Aires marines protégées et récifs artificiels : méthodes d'évaluation, protocoles expérimentaux et indicateurs ArchiMer
Claudet, Joachim.
Marine Protected Areas' (MPAs) and Artificial Reef's (ARs) management requires complex assessment and monitoring programmes, dealing with different sources of variability. We studied and developed experimental designs and analysis methods suited for the establishment of a monitoring of MPAs and ARs. This methodology is developed from existing data sets in the Northwestern Mediterranean. We build multi-criteria indicators allowing a statistically testable diagnosis of the impact of MPAs and ARs on reef fish assemblages. Using ecological performance indicators permits to monitor and to give an image of the assessed system to managers. It was possible to show the global response of the fish assemblages to the protection by a MPA. This response was evidenced...

Assessing the Economic Impacts of Climate Change. An Updated CGE Point of View AgEcon
Bosello, Francesco; Eboli, Fabio; Pierfederici, Roberta.
The present research describes a climate change integrated impact assessment exercise, whose economic evaluation is based on a CGE approach and modeling effort. Input to the CGE model comes from a wide although still partial set of up-to-date bottom-up impact studies. Estimates indicate that a temperature increase of 1.92°C compared to pre-industrial levels in 2050 could lead to global GDP losses of approximately 0.5% compared to a hypothetical scenario where no climate change is assumed to occur. Northern Europe is expected to benefit from the evaluated temperature increase (+0.18%), while Southern and Eastern Europe are expected to suffer from the climate change scenario under analysis (-0.15% and -0.21% respectively). Most vulnerable countries are the...

Does the Participation in the Microcredit Programs Increase Consumption of Participating Households? The Case of the Grameen Bank in Bangladesh AgEcon
Chowdhury, M. Jahangir Alam.
This paper assesses empirically the impact of the participation in the microcredit program of the Grameen Bank on consumption of participating households. A household level survey was carried out for collecting data (N=521). The results of the empirical estimations indicate that the participation of a household in the microcredit program of the Grameen Bank increases consumption of participating households significantly. But there is non-linearity in the increasing trend in consumption of participating households. The consumption level goes up gradually with the increase in the membership duration up to five years of membership, but the growth rate starts declining after that period of membership.

Impact Assessment of Farmer Field School Using A Multi-Period Panel Data Model AgEcon
Praneetvatakul, Suwanna; Waibel, Hermann.
This paper presents an application of a two and three stages difference in differences model to measure environmental and economic impacts of Farmer Field School on crop and pest management practices of rice in Thailand. Panel data from 241 farm households were collected three times over a period of four years in five riceproducing provinces of Thailand. Data included socio-economic data describing household and farm characteristics, rice input and output data including detailed accounts of pesticide use and other pest management practices and farmers' knowledge of crop management and agro ecosystem factors. Using the concept of environmental impact quotient parameters on the health and environmental consequences of a change in pesticide use was computed....

Learning-oriented Evaluation: A tool for promoting institutional learning and program improvement AgEcon
Watts, Jamie.
Evaluation processes of all types, including monitoring, review and impact assessment, offer unique opportunities for learning and provide useful feedback on what works and what doesn’t, and the reasons for success or failure. Involving staff members, partners and beneficiaries in the evaluation process allows them to reflect on their work, revisit their understanding of the project’s goals and activities, assess their effectiveness and take ownership of the evaluation findings. The knowledge created and the lessons learned through evaluation subsequently provide a basis for better project planning and implementation. This Brief outlines an evaluation approach that promotes learning and program improvement; it contrasts this approach with...

THE EFFECT OF TECHNOLOGY TRANSFER PROGRAM PARTICIPATION ON SMALL FARMS IN CHILE AgEcon
Edmonds, Christopher M..
This research examines the effect of a government sponsored technology transfer program for small holder farms in Chile. The effect of family participation in the technology transfer program is evaluated with respect to a number of 'outcomes' including its effect on farm revenues, total family income, and household poverty status. The empirical examination uses maximum likelihood selection and fixed- and random-effects estimation techniques. By estimating the effect of program participation on crop selection, crop yields, farm use of certified seeds, and the scale of farming activities, the research examines the mechanisms through which the program appears to raise farm revenues. Estimation results show program participation had a positive and...
