    An operational scale, efficacy tests of the optimal dose of the bioinsecticide Bb11 (Bba5653), including observation data on useful non-targets. Specifically, participatory trials with vegetable growers were carried out, at the Tuba Irrigation Site in the Ga West District of the Greater Accra Region of Ghana, to demonstrate the effectiveness of the biological insecticide Bba5653 under field conditions in Ghana. The demonstration also included the evaluation of BSF frass in cabbage production systems.

    Small-scale fisheries (SSF) account for much of the global fish catch, but data to assess them often do not exist, impeding assessments of their historical dynamics and status. Here, we propose an approach to assess 'data-less' SSF using local knowledge to produce data, life history theory to describe their historical multispecies dynamics, and length-based reference points to evaluate stock status. We demonstrate use of this approach in three data-less SSFs of the Congo Basin.

    The importance of land restoration has garnered increasing attention on the global stage through large-scale initiatives such as the Bonn Challenge. However, policies and strategies are often gender-blind and designed in compliance with entrenched
    social hierarchies, exacerbating pre-existing social inequalities that affect restoration initiatives. The challenge of developing gender-responsive policies and initiatives is accentuated by a persistent lack of sex-disaggregated data concerning men's and

    Transforming global food systems to promote food and nutritional security can help alleviate both poverty and ill-health, and support sustainable development. Such transformations need to be tailored and sensitive to the vulnerabilities and needs of marginalized communities yet are hindered by knowledge gaps. In particular, the food and nutrition security needs of the most vulnerable are often poorly understood, as are the policy frameworks and resource requirements associated with meeting their needs.

    Although Ghana is a leading global cocoa producer, its production and yield have experienced declines in recent years due to various factors, including long-term climate change such as increasing temperatures and changing rainfall patterns, as well as drought events. With the increasing exposure of cocoa-producing regions to extreme weather events, the vulnerability of cocoa production is also expected to rise. Supplemental irrigation for cocoa farmers has emerged as a viable adaptation strategy to ensure a consistent water supply and enhance yield.

    This paper identifies the challenges, aspirations, and entry points for greater participation and empowerment of youth and women in the fast-growing aquaculture value chain in Ghana. Data was collected from three survey rounds of 400 fish farmers; 32 key informants’ interviews; and 5 FGDs with female-only, femaleyouth-only, and male-youth-only groups. Four study highlights are as follows. First, the study shows that respondents all indicated they wanted to continue or start aquaculture and expand to other stages of the value chain (hatchery, feed formulation, processing).

    Tanzania is endowed with a diversity of ecosystems, huge number of cattle farming and available arable land. However, the productivity per cow is still very low due various reasons. This study used data from African Asian Dairy Genetic Gains (AADGG) database collected over a period of 2016 to 2023 in combination with mini survey of cost of production done in twenty-four (24) Local Government Authorities (LGAs) to determines factors that influence total factor productivity in the small-scale dairy farm in selected district in Tanzania.

    Tanzania smallholder dairy is constrained by lack of access to high yielding and locally adapted genetics. To improved dairy genetics Artificial insemination (AI) is the best tool to use. However, uptake of AI services is variable across the country. Information on individual animals born through AI and their performance levels within the different environments are lacking, hence difficult to evaluate the performance of the progeny born from AI bulls and to select best genetics.

    Worldwide, cell phones are used by 5.4 billion people. They are becoming increasingly prevalent in the rural areas of low- and middle-income countries (LMICs), providing smallholder farmers with access to agricultural markets. If they reduce information asymmetries between women and men farmers, they can also contribute to closing the gender gap in agricultural productivity. So far, however, digital innovations have had limited success in transforming agricultural systems. This may be due, in part, to the gender gap in cell-phone use.
