    Feed and grazing management affect both the quantity and quality of animal manure and consequently nutrient cycling in the mixed crop-livestock systems in West Africa Sahel. Dietary measures can significantly influence the composition of manure and hence it’s agricultural value. High nutrient feed will generally result in higher nutrient content of the manure whereas a decline in feed quality will generally lead to increase in the indigestible fractions in the feeds.

    Tetra Tech’s land tenure and property rights experts examine how weak land and resource governance can fuel drivers of violent extremism. With a focus on the African Sahel, this new issue brief finds this dynamic is especially prevalent when land and resource governance challenges are coupled with environmental disruptions, resource scarcity, or migration.

    Nigeria

    This report documents the violent clashes between members of farmer communities and members of herder communities in parts of Nigeria, particularly in the northern parts of the country, over access to resources: water, land and pasture. It also documents the failure of the Nigerian government in fulfilling its constitutional responsibility of protection of lives and property by refusing to investigate, arrest and prosecute perpetrators of attacks.

    The Kuri cattle breed is found on the shores and islands of Lake Chad. Its main habitat is in southern Chad and north-eastern Nigeria but the breed is also found in northern Cameroon, in Niger and, to a limited extent, in the Central African Republic. The Kuri are also known as the Baharie, Bare, Borrie, Boudouma, Dongolé, Koubouri, Buduma or White Lake Chad. The importance of the Kuri lies not only in its unique physical characteristics but also in its meat and milk production potentials. The breed is so acclimatised to the environs of Lake Chad that it is unable to survive elsewhere.

    In Africa, where most agriculture is rainfed, crop growth is limited by water availability. Rainfall variability during a growing season generally translates into variability in crop production. While the seasonality of rainfall in the drier rangelands can play a significant role in productivity, rain-use efficiency (RUE)—the amount of biomass produced (in kilograms of dry matter per hectare) per millimeter of rainfall—also drives production.

    Drought is one of the major climatic hazards impacting on the various sectors including crop and livestock in the West African Sahel. Pastoral and agro-pastoral communities in the region are regularly affected by drought, with vulnerability differing with gender, age, wealth status (access to cropland and livestock endowment), geographic location, social networks, and previous exposure to drought. Effective interventions require regular monitoring of vulnerability to drought, for which various quantitative and qualitative approaches exist.
