Paying to Conserve Watershed Services in Pangani River Basin, Tanzania

Willingness to pay for watershed conservation: are we applying the right paradigm?

“…Unfortunately, the economic value to society of these ES are frequently undervalued and sometimes not captured along the PRB because of lack knowledge regarding the role that watershed ecosystems play in offering ES or because these ES are indirect and therefore, difficult to quantify. Thus researches to ensure that watershed ecosystems along the PRB are carefully conserved to ensure sustainable supply of ES and that these ES are properly documented and quantified are crucial (Lalika et al, 2015c). More importantly, it is high time to carry out empirical studies so as to document the people's WTP for watershed conservation.…”

“…Understanding of the values that people place ES is critical to making sound management and economic decisions (Lalika et al, 2015c). In many cases, markets provide an easy way for people to reveal value through their decisions to buy and sell ES.…”

Exploring the Implications of Modeling Choices on Prediction of Irrigation Water Savings

“…The literature covering ecosystem services in the region classifies downstream irrigation water as an ecosystem service worth conserving and proposes payments to redistribute benefits from irrigation water from downstream large‐scale farmers to upstream small‐scale farmers (Hipel et al., 2015; Lalika, Meire, & Ngaga, 2015; Lalika, Meire, Ngaga & Chang’a, 2015; Lalika et al., 2017). Such benefits are usually framed in terms of water saved for downstream use under more efficient upstream irrigation technology (IFPRI, 2016; Lein & Tagseth, 2009).…”
