Protection of water infrastructure
What do you see? What impacts can it have? What can be done?

...3R examples?

Field surveys of biomass of savannas
• Savanna = open vegetation with mix of trees, shrubs and grass
• A biomass survey could look at each component
Can you think of some characteristics of savannas that pose opportunities or threats to field biomass surveys?
NB there are also remote sensing methodsNB there are also remote sensing methods

Exercise resource use patterns
1. What general adaptive management strategies can pastoralists use?
2. What examples of specific activities do Maasai have for each strategy?
3. Which of the strategies/activities would you classify as 3R?
What do you see? What impacts can it have? What can be done?

Diversification of uses and sources
Lessons from WASHEC? Diversification: where and how?
![Page 22: 3R Environmental considerations](https://reader038.vdocuments.us/reader038/viewer/2022110309/5584ca7cd8b42ae0138b4bf7/html5/thumbnails/22.jpg)
Assessment of 3R alternatives
Many 3R activities require investment (resources, time)
Those resources could have been used for other (more pressing) activities
Benefits occur mostly in the long run
Under these circumstances the important question is: is it worthwhile?
![Page 23: 3R Environmental considerations](https://reader038.vdocuments.us/reader038/viewer/2022110309/5584ca7cd8b42ae0138b4bf7/html5/thumbnails/23.jpg)
Use of discounting
Now?
Tomorrow!

Stakeholder accounts
Not all costs and benefits are borne by the same people
Carefully look at individual (group) perspectives
SUSWA project contributions
BUT for spontaneous adoption: financial analysis must take all costs and benefits into account
Return to labour is an important factor

Building an account
• Investment
• Maintenance
• Production
Compare ‘with’ with a without situation

Wrap up
Stakes in diversification (community / AMREF / WASH Alliance)?
Opportunities for experiential learning?
Having a first go at developing 3R for a practical case
3R = thinking in terms of environmental opportunities

Adapt and enjoy 3R
