Prospects for growth and poverty reduction in Zambia, 2001-2015 por Lofgren, Hans, Thurlow, James, Robinson, Sherman

“…This paper uses a computable general equilibrium (CGE) model to assess the potential impact on inequality and poverty of the key PRSP policies, as well as the effects of foreign debt forgiveness and changes in the copper sector. The findings suggest that, in the absence of very rapid growth, the pro-poor policies outlined in the PRSP will not enable Zambia to reach its Millennium Development Goal (MDG) of halving poverty by 2015. …”

Physical and virtual global food reserves to protect the poor and prevent market failure por von Braun, Joachim, Torero, Máximo

“…The current food crisis has several causes—rising demand for food and feed, biofuels, high oil prices, climate change, stagnant agricultural productivity growth—but there is increasing evidence that the crisis is being made worse by the malfunctioning of world grain markets. …”

How does food price increase affect Ugandan households?: An augmented multimarket approach por Ulimwengu, John M., Ramadan, Racha

“…Overall, we found that household welfare is expected to decrease with loss in consumption and increase with income gain as a result of higher food prices for the cereals producers. Simulating change in cereals consumption induced by a 50 percent increase in cereals price and taking into account the profit effect, our results predict a 23 percent decrease in food consumption for net sellers, compared with 44 percent when using the consumption approach alone. …”

Productivity convergence in Brazil: The case of grain production por Magalhaes, Eduardo C., Diao, Xinshen

“…We first apply a generalized entropy (GE) method to assess whether inequality in productivity has changed over time. The entropy analysis indicates that the trends for overall entropy did not increase over time for all three crops. …”

Zero tillage in the rice-wheat systems of the Indo-Gangetic Plains: A review of impacts and sustainability implications por Erenstein, Olaf

“…Zero tillage’s impact has been achieved through an intervention that has proven privately attractive; an enabling process that combined elements of persistence, flexibility, inclusiveness, and facilitation; and a context that implied the need for change. To replicate and extend this success, viable and dynamic innovation systems should be developed that can deliver and adapt interventions such as zero tillage. …”

Technology adoption under seed access constraints and the economic impacts of improved pigeonpea varieties in Tanzania por Shiferaw, Bekele A., Kebede, Tewodros A., You, Liangzhi

“…Even under restrictive assumptions, overall discounted benefits were found to be quite attractive, indicating the need for additional efforts to scale‐up the success story. Analysis of changes in research benefits from relaxing the seed access constraint showed that net gains would increase by up to 30% if farmer access to improved seeds can be assured. …”

No significant changes were observed in plant and ear height over the study period. …”
