Sood, AdityaSeidou, O.Forkuor, G.Annor, F.O.McCartney, Matthew P.[Simulating current and future Volta Basin water development scenarios]Simulating current and future Volta Basin water development scenarios

The study was conducted to estimate model parameters of Incomplete Gamma (IG) (b=1) and Inverse Polynomial ¢P) functions of a lactation curve and the models lactation yield prediction potential based on milk data from Bako Agricultural Research centre and Debre Zeit Research Station. The models w...


Gebreyohannes, G.Tegegne, AzageDiedhiou, M.L.Hegde, B.P.[Estimated model parameters of incomplete gamma and inverse polynomial functions and comparison of the models lactation yield prediction potential in Zebu and crossbred cattle]Estimated model parameters of incomplete gamma and inverse polynomial functions and comparison of the models lactation yield prediction potential in Zebu and crossbred cattle

A software package to generate daily weather data for Latin America and Africa is described. The program is based on a stochastic weather generator that uses a third-order Markov process to model daily weather data. The model has been fitted to data from more than 9200 stations with long runs of ...


Jones, Peter G.Thornton, Philip K.[MarkSim: Software to generate daily weather data for Latin America and Africa]MarkSim: Software to generate daily weather data for Latin America and Africa

Data augmentation is a powerful technique for estimating models with latent or missing data, but applications in agricultural economics have thus far been few. This paper showcases the technique in an application to data on milk market participation in the Ethiopian highlands. There, a key impedi...

East Africa contains areas with some of the greatest large mammal biodiversity on the planet. These areas are key natural resources for the economic development of the region. They are also key areas for pastoralists who have co-existed with wildlife for millennia. Increasing populations, conflic...


Thornton, Philip K.Galvin, K.A.Boone, Randall B.[An agro-pastoral household model for the rangelands of East Africa]An agro-pastoral household model for the rangelands of East Africa

This study develops and demonstrates procedures for modeling the impact of agricultural technology adoption decisions on consumption and nutrition in a subsistence-farming context. The method is based on expected direct utility maximization (EDUM) formulation and incorporates subsistence quantiti...


Ahmed, M.M.Preckel, P.Baker, T.G.López Pereira, M.[Modeling the impact of technological change on nutrition and marketed surplus]Modeling the impact of technological change on nutrition and marketed surplus

A dynamic model of Schistosoma japonicum transmission is presented that incorporates effects of infection intensity, age, and sex. We use four infection intensity classes to investigate the impact of ecologic changes and public health interventions on the burden of infection within communities. A...


Riley, S.Carabin, H.Marshall, C.Olveda, R.Willingham, A.L.McGarvey, S.T.[Estimating and modeling the dynamics of the intensity of infection with Schistosoma japonicum in villagers of Leyte, Philippines. Part II: Intensity-specific transmission of S. japonicum. The schistosomiasis transmission and ecology project]Estimating and modeling the dynamics of the intensity of infection with Schistosoma japonicum in villagers of Leyte, Philippines.

Crossbreeding parameters for milk production and reproductive traits and for cow live weight (LW) of crosses of Ayrshire (A), Brown Swiss (B), Friesian (F) and Sahiwal (S) cattle were estimated using data from a dairy herd in the lowland coastal tropics of Kenya. An individual animal model was fi...


Kahi, A.K.Thorpe, W.R.Nitter, G.Baker, R.L.[Crossbreeding for dairy production in the lowland tropics of Kenya. I. Estimation of individual crossbreeding effects on milk production and reproductive traits and on cow live weight]Crossbreeding for dairy production in the lowland tropics of Kenya. I. Estimation of individual crossbreeding effects on milk production and reproductive traits and on cow live weight
