Governing Climate Change For Sustainable Food Security In The Busoga Region Of Uganda, James Kintu

Graduate Doctoral Dissertations

Busoga, Uganda's most sugarcane-intensive sub-region, hosts seven mills and an expanding outgrower economy, yet remains among Uganda's most food-insecure areas, with over half of its households food-insecure. This study examined how governance of climate change and sugarcane expansion shapes capabilities for food access, land tenure, and decision-making among women, youth, and land-poor households in Jinja and Buyende.

The study developed an integrated CA-CEP-RFS framework, combining the Capability Approach, Comparative Environmental Politics, and the Resilient Food Systems framework, with Sen's Entitlement Framework bridging capabilities to production, trade, own-labor, and transfer entitlements. A qualitative case study drew on a documentary review, 27 …

Bulletin of Chinese Academy of Sciences (Chinese Version)

Carbon-rich Black Soils are an important natural resource ensuring China’s food security, and their soil carbon stocks are closely related to grain production capacity. Based on nearly two decades of regional survey data and long-term field experiments, this study systematically investigated the dynamics of soil organic matter (SOM), its response relationship with crop productivity, and strategies for soil fertility improvement. The results showed that soil carbon stocks in the topsoil (0–20 cm) of the Black Soil region in Northeast China have declined by approximately 60%. In 2019, the regional average SOM content was approximately 36 g/kg and was decreasing at …

Bulletin of Chinese Academy of Sciences (Chinese Version)

Agricultural modernization is an integral component of the national modernization. Toward 2035, China’s agricultural system confronts multiple challenges, including increasing resource and environmental pressures, rapid upgrading of residents’ consumption structure, and in-depth adjustments in the international supply chain pattern. Meanwhile, it also embraces a series of opportunities brought by transformations in agricultural production technologies and models driven by artificial intelligence, biotechnology, and engineering technology. Based on the perspective of national medium and long-term development strategy, this study sorts out the internal constraints, external opportunities, and development drivers faced by China’s agriculture. It explores six major strategic trends—ecological, intelligent, customized, facility-based, …

Campus Food Recovery: Balancing Sustainability And Student Needs, Scott T. Taylor Jr., Wenhao Zhang, Robin B. Dipietro, Mary Stein, Junehee Kwon

ICHRIE Research Reports

The purpose of this study was to assess the impact of a food recovery program at a large university on food waste reduction and food insecurity mitigation. The primary goal of the food recovery program was two-fold: to help provide ready-to-eat meals for students facing food insecurity and to help the campus food service provider minimize post-production food waste. Thus, food was recovered from multiple dining outlets on a large university campus in the southeast United States. To ensure a valid comparison between 2022-2023 and 2023-2024 academic years, a 3-month period during the spring semesters in 2023 and 2024 was …

Nebraska And The Midwest Agtech Ecosystem: Benchmarking Innovation Investment And Translation Gaps, Ankit Chandra, Ishani Lal, Brennan Costello

Department of Agricultural and Biological Systems Engineering: Presentations and White Papers

Agricultural innovation is central to the sustainable transformation of food systems, yet the capital that finances it is unevenly distributed relative to where food is produced. This paper develops a diagnostic framework for measuring this mismatch and applies it across the U.S. Midwest from 2021 to 2025, with particular emphasis on Nebraska's structural position within this landscape. Drawing on venture capital deal-flow data, 17 stakeholder interviews, and a novel strength-weakness-opportunity-gap (SWOG) ecosystem mapping methodology, we document $736 million in tracked Midwest AgTech funding across eight states (Nebraska, Iowa, Missouri, Illinois, Indiana, Kansas, North Dakota, and South Dakota). We introduce three …

Beyond Emergency: Charting Pathways To Sustainable Development In Fragile And Conflict-Affected Settings: A Case Study Of Yemen, Sharif Abdurabu Salem Farid Alsahbool

Theses and Dissertations

For nearly a decade, Yemen's eastern governorates of Hadramawt, Shabwah, and Al‑Mahrah have been relatively stable, yet the international aid system has kept delivering short‑term humanitarian relief like food baskets and water trucking instead of shifting to sustainable development that could rebuild people's lives, create jobs, fix infrastructure, and strengthen local government. This thesis investigates why this transition has taken so long. Based on 21 interviews with government officials, international NGO staff, and local NGO managers in these three governorates, the study develops a new way of understanding the problem. It introduces three ideas: the 'emergency mentality', which is a …

