National and regional diversity assessment, conservation strategies and cost effectiveness of in situ conservation options

Mauritius, South Africa and Zambia produced CWR checklists (table 1) and prioritized CWR for conservation (table 2). A partial checklist on food and fodder crops was also developed at regional level (table 1) and prioritized (table 2). Checklists and occurrence data for priority CWR are available from the project's Dataverse site.

Results of diversity assessments and conservation planning have been instrumental to develop national strategic actions plans (NSAP) in all three countries. The Zambian government has endorsed the  NSAP (15.8 MB) in January 2017. The NSAPs are currently in the process of being endorsed by the respective governments in Mauritius and South Africa.

Results of the regional diversity assessment and conservation planning are available here [to be published].

An assessment of cost effectiveness of in situ conservation options for CWR was carried out in Zambia, involving surveys of CWR on farm and on communal lands in 26 local communities. Result of this study are reported here.

3.1: Compile baseline information on diversity, conservation status and threat of targeted CWR in the three partner countries and at regional SADC level

3.2:  Identify regional and national in situ CWR hotspots and priority sites for in situ conservation and ex situ collection validated through expert interviews and field visits using innovative GIS technology

3.3: Predict which CWR in situ populations and materials from ex situ collections have traits adapted to extreme climate conditions (e.g. heat, drought) using predictive characterization

3.4: Develop exemplar National Strategic Action Plans (NSAP) on in situ conservation and use of priority CWR in three participating countries

3.5: Assess cost effectiveness of in situ conservation options
