DIFERENÇAS DE FINALIDADE E MODIFICAÇÕES ESTRUTURAIS NA FILIÈRE DO ARROZ BIODINÂMICO: O CASO DE SENTINELA DO SUL, RS AgEcon
Hoff, Debora Nayar; Bruch, Kelly Lissandra.
This article aims to study the implications that result from the purpose differences between the biodynamic rice producer systems and the industry of this product in the filière structure. The theoretical approach includes system comprehension and the company vision in the systemic approach, while focusing on the purpose of productive systems according to three possible axles: economic, financial and social. An approach on filière helps in the visualization of the impacts the purpose that system differences studied have on the supplying and industrialization structure of biodynamic rice. A descriptive-comparative research was undertaken based on primary data obtained with the companies and through interviews with owners and managers contacted and on...

Economic impacts of high labour cost and herbicide resistance for the management of annual barnyardgrass (Echinochloa crus-galli) in rice production in the Philippines AgEcon
Beltran, Jesusa C.; Pannell, David J.; Doole, Graeme J..
Implications of increasing labour cost and development of herbicide resistance for profitable weed management in Philippine rice farming systems are investigated. The study employs RIMPhil (Resistance and Integrated Management in the Philippines), a bioeconomic simulation model developed to provide a comprehensive assessment of integrated weed management programmes for the control of annual barnyardgrass (Echinochloa crus-galli) in rice crops. Results indicate that herbicide application will become increasingly economically attractive, relative to manual weeding, as labour cost increases. This is important since urban migration in the Philippines continues to increase the scarcity of rural labour. Results also show that the onset of herbicide resistance...

Livestock Banks and Food Security in Laos AgEcon
Begg, Michael; Santos, Paulo.
The literature analysing the impacts of livestock banks is limited to a small number of papers, mostly of a qualitative nature. This paper contributes to the knowledge on the impacts of this type of intervention on short- term household food security through the analysis of original data form 112 households that participated in a pig bank in Laos. Taking advantage of the staggered implementation of the program, we use propensity score matching the show that receiving pigs reduces household rice production by approximately 34 percent in the first harvest after participation commenced. However, the effects are differentiated across initial wealth status of the beneficiary: if the household was classified as being poor before the start of the program,...

MEASURING THE ENVIRONMENTAL IMPACTS OF TECHNICAL PROGRESS IN LOW-INCOME AGRICULTURE: EMPIRICAL EVIDENCE ON IRRIGATION DEVELOPMENT AND FOREST PRESSURE IN PALAWAN, THE PHILIPPINES AgEcon
Shively, Gerald E..
Data from the Philippines are used to measure impacts of technical progress in lowland agriculture on upland forests. Irrigation development, labor demand, and employment are studied. Total annual labor use increased following irrigation. Employment of household members living along forest margins increased also. Time allocation data from the uplands show that increases in employment among households living along the forest margin were accompanied by reductions in forest clearing and forest-degrading activities. Empirical findings show irrigation-induced increases in agricultural employment can reduce pressure on tropical forests. Implications for policies and trends in use of labor saving methods that could undermine the observed changes are discussed.

Preferences, Norms and Constraints in farmers' agro-ecological choices. Case study using a choice experiments survey in the Rhone River Delta, France AgEcon
Jaeck, Melanie; Lifran, Robert.
The aim of this paper is to elicit the sensitivity of farmers to payments for agro-environmental services in a context of strong agro-ecological and policy constraints. We present results from a choice experiment survey performed among the whole population of agricultural decision-makers (104) in the Camargue area. Several econometric models have been estimated, the most significant being the Latent Classes one. The estimated parameters of the utility function, together with the parameter associated with the monetary attribute provided the monetary value of each relevant agro-ecological attribute and the associated outcomes (average and risk yield).

The Adoption of Water Conservation and Intensification Technologies and Farm Income: A Propensity Score Analysis for Rice Farmers in Northern Ghana AgEcon
Faltermeier, Liane; Abdulai, Awudu.
This study uses cross-sectional data of 342 small-scale lowland rice farmers in Northern Region of Ghana to analyze the impact of the adoption decision of bund construction and seed dibbling on net returns, input demand and output supply. Matching was conducted based on Mahalanobis distance combined with propensity score. Balancing tests by checking the mean standardized absolute bias in the matched sample were conducted as well as sensitivity analysis to check for hidden bias due to unobservable selection. The empirical results of impact assessment using propensity score matching controlling for self-selection bias suggest that input demand is significantly higher for adopters of bunds, but not statistically different for adopters and non-adopters of...
