Credibility is the measure of how institutions are perceived as a result of autonomous endogenous patterns of interaction and power differences. It is not the tenure security in the sense of neo-classical economics that matters but the perceived security and whether developers have the assurance to retain the fruits of their investment. What matters in performance of institutions is not their form but their functions as it is determined temporally and spatially in terms of economic efficiency, stability and growth.

Slower than desired growth in crop yields coupled with rising food demand present ongoing challenges for food security in Africa. Some countries, such as Tanzania, have signed the Malabo and Abuja Declarations, which aim to boost food security through increasing crop productivity. The more intensive use of seed and fertilizer presents one approach to raising crop productivity. Our simulation study examined the productivity and economic effects of planting different seed cultivars and increasing fertilizer application rates at multiple spatial scales for maize in Tanzania.

The main goal of the paper is an evaluation of the dynamics of golf course (hereafter GC[s]) construction in the Czech Republic (hereafter CR) after 1990 and an assessment of the impacts and the consequences of the GCs on the landscape. The construction of the GCs was evaluated from the point of view of the physical-geography with regards to human geography aspects with a focus on an assessment in relation to climatic, soil, hydrological parameters, land use and financial aspects.
