N3-ICARDA+suitability+mapping

In collaboration with ICARDA, the Nile-Goblet tool is adjusted for high resolutions and tested for the Maksegnit watershed

persons involved : Kibruyesfa Sisay, ARARI Gondar center, Catherine Pfeifer, Yenenesh Abebe

//evapotranspiration// || icarda rainfall station are only one year, but high resolution and precise. we propose to compare the results with the 2 others source of data we have. The soil map needs to be generated based on the data collection from ICARDA. This can be a time intensive work... || flow accumulation < ??? soil depth and fertility aridity index <0.65 || slope from DEM flow accumulation map soil depth/fertitilty aridity index (FAO) || flow accumulation map needs to be generated from elevation. || erosion status Slope between 12-58% Not on forest, not on settlements soil type (?) || rainfall layer (same than crop) soil erosion layer (from ICARDA soil) slope from DEM landuse from ICARDA || rainfall might not be necessary as it the whole area might fall in the relevant range || slope 10- 50% Not forest not settlements || rainfall same than crop soil erosion land use ||  || slope 3-15% not on degraded land || rainfall same as crop slope from DEM soil erosion ||  || slope 5-35% || rainfall same than crop slope stoniness of the soil (derived from ICARDA soil map) ||  || proximity to homestead || //river map// //(settlement map)// //existing well map/ponds// //soil depth// //altitude// || a settlement map could be done based on google earth. About 3000 households live in the watershed, generating this map could be very time intensive. || topographic index (water saturation) || topographic index < 0.8 (threshold to be validated based on the existing wells map) river layer ||  || livestock intensity ||  || livestock intensity might not be relevant as all the farmers mentions food shortage as an issue = no need for prioritizing Also it might be very difficult to say something about spatially explicit livestock intensity in a small watershed || river map ||  || river map ||  ||
 * ponds || slope < 5%
 * Bench terracing || Rainfall < 1400mm
 * Hillside terracing || Rainfall < 900mm
 * soil bunds || rainfall < 1400 mm
 * Stone bund || rainfall < 1400 mm
 * home gardens/papaya || access water
 * hand dug wells || proximity to non perennial river (200 m)
 * Ficus thonningi (Chibha) || proximity to homestead,
 * small scale irrigation || slope<5%, proximity to the perennial river (1km) || slope
 * "spate irrigation" || slope<5%, proximity to the non-perennial rivers (1 Km) || slope

Action plan **(in bold what needs to be done before coming to Addis)**
 * 1) **get exact crop requirement data (Kibru, to be cross-checked with Teklu in Addis)**
 * 2) get reanalyis data from Cornell (Catherine)
 * 3) **get soil data as detailed as possible, row and processed (Kibru)**
 * 4) **LGP check resolution and relevance (Catherine)**
 * 5) //check feasibility of doing an evapo-transpiration map based on sun radiation, land cover (=10 m resolution) (Kibru)//
 * 6) check resolutions of available evapo transpiration maps (Catherine)
 * 7) **get the river map (Kibru), make sure that perennial and non-perennial is part of the attribute table (ev. add with experts of from FGD N3)**
 * 8) **well map (coordinates of the existing wells) (Kibru)**
 * 9) **ponds map (Kibru)**
 * 10) create a settelment map (based on imagery/google earth), to be decided later on if really necessary
 * 11) topographic index at 10 m resolution (Catherine to ask Abisa or Solomon), check the Grass options
 * 12) create the flow accumulation map (Kibru, to be crosschecked with Solomon in Addis)
 * 13) **check data for livesock in the N3 dataset (Catherine)**

meeting with Teklu and Solomon about crop modeling/ topographic index/ flow accumulation/evapotranspiration finalizing suitability criterias and map selection processing the soil data, rainfall data, preparing layer for the tool populating the Nile Goblet tool for high resolutions testing the suitability maps running the final suitability, short reporting
 * Plan for Addis**
 * Day 1**
 * Day 2**
 * Day 3**
 * Day 4**
 * Day 5**

an additional day is needed to produce the evapo transpiration map or the settlement map digitized from Google earth if it turns out that we need this information.
