1. Introduction. Land resources are vital for agrarian livelihoods. For many subsistence and smallholder farmers who do not possess the formal rights to own, sell, or use land for cultivation (Dixon et al., ), access to land is often determined by complex interpretations of local customary laws, traditional norms, and subsistence farmers, women constitute an increasing.

Weather extremes negatively affect socioeconomic developments in arid and semi-arid areas (ASALs) and increase vulnerability of residents to food and water insecurity. Thus, communities adapt to such extremes of weather using Traditional Ecological Knowledge (TEK) and/or Modern Technologies.

Modern farming technologies and land resource developments in ASALs have in past ignored TEK, and in. Trickle down approaches from areas which already have more favourable investment climates have not worked; moreover the potential for significant growth in these areas is now limited.

(Chapter ) Marginalized since Colonial Times. The ASALs cover nearly 90 per cent of Kenya's land mass and are home to nearly 30 per cent of its population. Under the optimal land and water allocation the groundwater use increases, which in turn mitigates the waterlogging and salinity problems of the command area.

The net annual return from the command area increased by more than 20% under optimal allocations. Water Resources Allocation: Policy and Socioeconomic Issues in Cyprus Phoebe Koundouri, Ekin Birol (auth.), Phoebe Koundouri (eds.) This book does not only aim to present and analyze the Cyprus experience in water resources management, using both local and world experts in the field.

Many other nations are encouraged to strive for the economic and resource-management standards that Kenya has already attained, yet the arid and semi-arid farmlands of Kenya suffer from multiple environmental problems associated with land-use change and development itself (Darkoh ; Deacon and Darkoh ; Mbithi and Wisner ).

Recently, water resources allocation got much attention across the globe since climate change and population growth pushed to their natural limits. Still, the scope of the problem becomes a research area in many regions of the world [7,8,9,10,11,12,13,14,15,16].

[C M Ondieki; Johnson U Kitheka; IGI Global,;] -- "This book addresses the hydrological processes of ASALs, climate change and variability, land use changes, floods and droughts, agriculture, integrated water resource management and sustainable.

Abstract Lack of water allocation plans in semi-arid river basins increases the risks of hydrological droughts. The Mukurumudzi river basin was experiencing extremely low flows which led to a water allocation assessment to quantify the available resource amidst competing demands from domestic, commercial and environmental needs.

Natural resource economics focuses on the supply, demand, and allocation of the Earth’s natural resources. Every man-made product in an economy is composed of natural resources to some degree. Natural resources can be classified as potential, actual, reserve, or stock resources based on their stage of development.

rural development is a critical area of activity, where improving access to land by the poor (especially women, minorities and other disadvantaged groups) who want to engage in agricultural pursuits is a key aspect which is often unrecognised and not well understood. This book, like others in the series, does not seek to be exhaustive but rather.

The Watershed Perspective Each type of land use has a varying effect on the hydrologic cycle, thereby affecting the people and the natural resources on a landscape.A watershed perspective can be used to scientifically study the effect of land uses on water and downstream ecosystems.A watershed is defined as a topographically delineated area drained by a stream system; that is, the total land.

Fostering productive development, including the provision of financing to improve agricultural production, develop agro-processing and non-agricultural businesses and sustainably manage natural resources.

The project will operate in 30 municipalities with high incidences of poverty and vulnerability in the semi-arid area of northern Bahia State. An optimal water resources allocation model was constructed to achieve the maximum comprehensive benefit for the river basin socio-economic and eco-environmental systems through allocating limited water resources under the constraint of land use reasonably and scientifically The optimal water resources allocation model consists of two parts, i.

Governors and MPs from poor counties have opposed the proposed resource allocation formula crafted by the Commission on Revenue Allocation. to the arid and semi-arid areas. To ensure that rehabilitated areas do not revert to their previously degraded state; technical interventions are needed to allow for a more intensive use of rangeland resources within enclosed areas.

The existing situation, the demographic characteristics and the structures of the production systems have been studied. It has emerged that the land'population ratio. In a new interactive, the Kenya Devolution and Resource Sharing Calculator, Mwangi Kimenyi examines the current allocation of resources to Kenya's county governments and invites governments to.

The Land Area of the World is 13, million ha. 4, million ha are classified as ‘agricultural area’ by the FAO (this is % of the Land Area).

The agricultural area use is divided into 3 categories: arable land (28% of the global agricultural area), permanent crops (3%) and permanent meadows and pastures (69%) which account for the. Bambara groundnut (Vigna subterranea (L.) Verdc.) is an indigenous legume crop, cultivated by subsistence farmers throughout sub-Saharan countries.

Research findings indicate that the crop has great nutritional and agronomic potential, but it remains scientifically neglected. A baseline study was conducted in seven districts in semi-arid regions of rural Zimbabwe to gather knowledge on.

Assessment of carbon pools in semi-arid forests of India is crucial in order to develop a better action plan for management of such ecosystems under global climate change and rapid urbanization.

This study, therefore, aims to assess the above- and belowground carbon storage potential of a semi-arid forest ecosystem of Delhi. For the study, two forest sites were selected, i.e., north ridge. The ability to effectively maintain the functions of the ecosystem is closely related to the assessment of land resources within a conservation-utilization balance.

Land degradation is one of the most significant environmental treats on arid region ecosystems in terms of the use of these resources. In this chapter, the aim was to attract the attention to land degradation processes in Turkey.Study on the Optimal Allocation of Water Resources Systems and the Comprehensive Utilization of Water Resources in Arid-Semiarid Multiple Mining Areas.

Savannas cover more than ten percent of the world’s land surface and more than fifty percent of Africa, providing browse to millions of mammalian herbivores (Scogings & Mopipi, ).Although herbivory is a major driver of ecosystem functioning in semi-arid African savannas plant-herbivore interactions are poorly understood (Skarpe, ; Scholes, ; Scogings, ).
