Rural and Agrarian Transformation 1984–2018 in Three Marginal Villages in Njombe Region, Tanzania

When the author of this chapter first visited the region he encountered a place that was characterized by very high levels of poverty. These villages had not been able to benefit from state investment in maize production. However, changes in agricultural production, migration of people outside the area, and remittances, and in particular the explosion of tree farming, tomatoes, and potatoes in a relatively rich area, combined with infrastructural improvements, have been transformative. Change here has been driven by a mutually interlinked set of processes entailing agricultural transformation involving changing farming and rural transformation in a changing rural economy. This is visible in changes to asset ownership as well as relational and social well-being.

The essay discusses the theoretical implications of ecological restoration in landscape architecture. The study presents a management plan for highly damaged peatlands in the Isle of Skye in Scotland, where the habitat is threatened by a radical forestation process. Being a natural carbon stock, damaged peatlands are a major source of greenhouse gas emissions. The project suggests gradually turning the case-study area's economy from tree farming to tourism, making the most out of the unique biodiversity of peatlands. The proposal traces a chronological activation plan of a touristic network that will run in parallel with the restoration of peats, native broadleaf forests, heather and cotton-grass meadows. Depending on the ability to recover of different soils, the restoration plan intends to gradually activate new dynamics in the landscape. The result is a stable “novel ecosystem” whose key interactions and processes are induced by new biotic and abiotic conditions. The article investigates and discusses possible strategies to develop a new kind of wilderness that differs from any previous condition and emerges from an alternative land use.

Olive Pulp and Exogenous Enzymes Feed Supplementation Effect on the Carcass and Offal in Broilers: A Preliminary Study

Nowadays, there is an increasing interest in the exploitation and valorization of agricultural food waste and by-products. At the same time, the growing demand by markets worldwide, especially in Africa and Southeast Asia, can justify the growing interest in the use of by-products for the poultry industry. Olive pulp is one of the most interesting by-products of olive tree farming (typical of the Mediterranean area), being a good source of many biologically active compounds with antioxidant, antifungal, and antibacterial properties. The presence of processed olive pulp in the diet showed to be effective in increasing the weight of specific carcass and offal traits. This work aims at studying olive pulp as a feed supplement in poultry nutrition, by focusing on the effects on broiler carcass and offal. Olive pulp (OP) is one of the by-products of olive tree farming, being the residue of olive cake after it is dried. To evaluate the effects of OP in a diet supplemented with different levels of a commercial enzyme (ENZ) blend on broiler carcass and offal traits, three hundred male broiler chicks (Ross 308 lineage; one-day-old) were divided into ten treatment groups according to a completely randomized design. The treatments diets contained: unprocessed OP (50 g/kg, 100 g/kg, 50 g/kg with ENZ, 100 g/kg with ENZ), processed OP (50 g/kg, 100 g/kg, 50 g/kg with ENZ, 100 g/kg with ENZ), and control groups (without OP, and without OP with ENZ). The OP processing increased breast percentages in broilers. Supplementation with ENZ did not change any of the studied carcass or offal trait values. The presence of OP (50 g/kg) in broiler diets increased the eviscerated carcass, leg, and neck percentage values. The presence of processed OP (50 g/kg) in the diet showed to be effective in increasing the weight of specific carcass and offal traits.

Impacts Socio-Economiques De La Culture De L’anacarde Dans La Sous-Prefecture D’odienne (Côte d’Ivoire)

Introduced in the Ivorian agriculture from 1960, the farming of cashew tree is now rapidly developing, precisely in the Center and North of the country. Odienné sub-prefecture occupies an important place with an estimated production of 33,006 tons in 2015. This increase in production is the consequence of the price per kilogram which increased from 225 fcfa in 2011 to 350 fcfa. These prices contribute to the improvement of the living conditions of the producers and the schooling of their children. But the development of cashew tree causes conflicts between cattle breeders and producers. These conflicts tend to undermine the social cohesion between communities. The objective of the study is therefore to evaluate the economic and social impacts of the cashew tree farming on producers in Odienné sub-prefecture. The survey has favored the combination of qualitative and quantitative approaches.
