The Efficiency–-Equity Tradeoffs in Agricultural Research Priority Setting: The Potential Impacts of Agricultural Research on Economic Surplus and Poverty Reduction in Nigeria AgEcon
Alene, Arega D.; Manyong, Victor M.; Tollens, Eric; Abele, Steffen.
Public agricultural research has come under increasing pressure to redefine its strategic priorities to contribute to poverty alleviation goals. However, the issue of whether the poor benefit more from agricultural research that pursues efficiency or equity objectives remains unresolved, largely due to lack of empirical evidence on the nature and magnitude of the efficiency–equity tradeoffs. This paper estimates the potential impacts of agricultural research on economic surplus and poverty reduction in Nigeria, identifies strategic priorities according to both efficiency and equity criteria, and examines the nature and magnitude of the efficiency–equity tradeoffs. The results show that there are no significant efficiency–equity tradeoffs because the rural...

Development and Dissemination of Improved Cassava Varieties in Uganda: Analysis of Adoption Rates, Variety Attributes and Speed of Adoption AgEcon
Abele, Steffen; Twine, Edgar; Ntawuruhunga, Pheneas; Baguma, Yonah; Kanobe, Charles; Bua, Anthony.
The transition out of extreme poverty and hunger in agrarian economies requires an understanding of how new agricultural technologies are adopted by poor farmers. In Uganda, improved germplasm from the cassava breeding program has generated new varieties that are increasingly being grown by farmers. Although considerable success has been achieved in adoption of these varieties in general, there is increasing pressure on breeding and technology dissemination programs to improve the targeting of their efforts. This paper identifies the specific cassava varieties adopted thus far and their desirable and undesirable attributes. In addition, it determines the adoption rates of these varieties and the factors that have influenced the speed of adoption of the...

Subsistence Agriculture in Central and Eastern Europe: Determinants and Perspectives AgEcon
Abele, Steffen; Voigt, Peter; Weingarten, Peter.
Subsistence agriculture in Central and Eastern Europe (CEE) has only recently gained interest from agricultural economists. Their origin, their future and even their definition is still not well elaborated. This paper tries to throw light on the issue of subsistence farming in CEE. It first discusses the theoretical and empirical background of subsistence agriculture. This part is followed by a typology of subsistence farming as found in CEE. Analysis considers several hypotheses on the cause of subsistence agriculture, among them the structure of land ownership, market imperfections and lack of alternative income sources or low opportunity costs of labour respectively. Of all these hypotheses, only the latter can be proofed empirically, which is done by a...

Development of Agricultural Market and Trade Policies in the CEE Candidate Countries. AgEcon
Sepp, Mati; Gorton, Matthew; Miglavs, Andris; Kazlauskiene, Natalija; Meyers, William H.; Guba, Waldemar; Ratinger, Tomas; Safin, Marius; Simon, Françoise; Bozik, Marian; Michalek, Jerzy; Banse, Martin; Ferenczi, Tibor; Bojnec, Stefan; Turk, Jernej; Dalton, Graham E.; Turtoi, Crina Sinziana; Vincze, Maria-Magdolna; Davidova, Sophia; Ivanova, Nedka Momtscheva; Mishev, Plamen Dimitrov; Abele, Steffen; Frohberg, Klaus; Hartmann, Monika; Matthews, Alan; Weingarten, Peter.
This synthesis report focuses on the evolution of agricultural market and trade policies in the Central and Eastern European (CEE) candidate countries in the period 1997 to 2001. The developments were crucially influenced by (OECD, 2000a): • the situation in world agricultural markets; • the overall macroeconomic development in the countries considered; • the prospective EU accession; • bringing domestic agricultural policy in line with the Uruguay Agreement on Agriculture (URAA). High 1997 agricultural prices on world commodity markets were followed by a marked depression in 1998. With the exemption of milk products this trend continued in 1999. Likewise the economic and financial crisis in Russia had a considerable impact on agricultural policies. It hit...

Subsistence Agriculture in Central and Eastern Europe: How to Break the Vicious Circle? AgEcon
Abele, Steffen; Frohberg, Klaus.
Subsistence agriculture is probably the least understood and the most neglected type of agriculture. In a globalised, market-driven world, it remains at the same time a myth and a marginal phenomenon. Empirically, subsistence agriculture for a long time seemed to be restricted to developing countries, with only a few cases reported in Western Europe (CAILLAVET and NICHELE 1999; THIEDE 1994). Governmental support offered to subsistence agriculture was mainly done through agricultural development policies, the main objective being to have subsistence farmers participate in markets. The strategy was to make farmers produce more by introducing new technologies and consequently bring their output to the market. Failures of such attempts were numerous, yet...

Agricultural trade for food security in Africa: A Ricardian model approach AgEcon
Diagne, Mandiaye; Abele, Steffen; Diagne, Aliou; Seck, Papa Abdoulaye.
Regionalism and food security is a relatively neglected topic with very limited literature. We use a Ricardian trade model with multiple goods and countries which embeds a structure of gravity equation and yield variability. Our study shows that integration with African markets of staple foods is associated with higher growth, underpinning the need for growth strategies to emphasize scaling up and diversifying exports within Africa. Africa needs to unlock its high potential untapped land and fill up the yield gap. We found as well that enhanced competitiveness and reduced barriers to trade are the two critical areas of action.

The Niger Food Crisis: Causes and Implications for Research and Development from an Integrated Agricultural Economics Perspective AgEcon
Abele, Steffen; Twine, Edgar.
During the 2004 food crisis in Niger, the weakness of the main production system, millet, to produce enough food to sustain short term crises, has been revealed. Questions arise how the Nigerian smallholder systems can be assisted by research and development policies to intensify production and improve food security. The paper assesses technical options according to their economic sustainability. A sequence of models is applied: On plot level, production functions of inter cropping systems were estimated to determine yields and their variability of the major crops. These data were fed in a nonlinear program to test the inn ovations, first at stable prices, then at declining prices that were obtained from an interregional trade model. The latter was shocked...
