The time and energy required of women for cultivation and harvesting, food processing and preparation as well as the fetching of fuel and water rarely figure in national labour statistics. Per capita availability of eggs increased from five eggs per head per annum at one time to 55 eggs per head per annum in The production of oilseeds, though has increased in recent years from High-yielding replacement varieties of B.

Often landholdings which are too small to provide a tolerable livelihood have been turned into part-time farms, with some household members usually the women and children staying at home to tend crops while others often the men migrate in search of wage employment.

Why are annual crop species at such an advantage? The USA data show no impact of a lack of pollinators on production Figs in the three bee-requiring families examined here, with many crops showing large increases in yield over the 51 years even though, at the same time, USA honey production has halved The steps taken to defend the gains already made should therefore include pest surveillance and management and gene deployment for checkmating the spread of pathogens.

The genetics are not in doubt. While calculating food requirements, the needs of farm animals are often overlooked. A country's ability to feed itself very much depends on three factors: Clearly the relative rates of change in crop yields over time and crop importance are related.Chapter 8: Production Decline Analysis.

Bee decline, pollination and food production. Summary There are widespread concerns that falling honey bee numbers will lead to food shortages. This view is not universally accepted and further information is needed to determine future directions to reduce the potential impact of bee decline.

capita cereal production is an important indicator of food availability, especially in large landlocked regions with large agrarian populations, a restriction that applies to most. Dramatic decline in industrial agriculture could herald 'peak food' Food production will need to increase by about 60% by to meet demand.
