10(2): 665–687. In 2010, there are again significant differences between group ranches regarding migration behaviour (Ilmotiok vs. Tiamamut; chi2 = 15.023, p < 0.020). Herds rarely if ever fragment during grazing bouts, so a single animal’s behaviour was assumed to be representative of the overall herd’s behaviour and location. Conditions appear to be drying out over time; this is evident particularly in later part of the twentieth century, where rainfall levels start to show a downward trend. Herders in Ilmotiok do not cite using any other outside patches during this year; however, they do cite moving stock to affines or relatives in other neighbourhoods in their own group ranch to acquire grazing access (Lorubay or Naserian). Exploiting heterogeneity: Habitat use by cattle in dryland Zimbabwe. There is a statistically significant correlation between NDVI and rainfall (at a lag of one month) indicating an improvement in forage availability during this time frame (R We suggest that dual access to private transportation and reliable, timely information via cell phone (both a result of greater access to cash) is the major difference between these two classes. In many parts of East Africa, pastoral families must compete with endangered species conservation and eco-tourism (Gadd 2005; Muthiani et al. In essence, our model extends traditional frameworks of pastoral livelihoods to include a new set of dynamic pastoral actors who are fully integrated into a cash market. Wambuguh, O. Pastoralism 6: 16. Lastly, no proper evaluation of wealth strata or wealth inequality has been carried out in Mukugodo since Herren used informant wealth ranking to stratify households in 1986. DR assisted with model development, research methods, and editing of the manuscript. Herders make decisions about where to migrate with their livestock based on a variety of social and ecological factors. Nairobi: ILCA. The emergence of globalized markets and the integration of globalized production in developing countries has forced many pastoralists, as well as the rest of the world’s consumers, to shift their economic strategies of production to accommodate continuously evolving markets. Quadratic fit of maximum distance travelled as a function of maximal distance to water by wealth rank. D.I.R. Factors facilitating changes in absolute number of livestock among different social strata. This dynamic wealth ranking system is explained in greater detail in the ‘Methods’ section of this paper. Decisions about when to move are made communally. Sellen, D.W. 1999. The authors declare that they have no competing interests. Total actual milk yields available per capita for all four years of the current study (n = 31 families). These yearly values are then used to analyse relationships between wealth and herding strategies in our population. Dietz, T., A.A. Nunow, A.W. In this paper, we will characterize (i) the environmental conditions across both space and time of Ilmotiok and Tiamamut group ranches in Mukugodo Division, Laikipia, Kenya; (ii) mobility and local/regional range use patterns by group ranch and wealth class; and (iii) the influence of wealth differences on herding and production strategies that families use to cope with environmental variation or stress. On the other hand, rich households were more dependent on commercial livestock transactions than wages for capital; tended to lose fewer total animals during drought; had access to external sources of labour, such as hired herders; and migrated with their herds to new areas when conditions were bad. as well as by wealth rank (rich vs. poor; p < 0.001). …the beginnings of recorded history, pastoral nomadism, practiced on a grandiose scale, was the economic basis of the great Central Asian empires. Global nutrition dynamics: The world is shifting rapidly toward a diet linked with noncommunicable diseases. We hypothesize that herders should migrate to distant grazing patches when local forage and water conditions decline, such as during droughts or dry seasons. Huysentruyt, M., C.B. Kaye-Zweibel EW .2011. 1987. Wealth differences in grazing access exist at home as well. CAS Private ranches usually charge a grass rental fee to herders from off property. Journal of Arid Environments 74: 403–413. Bond partners reciprocate requests indefinitely, usually in the form of livestock, although in Mukugodo, virtually any good or service can serve as an osutua gift (Cronk 2007, p. 353), even cash. 2007. 2006; McCabe 1987). The staff, researchers, and local community at Mpala Research Center were extremely helpful and supportive during the data collection portion of this study. 