Introduction
As social scientist with 15 years experience in crop livestock farming research, inclusive market oriented development and innovation systems approaches, I believe in the potential that exists in African drylands. My research contributes to understand and change the conditions that lock smallholder farming systems in vulnerable states of low production and not reward investments. I draw on experience in trans-disciplinary research projects, inspired by transformative change theories.

The Central Mozambican provinces are climatically quite diverse. While some provide farmers with favourable environments, others make agriculture a complicated and risky endeavour for the hard-working and persistent. In Marara district, in Tete province, the climate is semi-arid, around 600 mm of rain fall every year, but mostly in two months. In E...

Crop–livestock farming systems that are predominant in Africa, are complex with various interrelated ecological and economic factors. They involve multiple products or benefits (intended and nonintended), with trade-offs and synergies occurring both on- and off-site and varying over time. Understanding both simplistic relationships and complex inte...

Article
Full-text available
African mixed crop–livestock systems are vulnerable to climate change and need to adapt in order to improve productivity and sustain people’s livelihoods. These smallholder systems are characterized by high greenhouse gas emission rates, but could play a role in their mitigation. Although the impact of climate change is projected to be large, many...
Article
A “Gender Control Tool” was developed to measure women’s control over decision-making for agricultural production, sales, and use of income. The tool was tested for groundnuts in Eastern Province, Zambia, where mechanisation has increased male participation in groundnut shelling, and for goats in Gwanda district, Zimbabwe, where the introduction of...
Article
We explore the relationship between commercialisation and gender for groundnuts in Eastern Province, Zambia, using a mixed methods approach. Women saw themselves as having greater control over groundnuts than other crops, and both sexes saw groundnuts as controlled by women. Propensity Score Matching showed that machine shelling and higher sales di...

In semi-arid Zimbabwe livestock play a vital role in the livelihoods of small-scale farmers. Current productivity is low due to various inefficiencies, but there is a huge potential for farmers to obtain significant incomes from strategic sales and improved management. Climate variability and change are a threat, especially through negative impacts...

Smallholder farming systems like in semi-arid Zimbabwe face short and long-term challenges induced by variable and changing climate. Short-term benefits must be complemented with long-term sustainability goals. Current productivity levels are extremely low, institutional support systems weak and value chains not fully functional. As a result most o...

We explore the meaning of 'women's crops' in Sub-Saharan Africa using a simple tool to measure women's control. We tested the tool for groundnuts in Eastern Province, Zambia, using both qualitative and quantitative methods. Women saw themselves as having greater control over groundnuts than over sunflower, maize, and cotton. Despite differences in...

Crop residues (CR) have become a limited resource in mixed crop-livestock farms. As a result of the increasing demand and low availability of alternative resources, CR became an essential resource for household activities, especially for livestock keeping; a major livelihood element of smallholder farmers in the developing world. Farmers’ decisions...

Despite the importance and opportunities that cattle present to smallholder farmers, their productivity remains low. High mortality and low fertility mainly caused by feed and health related factors are the reasons of low cattle productivity in semi-arid Zimbabwe.

Conservation Agriculture (CA) is being advocated to enhance soil health and sustain long term crop productivity in the developing world. One of CA’s key principles is the maintenance of soil cover often by retaining a proportion of crop residues on the field as mulch.

Archived project
This study seeks to engage stakeholders at different levels in exploring the impacts of climate change and possible adaptation options for smallholder farming systems in semi-arid Zimbabwe. We communicate with stakeholders at various stages in the research process, set up of future scnearios and adaptation options, reflection of results and design of messages that are intended to influence decisions towards enabling better adaptation to climate change. Through stakeholder engagement and simulation modeling we link climate change projections with socio-economic and biophysical changes, for more plausible futures. Working together with stakeholders at different levels from the onset of the project is intended to come up with research information that is useful for making informed decisions, for the design of short term technical solutions, and longer term institutional and policy options.
