Land Degradation and Economic Activities: Linkages and Impacts in the Talensi-Nabdam District (TND),
Ghana
Outline of presentation Introduction Problem in context Theoretical basis of study Research methods Results and Discussions Conclusion Recommendations References
IntroductionSound and sustainable environmental
management is a great challenge in this 21st century (Gausset and Whyte, 2005).
Land degradation is variedly understood (Eswaran et al., 2001; Adams, 2009).
Conventionally, argued as “decline in productivity of land” (Scherr and Yadav, 1996; Abass, 2007; UNEP, 2007).
Introduction cont’dLand degradation has affected
economic activities worldwide (Global Environment Facility, 2003).
Human economic activities are also argued to have caused decline in land quality (Eswaran et al., 2001).
We explore this complex interrelationship between land degradation and economic activities in the Talensi-Nabdam District.
Problem statement Land degradation is a social, economic and
environmental problem in TND (Adams, 2009).
It is a real challenge in TND, because of the fragility of the environment and the connection with human economic activities (TNDA, 2010; UNEP)
Economic activities in rural districts are predicated on natural resources, land, (Mayers and Vermeulen, 2002; TEEB 2010), Our operational connotation of economic activities “predominant primary economic activities, are livelihoods and economic gain in study area”.
Problem statement cont’dagriculture; wood fuel production;
hunting; illegal mining (galamsey); gravel and sand wining, amongst others.
Though extraction is important for human survival and maintenance, the increased human footprints (McCarthy, 2009), particularly land degradation is a call for greater concern (TNDA, 2010).
Theoretical basis of the study The complex interrelationships between
environment, economy and society (Adams, 2009).
Malthusian theory, increased population (human activities) for the demise of natural resource (Gausset and Whyte, 2005).

Research methods (profile of study area)
Research methods cont’d The cross-sectional design (Bryman,
2008). Mixed research strategy (triangulation) Both primary and secondary data types A purposive sample of 140 household pre-
coded questionnaires in communities Ten (10) Semi-structured interviews for
district dept. of Food and Agriculture (MOFA
quantitative data analyzing (SPSS) and qualitative data, thematically (inferential and descriptive statistics).

Results and Discussions cont’d The perception of land degradation is
highly linked with processes driven by the major land use types (economic activities) in the locality.

Invariably, it is conclusive that, land degradation is directly linked with primary economic activities, (UNEP, 2007).

Results and discussions cont’d Low economic development; agriculture
contributes 75% of LGDP (TNDA, 2010)- increased poverty and probably cause enhanced degradation
Lal (1999) 75 billion loss of soil and nutrient cost the world $400 billion per year.
Loss of surface cover (trees and grasses), economic trees like the Shea butter (Vitellaria paradoxa); Dawadawa, Baobab (Andansonia digitata) and Acacia sp.; Neem (Azadirachta indica) in the district.
Results and discussions cont’d Compounds nutrients loss hence
more dryness of the land (Waugh, 2005; Getis et al., 2005).
Increased money cost and time of household energy supply (TNDA, 2010).
Changes and/or variation in local climate, (TEEB, 2010).
Conclusions The land in TND is highly degraded
and there is high incidence of continual degradation- loss of soil fertility and visual degradation
Degrading processes are linked with primary economic activities; livelihoods and economic development.
Loss of land and it resources will have greater implications for sustainable development efforts in the district.
Recommendations Appropriate application of organic
manure and fertilizers, to restore loss and also prevent the depletion of soil nutrients.
Diversification of livelihoods; agro-forestry.
Foster effective licensing for illegal mining; gravel and sand wining.
Collaborative efforts on sustainable land use at community level.

THANK YOU FOR LISTENING!
Hmmm, is sustainable environment management possible in the light of increasing poverty?
