“…Different tools to support such analysis and even the identification of causal relationships are available. Examples of such tools are the use of aggregated indices like the Environmental Index in Modified Stability Analysis, multiple linear regression or advanced statistical models(Hildebrand et al, 1993;Raman et al, 2011;Riley and Alexander, 1997).…”

“…The spatial aspect of these classifications was often either very broadly drawn, or implicit. The use of 'recommendation domains' within farming systems research sought to group farms, farmers, or households with similar characteristics or facing similar conditions, and for whom the same technical recommendations were likely to be appropriate (Collinson, 2000;Hildebrand, Singh, Bellows, Campbell, & Jama, 1993). Again, the spatial distribution of and/or spatial relations among and between recommendation domains was often of secondary importance.…”

While much has been said in recent years about the importance of engaging rural youth in sub-Saharan Africa's development, the factual data about how African youth currently engage in rural economies remain sparse. We use recent nationally representative household survey data from six countries to describe the patterns of such engagement. We find that young people participate in agriculture at similar rates to older people. However, participation in non-farm wage employment and business activity changes with age, peaking in the 30s. The likelihood of reporting no activity is greatest for people in their 20s. In more remote places, people leave school earlier and are less likely to engage in the non-farm sector, compared with people in more accessible places. We also find evidence that the non-farm economy is more diversified in relatively more accessible places, offering a larger set of options for economic engagement. We show that 'landscapes of opportunity' , defined by economic remoteness and agricultural potential, are an important way of assessing the choices available to young rural people. A key conclusion is that efforts to develop a 'youth lens' for rural development should not abandon the mainstays of rural investment strategies such as infrastructure, education, and agricultural R&D.

“…It makes sense therefore to use a local reference to evaluate response and suitability of treatments. An example of such a local reference is the environmental index (EI), which is applied in modified stability analysis to evaluate the performance of specific treatments in relation to a local reference (Hildebrand et al, 1993). For this evaluation, different criteria can be used depending on objective and perspective.…”

Application of nutrients is an important way to increase crop productivity. In our study area, Tigray, development agents recommend fertilizer application to boost productivity and counteract nutrient depletion. We analysed soil fertility from different perspectives, using responses and nutrient balances on the basis of on-farm experimentation. Three perspectives, embedded in the People-Planet-Profit framework and with different temporal and spatial scales and ownership, were considered. Taking a farmer perspective, we found no significant differences in response between recommended and current farmer practices. Taking an agronomist perspective, phosphorus seemed to limit productivity. It however also became obvious that closing nutrient balances at field scale to achieve sustainability is difficult. Only by using considerable amounts of manure and at the cost of productivity this can be achieved. From a long-term environmentalist perspective, the traditional agricultural system seems sustainable in combining mixed farming and relatively low yields. We conclude that depending on the perspective taken, different interventions will be appropriate. All perspectives however indicate that gradually strengthening the existing mixed farming system by using fertilizers, organic manure and legume fallows supports crop productivity while maintaining other aspects of sustainability such as food security and profitability. In line with this, our analysis of different perspectives suggests that in our study area, farmers will only consider transitions with low risk and this specifically should be addressed in proposing pathways of transition. In processes where stakeholders with different perspectives cooperate, it is important to be aware and make use of the possibilities of comparable multiperspective analyses.