2010. Stockholm: Dept of Social Anthropology, University of Stockholm. This indicates that there may be other factors, such as what type of herd an individual owns (cattle, sheep, or goats or a mixture of the three), their ability to acquire free labour to migrate to a squatter parcel rather than using rented labour, and access to private parcels of land that my be unavailable to other herds, which reduces competition for resources with other herders on crowded grazing lands. 6, 2nd edition, edited by Jay Innsbruck and Erick D. Anger, 37-38. Cattle dynamics in African grazing systems under variable climates. Godoy, R., V. Reyes-García, T. Huanca, W.R. Leonard, R.G. 1989. Find out what a pastoral society is, and the ways of those who live the pastoral lifestyle. Ethical approval was granted under Institutional Review Board for the Ethical Treatment of Human Subjects at Princeton University (Protocol # 4051). We labelled these weighting factors as A1, A2, and A3 in our mathematical expression of wealth. First of all, the number of locations that herders report migrating to with their livestock is significantly reduced from 2009 to 2010 (23 vs. 7, respectively). In a pre-industrial society, food production, which is carried out through the use of human and animal labor, is the main economic activity. Human Ecology 20: 383–405. Grazing on Mpala, however, is only open to those renting grazing for cattle, so goat and sheep herds are generally not allowed in, except under extreme duress. Hatched lines indicate hypothesized linkages. A note on the statistical significance of changes in inequality. Ryan Z. In the 1960s, droughts were strongly episodic, with one drought occurring every four years (1961, 1965, 1969). 1988a. The impact of wealth on smallstock production and utilization in a pastoral system: Mukugodo Division, Laikipia District, Kenya. Dar es Salaam: Mkuki na Nyota. 2011; Omosa 2005). 2 = 0.40, t (11,311) = 85.9, p The flocks of domestic animals not only provide them with subsistence. Risky livestock markets and unfavourable terms of trade may deter pastoral families from engaging in livestock transactions, reducing their ability to acquire cash to feed their families and save for the future. NDVI is an index that parameterizes the contrast between PAR absorption and NIR reflectance as a gauge of plant productivity (Verbyla 1995). Nairobi: University of Nairobi, Institute for Development Studies. It measures the degree of inequality in a frequency distribution of values, such as income. Lastly, this study allows us to evaluate the dynamics of variation in new forms of herd management, particularly modified mobility patterns and shifts in herd structures. We extracted these data from the GLEWS dataset mentioned in the previous section. 467. 1987. Tiamamut herders report migration to other areas in 2008, such as Endana (12.5%), Fois (6.25%), and Koija (6.25%). Reasserting the commons: Pastoral contestations of private and state lands in East Africa. It has declined as a practice because of increasingly erratic rainfall, dried out and dying grasslands, rapid population growth, and restrictions on household and herd mobility, such as sedenterisation or privatization of land. If wives were surveyed on livestock transactions when husbands were absent, they often did not know the value of the livestock sold by their husbands or were not told the value of the transaction. The answers from these surveys were then converted into binary (0,1), ordinal, and continuous data for analysis. who is moving to where, for what reasons and for how long, and whether there is a short- or long-term mobility pattern. 1988b. In effect, ranches like Mpala provide herders with subsidized grass and labour for cattle during dry seasons and droughts. During this period, herd sizes and milk yields decreased precipitously for all classes in both group ranches. Individual and collective rationality in pastoral production: Evidence from Northern Kenya. “Foraging.” Behavioral Sciences Department, Palomar College. Ecological and social characterization of key resource areas in Kenyan rangelands. Roba, F. Zaal, M. Salih, A. Ghaffar, and M. Ahmed. Some absentee lands offer safe squatting grounds near other patches, such as Mathira 2 being a holding ground for Segera and Karashira as a holding ground for the Rumuruti approach to the Aberdare Mountains near Mifugo. Cultural Anthropology, 7th edition. The data we present here seek to investigate these potentially distinct patterns of recovery via an evaluation of environmental features, herding behaviour, herd management, drought