Simulating Small-Scale Agricultural Adaptation Decisions in Response to Drought Risk: An Empirical Agent-Based Model for Semi-Arid Kenya

In Eastern Africa, increasing climate variability and changing socioeconomic conditions are exacerbating the frequency and intensity of drought disasters. Droughts pose a severe threat to food security in this region, which is characterized by a large dependency on smallholder rain-fed agriculture and a low level of technological development in the food production systems. Future drought risk will be determined by the adaptation choices made by farmers, yet few drought risk models … incorporate adaptive behavior in the estimation of drought risk. Here, we present an innovative dynamic drought risk adaptation model, ADOPT, to evaluate the factors that influence adaptation decisions and the subsequent adoption of measures, and how this affects drought risk for agricultural production. ADOPT combines socio-hydrological and agent-based modeling approaches by coupling the FAO crop model AquacropOS with a behavioral model capable of simulating different adaptive behavioral theories. In this paper, we compare the protection motivation theory, which describes bounded rationality, with a business-as-usual and an economic rational adaptive behavior. The inclusion of these scenarios serves to evaluate and compare the effect of different assumptions about adaptive behavior on the evolution of drought risk over time. Applied to a semi-arid case in Kenya, ADOPT is parameterized using field data collected from 250 households in the Kitui region and discussions with local decision-makers. The results show that estimations of drought risk and the need for emergency food aid can be improved using an agent-based approach: we show that ignoring individual household characteristics leads to an underestimation of food-aid needs. Moreover, we show that the bounded rational scenario is better able to reflect historic food security, poverty levels, and crop yields. Thus, we demonstrate that the reality of complex human adaptation decisions can best be described assuming bounded rational adaptive behavior; furthermore, an agent-based approach and the choice of adaptation theory matter when quantifying risk and estimating emergency aid needs.

Inclusive and climate smart business models in Ethiopian and Kenyan dairy value chains (CSDEK)

This booklet presents sixteen 'practice briefs' which are popular publications based on 12 Master and one Bachelor theses of Van Hall Larenstein University of Applied Sciences (VHL). All theses were commissioned through the research project entitled 'Inclusive and climate smart business models in Ethiopian and Kenyan dairy value chains (CSDEK)'. The objective of this research is to identify scalable, climate smart dairy business models in the context of the ongoing transformation from informal to formal dairy chains in Kenya and Ethiopia.

RESILIO Final report

In today’s city environments, extreme weather conditions are a fact oflife. Amsterdam, Mumbai, Nairobi or Sydney… climate change issuesneed to be tackled all around the world.In the last couple of decades, Amsterdam has dealt with largeramounts of rainwater, severe heat stress and a decreased biodiversity.In order to strengthen urban resilience to climate change, blue-green(BG) roofs are increasingly being introduced. BG roofs placean additional water layer underneath the green layer. The idea is thatthese roofs reduce runoff after rainfall by retaining precipitation andmitigate heat stress, caused by increased evapotranspiration (the sumof evaporation from the land surface and transpiration from plants)and a higher albedo effect (the ability of surfaces to reflect sunlight).

Alumni impact of Dutch knowledge institutions on dairy chain governance in Kenya and Ethiopia

This booklet presents twenty-one impact stories of Ethiopian and Kenyan alumni of Dairy (Livestock) trainings in the Netherlands. The Dutch trainings consists of Master courses conducted by Van Hall Larenstein University of Applied Sciences (VHL) in Wageningen or Velp, short courses or diploma courses organised by Practical Trainings Centre (PTC+) in Oenkerk or Barneveld / Dairy Trainings Centre (DTC) in Oenkerk and short courses organised by Centre of Development Innovation – part of Wageningen University and Research Centre (WUR) in Wageningen. Most refresher course participants attended the Dutch trainings between 2010 and 2018. These alumni attended the Refresher Course entitled “Assessing the impact of Dutch knowledge institutions on performance of Netherlands alumni on dairy value chain governance in Kenya and Ethiopia” organised by Van Hall Larenstein University of Applied Sciences (VHL), Agrikom (alumni organisation) and Egerton University on 7-16 July 2019 in Nairobi and Nakuru, Kenya. Part of the refresher course was dedicated to a write shop about the impact of the Dutch training. It was written in collaboration with the professorship Climate Smart Dairy Value Chains.

Adaptive governance by community based organisations

Adaptive governance describes the purposeful collective actions to resist, adapt, or transform when faced with shocks. As governments are reluctant to intervene in informal settlements, community based organisations (CBOs) self-organize and take he lead. This study explores under what conditions CBOs in Mathare informal settlement, Nairobi initiate and sustain resilience activities during Covid-19. Study findings show that CBOs engage in multiple resilience activities, varying from maladaptive and unsustainable to adaptive, and transformative. Two conditions enable CBOs to initiate resilience activities: bonding within the community and coordination with other actors. To sustain these activities over 2.5 years of Covid-19, CBOs also require leadership, resources, organisational capacity, and network capacity. The same conditions appear to enable CBOs to engage in transformative activities. How-ever, CBOs cannot transform urban systems on their own. An additional condition, not met in Mathare, is that governments, NGOs, and donor agencies facilitate, support, and build community capacities. This is the peer reviewed version of the following article: Adaptive governance by community-based organisations: Community resilience initiatives during Covid‐19 in Mathare, Nairobi. which has been published in final form at doi/10.1002/sd.2682.
