2.5 Country/ region/ locations where the Technology has been applied and which are covered by this assessment

2.6 Date of implementation

If precise year is not known, indicate approximate date:

• less than 10 years ago (recently)

2.7 Introduction of the Technology

Specify how the Technology was introduced:

• through projects/ external interventions

Comments (type of project, etc.):

2009

3.1 Main purpose(s) of the Technology

• reduce, prevent, restore land degradation

3.2 Current land use type(s) where the Technology is applied

Land use mixed within the same land unit:

Ja

Specify mixed land use (crops/ grazing/ trees):

• Agro-silvopastoralism

Comments:

Principaux problèmes d'utilisation des sols (perception des utilisateurs fonciers): absence d'activités agricoles et de patures à cause d'une forte salinisation des sols et de la nappe

Usage futur (final) de la terre (après la mise en œuvre de la technologie SLM): Mélangé: Mp: Agro-pastoralisme

Comments:

Principales mesures: Structures physiques

3.7 Main types of land degradation addressed by the Technology

Comments:

Type principal de dégradation adressée: Cs: salinisation / alcalinisation

Types de dégradation secondaires abordés: Bc: réduction de la couverture végétale, Hg: modification dans les nappes phréatiques et aquifères

Principales causes de dégradation: déforestation / disparition de la végétation naturelle (inclusive les feux de forêts), la surexploitation de la végétation pour l'usage domestique (surexploitation liée à la pauvreté), sécheresses, autres Causes naturelles (avalanches, éruptions volcaniques, topographie extrême, coulée de boue, etc.) Spécifier. (Intrusion de l'eau salée)

Causes secondaires de la dégradation: pression de la population, pauvreté / santé, gouvernance / institutionnel (absence de conventions en rapport avec l'utilisation des ressources naturelles et octroi de permis aux allochthones)

3.8 Prevention, reduction, or restoration of land degradation

Specify the goal of the Technology with regard to land degradation:

• restore/ rehabilitate severely degraded land

Comments:

Objectifs secondaires: prévention de la dégradation des terres, atténuation / réduction de la dégradation des sols
