Efficacy of Integrating Herder Knowledge and Ecological Methods for Monitoring Rangeland Degradation in Northern Kenya

Abstract

The world-wide debate on land degradation in arid lands, usually linked to local land use practices, does not reflect methodological advancements in terms of assessments and monitoring that integrate local communities’ knowledge with ecological methods. In this paper, we evaluated the efficacy of three different methods related to herder assessments and monitoring of land degradation; herder knowledge and ecological methods of assessing impacts of livestock grazing along gradients of land use from settlement and joint monitoring of selected marked transects to understand long-term vegetation changes in southwestern Marsabit northern Kenya. The performance of each method was carefully evaluated and interpreted in terms of the indicators used by herders and ecologists. Herder interpretations were then related to ecologists’ empirical analysis of land degradation. The Rendille nomads have a complex understanding of land degradation which combines environmental and livestock productivity indicators, compared to conventional scientific approaches that use plant-based indicators alone. According to the herders, the grazing preference of various livestock species (e.g., grazers versus browsers) influences perceptions of land degradation, suggesting degradation is a relative term. The herders distinguished short-term changes in vegetation cover from long-term changes associated with over-exploitation. They attributed current environmental degradation around pastoral camps, which shift land use between the alternating wet and dry seasons, to year-round grazing. We deduced from long-term observation that herders interpret vegetation changes in terms of rainfall variability, utilitarian values and intensification of land use. Long-term empirical data (23 years) from repeated sampling corroborated herder interpretations. Land degradation was mostly expressed in terms of declines in woody plant species, while spatial and temporal dynamics of herbaceous species reflected the effects of seasonality. The efficacy of the three methods were inferred using explanatory strengths of ecological theory; insightfulness of the methods for describing land degradation and the likelihood of using the methods for promoting local community participation in the implementation of the UN Convention on Combating Desertification (CCD) and the Convention on Biological Diversity (CBD).

Notes

  1. All the grazing landscapes have comparable elevations at <500m a.s.l.

  2. Among the field team, two of the research assistants were involved in the earlier surveys. The assistants were responsible for sampling during the dry season in 2005 and the wet season in 2006.

  3. Voucher samples of the plant species unidentifiable in the field were deposited at the Herbarium of the KARI station in Marsabit.

  4. The terms ‘decreasing’ (used by the herders) and ‘declining’ (used by ecologists) are interchangeable. In both cases, the reference was made to the past benchmark conditions referring to historical knowledge for the herders, and for the ecologists to the IPAL surveys of 1982 in the wet season and 1983 in the dry season.

  5. The after-birth organ is sticky and could collect litter when dropped by livestock at birth. The symbolism for land degradation is that even plant litter cannot be found.

  6. Herders usually use the concept of an animal’s comfort in lying down, as they become restless where the conditions are not suitable. The inference is always made in terms of the conditions of the soils (see Roba and Oba 2008).

  7. Ecologists describe land degradation in terms of soil movements and loss of soil nutients (see Oba et al. 2008c).

  8. The Rendille were blamed for over-exploitation of woody plants. For this reason, the herders did not offer opinions, perhaps reasoning that ‘outsiders’ do not appreciate their use of trees for building fences for protecting their livestock from predation by ‘hyenas.’ The herders used ‘hyenas’ as a generic term for all large predators that kill their livestock. When questioned about their use of trees around pastoral camps, an elder responded “...then would you pay for our goats, [which are eaten by hyenas] if we stopped cutting trees...We have no solution ourselves...”
