Zone Description CC Impact Forecast Adaptation Strategies
Zambezi West Bank A poor and very hot zone, sparsely populated and with poor road network. It is connected to the country by pontoons on the Zambezi River and in times of high rainfall it is inaccessible. Main crops are cassava, maize and sweet potatoes. Livestock kept include cattle, goats and poultry. Unskilled casual labour and petty trade are the main income sources. a.Increased incidence of floods
b. Lack of draught power and loss of income due to livestock death
c. Cattle diseases
d. Decrease in crop yields due to drought and shifts in agricultural seasons.
e. Increase in water borne diseases
a.Timely vaccination of livestock and switch to more resilient livestock. b.Settle communities in flood free areas.
c. Construction of small dykes to protect agricultural blocks from floods. d.Expand water harvesting & storage techniques & encourage irrigation farming
The Kuzungula-Mwandi Plain A poor and very hot zone (semi-arid) with periodic drought and flooding. Maize, cassava and cattle production are the major economic activities. Cross border trading is a major source of income as it borders with four countries, Angola, Zimbabwe, Namibia and Botswana. Other sources of income are crop and timber production, curios and seasonal wages from commercial farms. a.Decrease in crop productivity due to low rainfall and shifts in agricultural seasons.
b. Spread of pests and pathogens which favour high temperatures
c. Decrease in the availability clean water and for agriculture.
d. Increased incidence of floods as the incidence of heavy rainfall events increases.
e. Loss of wages due to little or no activity in commercial farms and reduced income to continue with cross border trade.
a.Increase land under irrigation b.Expanded rainwater harvesting, water storage & conservation techniques, water reuse and irrigation efficiency.
c. Switch to more resilient livestock production systems and crops. d.Improved land management, such as erosion control.
Zambezi Floodplain A middle zone on a low-lying wetland that floods excessively yearly. The floods destroy crops and infrastructure. Major grown crops are maize, rice and sorghum. Main livestock are cattle and pigs. Pigs are kept mainly for sale. The area is dissected by the Zambezi River, offering opportunities for fishing and water transport. There is the potential to produce two crops of maize per year. a.Increased incidence of floods as the incidence of heavy rainfall events increases.
b. Increased risk of water pollution & decreased water quality due to erosion resulting in water borne diseases.
c. Increased prevalence of livestock disease due to increasing temperatures.
e.Settle communities in flood free areas.
a. Construction of small dykes to protect agricultural blocks.
b. Expand soil, water and nutrient conservation practices.
c. Increase land under irrigation to boost crop production.
Mulobezi Woodlands A poor and dry zone under infertile soils. Sparsely populated. Livelihoods are subsistence oriented. Poor road network limit access to markets. The huge forests provide timber which is a source of income. Saw mill industries and a rail line are as a result of the huge forests. The industries provide labour. Maize is the major crop grown and livestock are cattle & goats. a.Extinction of some tree species due CC b.Increased soil erosion due to over exploitation of forests
c. Reduced crop yield due to erratic rainfall patterns and shifts in seasons.
d. Spread of diseases due to increasing temperatures
e. Reduced in water availability
f. Frequency of veld fires may increase due to increasing temperatures
a.Introduce alternative forms of silviculture
b. Introduce soil, water and nutrient conservation practices
c. Expand rain water harvesting and water storage
d. Increase land under irrigation and exploitation of groundwater
Sioma Plain A poor agricultural zone that produces maize, rice and cassava in its wetlands which also support fishing. Cattle rearing is practiced. The huge forests support timber industry. Soils are rich in wetlands but poor in uplands. Annual rainfall is between 800 to 1000 mm. Crops, livestock and timber sales are the sources of income. Road infrastructure is poor, limiting access to markets. a.The prevalence of cattle disease and death causes lack of draught power and loss of income b.Soils in the upland are infertile, producing a limited number of crops.
c. Prolonged dry periods causing shifts in agricultural season
d. Extinction of some tree species due to increasing temperatures
a.Introduce other crops suitable for the infertile upland and increase land under cassava.
b. Settle communities in flood free areas.
c. Expand water harvesting & encourage irrigation farming in the upland
d. Introduce alternative forms of silviculture
e. Timely vaccination of livestock and switch to more resilient livestock
Zambezi East A poor and sparsely populated dry zone. Poor road network. Huge forests for timber. Main crops are cassava, maize, and sweet potatoes. Main livestock kept are goats, cattle and poultry. Unskilled casual labour and petty trade are the main income sources. Also cross border trading provides income as it borders with Angola. The zone has better and well developed social and economic infrastructure. a.Extinction of some tree species due to changing climate
b. Increased soil erosion due to over exploitation of forests
c. Reduced crop yield due to erratic rainfall patterns and shifts in seasons.
d. Spread of diseases due to increasing temperatures
e. Decrease in water availability due to drought and evaporation
f. Frequency of veld fires may increase due to increasing temperatures
a.Timely vaccination of livestock and switch to more resilient livestock. . b.Introduce alternative forms of silviculture
c. Introduce soil, water and nutrient conservation practices
d. Expand water harvesting & storage techniques & encourage irrigation farming
