GLOBAL ENVIRONMENTAL CHANGE AND FOOD PROVISION IN SOUTHERN AFRICA

1
GLOBAL ENVIRONMENTAL CHANGE AND FOOD PROVISION
IN SOUTHERN AFRICA

• Explorations for a possible GECAFS research
  project in southern Africa
• Team members Martin Muchero, Pauline Dube and
  Jaap Arntzen

2
GECAFS Research questions

•  How might the projected climate change stresses
  further affect the food systems of Southern
  Africa who and which place will be most
  vulnerable to these changes?
• What are the other key determinants of short and
  long-term food provision that needs to be
  addressed simultaneously with GEC?
• What measures can be put in place to minimise
  impacts of GEC and or take advantage of positive
  trends that may arise from these changes?
• What is likely to be the short and long-term
  feedback from measures adopted specifically to
  avert negative impacts or take advantage of
  changes in climate patterns?

3
Work programme

• Identify potential stakeholders and data sources
• Solicit research needs from policy makers and
  scientists in southern Africa
• Outline key research issues for potential GECAFS
  Southern Africa project

4
Methods used

• Interviews
• Literature review
• Review of statistics
• Review of info on GEC and southern Africa

5
Report structure

• Classification of food systems and trends in food
  provision
• Main socioeconomic and physical features of
  southern Africa
• Main regional policy and research initiatives
• Identification of research topics for three
  GECAFS themes

6
Food resources and provision

• Food provision is about ensuring that people take
  in sufficient variety of substances to maintain
  life and growth.
• Range of food resources, including cereals and
  other conventionally cultivated crops,
  vegetables, fruits and edible oils, Meat, milk
  and dairy products, fishery products and other
  (non-conventional) products collected from the
  natural environment or cultivated.

7
Food systems

• Food production systems determined by
• Type of food produced
• Method of production
• Production strategy
• Classification see table 1.
• Food availability determined by production,
  transport, distribution and storage capacity
• Food accessibility determined by availability and
  income generation, distribution and pricing.

8
Regional trends in food provision

• Declining p. c. food production
• Under-utilisation of agricultural land resources
• Small size of irrigated food production
• Declining p.c. food consumption
• Maize is most important cereal. Sorghum and
  millet confined to driest areas.
• Difference between comparative advantage for
  crops and actual crops grown
• Government support has stimulated maize
  production

9
Food trends continued

• Livestock production mostly in South Africa,
  Tanzania and countries such as Botswana and
  Namibia
• Sufficient grain storage capacity for regional
  production
• Transport and communication networks are poor

10
GEC and food production in southern Africa

• Changes in production potential of maize and
  certain trees.
• Negative and positive impacts on food production
  and provision (south -- north )
• Lower rangeland productivity in southern parts
• A decrease in rangeland quality in southern
  Africa
• Changes in water cycle and availability in
  combination with growing water competition
• Growing poverty in affected areas, restricting
  adaptive capacity

11
Development-environment challenges

• Reducing poverty and hunger
• Accelerate economic and agricultural growth
• Increased access to drinking water and
  sanitation
• Political and economic stability
• Regional integration and specialisation
• Improved natural resource management
• More productive use of natural resources
• Regional specialisation based on comparative
  natural advantages
• Water scarcity
• International-regional commitments

12
GECAFS challenge in southern Africa

• Southern Africa is unique for GECAFS as food
  insecurity is a growing problem in southern
  Africa, and for many countries within the region.
  
• Existing regional efforts on food provision are
  mostly short-term oriented, aiming to revive
  agricultural growth and development.

13
Research issues for theme 1

• Integrating long-term GEC concerns and impacts in
  the short-term struggle to improve food provision
• Detailed assessment of GEC on the major food
  products and transport and distribution systems
• Establishing an inventory of traditional
  knowledge on past GEC and vulnerabilities
  experienced then
• Vulnerability assessment (areas, groups,
  products)
• Shifts in production belts of crops and animals
• Potential for new income-generating products
• Changes in water availability and requirements
• Identification of areas with enhanced and reduced
  food production potential and linking these
  systems

14
Research issues for theme 2

• Identify and evaluate the possible adaptations
  mechanisms
• Identify and learn from past and current coping
  mechanisms employed by vulnerable groups in their
  day-to-day food supply systems
• Analyse and strengthen the capability of
  communities and countries to adapt as much as
  possible
• Identify the most suitable level at which each
  adaptation should be carried out.

15
Research issues theme 2 continued

• Data generation and dissemination
• Monitoring and early warning systems (climate,
  local production, regional and global markets)
• Focused information on adaptation options
  available including research on alternative crops
  or livestock species
• Vulnerability assessments (areas, groups)
• Dissemination of information-data
• Wide range of agricultural and non-agricultural
  adaptations
• .

16
Research issues theme 3

• Possible environmental impacts of adaptations
  include
• Changes in biodiversity due to GMO and extending
  the agricultural frontier
• Agricultural pollution associated with use of
  fertiliser and pesticides
• Water logging and salination due to irrigation
• Land degradation due to agricultural pressure and
  use of less suitable land
• Increase water scarcity due to irrigation.

17
Research issues Theme 3 continued

• Development impacts include
• Extra costs of agricultural production due to GEC
• Changes in consumer patterns and loss of economic
  access for those engaged in food
  production/processing
• Extra costs of food imports
• Mobilisation of international funds for
  mitigation/ adaptation measures
• Future of food aid
• Over-exploitation of resources
• Intense competition for resources in favoured
  regions in response to developed intra-regional
  trade

18
Proposed GECAFS projects in southern Africa

• Three interlinked projects
• Project 1 in southwest/central part of southern
  Africa where production potential is adversely
  affected by GEC.
• Research issues
• GEC impact on food production and livelihoods
• Adaptation mechanisms and their impacts
• Project 2 located in north-western parts with an
  enhanced production potential
• Research issues
• Expected positive impact on food production
• Shifts in crop and animal production belts

19
Proposed GECAFS projects in southern Africa

• The projects would be linked by transport, trade
  and policy issues, including regional integration
  and specialisation (project 3).
• Project 3 Regional agricultural trade
• Location region-wide (SADC)
• Research issues
• Regional transport and food distribution networks
• Regional food security and reserves
• Policies and governance
• Regional specialisation, integration and trade
