    Securing the World and Challenging Civil Society: Before and After the ,War on Terror'

    DEVELOPMENT AND CHANGE, Issue 2 2010
    Jude Howell
    ABSTRACT Following President Bush's declaration of a ,War on Terror' in 2001, governments around the world introduced a range of counter-terrorist legislation, policies and practices. These measures have affected not only human rights and civil liberties but also civil society and aid frameworks. Although the Obama administration has renounced the language of the ,War on Terror' and taken steps to revoke aspects such as water-boarding and the detention facility at Guantanamo Bay, the bulk of the legislation and practices associated with the post-9/11 global security framework remain. The cluster of papers which follow provide detailed studies of the effects of the War on Terror regime on civil society in four contexts: the USA, Spain, Kenya and Uzbekistan. In this way it lays a basis for civil society actors and aid agencies to reflect more strategically on how they should engage with security debates and initiatives in a way that best protects the spaces of civil society and the interests of minority and vulnerable groups. This introduction sets out the three key themes pursued throughout the cluster articles, namely, the selective impact of counter-terrorist measures on civil society; the particularity of civil society responsiveness to these measures; and the role of aid and diplomacy in pursuing security objectives and its consequences for civil society.

    Challenging Orthodoxies: Understanding Poverty in Pastoral Areas of East Africa

    DEVELOPMENT AND CHANGE, Issue 4 2008
    Peter D. Little
    ABSTRACT Understanding and alleviating poverty in Africa continues to receive considerable attention from a range of diverse actors, including politicians, international celebrities, academics, activists and practitioners. Despite the onslaught of interest, there is surprisingly little agreement on what constitutes poverty in rural Africa, how it should be assessed, and what should be done to alleviate it. Based on data from an interdisciplinary study of pastoralism in northern Kenya, this article examines issues of poverty among one of the continent's most vulnerable groups, pastoralists, and challenges the application of such orthodox proxies as incomes/expenditures, geographic remoteness, and market integration. It argues that current poverty debates ,homogenize' the concept of ,pastoralist' by failing to acknowledge the diverse livelihoods and wealth differentiation that fall under the term. The article concludes that what is not needed is another development label (stereotype) that equates pastoralism with poverty, thereby empowering outside interests to transform rather than strengthen pastoral livelihoods.

    ,Milking The Elephant': Financial Markets as Real Markets in Kenya

    DEVELOPMENT AND CHANGE, Issue 2 2004
    Susan Johnson
    Financial liberalization policies in the 1990s were intended to raise formal sector interest rates, enhance competition and expand access for users. This article investigates patterns of provision and use in a local financial market in Karatina, Kenya, at the end of the 1990s after a period of financial and economic liberalization. It takes a holistic approach, examining both formal and informal financial arrangements and microfinance interventions. This is because the role of the informal financial sector is particularly important for poor people and has received relatively little attention in the discussion of the consequences of reform. The author does this using a ,real' markets approach that sees markets as socially regulated and structured. Significant provision by the mutual sector (formal and informal), and poor lending performance by the banking sector is explained through an examination of the characteristics of the services on offer and their embeddedness in social relations, culture and politics.

    Elites, Rent-Cycling and Development: Adjustment to Land Scarcity in Mauritius, Kenya and Côte d'Ivoire

    DEVELOPMENT POLICY REVIEW, Issue 4 2010
    Richard M. Auty
    According to rent-cycling theory, low rent aligns the interests of the elite and the majority in providing public goods and efficiency incentives to promote economic growth, while high rent risks deflecting the elite into self-enriching rent deployment, which distorts the economy and triggers a collapse from which recovery is protracted because rent recipients resist reform. The theory also predicts, however, that this collapse will self-correct by shrinking per capita rent, which strengthens incentives for wealth creation. This article tests the prediction in Mauritius, Kenya and Côte d'Ivoire where intensifying land scarcity has shrunk per capita rent; Mauritius meets the prediction, but Kenya and Côte d'Ivoire do not.

    Never the Twain Shall Meet: A Memetic Analysis of Poverty Perceptions

    DEVELOPMENT POLICY REVIEW, Issue 2 2009
    Federica Misturelli
    Poverty, as defined within development discourse, does not fully capture the reality in which the poor live, which is formed also by values and beliefs specific to a given culture and setting. This article uses a memetic approach to investigating the reality of poverty among pastoralists and urban dwellers in Kenya. By distinguishing the semantic space and the cultural context in which the definitions are framed, it enables the researcher to make sufficient generalisations while also recognising the differences between cultures. The results demonstrate how pastoralists and urban dwellers conceptualise poverty differently particularly in regard to causes. Further, the article suggests that development actors often utilise a Western construct which does not entirely reflect the values and beliefs of the poor. [source]


