A Predator-Prey Model with an Application to Lake Victoria Fisheries

Greater complexity in renewable resource models is achieved by acknowledging that species interact through a predator-prey relationship in which both species are harvested. The price of greater complexity is that traditional concepts, such as maximum sustained yield (MSY), have to be revised dramatically. Moreover, having chosen greater complexity, fishery biologists and other researchers must choose an explicit value for each fish, a rate of exchange of one species for every other species. Policy makers and social scientists in Tanzania, Kenya, and Uganda with a keen interest in Lake Victoria fisheries regard the resource as a tool for furthering socioeconomic goals, such as foreign exchange earnings, employment for women, and nutrition. Comparative analysis allows policy makers to understand the consequences of choosing these goals in addition to economically efficient resource use. Foreign exchange earnings, employment for women, and healthy people are other goals promulgated by Tanzania, Kenya, and Uganda in the management of Lake Victoria Fisheries. The conflicts among social goals are evident in the bioeconomic predator-prey model: a goal favoring a particular species reduces the sustainable harvest of another species. Data from Kenya are used to estimate the population dynamics equations.predator-prey, bioeconomic model, Lake Victoria, Resource /Energy Economics and Policy, Q22, Q28,

Capacity-building village sanitation committees accelerates and sustains communities open defecation free status

Since 2016, Amref Health Africa has been implementing the Kenya Sanitation and Hygiene Improvement Programme (K-SHIP) funded by Water Supply and Sanitation Collaborative Council (WSSCC) through the Global Sanitation Fund (GSF). The K-SHIP1 has formed and trained 6480 village sanitation committees (VSCs) on community-led total sanitation (CLTS). However, early to mid-2016, there was slow pace delivering villages ODF because VSCs` capacity-building was not emphasized and streamlined. To accelerate the pace, the programme innovatively resorted to capacity-build VSCs which enabled the K-SHIP to achieve more ODF villages (149 in 2016 and 410 in 2017). This is after ensuring key competencies are acquired by VSCs through a 2-day training and on-job-orientation on CLTS incorporating Sanitation Marketing and Equity & Inclusion during follow-ups. This paper aims to emphasise that to improve CLTS efficiency, sustainability and hence health outcomes and building up strong socio-economic-ODF-slippage-free communities, proper capacity building to VSCs is necessary
