Policy brief: Land degradation in Kenya
This policy brief aims to give an overview of land degradation hotspots in Kenya and the policy options for land restoration. In this assessment, land degradation is referred to as the persistent loss of ecosystem function and productivity caused by disturbances from which the land cannot recover without human intervention (unaided). Hotspots are defined as places that experience high land degradation and if left unattended, will negatively affect both human wellbeing and the environment.
The spatial location of hotspots was identified through a methodology combining modelling and field validation. Understanding the spatial locations helps identify hotspot areas and target them as priority intervention sites for restoration with relevant management options.
This national level policy brief is complemented by three other detailed policy briefs focusing on the counties of Bungoma, Siaya, and Kakamega. In addition, this policy brief is supported by a detailed comprehensive assessment report which can be accessed at this link: https://cgspace.cgiar.org/handle/10568/9716

Land Degradation Assessments Using Multiscale Hierarchical Approaches for Agroecosystem Restoration and Improved Food Security: The Case for Kenya and Burkina Faso
This report provides a synthesis on land degradation assessments conducted for two countries (Kenya and
Burkina Faso) at different scales. The task mainly involved identifying hotspot areas of degradation that require priority management interventions. The approach involves modelling, stakeholder engagement and field validation.
In the report, we refer to land degradation as the persistent loss of ecosystem function and productivity caused by disturbances from which the land cannot recover unaided.
Hotspots refer to places that, if left unattended, could prove harmful, both to the environment and to those dependent on it. These areas generally require priority management interventions due to the severity of the degradation problem and its associated cost. Considering the fact that land degradation processes differ across space and over time and that there will be no ‘one-size-fitsall’ approach to assess the severity of the problem and its spatial distribution, a multiscale hierarchical approach was followed. At the national level, we used time series satellite and rainfall data to trace the spatial distribution of land degradation and identify the major drivers (human caused versus climate induced). Results from such exercise would benefit national level planning and decision making. In addition, development organizations, donors and NGOs can benefit from such results to target their interventions. At the county/province/district level, we developed an ‘index’ that can help map land degradation risks using relatively higher resolution data. Such products can be beneficial to county/district level planners as well as stakeholders whose activities are relevant to this scale. The third and more detailed level of analysis employs a spatially distributed hydrological model to map land degradation hotspots at landscape and/or farm levels and assess the impacts of land management options. Outputs from this analysis can be used by development agents, extension workers as well as local communities and farmers to facilitate targeted decision making. The above sequential steps clearly demonstrate the need for context-specific analysis that fit to local and regional conditions. In addition to the modelling and analysis results, the report provides recommendations for farmers, policy makers, decision and development agents and researchers regarding the implications of the land degradation findings towards identifying technical, policy and institutional arrangements that will promote land restoration, agroecosystem health and food security in order to meet current and future human and environmental sustainability objectives

OS-WALK-EU: An open-source tool to assess health-promoting residential walkability of European city structures
Introduction This paper introduces OS-WALK-EU, a new open-source walkability assessment tool developed specifically for urban neighbourhoods and using open-source spatial data. A free and open-source tool, OS-WALK-EU is accessible to the general public. It uses open data available worldwide and free online services to compute accessibility, while at the same time allowing users to integrate local datasets if available. Based on a review of existing measurement concepts, the paper adopts dimensions of walkability that were tested in European city environments and explains their conceptualization for software development. We invite the research community to collaboratively test, adopt and use the tool as part of the increasing need to monitor walkability as part of health-promoting urban development.
Methods Tool development is based on spatial analysis methods to compute indicators for five dimensions of walkability: residential density, weighted proximities to amenities, pedestrian radius of activity, share of green and blue infrastructure, and slope. Sample uses in the cities of Dublin, Düsseldorf and Lisbon test the validity of input data and results, including scenarios for target groups like older people.
Results Overall, application of the tool in Dublin, Düsseldorf and Lisbon shows conclusive results that conform to local knowledge. Shortcomings can be attributed to deficiencies in open source input data. Local administrative data, if available, is suitable to improve results.
Conclusions OS-WALK-EU is the first software tool that allows free and open walkability assessments with pedestrian routing capacities for ‘proximity to facilities’ calculations. Large scale implementation for 33 German city regions in an online application shows the value of comparative assessments of walkable neighbourhoods between urban and suburban neighbourhoods. Such assessments are important to monitor progress in a mobility transition towards improved walkability and public health
Results and Impacts of the Integrated Land and Water Management for Adaptation to Climate Variability and Change (ILWAC) Project: Evaluation Report
The objective of the evaluation was to assess the results and impacts of the activities of all ILWAC Trust Fundfinanced projects in West Africa using a selected subset, to identify key lessons learned, and to document best climatesmart practices for scaling up. The study entailed participatory evaluation of the results and impacts of various
interventions geared towards integrated water resources management for climate change and variability preparedness
in West Africa. In this respect, the study identified key lessons learned and documented best climate-resilient practices
for scaling up and dissemination to multiple stakeholders in the West African region.
