“…The task of increasing or maintaining the productive capacity of soils under cultivation has become one of the greatest challenges to farmers in SSA (Adamtey, 2010;Adamtey et al, 2009). Although composting is gaining high recognition among farmers in SSA, the process is long (3 to 4 months), affecting the cost of production, availability and quality (nitrogen content) (Adamtey et al, 2009;Danso et al, 2006).

This paper reviews entomophagy as practised in Africa within the context of food and nutritional security by providing an inventory of the various species of insects that are consumed on the continent and suggests a research for development (R4D) agenda for sustainable utilisation of insects for food and feed. Our survey showed that over 470 species of insects are eaten in Africa. The Central African region remains the most important hotspot of having a culture of entomophagy. The insects mostly eaten in the continent are dominated by the orders Lepidoptera, Orthoptera and Coleoptera. Commonalities were observed across the majority of the insects consumed across Africa, providing opportunities for related R4D activities. An R4D agenda and pathways for using edible insects suggest that socio-economics and marketing studies should address issues of communities' perceptions, based on their cultural background, income and beliefs. Cost-effective rearing, harvesting and processing technologies are required to prevent depletion and ecological perturbations while ensuring continuous availability of insect-based products. Indigenous reports assert that some edible insects harbour medicinal properties; thus, the need to undertake nutritional and bioactive chemical characterisation of main edible insects along the value chain and to investigate food safety issues such as diseases, allergies, and toxicological and chemical hazards. The use of insects for waste conversion into animal feed and fertiliser requires judicious choice of substrate in view of concerns regarding contaminant loads and pathogens occurrence. Responding to these research needs and opportunities, icipe has recently established an Insects for Food, Feed and Other Uses Programme with well-defined work packages oriented towards attainment of its Vision and Strategy 2013-2020 document, with a strong orientation towards R4D and a focus on activities that lead to adoption and impact on end users, through broad based complementary linkages and partnerships with agriculture and livestock extension services, Food and Agriculture Organization of the United Nations, Consultative Group on International Agricultural Research and advanced research institutes, non-governmental organisations and the private sector.

“…Enrichments in composting improve nutritive value; augment disease suppressive activity and beneficial microbial populations in the composts (Postma et al 2003;Biswas and Narayanasamy 2006;Pugliese et al 2011;Diaz et al 2011;Singh and Amberger, 1995;Nishanth and Biswas 2008;Biswas 2011;Meena and Biswas 2014). Such enriched composts partly substitute mineral fertilizer requirements (Adamtey et al 2009), improve soil organic matter stocks, augument soil quality and most importantly prevent loss of nutrient N through volatilization (DeLaune et al 2004;Steiner et al 2010).…”

“…In India, compost application is an age‐old practice for better yield and the potential of compost in soil fertility improvement has been demonstrated in India 1, 6 and elsewhere 7. However, it may be mentioned here that usually total nitrogen (TN) content in compost is low 8, 9. Therefore, additional input(s) is/are necessary to make it equivalent to inorganic fertilizers.…”

Composts with five different ratios of agricultural wastes, viz. rice straw (RS), wheat straw (WS), potato plant (PP), and mustard stover (MS) were prepared with or without fish pond bottom sediment to investigate the compost maturity and their suitability for field application. The composting process was monitored through the changes in physico‐chemical parameters and germination index (GI) at every 7 days interval of the composting process. All the composts were dark brown and smelled like forest soil within 56 days of composting, which reflected its matured status. On the basis of the physico‐chemical parameters (bulk density: 0.84 g/cm3; pH 7.05; electrical conductivity: 3.52 mS/cm; cation exchange capacity:82.4 cmol/kg; total carbon:321.4 g/kg; total nitrogen: 16.9 g/kg; As: 6.8 mg/kg; Cd: 2.96 mg/kg; Cr: 29.6 mg/kg, Cu: 243.6 mg/kg; Hg: 0.019 mg/kg; Ni: 24.3 mg/kg; Pb: 62.1 mg/kg and Zn: 812 mg/kg) and GI (89–96%), it could be concluded that RS/WS/PP/MS, 1:1:2:1 v/v/v/v with fish pond sediment produced better compost in accordance with the Indian compost standard. Application of a combined randomized block design analysis revealed that there is a significant difference in the responses of the five composts, in relation to the time of composting. Hierarchical clustering algorithm was applied with a view to form homogeneous groups of five different composts on the basis of different physico‐chemical parameters. Therefore, the ratio of waste incorporation is an important decision for composting and addition of pond sediment can improve the quality of compost.