    The Machakos Case Study: Solid Outcomes, Unhelpful Hyperbole

    DEVELOPMENT POLICY REVIEW, Issue 1 2006
    Jules Siedenburg
    This article revisits the well-known study of Machakos District, Kenya reported in the book More People, Less Erosion by Tiffen et al., which found dramatic, compelling evidence of successful endogenous adaptation to changing circumstances by rural Africans. The article seeks to elucidate discrepancies between the Machakos findings and other findings in the interest of both scientific accuracy and policy relevance. It is suggested that the Machakos study comprises hopeful data, on the one hand, and problematic calculations and assertions, on the other. After exploring problems with the study, the article suggests an alternative interpretation of the data that is arguably more pertinent to contemporary concerns with rural poverty and environmental degradation as well as more widely applicable in sub-Saharan Africa.

    The Rise of Kenyan Supermarkets and the Evolution of their Horticulture Product Procurement Systems

    DEVELOPMENT POLICY REVIEW, Issue 6 2004
    David Neven
    Supermarkets are rapidly penetrating urban food retail in Kenya and spreading well beyond their initially tiny market niche among the urban middle class into the food markets of lower-income groups. Having penetrated processed and staple food markets much earlier and faster than fresh foods, they have recently begun to make inroads into the fresh fruits and vegetables category. Supermarkets in Kenya already buy about half the volume of produce exported, and thus represent a significant new ,dynamic market' opportunity for farmers. The important changes in their procurement systems bring significant opportunities and challenges for small farmers, and have implications for agricultural diversification and rural development programmes and policies.

    The role of weight for age and disease stage in poor psychomotor outcome of HIV-infected children in Kilifi, Kenya

    DEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 12 2009
    AMINA ABUBAKAR PHD
    Aim, We aimed to investigate the contribution of disease stage and weight for age to the variability in psychomotor outcome observed among children with human immunodeficiency virus (HIV) infection. Method, This cross-sectional study involved 48 Kenyan children (20 females, 28 males) aged 6 to 35 months (mean 19.9mo SD 8.9) exposed prenatally to HIV. Two subgroups of HIV-exposed children were seen: those who were HIV-infected and those who were uninfected. The reference population was composed of 319 children (159 females, 160 males) aged 6,35 months, (mean age = 19 months, SD=8.43) randomly selected from the community. Disease stage varied from stage 1 to stage 3, reflecting progression from primary HIV infection to advanced HIV infection and acquired immune deficiency syndrome. A locally developed and validated measure, the Kilifi Developmental Inventory, was used to assess psychomotor development. Result, Using age-corrected psychomotor scores, a significant main effect of HIV status was observed (F(2,38.01)=7.89, p<0.001). Children in the HIV-infected group had lower mean psychomotor scores than the HIV-exposed children and the reference group. In the HIV-infected group, disease stage was a negative predictor and weight for age a positive predictor of psychomotor outcome. Interpretation, Weight for age and disease stage provide viable, easily measurable benchmarks to specify when frequent developmental monitoring and psychomotor rehabilitation are required. Nutritional intervention and other measures aimed at slowing disease progression may delay the onset and severity of psychomotor impairment in the paediatric HIV population in Africa. [source]


    Severe falciparum malaria and acquired childhood language disorder

    DEVELOPMENTAL MEDICINE & CHILD NEUROLOGY, Issue 1 2006
    Julie A Carter BSc (Hons) MSc PhD
    Language disorders have been reported after severe falciparum malaria but the deficits have not been described in detail. We assessed language outcome in three groups of children aged 6 to 9 years (n=487): those previously admitted to Kilifi District Hospital, Kenya, with cerebral malaria (CM; n=152; mean age 7y 4 mo [SD 1y 1mo]; 77 males, 75 females); or those with malaria and complicated seizures (M/S; n=156; mean age 7y 4mo [SD 1y 2mo]; 72 males, 84 females); and those unexposed to either condition (n=179; mean age 7y 6mo [SD 1y 1mo]; 93 males, 86 females). Median age at hospital admission was 28 months (interquartile range [IQR] 19 to 44 mo) among children with a history of CM and 23 months (IQR 12 to 35mo) among children with a history of M/S. A battery of eight assessments covering the major facets of speech and language was used to measure language performance. Cognitive performance, neurological/motor skills, behaviour, hearing, and vision were also measured. Eighteen (11.8%) of the CM group, 14 (9%) of the M/S group, and four (2.2%) of the unexposed group were found to have a language impairment. CM (odds ratio 3.68,95% confidence interval 1.09 to 12.4, p=0.04) was associated with significantly increased odds of an impairment-level score relative to the unexposed group. The results suggest that falciparum malaria is one of the most common causes of acquired language disorders in the tropics. [source]