responses, and mobility patterns. As such, herd owners do not typically sell female animals under any circumstance. In this region, animals are raised for the production of milk not meat. New York: McGraw-Hill, 2014. Deep convexity in the overall distribution of incomes in our population indicates that incomes and assets are highly unequal, with three to four families controlling approximately 50% of the wealth (see Figure 13). Fratkin, E., and E.A. Most pastoralists are monotheistic (but not all of them); usually the belief is tied closely to their animals. Secondly, there has been rapid market integration in this particular region of Kenya since the 1980s (Gertel and LeHeron 2011; Herren 1989; Huysentruyt et al. Our framework thus identifies activities and linkages that illustrate the process These factors make it necessary to call for alternative lines of questioning and hypothesis generation about pastoralism and pastoralist’s lives, particularly as we explore current livelihood practices and pastoral economics in our highly globalized world. Pastoralism is characterized by extensive land use. Article The Ariaal split the herd and pasture them in different places, a practice that ensures herd survivability against disease and drought. This technique quantitatively maps changes in herd composition and distribution for study households within each of the group ranches. Mid- to late-Holocene vegetation dynamics on the Laikipia Plateau, Kenya. Development aid and community public goods provision: A study of pastoralist communities in Kenya. Wealth and pastoral dairy production: A case study from Maasailand. When the results in figures 19 and 20 are converted to a common currency of TLUs as described in the Methods section, wealthy herders who enter the drought with higher TLUs (for rich, M = 80.56, SE +/- 8.72; for poor, M = 18.57, SE +/- 5.41; t (16) = 6.035, p < 0.0001, N = 17) then poor families, in fact do lose significantly more TLUs then poorer families (for rich, M = 54.17, SE +/- 7.33; for poor M = 10.62, SE +/- 4.54; t (16) = 5.05, p < 0.0001, N = 17). We chose to sample herds based on neighbourhoods: one large neighbourhood in Tiamamut and two smaller ones in Ilmotiok. Worldwide values of Gini coefficients range from highly equal (Slovenia; 0.24) to highly unequal (South Africa; 0.70). Production is for more than meat and milk. We hypothesize that differences in herding strategy and herd management, such as herd size, composition, and structure, will influence household production potential of milk. In 2011, the curve starts to return to 2008 levels but is actually less convex than 2008 on the upper half of the curve. In a pastoral groups economy as being the most influential factors determining migration. Roads are only accessible during daytime hours, so herders requiring nighttime transit through private ranches must negotiate those access rights in advance (Mike Littlewood, personal communication, 2011). Very fortunately, I seldom have to worry about where my food comes from. Public roadways from communal lands through private lands provide access to public lands where pastoral families set up temporary camps for grazing during dry seasons (Hauck, personal observation, 2008 to 2011). Furthermore, the requirements set by the Institutional Review Board on the treatment of ethical subjects requires researchers to exclude any data from subjects who do not give their permission to participate in a particular assessment, measurement, or questionnaire. Wealth, in modern times, translates into access to cash and the products of globalization and, most importantly, an increasingly diversified diet. poverty, generating economic growth, maintaining biodiversity, managing the environment and building resilience to climate change. The study was designed as a mixed longitudinal cohort study (Goldstein 1968) of socio-economic subsistence practices, diet, and health. The results of these two indices agree with our overall visual interpretation of the Lorenz curves (Figure 13). Nomadism was the centre of their economy prior to Russian colonization at the turn of. The exchange of cattle as part of a marriage helps to maintain herd diversity and distribute the wealth among the people. These diverse approaches are not mutually exclusive but complementary. 