STAKEHOLDER INVOLVEMENT DURING PROJECT INITIATION: A SUSTAINABILITY FACTOR OF SMALLHOLDER DONOR-FUNDED IRRIGATION PROJECTS IN ZVIMBA DISTRICT, ZIMBABWE
Authors: Matsika Oliver , Marara Osward , F. Chinamasa Emmanuel
Published: September 2022

The purpose of this study was to examine whether the involvement of stakeholders during initiation of donor-funded smallholder irrigation projects in Zvimba district, Zimbabwe, was a critical sustainability factor. Donor-funded smallholder irrigation projects investments enhance water security for agricultural production and improve peasant farmers’ livelihoods in the face of climate change induced risks. While these donor-funded smallholder irrigation investments have historically empowered local communities, ensured food security and contributed to economic growth, we have an incomplete understanding of why they collapse after the withdrawal of the donors. This paper addresses this gap by adopting the pragmatism philosophy which prompted the use of whatever works to explore how involvement of stakeholders during initiation of irrigation investments influences its sustainability. To do so, stratified and purposive sampling techniques were used to select a population of 360 people who included donor-funded irrigation project beneficiaries, community, local leaders and Agritex officers for a Zvimba district case study. The results advance that collapses of investments are consequences of non-involvement of beneficiaries in initiation of donor-funded smallholder irrigation projects. The findings highlight that in the context of irrigation projects in Zvimba district, donors, government officials and political actors were the only participants during needs assessment, stakeholder identification and project designing phases. Project beneficiaries from the communities and suppliers of irrigation equipments and inputs only came on board during the project construction phases. While findings remain contextual to the Zvimba district study area, the study concludes that non-involvement of beneficiaries, inputs suppliers, buyers, interest groups in the initiation process of the donor-funded irrigation project was a critical sustainability factor. In that context, the study recommended the adoption of a participatory donor-funded smallholder irrigation project initiation model, which calls for the involvement of all stakeholders for the entire irrigation project development life cycle.

Published: September 2022

Rubidium sulfate crystal is an inorganic material and it is doped with an organic material viz. L-leucine to improve the various properties of the host crystal. L-leucine doped rubidium sulfate (LLRS) crystals have been grown by solution method. LLRS crystals have been harvested after the growth period of 30 days. The grown LLRS crystal is observed to be crystallizing in orthorhombic structure by single crystal XRD studies. Mechanical studies were carried out to find the mechanical strength and other parameters. Dielectric studies of L-leucine doped rubidium sulfate crystals were carried out to evaluate dielectric constant, dielectric loss and activation energy. UV-visible-NIR spectral studies were done in the wavelength range 200-1100 nm and linear optical properties like transmittance, absorption coefficient and extinction coefficient of samples have been evaluated. Second order Non Linear Optical (NLO) studies of the grown crystal of LLRS were carried out by Kurtz-Perry technique. The fundamental absorption was noted at 280 nm and at 278 nm for undoped and L-leucine doped rubidium sulphate crystals respectively. The optical band gap of LLRS crystal was found to be slightly more than that of undoped rubidium sulphate crystal. The SHG efficiency of LLRS crystal is observed to be 0.61 times that of the reference KDP sample.

Authors: Thakur Niharika
Published: September 2022

Nigella sativa L (Ranunculaceae family) or commonly known as black cumin has long been used as a phytomedicine for antidiarrhea, appetite enhancer, diuretic, antibacterial, analgesic, anthelmintic, various skin diseases, anti-inflammatory, back pain, hemiplegia (paralysis of the hands or feet) and rheumatism. The objective of this study was to investigate pharmacognostical, phytochemical features, antioxidant activity and abortifacient effects of ethanol and aqueous extracts of Nigella sativa seed by using DPPH assay method and pregnancy maintenance model respectively. The different pharmacognostical parameters were evaluated as per standard protocols with some modifications. The preliminary phytochemical studies were performed with various reagents and chemicals on seed extracts in order to determine the various secondary metabolites. The ethanol and aqueous extracts of Nigella sativa seeds were screened for in-vitro antioxidant activity by oxygen radical scavenging such as 1, 1-diphenyl-2- picrylhydrazyl (DPPH) method. Abortifacient activity was studied in rats at 400 mg/kg doses administered orally from 8thto 20thdayof pregnancy. Rats were laparotomised on 21st day. Weight of fetus, percentage of abortion and thelive and dead fetuses were observed in both horns of the uterus. Pharmacognostical studies reveal the macroscopical characters of Nigella sativa seeds. Phytochemical screening of the ethanol and aqueous extracts of Nigella sativa seeds revealed the presence of secondary metabolites like alkaloids, carbohydrates, proteins and amino acids, tannins, saponins, glycosidesand flavonoids. The ethanol and aqueous extracts showed good dose dependent free radical scavenging property. IC50 values for aqueous and ethanol extracts were calculated by DPPH method. Aqueous extract have shown more free radical scavenging power as compared to ethanol extract. Ascorbic acid was used as standard. In this experiment, abortion is induced by using pregnancy maintenance model. In contrast, no live foetus was recorded in the animals treated with mifepristone as well as the 400 mg/kg, p.o. body weight of the ethanolic and aqueous extract having live foetus. Whereas ethanolic and aqueous extract having dead foetus and there was no dead foetus in the mifepristone treated animals. The ethanolic and aqueous extract of Nigella sativa at doses of 400 mg/kg has abortifacient effects, supporting its uses in traditional medicine. Further studies on the isolation of bioactive phytoconstituents of Nigella sativaseeds and their mechanism of action are strongly recommended before its application to humans.

