“…In contrast with studies that relate population growth to agricultural land increase in southern Burkina Faso and in dryland ecosystems in general [24,29,51,52], the case of Cassou remarkably shows a stagnating cropland size under increased population. The population density in Cassou has shifted from 23.2 inhabitants/km 2 in 1996 to 34.7 inhabitants/km 2 in 2006 [34,53].…”

Abstract:The present study aimed to detect the main shifts in land-use architecture and assess the factors behind the changes in typical tropical semi-arid land in Burkina Faso. Three sets of time-series LANDSAT data over a 23-year period were used to detect land use changes and their underpinning drivers in multifunctional but vulnerable ecologies. Group discussions in selected villages were organized for mapping output interpretation and collection of essential drivers of change as perceived by local populations. Results revealed profound changes and transitions during the study period. During the last decade, shrub and wood savannahs exhibited high net changes (39% and −37% respectively) with a weak net positive change for cropland (only 2%,) while cropland and shrub savannah exhibited high swap (8% and 16%). This suggests that the area of cropland remained almost unchanged but was subject to relocation, wood savannah decreased drastically, and shrub savannah increased exponentially. Cropland exhibited a null net persistence while shrub and wood savannahs exhibited positive and negative net persistence (1.91 and −10.24), respectively, indicating that there is movement toward agricultural intensification and wood savannah tended to disappear to the benefit of shrub savannah. Local people are aware of the changes that have occurred and support the idea that illegal wood cutting and farming are inappropriate farming practices associated with immigration; absence of alternative cash generation sources, overgrazing and increasing demand for wood energy are driving the changes in their ecosystems. Policies that integrate restoration and conservation of natural OPEN ACCESSLand 2015, 4 561 ecosystems and promote sustainable agroforestry practices in the study zone are highly recommended.

“…Through this market, the area under study becomes an important food crop producer for Niger and Nigeria. Cropland expansion in response to population growth has been previously described in other studies, such as in Turner et al (2011) for Niger, Burgoyne et al (2015) for the Mkuze Game Reserve in South Africa, in Hartter et al (2016) for Uganda and in Ningal et al (2008) for Papua New Guinea.…”

“…Recently a paper was published on population increase and land use change in the Morobe Province of PNG between 1975 and 2000 using GIS (Ningal et al 2008). This study is an example of how GIS can be used to assess and quantify land use changes, planning and resource management.…”

Abstract. National and regional geographic datasets with derivative spatial analysis techniques are often crucial for decision-making in sustainable development for both developing and developed countries. The needs in the spatial data and respective training are demonstrated in this article by the two very diverse examples of Papua New Guinea and the Republic of Lithuania national spatial data infrastructures. Handling and efficient use of geographic data requires rather specific skills. However, the existing curricula are inconsistent and hardly match even the basic needs of geographic information managers in state institutions and municipalities. The main objective of the proposed geographic information e-training system is to develop and provide the modularised Spatial Information Infrastructure courses intended for on-line based learning. This mainly will target employees of civil service and private business in Lithuania and the European Union. The proposed curriculum is a set of modular courses adding up to 1,5-year part-time studies in the field of Geographic Information Science and Geographic Information Infrastructure. Main advantage of on-line-based training is increasing accessibility in terms of both geographic location and time.
