Socio-economic aspects of irrigation agriculture as livelihood for rural families in Brazil’s semi-arid northeast
(2019-12-04)
Along the lower-middle São Francisco River, in the semi-arid region of northeast Brazil, irrigated agriculture contributes to reduce rural poverty. In the framework of the Itaparica Reservoir construction, three irrigation schemes were implemented in the Pernambuco state to compensate the local population for flooded land. Despite favourable production conditions for irrigated agriculture, many smallholders in the irrigation schemes are facing poverty. To identify socio-economic key indicators on farm income, expert ...

Effect of Sowing Method and Weed Control on the Performance of Maize (Zea mays L.) Intercropped with Climbing Beans (Phaseolus vulgaris L.)
(2017-06-23)
Maize is grown on a large area in Germany and there is a growing concern in society about negative environmental effects related to this. The objective of the study was to test the performance of mixtures of maize and climbing beans as an alternative to monocropped maize under different site and management conditions. The effects of sowing density of maize and beans as well as the sowing time of beans on total dry matter (DM) yield and bean DM contribution to the total yield were investigated. Further, various ...

Nutritional Comparison of White and Red Coccinia Abyssinica (Lam.) Cong. Accessions: An Under-Utilised Edible Tuber of the Ethiopian Highlands
(2017-08-22)
Anchote (Coccinia abyssinica) is an indigenous tuber crop of the Ethiopian Highlands. It is popular in the western Oromia Region of the country. Apart from food, the crop is also used in traditional medicine. Anchote tubers possess two variations in its tissue colour, red and white. In this study, a small market survey and a nutritional comparison of red and white anchote were conducted. White tissue anchote seems to be more popular, due to its soft texture and ease of cooking. However, the red variant was considered ...

Biological control in pest management in Turkey: Comparison of the attributes of participant and non-participant greenhouse farmers in government-subsidized biological control practices
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2019-11-29)
The adoption of biological control methods is increasing in crop production due to concerns and awareness of consumers about food safety and pesticide residue conundrum. Biological control methods are a key component in pest management practices as they minimize the usage of pesticides, hence create less environmental and health problems. Biological control practices have been supported in Turkey since the year 2010 to ensure economical greenhouse production and to reduce the consumption of pesticides for sustainable ...

Sustainable rural development in Ukraine: Legal aspect
(Section Specialized Partnerships in Sustainable Food Systems and Food Sovereignty at the University of Kassel, Germany and Federation of German Scientists (VDW), 2018-12-26)
Sustainable rural development involves the attainment of a balanced development of the economic, ecological and social spheres within a community. For this purpose, the state agrarian policy should be aimed at achieving three goals: 1) food security of the state; 2) solving of social and environmental problems in rural areas; and, 3) the transformation of the agrarian sector into a highly effective, competitive domestic and foreign market economy sector of the state. Therefore, the purpose of the article is to study ...

Competitive interaction between guava and weeds: Effect on initial growth
(2019-12-03)
Guava (Psidium guajava L.) is one of the 50 most consumed fruits in the world. However, weed competition compromises fruit production in cultivation areas. Thus, this work aimed to evaluate the competitive interaction between guava plants and common infesting species on initial growth. Guava seedlings were cultivated during 60 days with Bidens subalternans DC., Waltheria indica L. or Commelina benghalensis L. in a randomized block design with four replicates. The experiment was conducted under greenhouse condition ...

Strategies towards evaluation beyond scientific impact
(Librello, 2015)
Various research fields, like organic agricultural research, are dedicated to solving real-world problems and contributing to sustainable development. Therefore, systems research and the application of interdisciplinary and transdisciplinary approaches are increasingly endorsed. However, research performance depends not only on self-conception, but also on framework conditions of the scientific system, which are not always of benefit to such research fields. Recently, science and its framework conditions have been ...

Biofuels and livelihoods: Empirical findings on the welfare impacts of Jatropha cultivation in the Mangochi district, Southern Malawi
(2019-11-27)
This study evaluates the welfare impacts of jatropha (Jatropha carcus) cultivation measured as consumption expenditure per adult-equivalent for smallholders in southern Malawi. Household survey data from the southern region of Malawi collected in 2014 from 303 smallholders using purposive and random selection strategies were used. Propensity score matching and endogenous switching regression methods were employed to address the selection bias problem and to control for observed and unobserved covariate effects. The ...

Heavy Metals and Polycyclic Aromatic Hydrocarbons in Urban Leaf Litter Designated for Combustion
(2017-03-03)
Vast amounts of leaf litter have to be disposed of by city administrations. This biomass has the potential for energy conversion, but contamination with pollutants can adversely affect this usage. We investigated leaf litter samples from the city of Kassel by analyzing their heavy metal and polycyclic aromatic hydrocarbon (PAH) concentrations. Leaf samples were indeed contaminated with heavy metals and PAHs and contamination was influenced by provenience and collection technique. A simple cleaning system of washing ...