2011; Muthiani et al. This limits poorer households, whose herd sizes are much smaller anyway, to reduced herd growth, lower market value, and decreased terms of trade in the market. The Ewaso Nyiro River also creates an impassable boundary during wet periods (or when the flower farms downstream unload their dirty water onto pastoralists upstream), making the Ilmotiok group ranch in particular an island for part of the year. Journal of Arid Environments 29: 221–237. Pastoralism is a subsistence strategy dependent on the herding of animals, particularly sheep, goats and cattle, although there are pastoralists who herd reindeer, horses, yak, camel, and llamas. BurnSilver, M.M. Boston: Pearson Education, Inc., 2007. The overall model was statistically significant, explaining approximately 80% of the variation we observe in large stock milk yields (R University of Edinburgh. The herding radius is defined as the single furthest distance travelled by the herd from the homestead (often this point is the water source). He is the Director of African Studies at Princeton University. 2011. Journal of Arid Environments 72: 820–835. However, given its close proximity to Mpala (which provides security patrols near the borders and nearby dams), many herders choose to move there, presumably because it is safer and closer to home than more distant patches that may have better quality grazing. Google Scholar. Dietz. Therefore, we estimate their value to be twice that of a single cow (1.4/head). New York: CRC Press. An age set is a group of individuals of roughly the same age that are given specific duties within the society at large. 2011). Similarly, by plotting a different curve for each year, we can establish that wealth inequality contracts during poor rainfall years and expands during the first year following a drought. In short, pastoralists cannot escape the market as their new arena of social and monetary exchange, nor can they transcend their traditional life ways or fully return to them. Thus, forage levels increase dramatically within a lag of about one month following a major rainfall event. Monthly rainfall and NDVI values for the Ilmotiok group ranch over a five-year period (2007 to 2012). It is the quantifiable outcomes of these different approaches to modern livelihood challenges that allow us to evaluate the impact of new economic opportunities on human health and well-being for pastoral families now and in the future. Tiamamut herders report using three different patches during this year equally: 33% to Kere Farm, 33% to Muhammad Farm, and 33% to Sukuton. Having herds: Pastoral herd growth and household economy. Herders from Tiamamut that moved their stock to Kiperen, Mpala, and Segera acted in accordance with our predictions. Similarly, 37% of both Ilmotiok and Tiamamut herders migrated to Sukuton in 2008. Deaton, A. Our 2008 curve is assumed to be the quasi-‘normal’ distribution of incomes during normal years of rainfall and forage accumulation. However, in extreme cases (at Mpala only), a few herders may be able to negotiate access for sheep herds who are highly dependent on grass. Human Ecology 35: 709–721. Our framework makes a few assumptions about the current Kenyan pastoral system. To obtain accurate data on movement, we affixed GPS collars (Savannah Tracking Ltd, 2012) on a single adult animal from each herd. In this paper, we evaluate how differential access to local resource distribution (grazing patches) affects production via herding and whether differences in wealth statistically interact with other main effects to shape household decisions and outcomes. Having their own transportation gives them an advantage over herders dependent on local information; timely access to better information about patch quality allows them to make more informed decisions about where to migrate or when. Galaty, J.G. 2011; Cronk 1991; Cronk 2007; Herren 1987). Annual rainfall valuesFootnote 7 for the Ilmotiok and Tiamamut group ranches indicate that 2007 and 2008 were relatively dry years. On the northern side of the Division, there is a livestock holding ground, which is now settled by Samburu pastoralists, and a second livestock holding ground in the southwest, which is now privately owned (Dan Rubenstein, personal communication, 2012). Large stock milk yields decreased sharply in 2009 and 2010 (p < 0.001), with year being a statistically significant predictor of decreases in milk yield. Each herd was monitored with a GPS collar for an average of four consecutive days. Pastoralism Muthiani, E., J. Njoka, P. Kinyua, and G. Gitau. TLU, as a standardized measure, is usually a good indication of a family’s access to cash and whether that cash is accessible in small (shoats) or large (cattle, camels) packets of wealth. In fact, over the entire study duration, we only recorded six livestock gifts, two of which were from a poor family to a rich family who had assisted them during the drought.
