  • Slide 1
  • Tackling Land Degradation: A Prerequisite for Human Security Luc GNACADJA - World Future Council 2014 Inter-Parliamentary Regional Hearing on Exemplary Forest Policies in Africa Nariobi, 1 3 October 2014
  • Slide 2
  • Outline 1.Land degradation/Desertification? Human Security? 2.The tradeoffs in land use change: Progress or Degradation? 3.How LD threatens human security and global sustainability? 4.Restoring more than we degrade: Land degradation neutrality in the Sust. Dev. Goals (SDGs)
  • Slide 3
  • Desertification: a global challenge in a Vicious Cycle Land Degradation? Long-term loss of land (terrestrial bio productive syst.) productivity from which the land cannot recover unaided Desertification = Land Degradation in dry lands
  • Slide 4
  • A Vicious Cycle Causes of Land Degrad./Desertification Deforestation Overgrazing Unsustainable Agriculture Soil Erosion (Wind & Water)
  • Slide 5
  • Function change or Function trade off Forest Grassland 1. Undisturbed 2. Extensive 3. Intensive Tradeoffs in land use change: Progress or degradation? From trade-offs in Ecosystem functions towards Total degradation Source: PBL 2009
  • Slide 6
  • Function change or Function trade off Degraded? Forest Grassland 1. Undisturbed 2. Extensive 3. Intensive 4... Smart Policies needed to transform tradeoffs in synergies
  • Slide 7
  • Status & Trends in Global Land Degradation Source: SOLAW 2011 - FAO In too many places, achievements in production have been associated with management practices that have degraded the land & water
  • Slide 8
  • Human Security? Human Security (HS) concept connotes that of Human Development Human Security (HS) concept connotes that of Human Development Here, Security means freedom from fear, freedom from want and freedom to live in dignity. Here, Security means freedom from fear, freedom from want and freedom to live in dignity. Human security addresses human vulnerability and lack of resilience vis--vis security threats and risks in areas such as economic, food, health, environmental, personal, community, political. Human security addresses human vulnerability and lack of resilience vis--vis security threats and risks in areas such as economic, food, health, environmental, personal, community, political. Its a people-centered concept of security understood as necessary for national, regional and global security and stability. Its a people-centered concept of security understood as necessary for national, regional and global security and stability.

  • Migration main trajectories Major push factors of environmentally- induced migration: Drought Desertification Water Scarcity Environment degradation - Migrations & Conflicts Source: German Advisory Council on Global Change WBGU (2007)

  • Global Desertification Vulnerability Vulnerability to desertification: A migration push factor ? Desertification and drought global hot spots have become major global sources of environmentally- induced migrations
  • Slide 17
  • Drylands are not marginal lands The real value of Drylands 1/3 of the world land mass and population 44% of the Worlds food production system 50% of the Worlds livestock Dry forest made 42% of the earth's tropical and subtropical open or closed forests Home to the worlds largest diversity of mammals whose survival, literally, hangs on the arid zone forests

  • Land Degradation: Africa is most vulnerable region Risk of human-induced desertification From Land resource stresses and desertification in Africa Published in: P.F. Reich, S.T. Numbem, R.A. Almaraz and H. Eswaran, 2001 Weather shocks: the occurrence of droughts affecting over 2 M people has increased from 20% (1970s) to 90% (2000s) Social & resource-based conflict: Horn of Africa: home to over 4 million internally displaced and 2.5 million refugees due to war and drought Sahel region: home to over 500,000 internally displaced and 400,000 refugees Vulnerability is compounded by land degradation: over 3% of Africas agricultural GDP is lost annually equivalent to US$ 9 billion per year-as a direct result of soil and nutrient loss Over 45% of Africa was affected by desertification. 80% of the pasture & rangeland seriously eroded/degraded

  • Transformed landscape: Farmer-managed natural regeneration - FMNR
  • Slide 23
  • Underground forests: Tonys eureka moment in Niger FMNR = Farmer-managed natural regeneration, one of the most successful and cost- effective agro-forestry schemes for regenerating desertified land by managing living tree stumps & roots When you understand desertified land you can restore them (Tony Rinaudo)

  • Investments in Drylands can pay off Many drylands in developing countries have been investment deserts for too long, yet sustained higher levels of investment can enhance productivity and boost incomes. For the greatest gains, investments need to be configured to the short and long-term variability of these human-ecological systems. There are opportunities to suit all sectors For the public, private large-scale commercial, community and household, and private small-scale sectors Investments areas : renewable energy, education, health, water, farmland, pasture and livestock, woodland and trees, land use, conservation and tourism, urban development, markets, innovation and risk management, etc. The potential benefits of drylands (at local, regional & global levels) have not been fully utilized because of: Myths & stigma Market failures, Lack of public goods, Weak incentives, High investment costs and Gender inequalities.
