“…6), as can enhanced biotechnological (43) inputs. Recent research has suggested that investments in African agricultural development will lead to substantial propoor economic growth (43)(44)(45). Our analysis suggests that the continuation of recent tendencies will be likely to result in continued increases in undernourishment; but this is not a fait accompli.…”

Since 1980, the number of undernourished people in eastern and southern Africa has more than doubled. Rural development stalled and rural poverty expanded during the 1990s. Population growth remains very high, and declining per-capita agricultural capacity retards progress toward Millennium Development goals. Analyses of in situ station data and satellite observations of precipitation have identified another problematic trend: main growing-season rainfall receipts have diminished by Ϸ15% in food-insecure countries clustered along the western rim of the Indian Ocean. Occurring during the main growing seasons in poor countries dependent on rain-fed agriculture, these declines are societally dangerous. Will they persist or intensify? Tracing moisture deficits upstream to an anthropogenically warming Indian Ocean leads us to conclude that further rainfall declines are likely. We present analyses suggesting that warming in the central Indian Ocean disrupts onshore moisture transports, reducing continental rainfall. Thus, late 20th-century anthropogenic Indian Ocean warming has probably already produced societally dangerous climate change by creating drought and social disruption in some of the world's most fragile food economies. We quantify the potential impacts of the observed precipitation and agricultural capacity trends by modeling "millions of undernourished people" as a function of rainfall, population, cultivated area, seed, and fertilizer use. Persistence of current tendencies may result in a 50% increase in undernourished people by 2030. On the other hand, modest increases in per-capita agricultural productivity could more than offset the observed precipitation declines. Investing in agricultural development can help mitigate climate change while decreasing rural poverty and vulnerability.climate change ͉ drought ͉ famine ͉ precipitation

“…These studies generally find high poverty reduction elasticities for agricultural productivity growth (2). In Asia, it has been estimated that each 1% increase in crop productivity reduces the number of poor people by 0.48% (38). In India, it is estimated that a 1% increase in agricultural value added per hectare leads to a 0.4% reduction in poverty in the short run and 1.9% reduction in the long run, the latter arising through the indirect effects of lower food prices and higher wages (39).…”

A detailed retrospective of the Green Revolution, its achievement and limits in terms of agricultural productivity improvement, and its broader impact at social, environmental, and economic levels is provided. Lessons learned and the strategic insights are reviewed as the world is preparing a “redux” version of the Green Revolution with more integrative environmental and social impact combined with agricultural and economic development. Core policy directions for Green Revolution 2.0 that enhance the spread and sustainable adoption of productivity enhancing technologies are specified.

Other researchers also affirm this; among them are Hazell (2009);Rosegrant and Hazell (2000); Hazell and Haddad (2001); Lipton and Longhurst (1989); Thirtle et al (2003); Ravallion and Datt (1996);and Fan et al (2000). This policy push is premised on the fact that, " […] no Asian country developed its food staple agriculture from subsistence to market orientation without public intervention [....]" (Diao et al, 2007, p. 18).…”

This study examines the impact of technology adoption on food security in Sub-Saharan Africa. Using Ukum rural community, Benue State, Nigeria, as case study site which significantly represents other Nigerian-SSA farming communities, the study tracks the impact of farmers' adoption or non-adoption of improved technology on food security vis-à-vis factors shaping their choices. It aims to make the case that adoption boosts productivity and improves food security among others. Fifty farmer-participants were randomly selected using participant observation, structured interviews, questionnaires and photographing for data collection. Applying descriptive statistics including frequencies, tables, charts and percentages, field data were analyzed. Study findings strongly suggest that the main factors significantly affecting adoption of technology include cultural values, institutionalized land tenures, cropland size, poverty, literacy level, technology complexity, agricultural extension services, age and sex. Results suggest significant correlation between literacy level, economic power and technology adoption:younger, more educated farmers with higher economic status tend to adopt new technologies; farmers with access to agricultural extension services and credit facilities were more inclined to adopting new technologies; women were found more disadvantaged in the male-centered, exclusionary land tenure practice. Consequently, the study recommends sustained public sector interventions aiming to reduce food insecurity in the region.
