In the second of our climate resilience themed blog posts (read out first one here!), we take a look at the different watershed management approaches used by projects to address both climate change adaptation and mitigation. First, we visit Morocco for an introduction to the adaptation work undertaken by the Global Diversity Foundation’s plant conservation programme in the Atlas Mountains. We then travel half way around the world to see the Natural Bolivia Foundation’s watershed project and the impact it is having on livelihoods, deforestation and climate resilience in the Chaco.
Conserving threatened plant species to support community adaptation and resilience to climate change in the High Atlas
The Mediterranean ecosystem of the High Atlas in southern Morocco is home to significant plant biodiversity – including endemic, endangered and economically important species – that has been sustained for millennia by Indigenous Amazigh communities. However, High Atlas cultural landscapes are under increasing threat from interrelated socio-ecological problems that include overharvesting of endemic useful plants, intensive grazing, inadequate water management and the erosion of cultural practices of conservation and sustainable land use management. The effects of climate change, heightened in fragile montane ecosystems, are compounding the impact of all these factors.
In April 2017, Global Diversity Foundation began implementing a three-year Darwin Initiative project. One of the ways the project is seeking to improve the resilience and adaptation of local communities to climate change is by building and restoring water management infrastructure to provide more efficient irrigation of large tracts of agricultural land and community nurseries in partner communities. This contributes to climate change adaptation in partner communities whilst also ensuring that precious water resources are used wisely and can therefore continue to sustain the broader ecosystems within which these agricultural terraces are embedded. To support this work, the project team collaborate with diverse partners to provide training courses for local communities and associations on cultivating drought resilient crops and using water economically to improve resilience to climate change and increasingly arid conditions.
As part of this programme, the Global Diversity Foundation are establishing community seed banks to secure improved availability of locally adapted plant species, and carrying out research on the impact of climate change on the High Atlas flora to identify potential new climate change refugia for target endangered or endemic plant species. The results of this research will inform our ongoing conservation actions in the High Atlas. All of these activities enrich partnerships with Amazigh people, who continually assess the impacts of climate change on their cultural landscapes and devise further strategies to lessen its effects on their socio-ecological wellbeing.

Watershared: adaptation, mitigation, watershed protection and economic development in the Bolivian Chaco
Bolivia’s Gran Chaco encompasses swamps, salt flats, scrublands, and the largest virgin dry forest on earth. Although the region offers high soil fertility, it receives minimal rainfall. Most of the economic activity in Chaco requires water, so there is an urgent need to increase water efficiency and, most importantly, ensure that the water arrives in the lowlands in the first place.
Upper watershed farmers in the Chaco often have no economic alternative other than to deforest their land for agriculture. Forests are destroyed and cows enter streambeds to drink, forage, urinate and defecate. The subsistence agriculture of upper watershed farmers is unproductive, while downstream water sources are contaminated. Children miss school with diarrhoea as a result of contaminated water, and waterholes dry up.
Reciprocal watershed agreements – otherwise known as Watershared agreements – are simple, grassroots versions of incentive-based conservation. They help upper watershed forest and land managers to sustainably manage their forest and water resources to benefit both themselves and downstream water users. Watershared agreements focus on changing behaviour through economic and non-economic incentives and building institutional capacity: in other words, by showing local authorities and water users that watershed protection is in their own interests, and then facilitate the creation of the institutional framework needed to plan and implement it.
The Watershared model was first developed in 2003, in the Bolivian village of Los Negros. Six downstream irrigators negotiated a ground-breaking deal with their upstream counterparts. “For every 10 hectares [ha] of forest you conserve for a year,” Andrés Rojas told Serafín Carrasco, “we will give you a beehive and training in how to produce honey.” And so the first reciprocal watershed agreement was struck. The Reciprocal Watershed Agreements Darwin Project helped another six municipal governments create and consolidate Local Water Funds. These funds were designed to catalyse local investment in the upstream “Water Factories” of the Chaco and thereby simultaneously:
- Mitigate climate change (conserve old growth forests);
- Adapt to climate change (maintain water sources);
- Increase food security (maintain quantity of irrigation water and diversify upstream production systems); and
- Improve human health (enhance water quality).
Most importantly, by having water users and municipal governments pay for the conservation activities, the project developed the institutional framework for sustainable financing of climate change mitigation and adaptation activities. In addition to the 96,510ha that the project conserved under Reciprocal Watershared Agreements, there was a high demand from local authorities for the creation of new municipal protected areas. The project used Darwin Initiative funds, along with counterpart support, to help create three new municipal protected areas. The creation of these areas protected another 500,000 ha of the Chaco’s forests.
