Enabling acceptance and use of ecological intensification options through engaging smallholder farmers in semi-arid rural Limpopo and Eastern Cape, South Africa

Ecological intensification is being promoted to address food security and environmental challenges. It has shown the potential to improve yields as well as adapt and mitigate the effects of climate variability and change. Despite the great potential, smallholder farmers continue to shun the latter. Apart from this, limited research has been conducted focussing on their acceptance and use in smallholder sub-Saharan African agricultural systems. In this study, a qualitative approach using the Unified Theory of Acceptance and Use of Technology (UTAUT) four constructs (performance, ease of use, social influence and enablers) was used to assess behavioral intention to accept and use ecological intensification options. A total of 97 smallholder farmers from diverse farm types in rural Limpopo and Eastern Cape, South Africa participated in focus group discussions to assess behavioral intention to accept and use ecological intensification options. Smallholder farmers revealed that they were exposed to a plethora of ecological intensification options. However, acceptance and utilization of these options were low, mainly due to lack of awareness, germplasm, and technical support. The four constructs of the UTAUT framework revealed locally relevant knowledge that must be considered for effective acceptance and use of ecological intensification options.

Developing pathways to improve smallholder agricultural productivity through ecological intensification technologies in semi-arid Limpopo, South Africa

Agriculture faces an enormous global challenge of feeding nine billion people by 2050. This means a comprehensive intensification of agriculture is required. Ecological intensification is gaining momentum as a clearly defined vision for increasing agriculture productivity and sustainability. How ecological intensification could be tailored to benefit smallholder farming systems in sub Saharan Africa (SSA) remains the major question. In this study, we develop pathways relying on ecological intensification technologies and suiting different farm types of smallholder agriculture. This study relies on multiyear engagements with agricultural experts and smallholder farmers in Ha Lambani, South Africa and leads to the identification of farmer groupings. We analyse 40 in-depth semi structured interviews with farmers which leads to the identification of farming patterns and constraints. We present how farming systems analysis of challenges and constraints helps to identify and link specific ecosystem services with suitable ecological intensification options. We conclude that the expert-based classification of farmers offered a more contextualized representation of farming system heterogeneity, where tailored ecological intensification technologies could play a major role in improving agricultural productivity. Beyond this community, it emphasizes the need to consider farmers type heterogeneity as a strong decision parameter for targeting ecological intensification

Background: With aging, many people develop Alzheimer’s disease or related dementias (ADRD) as well as chronic physical health problems. The consequent care needs can be complicated, with heavy demands on families, households and communities, especially in resource-constrained settings with limited formal care services. However, research on ADRD caregiving is largely limited to primary caregivers and high-income countries. Our objectives are to analyse in a rural setting in South Africa: (1) how extended households provide care to people with ADRD; and (2) how the health and wellbeing of all caregivers are affected by care roles. Methods: The study will take place at the Agincourt health and socio-demographic surveillance system site of the MRC/Wits Rural Public Health and Health Transitions Research Unit in Mpumalanga Province, northeast South Africa. We will recruit 100 index individuals predicted to currently have ADRD or cognitive impairment using data from a recent dementia survey. Quantitative surveys will be conducted with each index person’s nominated primary caregiver, all other household members aged over 12, and caregiving non-resident kin and non-kin to determine how care and health are patterned across household networks. Qualitative data will be generated through participant observation and in-depth interviews with caregivers, select community health workers and key informants. Combining epidemiological, demographic and anthropological methods, we will build a rich picture of households of people with ADRD, focused on caregiving demands and capacity, and of caregiving’s effects on health. Discussion: Our goal is to identify ways to mitigate the negative impacts of long-term informal caregiving for ADRD when formal supports are largely absent. We expect our findings to inform the development of locally relevant and community-oriented interventions to improve the health of caregivers and recipients, with implications for other resource-constrained settings in both higher- and lower-income countries

Independent and combined effects of improved water, sanitation, and hygiene, and improved complementary feeding, on child stunting and anaemia in rural Zimbabwe: a cluster-randomised trial.