1. Agriculture remains the backbone for sustaining livelihoods in West Africa but faces numerous challenges.
Agriculture is an important source of income, food and raw materials in West Africa, employing more than half of
the region’s population, which culminated in the adoption of the Comprehensive Africa Agriculture Development
Programme (CAADP) in 2003. Few countries, however, have managed to mobilize their agriculture sector to
deliver on development outcomes such as food and nutrition security, poverty reduction, economic growth, job
creation, youth employment and industrialization. Agriculture is vulnerable to climate change, resulting from
sensitivity and exposure to climate shocks and lack of capacity to cope with and adapt to such changes. ILWAC
evaluation study results from household surveys, focus group discussions and key informant interviews indicate
that agricultural productivity in the region remains low, lagging far behind other regions of the world. Contributors
to such low productivity include incidence of climate risks (drought, floods and high temperatures), pests and
diseases, low technology adoption, limited access to financial services, limited access to markets and market
information and limited access to good road networks (Plate 1). All the aforementioned contributors are valid
denominators for all the seven ILWAC project areas that were evaluated.
2. Farmers in West Africa are particularly vulnerable to climatic shocks because of their high dependence on
rainfed agriculture for their livelihoods. There is an evident lack of access to formal safety nets as indicated by
farmers in Senegal (ENRACCA-WA) and Burkina Faso (AmREACCAF and APESS) projects. Climate change has
already exerted significant impacts in the region. Since the 1970s, the region has experienced the occurrence of
many droughts. Temperatures have increased in the second half of the 20th Century, especially in the latter 20
years of the same period. Farmers reported drought (about 40% of treatment and control groups), as the most
prevalent climatic shock experienced over the last five years, followed by erratic rainfall, floods and invasion of
crop pests and locusts. We identified eleven coping strategies, out of which three strategies were categorized based
on a gradient of severity of food insecurity into low, moderate, and high food insecurity. During low food
insecurity, households employ food-maximizing strategies such as purchasing food and eating less food and
involving a low commitment of domestic resources that all enable quick recovery of households once the crisis
eases. In times of moderate food insecurity, a greater commitment of household resources is increasingly required
to meet subsistence needs. Coping strategies developed by households include sale of food reserves, use of savings,
sale of livestock, borrowing food, and borrowing money (from friends, relatives, private lenders and banks).
During high food insecurity, strategies are a sign of failure to cope with the food crisis and may involve drastic
options that may undermine their future ability to prevent, mitigate, cope, and recover from shocks. Households
adopt sale of assets such as land and homes, keeping children home from school, food aid and migration. The use
of irrigation and rainfall water harvesting for agriculture remain low, despite prevalent droughts and widespread
rainfed agricultural practices. One of the reasons is that most farming communities are far from rivers: hence
considerable investment is required to develop irrigation in many project areas.
3. Although farmers use various strategies highlighted above, they will need support to double their efforts with
innovative climate- smart agricultural practices and technologies to remain food secure. Areas where ILWAC
interventions were targeted showed positive results, but broader efforts to scale out the successes are needed to achieve
a greater impact. Overall, the ILWAC project beneficiaries reported higher adoption rates of climate-smart practices,
demonstrating a favourable impact of the project. However, low awareness of the most appropriate technologies to cope
with climate shocks was reported across all study areas yet, the region is expected to experience increasing climatic
shocks with total precipitation predicted to increase for the most part more notably between July and October by 2050.
Increases in precipitation are predicted to cause crop damages and floods. Overall, temperatures will rise by about 2°C
to 3°C over the same time period. Higher temperatures of 3°C to 6°C are projected for the end of the 21st century
(Niang et al., 2014). Despite these impending changes, few farmers have adjusted their farming strategies in response to
climate risks, owing to limited knowledge on appropriate adaptation options and low endowment with production
resources. As a result, ILWAC interventions were targeted to reverse these challenges. Their successful implementation
showed positive results, which are largely limited to specific areas of implementation. Therefore, broader scaling out ILWAC interventions provided success stories tailored to specific contexts (biophysical and socio- economic); hence
offered lessons and opportunities for replicating the bright spots with a regional approach. Across the seven projects,
evaluation results indicated a couple of selected successes in the region (Plate 1). Selected successes make up
potential candidates for scaling up climate-smart agricultural technologies and practices, and innovative approaches
notably, including:
i. Innovation platforms as a pillar for change: The successful establishment of innovation platforms across all
project countries was evident but have remained largely underdeveloped and not utilized to their full potential.
Platforms provided a framework for sharing knowledge on adaptation innovations to climate change, providing
a good entry point for technology dissemination in target areas across all project countries. The study showed
that the innovation platform model can offer the potential to organize stakeholders to address the objective of
improving the livelihood of their members. IPs, however, need a strong voice to demand the needed services
from service providers, negotiate and advocate for collective interests with the private sector and government.
