation of the baseline system to be diversified. In particular, the landscape agronomy perspective stressed the need to define the scale and target area for crop diversification consistently with (natural and cultivated) species diversity embedded in a local socio-technical system.

abstract = {Landscapes are formed by the interactions between natural resources and heterogeneous land managers that expect/pursue an increasing variety of ecosystem services. Landscape ecology undoubtedly indicated the landscape as the best level to assess existing services and to support expected improvements. Where agriculture drives local dynamics, a contextual cross-scale analysis of farming activities and actors is needed to understand how and why landscapes are produced, eventually, redesigned. Inspired by landscape ecology, the landscape agronomy framework was proposed to extend the study of patterns and processes to agriculture, calling to focus on the spatially explicit characterization of farmers' decision-making. In summary, the landscape agronomy conceptual framework helps to describe and analyze the patterns determined by the interactions between agricultural practices and local resources (Benoit, Rizzo et al. 2012, Lands Ecol). This communication aims at providing insights into the key concepts underpinning the conceptual framework, such as the "cropping system" defined by agronomists, and the "force fields" applied in geography. A few years after the launch of this conceptual framework, we address the question: "who cares about landscape and agriculture?". To this aim, we will present the result of a bibliometric analysis using the CorText platform to explore research keywords, (inter)disciplinary bridges and emerging issues related to landscape agronomy. In the discussion, we will address some relevant applications, such as the challenges for agrifood system management of natural resources or to energy production by farmers (e.g., biofuel, biogas), and the landscape perspective on the deployment of smart farming and agtech. We will conclude on possible improvements to this conceptual framework. Altogether, this communication sets the scene for an upcoming multidisciplinary book about advances and challenges of a territorial approach to agricultural issues. },