BACKGROUND: Child stunting reduces survival and impairs neurodevelopment. We tested the independent and combined effects of improved water, sanitation, and hygiene (WASH), and improved infant and young child feeding (IYCF) on stunting and anaemia in in Zimbabwe. METHODS: We did a cluster-randomised, community-based, 2 × 2 factorial trial in two rural districts in Zimbabwe. Clusters were defined as the catchment area of between one and four village health workers employed by the Zimbabwe Ministry of Health and Child Care. Women were eligible for inclusion if they permanently lived in clusters and were confirmed pregnant. Clusters were randomly assigned (1:1:1:1) to standard of care (52 clusters), IYCF (20 g of a small-quantity lipid-based nutrient supplement per day from age 6 to 18 months plus complementary feeding counselling; 53 clusters), WASH (construction of a ventilated improved pit latrine, provision of two handwashing stations, liquid soap, chlorine, and play space plus hygiene counselling; 53 clusters), or IYCF plus WASH (53 clusters). A constrained randomisation technique was used to achieve balance across the groups for 14 variables related to geography, demography, water access, and community-level sanitation coverage. Masking of participants and fieldworkers was not possible. The primary outcomes were infant length-for-age Z score and haemoglobin concentrations at 18 months of age among children born to mothers who were HIV negative during pregnancy. These outcomes were analysed in the intention-to-treat population. We estimated the effects of the interventions by comparing the two IYCF groups with the two non-IYCF groups and the two WASH groups with the two non-WASH groups, except for outcomes that had an important statistical interaction between the interventions. This trial is registered with ClinicalTrials.gov, number NCT01824940. FINDINGS: Between Nov 22, 2012, and March 27, 2015, 5280 pregnant women were enrolled from 211 clusters. 3686 children born to HIV-negative mothers were assessed at age 18 months (884 in the standard of care group from 52 clusters, 893 in the IYCF group from 53 clusters, 918 in the WASH group from 53 clusters, and 991 in the IYCF plus WASH group from 51 clusters). In the IYCF intervention groups, the mean length-for-age Z score was 0·16 (95% CI 0·08-0·23) higher and the mean haemoglobin concentration was 2·03 g/L (1·28-2·79) higher than those in the non-IYCF intervention groups. The IYCF intervention reduced the number of stunted children from 620 (35%) of 1792 to 514 (27%) of 1879, and the number of children with anaemia from 245 (13·9%) of 1759 to 193 (10·5%) of 1845. The WASH intervention had no effect on either primary outcome. Neither intervention reduced the prevalence of diarrhoea at 12 or 18 months. No trial-related serious adverse events, and only three trial-related adverse events, were reported. INTERPRETATION: Household-level elementary WASH interventions implemented in rural areas in low-income countries are unlikely to reduce stunting or anaemia and might not reduce diarrhoea. Implementation of these WASH interventions in combination with IYCF interventions is unlikely to reduce stunting or anaemia more than implementation of IYCF alone.

Assessing the value of ecological intensification in improving smallholder farmers' food security and rural livelihoods in a changing climate

Attaining the twin goals of food security and environmental sustainability has spurred focus on two main models of production, sustainable and ecological intensification as means to produce more food per unit land area while simultaneously ensuring environmental sustainability. A better understanding of their suitability and applicability in diverse and heterogeneous biophysical and socio-economic situations of smallholder farmers is still largely needed in sub Saharan Africa (SSA). This study aimed to assess the value of ecological intensification of agriculture to improve food production systems and environmental sustainability in smallholder farming systems in the face of climate variability and change. This study uses two rural districts in South Africa namely Vhembe and Amathole from Limpopo and the Eastern Cape provinces respectively as a case study to explore how ecological intensification can help smallholder farmers. The study explored the fit and potential of ecological intensification in smallholder agricultural systems and steps to be taken to support its implementation and development. The study then uses the Design, Explain, Evaluate and Design (DEED) approach to develops pathways relying on ecological intensification technologies and suiting different farm types of smallholder agriculture. Two iterations of the DEED approach were performed that enabled characterisation of farmers and farming systems and farming systems analysis of challenges and constraints that helped to identify and link specific ecosystem services with suitable ecological intensification options. Furthermore, the study assesses the acceptance and use of ecological intensification options in the heterogeneous biophysical and socioeconomic context of smallholder farmers through the Unified Theory of Acceptance and Use of Technology (UTAUT) framework. Besides the productivity potential, the study sheds light on locally relevant knowledge that must be considered to enable acceptance and use of ecological intensification options. I finally explored the potential of ecological intensification to meet the goals of improving productivity and environmental sustainability concurrently through a biophysical modelling approach encompassing a farm typology, a crop model and a farm focussed greenhouse gas calculator. The results provide valuable insights into the ongoing debate on how to intensify smallholder cropping systems. More specifically, the results show that the integration of agroecological approaches in smallholder cropping systems has the potential to deliver ecological intensification in which productivity is improved and ecosystem services such as climate change regulation through reduction of GHG emissions from cropping systems are simultaneously increased to enhance environmental sustainability. Overall, the study articulates various pieces of evidence to show that ecological intensification is suitable, applicable and, can attain the twin objectives of improving food production systems concurrently ensuring environmental sustainability, in heterogeneous smallholder agricultural systems in SSA. This contribution raises the need for further attention to be given to smallholder agricultural intensification policies and research or to agricultural intensification to explicitly consider the heterogeneous biophysical and socioeconomic circumstances of smallholder farmers in SSA
