Aquaculture is the fastest growing food sector and continues to expand alongside terrestrial crop and livestock production. Using portfolio theory as a conceptual framework, we explore how current interconnections between the aquaculture, crop, livestock, and fisheries sectors act as an impediment to, or an opportunity for, enhanced resilience in the global food system given increased resource ...
The paper surveys the price competitiveness of agricultural production in Central and East European Countries (CEECs). It draws together empirical work conducted by the authors and other studies that have estimated domestic resource cost (DRC) ratios for agriculture in various CEECs. The paper identifies that in general CEEC crop production is more internationally competitive than livestock far...
Agriculture could be one of the most vulnerable economic sectors to the impacts of climate change in the coming decades, with impacts threatening agricultural production in general and food security in particular. Within this context, climate change will impose a challenge to policy makers, especially in those countries that based their development on primary sectors. In this paper we present a...
Weather and climate events and agronomic enterprise are coupled via crop phenology and yield, which is temperature and precipitation dependent. Additional coupling between weather and climate and agronomic enterprise occurs through agricultural practices such as tillage, irrigation, erosion, livestock management, and forage. Thus, the relationship between precipitation, temperature, and yield i...
INTRODUCTION In Zambia, agriculture continues to be an important source of livelihood, supporting about 70% of the population. The country’s agriculture sector is dominated by small scale rural farmers, who largely depend on rain for crop production, mainly due to the absence of irrigation equipment in most rural communities. Thus any change in climate, mostly manifested as an increase in frequ...
Agriculture is a sector easily affected by meteorological conditions. Crop yield reduction, even regional conflicts, may occur during a drought. It is extremely important to improve the state of our knowledge on agricultural drought risk. This study has proposed a new method (vulnerability surfaces) for assessing vulnerability quantitatively and continuously by including the environmental varia...
The first-generation transgenic cotton (Gossypium hirsutum L.), Bollgard, which contains a single toxin protein gene cry1Ac from Bacillus thuringiensis var. kurstaki Berliner, was approved by the National Biosafety Committee (NBC) for commercial growing in Pakistan in 2011 and the yield enhancement is promising, with an increase in cotton bales up to 150 millionthe record productivity of the co...
Land management practices affect the long term sustainability of agricultural soils. Growing Forward, Agriculture and Agri-Food Canada’s (AAFC) agricultural policy framework, has identified promoting environmentally responsible agriculture as one of the department’s priorities. Land management information requirements have become increasingly important to a number of programs and policies suppo...
Proponents of Jatropha curcas portrayed the crop as a 'sustainable biofuel' that was less threatening to food security and forests than other energy crops, creating a reputation that helped jatropha projects to multiply quickly throughout the global South. However, many jatropha initiatives failed to thrive and ultimately collapsed. This paper investigates how actors involved with jatropha in K...
The ability to monitor and control plant nutrient ions in fertigation solutions, on an ion-specific basis, is critical to the future of controlled environment agriculture crop production, be it in traditional terrestrial settings (e.g., greenhouse crop production) or as a component of bioregenerative life support systems for long duration space exploration. Several technologies are currently av...