Titanium doped nanosized tin oxide photo catalysts are synthesized for the first time using simple co-precipitation method. The degradation experiment demonstrates the synergistic effect between adsorption and photo catalysis for the removal of methylene blue (MB) under the sun light for irradiation. The prepared photo catalysts are characterized by using X-ray diffraction, SEM and EDAX, UV-Vis Spectra and photo luminescent. The crystallite size is determined from XRD analysis and is found to range from 3.81nm to 18nm. The blue shift in the UV-Vis absorbance spectra confirms the quantum confinement of the samples. The substitution of Sn by Ti in the rutile structure increases the concentration of oxygen vacancies as it enhances the degradation of methylene blue dye under direct sunlight. The maximum photo catalytic removal efficiency of the synthesized samples for methylene blue dye is 95.6% in 45 min.

Thằn lằn bóng đốm (E. macularius) là một loài bò sát có ích trong các hệ sinh thái ở cạn. Tuy nhiên, thông tin về sinh thái dinh dưỡng của loài này ở Việt Nam nói chung và ở vùng cao nguyên Buôn Ma Thuột – Buôn Hồ nói riêng chưa được nghiên cứu nhiều. Sử dụng phương pháp súc rửa dạ dày để thu thập các mẫu thức ăn từ 295 dạ dày (149 con đực, 146 con cái) kết hợp với các số đo về hình thái cũng như các yếu tố môi trường. Kết quả nghiên cứu cho thấy chiều dài thân (SLV) trung bình của con đực trưởng thành lớn hơn con cái trưởng thành. Trong đó, chiều dài thân có mối quan hệ chặt với khối lượng cơ thể (BM) và các chỉ số hình thái khác của Thằn lằn bóng đốm. Thằn lằn bóng đốm đã sử dụng 17 loại thức ăn. Các loại con mồi yêu thích là bộ Cánh màng, ấu trùng côn trùng, thực vật, nhện, mối và bộ Cánh thẳng với tổng tần số xuất hiện chiếm 59,44%, 62,23% số mục con mồi và 75,33% về thể tích. Chế độ dinh dưỡng của cá thể cái đa dạng và phong phú hơn so với cá thể đực. Độ rộng miệng và chiều dài thân có ảnh hưởng đến kích thước và thể tích con mồi ở cả con đực và con cái (P<0,05). Kết quả này cho thấy chiều dài thân (SLV) và chiều rộng miệng (MW) có ảnh hưởng đến giới hạn kích thước con mồi đối với loài Thằn lằn bóng đốm.

Thằn lằn bóng đốm (Eutropis macularius) thuộc họ Thằn lằn bóng (Scincidae), đa phần Thằn lằn bóng đốm ăn côn trùng, ấu trùng gây hại do đó chúng trở thành động vật có ích cho nông, lâm nghiệp. Tuy nhiên, cho đến nay chưa có công trình nào nghiên cứu đầy đủ về đa dạng di truyền quần thể của loài Thằn lằn bóng đốm ở khu vực Tây Nguyên. Chúng tôi đã nghiên cứu đa dạng di truyền của 36 cá thể Thằn lằn bóng đốm thu ở một số tỉnh thuộc khu vực Tây Nguyên bằng kỹ thuật đa hình các đoạn khuếch đại ngẫu nhiên (RAPD). Các hệ số đa dạng di truyền như số allele quan sát được (na), số allele hiệu quả (ne), hệ số đa dạng di truyền theo Nei (h), hệ số đa dạng di truyền theo Shannon (I) của 4 quần thể nghiên cứu lần lượt là 1,9841; 1,2794; 0,1951 và 0,3283. Hệ số đa dạng nguồn gen trung bình giữa các quần thể (Hs) là 0,1692, chiếm 86,72% đa dạng nguồn gen của tổng các mẫu (Ht) là 0,1951. Hệ số đa dạng di truyền giữa các quần thể (Gst) là 0,1326 và dòng gen ước tính (Nm) là 3,2695. Mức độ tương đồng di truyền giữa các quần thể khá cao, dao động từ 93,46 đến 97,99%.