    Changing household responses to drought in Tharaka, Kenya: vulnerability, persistence and challenge

    DISASTERS, Issue 2 2008
    Thomas A. Smucker
    Drought is a recurring challenge to the livelihoods of those living in Tharaka District, Kenya, situated in the semi-arid zone to the east of Mount Kenya, from the lowest slopes of the mountain to the banks of the Tana River. This part of Kenya has been marginal to the economic and political life of Kenya from the colonial period until the present day. A study of more than 30 years of change in how people in Tharaka cope with drought reveals resilience in the face of major macro-level transformations, which include privatisation of landownership, population growth, political decentralisation, increased conflict over natural resources, different market conditions, and environmental shifts. However, the study also shows troubling signs of increased use of drought responses that are incompatible with long-term agrarian livelihoods. Government policy needs to address the challenge of drought under these new macro conditions if sustainable human development is to be achieved. [source]


    Destocking as a Drought,mitigation Strategy: Clarifying Rationales and Answering Critiques

    DISASTERS, Issue 3 2002
    John Morton
    The idea of externally assisted emergency destocking of pastoralists has gained currency in recent years: increasing the incentives for pastoralists to sell animals, or removing the constraints to selling animals in the early stages of drought. We identify two separate rationales put forward by proponents of destocking: environmental benefits and purchasing power/welfare benefits. We consider whether specific recent critiques of ,new range ecology' and specifically of ,tracking policies' do in fact provide arguments against emergency destocking in pastoralist areas. We illustrate some of these themes with a case study of a successful destocking exercise in northern Kenya where a very specific form of support was requested and received by pastoralists themselves. The sorts of destocking that work are likely to have significant effects on pastoralist purchasing power at key points of the drought cycle, but minimal effects on the environment. Clarifying these points will make it easier to promote destocking as a drought,mitigation policy. [source]


    Can distribution models help refine inventory-based estimates of conservation priority?

    DIVERSITY AND DISTRIBUTIONS, Issue 4 2010
    A case study in the Eastern Arc forests of Tanzania, Kenya
    Abstract Aim, Data shortages mean that conservation priorities can be highly sensitive to historical patterns of exploration. Here, we investigate the potential of regionally focussed species distribution models to elucidate fine-scale patterns of richness, rarity and endemism. Location, Eastern Arc Mountains, Tanzania and Kenya. Methods, Generalized additive models and land cover data are used to estimate the distributions of 452 forest plant taxa (trees, lianas, shrubs and herbs). Presence records from a newly compiled database are regressed against environmental variables in a stepwise multimodel. Estimates of occurrence in forest patches are collated across target groups and analysed alongside inventory-based estimates of conservation priority. Results, Predicted richness is higher than observed richness, with the biggest disparities in regions that have had the least research. North Pare and Nguu in particular are predicted to be more important than the inventory data suggest. Environmental conditions in parts of Nguru could support as many range-restricted and endemic taxa as Uluguru, although realized niches are subject to unknown colonization histories. Concentrations of rare plants are especially high in the Usambaras, a pattern mediated in models by moisture indices, whilst overall richness is better explained by temperature gradients. Tree data dominate the botanical inventory; we find that priorities based on other growth forms might favour the mountains in a different order. Main conclusions, Distribution models can provide conservation planning with high-resolution estimates of richness in well-researched areas, and predictive estimates of conservation importance elsewhere. Spatial and taxonomic biases in the data are essential considerations, as is the spatial scale used for models. We caution that predictive estimates are most uncertain for the species of highest conservation concern, and advocate using models and targeted field assessments iteratively to refine our understanding of which areas should be prioritised for conservation.

    Gully-head erosion processes on a semi-arid valley floor in Kenya: a case study into temporal variation and sediment budgeting

    EARTH SURFACE PROCESSES AND LANDFORMS, Issue 9 2001
    D. J. Oostwoud Wijdenes
    Abstract A three year monitoring programme of gully-head retreat was established to assess the significance of sediment production in a drainage network that expanded rapidly by gully-head erosion on the low-angled alluvio-lacustrine Njemps Flats in semi-arid Baringo District, Kenya. This paper discusses the factors controlling the large observed spatial and temporal variation in gully-head retreat rates, ranging from 0 to 15 m a,1. The selected gullies differed in planform and in runoff-contributing catchment area but soil material and land use were similar. The data were analysed at event and annual timescales. The results show that at annual timescale rainfall amount appears to be a good indicator of gully-head retreat, while at storm-event timescale rainfall distribution has to be taken into account. A model is proposed, including only rainfall (P) and the number of dry days (DD) between storms: which explains 56 per cent of the variation in retreat rate of the single-headed gully of Lam1. A detailed sediment budget has been established for Lam1 and its runoff-contributing area (RCA). By measuring sediment input from the RCA, the sediment output by channelized flow and linear retreat of the gully head for nine storms, it can be seen that erosion shifts between different components of the budget depending on the duration of the dry period (DD) between storms. Sediment input from the RCA was usually the largest component for the smaller storms. The erosion of the gully head occurred as a direct effect of runoff falling over the edge (GHwaterfall) and of the indirect destabilization of the adjacent walls by the waterfall erosion and by saturation (GHmass/storage). The latter component (GHmass/storage) was usually much larger that the former (GHwaterfall). The sediment output from the gully was strongly related to the runoff volume while the linear retreat, because of its complex behaviour, was not. Overall, the results show that the annual retreat is the optimal timescale to predict retreat patterns. More detailed knowledge about relevant processes and interactions is necessary if gully-head erosion is to be included in event-based soil erosion models. Copyright © 2001 John Wiley & Sons, Ltd.

