and central Ethiopian highlands. Whilst global causes for climate change were debated with <strong>in</strong>creas<strong>in</strong>g<br />
controversy on various <strong>in</strong>ternational platforms, Ethiopia prepared itself for the next drought.<br />
Measures taken <strong>in</strong>clude among others<br />
• Improvement and expansion of the national and regional road network<br />
• Establishment of a strategic food reserve<br />
• Plan for Accelerated and Susta<strong>in</strong>ed Development to End Poverty (PASDEP)<br />
• A large-scale soil and water conservation supported by a series of Integrated Food Security<br />
Projects (IFSPs) and the Productive Safety Net Program (PSNP)<br />
• Promotion of zero/controlled graz<strong>in</strong>g practice<br />
How will global warm<strong>in</strong>g and climate change<br />
affect the region <strong>in</strong> future?<br />
• Global warm<strong>in</strong>g may result <strong>in</strong> a change of<br />
climatic conditions rang<strong>in</strong>g from drought to<br />
excessive ra<strong>in</strong>fall and flood hazards.<br />
• Total annual ra<strong>in</strong>fall may not necessarily decrease,<br />
but may even <strong>in</strong>crease.<br />
• Ra<strong>in</strong>fall variability is likely to <strong>in</strong>crease ren<strong>der</strong><strong>in</strong>g<br />
crop and livestock production a much more risky<br />
endeavour.<br />
• Commonly applied farm<strong>in</strong>g practices (agriculture)<br />
may fail and lead to crop failure, poor livestock<br />
production and food shortages.<br />
Climate change adaptation pr<strong>in</strong>ciples<br />
• Apply measure to reduce vulnerability of communities and households to climate change<br />
• Apply measure to realize opportunities of climate change<br />
• Harvest and store ra<strong>in</strong>fall and runoff w ater<br />
- Where it falls - on hillsides, on farmland, <strong>in</strong> planes<br />
- When it falls - before it causes erosion<br />
- As much as possible and economically and ecologically feasible<br />
- Where it is needed - <strong>in</strong> the soil - through low cost <strong>in</strong>-situ water harvest<strong>in</strong>g techniques<br />
- Selectively apply more costly ex-situ water harvest<strong>in</strong>g structures (household ponds, cisterns,<br />
earth dams)<br />
• Capacity build<strong>in</strong>g of agricultural extension services<br />
• Awareness creation among farm<strong>in</strong>g communities<br />
• Improve weather <strong>in</strong>formation system and weather forecasts<br />
• Introduce a climate hazard (crop and livestock) <strong>in</strong>surance<br />
Community-based participatory watershed management<br />
S<strong>in</strong>ce 1986 75 per cent of the surface area of Tigray exposed to soil erosion has been treated with terraces.<br />
After experienc<strong>in</strong>g higher annual ra<strong>in</strong>fall over the past five years, terrac<strong>in</strong>g and deep trench<strong>in</strong>g is<br />
commonly applied on hillsides as well as on farmland. Further <strong>in</strong>-situ water harvest<strong>in</strong>g techniques have<br />
been developed and tested. Gully treatment is common. All physical measures applied on hillsides,<br />
farmland and <strong>in</strong> gullies are comb<strong>in</strong>ed with biological rehabilitation measures ensur<strong>in</strong>g short-term benefits<br />
