Mitigating the effects of drought on cattle production in communal rangelands of Zimbabwe

Forage yield and nutritive value of Desho grass (Pennisetum glaucifolium Trin.) as affected by cutting heights in the central highlands of Ethiopia

Desho grass (Pennisetum glaucifolium Trin) an important fodder grass. However, information on its production is lacking. This study was carried out to evaluate the forage dry matter yield and nutritive value of Desho grass harvested at different cutting heights (CH), under rain-fed conditions in two different sites in central highlands of Ethiopia for two years. The treatments (T1-T8) were: 50, 60, 70, 80, 90, 100, 110, and 120 cm cutting heights, distributed in a randomized complete block design with three replications. The root splits of the grass were planted in a 3 m × 4 m (12 m2) plot size with 0.5 m × 0.25 m inter and intra-row spacing. In the two locations, over the years, significant differences were observed among cutting heights. The interaction of cutting heights by locations, and location by years were also significant. The interaction among cutting height, location, and year was insignificant. The highest (number of leaves per plant) NLPP was attained as the plant height advance, while the number of tillers per plant (NTPP) showed non-significant differene in different treatments. The dry matter yield (DMY) increased linearly with an increase in CH (ranging from 12.2 to 20.1 t ha-1 at Holetta, and 4.2 to 11.4 t ha-1at Kulumsa). The grass's ash and crude protein (CP) contents decreased as the cutting height increased. An increase in CH increased the fiber content Neutral detergent fiber (NDF), acid detergent fiber (ADF), and Acid detergent lignin (ADL), resulting decrease in in-vitro dry matter digestibility (IVDMD). We recommend that desho grass be managed at 80-90 cm height resulting in optimum dry matter yield and nutritive value for use in smallholder farmers and market-oriented livestock producers of the central highlands of Ethiopia and major growing areas.

Factors influencing the integration of indigenous and conventional knowledge of water security for livestock

Farmers have developed indigenous knowledge (IK) on predictive and adaptation strategies to sustain water security. The objective of the study was to determine factors that influence the integration of IK and conventional knowledge (CK) to ensure water security for livestock. Focus group discussions and semi-structured interviews were used to gather data. Farmers in Musina and uMhlabuyalingana use IK indicators to predict rain for water security. Farmers in uMhlabuyalingana predicted rain using wind movement more than their counterparts in Musina (P < 0.05). Taboos were used (P > 0.05) in both Musina and uMhlabuyalingana to ensure water security. Cultural prohibitions were used more in uMhlabuyalingana to cope with water shortages than in Musina (P < 0.05). Boreholes, home taps and municipal water were not properly maintained (P > 0.05). Socio-economic factors had greater influence on the integration of IK and CK. Males were 2.24 times likely to support integration of IK and CK compared to women. Adults were 7.1 times likely to support integration of IK and CK compared to those that were younger. Farmers were open to the integration of conventional and indigenous knowledge to ensure water security. Promoting the integration of IK and CK enables stakeholders to gain access to valuable information which can, in turn, promote sustainable community development.

Assessing Vulnerability to Climate Change in Smallholder Irrigation Schemes of Zimbabwe

Globally, climate change poses enormous threats to the livelihoods of rural communities in arid and semi-arid regions. Assessing the extent of vulnerability is critical to identify climate hot spots and develop appropriate adaptation policies and strategies. This paper uses the Livelihood Vulnerability Index (LVI) and the Livelihood Vulnerability Index—Intergovernmental Panel on Climate Change (LVI-IPCC) to compare vulnerability to climate change in the Exchange, Insukamini, and Ruchanyu smallholder irrigation schemes (SISs) in the Midlands Province of Zimbabwe. A questionnaire was used to collect data from a sample of 317 randomly selected households. Results show higher exposure and sensitivity to climate change in the Insukamini irrigation scheme despite the higher adaptive capacity. Both LVI and LVI-IPCC show that households in Insukamini irrigation scheme are more vulnerable to climate change than in Exchange and Ruchanyu irrigation schemes, attributed to water insecurity, poor social networks, and natural disasters and climate variability. The study recommends that development and investment in Insukamini and Ruchanyu should prioritize improving social networks while Exchange should primarily focus on improving livelihood strategies. Using the LVI-IPCC framework is a key methodology for understanding the vulnerability of communities in SISs and identifying areas that need prime development and investment. These results have implications on implementing investments and livelihood policies in SISs of Zimbabwe.

Forced displacement: critical lessons in the protracted aftermath of a flood disaster

Forced displacement and resettlement is a pervasive challenge being contemplated across the social sciences. Scholarly literature, however, often fails to engage complexities of power in understanding socio-environmental interactions in resettlement processes. Addressing Zimbabwe's Tokwe-Mukosi flood disaster resettlement, we explore hegemonic uses of state power during the pre- and post-flood induced resettlement processes. We examine how state power exercised through local government, financial, and security institutions impacts community vulnerabilities during forced resettlement processes, while furthering capitalist agendas, drawing insights from analysing narratives between 2010 and 2021. Concerns abound that multiple ministries, the police, and the army undermined displaced people's resilience, including through inadequate compensation, with state institutions neglecting displaced communities during encampment by inadequately meeting physical security, health, educational, and livestock production needs. We explore how forcibly resettling encamped households to a disputed location is not only an ongoing perceived injustice regionally but also a continuing reference point in resettlement discussions countrywide, reflecting concerns that land use and economic reconfigurations in resettlement can undermine subsistence livelihoods while privileging certain values and interests over others. Policy lessons highlight the need for reviewing disaster management legislation, developing compensation guidelines and reviewing encampment practices. Analytically, lessons point to how state power may be studied in relation to perspectives on the destruction of flood survivors' connections to place, people and livelihoods, underscoring the critical need for theorising the relationships between power dynamics and diverse experiences around displacement.

Harnessing of Social Capital as a Determinant for Climate Change Adaptation in Mazungunye Communal Lands in Bikita, Zimbabwe

The livelihoods of rural people have been plagued by the precarious impacts of climate change-related disasters manifesting through floods, heat waves, droughts, cyclones, and erratic temperatures. However, they have not remained passive victims to these impacts. In light of this, rural people are on record of employing a plethora of adaptation strategies to cushion their livelihoods from climate change impacts. In this vew, the role of social capital as a determinant of climate change adaptation is underexplored. Little attention has been paid to how social capital fostered through trust and cooperation amongst rural households and communities is essential for climate change adaptation. This study explored how people in Mazungunye communal lands are embracing social capital to adapt to climate change impacts. The researchers adopted a qualitative research approach guided by the descriptive research design. The population of the study was gathered through simple random and purposive sampling techniques. Accordingly, the population sample consisted of 25 research participants drawn from members of the community following the simple random and purposive sampling techniques. In-depth individual interviews and focus group discussions were used to collect data. Data were analysed through the Thematic Content Analysis. This study established that different forms of social capital are being embraced by the community members to withstand the effects of climate change. These include village savings clubs (fushai), chief's granary (Zunde raMambo), collective field work (nhimbe), and destocking of livestock (kuronzera) strategies. These strategies illustrate community reliance on indigenous knowledge adaptation strategies as a community response to impacts of climate change on their livelihoods.
