Aligning Global Efforts for a Carbon Neutral World: The Race to Zero Campaign

2022 , SEVIL ESTEBAN, ANGEL , Gonzalo Muñoz , GODOY FAUNDEZ, ALEX ORIEL

According to the United Nations, in order to avoid some of the worst outcomes of climate change, the world must achieve net zero carbon emissions by 2050 at the very latest. That is the aim of the Race to Zero Campaign. Since 2019, more than 10,000 organizations around the world have embraced Race to Zero, which has been able to successfully create a relevant, global, and diverse cross-sector partnership, tearing down the barriers that have emerged from uncertainty. Building on three key cross-partnership elements (strategic, institutional, and learning), combined with the uncertainties faced by the partners, we describe the resources and activities that have made that possible.

Estimation of Yield Response Factor for Each Growth Stage under Local Conditions Using AquaCrop-OS

2020 , Mathias Kuschel-Otárola , Niels Schütze , Eduardo Holzapfel , GODOY FAUNDEZ, ALEX ORIEL , Oleksandr Mialyk , RIVERA SALAZAR, DIEGO ANDRÉS

We propose a methodology to estimate the yield response factor (i.e., the slope of the water-yield function) under local conditions for a given crop, weather, sowing date, and management at each growth stage using AquaCrop-OS. The methodology was applied to three crops (maize, sugar beet, and wheat) and four soil types (clay loam, loam, silty clay loam, and silty loam), considering three levels of bulk density: low, medium, and high. Yields are estimated for different weather and management scenarios using a problem-specific algorithm for optimal irrigation scheduling with limited water supply (GET-OPTIS). Our results show a good agreement between benchmarking (mathematical approach) and benchmark (estimated by AquaCrop-OS) using the Normalised Root Mean Square Error (NRMSE), allowing us to estimate reliable yield response factors ( K y ) under local conditions and to dispose of the typical simple mathematical approach, which estimates the yield reduction as a result of water scarcity at each growth stage.

Exploring the Roles of Local Mobility Patterns, Socioeconomic Conditions, and Lockdown Policies in Shaping the Patterns of COVID-19 Spread

2021 , HERRERA MARÍN, MAURICIO RENÉ , GODOY FAUNDEZ, ALEX ORIEL

The COVID-19 crisis has shown that we can only prevent the risk of mass contagion through timely, large-scale, coordinated, and decisive actions. This pandemic has also highlighted the critical importance of generating rigorous evidence for decision-making, and actionable insights from data, considering further the intricate web of causes and drivers behind observed patterns of contagion diffusion. Using mobility, socioeconomic, and epidemiological data recorded throughout the pandemic development in the Santiago Metropolitan Region, we seek to understand the observed patterns of contagion. We characterize human mobility patterns during the pandemic through different mobility indices and correlate such patterns with the observed contagion diffusion, providing data-driven models for insights, analysis, and inferences. Through these models, we examine some effects of the late application of mobility restrictions in high-income urban regions that were affected by high contagion rates at the beginning of the pandemic. Using augmented synthesis control methods, we study the consequences of the early lifting of mobility restrictions in low-income sectors connected by public transport to high-risk and high-income communes. The Santiago Metropolitan Region is one of the largest Latin American metropolises with features that are common to large cities. Therefore, it can be used as a relevant case study to unravel complex patterns of the spread of COVID-19.
