“…Holden et al (2003) predict that allowing farmers to plant eucalyptus on land unsuitable for crop production in a community in North Shewa could increase household incomes by at least 30%, with little impact on soil conservation incentives or erosion of farmland. Okumu et al (2002) predict that allowing eucalyptus planting on uncultivated slopes in a watershed close to Addis Ababa, along with other technological interventions focusing on improved vertisol management, could increase household cash incomes substantially and reduce soil erosion, even if eucalyptus prices were to fall substantially.…”

Sub-Saharan Africa (SSA) has the lowest agricultural productivity in the world, while almost half of the population lives below US$1 per day. The biggest development policy challenge is to find appropriate solutions to end hunger and poverty in the region. Building on several years of empirical research conducted in East Africa, this paper identifies potential strategies for sustainable development in this region. In general, the empirical evidence reviewed confirms that different strategies are needed in different development domains of SSA. Nevertheless, some elements will be common to all successful strategies, including assurance of peace and security, a stable macroeconomic environment, provision of incentives through markets where markets function, development of market institutions where they do not, and public and private investment in an appropriate mix of physical, human, natural, and social capital. The differences in strategies across these domains mainly reflect differences in the mix of those investments as influenced by different comparative advantages.

“…The problem is further aggravated by climate variability and change, population pressure, limited use of sustainable land management (SLM) practices, deforestation, rugged terrain characteristics, erratic rainfall, vulnerable soil and heavy dependence on rain-fed agriculture [7,8]. The on-site cost due to erosion of top soil is estimated to be 2.0-6.75% of Ethiopia's agricultural GDP per annum [9,10].…”

Smallholder farmers can adapt to climate variability and change through sustainable land management (SLM) practices that help to offset the negative impacts at farm level. However, use of these practices as adaptation strategy remains low in Ethiopia in general and the study sites in particular. This study aimed at examining the factors that determine farmers' decision to use SLM measures and to quantify the impact of the practices on crop productivity at household and plot level. The study was based on household-and plot-level primary data and employed nearestneighbor matching technique to quantify the impact of using the practices on value of production at household level and plot level. The results revealed that households that implemented SLM practices within the period (2004-2009) experienced a 24.1% higher value of production over non-users in 2016. Similarly, plots that received SLM measures within the period (2004-2009) experienced a 28.6% increase in value of production in 2016. The study also made further analysis at plot level using continuous treatment effects in order to take into account the number of years a plot has been under the practice. The result showed plots with SLM structure that are maintained for at least 6 years have a positive increase in value of production at the end of the 6th year, while those that received the practices recently or those that lacked continuous maintenance did not experience a statistically significant increase in value of production. The result also showed marginal benefit of sustaining the SLM practices increases over time at an increasing rate. The implication is that use of SLM measures and maintenance of the structures are crucial to reap significant benefits from the practices. Although value of production increases given the SLM practices, implementation is labor intensive and there is trade-off with other agricultural activities. Therefore, policy measures are required to incentivize implementation and maintenance of the SLM structures.

“…Other approaches, such as fertilizer credit and promotion of off-farm employment, had either limited or negative impacts on productivity and were predicted to reduce farmers' investments in SWC and increase erosion, leading to trade-offs between income and sustainability objectives. Okumu et al (2002) reached similar conclusions based on their bioeconomic model of a community in central Ethiopia, i.e. that by combining tree planting on marginal lands with technologies to promote more productive crop production, substantial increases in productivity and farm income were possible whilst reducing land degradation.…”

“…The findings of Okumu et al (2002), Holden et al (2005) and Woelcke et al (2006) concerning the impacts of multiple interventions suggest (but do not demonstrate) that there may be synergies among different policies if combined. Kuiper and Ruben (Chapter 17, this volume) make an important contribution to the literature on this issue by investigating the impacts of alternative policies or programmes separately and then jointly, and comparing the outcomes.…”

Sustainable Poverty Reduction in Less-Favoured Areas

View full text Add to dashboard Cite

This chapter discusses: (i) the strategic interactions between natural resource management options; (ii) farm-household livelihood strategies for welfare and risk; and (iii) the surrounding market and institutional conditions for simultaneously enabling poverty reduction and sustainable land use. The chapter starts with a definition of the main characteristics of less-favoured areas (LFAs), followed by an analysis of the interactions between poverty and resource degradation in LFAs. Hereafter, the biophysical, micro- and macroeconomic dimensions of LFA development are discussed in order to provide insight in the complex interfaces between agroecological options, household drivers for change and effective incentives for resource use adjustment. The chapter concludes with some major implications for policy and research concerning strategies for sustainable poverty reduction in less-favoured areas.
