Abstract:In the Global South, there is a push to drive agricultural modernisation processes through private sector investments. In West African drylands, land concessions are required for such agri-businesses are often negotiated through customary authorities, and inject large amounts of money into localised rural systems with low cash bases. The article argues that such transactions serve to increase area under crop cultivation on an inter-seasonal basis, as financial spill-overs allow for farmers to purchase larger quantities of agricultural inputs and prepare larger tracts of land. Simultaneously, such direct and indirect cash flows also result in larger local herd sizes and an increase in the number of locally-owned cattle, as cash is exchanged for cattle, largely regarded as an interest-accruing, savings buffer. Larger herd sizes, in turn, attract Fulani pastoralists in search of employment as contracted herders for local cattle owners. Taking Integrated Water and Agricultural Development (IWAD), a private sector, large-scale irrigation initiative in northern Ghana as a case study, the article argues that there is an inevitability of the pathway, which leads from large-scale land acquisitions in West-African drylands, to an increase in conflict (and/or the risk thereof) between sedentary and Fulani pastoralists.

Improving water supply for irrigable farming and livestock purposes in communities in Africa is an increasingly popular approach for community-based adaptation interventions. A widespread intervention is the construction of agro-pastoral dams and irrigation schemes in traditionally pastoral communities that face a drying climate. Taking the Maji Moto Maasai community in southern Kenya as a case study, this article demonstrates that water access inequality can lead to a breakdown of pre-existing social capital and former pastoral cooperative structures within a community. When such interventions trigger new water uses, such as farming in former pastoral landscapes, there are no traditional customary institutional structures in place to manage the new water resource. The resulting easily corruptible local water management institutions are a main consolidator of water access inequalities for intervention beneficiaries, where socio-economic standing often determines benefits from interventions. Ultimately, technological adaptation interventions such as agro-pastoral dams may result in tensions and a high fragmentation of adaptive capacity within target communities.

Agro-pastoral dams (APDs) are an increasingly popular method of adaptation interventions improving communal water supply in rural West Africa. However, APDs are often constructed in areas where culturally heterogeneous pastoralists and farmers compete for similar land and water resources. Lifting open access water abundance is likely to change if not intensify ongoing tensions between farmers and settling Fulani herders. The extent of collective action and inclusivity of 6 APDs in Northern Ghana are analysed, combining theory from common-pool resource management and equity and justice in climate change adaptation into a proposed Inclusive Collective Action (ICA) model. Practically, the article demonstrates that neither fully excluding Fulani pastoralists nor making dams openly accessible results in inclusive APD usage and management where collective action is successful, and more dynamic forms of regional inclusion and exclusion are needed. Theoretically, the article identifies some of the limitations of applying the enabling conditions for collective action of common-pool resource theory as it tends to overlook negative aspects of excluding certain user groups in culturally heterogeneous contexts from managing and using a commons.

<p>Droughts are long-lasting and have a range of cascading impacts on society. These impacts and their responses can influence the further development of the drought itself, but also continue into the period after the drought ended. Especially if society is hit by a next hydrological extreme event, heavy rainfall resulting in flooding, the effects of this may be increased or decreased by the preceding drought and its impacts and responses. We here present a review and a global assessment of cases of these events, based on scientific literature, NGO and governmental reports, and newspaper articles, to study the diversity of how drought affects flood risk. We find that the balance between the positive and negative effects of extreme rainfall after a long dry period is mostly dependent on the underlying vulnerability and the effect of specific responses, and is different for different countries, and for different sectors and groups in society. Based on our initial analysis of the collection of case studies, we see some emerging patterns. For example, in Europe, the USA and Australia, the highly managed water system with hard infrastructure and early-warning systems makes that in most cases the rainfall after drought are managed and adverse effects mitigated, but also lock-ins exist that can make feedbacks of either inaction or maladaptation result in increased economic losses. In Africa and Latin-America, with a fragile governance system, less hard infrastructure, and a more exposed population, extreme rainfall after drought brings relief and replenishment of water resources, but also increased impacts, conflict and displacement. Here, we hypothesise that impacts are unequally distributed in society, because of issues of power, access to land and water resources, inadequate soft infrastructures, etc. We will test this hypothesis with an in-depth qualitative study of local stakeholder knowledge of these human-water processes in selected case studies. The typology of drought-to-flood events that we developed can serve as a starting point for further research on the complexity of these cascading events.</p>
