“…Kegiatan antropogenik seperti urbanisasi, pertanian dan penggundulan hutan mempengaruhi karakteristik air permukaan. Penurunan kualitas air akibat kegiatan pertanian merupakan masalah global [2]. Permukaan perairan juga dapat dipengaruhi oleh faktor alam seperti curah hujan dan pelapukan batuan.…”

Tujuan penelitian ini adalah untuk mengetahui daerah yang berpotensi sebagai daerah resapan air di Kabupaten Pringsewu.Kawasan resapan air sendiri sangat penting bagi Kabupaten Pringsewu untuk menanggulangi banjir maupun kekeringan. Oleh karena hal tersebut, maka perlu melakukan pemetaan denganPemanfaatan Sistem Informasi Geografis (SIG). Sedangkan untuk penentuan nilai harkat bobot masing-masing parameter menggunakan metode Analytichal Hierarchy Process (AHP). Hasil penentuan kawasan daerah resapan air menggunakan metode scoring, pembobotan dan overlay dengan menggunakan 5 parameter yaitu tutupan lahan, curah hujan, jenis tanah, kelerengan dan formasi batuan, serta sudah dilakukan validasi di lapangan dapat disimpulkan bahwa sudah cukup valid atau daerah resapan air dapat diterima. Dengan faktor yang paling berpengaruh yaitu tutupan lahan. Kabupaten Pringsewu masuk termasuk kategori berpotensi sebagai daerah resapan air karena 50% luasannya masuk kedalam tingkat berpotensi sebagai daerah resapan air. Dimana luasan terbesar untuk tingkat berpotensi sebagai daerah resapan air berada di kecamatan Pagelaran Utara yaitu sebesar 17%, sedangkan untuk luasan terkecil pada tingkat berpotensi sebagai daerah resapan air berada di kecamatan Banyumas sebesar 2.3%.

“…Many residents turn to the stream water when the dry season sets in and the boreholes are dry. Contamination of Namukombe stream, boreholes, springs and bottled water in Uganda are well documented [6,[40][41][42][43][44][45], and thus, the results of this study agrees well with studies which indicated that ASGM communities in Uganda have contaminated ecosystems supporting their livelihoods [6,18,[46][47][48]. Water is an indispensable part of life on planet earth and the availability of sufficiently clean and safe water is an important aspect of a community [40].…”

Syanyonja village in the gold district of Busia, South East of the Republic of Uganda contain geologically epigenetic gold quartz vein deposits in carbonate-altered mafic metavolcanic rocks, deposited as quartz reefs in mineralized shear zones. In supracrustal rocks, alluvial gold is obtained from weathered auriferous quartz veins, which are of late orogenic granitic activity. The Syanyonja gold deposits have long been subjected to artisanal and small-scale gold mining (ASGM) by the locals for livelihood. This study determined the amount of mercury discharged with tailings into Namukombe stream, a major water body in Syanyonja village and investigated the impacts of ASGM on the mining population and the environment. Quantitation of mercury discharged with tailings was done by mass balance method. Field survey at the mining sites was done followed by administration of questionnaires to 50 stampeders in the village. The study indicates that about 8% of mercury mixed with auriferous materials are lost in tailings, accounting for an annual mercury release of about 1.757 kg into the environment. Socio-demographic results indicate that the majority of the mining population (64%) are male and ASGM have left health and environmental footprints, which directly or indirectly affects the population. The most common health problems among miners are malaria (36%) and abdominal pain (20%). The standard of living of the miners are evidently low, and most mines are characterized by school dropouts, prostitutes and thieves. Mining sites have deplorably poor hygiene, with evident burning of amalgams to recover gold. ASGM have been accompanied by wanton mowing down of vegetation, land degradation as well as mercuric pollution of water, air, land and aquatic ecosystems. It is suggested that the Ugandan government should re-enforce committees to follow up on ASGM activities, train artisans on sustainable gold mining using borax, magnets, sluice boxes as well as take up farming actively as an alternative.

“…In the former, inhabitants of the area have often protested against what they believe is an incremental process of declining water levels of the river (Mwakalila, 2011). In the latter, there is wider evidence of excessive concentration of nitrogen and phosphorous in the waters of Victoria Lake and the Nile ensuing from the use of agro-chemicals (Munabi, Kansiime, & Amel, 2009).…”

Contracting Sugarcane Farming in Global Agricultural Value Chains in Eastern Africa: Debates, Dynamics, and Struggles

Integrating smallholders within global agricultural value chains through contract farming has regained momentum in the development agenda, particularly in Africa. Governments, corporate agri-business, and global development institutions have embraced sugarcane as a suitable commodity to promote the integration of smallholders within commercial agricultural circuits so as to improve the prospects of rural development and reduce rural poverty. Influenced by the new institutional economics paradigm, win-win scenarios in which agribusiness companies and smallholders reciprocally benefit—the former by getting regular and standardized quantities of produce; the latter through secure access to the market—are advocated. However, little evidence of success in contract farming has been provided. By exploring the socio-ecological implications of contract farming within two major agro-industrial complexes (in Uganda and Tanzania), we demonstrate that the incorporation of smallholders in these schemes is spearheading dispossession from below, selection of most competitive producers, ecological degradation, social differentiation, and conflict.
