The transformative value chain: rethinking food system interventions

Value chain interventions and NCDs

insight into the impact of agriculture on the advance of non-communicable diseases (NCDs) in lowand middleincome countries (LMICs). The linked demographic and dietary transitions, away from rural areas and traditional foods and towards urban centres and more processed and energy-dense foods, are seen to precipitate rises in NCDs such as diabetes and cardiovascular disease. But the complex polit...

Permanency and Asymptotic Behavior of The Generalized Lotka-Volterra Food Chain System

In the present paper a generalized Lotka-Volterra food chain system has been studied and also its dynamic behavior such as locally asymptotic stability has been analyzed in case of existing interspecies competition. Furthermore, it has been shown that the said system is permanent (in the sense of boundedness and uniformly persistent). Finally, it is proved that the nontrivial equilibrium point...

Rethinking the value of high wood density

1. Current thinking holds that wood density mediates a tradeoff between strength and economy of construction, with higher wood density providing higher strength but at higher cost. 2. Yet the further away wood fibres are from the central axis of the trunk, the more they increase the strength of the trunk; thus, a fat trunk of low-density wood can achieve greater strength at lower construction c...
