Shoot Cadmium Accumulation of Maize, Sunflower, Flax, and Spinach as Related to Root Physiology and Rhizosphere Effects
(2011-03-22)Plants differ widely in Cd accumulation when grown on Cd contaminated soils. This is because several soil properties interact with several plant properties. Plant factors determining the ... -
Shrub encroachment of temperate grasslands: Effects on plant biodiversity and herbage production
(2009-12-10)In Europe, semi-natural grasslands are an important resource of biodiversity and are, therefore, of high conservation interest. They are often invaded by shrubs, and they are threatened by ... -
Sicherheitsforschung und Monitoringmethoden zum Anbau von Bt-Mais: Expression, Nachweis und Wirkung von rekombinantem Cry1Ab in heterologen Expressionssystemen
(2005-04-11)The cropping of genetically modified plants, for example Bt-corn, has raised concerns on their potential ecological risks. In order to recognise their potential effects on nature and ... -
Site-specific adaptation by natural selection. A case study with lentil.
(2018-04-10)In the context of conservation and use of plant genetic resources, both storage in gene banks (ex situ) and safeguard on-farm (in situ) are important concepts. Increasingly attention focuses on the on-farm management of ... -
Small-scale raspberry producers’ risk and ambiguity preferences, and technology adoption: empirical evidence from rural Maule, Chile
(2017-02-22)Most researchers who analyze producers’ preferences under uncertainty report that producers are averse towards risk and ambiguity scenarios. This aversion has an influence on producers’ decision-making processes; hence the ... -
Smallholders in highland regions of Southeast Asia: Agricultural land-use transitions, farmer risk preferences, the effects of poor vision on economic farm performance, and a note on scientific publishing in the field of development studies
(2023-06-27)Smallholders play an important role in feeding a growing world population and contributing to the eradication of hunger and poverty. It is estimated that there are more than 475 million smallholders in the world and recent ... -
Social Network Patterns of Sharing Information on Land Use and Agricultural Innovations in Ethnically Heterogeneous Communities in Ecuador
(2014-03-03)A case study in South Ecuador serves as an example to understand the dynamics of adoption of agroforestry species. Agroforestry species become important in land that is totally devoid of forest cover. They can reduce soil ... -
Social Networks, Technology Adoption and Technical Efficiency in Smallholder Agriculture: The Case of Cereal Growers in Central Tanzania
(2015-04-02)Global demand for food and agricultural products is on the rise. There is hence the need to increase production to meet this growing demand and smallholders will play a significant role. One strategy for smallholders to ... -
Social Services, Water Access, and Agricultural Productivity in Sub-Saharan Africa
(2012-11-19)In sub-Saharan Africa, public resource allocation in social service sectors can be particular important in that low levels of development can make private services inaccessible for much of the population. In addition, ... -
Social standards, worker welfare and women's empowerment in modern agri-food systems: A case study of horticultural wage workers in Ghana
(2017-06-27)The world agricultural trade system has experienced tremendous changes in recent years. Agri-food systems are increasingly shifting towards more vertically integrated production systems that are based on commercialization ... -
Social-Ecological Preferences and Urbanization in India
(2019-05-15)Urbanization has been recognized as one of the major forces in shaping the 21st century on planet earth. The by far largest increase in the share of humans living in cities is expected to take place in the Global South. ... -
Sodium and calcium uptake, transport and allocation in Populus euphratica and Populus x canescens in response to salinity
(2008-02-15)The salinization of soils caused by increasing NaCl concentrations is a major problem for today’s agriculture. Since P. euphratica is able to grow on sodic soils, it has been used for reforestation in saline areas. Because ... -
