African agriculture is often dominated by smallholder farms composed of multiple plots. In policy circles it is often assumed that fragmentation coupled with small farm size is an impediment to increasing yields and thus decreasing poverty and food insecurity. There also exists an influential literature that explores the inverse relationship between farm size and yield. While there are many studies internationally, few have been conducted in Africa. Using an Ethiopian national survey, we explore the relationship between yield, farm size and fragmentation. We find an inverse relationship between farm size and yield, and a positive association between yield and land fragmentation.  相似文献

This paper analyzes how peasant movements scale up agroecology. It specifically examines Zero Budget Natural Farming (ZBNF), a grassroots peasant agroecology movement in Karnataka, India. ZBNF ends reliance on purchased inputs and loans for farming, positioning itself as a solution to extreme indebtedness and suicides among Indian farmers. The ZBNF movement has achieved massive scale not only because of effective farming practices, but because of a social movement dynamic – motivating members through discourse, mobilizing resources from allies, self-organized pedagogical activities, charismatic and local leadership, and generating a spirit of volunteerism among its members. This paper was produced as part of a self-study process in La Via Campesina, the global peasant movement.  相似文献

This paper examines the power to prorogue (or suspend) Parliament following the 2019 prorogation controversy in the UK. We outline the legal basis of prerogative-based prorogation, survey its uses in the UK and other Westminster systems, and compare it with equivalent rules in other European parliamentary democracies. The comparative perspective highlights the outlier status of the UK among comparable European democracies. In the UK, the absence of explicit legal limits on the use of prorogation gives the executive exceptional scope to employ the power for political purposes to sidestep Parliament. We conclude by discussing the implications of these findings for current discussions about the desirability of reforming the UK’s prorogation rules and placing express legal limits on the executive’s power.  相似文献

The profound socio-political crisis in El Salvador fully revealed itself in the events of 1979 and 1980, developing into an open civil war beginning on 10 January 1981. The conflict generated a series of profound changes in the social structure of the country (Segundo Montes, 1988:107).  相似文献

In this paper, we develop and test a general measure of policyexpenditures in the American states. Our approach is to constructa spatial proximity model of yearly state program spending.The empirical analysis reveals that state spending patternsvary along a clear and readily-interpretable unidimensionalcontinuum which differentiates policies that provide particularizedbenefits to needy constituencies from policies that providebroader collective goods. Based upon standard evaluative criteria,the variable created from our model possesses some highly desirablecharacteristics. And, it compares favorably to other measuresof state policy activity. The net result is a yearly score foreach state which summarizes that state's spending across allmajor program areas. More generally, we believe that our variablecan be interpreted as valid and reliable representational measurementof state policy priorities. In this capacity, it could occupyan important position within models of state politics. Author's note: Many colleagues provided useful feedback on earlierversions of this paper. We particularly appreciate the excellentcomments and suggestions from Robert Erikson, Richard Fording,Kim Hill, David Lowery, Andrea McAtee, and George Rabinowitz.We would also like to thank Daniel Lewis and William Myers fortheir assistance with the data collection. The yearly statepolicy priority scores obtained from the unfolding analysis,along with the data used to create the scores, the SAS macroto carry out the unfolding procedure, and all other supplemental materialsare available on the authors’ web sites: http://polisci.msu.edu/jacobyand http://polisci.msu.edu/schneider.

The purpose of the present study was to examine relations between adolescents’ social cognitions regarding parenting practices and adolescents’ prosocial behavioral tendencies. A mediation model was tested whereby the degree to which adolescents perceived their parents as responding appropriately to their prosocial and antisocial behaviors was hypothesized to predict adolescents’ tendencies toward prosocial behavior indirectly by way of adolescents’ prosocial values. Adolescents (N = 140; M age = 16.76 years, SD = .80; 64% girls; 91% European Americans) completed measures of prosocial values and of the appropriateness with which they expected their parents to react to their prosocial and antisocial behaviors. In addition, teachers and parents rated the adolescents’ tendencies for prosocial behaviors. A structural equation model test showed that the degree to which adolescents expected their parents to respond appropriately to their prosocial behaviors was related positively to their prosocial values, which in turn was positively associated with their tendencies to engage in prosocial behaviors (as reported by parents and teachers). The findings provide evidence for the central role of adolescents’ evaluations and expectancies of parental behaviors and of the role of values in predicting prosocial tendencies. Discussion focuses on the implications for moral socialization theories and on the practical implications of these findings in understanding adolescents’ prosocial development.  相似文献
