Positive Mathematical Programming to Model Regional or Basin-Wide Implications of Producer Adoption of Practices Emerging from Plot-Based Research

A method for calibrating models of agricultural production and resource use for policy analysis is proposed to leverage multidisciplinary agricultural research at the National Center for Alluvial Aquifer Research (NCAAR). An illustrative example for Sunflower County, MS, is presented to show how plot-level research can be extended to draw systemic region or basin wide implications. A hypothetical improvement in yields for dryland soybean varieties is incorporated into the model and shown to have a positive impact on aquifer outcomes and producer profits. The example illustrates that a change in one practice-crop combination can have system-wide impacts, as evidenced by the change in acreages for all crops and practices.

Positive Mathematical Programming to Model Regional or Basin-Wide Implications of Producer Adoption of Practices Emerging from Plot-Based Research

A method for calibrating models of agricultural production and resource use presented by Howitt [1] for policy analysis is proposed to leverage multidisciplinary agricultural research at the National Center for Alluvial Aquifer Research (NCAAR). An illustrative example for Sunflower County, MS is presented to show how plot-level research can be extended to draw systemic region or basin wide implications. A hypothetical improvement in yields for dryland soybean varieties is incorporated to the model and shown to have a positive impact on aquifer outcomes and producer profits. The example illustrates that a change in one practice-crop combination can have system-wide impacts as evidenced by the change in acreages for all crops and practices.

A Pig and a Garden

Much of the scholarship on the work and legacy of activist Fannie Lou Hamer concentrates on her tireless efforts for civil/human rights and African American representation and access to electoral politics. This chapter brings to light an important project she started in 1969, Freedom Farms Cooperative in Sunflower County, MS. An agricultural cooperative built on 680-acres, Freedom Farm included a pig bank, Head Start program, community gardens, commercial kitchen, a garment factory, sewing cooperative, tool bank, and low-income, affordable housing as strategies to support the needs of African Americans who were fired and evicted for exercising the right to vote. Freedom Farm offered these sharecroppers and tenant farmers educational and re-training opportunities including health care and disaster relief for those who wanted to stay in the Mississippi Delta. Using a historical method to analyze extensive archival records, this chapter offers an analysis of Freedom Farm and illuminates valuable lessons on agriculture as resistance, and alternative strategies of rebuilding and investing in sustainable com- munities. Using the principles of collective and shared ownership, Freedom Farm and the work of Ms. Hamer, offer us important and valuable lessons on rebuilding our communities and investing in sustainable cities around food production.

But If You Have a Pig in Your Backyard … Nobody Can Push You Around

Following its local workshops in the late 1960s, the National Council of Negro Women (NCNW) began to create self-help community programs. This chapter focuses on NCNW's programs in Mississippi--a pig bank for Fannie Lou Hamer's Sunflower County Freedom Farm; low-income home ownership (also known as Turnkey III); and childcare centers in Okolona, Ruleville, and Jackson. To fund these programs, the NCNW utilized financial support from public sources--such as the federal government--and private sources--such as foundations, businesses, and voluntary organizations. Drawing upon its new concept of grassroots expertise as well as the War on Poverty concept of "maximum feasible participation" of the poor, the NCNW recruited local civil rights women such as Fannie Lou Hamer and Unita Blackwell to lead these programs that provided black communities with much-needed food, housing, and childcare. The NCNW's efforts boosted Mississippi women's interest in the larger national organization.

Characterization of Fenoxaprop-P-Ethyl–Resistant Junglerice (Echinochloa colona) from Mississippi

A population of junglerice from Sunflower County, MS, exhibited resistance to fenoxaprop-P-ethyl. An 11-fold difference in ED50 (the effective dose needed to reduce growth by 50%) values was observed when comparing the resistant population (249 g ae ha–1) with susceptible plants (20 g ae ha–1) collected from a different field. The resistant population was controlled by clethodim and sethoxydim at the field rate. Sequencing of the acetyl coenzyme A carboxylase, which encodes the enzyme targeted by fenoxaprop-P-ethyl, did not reveal the presence of any known resistance-conferring point mutations. An enzyme assay confirmed that the acetyl coenzyme A carboxylase in the resistant population is herbicide sensitive. Further investigations with two cytochrome P450 inhibitors, malathion and piperonyl butoxide, and a glutathione-S-transferase inhibitor, 4-chloro-7-nitrobenzofurazan, did not indicate involvement of any metabolic enzymes inhibited by these compounds. The absence of a known target-site point mutation and the sensitivity of the ACCase enzyme to herbicide show that fenoxaprop-P-ethyl resistance in this population is due to a non–target-site mechanism or mechanisms.

Fragments of the American Dream: Immigration, Race, and Medical Care in the Segregated South, 1929

The cover photograph for this issue of Public Voices was taken sometime in the summer of 1929 (probably June) somewhere in Sunflower County, Mississippi. Very probably the photo was taken in Indianola but, perhaps, it was Ruleville. It is one of three such photos, one of which does have the annotation on the reverse “Ruleville Midwives Club 1929.” The young woman wearing a tie in this and in one of the other photos was Ann Reid Brown, R.N., then a single woman having only arrived in the United States from Scotland a few years before, in 1923. Full disclosure: This commentary on the photo combines professional research interests in public administration and public policy with personal interests—family interests—for that young nurse later married and became the author’s mother. From the scholarly perspective, such photographs have been seen as “instrumental in establishing midwives’ credentials and cultural identity at a key transitional moment in the history of the midwife and of public health” (Keith, Brennan, & Reynolds 2012). There is also deep irony if we see these photographs as being a fragment of the American dream, of a recent immigrant’s hope for and success at achieving that dream; but that fragment of the vision is understood quite differently when we see that she began a hopeful career working with a Black population forcibly segregated by law under the incongruously named “separate but equal” legal doctrine. That doctrine, derived from the United States Supreme Court’s 1896 decision, Plessy v. Ferguson, would remain the foundation for legally enforced segregation throughout the South for another quarter century. The options open to the young, white, immigrant nurse were almost entirely closed off for the population with which she then worked. The remaining parts of this overview are meant to provide the following: (1) some biographical information on the nurse; (2) a description, in so far as we know it, of why she was in Mississippi; and (3) some indication of areas for future research on this and related topics.