Crop Yield Shocks And Conflict In Sub-Saharan Africa: Subnational Evidence From Satellite-Based Yield Predictions, Benson I. Adomako

Master's Theses

This paper examines whether crop yields affect violent conflict at the subnational level across seven Sub-Saharan African countries: Burkina Faso, Ethiopia, Mali, Malawi, Niger, Nigeria, and Tanzania, over the period 2010 to 2024. A central identification challenge is that observed yields are endogenous to conflict: armed violence disrupts planting, cultivation, and harvest. To address this, I train a machine learning model on observed maize yield and satellite and environmental features to generate predicted yields for 1,338 second-level administrative districts annually. These predictions serve as the key regressor in a two-way fixed-effects panel with district and year fixed effects. I find …

Spatial Analysis Of Maize Yields And Household Dietary Diversity In Sub-Saharan Africa: Causal Evidence From A Machine Learning Instrument, Addi Joof

Master's Theses

MAIZE YIELDS AND HOUSEHOLD DIETARY DIVERSITY IN SUB-SAHARAN AFRICA: EVIDENCE ON THE CAUSAL EFFECT FROM A MACHINE LEARNING INSTRUMENT

Addi Joof, University of San Francisco, May 2026

This paper provides estimates of the effect of maize yield on household dietary diversity across seven Sub-Saharan African countries, using data from 36,474 maize-growing households in the Living Standards Measurement Study Integrated Surveys on Agriculture (LSMS-ISA) panels for the period 2008--2021. OLS estimates which include district and country-by-wave fixed effects yield a positive and significant coefficient of 0.070 (SE = 0.006, p < 0.001), implying that a 10 percent increase in maize yield raises the Household Dietary Diversity Score (HDDS) by approximately 0.007 food groups. Because self-reported yields are subject to classical measurement error and unobserved household characteristics confound the OLS estimate, we construct an instrumental variable using a Random Forest model trained on satellite-derived agro-environmental features including the Enhanced Vegetation Index, Normalized Difference Vegetation Index, Growing Degree Days, precipitation, and soil moisture obtained from Google Earth Engine at the GPS-coordinate-by-year level. Our preferred 2SLS specification, which adds region fixed effects to absorb persistent sub-national geographic variation, returns a positive point estimate of 0.217 (SE = 0.206; 95% CI: -0.19 to +0.63, p = 0.294) larger than OLS and consistent with downward attenuation bias, but imprecisely estimated and statistically indistinguishable from zero at conventional levels. We interpret the OLS estimate of 0.070 as a credible lower bound on the true effect, with the IV evidence pointing to a moderately larger but uncertain magnitude. Heterogeneity analysis reveals a declining gradient across consumption quintiles the effect is strongest among the poorest households (Q1: 0.055, p < 0.01) and diminishes with wealth (Q5: 0.015, not significant) while showing no gradient across market-integration levels. These patterns are consistent with own-consumption, rather than market income from surplus sales, as the primary pathway from yield to dietary diversity. OLS estimates are positive and significant in five of six estimable countries. The findings suggest that maize yield improvements can serve as a nutrition co-investment, particularly for subsistence-oriented smallholders, though the available data do not permit a sharp causal quantification of the effect size.

Productive Armature, Gabriel Ofem Peter

Masters Theses

What if water was all you had, what if your only source of survival was a body of water? I shudder to think that some people get to be put in this situation in the world we live in. As I understand the importance of water to survival, it is obvious that water can be the only lifeline of survival for a community. This is the experience for residents of Makoko, Lagos. Their survival depends on the Lagos Lagoon, a large body of water flowing in from the Atlantic Ocean. This research looks beyond the surface of what this community …

Learned Resilience, Rebeca Ortiz

Bachelor of Architecture Theses - 5th Year

Haiti faces a complex web of environmental and social pressures, from deforestation and soil erosion to climate instability and strained institutional support. While regenerative farming and community-led development are often discussed in the context of sustainability, architecture is frequently relegated to the background, treated as a secondary or isolated fix rather than a primary driver of change. My work challenges this by positioning architecture as the central, regenerative framework that weaves together food production, collective learning, and civic life. I see the built environment not just as shelter, but as an active agent for resilience and a sense of belonging. …

Scientific Research In Cuba: A General Analysis With A Special Focus On Energy, Agriculture And Technology, Henri Dou, Pierre Fournie

