The research and development needed to achieve sustainability of African smallholder agricultural and natural systems has led to a wide array of theoretical frameworks for conceptualising socioecological processes and functions. However, there are few analytical tools for spatio-temporal empirical approaches to implement use cases, which is a prere...

It has increasingly been recognized that developing successful obesity prevention policies and interventions requires understanding of the complex mechanisms driving the obesity pandemic and that models could be useful tools for simulating policies. This paper reviews system dynamics simulation models of mechanisms driving childhood overweight and ...

Objectives: Health economic evaluations (HEEs) help healthcare decision makers understand the value of new technologies. Artificial intelligence (AI) is increasingly being used in healthcare interventions. We sought to review the conduct and reporting of published HEEs for AI-based health interventions. Methods: We conducted a systematic literature...
Across the globe, river flows are being altered by human activity, such as water extraction and diversion, and the construction of dams. At the same time precipitation is becoming more erratic as climate change accelerates, leading to shifting rainy seasons, prolonged drought, and intense flooding.
From its sources in the western mountains and plateau of Mpumalanga in South Africa to its mouth just north of Maputo’s bustling docks in Mozambique, the Incomati River basin supports lives, livelihoods, and irreplaceable ecosystems across eastern Southern Africa. However, growing irrigation and energy needs and accelerating climate change have pla...
This webinar discusses application of a nexus tool to support water allocation reform in the Incomati Basin. NEXUS Gains has partnered with INMACOM and the University of Manchester to build a robust and comprehensive river basin systems model using an open-source Python water resources (Pywr) framework that accounts for water demands from agricultu...

The famous singlet correlations of a composite quantum system consisting of two two-level components in the singlet state exhibit notable features of two kinds. One kind are striking certainty relations : perfect anti-correlation, and perfect correlation, under certain joint settings. The other kind are a number of symmetries , namely invariance un...

Our ability to predict natural phenomena can be limited by incomplete information. This issue is exemplified by "Laplace's demon," an imaginary creature proposed in the 18th century, who knew everything about everything, and thus could predict the full nature of the universe forward or backward in time. Quantum mechanics, among other things, has ca...
Las Comunicaciones Nacionales sobre Cambio Climático (CNCC) son un mecanismo para que los países informen sus avances en mitigación y adaptación, y constituyen uno de los elementos de base para la política sobre cambio climático a escala nacional. Colombia ha emitido tres CNCC. La tercera plantea un escenario que considera las proyecciones de diver...
Structural change is integral to evolving economies (Goddard et al., 1993). Although increased agricultural productivity has allowed the release of resources needed by other sectors of the economy, structural change in agriculture usually has a negative connotation in public debate (Balmann and Valentinov, 2016). There are mainly two types of publi...
