Explaining NDVI trends in northern Burkina Faso
Many studies have shown a ‘greening of the Sahel’ on the basis of analysis of time series of satellite images and this has shown to be, at least partly, explained by changes in rainfall. In northern Burkina Faso, an area stands out as anomalous in such analysis, since it is characterized by a distinct spatial pattern and strongly dominated by negative trends in Normalized Difference Vegetation Index (NDVI). The aim of the paper is to explain this…
Changes in shifting cultivation systems on small Pacific islands
The limited information on change in shifting cultivation systems of small islands of the Pacific stands in contrast to increasing evidence of this farming system's demise in other parts of the tropics. Here, we assess changes in agricultural activities during the past 40 years of Bellona Island, Solomon Islands, where shifting cultivation is still maintained in the traditional way. Fallow length has increased despite population growth due to red…
Continuity and change: Spatiotemporal land use dynamics on Bellona Island, Solomon Islands
Traditional agricultural land use systems in the humid tropics of the Southwest Pacific are, as elsewhere, affected by globalization processes. This paper analyzes the directions of change in the land use system of Bellona, a small outer island in the Solomon Islands. We focus on the human–environmental interaction that shapes land use patterns and practices in the context of theoretical lines of thought concerning intensification of agricultural…
Sustainable land use in Tikopia: Food production and consumption in an isolated agricultural system
The land use system on Tikopia – a Polynesian outlier in Solomon Islands – is analyzed to determine how it has developed since it was first described in the 1930s and again in the 1970s. Fieldwork included a household questionnaire survey, in‐depth interviews on farming practices and decision making, and the collection of soil samples from the major soil and garden types. The Tikopian land use system has not undergone significant changes since th…
Adaptation of Human Coping Strategies in a Small Island Society in the SW Pacific-50 Years of Change in the Coupled Human-Environment System on Bellona, Solomon Islands
Remote sensing techniques for flood monitoring in the Senegal River Valley
Accurate mapping of the aerial extent and duration of yearly flooding of the Senegal River may aid the assessment of the continued viability of traditional flood recession agriculture, as well as the monitoring of hazards to people, irrigated agriculture, buildings and infrastructure. At the same time geomorphologic complexity and expanding rice cultivation requiring dikes and channels make prediction of flooding with hydrological models difficul…

Field Scale Spatial Analysis of pH on Sodium Soils in Northern Burkina Faso
Geografisk Tidsskrift, Danish Journal of Geography 97: 66–75, 1997. Microscale variations of soil properties may have a pronounced impact on crop yields in the low external input agriculture in the Sahel. Using classical and geostatistical methods, spatial patterns of soil pH at 0.0–0.10 m, 0.30–0.50 m and 0.70–0.90 m depth have been analysed and mapped based on two hundred and eighty-one samples collected at 10 m x 10 m grid nodes on a one hecta…
Changes within Small-Scale Agriculture. A Case-Study from the Southwestern Tanzania
Danish Journal of Geography 96: 60–69, 1996. The objective of this paper is through a case study from the southern highlands of Tanzania, to illustrate how the agricultural system has changed within a period from the mid-1950s to the early 1990s in response to both endogenous and exogenous forces. The focus is primarily on the latest response at village level to the liberalization process within the agricultural sector in the early 1990s. New met…
