The paper analysed how climate change (CC) has shaped African agriculture in the past and how it might impact on African farm economies in the future and what adaptation strategies African farmers have adopted to cope with these changes. The analyses covered all key farming systems and agro-climates of Africa in 11 countries in which data were collected from over 10,000 farm household surveys. Results provided evidence that African agriculture and the welfare of its rural population are...

ABSTRACT Accelerating economic growth and social development is necessary to reduce the vulnerability and enhance the adaptive capacity of sub-Saharan Africa to cope with the consequences of predicted unfavorable future climate. This requires major investments and policy reforms to induce a needed radical transformation of the way development is currently pursued to a more climate-sensitive path of low carbon growth. Key gaps in the current knowledge base that call for major investments and...

Abstract A series of pollution control measures have been introduced to protect water quality in the Olifants river basin, the third most water-stressed and most polluted basin in South Africa. This paper employed an environmentally extended computable general equilibrium (CGE) model to analyse the economic and environmental implications of a tax on water pollution in the basin. Implications of increasing the pollution tax rate currently in place for the levels of economic activities and...

The Olifants river basin, which is one of the nine river basins in South Africa ranks as the third most water-stressed basin as well as the most polluted due to pollution from mining activities, irrigation agriculture, and industrial waste disposal. As a result, the government has implemented a series of pollution control measures with the view to mitigating pollution and water shortage in the basin. In this paper, we analysed the regional economic and environmental impacts of a tax policy...

SUMMARY The present study employed the Heckman sample selection model to analyse the two- step process of adaptation to climate change, which initially requires farmers' perception that climate is changing prior to responding to changes through adaptation. Farmers' perception of climate change was significantly related to the age of the head of the household, wealth, knowledge of climate change, social capital and agro-ecological settings. Factors significantly affecting adaptation to...

The study examines farmer adaptation strategies to climate change in Southern Africa based on a cross-section database of three countries (South Africa, Zambia and Zimbabwe).A multivariate discrete choice model was used to analyse the determinants of farm-level adaptation strategies.Results confirm that access to credit, free extension services, awareness of climate change are critical determinants of farm-level adaptation options.Policies aimed at easing identified key limits to farmers'...

This study measured the economic impacts of climate change on crop and livestock farming in Africa based on a cross-sectional survey of over 8000 farming households from 11 countries in east, west, north and southern Africa. The response of net revenue from crop and livestock agriculture across various farm types and systems in Africa to changes in climate normals (i.e. mean rainfall and temperature) is analysed. The analyses controlled for effects of key socioeconomic, technology, soil and...

Ethiopia remains one of the least-developed countries in the world: 50 percent of the population lives in abject poverty, and average life expectancy is only 43 years. Agriculture-the main sector of the Ethiopian economy-employs about 80 percent of the population and is dominated by small-scale, mixed crop and livestock production with very low productivity, which can be attributed to obsolete farming techniques; soil degradation caused by overgrazing and deforestation; poor complementary...

This paper analyses the vulnerability of South African agriculture to climate change and variability by developing a vulnerability index and comparing vulnerability indicators across the nine provinces of the country. Nineteen environmental and socio-economic indicators are identified to reflect the three components of vulnerability: exposure, sensitivity, and adaptive capacity. The results of the study show that the regions most exposed to climate change and variability do not always...

ABSTRACT This paper examines climate adaptation strategies of farmers in the Limpopo Basin of South Africa. Survey results show that while many farmers noticed long-term changes in temperature and precipitation, most could not take remedial action. Lack of access to credit and water were cited as the main factors inhibiting adaptation. Common adaptation responses reported included diversifying crops, changing varieties and planting dates, using irrigation, and supplementing livestock feed. A...
