    Men and women interact with water resources and landscapes in different ways, and there are frequent criticisms that little research is undertaken across disciplines to address this issue. Biophysical scientists in particular struggle with how to integrate “gendered” water uses into models that are necessarily based on prevailing laws and equations that describe the movement of water through the hydrological cycle, independent of social constructs.

    Safe water is widely recognized as both a fundamental human need and a key input into economic activity. Across the developing world, the typical approach to addressing these needs is to segregate supplies of water for domestic use from water for large-scale agricultural production. In that arrangement, the goal of domestic water supply is to provide small amounts of clean safe water for direct consumption, cleaning, bathing and sanitation, while the goal of agricultural water supply is to provide large amounts of lower quality water for irrigated agriculture.

    Eritrea

    Hanfets is a popular mixture of wheat and barley grown in the highlands of Eritrea and Tigray (Northern Ethiopia). In this study, we tested 16 experimental hanfets constituting all possible combinations of four barley landraces and four wheat (two landraces and two varieties) at three locations in Eritrea for 3 years during which farmers (both men and women) made selections of suitable hanfets. Across locations and years, the grain yield of hanfets on average was similar to that of the pure barley but significantly higher than that of wheat.

    Social learning plays key roles in sustainable natural resource management; however, studies on its role show mixed results. Even though most current studies highlight positive outcomes, there are also negative effects of social learning with respect to natural resource management. This paper explores the influence of social learning outcomes on the adoption of soil conservation practices in Amba Zuria, Ethiopia. Data were collected through semi-structured interviews, group discussions and in workshops.

    Previous studies in drylands have shown that while gender roles are becoming more flexible, privatization and formalization of land tenure tends to marginalize women in drylands while environmental degradation leads to differential changes in gender workload. Chepareria, a ward in West Pokot County, has undergone the above-mentioned tenure and environmental changes and is nowadays dominated by private enclosures as a land management approach.

    The study assessed poverty in rural areas of Ogun State, Nigeria through the food energy (calorie) intake approach. A sample of 60 households (comprising of 346 members) were selected using a multistage sampling technique and were interviewed with the aid of well‐structured questionnaire. Data were analysed using nutrient estimation techniques, cost of calorie method and poverty index. The estimated food poverty line was 64.72 naira.

    Goats account for about 30% of Africa’s ruminant livestock and produce about 17 and 12% of its meat and milk, respectively. Sub-Saharan Africa (SSA) accounts for over 60% of the total goat population in Africa, with an estimated 147 million goats representing about 80 indigenous breeds or strains distributed across all agro-ecological zones and ruminant livestock production systems. Goats are particularly important in marginal agricultural land areas, especially in arid and semi-arid areas, which together hold 64% of the goat population.

    India has a maximum area (21.6%) under cashew nut and is the third largest producer (17.3%) of raw nuts in the world. The country is the second largest exporter, accounting for 34% of the world’s export of cashew kernels having a comparative advantage in production and processing on account of its cheap and skilled labour force. The yields in India are poor at 860 kg/ha as compared to 4,125 kg/ha in Vietnam and 2,000 kg/ha in Nigeria.
