Energetic but jobless: socio-economic and
institutional drivers of youth unemployment in the Okavango Delta, Botswana, Prof Oluwatoyin
Dare Kolawole and Onkarabile Kemiso
Abstract: Unemployment, inequality and poverty are the
scaffoldings which conspicuously mirror the impediments to development in any
human society. Of the three, joblessness or unemployment serves as the hinge on
which other challenges rest. Thus the paper assesses the factors contributing
to rural youth unemployment in the Okavango Delta, Botswana. It specifically
analyses socio-economic and institutional factors influencing rural youth
unemployment in the study area. A multi-stage sampling procedure was used to
sample 105 youths aged between 18-35 years in two communities within the Okavango
Delta area. Open and close-ended questionnaires were administered to elicit
information from the respondents. We summarised the data obtained using
descriptive statistics. We then used inferential statistical tools such as
correlation and regression analyses to test the relationship between youth
unemployment and selected explanatory variables embedded in socio-economic and
institutional factors. A non-parametric test was also conducted using Chi
square analysis to determine the associations between the dependent and nominal
variables investigated. The findings show that most of the youths (57.1%) were
unemployed (57.1%) of which 65.6% of the jobless individuals constituted the
female respondents. Regression analysis indicates that level of education (t =
-2.133; p ≤ 0.05); training (t = 3.831; p ≤ 0.000); access to
information (t = 2.349; p ≤ 0.05); acquisition of entrepreneurial skills
(r = 0.388; p ≤ 0.000) and youth perceptions towards government
programmes (t = 1.744; p ≤ 0.10) are significant variables influencing
rural youth unemployment in the study area. Chi square analysis also shows that
gender (X2 = 4.815; p ≤ 0.05) had a significant
association with youth unemployment. Thus education, training, and access to
relevant information are crucial policy issues for alleviating rural youth
unemployment in the Okavango Delta, Botswana.
Behaviour-related scalar habitat use by Cape buffalo
(Synerus caffer)- Dr Emilly Bennitt
Abstract: Studies of habitat use by animals must consider
behavioural resource requirements at different scales, which could influence
the functional value of different sites. Using Cape buffalo (Syncerus caffer
caffer) in the Okavango Delta, Botswana, we tested the hypotheses that
behaviour affected use between and within habitats, hereafter referred to as
macro- and microhabitats, respectively. We fitted GPS-enabled collars to
fifteen buffalo and used the distances and turning angles between consecutive
fixes to cluster the resulting data into resting, grazing, walking and
relocating behaviours. Distance to water and six vegetation characteristic
variables were recorded in sites used for each behaviour, except for
relocating, which occurred too infrequently. We used multilevel binomial and
multinomial logistic regressions to identify variables that characterised
seasonally-preferred macrohabitats and microhabitats used for different
behaviours. Our results showed that macrohabitat use was linked to behaviour,
although this was least apparent during the rainy season, when resources were
most abundant. Behaviour-related microhabitat use was less significant, but
variation in forage characteristics could predict some behaviour within all
macrohabitats. The variables predicting behaviour were not consistent, but
resting and grazing sites were more readily identifiable than walking sites.
These results highlight the significance of resting, as well as foraging, site
availability in buffalo spatial processes. Our results emphasise the importance
of considering several behaviours and scales in studies of habitat use to
understand the links between environmental resources and animal behavioural and
spatial ecology
Strategic management of livestock to improve
biodiversity conservation in African savannas: a conceptual basis for
wildlife-livestock coexistence, Dr
Richard Fynn
Summary
1. African savannahs are complex socio-ecological
systems with diverse wild and domestic herbivore assemblages, which utilize
functional heterogeneity of habitats to adapt to intra- and inter-annual
variation in forage quantity and quality, predation and disease risks.
2. As African savannahs become increasingly fragmented by
growing human populations and their associated ecological impacts, adaptive
foraging options for wild and domestic herbivore populations are
correspondingly limited, resulting in declining wildlife populations and
impoverished pastoral societies. In addition, competition for grazing by
expanding domestic herbivore populations threatens to reduce functional
heterogeneity by homogenizing grassland structure, and reducing the viability
of wild herbivore populations occupying similar grazing niches.
3. Conservation initiatives are further impacted by
conflicts between wildlife and local communities of people who often receive
little benefit from adjacent protected areas, creating conflict between the
livelihood-orientated goals of communities and the conservation-oriented goals
of the international community and those with vested interests in wildlife.
Conservation strategies facilitating the alignment of these opposing goals of
communities and conservationists are needed.
4. Synthesis and applications. Key to
understanding facilitative and competitive interactions between wild and
domestic herbivores are the concepts of niche differentiation and functional resource
heterogeneity. Uncontrolled incursions of burgeoning domestic herbivore
populations into protected areas threatens the conservation of wild herbivore
biodiversity. However, domestic herbivores can be managed to minimize
competition with wild herbivores and to enhance habitat by maximizing grassland
structural heterogeneity (greater adaptive foraging options), creation of
nutrient hotspots in the landscape and facilitation of high-quality grazing.
Ecosystem service benefits to communities through controlled access to grazing
resources in protected areas, associated with appropriate disease management,
can provide a conservation payment to promote communities’ support of
conservation of key wildlife migratory ranges and corridors outside protected areas.
