Identification de caractéristiques agronomiques pour le diagnostic et la prise de décision de régénération des vergers de cacaoyers en Côte d’Ivoire

The rehabilitation of the old cocoa ( Theobroma cacao L. ) farms is one of the major challenges for a sustainable cocoa production. A study was carried out to set up a guide which could be used as a decision making tool for a quick and efficient diagnosis of the old cocoa orchards and to choose the appropriate regeneration option (rehabilitation or replanting). A sample of 90 rehabilitated cocoa farms and of 75 replanted cocoa farms was surveyed in 12 regions representing the three main cocoa producing sectors in the country. Data were collected on the key agronomic characteristics of these cacao farms. These were cocoa variety, farm size, age, yield, planting density, number of shade trees and the level of damages caused by insects and diseases. The results showed that age, planting density and yield were the discriminating criteria of these farms. The average values of these criteria were 25 to 30 years for the age, 800 to 1 000 trees ha-1 for the planting density and 250 to 400 kg ha-1 an-1 for the yield. Based on these criteria and their average values, a decision making guide was designed for the diagnosis of cocoa farms and the choice of regeneration option. According to this guide, old cocoa farms (more than 25 years), degraded and unproductive should be replanted. However, younger farms having planting density and yield higher than the average values above should be rehabilitated.

The impact of household size on poverty: An analysis of various low-income townships in the Northern Free State region, South Africa

Poverty is a multi-dimensional socio-economic problem in most sub-Saharan African countries. The purpose of this study is to analyse the relationship between household size and poverty in low-income communities. The Northern Free State region in South Africa was selected as the study region. A sample of approximately 2 900 households was randomly selected within 12 poor communities in the region. A poverty line was calculated and 74% of all households were found to live below the poverty line. The Pearson’s chi-square test indicated a positive relationship between household size and poverty in eleven of the twelve low-income communities. Households below the poverty line presented larger households than those households above the poverty line. This finding is in contradiction with some findings in other African countries due to the fact that South Africa has higher levels of modernisation with less access to land for subsistence farming. Effective provision of basic needs, community facilities and access to assets such as land could assist poor households with better quality of life. Poor households also need to be granted access to economic opportunities, while also receiving adult education regarding financial management and reproductive health.
