AGRO-BIODIVERSITY AND AGRICULTURAL POLICIES IN AN UNCERTAIN ENVIRONMENT AgEcon
Di Falco, Salvatore; Chavas, Jean-Paul.
Recently, financial assistance to farms has been widely under scrutiny. Agricultural assistance has an important impact on farmers' production decisions and those decisions in turn affect resources use or environmental quality. Surprisingly, the impact of agricultural policies on agro-biodiversity has been relatively neglected. This paper purports a novel framework to analyze the role of crop biodiversity on the mean and the variance of farm revenues. Further, the potential use of this framework in studying the impact of farm financial assistance to crop biodiversity loss is investigated.

COMPARATIVE ANALYSIS OF COST-EFFECTIVENESS OF CO-REGULATORY APPROACHES TO FOOD SAFETY CONTROLS AgEcon
Hussein, Mohamud; Fearne, Andrew; Martinez, Marian Garcia; Di Falco, Salvatore.
Food safety controls are currently enforced in the UK by a variety of regulatory approaches that considerably differ in their efficiency and effectiveness in achieving social goals of safe food supply and improved consumer confidence. Aim of this study is to establish whether a coregulatory enforcement of these controls is more cost-effective than the traditional command-and- control enforcement modes. First of its kind, the study reviewed a vast theoretical literature on economics of food safety and incentives to develop a conceptual framework and appropriate methodology for comparative cost-effectiveness analysis of co-regulatory approaches to food hygiene controls in the UK meat industry. A panel data on costs and compliance of 710 meat firms operating...

Farmer management of production risk on degraded lands: the role of wheat genetic diversity in Tigray Region, Ethiopia AgEcon
Di Falco, Salvatore; Chavas, Jean-Paul; Smale, Melinda.
This paper investigates the effects of wheat genetic diversity and land degradation on risk and agricultural productivity in less favored production environments of a developing agricultural economy. Drawing production data from household survey conducted in the highlands of Ethiopia, we estimate a stochastic production function to evaluate the effects of variety richness, land degradation, and their interaction on the mean and the variance of wheat yield. Ethiopia is a centre of diversity for durum wheat and farmers manage complex variety mixtures on multiple plots. Econometric evidence shows that variety richness increases farm productivity. Variety richness also reduces yield variability but only for high levels of genetic diversity. Simulations with...

ON ADAPTATION TO CLIMATE CHANGE AND RISK EXPOSURE IN THE NILE BASIN OF ETHIOPIA AgEcon
Di Falco, Salvatore; Veronesi, Marcella.
This study investigates the impact of climate change adaptation on farm households’ downside risk exposure (e.g., risk of crop failure) in the Nile Basin of Ethiopia. The analysis relies on a moment-based specification of the stochastic production function. We estimate a simultaneous equations model with endogenous switching to account for the heterogeneity in the decision to adapt or not, and for unobservable characteristics of farmers and their farm. We find that (i) climate change adaptation reduces downside risk exposure, i.e., farm households that implemented climate change adaptation strategies get benefits in terms of a decrease in the risk of crop failure; (ii) farm households that did not adapt would benefit the most in terms of reduction in...

RURAL INSTITUTIONS AND NATURAL RESOURCE EXPLOITATION: THE CASE OF IRISH COMMONAGE AgEcon
Di Falco, Salvatore; van Rensburg, Tom M..
This paper uses an original micro data set, to investigate, the role of a specific rural institutions in determining the grazing regime over a common property resource: Irish Commonage. It is found that the level of communal activity of the shareholders, mismanagement, and the degree of participation or democratic involvement in decision making processes of the committee representing shareholders and the number of people actively using the shares are key variables in explaining grazing impact on the common property resource.

Wheat Diversity and Productivity in Indian Punjab After the Green Revolution AgEcon
Smale, Melinda; Singh, Joginder; Di Falco, Salvatore; Zambrano, Patricia.
The Punjab of India is an historical source of key wheat genetic resources in national and global plant breeding, and a focus of concerns about the abandonment of local varieties during the Green Revolution. Much of the wheat area in Punjab was already planted with earlier products of modern plant breeding programs when the Green Revolution began. These cultivars were more genetically similar and less productive than the semi-dwarf wheat varieties that succeeded them. We define, summarize and test indices of variety change and genetic diversity for the modern wheat varieties released and grown in Indian Punjab during the post-Green Revolution period. The first is the area-weighted average of varieties grown, which measures the rate of variety change,...
