A preliminary diagnostic study of agricultural and environmental conservation activities in the Tabacaria quilombola community, located in the rural zone of Palmeira dos Índios, Alagoas, Brazil, the only such community officially recognized by the state, used monthly participatory meetings, a questionnaire, and site visits to assess potential locations for a community garden. The diagnosis found an absence of technical assistance or guidance from any public agency and a lack of information reaching the community. Agriculture remained subsistence-based, centered on cassava, corn, beans and fava beans, with ecological soil and water management practices practically nonexistent. The study calls for awareness-raising and information activities to address these gaps and for the development of sustainable agricultural practices.

A study assessing concentration levels of lead (Pb), cadmium (Cd) and sulphides (SO2) within and around Gweru's sole official waste dumpsite in Zimbabwe. Harsh economic conditions in the city have driven further expansion of urban agriculture on open spaces, with residents growing staple food crops such as maize and sweet potatoes for subsistence on numerous plots surrounding the dumpsite; the study states that ingesting crops grown near the dumpsite is likely to put residents' lives at risk. Soil sampling points along transects on and around the dumpsite were randomly selected using ArcView GIS, with sulphide concentrations measured by Leco machine and lead and cadmium by atomic absorption spectrometer. Independent t-test results showed the concentration levels of the three pollutants were significantly elevated from one sampling point to the next, within and around the dumpsite.

Using FAOSTAT data from 2000 to 2005, this panel data analysis examines the impact of the food production index (FPI) on the food consumer price index (CPI), the agricultural labor force (ALF), and rural-urban and agricultural-nonagricultural populations in South Asia. While food production in the region increased, food prices also rose sharply, producing an undesirable dual impact in countries where net consumers outweigh net producers: consumers lose while producers gain. A random effects model was found more appropriate, and results indicate consumer protection, CPI, and ALF are country-specific determinants of food production.

Dzodzi Tsikata · · Sub-Saharan Africa

This chapter examines urban women's livelihoods in sub-Saharan Africa since the 1990s, focusing on economic liberalization and the expansion of the informal economy. Urban agriculture, including home gardens, is identified as an increasingly important activity within this informal sector. Many women in the urban informal economy are employed by others or have been in the past, while industrial subcontracting, a source of informal employment, has been significant only in a few industrialized Sub-Saharan African countries.
