    Although REDD+ is approaching its 10th anniversary, major impacts in terms of reduced forest loss are hard to document. Conservation practitioners and scholars are therefore increasingly asking why REDD+ has not delivered more tangible results. A recent Comment in Conservation Biology by Fletcher et al. (2016) addresses this question. We agree with Fletcher et al. that REDD+ has been hyped in some circles, which has created unrealistic expectations among policy makers and forest dwellers alike. Yet, we argue that Fletcher et al.

    Good estimates of ecosystem complexity are essential for a number of ecological tasks: from biodiversity estimation, to forest structure variable retrieval, to feature extraction by edge detection and generation of multifractal surface as neutral models for e.g. feature change assessment. Hence, measuring ecological complexity over space becomes crucial in macroecology and geography. Many geospatial tools have been advocated in spatial ecology to estimate ecosystem complexity and its changes over space and time.

    In the Tana River Basin in Kenya, six Regional Circulation Models (RCMs) simulating two Representative Concentration Pathways (RCPs) (i.e., 4.5 and 8.5) were used as input to the Soil and Water Assessment Tool (SWAT) model to determine the possible implications for the hydrology and water resources of the basin. Four hydrological characteristics – water yield, groundwater recharge, base flow and flow regulation – were determined and mapped throughout the basin for three 30-year time periods: 2020–2049, 2040–2069 and 2070–2099. Results were compared with a baseline period, 1983–2011.

    Rice-fish farming: A food security alternative Rice-fish farming is a biological or clean production system that consists of the simultaneous farming of rice and fish on the same land and at the same time; in other words, in the plots flooded for rice cultivation. Rice is the main product and has greater economic importance, whereas the fish is both a source of additional income and a protein supplement that improves the nutritional quality of farmers’ diets.
