Uncovering Biogas Outcomes: Tales of Hubris, Hope, and Failure From Southern Malawi

Natural Resources Forum, EarlyView.
ABSTRACT The purpose of this article is to speak directly to biogas failure. Over the past two decades, immense amounts of money have been spent by African governments, private individuals, and most conspicuously, international aid agencies and donors, on countless biogas projects in every country on the continent.

Intra‐Seasonal Crop Management and the Potential Benefit of Seasonal Precipitation Forecasts: Farm‐Level Embedded Risk Analysis in Ethiopia

Journal of Agricultural Economics, EarlyView.
ABSTRACT How large is the potential benefit for farmers from obtaining forecasts of total rainfall in the upcoming season? This critically depends on the local farm system and the crop management actions available to farmers to respond to the forecasts issued. Studies assessing the financial value of seasonal precipitation forecasts have so far focused

Efficiency, Shadow Pricing and Regime Switching in Multi‐Ware Technologies: Evidence From Regulated Livestock Farms

Journal of Agricultural Economics, EarlyView.
ABSTRACT We develop a framework for regulated production systems where output generation and pollution abatement impose competing technological demands. Using a multi‐ware technology, we model the production set as the intersection of two input requirement frontiers, one for production and one for abatement, each reflecting distinct trade‐offs.

Fertilising Climate Policy: The Dual Impact of CBAM on EU Agricultural Emissions and Regional Disparities

Journal of Agricultural Economics, EarlyView.
ABSTRACT The Carbon Border Adjustment Mechanism (CBAM), scheduled to become fully operational in 2026, is designed to complement the EU Emissions Trading System (ETS) by replacing free emission allowances and preventing carbon leakage to non‐EU regions. CBAM initially covers energy‐intensive sectors, including mineral nitrogen (N) fertiliser production.

An Economic and Environmental Analysis of Virtual Fencing for Precision Grazing

Journal of Agricultural Economics, EarlyView.
ABSTRACT The UK grazing livestock sector is challenged by declining farm profitability and stringent environmental policy. Innovative technologies such as virtual fencing could enable a balanced economic and environmental performance of beef production. Virtual fencing is a livestock management tool relying on invisible boundaries perceived as auditory,
