Abstract

Despite annual climate variability threats, traditional farming in semi-arid Zimbabwe remains entrenched in unproductive, rain-fed agricultural practices. Adaptation strategies by farmers are seemingly failing to mitigate climate impacts, as evidenced by annual crop and livestock losses. Matabeleland South Province was a thriving livestock and small grain-producing province in the 1970s. Today, the province relies heavily on humanitarian assistance from government and humanitarian agencies. Through literature review, observations and focus group discussions with 129 farmers, the qualitative study established the perceptions of farmers around climate variability impacts in the past 20 years in Mangwe, Matobo and Gwanda districts in Zimbabwe. The study (1) analysed changes in climate and weather patterns in the past 20 years; (2) analysed climate impacts on traditional farming systems in the past 20 years in Gwanda, Mangwe and Matobo districts in Zimbabwe; and (3) established farmers’ perceptions, experiences and their climate adaptive strategies. The findings showed that the farmers experienced annual heat waves, protracted droughts, chaotic rain seasons, frost and floods, which led to environmental degradation. Traditional farming systems or practices have been abandoned in favour of buying and selling and gold panning, among other alternative livelihood options, because of climate-related threats and misconceptions around the subject of climate change. Farmers fail to access timely and comprehensive weather forecasts, resulting in annual crop and livestock losses, as decision-making is compromised. Given that the smallholder farming system sustains the bulk of the population in Matabeleland South Province in Zimbabwe, climate education and capital investment is needed to change traditional farmer perceptions about climate change impacts on the farming practices. Increased climate awareness initiatives, establishment of village-based weather stations and the marrying of traditional farming climate knowledge to modern practices are highly recommended to enhance resilience to climate.

The impact of climate change on smallholder and subsistence agriculture.

John Morton (2007)

Some of the most important impacts of global climate change will be felt among the populations, predominantly in developing countries, referred to as "subsistence" or "smallholder" farmers. Their vulnerability to climate change comes both from being predominantly located in the tropics, and from various socioeconomic, demographic, and policy trends limiting their capacity to adapt to change. However, these impacts will be difficult to model or predict because of (i) the lack of standardised definitions of these sorts of farming system, and therefore of standard data above the national level, (ii) intrinsic characteristics of these systems, particularly their complexity, their location-specificity, and their integration of agricultural and nonagricultural livelihood strategies, and (iii) their vulnerability to a range of climate-related and other stressors. Some recent work relevant to these farming systems is reviewed, a conceptual framework for understanding the diverse forms of impacts in an integrated manner is proposed, and future research needs are identified.
