Effectiveness of online counselling during COVID-19 in Zambia. A client and therapists perspective.

Population-based studies have shown that a growing number of counsellors have been providing counselling via the Internet. There are mixed findings regarding the effectiveness of online counselling compared to traditional face-to-face counselling and other modalities. During the COVID-19 outbreak, online counselling services were advanced as the only safe means of attending to mental health conditions, especially during the lockdowns. However, the effectiveness of online counselling remains unclear, especially in developing countries with low digital literacy and poor Internet connectivity. This study's main purpose was to investigate and determine the clients' and therapists' perspectives on the effectiveness of online counselling during the pandemic based on the level of preparedness, mode of delivery, and challenges faced. The study used mixed methods employing a parallel convergent design and collected data from 284 participants (44 therapists and 240 counselling clients). The study found that therapists were not prepared to offer online counselling services, but were compelled by high demands for counselling services from clients during the pandemic. Both clients and therapists cited the cost of data bundles to connect to the Internet as a major barrier. Furthermore, both clients and therapists indicated that the most effective platform was video conferencing. The findings also show that therapists observed slowed progress in the client's recovery due to clients missing sessions. Logistic regression results on factors associated with preparedness and positive perception of online counselling showed that older therapists and lay counsellors were less likely to be prepared and evaluate sessions as less effective, respectively. Living in Lusaka (the capital) was associated with higher odds of perceiving online counselling as effective. Client results showed that older clients had lower odds of being prepared, and the counsellor being prepared increased the odds of the online counselling being perceived as effective. The researchers conclude that online counselling, in the context of a developing country, is ineffective because of the cost of Internet connection, the multiplicity of information communication technology (ICT) channels, low digital literacy, and lack of knowledge or experience using these platforms.

Pollinator-dependent crops significantly contribute to diets and reduce household nutrient deficiencies in sub-Saharan Africa.

Recent literature highlights the potential of animal pollinator-dependent (PD) crops in enhancing food and nutrition security, although there is a lack of detailed household-level estimates. In this study, we investigate the nutrient composition, productivity, and contribution of PD and pollinator-independent (PI) crops to household nutrition in four sub-Saharan African (SSA) countries. We also evaluate the impact of reallocating resources from PI crops to PD crops on nutrient deficiencies, utilizing nationally representative panel data from three waves and over 30,000 household-year observations. Our findings reveal that PD crops exhibit higher micronutrient content per unit, albeit with lower macronutrient content compared to PI crops. PI crops have higher yield of calories per hectare while PD crops have higher vitamin A yield per hectare. However, protein and iron yield for PD and PI crops varies across countries. PI crops predominantly contribute to macronutrients and iron, while PD crops significantly contribute to vitamin A production. Our econometric results demonstrate that increasing the cultivation of PD crops relative to PI crops reduces the prevalence of nutrient deficiencies and increases crop income without compromising macronutrients production. This suggests that greater investment in PD crop production can be an integral approach to achieving nutrition security in SSA.

The economic performance of mango integrated pest management practices at different scales of production.

Integrated pest management (IPM) strategies are being promoted to suppress tephritid fruit fly infestation and reduce economic damage in mango production. However, research on their economic performance across different mango production scales (measured by the number of mango trees) is limited. This study estimated the economic benefits of IPM practices (parasitoids, orchard sanitation, food bait, biopesticides, male annihilation technique, and their combinations) in Kenya's small-, medium-, and large-scale mango production systems. We used the value-cost ratio (VCR) and net present value methods to estimate the heterogeneous economic performance of IPM practices using data from two unique farm surveys. On average, all IPM practices were profitable across various production scales. However, we found that these practices were more profitable for medium-scale farmers than for small- and large-scale farmers. The results show that farmers need a minimum of 9-17 trees, depending on the practice used, to break even and that there are little to no economic benefits to using IPM practices for farmers with more than 320 mango trees. The male annihilation technique was the most profitable practice, with a VCR of 36, and consequentially, the most adopted practice across all scales of production. Overall, we found significant heterogeneity in the profitability of IPM practices across different scales of production. The reason for the lack of profitability of IPM on large-scale farms remains unclear and warrants further investigation.