    Exotic plant species invade diversity hot spots: the alien flora of northwestern Kenya

    ECOGRAPHY, Issue 2 2000
    J. Stadler
    We analysed the distribution of native and alien plant species across 20 ecogeographic zones of northwestern Kenya. The source pool for the majority of aliens was Europe and America. Thus, the source pool has a biogeographic bias which explains the low proportion of aliens in the tropics: most species in the European or American source pool are not well adapted to tropical conditions. As expected, native and alien plant species showed an area effect. Correcting for this area effect. species rich zones showed a higher proportion of alien plant species in their flora. At the analysed scale, species richness of native plant communities does not increase the resistance to invasions and alien plant species invade diversity hotspots. Compared to the other ecogeographic zone, the urban area around Nairobi showed an increased richness in alien and native plant species. This is very similar to findings in Europe, although the history of urbanisation is much shorter in Kenya. The species turnover between zones (,-diversity) shows a similar pattern in native and alien plant species. Within a very short time scale the alien plant species mapped the biogeographic patterns of natives, although the geography of human activities influences the propagule pressure. [source]


    Species richness and parasitism in an assemblage of parasitoids attacking maize stem borers in coastal Kenya

    ECOLOGICAL ENTOMOLOGY, Issue 1 2003
    Guofa Zhou
    Abstract. 1. Parasitoids were reared from four species of lepidopteran stem borer collected in maize in southern coastal Kenya from 1992 to 1999. The stem borers included three native species, Sesamia calamistis Hampson, Busseola fusca Fuller, and Chilo orichalcociliellus (Strand), and one exotic borer, Chilo partellus (Swinhoe). A total of 174 663 caterpillars was collected, of which 12 645 were parasitised. 2. Twenty-six primary parasitoid species were reared from the exotic borer, C. partellus, indicating a rapid accumulation of native parasitoids on the alien borer. 3. The three most abundant parasitoids were the larval parasitoids Cotesia sesamiae Cameron, Cotesia flavipes (Cameron), and the pupal parasitoid Pediobius furvus Gahan. The pupal parasitoid Dentichasmias busseolae Heinrich and the larval parasitoid Goniozus indicus Ashmead were also common. All used an ingress-and-sting method of attack. 4. Cotesia flavipes, introduced into Kenya in 1993, was found in all seasons from 1997 onwards, and has become the most abundant stem borer larval parasitoid in the area. A native congener, Cotesia sesamiae, appeared in all seasons from 1992 to 1999. Together, these two parasitoids accounted for 83.3% of the parasitised borers. 5. Thirty parasitoid species were recovered in Kilifi district, 27 in Kwale, and 15 in Taita Taveta. Parasitism was much greater in Taita Taveta district than in Kilifi or Kwale districts. [source]


    Juvenile growth of two tilapia species in lakes Naivasha and Baringo, Kenya

    ECOLOGY OF FRESHWATER FISH, Issue 3 2008
    J. R. Britton
    Abstract,,, Tilapia species in East African lakes often form the basis of commercial fisheries, with information on their population biology assisting their management. This study utilised otolith microstructure, with validation by modal progression analysis, to provide growth data for two tilapia species in two Kenyan lakes for the first time. Otolith microstructure revealed the growth rate of Oreochromis niloticus baringoensis, a sub-species endemic to Lake Baringo, was fast compared with populations of Oreochromis niloticus; mean daily growth rates were >0.50 mm·d,1 in fish between 12 and 53 mm total length. Growth of Oreochromis leucostictus in Lake Naivasha was also relatively fast when compared with the growth rates of other tilapia species, with mean daily growth rates of approximately 0.35,0.48 mm·d,1 in fish between 10 and 56 mm total length. Growth rates of both species were well described by the Gompertz model and were corroborated by modal progression analysis that revealed similar daily growth rates in modes of young-of-the-year fish.
