Active Consideration Of Future Health Can Be Prompted By Simple Health Messages And Improves Nutritional Quality Of Food Choices, Christopher R. Gustafson

Department of Agricultural Economics: Faculty Publications

Many choices that people face daily have implications for future health and well-being. Choices about what foods to purchase and consume are one of the most frequent—and universal choices—that people must make. The ongoing rise of overweight and obesity rates—and associated diet-related diseases—in the US and many other countries illustrates the future health consequences of low-quality dietary choices. While a large body of research shows that individuals with a tendency to consider the future make a wide range of healthier decisions, research on limited attention and exogenous factors influencing choice suggests that attention to the future consequences of choices may …

Empowering Women's Land Rights As A Climate Change Mitigation Strategy In Nigeria, Cate Baskin

Northwestern Journal of Human Rights

This article focuses on the intersection between gender and land rights as they relate to climate change in Nigeria. Decisions about land use, such as biodiversity management and farming techniques, impact the quality of the land and peoples’ ability to live off it. This article will show that women are better situated to utilize techniques which sustain the land. Despite this, women have historically been denied land rights in Nigeria, creating a disconnect between the women who cultivate the land and the men who own it and leading to unsustainable use of agricultural land in Nigeria. Climate change is only …

Breeding Sustainable Beef Cows: Reducing Weight And Increasing Productivity, Warren M. Snelling, R. Mark Thallman, Matthew L. Spangler, Larry A. Kuehn

Department of Animal Science: Faculty Publications

Programs for sustainable beef production are established, but the specific role of beef cows in these systems is not well defined. This work characterized cows for two traits related to sustainability, cow weight (CW) and cumulative weight weaned (WtW). Cow weight indicates nutrient requirements and enteric methane emissions. Cumulative weight weaned reflects reproductive performance and avoidance of premature culling for characteristics related to animal health, welfare, and worker safety. Both traits were evaluated with random regression models with records from a crossbred population representing 18 breeds that conduct US national cattle evaluations. The genomic REML analyses included additive and dominance …
