Fertiliser credit and agroecological use of organic soil amendments in northern Ghana
Contemporary African agricultural policy embodies the African Green Revolution’s drive towards modernisation and commercialisation. Agroecologists have criticised this movement on ecological, social and political grounds. Northern Ghanaian fertiliser credit schemes provide a good example through which these critiques can be examined in a context where agricultural policy reflects the African Green Revolution’s ideals. This study aimed to determine the relationship of such credit schemes to farmers’ use of organic amendments, elucidate other factors related to organic amendment use, and comment on the relevance of this modernisation policy and its relationship to agroecology. A first research phase employed semi-structured key informant interviews. Qualitative data from these informed construction of a semi-structured questionnaire that was used in a survey of 205 farmers. Multistage sampling purposively identified five villages and selected farmers within who had joined government and donor-funded fertiliser credit schemes. The use of organic and inorganic amendments was compared to that of peers who had not taken part in such schemes. Quantitative data were used in binomial logistic regression, inferential and descriptive statistics. Qualitative data were content analysed. Credit group membership was associated with higher fertiliser application and yield, but had little influence on the extent of commercialisation. Farmers who applied organic amendments were 40% less likely to belong to a fertiliser credit scheme than not, indicating substitution between organic and inorganic fertilisers. Organic amendments were 40% more likely to be applied to compound farms than outfields and six times more likely to be applied by household heads than other household members. However, household heads also preferentially joined credit groups. This was part of an agroecological soil fertility management strategy. Household heads appreciated the soil moisture retention properties of organic amendments, and applied them to compound farms to reduce risk to their household food supply in a semi-arid environment. They simultaneously accessed fertiliser to enhance this household provisioning strategy. They appreciated the increased yields this achieved, yet complained that the repayment terms of credit schemes were unfair, fertiliser did not enhance yields in dry conditions and fertilisers were supplied late. Farmers’ use of credited fertiliser alongside their existing agroecological strategy is helpful to the extent that it raises yields, yet is problematic in that it conflicts with risk-reduction strategies based on organics. There is some potential for modernised and agroecological management paradigms to coexist. For fertiliser credit to play a role in this, schemes must use fairer repayment terms and involve a focus on simultaneous use of organic amendments.Keywords: Agroecology, compost, Ghana, fertiliser credit, Soil Fertility Management, maiz
The Roles of Dimensionality, Canopies and Complexity in Ecosystem Monitoring
Canopies are common among autotrophs, increasing their access to light and thereby increasing competitive abilities. If viewed from above canopies may conceal objects beneath them creating a ‘canopy effect’. Due to complexities in collecting 3-dimensional data, most ecosystem monitoring programmes reduce dimensionality when sampling, resorting to planar views. The resultant ‘canopy effects’ may bias data interpretation, particularly following disturbances. Canopy effects are especially relevant on coral reefs where coral cover is often used to evaluate and communicate ecosystem health. We show that canopies hide benthic components including massive corals and algal turfs, and as planar views are almost ubiquitously used to monitor disturbances, the loss of vulnerable canopy-forming corals may bias findings by presenting pre-existing benthic components as an altered system. Our reliance on planar views in monitoring ecosystems, especially coral cover on reefs, needs to be reassessed if we are to better understand the ecological consequences of ever more frequent disturbances

Agricultural commercialisation in Africa, COVID-19 and social difference [weblog article, 15 November 2021]
African policymaking has turned to agricultural commercialisation as an engine of growth in the 21st century. But the effects have not been the same for everyone, entrenching long-term social difference based on gender, wealth, age and generation, ethnicity and citizenship. Social differentiation within commercial agriculture is shaped by power dynamics and the distribution of benefits between elites, and their relationship with the formal and informal institutions that underpin political systems. This idea of a ‘political settlement’ in the way that power is exercised between groups, often to avoid conflict or to give preferential access to a specific resource, gives different groups of people different standing within agricultural value chains. COVID-19 as a type of shock also shapes political settlements and the resilience of different actors in their response to the pandemic. It can also reinforce pre-existing trends in social differentiation. APRA’s research showed how this has happened across Ethiopia, Ghana, Malawi, Nigeria, Tanzania, and Zimbabwe, and APRA Working Paper 69 presents the research findings
COVID-19 and social differentiation in African agriculture
This brief presents a summary of key findings from a multi-country study of social differentiation in African agricultural value chains in the context of COVID-19. It aims to understand how trends in the politics and participation of different actors in agriculture have contributed to patterns of social differentiation, and how these patterns have interacted with the shock of COVID-19. It brings attention both to the implications of political decision-making and the effects of the pandemic on value chain structures and those working within the sector
Land tenure, food security, gender and urbanization in Northern Ghana
Links between land tenure and food and nutritional insecurity are receiving increased attention. Nevertheless,
urban and periurban dwellers face challenges in accessing land to produce food for subsistence and sale. An
ethnographic study and food and nutrition insecurity survey were conducted between October 2013 and
November 2014 in Tamale, Northern Region of Ghana, to explore the dynamic and recursive links between land
access, food access and the ability to maintain resources to meet long-term needs. Results showed that infra structural development and agriculture compete for land. The shortage of land for agricultural purposes was
pronounced in urban areas (20%) than in periurban areas (1.3%) and rural areas (0%). Food insecure households
were more likely to name a lack of land than anything else as the primary reason for their inability to grow crops
(Fisher’s exact probability = 0.040). Urban and periurban dwellers cope with the constraints posed in the
communal tenure system by using strategies such as urban–periurban-rural migrant farming and buffer zone
cultivation. The role of women in providing nutritious soups is especially important, and they use various
mechanisms to circumvent their lack of access to land and provide food for the household. Political, economic
and cultural elements thus interact to constitute the link between land and food
