The green revolution in Zimbabwe

Jane Alumira, Joseph Rusike [ 2005 ]
This paper presents a historical overview of plant breeding research, variety release and seed supply of staple food grains in Zimbabwe, and assesses the impacts of the new varieties on yields using national aggregate yield data. The paper also analyses [...]

The maize green revolution in Kenya revisited

Hugo De Groote, George Owuor, Cheryl Doss, James Ouma, Lutta Muhammad and K. Danda [ 2005 ]
The maize green revolution, which increased maize yields through the use of improved varieties and fertilizer, has stalled since the mid-eighties in Kenya. This paper examines whether the stagnation of yields continued in the 1990s in spite of the implementation [...]

Has Green Revolution bypassed coarse cereals? The Indian experience

Aldas Janaiah, Lalith Achoth, Cynthia Bantilan [ 2005 ]
This paper analysed the growth performance of non-rice crop sectors by estimating total factor productivity (TFP) growth for the selected coarse cereals viz., maize, sorghum and pearl millet in India. The analysis indicates that the TFP growth contributed substantially to [...]
It is widely believed that a Green Revolution similar to the one achieved in Asia is impossible in Sub-Saharan Africa. Although grain yields have been stagnant in this region, there are some signs of the intensification of farming systems in [...]

An overview and prospects for a green revolution in Sub-Saharan Africa

Keijiro Otsuka, Kaliappa P. Kalirajan  [ 2005 ]
While population still continues to grow rapidly in Sub-Sahara Africa, the expansion of cultivation area has slowed down considerably due to the increasing scarcity of uncultivated land. Since the yield of food grain per unit of land has remained largely [...]

Investing in agriculture for growth and food security in the ACP countries

Jakob Skoet, Kostas Stamoulis, Annelies Deuss [ 2004 ]
Countries in the ACP region will face significant challenges in the years to come as they try to step up economic growth, deal with increasingly integrated world markets and meet the Millennium Development Goals (MDGs), especially those focused on hunger [...]

Will buying tropical forest carbon benefit the poor? Evidence from Costa Rica

Suzi Kerr, Alexander Pfaff, Romina Cavatassi, Benjamin Davis, Leslie Lipper, Arturo Sanchez, Joanna Hendy  [ 2004 ]
We review claims about the potential for carbon markets that link both payments for carbon services and poverty levels to ongoing rates of tropical deforestation. We then examine these effects empirically for Costa Rica during the 20th century using an [...]
This paper presents the construction of a spatially explicit, nationally disaggregated measure of poverty over time in Costa Rica. The paper first describes the two possible methods considered for the construction of a poverty map: principal component analysis (PCA) versus [...]

Effects of poverty on deforestation: distinguishing behaviour from location

Suzi Kerr, Alexander Pfaff, Romina Cavatassi, Benjamin Davis, Leslie Lipper, Arturo Sanchez, Jason Timmins [ 2004 ]
We summarize existing theoretical claims linking poverty to rates of deforestation and then examine this linkage empirically for Costa Rica during the 20th century using an econometric approach that addresses the irreversibilities in deforestation. Our data facilitate an empirical analysis [...]

Understanding vulnerability to food insecurity: Lessons from vulnerable livelihood profiling

Christian Romer Løvendal, Marco Knowles, Naoko Horii [ 2004 ]
The Food Security and Agricultural Projects Analysis Unit (ESAF) of FAO has undertaken a number of pilot studies to develop a methodology for understanding why certain groups of people are vulnerable to becoming food insecure. The studies use the sustainable [...]
