Pastoral livestock farming: what productive practices are needed to preserve biodiversity?

 

Pastoral livestock farming is booming due to the growing global demand for animal products. In addition to the production of meat, milk and hides, pastoralism provides numerous other social (employment), economic (savings) and environmental (manure, energy, etc.) services.

Pastoralism is an extensive production system in which livestock are fed mainly from natural pastures. It is thus distinguished from fixed or sedentary livestock farming by the mobility of the herds. All BIODEV2030 countries have identified agriculture as a priority economic sector contributing to biodiversity erosion and national development. 2 in particular have selected pastoral livestock farming:Ethiopia and Kenya.

 

STAKEHOLDERS & ECONOMIC CHALLENGES Pastoral livestock :

Pastoralism is an ancestral activity. In recent decades, the demand for animal products has risen sharply. Indeed, it is an essential source of economic activity in arid zones where other forms of agriculture are impossible.

Pastoral livestock products are therefore an important source of household income. They make a significant contribution to national GDP. For example, pastoralism accounts for 19% and 13% of GDP in Ethiopia and Kenya respectively1.

Pastoralists produce much of Africa's meat and milk. However, they face enormous difficulties in selling these products. All players in the pastoral livestock value chain (producers, traders, processors, financial institutions, government) therefore have a common interest in working together to improve production practices and increase outlets.

the impact of pastoral livestock farming on biodiversity :

Pastoral livestock farming nevertheless exerts numerous pressures on ecosystems. Herd mobility, increasing numbers of animals and poor management of plant resources contribute to the main mechanisms responsible for the erosion of biodiversity in Sahelian regions: habitat modification, overexploitation of resources, pollution and biological invasions.

Demographic growth and agricultural expansion have led to the densification of livestock activities on an increasingly reduced pastoral area. Overgrazing, exacerbated by the increase in livestock numbers, is contributing to desertification. Habitat modification (soil degradation, depletion of vegetation, introduction of plant species for grazing) impoverishes the living environment. It also encourages the invasion of invasive species, whose spread is facilitated by the movement of livestock and the use of bush fires. Excessive pressure on the environment maintains a vicious circle that can be exacerbated by climatic hazards.

Pastoral livestock farming has a negative impact on biodiversity due to :

1. Overgrazing: impoverishment of the environment, leading to desertification. Livestock movement should not be guided solely by the availability of resources. Their renewal and the carrying capacity of the environment must also be taken into account.

2. Fewer pastures: leading to increased competition for available forage with wild species and livestock grazing in protected areas.

3. Pastoral practices: veterinary treatment, bush fires and the cultivation of fodder for livestock lead to pollution and biological invasions. These practices must be controlled and reduced.

COMMITMENT TRACKS :

  • Facilitate seasonal herd mobility to adapt to seasonal and inter-annual variations in pastoral resources (water and forage). To avoid intense grazing during the growing season and heavy loads of sedentary herds.
  • Develop new concerted approaches to wildlife management. Involve pastoral communities in wildlife conservation in pastoral areas and around protected areas.
  • Involve pastoralists and local stakeholders in the participatory restoration of degraded Sahelian ecosystems (particularly the woody stratum).
  • Promoting forage crops adapted to dry areas
  • Reduce agricultural and mining pressure on grazing lands
  • Ban bush fires
  • Reduce the risk of overgrazing by setting conditions for the use of rangelands and watering holes:
    • Ensuring the widest possible access for livestock to rangelands and watering points: concerted community management of rangelands, including post-cultivation stubble.
    • Concerted investment in hydraulic, rangeland management (passage corridors, pastoral lodges and reserves), veterinary and commercial infrastructures.
