TitelIndividual risk attitudes in rural Thailand and Vietnam
ForschungszieleThis project aims for generating a better understanding of the role of individual risk attitude in explaining economic behaviour of poor households as a pre-requisite for empirical research to build up a considerable database serving the specific needs of research.
The project has four objectives, namely: (1) to validate various measures of individual risk attitude in the cross-section, (2) to generate understanding about the determinants of risk attitude in the time-series, (3) to analyze the influence of financial literacy, and (4) to analyze the role of risk attitude of agricultural decision makers together with their past experience and their level of knowledge on management decisions in agriculture.
MethodologieA representative household survey in rural areas of Thailand and Vietnam will be conducted.
The resulting database provides comprehensive information about characteristics of these households, including about all kinds of shocks and risks and the respondent individual risk attitudes.

TitelStatus of markets for organic and fair trade commodities in agriculture and its impact for developing countries: A meta-analysis
ForschungszieleOverall objectives: To assess the extent to which certified alternative agricultural systems like organic agriculture and fair trade management can contribute towards sustainable livelihoods of smallholder farmers in developing countries.
Specific objectives:
  • To examine the drivers that influence the adoption of such alternative farming systems;
  • To investigate the extent to which organic and fair trade certified agriculture impacts production and welfare of smallholder farmers;
  • To compare and do a meta-analysis on how these systems effects smallholder farmers in the continents on Asia, Africa and Latin America and derive the success factors of such farming technologies.
MethodologieEconometric and meta-analysis based on secondary and primary data.

TitelImproving the management of trypanosomiasis in smallholder livestock production systems in tsetse-infested sub-Saharan Africa
ForschungszieleOverall objectives:
To improve the sustainable livelihoods of resource-poor livestock producers in smallholder production systems through improved control of trypanosomiasis.
Special objectives:
  • To improve capacity and capability of African laboratories and veterinary services to detect trypanocide resistance  and to conduct quality control of trypanocidal drugs;
  • To improve the effectiveness of available trypanocides in livestock;
  • To promote and monitor the use of the technical and structural innovations developed in partnership at a regional and continental scale.

TitelInsurance and Private Transfers – Experimental Evidence
ForschungszieleMost people in developing countries are currently not insured; they therefore depend on private transfers from relatives and friends when hit by a shock. However, the provision of insurance is steadily increasing. An important question is to what extent the possibility to purchase insurance affects the willingness to help others. Previous research shows contradicting effects: some studies find a decrease in private transfers, others an increase. The underlying drivers remain unclear. Guided by the literature on other-regarding preferences, the proposed project investigates potential mechanisms that may help explain changes in helping behavior.
MethodologieWe analyze these mechanisms in a framed field experiment combined with a household survey on transfer behavior within social networks. We conduct the project in several villages in Cambodia.

TitelSustainable rubber cultivation in the Mekong region (SURUMER), sub-project 9: Microeconomic analysis of sustainable Natural Resources Management innovations in rubber cultivation in Yunnan Province, China
ForschungszieleThe main objective of this project is to establish a better understanding of the potential to introduce a sustainable rubber plantation system in Yunnan province in Southwestern China. To achieve this objective an ex-ante impact analysis of sustainable Natural Resource Management (NRM) innovations of farmers in this area will be carried out.

Specific objectives:
1. Analyze different adoption decisions by using econometric models to identify key factors that drive smallholder rubber farmer’s decision.
2. Conduct a comprehensive economic analysis of different farming systems (rubber monoculture, intercropping, traditional agriculture), giving account of the cost structures, productivity, cash income generation and poverty levels.
3. Conduct an economic impact assessment by use of a “difference-in-difference model” and “normative household models” based on the concept of typical farms.
4. Investigate the potential economic effects of alternative land use strategies in terms of income generation, income inequality, food security, and poverty and vulnerability reduction.
5. Analyze the barriers and required incentives for small-scale farmers to adopt economically sustainable land use and management concepts.

Conduct empirical analysis by using econometric models and collected data

TitelCost-benefit analysis of sustainability standards in small holder oil palm farming in Sumatra, Indonesia
ForschungszieleThis research aims to assess the acceptance and economic consequences of standards for sustainable oil palm farming among small holders in the province of Jambi, Sumatra, Indonesia.
This study will draw from an existing panel data set of some 291 small holder oil palm farmers from 2010 and 2012 in two districts of Jambi.
Three hypotheses will be tested:
(1) smallholder oil palm farmers are aware of the environmental standards promoted by the Government in oil palm plantations;
(2) the benefits of sustainable oil palm management practices are uncertain;
(3) woman can play a major role in implementing sustainable oil palm management practices.
Fieldwork to test the first hypotheses has already been conducted during July - August 2012.
For 2013, additional data collection is proposed with the objective to test the second and the third hypotheses. Individual interviews, focus group discussions with village groups and a stakeholder workshop will be conducted to establish the empirical base for developing and applying cost benefit analysis.
