Demand for crop genetic resources and the US National Plant Germplasm System by Day-Rubenstein, Kelly, Smale, Melinda, Widrlechner, Mark P.

“…To explore relationships between the usefulness of germplasm samples and accompanying data in a more systematic fashion, we estimated a linear regression. The regression model suggests that accompanying data make germplasm more useful. …”

Innovation systems perspectives on developing-country agriculture: A critical review by Spielman, David J.

“…The more theoretical innovation systems literature represents a significant change from the conventional, linear perspectives on agricultural research and development (R&D) by providing a framework for the analysis of complex relationships and innovative processes that occur among multiple agents, social and economic institutions, and endogenously determined technological and institutional opportunities. …”

Smallholders’ avocado production systems and tree productivity in the southern highlands of Ethiopia by Biazin, B., Haileslassie, Amare, Zewdie, T., Mekasha, Yoseph, Gebremedhin, Berhanu, Fekadu, A., Shewage, Tesfaye

“…Productivity of avocado was significantly (p < 0.05) different between production systems. The highest avocado fruit yield was observed from trees grown in the coffee and enset-based agroforestry systems. …”

Characterization of the low affinity transport system for NO3- uptake by Citrus roots by Cerezo, Miguel, Flors, Victor, Legaz, Francisco, Garcia-Agustin, P.

“…Two different NO; uptake systems were found. Between 1 and 50 mM (NO3)-N-15 in the uptake solution medium, the uptake rate increased linearly due to the low affinity transport system (LATS). …”

Summary: creating systems innovation platforms for transformative pathways in circular economy by Sobratee‑Fajurally, Nafiisa, Nhamo, L., Mabhaudhi, Tafadzwanashe

“…These are organised as (i) realising that the current equilibrium is outdated and skewed towards linearity such that impacts are additive but non-systemic, (ii) creating a new culture for enabling transformative patterns by connecting actors who share a new set of values, (iii) enabling Community of Practice (CoP) that share a common identity, (iv) connecting resources in novel ways by repurposing existing capacities, that is, extending the ontology of the CE, (v) institutionalising and supporting new networked configurations till normalisation, and (vi) impacts become systemic through synergies, trade-offs and comprise are negotiated and new patterns co-exist and are visible. …”

Strategies for improving water use efficiency of livestock production in rain-fed systems by Ergano, Kebebe, Oosting, Simon J., Haileslassie, Amare, Duncan, Alan J., Boer, Imke J.M. de

“…The objective of this paper was to identify the factors that explain the variation in LWP within and among farming systems in Ethiopia. We quantified LWP for various farms in mixed-crop livestock systems and explored the effect of household demographic characteristics and farm assets on LWP using ANOVA and multilevel mixed-effect linear regression. …”

Technical Guide: Systems-based approach to understanding, steering and guiding change in Aquatic foods by Manyise, Timothy, Rossignoli, Cristiano, Dentoni, Domenico

“…This guide provides a practical framework for project managers and practitioners to understand and address the complexities of agrifood systems, including aquatic foods. Traditional approaches, like linear Theory of Change (TOC) models, often overlook the intricate relationships and non-linear dynamics within these systems, potentially leading to incomplete assessments of project impacts. …”