International Journal of Islands Research

An analysis of science in Cuba is carried out using data from the OpenAlex database. Examples are developed: agriculture, rice, technology in relation to the current situation: national food supply, energy and medicine. The predominance of research in biology and medicine and the low commitment in the fields of agriculture, energy, medicinal plants and technology are highlighted. Various development schemes are proposed. The conclusion is that research must be directed towards strategic areas: food and energy, must be less dispersed and that technology must be better taken into account. Three proposals are made: the development of a chemical analysis platform …

Impact Of Climate Change On Agricultural Production In The North China Plain And Adaption Strategies, Yanjun Shen, Ying Guo, Chuanwei Zhang, Yaning Chen

Bulletin of Chinese Academy of Sciences (Chinese Version)

Over the past century, global warming has posed significant challenges to the North China Plain (NCP), a core region for grain production, where resource-induced water scarcity now coincides with complex meteorological disasters. In recent years, the NCP has exhibited new climatic characteristics, notably the transition from a “warm-dry” to a “warm-wet” pattern accompanied by asymmetric warming, leading to an increased frequency of extreme events such as droughts, abrupt dry-flood alternations, and temperature extremes. These shifts pose a grave threat to regional grain stability. Currently, critical gaps remain in the understanding of the underlying disaster mechanisms, as well as in predictive …

Impacts Of Climate Change On China’S Agricultural Production And Proposed Countermeasures, Yaning Chen, Yanjun Shen, Ming Jiang

Bulletin of Chinese Academy of Sciences (Chinese Version)

Climate change is among the most severe global challenges today. It directly impacts agricultural production, which is highly dependent on climatic conditions, imposing multi-dimensional and systemic risks and challenges on China’s agriculture. Drawing on observational data and analysis of the literature, this study systematically examines the impacts of climate change on agricultural production in China. Over the past half century, China’s annual mean surface temperature has risen significantly at a rate of 0.31℃ per decade, exceeding the contemporaneous global average. This trend has intensified climatic variability and extremes, disrupted the prior balance of agricultural water resources, and led to the …

Impacts Of Climate Change On Agricultural Production And Adaptation Strategies In Northeast China, Ming Jiang, Aizhen Liang, Peng Qi

Bulletin of Chinese Academy of Sciences (Chinese Version)

As the “stabilizer” of national food security, Northeast China is highly sensitive to climate change. Over the past 60 years, the regional temperature has risen significantly at a rate of 0.034℃/a, which is much higher than the global average of 0.0074℃/a. The improvement of thermal resources has driven a significant northward expansion of high-yield and heat-demanding crops, such as maize and rice. Nevertheless, increased warming has enhanced evapotranspiration demand, which, combined with the expansion of planting scales, has led to a 19.8% increase in agricultural irrigation water consumption over the past 20 years, resulting in a prominent contradiction between supply …

The Qualitative And Quantitative Analysis Of Fresh Produce Distribution In Rockingham County And The City Of Harrisonburg, Lauren A. Fisher, Alisa Hart

ASPIRE 2026

Fresh produce is essential to a balanced diet; however, many families struggle to access consistent sources of it. In 2022, about 17 million households were without access to nutritionally sound food from an easy to access source (Godoy 2023). About 10% of the populations of Rockingham County (approximately 17,000 people) are considered to be food insecure with at least 1,000 of those being children (Map the Meal Gap 2016).  Many of those experiencing food insecurity rely heavily on the emergency food system (e.g. food pantries).  Highly processed foods tend to be less expensive and shelf stable than the healthier fresh, …

Facilitating Food Security Systems Change In Regional Australia Through A Strengths-Based, Co-Design Process, Isabelle Chiera, Doe, Melissa Stoneham, Amanda Devine, Stephanie L. Godrich

Research outputs 2022 to 2026

Food security is a multifaceted, ‘wicked’ issue that refers to the sufficient physical, social, and economic access to food at all times. Given its complexity, food security action requires a systems-based, collaborative, and adaptive approach. This paper outlines the application of a strengths-based, co-design process to support food security systems change among government and community-led initiatives operating in rural, regional, and remote areas of Western Australia. Baseline, semistructured interviews were conducted with leaders of food initiatives to understand whether and how the initiatives were contributing to food security systems change and identify the ‘windows of opportunity’ where initiatives could be …
