Livestock production and poverty alleviation in arid and semi-arid tropical rangelands

  1. 1. Livestock production and poverty alleviation – challenges and opportunities in arid and semi-arid tropical rangeland based systems C. Seré, A. Ayantunde, A. Duncan, A. Freeman, M. Herrero, S. Tarawali and I. Wright
  2. 2. Overview • Rangelands are the largest land use system on Earth. They predominate in arid and semi-arid areas of the World. • Large numbers of poor and vulnerable people live in them. • Arid and semi-arid rangeland systems constrained by low primary productivity, low population densities, lack of market access and infrastructure and high transaction costs. • Population density and climate change creating important changes in land use, access to resources and livelihood strategies of pastoralists. • Arid and semi-arid rangeland systems no longer only livestock enterprises but multiple use systems – e.g. ecosystem services, mitigating climate change, tourism, other diversified livelihood strategies • Research agendas need address trade-offs and synergies from multiple uses pastoral ecosystems to benefit poor people

  5. 5. Drivers of change in pastoral regions • Human Population density: – Can increase competition between rangelands and marginal cropping areas – Increase of cropping and sedentarisation has led to land fragmentation, which in turn decreases grazing ranges and mobility. • Overall, livestock numbers in these region are slowly increasing due to increase demand on livestock products. – However, livestock rate of growth lower than human population growth rate animal numbers per capita decreasing in arid/semi arid areas. • Land tenure and land use changes • Climate change is also a driver, with uncertainty and its impacts will be felt severely years to come.
  6. 6. Consequences of the drivers of change • Transformation of land ownership from common to private property in some pastoral areas • Fragmentation and Sedentarisation of pastoral communities • Land degradation • Market development and evolution
  7. 7. What are various scenarios due to climate change?
  8. 8. Climate change – potential negative impacts • Increased dryness and higher temperatures • Reduction in primary productivity, land use changes, changing animal disease distributions, land degradation • Changes of species composition, livestock productivity, incomes and food security. Climate change will determine a new research agenda for the rangelands of the world

  16. 16. Development challenges For pastoral and agro pastoral systems, the overarching development challenge is to reduce poverty and vulnerability in these regions and also to provide livelihood strategies that provide sustainable pathways out of poverty. • Low population density and low carrying capacity of the ecosystem • How to link poor pastoralists to the national economies? - Mobility presents challenges for transfer of quality information on market prices, However with recent advances in communications technologies (i.e. mobile phones) this constraint is rapidly disappearing. • Systems of low priority for public investment
  17. 17. Linking LGP changes to livelihoods A combination of two systems classifications as a proxy: ● Seré & Steinfeld (1996) livestock classification ● FAO “Farming Systems and Poverty” classification (Dixon & Gulliver, 2001)

  21. 21. Development challenges cont… • Natural resource degradation - Results from ILCA’s long- term monitoring studies in East and West Africa (Ellis, 1992; Hiernaux, 1993) have challenged the assumption that livestock is responsible for rangeland degradation and provided evidence that climate, and not livestock, is the main determinant of changes in the arid/semiarid environments and that the rangelands are resilient and capable of recovery. ILCA studies concluded that, “the strong seasonality of rangeland production in the Sahel limits the risk of overgrazing damaging the environment to short periods and consequently to confined areas.”
  22. 22. Some researchable areas in arid and semi-arid pastoral and agro-pastoral systems
  23. 23. Research area Opportunities for research Spatial • Spatial analysis: Where are the most analysis, vulnerable groups of pastoralists now impact and in the future assessment • Household level analysis: What determines the vulnerability of pastoralists • Trade-off analysis of multiple uses of rangeland ecosystems • Impact assessment and priority setting of integrated rangeland ecosystem uses
  24. 24. Research area Opportunities for research Adaptation Management practices: options to • Rangeland management for multiple climate uses (animal production, payments of variability and ecosystems goods and services) • Rangeland management to mitigate change climate change effects • Strategies for selling and buying animals • Health management practices • Water harvesting techniques • Insurance-based schemes to reduce vulnerability • Early warning systems
  25. 25. Research area Opportunities for research Diversification • Development of practical approaches to of income quantify delivery of environmental services sources by pastoralists and markets for such services • Exploitation of niche markets for livestock products with certain characteristics • Development of biofuel crops for ASALS • Mechanisms for promoting increased revenues for communities from wildlife conservation and tourism • Off farm income, remittances and/or exiting from pastoralism
  26. 26. Research area Opportunities for research Increased • Collective action mechanisms for market access selling animal and other products • Novel methods of networking and sharing benefits of ecosystems • Increased information and communication on marketing options • Identification of new market options (specialization and diversification)
  27. 27. Conclusions • Beyond traditional research paradigms for the rangelands have been largely about increasing the primary productivity of the land. • The new role this ecosystem can play requires a different more holistic research paradigm. (economic, social, ecological) of a diverse set of options for different members of society. • New collective action mechanisms • Rangeland systems will diversify but will also require a degree of specialisation of their livestock systems. increased integration of the pastoral economy with other regions. • Pastoralism is no longer seen as a tragedy for common grazing areas but rather as having the potential as a viable part of complex livelihood strategies. • Participation in C- Markets
