Income Diversification trough Animal Husbandry for Smallholder Vanilla Farmers in Madagascar
(2020-05-07)
The SAVA region in northeastern Madagascar is the largest vanilla producing area globally. Here, we investigated the role of animal husbandry (AH) for income diversification of small-scale vanilla farmers. To do this, 300 household heads were interviewed about livestock ownership, management and marketing. This information was complemented by data from 1800 households (HHs) on involvement in vanilla production (VP) and AH. Throughout the region, 83 % of HHs produced vanilla and 84 % kept livestock. Chicken-keeping ...

Does the non-farm sector affect production efficiency of the Vietnamese agricultural sector? A stochastic frontier production approach
(2020-12-24)
This study examines the impact of the non-farm sector on farm value-added and production efficiency in the Vietnamese agricultural sector by using data from the Vietnam Household Living Standard Survey 2012. Production function and stochastic frontier production analysis is used to determine the impact, and the instrumental variables method is applied to address endogeneity. We find that the Vietnamese non-farm sector has a positive effect on both farm value-added and efficiency. This result indicates that income ...

Competitiveness of sea buckthorn farming in Mongolia: A policy analysis matrix
(2020-05-09)
Sea buckthorn (Hippophae rhamnoides L.) provides multiple products that are beneficial to human health. In addition, the plant is also used to combat desertification. In contrast to the vast ecological, agronomic and nutritional literature on this species, little is known about its economic and marketing aspects, particularly in Central Asia. We therefore analysed the private and social competitiveness of sea buckthorn farming in 21 households of Bulgan county of Khovd province in Mongolia. The results show that half ...

Spatial variation of nutritional content in Enhalus acoroides (L.f.) royle seeds and seed pods
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2020-04-14)
Coastal and small islands communities generally have limited access to fresh vegetables. The tropical seagrass Enhalus acoroides tends to fruit during the rainy season, when sea conditions often prevent fishing. Coastal communities in several countries, including Indonesia, traditionally collect seagrass fruits for food and traditional remedies. This study measured levels of 6 key nutrients in Enhalus acoroides fruit (seeds and seedpods). Samples were collected from two sites where E. acoroides fruits are harvested ...

A comparison of individual and group behavior in a competition with cheating opportunities
(2020)
While it is well established that individuals and groups make different economic decisions, the reasons for the behavioral differences are still not fully understood. We experimentally compare individual and group behavior in a competitive setting where cheating can be used to outperform the competitor. Our design allows us to exogenously control for the type of the decision maker, the type of the competitor, and whether the competitor is able to cheat or not. The results show that there is much more cheating in ...

The diversity and contribution of indigenous edible fruit plants to the rural community in the Gayo Highlands, Indonesia
(2020-05-15)
The Gayo Highlands offer different indigenous edible fruit species (IEFs) used by the rural community, essentially to provide products such as fruits, oil, medicine, nuts, and fodder. In recent times, these IEFs are being threatened by over-exploitation and biodiversity loss. This study, therefore, aimed to explore the diversity of IEFs and evaluate its contribution to the enhancement of the rural community income in the Gayo Highlands region. The plant materials were randomly collected from nine villages in three ...

Influence of stage of ripening and dietary concentration of Noni (Morinda citrifolia L.) powder on broiler performance
(2020-04-08)
Phyto-additives in poultry diets enhance growth, feed eciency and product quality and minimise the possible risk of residues from chemical additives. There are reports on the use of noni (Morinda citrifolia) fruit powder as phytoadditive in poultry diets but information on the eect of fruit ripening is scanty. Hence, this study compared the eect of unripe and ripe noni fruit owder on broiler performance. A control diet without and 4 diets containing two levels (0.25 and 0.5 %) unripe and ripe fruit powder were fed ...

The effect of edible coating with combined Thymus Vulgaris extract and glycerol monoestearate on oyster mushroom ҆s shelf life
(2020-07-30)
Shelf-life of mushrooms is very low, because of several characteristics, such as their thin epidermal structure and high respiration rates. They tend to lose their quality after harvest. Hence, mushrooms need supportive care to keep freshness. Several protective methods have been recommended. In the current study, the effect of lipid-edible coating with different doses of glycerol monoestearate and thyme extract, for the extending of edible mushroom’s shelf life was evaluated. After, preparation of aqueous thyme ...

Analysis of household food expenditure patterns. A case of Shamva district Zimbabwe
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2020-03-31)
The study was designed to analyse the food expenditure patterns of smallholder farming households. Income and expenditure data were collected from 281 randomly sampled farming households in Shamva District. Descriptive statistics (mean and frequency) were used to analyse the income sources and main expenditure categories. The Ordinary Least Squares regression was used to model the determinants of household food expenditure. The results indicated cash crop, food crop and livestock sales as the major farm income sources. ...

Comparative study on agrochemical residue on rice cultivation in Tasikmalaya, Indonesia: organic versus conventional
(2020-08-12)
This study was designed to examine the agrochemical residue and farmer characteristic strategy in two methods of rice cultivation, organic and conventional. Two groups of farmers were examined, each group (n = 18) with five hectares of land for rice cultivation. This study conducted rapid rural appraisal (RRA) and focus group discussion (FGD), and determined agrochemical residue in water, soil and paddy. The results show that organic rice cultivation has a higher margin of profit at 0.32 USD/kg as compared to ...
