Analysis of good practice

This is a practice that is promoted by the Forestry Commission, Ministry of Food and Agriculture, Environmental Protection Agency, Food and Agriculture Organization and other NGOs into forestry and greening Ghana. This is a conservation of water, soil and biodiversity practice because it controls erosion on gullied land, road embankments and replenishing construction sites, mine spoils and areas cleared by patch cutting. Thus it rehabilitates degraded lands. The other merits in favour of this practice are that it provides cover, recycles nutrients, adds organic matter to the soil and improves soil structure. Damage to soils and other natural resources through mining, construction, overgrazing and bad farming practices and natural aridity of lands causing soil infertility, poor soil nutrients and moisture underscore the adoption and implementation of this practice. The practice has the effects of adding organic matter to the soil through litter fall, recycling nutrients, improving soil fertility and controlling soil erosion. It also rehabilitates degraded and marginal lands, creates sustainable environment for soil microbial activity, enhances infiltration and conserves soil moisture and provides quick method of obtaining ground water.

All agro-ecological zones in Ghana


9

Objectives of the good practice in connection with the Sustainable land management (GDT), the naturel resource (RN) and the CC

  • Reduces erosion by increasing soil cover

  • Increases soil organic matter, soil structure stability water holding capacity and improves soil fertility

  • Recovery of native vegetation and species

  • Protects the environment against extremes of climate elements (rainfall, temperature and windstorm)

10

Description of human’s environment /gender (nature of famers practicing GP)

12

Type of utilization lands in connection with the Good Practice (cultivated fields, pasturage, forests, mixed…)

Cultivated fields, pasture and forests


13

Description of GP

  • About the integration of trees/shrubs and sometimes animal husbandry in the farming system

  • It combines annual crops with herbaceous perennials or trees on the same unit

14

Type of land degradation problems or of RN (natural resource), which GP addresses

  • Poor vegetation cover and nutrients

  • Arid lands

  • Eroded soils

17

Manner in which GP fights land degradation

  • Reduces erosion by increasing soil cover

  • Acts as runoff barriers by means of closely planted hedgerows

  • Increases soil organic matter, holding capacity and fertility

  • Sequesters carbon above ground and in soil

  • Replenishes vegetation cover, biodiversity corridors as well as climate mitigation

18

Level of technical knowledge required to implement GP

Knowledge in

  • Tree planting

  • Animal husbandry

  • Agronomic practices

19

20

Practical pieces of advice of implementation

  • Balance trees and crops to minimize the tendency of water and nutrients competition.

  • Compatibility of crops in terms of morphology, rooting system is necessary

  • Intensification of animal rearing is important to reduce conflicts of grazing

  • Proper and favourable land tenure system to support tree planting and increase adoption

21

Advantages / effects / impacts

  • Increased earnings, soil improvement, release pressure on forests lands for fuelwood, fodder and arable cropping and protection of the environment

  • Links erosion control practices with production and thus helps to make these practices an integral and permanent part of the farming system

22

Constraints to the implementation of GP

  • Water and nutrients competition between trees and crops leading to reduced crop yields

  • Tree component reduces land for arable crops

  • Grazing creates conflict

  • High initial labour cost

  • Land tenure issues may adversely affect tree planting thereby limiting adoption

23

Measures necessary for lifting constraints

  • Adequate water supply for trees and crops

  • Acquire large tracts of land or manage tree-crop ratio

  • Intensification of animal rearing

  • Encourage communal/group work to reduce cost of labour

  • Favourable land tenure system to ensure farmers’ investment security

24

Cost of achievement

  • Labour GHS 2000/ha

  • Other inputs GHS 3000/ha

  • Land GHS 4000/ha

25

Scale in the dissemination process and sustainability (1= initial, 2= maturity ; 3 = lethargy)

Initial


26

Recommendations for the dissemination of GP

  • Extension services and training

  • Group/associations/clubs

  • Documentaries in the media
