Waste not, warm not: Poverty, hunger and climate change in a circular food system por Brooks, Karen

“…The assumption is in part borne out by empirical evidence but, as is often the case, the full picture is more complex. Moreover, discussion of food loss and waste in terms of feeding the hungry misses the environmental benefits associated with better management of existing production. …”

Land, cows, and bullets: An untold history of cattle ranching during the armed conflict in Colombia, 1980–2010 por Triana Ángel, Natalia, Burkart, Stefan, Pazos Cárdenas, Mateo

“…Thus, this article contributes to the understanding of the history of cattle ranching in Colombia and to the complex transitional process in Colombia today. It demonstrates that productivity and efficiency have not always been the prevailing principles in the history of the cattle industry, but that land tenure and accumulation have operated as a way of securing power by the agrarian and political elites of the country. …”

Assessing the impact of agricultural research on poverty using the sustainable livelihoods framework por Adato, Michelle, Meinzen-Dick, Ruth S.

“…As the goals of international agricultural research move beyond increasing food production to the broader aims of reducing poverty, both agricultural research and studies of its impact become more complex. Yet examining the magnitude and mechanisms through which different types of agricultural research are able to help the poor is essential, not only to evaluate claims for continued funding of such research, but more importantly, to guide future research in ways that will make the greatest contribution to poverty reduction. …”

Facing the development challenge in Mozambique: an economywide perspective por Tarp, Finn, Arndt, Channing, Jensen, Henning Tarp, Robinson, Sherman, Heltberg, Rasmus

“…The need for a clear perspective and in-depth understanding of the socioeconomic complexities of the country in question stands out. However, while the analyses in this report are Mozambique specific, the basic analytical approach is replicable and could be brought to bear on other countries both within and outside Africa. -- From Authors' Introduction.…”

Living in the city: challenges and options for the urban poor por International Food Policy Research Institute

“…Relatively little is known about the determinants of urban food insecurity and malnutrition, but it is clear that the causes and the actors involved are more diverse and complex in urban settings than in rural ones. IFPRI and its collaborators are studying both the trends in urban food insecurity and manutrition and the causes, which operate at individual, household, and community levels. …”
