“…Thus, NPP is the difference between photosynthesis and autotrophic respiration (Field et al 1998). In this context, NPP of ecosystems is a highly relevant metric for assessing 'limits to growth' (Erb et al 2009;Marull et al 2015;Running 2012) and a key determinant of agronomic yield.…”

In agroforestry systems, shade trees strongly affect the physiology of the undergrown crop. However, a major paradigm is that the reduction in absorbed photosynthetically active radiation is, to a certain extent, compensated by an increase in light-use efficiency, thereby reducing the difference in net primary productivity between shaded and non-shaded plants. Due to the large spatial heterogeneity in agroforestry systems and the lack of appropriate tools, the combined effects of such variables have seldom been analysed, even though they may help understand physiological processes underlying yield dynamics. In this study, we monitored net primary productivity, during two years, on scales ranging from individual coffee plants to the entire plot. Absorbed radiation was mapped with a 3D model (MAESPA). Light-use efficiency and net assimilation rate were derived for each coffee plant individually. We found that although irradiance was reduced by 60% below crowns of shade trees, coffee light-use efficiency increased by 50%, leaving net primary productivity fairly stable across all shade levels. Variability of aboveground net primary productivity of coffee plants was caused primarily by the age of the plants and by intraspecific competition among them (drivers usually overlooked in the agroforestry literature) rather than by the presence of shade trees.

“…Our research is part of an energy-landscape integrated approach (ELIA) [10,41], in which we explicit biomass and energy flows across different land uses (MuSIASEM). The combination of ELIA and MuSIASEM provides solid foundations for a better understanding of landscape agroecology that can inform policies for the design of agro-ecological landscapes.…”

The paper analyses how between 1956 and 2009 the agrarian metabolism of the Barcelona Metropolitan Region (BMR) has become less functional, losing circularity in biomass flows and in relationship to its landscape. We do so by adopting a Multi-Energy Return on Investment (EROI) and flow-fund (MuSIASEM) analyses and the nexus with landscape functional structure. The study of agricultural flows of Final Produce, Biomass Reused and External Inputs is integrated with that of land use, livestock, power capacity, and population changes between 1956 (at the beginning of agrarian industrialization) and 2009 (fully industrialized agriculture). A multi-scale analysis is conducted at the landscape scale (seven counties within the Barcelona metropolitan region) as well as for the functions deployed, within an agroecosystem, by the mutual interactions between its funds (landscape, land-uses, livestock, and farming population). A complex nexus between land, livestock, dietary patterns, and energy needs is shown; we conclude that, from the perspective of the circular bioeconomy the agrarian sector has gone worse hand in hand with the landscape functional structure. Therefore, a novel perspective in landscape agroecology is opened.

“…That is why internal agroecosystem biomass recirculation can explain a lot. Tello et al's approach (2016) linked to landscape analysis [41,42] is paving the way for a new perspective in landscape agroecology. Here, the double flow of internal biomass recirculation between the land and the livestock sub-systems needs balancing, not only in the dimension of the incoming and outgoing flows, but also in the diversity of land uses and animal typologies that are involved, so that dependence on External Inputs is minimized and the agroecosystem is not dysfunctional and resembles more a sustainable organism [33].…”

“…The current state of research in landscape agroecology is set in the outcomes of the Sustainable Farm Systems research project, which has focused on an innovative development of EROI analysis [29,41,69,71] also merging it with MuSIASEM [74], on nutrient cycles [72,73] and on the original development of Energy-Landscape Integrated Analysis [40][41][42][43], which in turn draw from previous work on social metabolism [20,75,77] and EROI analysis [76]. As well, these novel methods applied in landscape agroecology can bridge with and contribute to the land sharing/sparing debate [78] which is still a controversial issue [79,80] The main aim of this paper is to assess, for the case study of the Barcelona Metropolitan Region, the loss in sustainability that has occurred as a result of agricultural industrialization by highlighting the virtues of a past model that could inspire future developments towards more sustainable agriculture, landscape and diets.…”
