  1. Adaptive scaling ecosystem for system transformation: operationalizing solar-based farmer-led irrigation in Sub-Saharan Africa by Minh, Thai Thi, Schmitter, Petra

    Published 2025
    “…ASEco enables multiple pathways that combine niche development, market reach, the acceleration of enabling environments, and transformative shifts in rules and norms. It translates food-system complexity into actionable levers by clarifying ecosystem boundaries, aligning actor networks with scaling functions, and fostering continuous adaptation through feedback and coevolution, thereby managing non-linear dynamics and trade-offs. …”

  2. High methane uptake from soils of low and high density radiata pine afforestations compared to herbaceous systems by De Bernardi, María, Priano, María Eugenia, Fusé, Victoria, Fernandez, María Elena, Gyenge, Javier, Guzmán, Sergio, Julianera, María

    Published 2020
    “…The statistical differences of these parameters could partially justify CH4 flux differences found among treatments. However, a multiple linear regression analysis indicated that other factors such as soil temperature also control CH4 fluxes (R2 = 0.86, p≪4x10−6), and could explain temporal patterns. …”

  3. The effects of nitrogen fertilizer rates in a long-term reduced tillage cropping system on dry matter and nitrogen accumulation in an oil radish (Raphanus sativus L.) cover crop by Chawdhery, Md. Rafique Ahasan

    Published 2012
    “…According to the hypothesis, the observations of DM production and N accumulation were expected to be in a linear trend with the N levels but they were highly significant with the N levels without any linear increasing tendency. …”

  4. Performance and physical body measurement of Abergell sheep breed in traditional management system of Tigray Regional State, northern Ethiopia by Tajebe, S., Gangwar, S.K., Kebede, K.

    Published 2011
    “…Prior to analysis the sampled sheep are classified in to three groups based on availability of permanent incisors as one, two, and three pair of permanent teeth. Simple and multiple linear regression analyses were applied to develop and predict equations for body weight of animals using each of the linear body measurements separately or in combination. …”

  5. Direct Nitrous Oxide Emissions From Tropical And Sub-Tropical Agricultural Systems - A Review And Modelling Of Emission Factors by Albanito, Fabrizio, Lebender, Ulrike, Cornulier, Thomas, Sapkota, Tek Bahadur, Brentrup, Frank, Stirling, Clare M., Hillier, Jon

    Published 2017
    “…In this study, we report an up-to-date review of the information published in peer-review journals on direct N2O emissions from agricultural systems in tropical and sub-tropical regions. We statistically analyze net-N2O-N emissions to estimate tropic-specific annual N2O emission factors (N2O-EFs) using a Generalized Additive Mixed Model (GAMM) which allowed the effects of multiple covariates to be modelled as linear or smooth non-linear continuous functions. …”

  6. Complementarity of value chain analysis, consumption patterns and nutrition in the design of sustainable, effective and efficient food-system-based interventions by Domínguez Salas, Paula, Hasler, B., Ferguson, E., Cornelsen, L., Alonso, Silvia, Fèvre, Eric M., Rushton, Jonathan, Grace, Delia, Alarcón, Pablo

    Published 2015
    “…Methods: We conducted two parallel investigations in Nairobi: a cross-sectional nutrition survey in consumers of 205 randomly selected low-income households, in Korogocho and deprived areas of West Dagoretti; and a large-scale characterisation and analysis of the different animal-source food systems of the city. Retailers were the linkage node between consumers and food systems data. …”

  8. Effect of potato (Solanum tuberosum L.) cropping systems on soil and nutrient losses through runoff in a humic nitisol by Nyawade, S.

    Published 2015
    “…Statistically significant linear dependence of runoff and soil loss on surface roughness and crop cover was found in T4 (p<0.05) indicating that this system was highly effective in minimizing soil loss and runoff. …”
