The effects of training, innovation and new technology on African smallholder farmers' economic outcomes and food security
  • Authors Ruth Stewart, Laurenz Langer, Natalie Rebelo Da Silva, Evans Muchiri, Hazel Zaranyika, Yvonne Erasmus, Nicola Randall, Shannon Rafferty, Marcel Korth, Nolizwe Madinga, Thea de Wet

  • PLS Title Training, innovation and technology interventions can improve livelihoods for smallholder farmers in Africa, but there are few rigorous studies
  • PLS Description Many poor people living in Africa depend on their small farms for survival. There has been a lot of interest in trying to reduce poverty in the region by supporting these farmers to produce more and make a profit from their farms. Such interventions include training farmers and introducing them to new farming techniques and products, such as new crop types or fertilisers. Although a substantial amount of money has been invested in these approaches by governments and international donors, the effects of these interventions on food security and economic outcomes are unclear. This review examines the effectiveness of training, innovation and new technology interventions on the economic outcomes and food security of smallholder farmers in Africa.

Effects of decentralized forest management (DFM) on deforestation and poverty in low- and middle-income countries

  • PLS Title Decentralized forest management programs can reduce deforestation rates but there is limited evidence to assess poverty outcomes
  • PLS Description An estimated 10–17 per cent of global carbon emissions are the result of deforestation. Forests also act as carbon sinks, absorbing carbon emissions from other sources. Therefore, preserving natural forests is an important component of managing climate change. Decentralized forest management programs transfer the responsibility and authority for managing forests (for example, deciding which areas are protected and which areas can be exploited) from central governments to local authorities. Such programs have the primary goal of reducing deforestation, but there is debate as to whether they can meet this goal while also reducing poverty. This review examines the evidence for the effects of decentralized forest management programs on deforestation and poverty outcomes in low- and middle-income countries.

The review summarizes evidence from 11 studies covering six PES programmes in four countries.

  • PLS Title Farmer field schools improve agricultural practices, yields and incomes in small pilot programmes, but not in large-scale programmes
  • PLS Description The purpose of farmer field schools is to improve farmers’ skills to empower them to make better decisions. Different programmes have different objectives, but they often aim to reduce pesticides use, promote better farming practices and boost yields or income. Field schools use facilitators who employ participatory, experiential learning methods over an entire growing season. For example, farmer field schools use ‘practice plots’ where farmers can compare results from different farming methods. In contrast to traditional agricultural extension projects, which mainly teach simple practices such as applying fertilisers, farmer field schools often teach holistic techniques, such as integrated pest management. Farmer field schools have been widely used across Asia, Africa and Latin America, reaching an estimated 10–15 million farmers. This review examines the effectiveness of farmer field schools in changing farmer knowledge and practice, and improving yields, income, environmental impact and farmer empowerment.

The impact of land property rights interventions on investment and agricultural productivity in developing countries
  • Authors Steven Lawry, Cyrus Samii, Ruth Hall, Aaron Leopold, Donna Hornby, Farai Mtero
  • Published date 2014-01-02
  • Coordinating group(s) International Development
  • Type of document Title Protocol Review Plain language summary
  • PLS Title Land property rights interventions improve agricultural productivity and investment in Latin America and Asia, but less in Africa
  • PLS Description Land property rights interventions improve agricultural productivity and investment in Latin America and Asia, but less in AfricaFarmers who have secure land rights can invest in long-term improvements to their farms without worrying that their land will be confiscated. Formalizing property rights may improve agricultural productivity, increase farmer income and improve access to credit. The most common approach to strengthening land rights in Latin America and Asia is to convert communal or non-demarcated rural land to freehold title, then register rights to the land in an official registry. In Africa, the more common approach is to demarcate and register existing customary rights. Underlying ownership remains with the state, and land sales are often restricted. This review examines the evidence on the impacts of such interventions on agricultural and livelihood outcomes in rural areas in low and middle-income countries.

Post-basic technical and vocational education and training (TVET) interventions to improve employability and employment of TVET graduates in low- and middle-income countries

  • PLS Title Technical and vocational education and training for young people has a small positive effect on employment outcomes.
  • PLS Description Many young people in developing countries work in low quality jobs that have low potential for career development or supporting economic growth. This is particularly problematic for developing countries given the continually significant labour productivity gap between developing and developed regions. With increasing emphasis on work and skills based solutions to economic completion and poverty there is a renewed focus on TVET. This review examines the effectiveness of these TVET interventions on employment and employability outcomes of young people in low- and middle-income countries, and which factors may moderate these effects.
