Agricultural Commercialization in the Uplands of Northern Vietnam: How to Achieve Both Poverty Reduction and Environmental Sustainability Goals? AgEcon
Keil, Alwin; Saint-Macary, Camille; Zeller, Manfred.
Income growth and urbanization in developing countries have enlarged markets for highvalue agricultural commodities. However, there are concerns that lacking access to physical, financial, and human capital, as well as infrastructure and institutions limit the ability of the poor to participate in and benefit from such commercial agricultural activities. There may further be a trade-off between wealth enhancing effects of intensive commercial agriculture and adverse long-term effects on farmers’ livelihoods due to natural resource degradation. This study provides empirical evidence on these crucial issues and derives related policy recommendations using the example of Vietnam. Here, economic growth has boosted the demand for animal products and,...

Determinants of Farmers' Resilience towards ENSO-Related Drought: Evidence from Central Sulawesi, Indonesia AgEcon
Keil, Alwin; Zeller, Manfred; Wida, Anastasia; Sanim, Bunasor; Birner, Regina.
Crop production in the tropics is subject to considerable climate variability caused by the El Nino-Southern Oscillation (ENSO) phenomenon. In Southeast Asia, El Niño causes comparatively dry conditions leading to substantial declines of crop yields. In concert with global warming, the frequency and severity of the phenomenon are likely to increase during the 21st century. Little is known about the impact of ENSO-related drought on the welfare of farm households in developing countries. This paper seeks to contribute to closing this knowledge gap with a case study from Central Sulawesi, Indonesia. Its objective is to measure household resilience towards drought periods and identify its influencing factors to deduce policy implications. Using...

Drought impacts and related risk management by smallholder farmers in developing countries: evidence from Awash River Basin, Ethiopia AgEcon
Murendo, Conrad; Keil, Alwin; Zeller, Manfred.
Climate risk studies have largely neglected household coping and adaptation strategies. In this paper we analyze drought impacts, drought risk management, and resulting drought resilience in Awash River Basin of Ethiopia based on socio-economic data collected from 43 randomly selected Peasant Associations. We find that severe drought periods have led to a significant depression of crop yields and to widespread death of livestock in the past. Drought periods have drastically increased the proportion of food insecure households and lengthened the duration of food insecurity in the area. Since, with climate change, drought periods are predicted to become more frequent in this region in the future, the problem of food insecurity is likely to become even more...

Land allocation policy and conservation practices in the mountains of Northern Vietnam AgEcon
Saint-Macary, Camille; Keil, Alwin; Zeller, Manfred.
In Vietnam, a quasi-private property regime has been established in 1993, with the issuance exchangeable and mortgageable land use right certificates. Using primary qualitative and quantitative data, this paper investigates the role of the titling policy in fostering the use of soil conservation practices by upland farmers in the northern mountains region. There, population growth and growing market demands have induced farmers to intensify agricultural production onto steep slopes. While poverty has been reduced, environmental 16 problems such as soil erosion, landslides, and declining soil fertility have become severe over the past years. Our findings suggest that soil conservation technologies although relatively well known are perceived as being...

Land titling policy and soil conservation in the uplands of Northern Vietnam AgEcon
Saint-Macary, Camille; Keil, Alwin; Zeller, Manfred; Heidhues, Franz; Dung, Pham Thi My.
Up to 25 percent of all anthropogenic greenhouse gas emissions are caused by deforestation, and Indonesia is the third largest greenhouse gas emitter worldwide due to land use change and deforestation. On the island of Sulawesi in the vicinity of the Lore Lindu National Park (LLNP), many smallholders contribute to conversion processes at the forest margin as a result of their agricultural practices. Specifically the area dedicated to cocoa plantations has increased from zero (1979) to nearly 18,000 hectares (2001). Some of these plots have been established inside the 220,000 hectares of the LLNP. An intensification process is observed with a consequent reduction of the shade tree density. This study assesses which impact carbon sequestration payments for...

Maize boom in the uplands of Northern Vietnam : economic importance and environmental implications AgEcon
Keil, Alwin; Saint-Macary, Camille; Zeller, Manfred.
In Vietnam, the demand for meat products has grown dramatically due to rapid economic growth and urbanisation and is expected to further increase in the future. Being the primary source of feed for the country’s livestock and poultry industry, maize has become the second most important crop after rice. While this maize boom has the potential to reduce rural poverty, it promotes the expansion of agricultural cultivation into fragile agro-ecological zones, often leading to deforestation and soil degradation, especially in the uplands. Using empirical evidence from mountainous Yen Chau district in north-western Vietnam, the objective of this paper is to investigate the current economic importance and environmental implications of maize cultivation....

Mitigating the impact of El Nino-related drought on smallholder farmers in Central Sulawesi, Indonesia: An interdisciplinary modelling approach combining linear programming with stochastic simulation AgEcon
Keil, Alwin; Teufel, Nils; Gunawan, Dodo; Leemhuis, Constanze.
Crop production in the tropics is subject to considerable climate variability caused by the El Niño-Southern Oscillation (ENSO) phenomenon. In Southeast Asia, El Niño causes comparatively dry conditions leading to substantial declines of crop yields with severe consequences for the welfare of local farm households. Using a modelling approach that combines regression analysis with linear programming and stochastic simulation, and integrates climatic and hydrologic modelling results, the objective of this paper is to assess the impact of El Niño on agricultural incomes of smallholder farmers in Central Sulawesi, Indonesia, and to identify suitable crop management strategies to mitigate the income depressions. The results contribute to the formulation of...
