The gendered effects of agricultural practices on land degradation and restoration in two contrasting agro-ecological zones of Cameroon
Social–ecological transformations towards sustainability in drylands
Drylands face urgent development challenges that are complex and interconnected, requiring holistic systems-based approaches. Here, we present a social–ecological systems framework to guide research, policy, and action across disciplines and sectors towards sustainability transformations in drylands for improved livelihoods and enhanced ecosystem, livestock, and human health. Our conceptual framework integrates three non-exclusive and complementa…
Integrating Earth observation, biophysical, and survey data to evaluate the ecological impacts of a common land protection and restoration intervention in Rajasthan, India
Approximately, one-quarter of India’s land area comprises common-pool resources, e.g., pasture land, forests, and water bodies, upon which the livelihoods of over 300 million rural people depend. Despite their importance, these resources are subjected to encroachment and degradation, raising important questions about what can be done to promote their protection and restoration. Since 2001, the Foundation for Ecological Security (FES) has worked w…
Realizing soil health for food security in Africa
Enhancing co-production of knowledge
Shifting the relationship between science and decision making is a key challenge for sustainable development. We conducted a two-part behavioural study linked to the preparation of the Kenya Agroforestry Strategy. Two virtual workshops followed a data visualisation preference survey of 174 technical officers to compare the influence of a peer-led and a facilitated workshop on inclusive, evidence-based decision making. A post-workshop survey, faci…
Inclusive, Cross-Sectoral and Evidence-Based Decision-Making for Resilience Planning and Decision-Making in a Devolved Context
Successfully achieving the sustainable development goals requires addressing complex, interrelated, wicked problems across multiple scales and contexts and decision-making that tackles nested layers of goals and targets across the interrelated social, economic and environmental dimensions of sustainability. The Stakeholder Approach to Risk-informed and Evidence-based Decision-making (SHARED) bridges processes, tools and accessible evidence to sup…
Assessing the downstream socioeconomic impacts of agroforestry in Kenya
Agroforestry is widely purported to improve the livelihoods of smallholder farmers, rehabilitate degraded landscapes, and enhance the provisioning of ecosystem services. Yet, evidence supporting these longer-term impacts is limited. Using a quasi-experimental impact evaluation design informed by a theory-based and mixed methods framework, we investigated selected intermediate and final outcomes of a nine-year effort led by Vi Agroforestry, a Swed…
Soil carbon 4 per mille
The ‘4 per mille Soils for Food Security and Climate’ was launched at the COP21 with an aspiration to increase global soil organic matter stocks by 4 per 1000 (or 0.4 %) per year as a compensation for the global emissions of greenhouse gases by anthropogenic sources. This paper surveyed the soil organic carbon (SOC) stock estimates and sequestration potentials from 20 regions in the world (New Zealand, Chile, South Africa, Australia, Tanzania, In…
Breaking Ground
Mapping of soil organic carbon stocks for spatially explicit assessments of climate change mitigation potential
Current methods for assessing soil organic carbon (SOC) stocks are generally not well suited for understanding variations in SOC stocks in landscapes. This is due to the tedious and time-consuming nature of the sampling methods most commonly used to collect bulk density cores, which limits repeatability across large areas, particularly where information is needed on the spatial dynamics of SOC stocks at scales relevant to management and for spati…
