This paper introduces a spatial bioeconomic model for study of potential cellulosic biomass supply at regional scale. By modeling the profitability of alternative crop production practices, it captures the opportunity cost of replacing current crops by cellulosic biomass crops. The model draws...

We study a farmer’s decision to convert traditional crop land into growing dedicated energy crops, taking in account sunk conversion costs, uncertainties in traditional and energy crop returns, and learning. The optimal decision rules differ significantly from the expected net present value...

Biomass is being researched as a possible alternative to fossil sources of energy, in order to avoid externalities from fossil fuel use that affect the environment and the economy. Some biomass-based energy production systems may produce unwanted externalities in their own right, such as...

In spite of vast expanses of the country’s land currently being uncultivated, there is increasing evidence that a surprisingly high share of rural smallholder households face land constraints that adversely affect their productivity and ability to participate in agricultural supply chains.

Crop income is the predominant source of income for most rural Mozambican households, accounting for 73% of rural household income on average in 2002, and greater than 80% of the total income of the poorest 40% of rural households. While the Government of Mozambique recognizes the need to...

This paper traces the trajectories of successful commercial smallholders operating under differing sets of market institutions. Analysis focuses on maize, cotton, and horticulture, three widely marketed crops with strikingly different market institutions. Maize receives intensive government...

Though Zambia has considerable agricultural potential, the sector’s contribution to growth and poverty reduction has been limited. The sector remains one of the most important employers of labour and remains the main source of livelihood for most rural households in Zambia. Thus key...

Forests support rural livelihoods and food security in many developing countries by providing critical sources of food, medicine, shelter, building materials, fuels, and cash income. The increasing demand for forest products has enhanced rural livelihoods and enabled the expansion of domestic...

A number of problems plague the current Farmer Input Support Programme (FISP), including: late delivery of inputs; distribution of standardized inputs that may not be appropriate for all agro-ecological zones or soil types; crowding out of private sector; poor targeting, and; high cost to the...

Despite being framed as a key component of the nation’s poverty reduction strategy, evidence suggests that inputs distributed under Zambia’s Farmer Input Support Programme (FISP) tend to be targeted to the least poor rural households.
