The economic impact of transgenic crops in developing countries: a note on the methods
A vast literature has accumulated since crop varieties with transgenic resistance to insects and herbicide tolerance were released to farmers in 1996 and 1997. A comparatively minor segment of this literature consists of studies conducted by agricultural economists to measure the farm-level impact of transgenic crop varieties, the size and distribution of the economic benefits from adopting them ...

The impact of using GM insect resistant maize in Europe since 1998
Genetically Modified (GM) insect resistant (Bt) maize crops have been grown commercially in the European Union (EU) since 1998, and in 2006, there were plantings in seven EU member states. This paper reviews the specific economic impacts on yield and farm income as well as the environmental impact in respect of insecticide usage (where data exists). The analysis shows that there have been ...

An overview of preharvest factors influencing postharvest quality of horticultural products
Postharvest product quality develops during growing of the product and is maintained, not improved by postharvest technologies. Available genetic material allows discrimination of external and internal quality attributes that must satisfy consumer requirements and indulgences. Farmers face challenges in utilising technologies for producing high quality crops; meaningful manipulation of light, ...

Can genetic engineering help quench crops’ thirst?
Researchers around the world are exploring how GMO technology might boost food production under hot, dry conditions. Roger Deal is trying to figure out how plants remember drought. An assistant professor of biochemistry and genetics at Emory University, Deal says most plants have a kind of memory for stress. When experiencing water shortage, for example, plants close the holes in their leaves, ...

Crop gene banks are preserving the future of agriculture. But who’s preserving them?
As climate change makes crop diversity even more important, gene banks struggle to stay afloat. During the past few years of civil war in Syria, rebel fighters have destroyed Shia mosques and Christian graves, and burned and looted Christian churches while the Islamic State group has demolished priceless artifacts in the region. Nothing seemed sacred to the disparate groups vying for control of ...

Locust Swarms Emphasise the Need for Controlled Environment Agriculture
Outbreaks of locust swarms in Africa, Asia and the Middle East have epitomised the essential need for indoor farming. Unseasonal rains caused by global warming, have aided the spread of desert locusts which would normally have died out in the dry season. Ethiopia and Somalia are currently experiencing their worst outbreak in twenty-five years, while Kenya is experiencing its worst infestation in ...

Mutagenesis, selection, and allelic analysis of epicuticular wax mutants in sorghum
Epicuticular wax forms an outer coating on the aerial surfaces of many crop plants and is implicated in tolerance to several environmental stresses including drought. Advances in knowledge of biosynthesis and secretion of these leaf surface waxes could lead to improvements in crop-stress tolerance. To study the genetics of epicuticular wax deposition, we screened for bloomless (bm) and ...