Striving to be resilient: the role of crop-poultry integrated system as a climate change adaptation strategy in semiarid eastern Kenya.

Climate change continues to pose significant challenges to food security and livelihoods of smallholder farmers specifically in semi-arid regions. One approach that holds prospects for climate risk management is climate-smart agriculture (CSA). CSA has concentrated on crop practices with little attention to livestock especially indigenous (village) chickens as a potential practice that can be combined with crop agriculture. This study considers the adoption of three CSA practices: improved maize seeds (IS), soil management (SM), indigenous chicken (IC) enterprise and their various combinations. Using survey data collected from 300 farming households in semiarid Kenya, we estimate the impact of integrated crop-poultry system adoption on food security and farm income using multinomial endogenous treatment effect models. Robustness checks are conducted using alternative identification strategies. Results show that, generally, the adoption of IS, SM, IC and their combinations reduces the number of months without enough food and increases farm income. When we consider the magnitude of the impacts, interesting results emerge when a combination of the CSA practices are considered. The highest impact is observed with the joint adoption of SM & IC and IS &IC. Broadly, the empirical findings suggest that integrated systems (in our case crop-poultry integration), deserve both policy and research attention as they provide synergistic benefits that improve climate resilience and household welfare.

The potential economic benefits of insect-based feed in Uganda.

Black soldier fly farming is gaining traction globally as a strategy for recycling organic waste into high-quality proteins and fat for feed and organic fertilizer for crop production. The support of governments in East Africa to integrate insect meal in livestock feed has opened opportunities for commercializing insect products. Understanding the potential value of Black soldier fly larvae meal (BSFLM) is paramount to inform policies and practices to promote insect farming and insect-based feed for livestock production. This paper uses the economic surplus method to generate evidence on the potential socioeconomic impact of replacing conventional soybean and fish meal protein sources with insect-based feed (IBF), BSFLM, in Uganda. Results indicate that substitution of IBF for existing protein sources will generate net economic benefits of USD 0.73 billion in 20 years (0.037 billion per year). The benefit-cost ratio is estimated at 28:1, and the internal rate of return is 138%, indicating that the insect-based animal feed industry is a profitable investment. Even in the worst-case scenario, when the replacement rate of IBF and its economic benefits are reduced by half, the benefit-cost ratio remains high (8:1). The estimated economic benefit can lift about 4.53 million people above the poverty line in the country. It can also create about 1,252─563,302 new jobs per annum, depending on the substitution rate of conventional protein feeds with IBF (0.1%─45%). Uganda has the potential to produce from about 3,244 tons to 1.5 million tons of IBF. Similarly, using the same replacement rates, the country can produce about 695─312,678 tons of NPK fertilizer from biowaste recycling. About 0.09-41 million tons of biowaste could be recycled, depending on the replacement rate of conventional feed sources with IBF. Our results justify that investing in the insect feed value chain can contribute to Uganda's economic, social, and environmental sustainability.

The effectiveness of national biodiversity investments to protect the wealth of nature.

Finance will be among the priority concerns when the United Nations Convention on Biological Diversity launches the post-2020 framework for global biodiversity conservation (Global Biodiversity Framework) in 2021. The Biodiversity Finance Initiative provides a means for countries to account systematically for their biodiversity expenditures. A sample of 30 countries facilitated the construction of a panel to better understand the effectiveness of public biodiversity investments. Overall, the results show a positive trend in national public biodiversity investments and that larger economies invest more in biodiversity in gross magnitude and as a percentage of gross domestic product (GDP) (0.30% of GDP among wealthy countries versus 0.29%) and of national budgets (1.78% versus 1.14%). Controlling for GDP, wealthier countries invest proportionately less than less wealthy countries. The relationship between GDP and public biodiversity expenditure is an inverted-U curve. All biodiversity-related variables (threatened species, protected area and the presence of a hotspot) were positively correlated with public biodiversity investments. Funds allocated to biodiversity are associated with a reduction in the number of threatened species and the rate of biodiversity loss of about 1% per year. Each US$1 billion investment in biodiversity is associated with an annual reduction in the proportion of threatened to total species of about 0.57%. Population growth is associated with lower financial support for biodiversity and an increase in the proportion of threatened to total species in a country.
