Maritime Heritage

Maritime communities and traditions discussed within archaeological discourse, imply either small, contemporary, indigenous communities or folklore traditions from European or North American contexts. The article discusses small-scale tradition and local maritime practices. There are three main strands within this subject—oral histories and folklore traditions, studies of contemporary “traditional” boats, and ethnography that has a maritime locus of study. This article gives a review of these three sources of information on maritime communities and traditions, and addresses the history and context of each research field. Finally, it touches on new directions in studies of maritime communities and traditions, focusing on the notion of maritime heritage. The study of maritime traditions explores the uses to which maritime archaeological knowledge is put in the contemporary world and the cultural and even the socioeconomic politics behind many of the archaeological projects.

Qualitative Changes

In situ grazing is the most common method of feeding crop residues in semi-arid tropical Africa. The prevailing method of storing is to leave the crop residues standing in the field until grazing. Although such field storage would be expected to result in reduced nutritive value (eg loss of leaf), costs of residue harvesting (eg baling) and storing using conventional forage conservation methods would probably be prohibitive to small-scale farmers (Mlay, 1987).There is a dearth of information on quantitative and qualitative changes in crop residues left standing in fields after grain harvesting. A study was therefore carried out at Mpwapwa, Tanzania to measure the effects of varying the duration of field storage upon the quantity and quality of sorghum stover and lablab bean haulm.
