An efficient hybrid pretreatment method was developed for butanol production from corn stover using dilute sulfuric acid (DA) and aqueous ammonia (AA). With the optimized AA concentration, treatment temperature and time of 10% AA, 80 degrees C and 24 h, the hybrid pretreatment could effectively dissolve hemicellulose and lignin with solid recovery ...

Models of world agriculture and food systems are used widely to predict future scenarios of land and resource uses. Starting with a brief history of world agriculture modelling since the 1960s, this paper demonstrates the hybrid character of these models as well as their limitations in representing real world diversity and options, and presents an ...
We study how the global schooling increase during the 20th century affected structural transformation by changing the supply of agricultural labor. We develop an analytical model of frictional labor reallocation out of agriculture to infer changes in birth-cohort characteristics from observed data on agricultural employment. Bringing the model to m...
The Ferdi and AFD organized a workshop at the AFD in Paris on November 15, 2018, on “Agricultural value chain development and smallholder competitiveness”. Participating institutions to the workshop included Ferdi, AFD, the University of California at Berkeley, Leuven University, CIRAD, IFPRI and the University of Bordeaux, CERDI, the World Bank, t...
A mix of public policy and market interventions in the mid-2000s led to historic reductions in deforestation in the Brazilian Amazon. The collateral impact of these forest conservation policies on agricultural production is still poorly understood, though evidence is sorely needed given the economic importance of agriculture in Brazil and many othe...

How do changes in agricultural productivity affect firms? Using the predictions of a simple multi-sector general equilibrium model of the local economy and exploiting weather-induced agricultural volatility across India, I estimate the response of manufacturing firms to changes in agricultural productivity. I show that negative agricultural product...
Strategies on agricultural management can help to reduce global greenhouse gas (GHG) emissions. However, the potential of agricultural management to reduce GHG emissions at the global scale is unclear. Global ecosystem models often lack sufficient detail in their representation of management, such as tillage. This paper explores whether and how til...
Hai He basin is located in the densely populated North China Plain that is providing food to more than 100 million people. The fast developing agriculture and urbanization in Hai He basin have resulted in discharging nutrient-rich wastewater into lakes and reservoirs, leading to eutrophication and water scarcity such as in Guanting reservoir and Ba...
