How U.S. Agriculture Adjusts to Energy Price ChangesGong, Jian January 2007 (has links)
The primary objective of this research is to measure the impacts of rising energy prices on U.S. agriculture and to analyze the capability of U.S. agricultural producers to adjust for energy price volatility. This study compares four different models of producer adjustment: the static model, the simple error correction model, the partial adjustment model, and the fully dynamic model. The first three models are nested within the fully dynamic model using ]948-2002 U.S. agriculture data. Morishima elasticities of substitution and price elasticities are estimated to investigate whether U.S. agriculture's responses to energy prices have changed over time. The elasticity estimates indicate that there are substitutions among production factors in U.S. agricultural production, and the substitution elasticities have increased over the 1948-2002 period. This finding suggests an increasing possibility for farmers to substitute other production inputs for energy to mitigate the effects of changing energy prices. / Upper Great Plains Transportation Institute

The Impact of Multilateral Trade Association Membership on Agricultural and Food TradeMcKoy, Shahera Diane January 2007 (has links)
This thesis models trade flows between countries as a function of several variables, including those representing membership in multilateral trade agreements (MTAs). The objective of this research is to evaluate the impact of trade policies, trading costs, trade agreements and other demographic characteristics on exports of food and agriculture products. More specifically, the paper uses a gravity model augmented with three sets of dummy variables to estimate the impact of 13 trade arrangements on intra-bloc and extra-bloc trade. Results indicate that several MTAs enhance intra-bloc trading at the expense of non-members while others have been successful at increasing both intra-bloc trade and trade with the rest of the world. Findings further suggest that several arrangements had no significant effect on member trading and that a few have effectively reduced trade for members.

Examination of North Dakota's Production, Cost, and Profit Functions: A Quantile Regression AnalysisMarroquin, Jacklin Beatriz January 2008 (has links)
This thesis estimates the production, cost, and profit functions for North Dakota agriculture using state-level input-output quantity and price data for the period 1960-2004. A Cobb-Douglas functional form with Hick-neutral technology change is used to measure the contribution of capital, land, labor, materials, energy, and chemical inputs quantities and output quantity using the primal production function; contribution of capital quantity, land quantity, output quantity, labor price, materials price, energy price, and chemical price to cost using the dual restricted cost function; and the contribution of capital quantity, land
quantity, labor price, materials price, energy price, chemical price, output price to profit using the dual restricted profit function. In contrast to previous studies, quantile regression is used to explore the linear or nonlinear relationship between the independent and dependent variable by estimating parameter coefficients at each quantile using time-series data. Empirical findings suggest the cost function is the best model to examine the relationship between input prices, output quantity and cost using quantile regression for North Dakota agriculture, Further, the quantile regression suggests a linear and non-linear
relationship between cost and certain independent variables.

Population genetic structure of small holder dairy cattle herds in South Africa using SNP markersMaake, Mphapantsi Eldred January 2020 (has links)
Thesis (M.Sc. Agriculture (Animal Production)) -- University of Limpopo, 2020 / The smallholder dairy sector in South Africa is characterized by a low input production
system and poor animal productivity. Research has been carried out to benchmark
cow productivity on smallholder dairy herds; however, there is a paucity of information
on the current status of breeding practices and the genetic consititution of cattle used
in this production system. This information is vital for the development of sound and
sustainable breeding programs for SHD production, which can have an enormous
positive impact on food security and rural livelihoods. Thus, the aim of this study was
to evaluate the levels of genetic diversity and population structure in South African
smallholder dairy (SHD) herds using single nucleotide polymorphism (SNP) markers.
A total of 192 animals from SHD dairy herds were genotyped using the GeneSeek®
Genomic Profiler (GGP) 150K-BeadChip. Four specialized dairy breeds included the
Ayrshire(n = 200), Holstein(n = 231), Jersey (n = 224) and Nguni (n = 209) were used
as the reference populations. The mean MAF values ranged from 0.30 Ayshire (AYR),
Jersey (JER), and Nguni (NGI) to 0.31 Holstein (HOL) and SHD between the
populations. There were slight differences in the levels of genetic diversity ranged
between 0.39 (JER and NGI) to 0.40 (AYR, HOL, and SHD). A moderate level of
inbreeding (0.02) was observed in the SHD population, which results in high genetic
diversity among this herds. Principal Component Analysis (PCA) revealed four
homogeneous clusters comprising of AYR, HOL, JER, NGI, and a heterogeneous
cluster of the SHD. The heterogeneity observed in the SHD population indicates
widespread crossbreeding. The model-based cluster analysis corresponded with the
PCA and pointed out the predominance of HOL, JER, with marginal gene flow from
the AYR and NGI. These results have provided a useful insight into the genetic
structure and prevailing breeding practices on South African SHD herds. / National Research Foundation (NRF),

The implementation of sustainable agricultural strategies to alleviate poverty in Topiya village of Emalahleni district municipality in Mpumalanga provinceNdlovu, Robert 29 January 2015 (has links)
A dissertation submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of requirements for the degree of Master of Science. October 2014. / The study seeks to establish how sustainable agriculture can improve livelihoods and consequently alleviate poverty in Topiya community of Mpumalanga Province. The study also entails an investigation into whether the Topiya community is food insecure, and in this instance, how sustainable agriculture can be embraced smoothly to improve the food security status of the Topiya community. The study also seeks to unearth whether raising rural agricultural productivity is sufficient to improve livelihoods or a more robust and multi dimensional approach is needed to improve rural livelihoods in general.
A research instrument (questionnaire) was designed and administered to 19 households. The data is analyzed by way of frequencies and percentages. The results yielded by this study demonstrated that Topiya Community is food insecure and a plethora of factors such as but not limited to lack of adequate arable land, lack of farm assets, lack understanding of the concept of sustainable agriculture contributes to this. The results also pointed to the fact that an intrinsic understanding of what sustainable agriculture entails is of paramount importance for the concept to be embraced and achieve the objectives of improving food security and consequently alleviating poverty.
