development of a suitable method for color sorting of agricultural products such as: tomato, apple and orange, based on surface reflection and image formation was the goal of this research. a suitable scheme of color differentiation using an optic head and electrical processing circuitry for separating red from green and other colors is presented. a photo-conductive transducer, electrical resis...

investing in research and development spending (r&d) affects total factor productivity (tfp).recently new theories of economic growth have emphasized the relationship between r&d and tfpand also identified a number of channels through which a country’s r&d affects tfp of its tradepartner. this study seeks to estimate the effect of agricultural r&d and education spending and some...

BACKGROUND Sustainability in Agriculture In order to meet future needs of a growing human population and to achieve food security in the context of climate change, food production will likely need to increase—among other measures—while at the same time minimizing negative environmental impact (Foley et al., 2011). Sustainable intensification of agriculture (Garnett et al., 2013; Pretty and Bhar...

The participants at the food summit organized by the Food and Agriculture Organization (FAO) in 1996 pledged to reduce the number of hungry by half by 2015. Measuring and quantifying food insecurity is a crucial component of making progress towards that goal. This paper presents one possible approach towards measuring what share of the population might be affected by food insecurity and to what...

We also wish to acknowledge the FAO Netherlands Partnership Programme-supported project, " Using markets to promote the sustainable utilization of crop genetic resources", some of whose materials on crop genetic resources we have drawn upon here.

There is evidence that pollinators are declining as a result of local and global environmental degradation [1-4]. Because a sizable proportion of the human diet depends directly or indirectly on animal pollination [5], the issue of how decreases in pollinator stocks could affect global crop production is of paramount importance [6-8]. Using the extensive FAO data set [9], we compared 45 year se...