The use of a participatory development communication (PDC) within IPs would greatly increase their
sustainability;
ii. Increased human and institutional capacity for stakeholders: The enhancement of capacity for diverse
stakeholder groups, including farmers, players in all segments of priority value chains, extension agents,
policymakers and researchers (All project countries) resulted in significant positive results such as increased
capacity towards awareness of CSA technologies and application of appropriate adaptation measures in their
communities. This highlights the need to prioritize linkages amongst farmer organizations, extension and
agricultural research;
iii. Integrated landscape approaches for natural resources management provided exponential benefits: The
pioneering of integrated land and water management for adaptation to climate variability and change improved
management of natural resources in specific target countries, for example, in Burkina Faso, the relative
reduction in sedimentation by up to 70%; and that in reduced runoff by up to 30% which helped improve the
farmers’ agricultural practices and livelihoods (AmREACCAF-Burkina Faso). This also increased storage of
water in the Boura reservoir through avoided sedimentation. Beyond water provision for household use, these
reservoirs serve as key food baskets for fisheries and irrigation for households;
iv. Integrated and diversified options offered opportunities to increase resilience and unlock the potential
for rural smallholder livelihoods: The ILWAC project improved implementation of innovative agronomic
interventions that substantially reduced the yield gap for millet for example the use of improved crop varieties
(drought tolerant and early maturing) resulted in a 10 fold yield increase in grain biomass (ENRACCASenegal). Additional strategies include soil amendments in the form of organic and inorganic fertilizer sources,
weed control practices as well as improved storage techniques (ISFM-Benin); Household enterprise
diversification with agroforestry tree species enhanced the resilience of smallholder communities with climatesmart benefits such as windbreaks, these modified the micro-climate of the area that enhanced food security and
revenue generation within target communities, increased farmer adaptive capacity and overall soil health attributes (ENRACCA- Senegal). 5. Women empowerment resulted in improved rural livelihoods: Improved gender dynamics regarding the roles,
activities and representativeness within the selected projects had a positive impact on women empowerment for all
project countries. There are numerous ways by which women were empowered e.g. conducting off-season
vegetable cultivation allowed women to fetch increased returns (3 times than the normal price) in the off-season
months. There were efforts to promote increased participation of women in the projects, offering opportunities to
freely express themselves, highlight their needs and specific experiences. However, participation of women in
leadership positions was generally low (less than 10%). In addition, women were able to benefit from the capacity
building provided by the project, and access technologies and inputs resulting in higher production and subsequent
incomes than before. Male-headed households were more likely to practice more CSA technologies by a factor of
about 1 compared to female headed households. There was evidence of better access to financial services and
training through village savings and loan associations, and gender empowerment. A key attribute of the assessed
projects was that for the most part, women farmers were not well organized into interest groups with the capacity to
promote their interests and engage in advocacy activities geared at influencing policy for their ultimate benefit.
This was a missed opportunity especially in the context of existing innovation platforms that needs concerted
efforts and strengthening.
6. More economic and social safety nets for smallholder livelihoods beyond ILWAC beneficiaries are needed:
ILWAC enhanced farmers’ access to climate-resilient and low-emission practices and technologies, including crop,
livestock, soil and water management options and energy saving technologies. ILWAC increased the number of CSA
practices implemented by three practices more compared to non-participation. Results further showed that education level is
associated with higher income. Higher value assets such as livestock did also significantly influenced income. ILWAC
increased significantly the value of assets to almost 90%; a factor attributable to additional assets that were distributed to
farmer groups such as the case of Gambia, Senegal and Sierra Leone. This study therefore confirms that more assets in
ILWAC supported households offered better livelihood options than those in the control group. Results further show that
male-headed households have a higher value of assets than female-headed households. On the overall, although participation
in ILWAC increased income by 19%, there remains room for further improvement amongst the ILWAC beneficiaries given
the lower differences in the economic domain for sustainable intensification exemplified before and after the ILWAC project
on Plate 2. Likewise, Plate 2 highlights that better options are needed in the social domain to ensure that ILWAC
beneficiaries can significantly gain from social dividends (e.g. strengthened farmer groups, collective action, and shared
labor). Given the highlighted successes among the ILWAC beneficiaries, efforts will be needed to scale these bright spots
beyond the ILWAC beneficiaries to wider geographical coverages.
7. There is need for concerted efforts towards supporting technical, financial, institutional and governance
needs within the target countries in order to make community livelihoods more resilient to climate change.
Despite the recorded successes there remains room for improvement in several institutional and governance realms.
Farmers in the project sites are faced by poor extension, with the ratio of government paid extension officers to that
of farmers being low, only 33% of the households have access to extension service. This has a negative impact on
the quality of extension services being offered and building adaptive capacity to deal with climate change.
A significant challenge remains in all project countries to get the technologies widely used due to the lack of a
suitable enabling environment among others — extension services, financial resources, infrastructure, risk
management and cross-sectoral linkages. Farmers are further constrained by having limited access to climatic
information. Effective research and innovation are also needed to continuously improve practices and technologies.
This calls for a policy recommendation where concerted efforts are needed to mobilize financial resources and
build the capacity of West African researchers, policy-makers and institutions to understand, carry out and use
good quality data towards informed decision making and scenario analyses (Also see evidence revealed by Plate
2).Enabling policy and institutional environment can provide the conditions and incentives for scaling out
