Increasing homogeneity in global food supplies and the implications for food security

Autor: Khoury, Colin K. Bjorkman, Anne D. Dempewolf, Hannes Ramírez Villegas, Julián Guarino, Luigi Jarvis, Andy Rieseberg, Loren H. Struik, Paul C.

The narrowing of diversity in crop species contributing to the world’s food supplies has been considered a potential threat to food security. However, changes in this diversity have not been quantified globally. We assess trends over the past 50 y in the richness, abundance, and composition of cr...

A participatory epidemiological study of major cattle diseases amongst Maasai pastoralists living in wildlife-livestock interfaces in Maasai Mara, Kenya

Autor: Nthiwa, Daniel Alonso, Silvia Odongo, David O. Kenya, Eucharia Bett, Bernard K.

Livestock-wildlife interactions promote the transmission of a wide range of infectious diseases that constraint livestock production. We used a participatory appraisal approach to find out and rank infectious diseases of concern to pastoralists in a zone of intense wildlife-livestock interaction ...

Quantifying soil carbon stocks and humification through spectroscopic methods: a scoping assessment in EMBU-Kenya

Autor: Segnini, A. Posadas, A. Silva, W.T.L. da Milori, D.M. Gavilan, C. Claessens, Lieven Quiróz, R.

A soil carbon assessment was performed comparing agricultural cropping systems with natural vegetation along a sampling transect spanning different agro-ecologies on the eastern foot slopes of Mount Kenya in Embu county, 125 km from Nairobi, Kenya. The aim was to determine differences in soil car...

Dead wood and saproxylic beetle assemblages in a semideciduous forest in Southern Benin

Autor: Lachat, T. Nagel, P. Cakpo, Y. Attignon, S. Goergen, Georg E. Sinsin, B. Peveling, R.

Saproxylic (dead wood associated) beetles play an important role in all forest ecosystems and are known to be highly susceptible to forest management and fragmentation. Contrary to temperate forests, there has been very little research on saproxylic beetle assemblages in tropical forests. In Afri...

Physicochemical and functional properties of native starches from CMD cassava varieties

Autor: Maziya-Dixon, B.B. Onitilo, M. Sanni, L. Daniel , I.

Pre- and postharvest factors such as genetic factors, environmental conditions during the growth of the plant and the method of starch isolation have been found to have a profound effect on the properties of root and tuber starches. The physicochemical, functional and pas ting properties as well ...

Performance of old and new maize hybrids at high plant densities in the tropical Guinea Savanna

Autor: Kamara, A. Menkir, A. Kureh, I. Omoigui, L. Ekeleme, F.

Genetic improvement of maize hybrids for superior stress tolerance has contributed to increased yield by allowing hybrids to be planted at higher plant populations. This study was conducted to evaluate the response of maize hybrids developed in the Nigerian Savanna from different eras to high pla...

Physicochemical and functional properties of sour starches from different cassava varieties

Autor: Onitilo, M.O. Sanni, L.O. Oyewole, O.B. Maziya-Dixon, B.B.

This article reports our investigation on the effect of cassava varieties on the physicochemical and functional properties of sour starches. There were significant differences (P < 0.05) in the ash, pH, amylose, amylopectin, starch damage, total titratable acidity (TTA), sugar, and starch content...

Farmers perception on the importance of variegated grasshopper (Zonocerus variegatus (L)) in the agricultural production systems of the humid forest zone of Southern Cameroon

Autor: Kekeunou, S. Weise, S.F. Messi, J. Tamo, M.

Zonocerus variegatus (Linnaeus, 1758) (Orthoptera: Pyrgomorphidae) is known as an agricultural pest in West and Central Africa. However, its importance in the agricultural production system in Cameroon has not been investigated. The study assesses farmers' perception on the importance of Z. varie...
