Factsheet of the month: October 2015 – Grain storage in metal silos against insect pests

20157800264Last week, 193 Member States of the United Nations adopted the new Sustainable Development Agenda to end poverty by 2030. This came at the beginning of a three-day Summit on Sustainable Development during which focussed on implanting changes that will see the Agenda achieve its ambitious aims. The Agenda, consisting of 17 Sustainable Development Goals (SDG), will help countries to develop their policies over the next 15 years.

The second SDG on the list is to “End hunger, achieve food security and improved nutrition, and promote sustainable agriculture.” Globally, 1 in 9 people are undernourished, the majority of whom are in developing countries where food loss is an important factor. Food loss is the food that gets spilled or spoilt before it reaches its final product or retail stage, whereas food waste happens at the retailer or consumer stage. Continue reading

Introducing APHLIS: The African Postharvet Losses Information System


Plantwise have recently been investigating APHLIS data, a great source of information on postharvest losses in Sub-Saharan Africa.  The system is run by a network of local experts who collect and supply data.  Using a shared database and a Losses Calculator APHLIS provide estimates of weight losses for cereal grains at a national and provincial level.  Continue reading

Why food losses are even greater than the Global Food report by IMechE says

Yesterday saw the release of a report from the Institution of Mechanical Engineers which highlighted the shocking level of waste within the global food system.

The report, ‘Global Food – Waste not, want not’, claims 30-50% (or 1.2-2bn tonnes) of all food produced is wasted. In the context of a rapidly growing global population this amount of waste simply isn’t acceptable. The report also notes the waste that lies behind the front-line statistics. For each item of food wasted the resources which have gone towards producing it are wasted too. In a world of water shortages and energy crises this inefficiency can be devastating.

Despite its strengths, the report is limited in one respect. It fails to examine the entire food production process and does not take into account one of the biggest causes of food waste – pre-harvest crop losses. Although the report notes that “frequently poor weather conditions or attacks by pests of all types reduce the quality or quantity of crop harvested” it fails to properly account for the huge global losses which occur.
