A Super-Ensemble Approach To Map Land Cover Types With High Resolution Over Data-Sparse African Savanna Landscapes, Lei Song, Anna Bond Estes, Lyndon Despard Estes

Geography

Accurate and timely land cover products are critical inputs for landscape planning, and provide key information for biodiversity conservation and food security. However, poor mapping quality and low resolution are considerable issues in existing land cover maps over the African savanna, where land use is complex and changing rapidly, and necessary ground-truth data are sparse and hard to obtain. To overcome this problem, to make optimal use of existing maps, and to minimize manual training data collection, we developed a three-stage ensemble method to make land cover maps. In the first stage, we extracted the consensus of multiple existing land …

Narrating Agricultural Resilience After Hurricane María: How Smallholder Farmers In Puerto Rico Leverage Self-Sufficiency And Collaborative Agency In A Climate-Vulnerable Food System, Abrania Marrero, Andrea Lόpez-Cepero, Ramón Borges-Méndez, Josiemer Mattei

Sustainability and Social Justice

Climate change is a threat to food system stability, with small islands particularly vulnerable to extreme weather events. In Puerto Rico, a diminished agricultural sector and resulting food import dependence have been implicated in reduced diet quality, rural impoverishment, and periodic food insecurity during natural disasters. In contrast, smallholder farmers in Puerto Rico serve as cultural emblems of self-sufficient food production, providing fresh foods to local communities in an informal economy and leveraging traditional knowledge systems to manage varying ecological and climatic constraints. The current mixed methods study sought to document this expertise and employed a questionnaire and narrative interviewing …

Impact Pathways From Climate Services To Sdg2 (“Zero Hunger”): A Synthesis Of Evidence, James Hansen, Geneva List, Shauna Downs, Edward Carr, Rahel Diro, Walter Baethgen, Andrew Kruczkiewicz, Melody Braun, John Furlow, Kayla Walsh, Nitin Magima

Sustainability and Social Justice

Climate services can help address a range of climate-sensitive development challenges, including agricultural production and food security. However, generating empirical evidence of impact is challenging. In this paper, we synthesize published evidence of pathways by which climate services contribute to improved food security. A summary of key mechanisms by which climate risk drives food insecurity provides a context for understanding potential climate risk management interventions. Our review of available evaluation literature finds moderately strong evidence that climate services contribute to improvements in food security or its precursors through farmers’ risk management decisions and index-based agricultural insurance; and a weaker body …

An Analysis Of The Impacts Of Climate Change On Food Security In The Albertine Rift Of East Africa, Malcolm Jacob

Sustainability and Social Justice

As one of the most densely populated regions on the continent of Africa, the Albertine Rift (consisting of parts of Rwanda, Uganda, and the eastern DRC) faces ongoing problems providing enough food for its people through crop production, livestock husbandry, and other forms of food production. Even more troubling for the future is that anthropogenic climate change is expected to significantly exacerbate food insecurity. This paper addresses one central question: how will climate change impact food security in the Albertine Rift? Based on an analysis of available data, this paper finds that policymakers should listen closely to local farmers and …

Integrated Approaches To Understanding And Reducing Drought Impact On Food Security Across Scales, Xiaogang He, Lyndon Estes, Megan Konar, Di Tian, Daniela Anghileri, Kathy Baylis, Tom P. Evans, Justin Sheffield

Geography

Understanding the cross-scale linkages between drought and food security is vital to developing tools to reduce drought impacts and support decision making. This study reviews how drought hazards transfer to food insecurity through changes in physical processes and socio-environmental systems across a wide range of spatial and temporal scales. We propose a multi-scale, integrated framework leveraging modeling advances (e.g. drought and crop monitoring, water-food-energy nexus, decision making) and increased data availability (e.g. satellite remote sensing, food trade) through the lens of the coupled human–natural system to support multidisciplinary approaches and avoid potential policy spillover effects. We discuss current scale-dependent challenges …

A High-Frequency Mobile Phone Data Collection Approach For Research In Social-Environmental Systems: Applications In Climate Variability And Food Security In Sub-Saharan Africa, Stacey A. Giroux, Inna Kouper, Lyndon Estes, Jacob Schumacher, Kurt Waldman, Joel T. Greenshields, Stephanie L. Dickinson, Kelly K. Caylor, Tom P. Evans

Geography

Collecting high-frequency social-environmental data about farming practices in sub-Saharan Africa can provide new insight into environmental changes that farmers face and how they respond within smallholder agro-ecosystems. Traditional data collection methods such as agricultural censuses are costly and not useful for understanding intra-annual and real-time decisions. Short-message service (SMS) has the potential to transform the nature of data collection in coupled social-ecological systems. We present a system for collecting, managing, and synthesizing weekly data from farmers, including data infrastructure for management of big and heterogeneous datasets; probabilistic data quality assessment tools; and visualization and analysis tools such as mapping and …

Really Effective (For 15% Of The Men): Lessons In Understanding And Addressing User Needs In Climate Services From Mali, Edward Carr, Sheila Onzere

Sustainability and Social Justice

The design of effective climate services requires the identification of a problem that might be addressed through the provision of weather and climate information, and the design and delivery of actionable information to a set of appropriate users. The utility of weather and climate information for a given user is shaped not only by exposure to particular weather, climate, and market shocks and stresses, but also the sensitivity of that user’s livelihoods to particular shocks and stresses and whether or not their adaptive capacity includes the ability to use such information. Therefore, effective climate services are very place-, time-, and …

The Hartford Food System: A Review Of Assets, Challenges, And Opportunities, Zachary A. Fromson

Sustainability and Social Justice

Abstract

Healthy food systems hold potential to improve a city’s social, health, and economic well-being. Currently, there is a worldwide trend in refocusing food systems to invest in the local community rather than relying on hyper-industrial food value chains that erect barriers for local residents in a city’s food sector. It is the purpose of this report to assess how Hartford’s food sector currently is working so that the city may move in a more innovative direction with its food sector, improving the social, health, and economic conditions for the city and its residents. Thus, this report examines Hartford’s food …

The Gaian-Inspired Systems View Of Life: A Systemic Approach To Global Crises A Case Study: How Scientific Worldviews Influence Global Food Systems, Wyatt Lee Graft

Sustainability and Social Justice

This Master's Paper relies on secondary research in addition to theoretical and philosophical arguments to show that humanity's metaphysical worldview significantly underlies its valuing systems, institutions, and behavior. The paper uses the examples of modern industrial food production and emerging organic and local alternatives to provide a comparative analysis between fundamental worldviews and how they influence the way human systems originate and function. It is argued that the change required to address substantial and interconnected global issues will require a re-evaluation and scrutiny of the metaphysical assumptions inherent in the politics and practice of agriculture, food processing, and the very …

Mapping Cropland In Smallholder-Dominated Savannas: Integrating Remote Sensing Techniques And Probabilistic Modeling, Sean Sweeney, Tatyana Ruseva, Lyndon Estes, Tom Evans

Geography

Traditional smallholder farming systems dominate the savanna range countries of sub-Saharan Africa and provide the foundation for the region's food security. Despite continued expansion of smallholder farming into the surrounding savanna landscapes, food insecurity in the region persists. Central to the monitoring of food security in these countries, and to understanding the processes behind it, are reliable, high-quality datasets of cultivated land. Remote sensing has been frequently used for this purpose but distinguishing crops under certain stages of growth from savanna woodlands has remained a major challenge. Yet, crop production in dryland ecosystems is most vulnerable to seasonal climate variability, …
