"This article analyzes the on-site and off-site economic impacts of various sustainable land management (SLM) practices in Kenya. Long-term trial data are used to establish the relationship between SLM practices and maize yield. The analysis of on-site effects focuses on the profitability of maize production at the farm level, while the examined off-site effects include carbon sequestration and siltation from maize farms, which increase the cost of potable water production.

Strategies for sustainable agricultural development in the East African highlands

Low agricultural productivity, land degradation and poverty are severe interrelated problems in the East African highlands. While the proximate causes of such problems are relatively well known, the underlying causes are many and complex, and depend upon many site-specific factors that vary greatly across the diverse circumstances of the region. In this paper, we argue that the appropriate strategy for sustainable development depends greatly upon the “pathways of development” that are feasible in a given location.

It examines the effects of (1) a major devaluation of the Brazilian real (R$); (2) improvements of infrastructure in the Amazon to link it with the rest of Brazil and bordering countries; (3) modification of land tenure regimes in the Amazon agricultural frontier; (4) adoption of technological change in agriculture both inside and outside the Amazon; and (5) fiscal mechanisms to reduce deforestation." -- from Author's Abstract

Der Welthunger-Index (WHI) 2014 stellt die nationale, regionale und weltweite Hungersituation zum neunten Mal in jahrlicher Folge multidimensional dar. Er zeigt, dass bei der globalen Hungerbekampfung seit 1990 Fortschritte erzielt werden konnten, jedoch angesichts sehr ernster oder gar gravierender Hungerwerte in 16 Landern noch immer groser Handlungsbedarf besteht. Der Schwerpunkt dieses Berichts liegt auf einem entscheidenden Aspekt des Hungers, der haufig ubersehen wird, dem verborgenen Hunger.
