    In terms of economic empowerment, agribusiness can act as an engine of livelihood enhancement, playing a fundamental role in promoting agricultural households to engage in value addition. Project results reveal that trained women and youths statistically and significantly participate in poultry keeping, goats rearing and trade, especially in farm produce. After training, participants significantly participated in growing millet, sweet potatoes, cassava, cow peas, beans, groundnuts, choroko, tomatoes, and citrus. Results also provide justification for education and/or training in agribusiness activities, which should include improved farming practices and crops that can provide agibusiness potential in a particular region

    A posteriori error covariances in variational data assimilation

    Get PDF
    The problem of variational data assimilation for a nonlinear evolution model is formulated as an optimal control problem to find some unknown parameters of the model. The equation for the error of the optimal solution is derived through the statistical errors of the input data (background, observation, and model errors). A numerical algorithm is developed to construct an a posteriori covariance operator of the analysis error using the Hessian of an auxiliary control problem based on tangent linear model constraints
